wr wu ESTABLIS! 18 BY F. L. The general tendency in the building of automo- Hes is to reduce the weight wherever possible with- t impairing the strength, and this has led some akers to substitute sheet metal stampings for cast on for various parts. In addition to reducing the sight there are other advantages claimed for these rts such as the elimination of machine work and he shipment and handling of parts without break- ve. This substitution of sheet-metal stampings s necessitated some difficult and very interesting awing operations. One very difficult stamping is muffler head for the halmers automobile, the anufacture of which as recently undertaken y the Acklin Stamping ompany, Toledo, Ohio. This stamping re- uires ten operations ich are shown in the companying illustra- on. The first operation done on a simple com- nation die that cuts he blank and draws it bwn as shown in the pper left corner at 1. e die used for this peration is of the andard type operating n spring rubbers in the a of the press. The st reduction, which is landard type, operating spring rubbers in the i of the press, is shown at 2. This operation is tely to reduce the diameter of the shell from the st operation and at the same time to leave a small ge on the outside. At 3 is shown the cup turned inside out. The Used for this operation is also of the standard pe.

The trimming is done in a standard die which is provided with a pad in the lower die to locate and eject the work. At 7 the piece is seen finished apparently to size and shape. The outer flange in this operation is edged and struck to proper taper, the main body is struck and sized all over and the portion connecting the body to the flange is formed to the proper taper and smoothed out. Oper ation No. 8 is the punching of holes on the outer flange through which to rivet the body and the head of the muffler together The ninth operation which is also shown in the same view as the previous one is the punching of the hole in the side of the center body. This hole is punched in the die which goes on a horn pre The die itself is reversed the ordinary posi tion, the punch being placed below and the die above. This method is adopted for the reason that it would be impos sible in the limited space to provide a passage through the horn for the slug which comes out of the hole, and also for the done on a die of a Successive Stages in the Stamping of an Automobile Muffler reason that it is easier Head from Sheet Metal to gage the stamping with the die arranged in this manner than in the regular way. In the lower right corner the muffler head in its finished shape is illustrated. The finishing opera- tion of drawing the flange is the most difficult one, it being made so by the fact that it is impossible to get a die of any regular construction to do the work. The peculiar difficulty is that it is necessary to have the punch on the inside of the piece and to force the shell down around the punch. It is impossible to obtain more than about 40 per cent bearing surface for the upper die on the shell and this is not suffi- cient to do the flanging work, unless the stamping is firmly fastened so as to prevent it from skidding when the operation is performed. As the flange is turned up on an angle with the central axis and as 972 the stamping itself must slide along the axis of the hole a complicated arrangement of sliding gages and supports is necessitated. The horn that is used in this operation is identical in design with the one used in the previous operation, the horn fitting in the same press, the variation being only in the gag- ing and in the upper die. The muffler head is made from hot rolled pickled strip steel 0.078 in. in thickness. The shell is an- nealed only once, between operations 6 and 7. The principal breakage comes in operation 7 which is the finishing of the shell to shape, this being caused by the fact that the metal used varies somewhat both in thickness and in drawing qualities, so that the amount of metal that is gathered in this opera- tion also varies in cubic volume even though the surface is the same. When an attempt is made to draw the stamping to a perfect shape it is found that some of the pieces do not have sufficient stock and therefore crack, and some have too much stock and for that reason wrinkle. However, the loss due to breakage resulting from the varying thickness of metal is said to be quite small. Wide Face Ring Wheel Grinding Machine An improved flat surface grinding machine has been placed on the market by Charles H. Besly & Co., Chicago, Ill. -In general construction, the machine is the same as the builders’ single-spindle lever feed disk grinding machine except that one end of the spindle is equipped with a pressed steel chuck holding a wide face vitrified ring wheel for roughing off scale and excess stock. In this way it is possible for the work to float on the face of the wheel which has a grinding surface from 8 to 10 in. wide. The opposite end of the spindle is equipped with the ordinary steel disk wheel set up with cloth back abrasive disks for finish grind- ing. The body of the chuck is of pressed steel and is double rivet- ed to a cast-iron center into which the spindle bearing pro- jects. The chuck body is drilled and tapped from the back to re- ceive headless threaded plugs for balancing, and the grinding wheel is held in the chuck by pressure on its periphery applied by a wrought steel tapered clamp ring. This ring is drawn into the tapered chuck body by screws operated from the back of the chuck body. The center hole of the grinding wheel is filled with a steel plate, which is relied upon to guard the heads of the screws holding the chuck on the spin- dle, thus doing away with ex- ternal projections. As the grind- ing wheel wears away a laminat- ed wood plate which is supplied with the chuck may be employed to set out the wheel. This machine is designed to handle flat surfacing work that is now being done on milling and planing machines and the ac- bile companying illustration shows the grinding of automobile gear shifter covers. These are of malleable iron, are rather frail and are ground without rigid chucking. In this way, it THE IRON Performing 200 Rough and Finished Grinding Operations per Ho ; “ Gear Shifter Covers on a Wide Face Ring Wheel Grin , AGE Octo} s, 19}5 is pointed out, the danger of distortio ent where castings of this nature muy for milling is eliminated.

The he. tom of these blocks, which are of cast iron, mess. ures 6 x 13 in. and was formerly surfaced op ; adjustable-speed, motor-driven shaping machine using high speed tools. With a view to making this piece suitable for grinding instead of shaping, the pattern was changed, very little stock being left fg finishing while the surface was recessed in molding to facilitate grinding. The maximum amount stock which the grinding wheel has to remove : finish the piece is only 1/16 in. The time former! required for handling the work on the shaping ma. chine was approximately 20 min., while on the grinding machine these surfaces are roughed and finished to the proper size and shape in less thay 2 min., including a test on the surface plate. This machine is built in two sizes, one mounting a wheel 24 in. in diameter with an 8-in. hole, while the other has a grinding wheel 30 in. in diameter with a 10-in. hole. The wheels are 3 in. thick when new and can be worn down to 1 in. tH) fy shod ms Mac? al The Cleveland Blow Pipe & Mfg.

THE IRON oO =! wo AGE Adjustable Sheet Metal Guard for Belts C. C. Paeschke in February, 1914, applied for a patent on a belt guard that is in use throughout the plant of the Geuder, Paeschke & Frey Compan) Milwaukee, Wis. The claims have been allowed, but instead of manufacturing and the device, Mr. Paeschke has decided to grant the privilege of making these guards free of charge to any manu facturer who desires to put them in own plant. The special feature of the that provision has been made for readily and replacing the belts as well as the that is provided for adapting the guard machines, the driving pulleys of which are at varying distances from the floor.

To adapt the guard to varying conditions and to sustain it in working position at different angles corresponding with the varying inclination of the belts to which it may be applied, the fender has a series of hooks or catches on the under side for engagement with the cross piece of the U-shaped rod or bail. Another arrangement for supporting the fender entirely by the post or stand to which it is hinged or pivoted is shown in the lower portion of the accompanying drawing. In this form of guard the post or stand to which the fender is hinged or pivoted, consists of a metal channel bar with the web and flanges turned at the lower end to form a base. The upper portions of the flanges of the channel are formed with a series of notches into which the cross piece of the U-shaped brace or supporting rod drops. For replacing the belt the brace is disengaged from the notches in the post or stand and the fender swung back on the hinge. The sides of the fender in either form of guard cover the edges of the lower side of the belt, thus preventing a person from coming in contact with it and being injured.

A number of machines designed for automatic or semi-automatic operations in the com- pletion of small screw machine parts with a view to securing accuracy, maximum production and minimum labor costs, have been brought out by the National-Acme Mfg. Company, Cleveland, Ohio. One of these is a stud threading machine known as the No. 1, which is a high-speed automatic machine designed particularly for the rapid thread- ing of milled studs. An interesting feature of the machine is the method of feeding and extracting the work. Ordinarily, in stud threading work the piece is fed into the machine and is extracted when the die recedes by being pushed out by the piece that follows. In this machine the pieces are dropped into a horizontal magazine from which they are fed through a receiving tube by a push rod. When the die is opened, the jaws holding the threaded piece recede, allowing the piece to drop out instead of requiring it to be extracted. As soon as the threaded piece drops out, a new piece is fed up to the stop. As extracting and feeding are practically simultaneous operations, no time is lost in forcing the piece out and then oscillating Stud Threading Machine for Sizes up to % In. in Diameter in Which the Pieces Are Fed from Horizontal Magazine through a Receiving Tube by a Push Rod and the Finished Stud Drops Out of the Die, with a View of the Feeding Mech- anism Above THE IRON AGE Octob: 8, 1915 y y Z y L 4 Y Y SS x | ik Machine for Threading 1-In.

It weighs approximately in. in diameter. are the same as 875 Ib. A new tool grinding machine has been brought out which is designed primarily for grinding the faces and throats of die chasers. It is also adapted for grinding circular forming tools, blade tools, reamers and for miscellaneous tool grinding. An important feature of this machine is the work bed which consists of three slides, providing a wide range of adjustment in three directions and at the same time a rigid support for the work while it is being ground. The machine is provided with a loose pulley so that the grinder can be belted to either the main shaft or to a countershaft. The drive is through a two-step pulley at the top and bottom of the upright column. This provides variable grinding speeds and compensates for the wear on the grinding wheel when necessary. The top shaft bearings are hardened, ground and run in phosphor bronze bushings that are adjustable for wear. Special fixtures for holding the work are mounted on the work bed by key-bolts.

Some particulars regarding the school wer contributed to the recent meeting of the Lake Superior Mining Institute by C. S. Stevenson, Ishpeming, Mich, director of the educational department of the company From these the following notes have been taken: — The prime function of the school is to train to the highest possible degree of efficiency the English speak. ing men upon whom this inexperienced foreign produc depends for its guidance. The school, therefore, is no open to all underground employees of the company, but concerns itself only with a group of men who are carefully selected by the superintendents and mining captains on a basis of their ability and mining aptitude In the beginning it was noted that the men wer as a rule indifferent, if not antagonistic. Gradually, but not without difficulty, prejudices were broken down partly by the statement that in so far as possible all men chosen for shift bosses will be taken from the ranks of the mining school. On June 1, 1915, the work of the first class, comprising thirty-three men, was completed. The work of a single class is designed to cover 14 years. Each miner attends two classes a week, each of an hour and a half. If the miner is working on the day shift he attends the evening classes and if he is working on the night shift he attends the afternoo sessions. All of the class work is done on the miner? own time and they receive no remuneration from the company for that given to the school work. The mining school began its first class with a enrollment of thirty-eight men, and of these thirty: three successfully completed the work. Four of the five men, who did not complete the course, withdrew on account of business conditions, which made their attendance impossible. The men are not children but of mature years and respected in the communities which they live, and great care is taken not to wound their pride and self-respect. The formal atmosphere of the ordinary class room is avoided. The subjects taught are: Arithmetic, elementary drawing, geometrical drawing, mechanical! drawing, geology, construction and use of mine maps, first-aid @ the injured, time-keeping, mine sampling, ng methods, and business correspondence.

The holder is in tended to take a 6-in. length of square Stel lite and support it on the bottom and the back, the cutter being held in place with hol- low set screws which are relied upon to pro- vide the rigidity re- quired for tools of this “Weel Suchaie Gk & Sunliee kind. By moving the Cutter Intended for Use n a holder through an are joring Mill or Vertical Turret of 90 deg. it is possible Lathe to secure either a right or left-hand tool with clearance and side slope either way. ey 980 THE IRON AGE Octo!

The New England Labor Situation rhe public vestigation of the labo: itu Worcester, Mass., last week, by the State Board Conciliation and Arbitration, brought about no chang in the conditior of the str iggle in that ty \ great mass ot evidence lence was submitted by both employ ind employees and is now under consideration by the board The manufacturers refused to enter into anv form of arbitration, although without exception the emplovees expressed a desire for th is form of settlk ment The employers stated their conviction that industria peace was impossible as long as the labor leaders from ou side remained in the city. The Crompton & Knowles Loom Works offic als, at the request « f the board, held another conference with the emplovees Oct 22 but offered no compromise and, at a n e ting later in the day, the latter voted to go out Oct. 28, to enforce thei demands, which are the same as those submitted to the other shops of the city. There is so far but little evidence of weakening by any of the parties t the controversy. A portion of the employees of the 1 oO Cw Drill Company, Athol, Mass., walked ut Oct. 18, whe their demands for an &8-hr day and an increase it wages were refused. It is expected that the State Board of Arbitration will take a hand in the controversy The strike at the plant of the New Britain Machi: e Company, New Britain, Conn., has by vote of the strikers. An effort by the Hartford Chambe: to bring about a settlement of the st peen declared off Commerce ike at the plant of the Pratt & Whitney Mfg. Company, Hartford, Con has not been successful. In refusing to meet a com mittee from the chamber, Vice-President B. M. W Hanson of the Pratt & Whitney Company sent a lette: in which he respectfully declined to discuss the affairs of the company with anybody not in the employ. He stated that a large number of on strike have returned, and they as wel ompany’s workmen as the work men that stood by the company have expressed thei: appreciation of the company’s treatment of its i er ployees in several interviews, and he believes this is the sentiment of the majority of the strikers when left to their own judgment. The machinists employed in the mills of the Ludlow Manufacturing Associates, Ludlow, Mass., on Oct. 19 demanded shorter working hours and a readjustment of wages. Through the efforts of the State Board of Conciliation and Arbitration a compromise was reached on all the demands except an increase of 25 per cent in wages. It was agreed to leave the settlement of this point in the hands of the board. The strike at the Duckworth Chain Company, Springfield, Mass., has been settled by a compromise agreement. In substance, the agreement is for a 48-h1 week with pay as previously paid for 54 hr., time and a half for overtime and double time for Sundays and holidays. All women employees shall receive a mini mum wage of $8 a week after six months’ experience, and the wages of piece workers shall be adjusted so that they will earn this minimum. All matters which cannot be settled by the foremen or the shop commit tee shall be submitted to the State Board of Concilia tion and Arbitration, whose decision shall be final. No provision is made for a closed shop or for open recog nition of the union. The labor agitators are still active in Providence, R. I., but no additional shops have as yet been affected The strike at the Brown & Sharpe Mfg. Company’s plant is practically ended, as most of the men are back at work or have left town.

Safety Convention at Philadelphia How the Movement for Safeguarding Employees Has Grown Illustrated by Size of National Safety A registration of over 1100; an attendance which probably exceeded 1500 in the numerous sessions which it held simultaneously, and an intensity of interest un- usual for the meeting of a more or less technical society tell something of the remarkable growth and widening scope of service which the National Safety Council has reached in its three years of existence. The recognition of the special safety problems attaching to a given industry were shown this year in the arrange- ment for special sessions for these several industries, and so numerous was the representation of these in- dustries and so urgent the demand for the specialization that an iron and steel section, for example, was organ- ized this year. The meeting was the fourth annual of the National Safety Council and was held in the Belle- vue-Stratford Hotel, Philadelphia, Oct. 19, 20 and 21. It is probable that in all 100 papers and reports were read. Such interest was manifested that one of the more general sections devoted to the safeguarding of machinery, of which section Robert J. Young, man- ager of the department of safety and relief of the Illinois Steel Company, Chicago, was chairman, had to be continued from the one day to the other. A refer- ence to the different sections and a list of the papers were given in THE IRON AGE of Sept. 23. On Thursday morning was held the section devoted to foundry safety problems, with Dr. Richard Moldenke, Watchung, N. J., as chairman. This section like others was exceptionally well attended, and an idea of the caliber of the proceedings may be obtained from the subjoined brief account of that particular section. The present convention brought about the consummation of definite organizations for each section, each to have its own officers and committees and thus to pay attention to its own problems. So far as the foundry section is concerned the following were elected to serve the ensu- ing year: Chairman, O. J. Fehling, manager National Malleable Castings Company, Chicago; vice-chairman, F. G. Bennett, safety department, Buckeye Steel Cast- ings Company, Columbus, Ohio, and secretary, Earl B. Morgan, safety engineer, Commonwealth Steel Com- pany, Granite City, Ill. The scheme of sectional organi- zation includes four standing committees, as follows: Membership, standardization, the causes and remedies for hazards, and a program committee. NEW OFFICERS At a banquet which the National Safety Council held on Wednesday evening, at which speeches were made by the Governor of Pennsylvania and the Mayor of Philadelphia among others, the new officers for the ensuing year were announced. R. W. Campbell, chair- man of the Central Safety Committee of the Illinois Steel Company, who has been president since the in- ception of the present movement, could not be induced to retain the office longer and the new president is Arthur T. Morey, assistant to the president of the Commonwealth Steel Company, Granite City, Ill. Lew R. Palmer, chief inspector of the Department of Labor and Industry of Pennsylvania, Harrisburg, Pa., was re- elected first vice-president; C. W. Price, assistant to the Wisconsin Industrial Commission, Madison, Wis., was made the second vice-president, and Edwin R. Wright, president of the Chicago Typographical Union No. 16, was re-elected third vice-president. W. H. Cameron was re-elected secretary, and in making the announcement retiring President Campbell paid special tribute to him for his efforts in behalf of the society. Marcus A. Dow, general safety agent of the New York Central Lines, was elected director of the exhibits and J. J. Lamont was re-elected assistant secretary. As a recognition of the fact that the Na- tional Safety Council grew out of the safety activities Council—Meeting of Foundry Section of the Association of Iron and Steel Elec: neers, that association was elected to ho: bership through admitting to that grade i: officer. The new president in his capacity as attorney fo the Commonwealth Steel Company and in the investi. gations incident to the application of workmen’s com. pensation law to the works of the Commonwealth Steel Company, emphasized the desirability of working ¢. pecially to minimize accidents and in this met the hearty approval of President Howard of that company, As a result, his work as assistant to the president of the Commonwealth Company has resulted in his paying special attention to the elimination of accid
