‘THE IRON AGE THURSDAY, New Model Two-Spindle Profiling Machine. The photograph reproduced herewith in half-tone, to gether with the drawings, illustrates a new two-spindle profiling machine for metal work, recently placed on the market by the Pratt & Whitney Co. of Hartford, Conn. The machine is of the same design as these being built for the Government arsenal at Rock Island. It is compact, occupying smal! amount of floor space, and seems to be an exceptionally rigid machine and ecapabl J LY 17, 1902 side only of each \ single V Each spindle is driven by means of a large worm and Kiys. 2 and 3, This possibility is obviated on the and flat track construction. worm ger, the worm being 6 inches di- meter and the gear 4 inches diameter, thus providing The pitch of the worm is such as to increase the speed of the worm gear at a rate of 3 to 2, instead of giving a reciuction, thus permitting of high spindle speeds with- out excessive speed to the driving shaft. large tooth contact and ample wearing surfaces. The worm is NEW MODEL of withstanding severe usage. The bed is in the form of a column and contains two large tool cabinets and a removable tank for oil orotherlubricant. It is quite heavy and thus provides a firm support for the working parts above. The bed is provided with suitable troughs for properly carrying off lubricant to prevent wasting. The table is beld down to the bed by two straps. It is fitted to the bed by a V at the left and has a flat track at the right, instead of two V’s. This construction has been adopted on a number of Pratt & Whitney Company’s tools, as a long, narrow bearing resists the twisting tendencies much better than a wide bearing of equal length. It is further true that two V’s, when worn, and frequently when new but under cutting strains, do not fit on both sides of each V, but are apt to fit on the outer TWO-SPINDLE PROFILING MACHINE made from a steel easting and the worm gear fron» phosphor bronze: Both the worm and worm gear have hubs journaled in bearings independent of the driving shaft and spindle bearings. The cutter spindles are thus sensitive close fitting to the worm and worm gear, aS regards tooth contact, as is possible. The worm is driven by two long keys, located in the shaft diametrically opposite to each other; this balances the drive. Ball thrust bearings are provided at each end of the worm and worm gear, and the cutter spindle may thus be rutated with equally good results in either diree- tion, producing a very free running and durable drive. The cutter spindles are of steel, are ground and run in bronze bearings. ‘The lower bearings are solid and of conieal form.

The spindle end thrust is taken at the lower bearing by babbitt metal washers. The spindles have been run as high as 1200 revolutions per minute. Each head when not in use is raised by a heavy inclosed spiral spring, and is quickly lowered to bring the cutter into proper relation with the work by a lever and clamped to position.

When properly adjusted the two parts of the member may be firmly clamped together by conical studs. The right hand spindle head is provided with an extra former pin hole located on the opposite side of the spindle from that in which the pin regularly fits. The centers of the two holes are located equidistant from the center of the spindle and in the same plane with it.

July 17, 1902 THE Status of the Various Reciprocity Treaties. All But One Expire This Summer. WASHINGTON, D. C., July 15, 1902.—The State Depart- ment is in receipt of inquiries from representatives of commercial interests in various parts of the country as to the status of the French treaty and other pending reciprocity conventions, in view of the adjournment of Congress without action thereon, and as to the general outlook for these treaties in the future. The information which the Department feels at liberty to impart on this subject is not as full as it might be be- sause of the diplomatic aspect of the matter, but, in an unofficial statement made to the correspondent of The Iron Age, a representative of the Department has given some interesting details. Of the eight pending treaties, all but one, that be- tween the United States and the Dominican Republic, will expire before the reconvening of Congress in De- cember. All of these treaties have been renewed two or three times, and the last time under extraordinary circumstances which then seemed to indicate that no further renewal would be solicited by either of the two contracting parties. The Senate Committee on Foreign Relations has taken no action on any of the treaties and apparently intended to ignore them, and as a result Commissioner Kasson recommended to the Secretary of State that no further action be taken by the Depart- ment looking to their renewal except upon the initiative of the Government with which they were negotiated. In each case, however, these governments solicited the renewal of the treaties and the State Department promptly agreed to their extension, not only as an act of courtesy but in the hope that some of them would be ratified by the Senate. The extension was then made for 18 months, an unusually long period, in order that none of them should expire until after the adjournment of the session of Congress which has just terminated. It will be remembered that during the recent session the Senate Committee on Foreign Relations, by a very close vote, cast under somewhat peculiar conditions, re- ported favorably to the Senate all of the treaties except those with Jamaica and the Argentine Republic, which by a large majority were indefinitely postponed. also A New Argentine Convention Possible. As to the renewal of these treaties the correspondent of The Iron Age is in position to make a definite state- ment. The pending conventions with Jamaica and the’ argentine Republic will not be renewed and for other reasons than because of their formal rejection by the Senate Committee. The trade with Jamaica, which the treaty was designed to divert to the United States, is ab ut to be directed to Great Britain by the establish- ment of steamship lines, and the people of the island are no longer in need of a market in the United States. The Argentine treaty, against which the wool growers have raised such strenuous protests, not only lacks sup- port in Congress, but the State Department is now dis- posed to regard as a serious error the fact that Minister sSuchanan in negotiating this treaty exceeded his in- structions by making a 20 per cent. concession on wools of Class 1 as well as Classes 2 and 3, to which his au thority was restricted. It would not be surprising, how- ever, in view of the facts concerning the Argentine treaty that a new convention should be negotiated simi- lar in all respects to that now pending except with re gard to the concession on wools of Class 1, which would be eliminated. The shoe and leather manufacturers of the United States are strongly in favor of the ratifica- tion of the Argentine treaty, which reduces the duty on Argentine hides imported into the United States by 20 per cent., and they also have the support of the wool manufacturers of New England. Other Treaties Expected to Be Renewed. With regard to the French and other reciprocity treaties it can be stated that the United States will not seek their renewal, and, unless the foreign governments IRON AGE. 3 concerned take the initiative, they will be permitted to expire. It is expected, however, that several of these governments, including that of France, will suggest the extension of those conventions, and the State Depart- ment, with a of keeping the subject alive, will probably the Special interest naturally centers about the French treaty, which is the most important on the list and which will expire in ten weeks, during the summer holiday season of the diplo- matie corps. It is quite probable that no renewal will be agreed to before the date of expiration, but in this connection the interesting statement is made that with regard to all these an understanding exists under which any time after their expiration, whenever, in the judgment of the Sec- retary of State, it is expedient to take this action. view acquiesce in requests. conventions they may be revived at The Administration Still Favors Reciprocity. It may be frankly stated that the Administration does not count upon the ratification of any of the pend- ing treaties by the present Congress, which will termi- nate March 4 next. The officials of the State Depart- ment, however, are anxious that the reciprocity princi- ple should not be lost sight of for two important rea- first, because during 1903 the reciprocal trade conventions between the principal countries of Europe will expire and will be renewed on bases which are be ing negotiated and in which the United States has a heavy stake; and, second, it is regarded as a foregone conclusion that within a comparatively short period Congress will be compelled to comprehensively revise the present tariff. If the pending reciprocity treaties fail ignominiously, and no others are negotiated, the United States will be placed at a great disadvantage in dealing with foreign countries after their reciprocal trade relations have been readjusted by the new con- ventions now in prospect. The Administration hopes that Congress will be wise enough, in the event that all the pending treaties fail, to provide a new »asis for reciprocity in the tariff revision which, it is thought, can- not be much longer postponed. Suggestion of Maximum and Minimum Schedules, In this connection there is a revival here of the sug- gestion that maximum and minimum schedules shall be prepared by Congress when the tariff revision is made, which would at once establish a basis for reciprocity negotiation. With such a tariff in force the amount of the concession to be made would be regulated by Con- gress, and the State Department would be limited to the selection of the particular items on which the lowest rates would be conceded to the country with which a reciprocal convention happened to be in process of nego- tiation. It can be very emphatically stated that the President and his advisers have not abandoned the prin- ciple of reciprocity and that they hope to see it estab- lished in some practical manner which will make it a comparatively easy matter to extend it wherever it will be of advantage to the American export and import trade. Sons; The Cuban Treaty. Special attention will be directed to the importance of reciprocity with the Presi- dent’s action in sending to the Senate a treaty providing for reciprcecity with Cuba. This will go to the Senate Committee on Foreign Relations in the ordinary European countries by treaty course of events, rather than to the Committee on Rela- Cuba, which of the Spooner reciprocity bill; and it is the purpose of those who are opposing Cuban reciprocity to place this treaty tions with recently had charge on the executive calendar immediately behind the French treaty, so as to force consideration of the French treaty in advance of all others. As Senator Aldrich proposes to insist upon a reference of the French treaty to the Finance Committee to determine upon the motion will be made as to the Cuban treaty, and thus the two conven- its effect revenues, a similar tions may be kept in the same category until disposed of. Chairman Payne of the House Ways and Means Committee has added to the interest in the situation by a statement made here this week to the effect that both the Cuban and French treaties will require approval by 4 THE the House as well as the Senate before becoming opera- tive. The Senate has repudiated this idea, and a very lively contest with regard to it is in prospect. w. L. C. The Selection of Steel for Various Articles.—II.

Bergh of Gothenberg sends the following translation from a recent issue of the Trading and Shipping Journal, of that city: At the meeting of the lron Manufacturers’ Association, Engineer F. A. Kjellin and Mr. Benedicks gave some very interesting informa- tion about the production of electro steel at Gysinge. The problem of smelting steel by electricity has for a long time attracted the attention of inventors, and ex- periments bave been made here. By the advice cf En- gineer Kjellin, Mr. Benedicks decided in 1899 to build at CGysinge an electric steel furnace without electrodes. In the latter part of February, 1900, the first furnace was finished and ready for trial, and after a few experi- ments the first ingot was produced. The steel was found to be of excellent quality. The problem was thus solved technically, but not economically; for, with the dynamo of 78 kw. used, not more than 575 pounds of steel were obtained in 24 hours, and in the furnace there was not room for more than 176 pounds. A larger furnace was seen to be necessary, and this was completed in Novem- ber. 1900, and proved to be a great improvement. In the second furnace, which held 397 pounds, from 1220 to 1340 pounds of steel were produced in 24 hours. The Gysinge sulphite factory burned down on August 11. 1901, and it was decided to build steel works in its place and to use the water power available there. For the steel furnace there was utilized a turbine of 300 horse- power, with direct coupled generator. The new furnace is to huvld 3970 pounds, and the production is estimated to be at least 1500 tons a year if charged with cold raw material. July 17, 1902 THE Engineer Kjellin said that the steel produced is of su- perior quality and characterized by strength, density, uniformity, toughness, and the ease with which it can be worked in cold, unhardened condition, even when con- taining a very high percentage of carbon. Compared with other steel, it also has less tendency to ecrsck or warp when hardened. The reason why this steel in cer- tain qualities differs from: other steel, especially in its softness when unhardened, is considered to be its free- dom from gases. The manufacture of special steel, with nickel, chrome, manganese or tungsten, will, of course, not meet with any difficulties. The chrome steel and tungsten steel produced at Gysinge kas proved to be ex- cellent for lathe tools. When used for permanent mag- nets, the Gysinge tungsten steel has been found tc give stronger magnets than other tungsten steel and has not warped in the hardening. From estimates made, it has been ascertained that the furnace used at Gysinge, which is simple in con- struction and easily managed, has prospects of compet- ing, as to cost of operation, with the furnaces heretofore used for fusion of steel, especially as it yields steel of a better quality. For Sweden, with its good ores and large supply of water power, the electric method of smelting steel ought to be of great importance, and abroad, where blast furnace gas is becoming a cheap source of power, it ought to come into extensive use. After the lecture, Axel Wahlberg made some state- ments concerning tests of steel ingots from Gysinge, which had been found to be uniform and homogeneous. Microscopic examinations had indicated that there was no difference between the electro steel and crucible steel, which was so much more remarkable as the elec- tro steel in other respects had different qualities. << ———___ A New Manufacturing District at Niagara. The City of Niagara Falls was formed by merging the former village of Niagara Falls and Suspension Bridge and a small section of the town of Niagara into one municipality, and the power development has up to this time been confined in its application principally to that section fuimerly in the village of Niagara Falls and the town of Niagara. The territory that was known as Suspension Bridge lies to the north, and while it has long been intimated that this section would some day grow to greatness through the power development noth- ing that would assure this has occurred until within a few days. Now, however, all the brightest hopes ap- pear about to be realized. \ When the Niagara Fails Hydraulic Power & Mfg. Company acquired possession of the surface canal in 1877 there was considerable land in the deal, but much of this was sold off, and while a very large block was retained by the company for factory sites, the develop- ment of power in recent years has brought so many in- dustries to Niagara that the canal company have seen the necessity of going out on the northeast, or Suspen- sion Bridge side, of the city, and purchasing a large block of land for a new industrial section. Report gives the number of acres so purchased from 100 to 400, and it may be that at this writing the full extent is not known. On the property so purchased the Niagara Falls Hydraulic Power & Mfg. Company will establish a new industrial section, and it is already assured that it will grow rapidly. One thing going to show how substantial the move- ment is is found in the fact that the Carter-Crume Com- pany, manufacturers of the country’s supply of counter check books, announce that they have bought 5 acres in the new section, and will at once proceed to erect a factory that will cover over 3 acres. The present plant of this company is located on.the lands of the Niagara Falls Hydraulic Power & Mfg. Company on Main street, and while it has considerable room the company’s business has outgrown it. Coupled with this news comes the announcement that when the Carter-Crume Company move to their new plant, the William A. Rogers, Limited, will then occupy the present factory building of that company. IRON AGE. 5 Now the William A. Rogers, Limited, have a plant ad- joining the Carter-Crume Company, the same capital be- ing interested in the two concerns. It is intimated that when the new quarters are available the William A. Rogers, Limited, will move their plants to Niagara from Northampton and New Bedford, Mass., and also from Oneida, N. Y., in order that the business may be concentrated under a single roof. The new manufacturing section which will be es- tablished by the Niagara Falls Hydraulic Power & Mfg. Company will have excellent railroad facilities, and it will be a comparatively easy matter to transmit power to the section from the company’s generating plant. It is considered likely that the company will very soon an- nounce their intention to erect a new power house in the gorge close to the water’s edge, a short distance be- low the present power house. To-day from the several mills now using water from the canal there is consid- erable waste passing from the wheels to the débris slope and then into the lower river. The little waterfalls so formed are picturesque, but it is altogether likely that this scene of to-day will be unknown in the near future, when this waste has been captured to again passthrough turbines that will actuate mighty generators in a new power station.

The four-way valves are made with four ee ee Ete THE PUBLIC HYDRAULIC VALVE. plugs or pistons. The operating serew is cut compound with a right and left hand thread, and the nuts are in two and four sections for three and four way valves, re- spectively. The right hand nut deseends while the left hand nut ascends, or vice versa, by moving the lever one way or the other. The use of this screw eliminates all slamming of flanges and water hammer, the result be- ing the absence of shock to pipes and connections. It is also practicable to use metallic seats which have a long life. If for any reason the valves become cut, re- seating can be done in a few minutes by using a reseat- ing coil, or the old one ean be replaced by a new one without disturbing the valve. The leather cups used for the packing plugs will give service for months, as they are subjected to very little wear. The valves are easily operated and balanced. The smallest motion of the lever will reverse them and a piston in a cylinder can be moved fractions of an inch either way and loads held on the crane indefinitely without the attendance of an operator. There can be no leak in the valve which the operator cannot discover. ces ~~ ee a= er ogee Cert se 6 THE IRON AGE. A New Bag Conveying System The New Jersey Foundry & Machine Company of 9-15 Murray street, New York, have just completed for the Walter Baker Company, Limited, of Milton, Mass., a conveyor for handling 250 bags per hour, weighing 300 pounds each. The problem in this case was to take the bags from cars on the track at the side of the build- ing to the second floor of a warehouse about 60 feet wide and several hundred feet long. The bags were to be delivered in such a way as to reduce the labor required to stack them in piles to a minimum. A bag elevator. Fig. 2, is arranged vertically just outside of the building, carrying the bags on sets of curved projecting arms mounted on an endless chain which runs between guides. This elevator receives the bags directly from the car and discharges them into an inclined chute extending into the building to the center bin, and lying wholly above the bottom chord of the roof trusses. ‘he chute leads to a conveyor, Fig. 1, running the fuli length of the building and carried by trussed frames resting on the bottom chord of the roof trusses. The conveyor has on top a carrying platform made of wooden strips so as to present a practically continuous fioor. At either side of the longitudinal conveyor is a cross conveyor, spanning the space from the center of the building to the side walls, and having its carrying platform at a lower level than that of the main con- veyor. These cross conveyors form each a self con- tained structure, running on tracks extending the full length of the building, attached along the side walls and along the center conveyor trusswork. The system of conveyors thus covers the whole space of the loft and permits transferring bags from the elevator to any de- sired point., The operation will be readily understood. The la- borers in the car toss the bags into a stationary rack placed in the path of the projecting arms carried by the elevator chain. These projecting arms are so spaced as to pass between the bars of the rack, and they pick up the bag and carry it to the top of the building. Here the bags fall into the chute, down which they slide to the longitudinal conveyor, which carries them along to any desired point. The bags are unloaded from the conveyor by inclined guide beards, shown in Fig. 1, which may be fastened at any point, and which shove the bags off onto a short slide leading to the cross con- veyor. from the latter they are in turn unloaded by another guide board at the point desired, and by way July 17, 1902 is involved.

The only manual labor that remains to be done is to slew them around into proper stacking position. The feature of difficulty in the design of this plant was to so construct the horizontal conveying platforms that the bags could be successfully slid over the side by the stationary guide boards without risk of catching and tearing. Its successful solution makes the plant of particular interest to engineers having to solve convey- ing problems in which the handling of material in bags wheels attached by hanger pieces to the conveyor chain. The latter, in turn, carries on malleable iron shelf blocks the wooden strips that compose the platform of the con- veyor. Each pair of platform strips also carries hort- zontal guide wheels, which maintain its alignment by bearing against a longitudinal angle adjacent to the rolier track. The carrying wheels of the conveyor chain also support the chain on its slack or return side, bear- ing for this purpose on a longitudinal shelf angle at- tathed to the lower chord of the truss frame. The guide board is fitted with projecting strips of July 17, 1902 THE wood running along the face and pitching slightly up- ward toward the discharging end of the board, the board itself leaning backward a little. The whole construction is intended, in connection with the smooth horizontal surface of the conveyor platform, to prevent the bags being drawn under the guide board when they strike it, and to discharge them in proper manner upon the skid- way. The whole machinery is electrically driven. Worcester Industrial Notes. Machinists’ Strike Ended. Worcester, Mass., July 14, 1902.—The strike of the mackinists was formally declared off at a meeting of the renmants of the Worcester Machinists’ Union Wednesday night. The vote was practically «anani- mous, only a few hotheads voting uo on the question. Maurice W. Landers of Hartford, Conn., fifth vice-presi- dent of the National Association of Machinists, in speak- ing of the result of the strike, said: “ Worcester is a bad city for unions.” Mr. Landers has done everything he could to prolong the contest, but seven weeks was the limit. In fact, the bulk of the strikers were already at work in their old places. Many of the strikers have been taken back. and this week “No help wanted” signs will be posted at the doors of the shops where strikes have been on. The F. E. Reed Company and Prentice Bros. Company, who were hardest hit by the strike, are already running practically full again. Inquiries from customers have been received in large numbers during the last week or ten days, and the manufacturers are feeling confident that large business is before them. They have been injured financially by the strike. but are very well content so long as they have won the bat- tle with the union, not only without conceding a single point. but with the result that the Worcester Machinists’ Union is practically dead. The employees are delighted that they are at work again. The only disappointed ones, apparently, are the leaders and those whose jobs have been taken by men hired from outside the city during the strike. The men are dropping out of the union, saying they have had all they want of that sort of thing. Contract Placed for the Deering Steel Plant. The Deering Harvester Company of Chicago have placed a contract with the Morgan Construction Com- pany of Worcester for a merchant steel mill to be lo- cated on the Calumet River, at Chicago. The Deering Company have had difficulty in getting merchant steel rolled to exact size. Some parts of their machines are made of unturned steel, and exact rolling is necessary. Because of trouble experienced in the past the com- pany determined to build a steel plant and merchant mill of their own. Julian Kennedy of Pittsburgh has the contract for the steel plant and blooming mill, the Morgan mills taking the blooming mill product and roli- ing it into steel of exact diameter for the purposes of the company, which means cylinders almost as perfect as the product of an engine lathe. The Morgan mills have produced this result in other places, and the company feel no anxiety over the work of the new Deering mill. The Morgan Construction Company will also furnish a number of gas producers for the steel furnaces. Minor Notes, The American Machine Screw Company, of which the Worcester Machine Screw Company form one of the constituent parts, have decided not to build the big new plant at Detroit as planned. In its place the com- pany will build a considerable addition to the present shops at Detroit. The scheme of the new plant is not abandoned, but postponed for the present. The com- pany report that they are doing an exceedingly large business, and certainly the Worcester shop was never busier than it has been for the past year and more. The McCloud, Crane & Minter Company, the other Worcester machine screw concern, also report business as un- precedentedly good. The Howard Bros.’ Company, manufacturers of card clothing, have let the contract for a large addition to [RON ~ ‘ AGE. their factory at Worcester. The new building will cover 10,000 square feet of land, and will be four stories and a basement in hight. The material will be brick. The cost of the building will be $40,000. The Howard Bros. Company are independent, their principal competitor being the American Card Clothing Company, the com- bination of New England card clothing manufacturers, most of whose factories are in Worcester and the neigh- boring town of Leicester. The Howard Bros. Com- pany have prospered, as is indicated by the building of an addition which will more than double the room. New machinery will be installed and the capacity of the factory greatly increased. The business was estab- lished in 1866, The Lorain Steel Company have a track weiding out- fit at work in Worcester, on the lines of the Worcester Consolidated Street Railway Company. Already some 12 miles of track have been welded, and the work will continue until the end of the season; the results ob- tained being such as to induce the Consolidated to con- tinue welding all over the system, so far as possible, where new rails have not been laid within a year or two. = The foundry of Heywood & Wilson, at Fitchburg, Mass., has been bought by Joseph Pereaut of that city, who will conduct it in connection with his other foundry. The Worcester Surprise Spring Company of Worces- ter have been incorporated under the laws of the State of Maine, with an authorized capital stock of $40,000. The company will take the business conducted by a firm of the same name, and will manufacture spring beds and iron bedsteads. The officers of the company are: President and treasurer, Bert H. Prior, who with ©. 8. Yeaw and W. G. Prior will constitute the Board of Directors. The Spencer Wire Company have added a depart- ment for the manufacture of tacks and will devote a portion of their new building to the purpose. The soft coal situation does not seem to grow serious in Worcester. The quality of the coal received is wretched, but there is enough of it for the present. The Washburn & Moen Department of the Ameri- can Steel & Wire Company are almost as busy as be- fore the summer came. The big works shut down July 4 and the next day, that being Saturday, but outside of this little vacation the works are running full time with full force of men. The same condition of business exists at the Morgan Spring Company, Spencer Wire Company and Wright & Colton Wire Cloth Company, and from Clinton the report is that the Clinton Wire Cloth Company are as busy as ever. a % ——— The Holthoff Machinery Company.—The new plant of the Holthoff Machinery Company, at Cudahy, Wis., has been completed and was in active operation July 1, although not to full capacity. The pattern and machine shops will start up gradually and it is expected to have all machines ready and in operation about the middle of the month. The shops have been equipped with the most modern machinery, and special attention has been given to the boiler shop, which is fitted up for manufac- turing all classes of boilers and heavy sheet metal work. It is intended to build the internal fired boiler with Morison corrugated furnace, as well as heavy tank work of all kinds. The machines in the shops consist of the following: One Hilles & Jones heaviest plate bending roll, one No. 5 single punching machine, one hori- zontal punching machine, one small bending roll, one R. D. Wood’s sectional flange press, triple power hy- draulic riveter, hydraulic 50-ton crane, accumulator, a Lennox rotary bevel shear and splitting shear, 1500-Ib. Bement steam hammer, rapid action press, and other small tools to correspond. The company report a large number of orders already on hand. <> Catalogues Wanted.—J. C. Boyd, who has recently established himself at Lebanon, Pa., as consulting and contracting machinist, making mill, mine, railroad and blast furnace equipments his specialty, is desirous of receiving catalogues, price-lists, &c., from machinery and supply manufacturers. > 4 ud Buildings for the National Bureau of Standards. WASHINGTON, D. C., July 15, 1902.—Within the past week the work of construction of the buildings for the new National Bureau of Standards has been begun on Plans which when fully completed will represent an outlay of more than $1,000,000. The two buildings for which appropriatious are now available will cost $365,- 000, but the complete scheme contemplates several ad- ditional buildings, for which the appropriate committees of Congress lave practically pledged the money when needed. The first building to be erected will be known as the mechanical laboratory. It will be three stories in hight, 135 feet long and 50 feet wide, and will contain the power and lighting plant, storage batteries, special alter- nating current machines for experimental and testing purposes, the refrigerating plant, the heating and ven- tilating plant, auxiliary apparatus, the machine shop and carpenter shop, as well as laboratory for heavy elec- trical testing, photometry, gas and water meter testing. In the boiler room two 125 horse-power boilers will be installed, space being provided for doubling this ca- pacity. In the dynamo and engine room, two 80 horse- power high speed engines, each direct connected to two 25-kw. direct current generators with special alternators, The floor space will admit of doubling this power plant whenever necessary. The latest devices will be employed in the combined heating and ventilating system. The air will be supplied to the various rcoms by means of ducts, with the aid of electrically driven fans, the temperature of any room in either building being independently controllable by a thermostatic damper at the bottom of the respective flues, where the heated or artificially cooled air will be mixed with the air from without. The ducts are so pro- portioned as to permit a complete renewal of air every 15 minutes. In winter the air to be heated will be passed over coils fed with exhaust steam, and in summer will be cooled by coils through which cooled brine is circu- lated. To cool the air and to provide artificial ice a re- frigerating plant of 30 tons ice melting capacity will be installed. Although the building will be used only a portion of the 24 hours, provision will be made for fully utilizing the refrigerating capacity. An instrument shop will also be contained in this building and will be equipped with the latest types of motor driven precision and engine lathes, milling ma- chines, shapers, drills, presses, &c. A liquid air plant will be installed with a capacity for all experimental needs likely to arise and an electrie storage room will be fitted up for heavy current testing. The general equip- ment of the mechanical laboratory will be designed for power and instrument tests and it is predicted that the demand for this work will increase so rapidly that the additional buildings planned for will be needed within a very short time after the laboratory is ready for occu- pancy. The main building, which will include the office of the director of the bureau, and the construction of which will proceed simultaneously with the mechanical labo- ratory, wil! be four stories in hight, approximately 150 ‘feet long and 50 feet wide, and will contain about 50 rooms, all equipped with apparatus for verification work and for special investigations, and provided with gas, electric lights, compressed air, suction, hot and cold water, as well as with a number of independent elec- trical circuits, so that electrical currents of any desired character may be obtained. The importance of tempera- ture control in a physical laboratory has long been ap- preciated, and it is especially desirable in an institution where standardizing work is to be done, as nearly every result depends at least to some extent upon the tempera- ture at which the measurements are made. According- ly, means will be provided for closely regulating the temperature of any room at any desired temperature, both in summer and winter. An important departure in the construction of this building will be the fact that the basement, instead of being given up to heating, lighting, ventilating and power plants, will be utilized solely for the more precise 8 THE IRON AGE. July 17, 1902 work of the iaboratory. Four large rooms will be fitted up in the basement as special temperature rooms, and the entire underground story will be vaulted over so that both the basement and the floor above will be practically free from vibration. The second floor will be set aside for the administrative and clerical work, and for a li- brary and museum in which standards and apparatus of historical importance will be preserved. A well equipped chemical laboratory will be fitted up on the third floor, part of which will accommodate u laboratory for photometric research. There will also be provided on this floor a lecture room with a seating ca- pacity of 150 or 200. As it will be the policy of the bu- reau to keep in close touch with the interests it serves, it is hoped that it may soon be in a position to extend in- vitations to scientific and technical associations to hold their meetings from time to time in Washington. WwW. L. 0. ———$—_—_—_— Increasing Interest in Nrawback Regulations. WASHINGTON, D. C., July 15, 1902.—Drawback regu- lations have been prepared by the Treasury Department within the past week covering the exportation of hy- draulic jacks manufactured in part from imported seumless steel tubing and of horse nails manufactured wholly from imported Swedish steel nail rods. In this connection it is an interesting fact that the agitation of the subject of liberalizing the drawback laws has served to attract the attention of many manufacturers, not heretofore conversant with the law, to the fact that drawback is obtainable under the present statute under conditions that are quite practicable, with the result that the Treasury Department is in receipt of numerous applications from representatives of a variety of trades. As was recently indicated in these dispatches, the action of the Secretary of the Treasuryin approving the proposed liberalizing of the drawback laws, as outlined in the Lovering bill, has served to broaden the views of the experts of the customs division, and applications are being allowed as rapidly as the necessary investigations can be made where the special agents’ reports are found to be favorable. Hydraulic Jacks. The regulations for the allowance of drawback on the exportation of hydraulic jacks have been prepared upon the application of Philip S. Justice & Co. of Phila- delphia, who propose to import seamless steel tubing upon which a duty of 35 per cent. ad valorem is imposed, the drawback being equal to the total duty, less the legal deduction of 1 per cent. It is proposed that the draw- back entry shall show the marks and numbers of the shipping packages, the number and size of the jacks therein, and the number of pounds of tubing used in their manufacture, and, furthermore, that, in addition to the usual averments, the merchandise was manufac- tured in the manner set forth in the manufacturer’s sworn statement. The number of jacks exported shall be ascertained by the expert officer, and weights veri- fled by a United States Weigher. In the liquidation of the entries a sworn statement of the amount of imported tubing used in the manufacture of the 10, 15, 20 and 30- ton jacks must be filed with each entry, and as a basis of liquidation the amount of drawback allowed may be that declared in the drawback entry, but shall not ex- ceed 63 pounds in 30-ton jacks, 37 pounds in 20-ton jacks, 32 pounds in 15-ton jacks, and 21 pounds in 10-ton jacks. Horse Nails. The regulations for the allowance of drawback on horse nails manufactured from imported Swedish steel nail rods have been formulated upon the application of the Capewell Horse Nail Company of Hartford, Conn., the allowance to be equal to the duty paid on the rods less 1 per cent. ‘he preliminary entry is required to show the marks and numbers of the different shipping packages, their gross weight stated separately for each description of package, and the net weight of horse nails contained in each and in the entire shipment. The gross and net weight of each shipping package must be marked or stenciled thereon. The drawback entry must show the total net weight of horse nails exported and July 17, 1902 the weight of imported steel rods consumed in the manu- facture. The entry must further show, in addition to the usual averments, that the exported nails were manu- factured of materials and in the manner set forth in the manufacturer’s sworn statement. In liquidation the quantity of stee! nail rods in condition as imported, which may be taken as the basis for allowance of drawback, may equal the quantity consumed as declared in the drawback entry, but in no case shall it exceed the net weight of the exported nails, officially verified, with 12% per cent. of such weight added thereto to compensate for waste incurred in the manufacturing process.
