The Simonds Mfg. Company, maker of saws and ma chine knives. Seventeenth street and Western avenue, Chicago, Ill., has had in operation for some time an inter esting coal handling equipment. house is equipped with four 250 horse-power Babcock & Wilcox water tube boilers, furnishing steam to a 500 horse-power compound engine for general power supply and also to two heavy duty direct connected rolling mill engines for the crucible steel department. The plant is of an intermediate size ; hence it was a question whether The company’s power it would be more advantageous to put in an elaborate coal handling apparatus or to handle the coal and ashes New Ycrk, Thursday, July 13, 1905. The helicoid conveyor, which is behind the shields at the lower end of the boom and cannot be seen in the en- graving, is right hand pitch on one side of the center and left hand on the other, its rotary motion tending to de- liver the coal to the center, or in the path of the traveling elevator buckets. On the shaft carrying these helicoid conveyors are hardened steel pickers. These are simply short iron bars with pointed ends, which assist in break- ing up the coal, especially when it is frozen. The entire carriage has a longitudinal feed of 6 to 9 inches per min- ute when the device is elevating coal and 15 feet per minute when traveling idle from one car to another. Power is furnished by a 20 horse-power electric motor, taking its current from a simple two-wire trolley. The buckets are 12 inches long, 6 inches wide and 8 inches deep and are spaced 12 inches apart on the chain. There is said to be no difficulty in completely filling the Fig. 1.—Machine for Unloading Coal Cars at the by hand. In taking up the matter with different com- panies manufacturing conveyors and coal handling ap- paratus the total cost of an outfit for this plant was vari- ously estimated at from $9000 to $16000. Feeling that the saving in labor would not warrant this expenditure the apparatus herein described was designed, and so far has been satisfactory in every way. Fig. 1 shows the coal car unloading machine, which travels on an elevated track running parallel and some 20 feet above the railroad track. The boom, or that part carrying the bucket elevator, is suspended from this traveling carriage and is completely controlled and op erated by power. Fig. 2 shows the elevator at work and is taken from the rear of the boom. Fig. 3 is a detail view showing the lower part of the boom carrying the buckets, helicoid conveyor, pickers, &c¢. The principal points of interest are shown plainly in this view. The boom very nearly fills the space between the sides of an ordinary coal car and is kept from dragging on the bot- tom by guard wheels, which at all times keep the pickers, cleaning-up aprons, helicoid conveyor screws and other working parts about 1 inch from the bottom of the car. Simonds Mfg. Company's Plant, Chicago. II] buckets even thus closely spaced, as the helicoid con- veyor delivers the coal directly into the buckets instead of leaving the buckets to pick up the coal. A trough extends from the top of the carriage out over the storage bin, with suitable openings, which may be regulated so as to deliver the coal at any point cross- wise of the bin. The trough contains a helicoid conveyor driven by a chain from the main shaft of the machine, which receives the coal elevated by the buckets and dis- tributes it as desired in the bin. This is done very evenly, due to the longitudinal motion of the whole apparatus while at work. The numerous controlling levers, clutches, &¢., con- trolling and operating the different feeds, hoists, &c., have heen designed so that it is impossible to get two opposing motions in the gear at the same time. The elevator complete, including experimental work, has cost approximately $2000, and with labor at 17 cents an hour makes the average cost to deliver the coal from the car to a 22-foot level 1% cents per ton, or less than one-third the cost of unloading by hand. The average time in unloading a 30-ton car is 65 minutes, and the time getting from car to car from five to ten minutes, based on the distance the boom has to be raised, the length that has to be traveled to the next car and other conditions. One man operates and takes care of the ma- chine and easily cleans up what little spill there is left behind the buckets, keeping this always shoveled through to the front side of the aprons; so when the elevator has reached the end of the car the work is all completed, and there is no sweeping or cleaning up of any kind after the apparatus has been taken out of the car. A novel apparatus for handling the coal from the bin to the boilers is also used. This outfit consists of a tun- nel extending the whole length of the 110-foot bin and the length of the boiler house. The part extending into the boiler house is located immediately in front of the ash pits and 8 feet below the level of the main power house floor. At the end of the power house nearest the coal bin is located an hydraulic elevator, which is used to elevate cinders and also coal. The coal is taken through small sliding gates, located at intervals of 36 inches in the bottom of the bins, into small side dumping cars hold- ing approximately 600 pounds. These cars are pushed by hand on a narrow gauge railway to the hydraulic elevator and are carried to a level that allows them to be dumped 74 THE IRON AGE July 13, 1905 day of any coal that can be handled in bucket elevators an outfit of this kind is eminently suitable. The conveying and elevating machinery described was built and installed by the H. W. Caldwell & Son Company, Chicago, Ill. — --——-»-e—__-—___ An Important Trademark Decision. WASHINGTON, D. C., July 10, 1905.—A comprehensive decision of much importance to trademark owners has been rendered by the Commissioner of Patents and sus- tained by the Court of Appeals of the District of Colum- bia under the new trademark act, which took effect April 1. This decision determines an issue of far-reach- ing consequences, holding in effect that a large class of applications under the old law, which have been as- sumed to be still pending on appeal in the Patent Office, although adversely acted upon, cannot be further con- sidered under the new law, but must be treated as finally rejected under the former statute, and can only be re- vived by the filing of new applications under the pres- ent trademark law. Applicants whose cases come within the scope of this decision will be put to considerable expense, as they will be obliged to begin proceedings de Fig. 2.—An End View of the Coal Unloading Machine. directly into the hoppers of the automatic traveling grates which are used on these boilers. . The cinders are raked and shoveled into the cars and removed through that part of the tunnel located in front of the ash pits. The cars are elevated by the elevator used for the coal and are carried out over an elevated steel runway, which is on the same level but has no con- nection with the track from which coal is supplied to the hoppers over the grates. Compared with more elaborate equipments, which are without question more economical for larger plants than the apparatus just described, this system is elementary ; but the Simonds Mfg. Company found that none of them would save any more labor than the device described, and the repairs and upkeep have been merely nominal. The behavior of the apparatus in cold weather is stated to be especially satisfactory, no trouble having been experi- enced in two winters from frozen coal either in the cars or in the bins. It is not believed that a system of this kind would be suitable where the consumption would warrant more extensive conveying apparatus, but it would seem that for plants using from 50 to 75 tons per Fig. 3.—Nearer View of the Lower End of the Machine at Work. novo and again pay all fees provided by the statute. The rights of such trademark owners, however, are not prejudiced by the decision, but, on the contrary, it is probable that in many cases trademarks rejected under the old law will be found to be registrable under the new statute. Statement of Case, The case upon which the Commissioner and the court have ruled was that of a trademark owner whose application was rejected under the old trademark law of 1881, and who undertook to amend his original appli- eation so as to bring it within the scope of the new law, Section 14 of which provides “that an application for registration of a trademark pending at the date of the passage of this act, and on which certificate of regis- tration shall not have issued at such date, may at the option of the applicant be proceeded with and regis- tered under the provisions of this act without the pay- ment of further fee.” Section 24 of the act provides that “all applications for registration pending in the office of the Commissioner of Patents at the time of the passage of this act may be amended with a view to July 13, 1905 bringing them and the certificate issued upon such appli- cations under its provisions, and the prosecution of such applications may be proceeded with under the provisions of this act.” Relying upon the clauses above quoted, the applicant sought to bring his case under the provisions of the new law by filing an amendment, but the examiner refused to entertain it and also refused to consider the question whether the alleged trademark registrable under the new statute, holding that this was not a “ pending” case within the meaning of the law and that therefore the applicant was not entitled to amend it to bring it under the provisions of the new law. An appeal having been taken to the Commissioner of Patents, that officer ren- dered a decision sustaining the examiner on all points in an opinion from which the following extracts are taken: was Commiissioner’s Opinion, The sole question presented by this appeal is whether the applicant is entitled to amend the case under the provisions of the statute above quoted. This is more in the nature of a petition that the examiner be directed to enter the amendment and consider the case on its merits than an appeal from a deci- sion rendered. There has ‘been no decision upon the question whether the mark which was presented in this application would be registrable under the act of February 20, 1905, to the party who filed this application. The permission of the amendment seems to be a condition precedent to a considera- tion of and decision upon the case under the new law. Since the examiner has refused to permit the amendment and has refused to decide the case under the act of February 20, an appeal under that act does not seem to be the proper remedy. The case must be decided under the new law before there can be an.,appeal under that law It is undoubtedly true that final judgment was entered in this case long before the law of February 20, 1905, was passed. Such judgment was entered by the Examiner of Trademarks and was affirined by ime on January 2, 1903, as the final judgment ia this case. Neither the decision nor the act of 1881, which was in force until April 1, 1905, nor the Rules of Practice of this office gave the applicant authority to amend or take further ae- tion of any kind in the case. The case was, therefore, to all intents and purposes dead. Even if it could be held that the applicant was entitled~to revive the case by a petition for rehearing, it is very clear that he should have taken that action before the law under which it was filed expired. Ample notice was given of the date when the law would expire, and since the applicant permitted this case to remain as one finally settled urtii after the expiration of that time it is now too late to revive it for the purpose of bringing it under the new law. Could it have been the intention of Congress in the above quoted provisions of the act to set aside and nullify all adjudica- tions m trademark cases for the past 24 years? I think not. Judging the intention by the words of the act, it seems clear that such was not the intention, since the right of amendment was specificaiiy con‘ined to cases which were pending at the time of the passage of the act. In limiting the right to cases periding at a particular time Congress said by implication that there are cases which are not pending. If the applicant's con- tention was sustained it would follow that all cases filed since the passage of the uct of 1881 are pending and that word as used in the statute would have no significance. It is not to be presumed that this word of limitation was used without inten- tion or effect. It must be held that the Examiner of Trademarks was right in refusing to permit the amendment in this case and in refusing to consider and decide the case under the act of February 20, 1905. Since this case is not under the act of February 20, 1905, and no decision has been rendered as to the right to register the mark under that act, the present appeal cannot be regarded as properly taken under that act. The appeal is dismissed, Court Sustains Commissioner, An appeal having been taken from the Commissioner's decision to the Court of Appeals of the District of Colum- bia, an opinion has been handed down sustaining the Commissioner and holding that the rejection of the appli- cation under the old law finally disposed of it in default of a request within a reasonable length of time for a re- hearing and that the repeal of the act of 1881 closed the door for any further proceedings upon the original appli- cation. Several hundred cases now before the office will be finally rejected under this decision, but doubtless many of them will be revived by the filing of new applications in conformity with the provisions of the new trademark act. W. L. C. ———_>- The Ernst Wiener Company.—Ernst Wiener has severed his relations with the house of Arthur Koppel, with which he had been connected for 18 years, 8 of which were as manager of the New York office, and has opened offices at 68 Broad street, New York City, under THE IRON un AGE 7 the firm name of Ernst Wiener Company. The new company will make a specialty of railroads and railroad materials of both narrow and standard gauge for all industries. A special factory equipment with wholly mod- ern machinery has been built in Youngstown, Ohio, for the purpose of exclusively building the specialties of the new firm, so that it is in excellent condition to take care A large stock of rails, industrial track, Associated with of all business switches, cars, &c., will always be kept. Mr. Wiener in his new enterprise is Carl Koch, for many years chief engineer of Arthur Koppel, as well as the larger part of his former staff. The new company is now ready for business. ————_- oe —__—_- The Crane Company Jubilee. During the last week the Crane Company, Chicago, has been celebrating the fiftieth anniversary of the found- ing of the business. Fifty-five managers of branch houses with their families were called together from the Atlantic to the Pacific in Chicago, July 3, where they were domi- ciled at the Auditorium Annex at the company’s expense for several days. A banquet to these managers and to local department managers was given by Mr. Crane at the College Inn of the White City, Monday evening, and Tuesday morning the visitors went to Lake Geneva, Wis., as Mr. Crane’s guests, where they were entertained dur- ing July 4 and 5 at Mr. Crane’s summer home, Jersey- hurst. Features of the Lake Geneva jaunt were excur- sions on the lake on the host’s launch and a set dinner, at which addresses of a felicitous nature were given and a presentation to Mr. Crane by his guests of a bronze statue. On the evening of the 5th the party returned to Chi- cago, and on the following day participated in a grand picnic at Northwestern Park and the Des Plaines River, which was given by the company to all its employees, the works being completely closed down for this purpose. On this occasion 5500 employees, together with their families, aggregating fully 15,000 people, were entertained in vari- ous ways. The picnic was managed by committees of em- ployees, though the expenses were borne by the company. It required 18 ten-car trains to carry those of the pic- nickers who left the Chicago & Northwestern depot. R. T. Crane, the president of the company, delivered an address to his men in which he earnestly sought to overcome the increasing feeling of hostility held by em- ployees toward the employing class, showing the men that the interests of the two branches were mutual and interdependent. Many prizes were awarded. J. Domi- nick, who had the largest family present, consisting of himself, wife and eleven children, was presented with a silver tea set. The four employees longest in the service of the Crane company—Cornelius Haley, 42 years; Ed- ward Gregg, 40 years; John Quigley, 38 years; L. Pilking- ton, 38 years—were each given a gold watch, as were Pauline Leverenz, 24 years, and her sister, Hertha Lever- enz, 18 years, the two women longest in continuous service of the company. A canvass of the employees showed that there were 42 men present who had served the company continuously for 25 years or more. This means that about 6 per cent. of the number of employees who were with the firm in 1880 are still in its employ. In 1880 there were 700 employees, and now there are eight times as many. During the jubilee week a dinner was given to the out of town managers and to the managers of local de- partments, including shop superintendents and foremen, by Richard T. Crane, Jr., at the Auditorium. The business was founded by the present president as a small brass foundry in the corner of a lumber yard of Martin Ryerson, Mr. Crane’s uncle, and the first casting was made July 4, 1855. Officers of the Crane company are now: President, Richard T. Crane, Sr.; first vice- president, C. R. Crane; second vice-president, Richard T. Crane, Jr.; secretary, A. F. Bennett; treasurer, A. F. Gartz. The company is stated to be the largest manu- facturer in the world of valves and fittings, in addition to being a large factor in the manufacture and sale of special machinery, tools and supplies used in steam and hot water heating, water works supplies, gas fittings, &e. Soe ae i { } : } Ww 9 5 renee wees ee The Flather Quick Change Feed Lathe. The quick change feed engine lathe shown in Fig. 1 combines a number of interesting devices for procuring a wide range of feed and screw cutting, together with ac- curacy and facility of operation. The compactness of the arrangement of the gear box at the front of the head, an interior view of which is given in Fig. 2, and of the covered gearing at the head of the machine are noticeable. The slotted steel strip on the under side of the gear box, THE IRON AGE July 13, 1905 central position the feed screw is driven by the gears L O. By moving the lever to the right gear O moves clear of its gear L into the space R and the clutch teeth on gear O engage clutch teeth on gear N, affording a second series of speeds. When the lever is moved to the left the gear O engages gear P in a similar manner and a third speed is procured. As a result 54 changes are procured, cutting threads from 2 to 128 to the inch and giving feeds from 7 to 418 to the inch. To insure that the intermediate gear K always ei Y ee Fig. 1—A New Quick Change Feed Lathe, Built by Flather & Co., Nashua, N. H. in connection with a projection on the lever, makes it im- possible to strike any one of the gears of the cone ex- cepting that which corresponds with the slot and its hole for the locking pin on the lever. A distinguishing feature of the device is the sweep, which is made in box form, completely inclosing the train of gearing connecting the spindle with the gear box, protecting the gearing and also the workman from injury. The mechanism provides 54 different feeds and threads without removing any gear, but when it is desired to use a different thread or feed than those shown on the index plate a gear can be sub- stituted for that on the driving shaft, the sweep being made adjustable for this purpose. This lathe is manu- factured by Flather & Co., Incorporated, Nashua, N. H. Referring to Fig. 3, the head stock spindle is shown at A, and from it is the usual train of gears to the gear B mounted on the feed shaft. This gear meshes with gear C, which is keyed to the pinion D, the space between them being slightly greater than the width of the gear G. Gear C and pinion D rotate constantly on the stud E. The double sliding gear G and H is mounted on the stud F. When the sliding gear is pushed in the gears B, C and H are in train. When it is pulled out the gears B, C, D and G are in train. Thus two series of speeds are ob- tained, the ratio between them being 8 to 1. The gear G is always in mesh with the gear I on the driving shaft, which is double the width of gear G to make possi- ble the constant mesh. The gear I is changed when it is desired to cut special or odd threads not on the index. Teeth are cut on the driving shaft J, Fig. 4, thus form- ing the driving pinion. The usual tumbler gear and lever are used for procuring the changes of speed in the gear box, the intermediate gear K meshing with a series of cone gears, L L. Above the cone L is a shaft, M, upon which are mounted the three gears N, O and P. Gears N and P run loose on the shaft and O is splined to it. These gears are in mesh with three of the cone of gears which drive them at different speeds. On the hubs of N, O and P are clutch teeth, so that when the lever Q is in its comes into proper mesh without striking the corners of other gears of the cone there is fastened to the under side of the box a steel strip having slots, S, Fig. 3, corre- sponding to the several gears of the cone, and on the lever is a projection, T, Fig. 4, which when the lever is lowered to take the intermediate gear out of mesh with the cone moves out of the slot, allowing the lever to Fig. 2.—-Interior View of the Feed Gear Box. be moved longitudinally but preventing it from being raised until the projection is opposite a slot and the inter- mediate gear is in proper position to mesh with another gear on the cone. The general features of this lathe are those of the usual Flather type of machine. ———+-o>—___ It has been announced that the promoters of the tin plate factory at Morrisburg, Canada, have secured con- trol Sf the Canadian Tin Plate & Sheet Steel Company, 7; ye ~~ es July 13, 1905 THE IRON AGE 73 of the cable as the traveler crossed that Montreal and Toronto capitalists have become in teract the sagging terested and that the work will go on at Morrisburg. the chasm.

The air power plant at the terminal station of the Chicago & Northwestern Railway in Chicago is an ex- ample of modern practice in the application of electric power to the compressing of air for the many purposes characteristic of railroad yard work. The plant is lo- cated in a small brick building in the rear of the main terminal station, close to the river and adjacent to the extensive passenger yards of the company. This build- ing consists of two rooms, one containing the steam boil- ers for the heating system of the station and the other the electrical and pneumatic apparatus. Alternating current is taken from the city mains of the Chicago Edison Company and transformed to the working voltage, part being used directly on low voltage alternating circuits and the remainder converted to direct current for power purposes. The air compressor plant comprises two Ingersoll- Sergeant type JC power driven compressors. They are duplex two-stage machines, with air cylinders, frames and bearings, mounted on a solid cast iron bed plate which incloses the horizontal intercooler between the cylinders. Both high and low pressure cylinders are Fig. 1—View in the Compressor Plant of the Chicago & Northwestern Terminal, at Chicago, Ill. ground is perfectly level, well above high water and is ideal in every respect for manufacturing purposes. A town will be built upon the site, to be known as Midland. In addition to the manufacturing site at Cooks Ferry the company has purchased 900 acres of fine coal prop- erty located in the fourth pool of the Monongahela River. A large force of draftsmen has been at work for some weeks past on plans for coke ovens, blast furnace and steel plant, but at the present time those interested do not care to give out for publication just what finished products they will manufacture. He From data recently published in connection with the present tendency in American colleges toward engineer- ing as compared with arts it is found that, taking 18 of the leading institutions which offer courses in arts, sciences and engineering, the ratio of increase during the past four years in arts and science has been but 15 per cent., even though these courses include practically all of the women students. As against this increase is set that for engineering, which is no less than 102 per cent. The figures include only reguiar students and seem to form one of the signs of the times. fitted with the standard Ingersoll-Sergeant piston inlet valves, and regulation is secured by a choking controller on the low pressure intake. This device, acting to throt- tle the air intake passage, is controlled by receiver pres- sure and automatically regulates the volume of air com- pressed, and consequently the amount of power consumed, according to the demand for air from the power system. The compressors run at constant speed, the controller simply varying the effective piston displacement with varying load. The machines have a stroke of 12 inches, with air cylinders 1244 and 184 inches in diameter. At 130 revolutions per minute the free air capacity of each unit is 455 cubic feet per minute. The pressure used is 70 to 80 pounds gauge. The sub-base of each compressor is extended to sup- port the driving motors, which are General Electric di- rect current machines rated at 80 horse-power and 510 revolutions per minute on 220 volts. A pinion on the motor shaft gears directly with teeth on the compressor fly wheel, the gears being protected by guards. Inde- pendent concrete foundations are used. Each unit has its own automatic oiling system on all bearings, fed from a central tank. The drip is recovered and filtered. Sight feed oilers care for cylinder lubrication. July 13, 1905 Fig. 1 shows the arrangement of the air plant and Fig. 2 a side view of one of the sets. The machines are side by side, the switchboard, rheostats, meters, &c., being mounted in front of and between them. An intake duct supplying both compressors extends under the floor to the open air and rises beside the power house, terminat- ing in a screen cover to exclude dust and cinders. The discharge pipes from the two units combine in an air main leading to the primary receiver outside the plant. Provision is made for draining this receiver. From this point the line leads to a system of cooling tubes to the west of the power house, made up of a large upper and lower horizontal header, connected by a number of small vertical pipes. This apparatus freely exposed to the air precipitates whatever moisture may remain in the air after leaving the primary receiver, and this water is withdrawn from the lower header. From the cooler air lines radiate throughout the yard, supplying power to the pneumatic switch and signal system controlling the movement of trains in the terminal track system. Sec- ondary air receivers are also located at suitable places. Most of the air is used in this system of switches and signals, but a small portion is diverted to the boiler room, THE IRON AGE 79 to present stockholders, three-fifths in return for their present holdings and two-fifths for cash at par. oe —___ The Knoth Slag Process for Manufacturing Steel. On May 2, 1905, letters patent were issued to Henry Knoth, formerly superintendent of the steel plant of the Tennessee Coal, Iron & Railroad Company, at Ensley, Ala., and now superintendent of the Monterey steel plant at Monterey, Mexico, for a pvocess which has proved successful in increasing the output of steel while reduc- ing the cost of production. Mr. Knoth, who has given considerable study to the manufacture of basic gpen hearth steel, reached the conclusion that the present method of manufacturing steel could be greatly improved if a liquid basic slag could be provided at a minimum expense to start the heat quickly into action. When the molten slag is tapped from an open hearth steel furnace and thrown away there is a loss, not only of considerable basic materials but also of the heat in the slag. Ob- viously, if this heat and these basic properties can be successfully utilized in purifying other heats an economy Fig. 2.—Another View of One of the Motor Driven Compressors in the Chicago Terminal Plant. where it is applied in a small air lift pumping outfit which sapplies water to the terminal. —_—---o—_—_ The Arizona Copper Interests of Iron Men. By resolution of the directors of the Calumet & Ari- zona Mining Company the proposed consolidation of vari- ous copper mines in the Warren district of Arizona has been deferred. The conditions at some of the mines are such as to make it difficult to determine any proper basis for consolidation at this time, and probably for some time to come. This company has some 1700 stockholders, but the majority of its 200,000 shares is in the hands of very few, the estate of the late H. W. Oliver holding more than any other single interest. It was decided by the Board of Directors of the Calu- met & Pittsburgh Mining Company, an affiliated company, that the stock remaining in its treasury, amounting to 50,000 shares, par value $10, shall be issued at once at par to holders of the present stock, at the rate of one new share for every four now held, half to be paid August 1 and the balance in November. The company has been at enormous expense pumping water, and has incurred a debt of about $200,000; in addition to pumping from the depth of 1055 feet it is sinking two large shafts, one to go im- mediately some 50 feet more to the 1100-foot level and the other from the surface to 1000 feet. The directors of the Junction Development Company, another affiliated company, decided to reorganize into a mining corporation and to increase the stock from $750,- 000 to $3,000,000, of which all but $500,000 shall be issued E in manufacture will result. According to the Knoth slag process the liquid slag, resulting from an initial heat prepared in the usual manner in a basic open hearth furnace, is used continually to purify subsequent heats by being returned to the same furnace, unless it is stopped for considerable repairs, and in that event to any other furnace then ready for it. The losses in the basic properties of the slag by continually purifying heats are rgplaced by lime or other desirable fluxing materials. Preferably the unpurified metal to be acted upon by the molten slag is introduced into the furnace in a molten condition, or, better, is first blown in an acid converter. In both cases the reactions will at once set in in the bath, since the slag is in a ready condition. The duration of the heat is thereby considerably reduced. This process is being used at the Monterey steel plant, where it has uniformly given excellent results. Thus, 24 tons of pig iron (1.50 per cent. silicon, 30.40 per cent. manganese, 50.06 per cent. sulphur and 0.12 per cent. phosphorus) were melted with 6 tons of scrap without additions and tapped with 1 per cent. carbon into an open hearth furnace. The slag from a previous heat in this furnace was returned thereto in liquid condition with about 1000 kg. of limestone. The liquid slag im- mediately acted on the limestone, and after the addi- tion of some fluorspar the reaction began at once. After adding ore several times the heat was tapped in 2 hours and 35 minutes. This process was repeated a number of times with substantially similar results. Below are the analyses of the unpurified metal, the slag and the steel as tapped in three succeeding heats, the times for the heat being given: oa 80 THE IRON AGE Duration of the Heat from Charging of the Liquid Material Till Tapping.

These analyses are furnished by Franz Putsch, chief chemist of the Monterey Steel Company. The process will operate most successfully when the pig metal is treated in an acid converter, and it is clear from the results above obtained that where the unpuri- fied metal is blown in the converter to 1 per cent. earbon and then charged into an open hearth furnace and treated in accordance with the Knoth slag process a production of 200 tons of steel within 24 hours can be easily obtained from’ a 30-ton furnace. The Knoth process will be of considerable importance to Southern steel manufacturers. It is believed that the saving in basic materials largely offsets the cost of blow- ing the metal in a converter and would cheapen the duplex process, such as is now being successfully carried out at the Ensley steel plant. In addition to this the other ad- vantages of the process consist in the increase of pro- duction, the short time of the heats in the furnace and a correspondingly increased life of the furnace hearth, the opportunity to repair the furnace bottom between heats without interrupting the continuity of the process, the July 13, 1905 utilization of all the basic properties in the slag and the reduction of the quantity of material thrown on the slag pile and handled at an expense. —————-—- oe A Special V & O Geared Power Press. The machine illustrated in Fig. 1 is a No. 3 V & O in- clinable geared power press specially equipped for the rapid manufacture of disks of the form shown in Fig. 2 and known as roofing caps. The presses are made in a series of seven sizes, ranging in weight from 500 to 5500 pounds, and are so arranged that a great variety of automatic feeds and appliances for the economical pro- duction of sheet metal goods in various forms can be attached to them. The press illustrated is provided with a nest of 17 punches and dies, an automatic gauge, a set of double roll feeds and a positive knockout. It is designed to take 14 x 20 inch sheets of tin of any gauge and is capable of turning out roofing caps at the rate of 91,000 per hour. The sheets of tin are placed by the operator to an auto- matic gauge and are then carried through the dies and punches automatically by the double roll feed. The com- pleted caps are automatically ejected from the punches by the positive knockout. As constructed the press will admit various sizes of punches and dies.

July 13, 1905 Chain Making by Electric Welding. BY ANDRIS-JOCHAMS, BRUSSELS, BELGIUM. It is only recently that welding by electric current has been employed in chain manufacture. The process first secured recognition in Germany, France, Belgium, Russia, Italy and Sweden before it was experimented with in America. The process with which the present article deals was that evolved after years of experiment by Eugene Francois Giraud of Doulaincourt, France. Claims for the Giraud process are economy, rapidity and su- THE IRON AGE 81 at an angle of about 60 degrees with the diameter of the rod. This leaves the ends scarfed and separated about 14 inch, so that the chain may be assembled. The links are then taken to the welding fires. The furnace in which the chain is welded consists of a box about 31 inches long by 26 inches wide by 12 inches high, made up of cast iron plates bolted together and supported on legs. The box is lined with fire brick ex- cept in the center, where the air and gas mix. The top ox the box is of fire clay and contains 14 holes, each large enough to admit a link. Two workmen use one furnace, each having an anvil at opposite sides of the furnace. The anvil is grooved to hold a lower die, upon which the Chain periority of production. To contrast this new with the present manrer of producing chain a brief de- scription of the latter will first be given. process Present Manner of Making Chain on Gas Fires, In the present process the stock arrives at the plant in coils, which are placed on a reel and wound on a link winding machine into spirals. The link winder com- prises a short shaft about 4 feet long driven by a belt and pulley at one end and having a mandrel or link form- er at the other end. The mandrels are detachable pieces of cast steel shaped to conform with the inside of the re- quired link. ‘The end of the coiled rod being fastened around the mandrel and the winder started, the stock is wound closely into a tight spiral by the pressure of a grooved guide wheel, and when a spiral has been made about 6 feet long the stock is cut from the winder, the spiral is released and is taken to the link cutter to be cut into links, The link cutter is a power driven machine having two cutting blades, the lower one of which is stationary, while the upper one slides vertically between guides. The spiral is fed into the machine so that the cut is made A No. 3 Giraud Bending Machine, Capable of Automatically Cutting and Welding 20,000 Links of 9-32-Inch vu Per Day. link is welded. A hammer arm is hinged to the far side of the anvil and is manipulated by the foot of the work- man. The under face of the hammer is grooved to carry the mate to the die in the face of the anvil, and between these two dies the link is welded and finished. Gas at 8 ounces and air at 6 ounces pressure are forced into the center of the forge and ignited, the heat emerging through the holes in the top. Each chain maker has a helper who feeds the links to the machines. When a link has reached welding heat it is taken from the furnace, hooked through the last completed link and the ends closed together by a few light taps of a hand hammer. The link is then placed on the lower die; and finished with the foot power hammer, which com- pletes the weld and finishes off the surface. Defects of This Method, Obviously there is a great deal of heat wasted and from the manner in which the links are heated it is reasonable to expect a considerable number of imperfect welds. In point of fact, upon examination of a large number of links in a common chain welded in a gas forge there were less than half of the welds which were perfect. 82 THE IRON One of the main reasons for the imperfect welds is the way in which the link is scarfed. The thin part cools more rapidly than does the body of the scarf and loses its welding heat before the weld is made, with the result that the ends of the scarf are not welded, but merely pounded together. Tests of chains welded at the end of the link show that 75 per cent. or more break at th
