The Yeakley Vacuum Power Hammer. There are many so-called pneumatic hammers which are in reality merely air cushioned hammers. The Yeak- ley hammer is not of this class, but is a true pneumatic power hammer in the sense that it is operated by air, the process consisting of alternately expanding and com- pressing the air above the ram, so as to lift the ram by creating a vacuum and throw it down by pressure. It is a hammer that is admirably adapted for welding work, as it strikes a quick, hard blow on the first stroke. This is essential also for drop forging, as the first blow should A YEAKLEY VACUUM POWER fill the die to give sharp, clean results. Its ability to strike a true square blow and its large die surfaces make it suitable for a great variety of work usually done on drop hammers. On such work it has an ad- vantage over drop hammers, as it operates faster, hence it can perform more work in a given time. Another feature of the hammer is that it maintains the same speed on both light and heavy blows. It is very desirable to finish work with light, rapid blows, after first forging roughly to shape with heavy blows, but this cannot be done on most power hammers, as the speed slackens when the strength of the blow is decreased. It is stated that by careful test this hammer has been shown to consume no more power than other hammers in proportion to its size and the work accomplished. Recent improvements to the hammer have perfected it to a considerable degree, increasing its efficiency and decreasing the power de- manded. In construction the hammer is massive in all its parts. The anvil is turned and is particularly heavy. Its top is made with a steel tongue, which fits a recess in the steel shoe or lower die holder. A hard lead backing be- tween the frame and the anvil permits it to settle on its own foundation so that the dies will remain in align- ment. The ram is of steel, and is guided on all four sides in a rectangular chamber. The shaft runs in a long bronze bearing and is readily removable. The air cylinder is located on the back of the hammer, as may be seen in the illustration, and is single acting, being open at the lower end. The piston is driven by crank HAMMER OF 250-POUND SIZB. and connecting rod attached to a heavy balance wheel, after the manner of an ordinary steam engine. An air passage communicating with the cylinder above the pis- ton leads through a valve either to an expansion chamber in the center frame of the hammer or to the ram chamber. The controlling valve is operated by a foot tredle, as indi- cated. When the treadle is up the valve permits the air from the air cylinder to enter the expanding chamber, where it is alternately expanded and compressed while the hammer runs idly. This occasions little waste of power, due to the nearly perfect elasticity of air, hence whatever work is done in compressing it is returned when it expands. Any excess of air in the air chamber beyond that required escapes through a check valve. De- pressing the treadle rotates tue valve and gradually turns the pressure into the ram chamber, cutting it off from the expansion chamber. In this way a gradually accelerated motion is given to the ram from a light blow up to the owes GRA Mls 2 THE IRON AGE. heaviest. The ram is raised by the vacuum created in the ram chamber during the down stroke of the air pis- ton, and is thrown down again by the return stroke of the piston. It gains some additional force for its blow by an air cushion formed in the ram chamber after the ram passes and closes the air port, the latter for this reason being placed in the side of the chamber a little below the top. When the hammer is running idly the vacuum holds the ram suspended ready for the next blow. When the treadle is depressed to its lowest po- sition the ram will descend and remain down. This is useful when removing the upper die or tightening the key and also when it is desirable to hold the work be- tween the dies, as while twisting or bending it by hand, A very sharp, quick blow is obtained by depressing the treadle suddenly. When the hammer starts from rest the air for the first stroke is admitted to the ram cham- ber through a secondary passage leading from the valve to the top of the ram chamber, which has a check valve at its port, so that no air can escape from the ram cham- ber. The accompanying illustration shows a hammer of the 250-pound size, which is one of the most popular, as judged by the number of sales. It is also made in 40, 80, 150, 400 and 600 pound sizes. The 40-pound size has the anvil cast in one piece with the frame and the 80-pound is usually made the same way. If de- sired, it may be fitted with a detachable anvil, as are the larger sizes, as already described. The hammer has an interesting history. It was in- vented and patented several years ago by Wm. A. Yeak- ley, then residing at Cleveland, Ohio. One of the men associated with him at that time abstracted a set of the drawings and took them to England, where he sold them to a firm, who immediately built up a large business with the hammer. Subsequently, Mr. Yeakley sold his foreign patent interests to Wm. Graham & Sons of Lon- don. Between the two English firms, and a third firm who obtained the German rights, a great many hammers built on the Yeakley principle have been sold in Bngland and other foreign countries. The United States rights are owned by Willliams, White & Co., Moline, Ill. For some reason the hammer at first did not seem to take in this country, which may have been due to the fact that we use bulldozers, drop hammers and forging rolls and presses in many operations which are done on steam or power hammers in foreign countries. English manu- facturers are said to be more alive to the merits of a first-class power hammer than are the manufacturers in the United States, possibiy because the latter have had too many unpleasant experiences with hammers of a cheap class. It is noticeable now, however, that the sale of the hanmmer is steadily increasing here, and the re- ports of the results obtained are very favorable. The manufacturers of steel wagon and carriage axles were among the first to appreciate its value and are said to bave bought a great many. -———_s-e__— Signers of the Amalgamated Scale.—The following have signed the Amalgamated scale for the year ending June 30, 1905: Brown & Co., Incorporated, Pittsburgh, Pa.; Licking Rolling Mill Company, Covington, Ky.; Highland Rolling Mill Company, Terre Haute, Ind.; Griffiths Charcoal Iron Mill, Washington, Pa.; Hagle Horseshoe Company, South Milwaukee, Wis.; Railway Spring Company, Detroit, Mich.; Cleveland Hardware Company, Cleveland, Ohio; Kansas City Bolt & Nut Com- pany, Kansas City, Mo.; Fort Wayne Iron & Steel Com- pany, Fort Wayne, Ind.; Empire Iron & Steel Company, Niles, Ohio; N. & G.

A decision of the United States Circuit Court of Appeals for the third district was handed down at Phila- delphia on July 5 which is of interest to iron makers and metallurgists. The Davis-Colby Ore Roaster Company is the owner of a patent process for roasting and calcining iron and other ores by use of gaseous fuel, which process has been for some years in successful use in desulphurizing iron ores, or in roasting magnetic ores for rendering them porous, or in treating wet hematites for elimination of moisture and chemically combined water. As long ago as 1890-1891 several kilns adapted to this process were erected at the Colebrook furnaces at Lebanon, Pa. In 1894-1895, some important improyements in the process having been made, a proposal was presented by the Davis- Colby Company to the Lackawanna Iron & Steel Com- pany, who had in the meantime become owner of the Colebrook plant, for the erection and operation of a trial kiln at Lebanon. This kiln was built and put in opera- tion in 1895. When the trial run had been concluded an offer was made by the Davis-Colby Company for the con- struction of a battery of kilns at Scranton for the Lacka- wanna Company. This offer was declined by the Lacka- wanna Company, which proceeded, under the direction of its manager, Henry Wehrum, to erect from fits own de- signs a roasting kiln of capacity of 600 tons daily, at an admitted cost of over $100,000. This kiln was suc- cessfully and continuously operated until 1900, when it was taken down and the structural material utilized for the installation of a similar kiln at the Colebrook fur- naces at Lebanon, The Davis-Colby Company claimed that these two kilns embodied the essential features of its process, and in 1900 brought suit in the United States Circuit Court of the middle district of Pennsylvania, at Pittsburgh. The case was vigorously contested on both sides, with the aid of varied exhibits and models, and developed a very interesting mass of technical and expert testimony on the various phases of the operations of roasting and calcining ores. While the case was pending very large rectangular kilns of the same general character were installed at the Lebanon furnaces of G. Dawson Coleman and at the works of Joseph Wharton at Port Oram, N. J. Both these structures were erected by Frank Roberts & Co. of Philadelphia under their own plans, but licensed by the Davis-Colby Company. Several similar kilns have recently been constructed in England by Roberts & Co. under the name of “ Roberts kilns.” A decision in favor of the Davis-Colby Company was handed down in the Circuit Court in February, 1904, by Judge W. H. Archibald. An appeal was taken from the Circuit Court to the United States Court of Appeals, which was argued before the three judges at Philadel- phia in March last, and on July 5 a decision was handed down sustaining the decree of the lower court. An in- junction has been issued restrainnig the defendant from use of the kiln at Lebanon, or elsewhere, and a master has been appointed by the court to assess damages. The decision in this case assumes an added importance in view of the fact that many large iron and steel plants are installing at their works by-product coke ovens, from which enormous supplies of waste gases are available for roasting ores, thus rendering the cost of the roasting exceedingly small. At Port Oram, N. J., by suitable mechanical appli- ances for handling the ore and the use of waste gases from the blast furnace in the kilns, the cost of treating the ore is nominal, while the hard, dense Hibernia -mag- netic ores are rendered so porous by roasting that the consumption of fuel per ton of iron is materially de- creased and the output of the blast furnace decidedly increased. i f Fe Ce Ie Bae rv gy July 14, 1904 The New Bement Ten-Foot Planer with Pneu- matic Clutches. Among the machines exhibited at the St. Louis Exposi- tion by the Niles-Bement-Pond Company, 136-138 Liberty street, New York, mention of which was made in The Iron Age of June 30, is the Bement 10-foot planing machine illustrated herewith. Incidentally, it is notable for its size, but its particular interest lies in its use of specially constructed pneumatic clutches for reversing the table. The resort to friction clutches operated by compressed air was an outcome of the demand for more power and higher return speed than can be obtained by shifting belts, due to their limit in speed and width. Another striking feature of this machine is the development of individual motor drives and their application. The clutches, two in number, are mounted on the shaft THE IRON AGE. position is provided for reversing the table travel inde- pendently of the dogs, this handle being connected with the air valve. The planer is adapted to take work 10 feet wide or 10 feet high, the width between the uprights being 10 feet 2 inches, and the distance between the table and the cross rail when in highest position, the same. The table is of very heavy construction, 8 feet 8 inches wide and 30 feet long, exclusive of pans at each end. It runs on two V’s, each 12 inches wide, which present a wearing surface between bed and table of nearly 9000 square inches. The V’s are self lubricating by means of oil pockets and roll- ers placed at frequent intervals lengthwise of the bed. These pockets are connected so that oil poured into one is equally distributed to all. The table is driven by an accurately cut heavy pitched rack of 15-inch face. The rack is engaged by a large bull wheel within the bed. and is mounted with other gearing on a frame detachable THE BEMENT-MILES PLANER HAVING PNEUMATIC CLUTCHES. usually carrying the pulleys, and run in opposite direc- tions. One clutch gives the forward or cutting motion to the table, and is equipped with change gears to vary the cutting speed for different materials. The other clutch has a constant speed for returning the table, the device being arranged so that irrespective of the cutting speed the return is always the same. To the side of the bed is attached a small operating valve with a lever for con- trolling the clutches. It is tripped by dogs on the table in a manner similar to the ordinary belt shifting device, but of lighter construction. From the valve pipes lead to the rear end of the clutch shaft, where there is a gland and stuffing box connection for conveying the compressed air through the center of the shaft to the clutches. The machine was designed to have a return table speed of 80 feet per minute, but was tested in the shops before ship- ment to 100 feet per minute. The driving motor is of 50 horse-power, nominal size, mounted directly on the side of the housing, and is geared direct to the clutch shaft without intervening belts. The cutting speeds of the machine are variable by change gears from 18 to 36 feet per minute. By increasing the speed of the motor a proportionate increase in the cutting speeds and return movement up to any desired amount may be secured. A light and neat handle at the operator’s from the bed. The bed is a heavy cored casting, the sides being connected by cross girts spaced closely throughout its entire length. The uprights are 20 inches wide across their faces, and each carries a substantial side head having automatic ver- tical feeds. The tool slides have a 24-inch horizontal trav- el, and can be swiveled for angular work. For quickly traversing the side heads up and down the uprights there is an independent 3 horse-power motor mounted on the left side of the machine and connected by gearing with vertical screws in the uprights. At convenient position for operating are placed the switches for controlling this motor. The cross rail is 30 inches wide on the face, and carries two saddles made right and left hand for bring- ing the tools close together. ‘The vertical tool slides have 30-inch traverse, and can be swiveled to any angle. The tool aprons are outside gibbed with T-slots and tool clamps, and have automatic tool relief operated by a ver- tical feed splined shaft. 'The saddles have feeds in either direction across the rail, and the tool slides have vertica' feed in their saddles. The cross rail is of sufficient length to permit one saddle being traversed clear of the upright, and allows full traverse of the other saddle between the uprights for finishing work of maximum width. At the rear of the cross rail at the left end is a 3 horse-powe~ Lower er ww era rae a a8 i SA RO BI ae aed P a + cere =? - 7 bt eye eae oe ees 4 THE IRON AGE. motor connected by gearing to screws and the feed spline shaft in the rail to provide power traverse for the heads on the cross rail and power vertical traverse for the tool slides. By means of a lever and switches conveniently placed for controlling this motor the saddles can be traversed quickly on the rail and the tool slides vertical- ly in their saddles. For raising and lowering the cross rail a 5 horse-power motor is mounted on top of the ma- chine, which is geared directly with the screws in the up- rights. ee The Rust Water Tube Boiler. The two most important features of the Rust water tube boiler are that it contains no flat surfaces requiring staying and no curved tubes. It was first introduced at the Minnequa Steel works of the Colorado Fuel & Iron Company, at Pueblo, Col., and was designed by E. G. Rust, formerly chief engineer and superintendent of that company. To avoid curved tubes and still use drums, a compromise is effected by employing a modified form of drum on which the surface is cupped outward by punches to give a flat entering surface for each individual tube. Between the tubes the drum retains its cylindrical form, which ‘provides the necessary strength without resorting to stays. As may be seen in the accompanying line drawings, the boiler consists of two steam and water drums, twe mud drums and an auxiliary drum, each steam and wa- ter drum being placed directly above a mud drum, and connected with it by a bank of straight vertical tubes, and the two mud drums by a horizontal row of tubes. The auxiliary drum is placed above and between the mud drums, and is connected to a series of headers by a bank of straight vertical tubes. These headers are placed be- tween the steam and water drums, and are‘connected with them by short, straight tubes or nipples. Bach drum is fitted with a patent pressed tube sheet, which has already been described. The holes for the tubes forming the main banks are so spaced that the tubes are staggered—that is, the two inner rows come between the tubes of the out- side rows—thereby securing a more complete exposure to the hot gases, which to'reach the chimney are forced to completely surround and envelop the tubes. These tubes are spaced to leave room enough between those of the outside rows to remove the tubes of the inner rows, thus making it a simple operation to remove and replace any tube without interfering with any other tube or any of the brick work. After a defective tube has been re- moved from the bank it is passed out through doors placed in the side of the setting for that purpose. By the introduction of the auxiliary drum and cen- tral bank of tubes the space necessarily left between the main banks of tubes is so utilized as to secure a serviceable and convenient support for the baffle wall, the tiles forming which are placed between and supported by the rows of tubes forming this bank, and, owing to the consequent increased heating surface, a boiler of larger capacity results without additional floor space, fittings or cost of setting. The boilers are made right and left hand, and are arranged to be set singly or in batteries of two. Each drum is provided with a manhole in one end to permit access to the interior of the drum, and in the top of each header there is a hand hole through which to reach the interior of the tubes of the central bank. The steam spaces of the steam drums are con- nected by cross pipes of liberal dimensions. On top of each is an outlet, on which is placed a nickel seated safety valve. The steam outlet is placed on top of and at the center of the rear steam and water drums. The boiler is supported by four large cast iron saddles resting on masonry foundations, one saddle being placed under each end of each mud drum. The saddles under one of the drums are placed on rollers to allow for expansion. By referring to the sectional view of the boiler, it will be observed that the top of the central baffle wall is far enough below the headers to leave sufficient space for the products of combustion to pass from the front to the back bank of tubes. It will also be observed that there are horizontal baffles or bracket tiles which project from this central baffle wall, and which serve to deflect July 14, 1904 the current of hot gases so as to force them toward and between the tubes of the main banks. The setting does not require any special shapes of brick, is symmetrical and durable, and is firmly bound together by buckstays, rods and angle binders at the corners, At the top of the setting and bolted to the corner binders is placed a box shaped frame, made up of channels and plates, which furnishes a rigid support for the breeching and stack, and also serves to bind firmly the brick work at the top of the setting. On one side of the setting, near the top, are placed four small doors which furnish access to the interior of the brick work and through which the tubes are passed in and out when replacements become neces- sary. Doors with small self closing openings through which to insert a hose for blowing. off the top of the tube sheets are placed near the bottom of the setting, and other doors are furnished for securing access to the in- terior of the setting and for blowing deposits from the exterior of tubes, Over each steam and water drum, and a little above it, is placed a light steel arch, which serves as a center to support the brick arches over the drum during con- struction and makes an air tight covering for the setting. These arches are placed sufficiently above the drums to permit upward expansion of the boiler without inter- fering with the brick covering. Between the two arches Fig. 1.—The Drum Containing the Pressed Tube Sheet. are placed doors through which access is given to the headers. Other very desirable features of the setting are its ready adaptability to an underground flue connection without the use of any pipe or plate work and its adaptability for the use of waste gases from a blast furnace and heating or puddling furnaces. The furnace is of the exterior type and is of ample capacity, allowing proper admixture of air and fuel and complete combus- tion before the gases reach the cooling influence of the heating surfaces. The brick arch also retains sufficient heat to tend to preserve a uniform temperature in the furnace. This type of furnace permits the ready ad- justment of grate area to suit any kind of fuel and the application of any style of grate bar or stoker. ‘The ratio of heating surface to grate area is such as to give the best results under average conditions, but may readily be proportioned to suit the kind of fuel to be used. As indicated by the arrows in the sectional cut, the flue ways are long, allowing ample time of contact be- tween the hot gases and the heating surface, so as to absorb the maximum amount of heat, resulting in low chimney temperature and high efficiency. Other de- sirable features of the construction are that the bottoms of the drums are not exposed to the action of the hottest flames, avoiding bagging and burning out of the sheets and the consequent danger of disastrous explosions, also insuring freedom from the destroying and weakening effects of corrosion, as the lower drums are not built up close with the brick work of the setting, and space is left for free circulation of heated gases when the boiler is in operation and of air when not in use. The rapid water circulation that is provided for, especially due to the vertical position of the tubes, has three resulting benefits—namely, a faster rate of evaporation, a more uniform temperature of water and boiler structure, pre- venting unequal expansion and contraction, and a tend- he § July 14, 1904 THE ency to lessen the amount of scale deposited on the in- terior of the heating surfaces. : The front is of cast iron of ornamental design, sur- mounted with a bracket in the center for supporting the steam gauge, and is so arranged as to permit the ap- plication of gas burners or any form of stoker. The Rust boiler has been in successful operation since the spring of 1902, during which time it is claimed to have shown excellent performance. Using Western coal which contains a high percentage of volatile matter and moisture, a boiler rated at 200 horse-power has developed on test over 400 horse-power in evaporation, furnishing dry steam and showing a boiler efficiency of over 67 per cent. and an average temperature of escaping gases of only 545 degrees F. The same boiler on another test, running slightly over its rated capacity, employing an inexperienced fireman and using low grade Western bitu- To Fig. minous coal, evaporated 10.4 pounds of water per pound of combustible and maintained a boiler efficiency of over 70 per cent. —_—_—- — He Oo —___-- The N. & G. Taylor Company’s Improvements.— The electrical appliances and other modern mechanical devices recently installed at the N. & G. Taylor Com- pany’s works at Cumberland, Md., have effected much economy both in time and labor. In the open hearth department of the plant the heavy ingots from the fur- naces are handled automatically throughout. Powerful overhead electric traveling cranes serve the open hearth and bar mill buildings, and auxiliary jib cranes cover an extensive radius of action for the lighter classes of work. In the bar mill department the continuous automatic ingot heating furnaces are fitted with the latest electrical charging and discharging machines. The regenerative principle has also been applied to these furnaces to util- ize the waste heat of the escaping gases. A special type of roller table is used to convey the long bars to the motor driven shears, the finished product being loaded automatically on cars by Link Belt conveyors, also espe- cially designed for the purpose.

An unusual organization was formed June 27, when 35 of the former employees of Corliss & Nightingale and the Corliss Steam Engine Company met at Providence, R. I., to form a veterans’ association. The youngest man in the party was 54 years old, the oldest 90 years. They began their connection with the famous steam engine builders all the way from 1844 to 1865. The meeting was at the Pomham Club, the trip being made by special steamer, and a dinner was served at which the feature was the presentation to each guest of a photograph of the late George H. Corliss by Mrs. Corliss and Miss Martha L. Corliss. After dinner the association was —__—~ THE {RON AGE ‘ 2.—Sectional Elevations of the Rust Water Tube Boiler. formed as the Veteran Employees’ Association of the Corliss & Nightingale and Corliss Steam Engine Com- pany.

This machine was not at first intended for the market, but was made to fill the require- ments of the company’s shops for a tool of tbis class, which would overcome the many defects and weaknesses mentee i a ee IRON AGE.

The pioneer ma- chine, however, demonstrated its value to such an extent as to suggest a field for its use outside of the home shops, and a number have already been manufactured and placed in‘ stock. In this machine the double spindle feature has been omitted because it was found that no matter how care- ful the operator might be, the constant swinging of the head back and forth against the stops caused their sur- tool steel, hardened and ground, and are aligned from a bar placed in the spindle of machine. Care in alignment is taken to enable the machine to accurately center stock for finishing purposes after coming from a turret lathe or screw machine. This was one of the important re- quirements of a centering machine as found in the every day work of the shops. It is to be noted that the block and vise operate in unison, controlled from the one ball handle, the two being kept in proper relation by means Twe 1ROn AGE Fig. 2.—Rear View. faces to wear, necessitating adjusting frequently to main- tain the spindle alignment. This same changing and alternate motion of the spindles in centering sooner or later resulted in their being driven into the hardened jaws of the vise, disfiguring the jaws and breaking the drills and reamers. Moreover, in the older machines, the spindles were necessarily very small in diameter, and the bearings wore out frequently, requiring the replac- ing of bushings every few months to keep the machines in serviceable condition. These defects have been over- come by using a rigid head with permanently aligned of the rod and spiral geared drive located at the back of the machine. This provides that any diameter of bar within the limits of the machine will always be sup- ported in a horizontal position, without the occasion of hand adjustment or “eye alignment” for back support as is usually required. The inclined surface of bed, sloping away from operator, tends to direct the chips into the pan, avoiding their accumulating around the head and the necessity of cleaning frequently when it is desired to shift*the carriage or saddle. The heavy parallel bars running the length of machine serve as a rack for carry-— July 14, 1904 ing stock to be centered, and prevent the common use of the bed as a temporary support for the stock, and consequent bruising and banging of the bed, which often throws the rear supporting block out of alignment. The saddles are gibbed and fitted to bed and provided with binding handles for clamping in position.

As an exhibit typical of the district, Pittsburgh has erected in the center of the Mines and Metallurgy Build- ing at the St. Louis World’s Fair a pagoda constructed of the finest specimens of steel rails produced within its confines. The exhibit was constructed under the direction of the Pittsburgh Chamber of Commerce and will appear with a relief map of Pittsburgh. The use of the steel rails was first suggested to the Chamber of Commerce by Dr. J. A. Holmes, superintendent of the Mines and Metallurgy section of the fair, who also had much to do with furthering the idea of the relief map exhibit. The rails will be erected in the shape of a huge pipe organ, and the word “ Pittsburgh ” in electric lights will extend across the sides of the pagoda. The rail exhibit was constructed at the shops of W. N. Kratzer & Co.. Pitts- burgh, at the expense of the Chamber of Commerce, and the cost of shipping and erecting was borne by the World’s Fair. iver since the World’s Fair began to attract large numbers of visitors the St. Louis Transit Company, which operates the larger part of the street car system in St. Louis, has been embarrassed for want of power. The plant has been working at an almost constant 50 per cent. overload, while at rush hours the excess has been extreme. The railway company recently applied to the World’s Fair authorities for additional power, with the result that Governor Francis and the fair ad- ministration have contracted to put at its service during the period of heaviest load, from 2 p. m. until 7 p. m., the huge Allis-Chalmers engine in the Machinery Build- ing. This engine, coupled to a Bullock electric generator, runs at 75 revolutions per minute, under a steam pres- sure of 150 pounds, and, operating noncondensing, is capable of developing 8000 horse-power. From 8 p. m. until the Fair Grounds close this power’ul unit supplies the current for the decorative lighting of the buildings and grounds, which make use of some 200,000 incan- descent lamps. The traction load which the engine and generator will carry will be at least 3000 horse-power, to begin with, and may be much increased as the World’s Fair crowds are augmented. This engine has won for itself the popular name of “ the big reliable.” The working model concentrating plant, built by the Allis-Chalmers Company, which forms one of the most interesting features of the State of Utah exhibit in the Mines and Metallurgy Building, is to be presented to the Utah School of Mines after the close of the Exposi- tion. Every separate part of the plant has been lettered with descriptive legends, so that the onlooker, as he watches the plant at work, will be able not only to see what is being done, but will also be able to learn the name of the part that does the work. This makes the plant much more interesting as an exhibit, and will add greatly to its value as an adjunct to the Utah School of Mines. ———~)-o———_———_ Addition to the Carnegie Institute at Pittsburgh.— The William Miller & Sons Company, Pittsburgk, has been awarded the contract for the addition to the Car- negie Institute, their bid of $2,591,993 having been ac- cepted. This is the largest building contract ever awarded any one company in Pittsburgh, and under its terms the work is to be completed on February 1, 1906. It was hoped that the new addition could be completed in time for Founder’s Day Exercises in November, 1905, but this proved to be impossible. The William Miller & Sons Company will be aided in the erection of the structure by 18 subcontractors, and at times work will be in progress day and night. It is estimated that fully 1000 men will be employed from the time the work is actively started. The building will contain 5560 tons of steel, all of which will be furnished by the Carnegie Steel Company. The contract awarded does not include the plumbing and elec- tric work, which will be given out later. 8 THE IRON AGE. A New Philippine Tariff. War Department Planning Reductions in Certain Schedules. WASHINGTON, D. C., July 12, 1904-—A strong move- ment is now on foot to bring about the material modifica- tion of the present tariff on goods imported into the Philippines, the speciai object being the reduction of the rates of duty on machinery of all kinds, material for the construction of railroads and numerous metal products designed for repair work or as materials for manufac- ture. So much progress has already been made that it now seems probable that the matter will be brought to the attention of Congress immediately after its meeting in December. and, as the strong influence of the Adminis- tration will be exerted to secure early action, it is possi- ble that the revised schedules may go into force soon after the beginning of the new year. Special Commission Appointed. The projected revision of the Philippine tariff was set on foot last fall by Secretary Taft, then Civil Governor of the islands, who appointed a special commission for the purpose composed of six members as follows: Acting Col- lector of Customs, H. B. McCoy; Deputy Collectors Pul- liam and Stanley of the port of Manila; Francisco Reyes, a native Filipino and president of the Manila Chamber of Commerce; M. F. Lowenstein, resident representative of a number of American commercial houses, and Frank L. Strong, an American engineer and contractor. The commission gave extended hearings at Manila, and re- ceived many suggestions from the representatives of va- rious interests, but few business men in the United States were aware of the work in progress, and until quite re- cently the War Department authorities had received lit- tle or no information concerning it. In undertaking the work of revision, the commission had in mind three considerations which were assumed to be in line with the policy of the American administra- tion: 1, The desirability of stimulating manufactures of all kinds in the Philippines by reducing the duties on ma- chinery, partly manufactured metal products and other materials; 2, the prospect of free trade with the United States at no distant date, an event that would make it necessary to dispense with the great bulk of customs du- ties; and, 3, the understanding that the Philippine Com- mission in the course of a few months would enact an in- ternal revenue law that would produce $7,000,000 to $8,000,000 of revenue to supplement reduced customs col- lections. Acting upon this general understanding, the Tariff Commission proceeded to cut nearly all the sched- ules very freely and to transfer numerous important items to the free list. While this work was in progress, Secretary Taft, who had assumed the war portfolio, undertook to ascertain the feeling in Congress with respect to the free admission of Philippine products into the United States, and the outlook for the ultimate abolition of all tariff barriers be- tween this country and the archipelago. The result was not at all encouraging to the secretary, and, as will be remembered, the House of Representatives declined to take any action on the bill urged by the Administration admitting free of duty all Philippine products except sugar and tobacco, which were to be charged with 50 per cent. of the Dingley rates. The Commission’s Report. When the Tariff Commission’s report finally reached the War Department, therefore, it was found that exist- ing conditions would not justify the very heavy re- ductions provided for in the revision and it was therefore decided to return all the documents to Manila for the examination of Collector Schuster, who was absent from the islands when the Commission’s report was made up. Mr. Schuster was instructed to examine the draft very carefully and to strike out all amendments except such as were expressly designed to remove inequalities in the tariff as developed by the experience of the past two and a half years and such as were intended to simulate manufacturing and railroad building in the islands. Acting under these instructions, it is expected July 14, 1904 that the present rates on machinery of all kinds, which average about 20 per cent., will be reduced at least one- half and that the duty on implements and machines employed either directly in agriculture or in the manu- facture of agricultural products will be fixed at about 5 per cent. The necessity for admitting machinery into the islands at the lowest possible rates of duty is set forth very urgently in a memorandum prepared by Mr. Strong, a member of the Tariff Commission, in part as follows: The supreme importance of lower duties on our exports has doubtless been the cause of neglect in urging changes of the duties on certain importations into the Philippines. Until re- cently no voice has been raised against the tariff upon importa- tions, the local press has been silent and duties unknown in any country in the civilized and even the semi-civilized world have been paid without public protest. Tariffs exist for a twofold purpose: First, for the raising of the necessary revenue required by the Government, and, sec- ond, for the protection of home industries. As practically no manufacturing industries exist in the Philippines, the latter cause does not obtain, and the most difficult factor in the prob- lem as known in the United States is eliminated. Considering, then, the question of revenue, it is granted that no form of taxation is so easily and cheerfully borne gs reason- able duties placed upon the commodities of common use. Mar- ket prices become established, and the consumer, who in the end pays the duty, gives no thought to the small added incre- ment he is unconsciously paying his Government with which to provide him with the blessings of civilization in a well ordered community. Such is the ideal tariff for revenue. When, how- ever, such duties become so onerous as to cripple established enterprises and prevent the formation of new ones, the very ob- ject which gave them birth is thwarted. It will be granted by all that manufacturing industries are needed in the Philippines. Raw materials of the highest grade abound. With few exceptions either hand labor or the crudest machines of centuries ago prepare such articles as are not im- ported. Money flows in a steady stream abroad for the purchase of the commonest commodities that could easily be made here. It would seem to be within the wisdom of the most dense mind that the importation of machinery should be encouraged, unless some satisfactory reason could be given why these islands should indefinitely remain as Magellan found them. Earnest efforts have been made to induce capital to invest in manufacturing enterprises in the Philippines. Let us state in plain language what the invitation carries with it. A modest manufacturing plant can be equipped with an outlay of $50,000 for machinery. Let us say distinctly to the man considering our invitation, that before he can receive his machinery from the custom house. the Government that invited him to come here and help develop these islands will demand a fine of $10,000, known as duties. A fine of $10,000 would be a heavy one for a criminal. Is it as such that we welcome the man whom we have invited to assist in developing the great natural resources of this country; to give employment to labor and to add to our revenues for years to come? China, Japan and other Asiatic countries welcome American machinery with a duty of but 5 per cent. Siam demands but 4 per cent. The Philippines, the particular ward of the United States, whose manufacturers hav
