The production sheet~ illustrated herewith shows the planned production of parts to build the scheduled number of units promised (these may be trucks of from 1 to 5 tons rating, passenger busses, passenger cars or motor street sweepers). ’rinted on this sheet as shown are the part num- ers of trucks scheduled, amount of finished parts in stockroom, number of parts per truck (listed nder class), total number of parts required, on brder and left over, and under the days of the ionth at the top and to the right the number of ssembled units planned for each day. Produc- tion lines are drawn opposite each part number as shown and indicate how many trucks can be built with the parts scheduled and at what date the materials must be finished in the machine shop to keep up the assembly process. Close tab is kept on every job by means of the operation tracer card, illustrated herewith, on which is printed all information pertaining to the job as shown. The card is made in different colors for different departments and classes of work. Blue, for instance, is used for standard pro- duction, red for repair and mail-order work, and yellow for “sent-ahead” jobs. All work is ordered into process by the planning department as “Reg- ular Production,” “Repair” or “Special Work.” No material can be issued from the stockroom without the tracer card, since the card is, in fact, the order to commence work. Two detachable receipts are provided as shown, one being filled out and signed by the stock clerk when the card is sent to the stockroom as a requi- sition for material, and the other by the foreman on receipt of the material, who then sends it on to the planning department. The operation card minus the detachable receipt is next assigned by the foreman to one of the workmen under him who ‘tion Pertaining to a Job Is Printed on This Operation Tracer Card, Which Follows the Job Until Com- pleted, 183 When each operation is finished and approved the card is punched in the O.K. column 4 ‘ 184 ™*" — OPERATION TRACER TBO. porn, Amt en _Dwg.

Shaw, director of safety. To carry on this safety work the department employed four general inspectors, five special inspectors, one stenog- rapher, two educational men, one bacteriologist, and one hygienic man, with seven men to clean drinking fountains twice daily and spray disinfectants through- out the plant. Approximately 2700 orders and commu- nications were issued and completed to prevent acci- dents during the past year. A continual educational campaign has been carried on by two educational men. Bulletin boards, safety slogans on the back of all clock cards, safety moving pictures, talks by foremen, etc., were some of the de- vices utilized to push the safety educational campaign. As the result, for instance, of talks by 107 foremen on the specific hazards encountered in their particular work, 27 per cent reduction in accidents was directly noticed. The idea of lining up men at the street cars devel- oped by the Ford people and known as the Ford idea, it Norton Co. Buys French Plant The Norton Co., Worcester, Mass., has purchased a large controlling interest in the Compagnie des Meules Norton, which operates a large modern plant at La Corneuve, a suburb of Paris, manufacturing grinding wheels of aluminous abrasives. The Norton Co. takes’full charge of the management and operation of the plant and of the distribution of the product. The works will be under the supervision of William La Costa Neilson, vice-president and foreign sales manager of the Norton Co., whose headquarters are in London. Thomas S. Green, recently of the Worcester sales organization, will be resident manager. The business was established two years ago as the Compagnie General des Meules, by French interests, consisting largely of men active in the metal industries of their country. They erected the plant, which has six 15-foot kilns, and an expanding capacity of 12 kilns. It will employ between 100 and 150 men and will manufacture Norton wheels for the French trade. The Norton Co. was approached by the French owners some months ago because of their desire to ally themselves with a company having long experience in the manufacture of high grade wheels and abrasives. The result was the purchase of a majority of stock by the Worcester company, which will have a majority of the board of directors. The name was changed to the Compagnie des Meules Norton. The Norton Co. already has plants in Canada, Japan and Germany. Just before the war the company ac- quired a tract of land in Leicester, England, and was planning to establish works on the premises. The war compelled the abandonment of the project for the time being. There is no intention of going ahead to the ful- filment of that plan in the near future. Fatigue Properties of Aluminum In a paper entitled “Fatigue and Impact Fatigue Tests of Aluminum Alloys,” read before the American Society for Testing Materials at its twenty-third an- nual meeting recently held at Asbury Park, N. J., W. A. Gibson described an investigation to determine the fatigue properties of cast, forged and heat-treated THE IRON AGE July 22, 1920 is pointed out, is growing throughout the country. Agitation for this method of boarding cars has been found advantageous in preventing fights, broken arms etc. A special inspector is employed for watching th punch presses, which every one will admit provide th greatest finger hazards in modern industry; but with the complete guarding and installation of various types of safety devices originating in the press department, such as the two-hand and push-button tripping devices, a great reduction in accidents on punch presses has been noted and it is declared that the machines are now practically as safe as other machines in the plant. A special inspector for use on cranes and elevators, and another special inspector for grinders, suction and exhaust systems, welders, enamel bake ovens and stacks have assisted greatly in reducing accidents among men who work on these equipments and have also helped very much in improving the working co: ditions among these men. Lost time grinder accidents, for example, were practically eliminated and in five particular tases, eyes were known to have been saved by the wearing of goggles. Moreover, in the piston and piston ring departments the suction systems have removed the cause of requests for transfers from 22 per cent to 3 per cent. In the report it is also pointed out that 75 per cent of the accidents were eliminated during the last six months at the Ford ship plant. At the Ford blast furnace plant, elaborate plans are also being developed for safety propaganda work. It is hoped to make these two auxiliary Ford plants as efficient, so far as safety work goes, as the huge automobile plant at Highland Park. aluminum alloys, and to relate these properties to the corresponding properties of steel alloys used in places where it is thought aluminum might advantageously be used. Results of a series of tests were given upon two types of cast alloys in fatigue and in impact fatigue. Results of three series of tests in fatigue were also given upon forged duralumin, with and without heat treatment. One series of tests was given upon a heat- treated carbon steel. In impact fatigue, a series of tests were given upon various duralumins and upon a very mild steel, a heat-treated carbon steel such as is commonly used in forgings, and upon a nickel steel. In comparing the fatigue-resisting properties of forged duralumin with those of the common grades of steel forgings, the conclusion is drawn that for sec- tions of equal size the aluminum alloys are equal tc, if not superior to, forged steel. Larger Supplies of Manganese The scarcity of manganese which seemed to threatening the United States earlier in the year is no probable now. The output of ferromanganese has bee! steadily mounting each month until in June it reached 26,265 tons, according to the blast furnace reports 0!

The average for the second qua! ter is 5300 tons per month larger than that for ‘! first quarter, or 23,318 tons against 18,049 tons pe! month.

But it was from this pioneer New England business that grew our iron and steel try, which to-day leads the world. Many early settlers of Massachusetts crossed the Atlantic for religious freedom, but they, as well . as other's who settled elsewhere in this country, were i npressed with reports of the metals to be found in a the New World. Plymouth, Mass., it will be remem- a bered, was settled in 1620. Lynn, Mass., or Saugus as Cash Is Lacking a then called, was settled in 1629, and very shortly granted the company by the court. The company itself and those who worked for it were released from taxation. Its workmen were not obliged to go to church, which in those orthodox days was a highly j significant concession In addition, the company was given free use of all materials for making or molding pots and all other kinds of cast iron ware. In Septem- ’ ber, 1645, Richard Leader, in behalf of the company, bought of George Ruggles, Braintree, Mass., 25 acres as a forge site, and in the following year this forge was constructed, as nearly as can be figured by records, 1G Not long afterward, Mr. Winthrop, Jr., removed to Connecticut to engage in the iron making business. From that time on the affairs of the Saugus Iron Works appear to have grown more and more complex, due primarily to the lack of cash, the diminishing supply of ore and lawsuits. a a vard iron ore was discovered in the flat meadows ipper parts of the Saugus River.

But payment for products more often was made in grain, wood, and other commodities than which made it necessary to try constantly to raise funds by the sale of shares in the company. And that desire of the American people to sue the corporation have originated with the Saugus Iron in specie, appears to Works. There were frequent lawsuits in and previous to 1651, arising from the overflow of water. Then, too, fear that the works would cause a scarcity of timber also appears to have added to its unpopularity. As one authority stated in 1677, “the company was very much promoted and strenuously carried on for some time, but at length, instead of drawing out bars of iron for the country’s use, there was hammered out nothing but contentions and lawsuits.” Site Well Selected The works, however, was in active operation about 46 years. It was built on 60 the westerly bank of the SAugus River, formerly owned by Thomas Hudson, who is believed to have been a relative of the Hudson for whom Hudson River was named. The site was well situated as it was at the head of navigation, by a ford in the Boston-Salem highway. From various authorities it is certain the iron was near bog ore deposits, yet the exact location of these was revealed in writing or by evidence of development. These bog ore deposits prob ably law a few inches below the surface soil. The top or surface soil may have been loosened by plow and then shovel, the ore, brown in being easily accessible. As the years passed, the top soil which removed from the immediate vicinity of the ore deposits returned to its approximate original acres on selected, works deposits never removed by color, thereby was not location by the action of the river waters, and trace of the ore deposits, therefore, was lost. It certain, however, that the ore deposit was n Adam Hawkes’ meadow. Diligent search in records by the and by other interested persons fails to uncover any detailed description of the works and the exact methods em- ployed therein. Legislation and litigation records fur- nish numerous clues and these, coupled with common foundry practice in England at that time, provide a reasonable basis for deduction. The Saugus Works, it is certain, then comprised a blast furnace, a bloomery or forge, and what in these modern days would be termed a machine shop. Work Charcoal was the common fuel used in those days, coke then being unknown, and by it the bog ore was reduced in the blast furnace. In New England to-day, at least two irons, Salisbury and Richmond, are pro- duced by charcoal fuel. is reasonably ynewhere autnor Water Put to The Saugus Works used oyster shells for fluxing, a practice which has by no means become extinct by use of prepared fluxes.

The fall of water from the sluice gate to the was slight, but the total fall from the basin to river below was in the neighborhood of 50 ft. 1 basement of the iron works was about 30 ft. the basin, so that by this arrangement the upper was on, or practically on, a level with the pa around the basin, which permitted charcoal and ore to be fed easily into the upper part of the furnace. “ Slag from the furnace and cinders from the bloo or forge were taken from the basement and du at the ssuth end or side of the works, and recent years remained a conspicuous reminder of industry that once flourished there.

Provision is also made for the construction of a house buildng program for the employees. Fifty homes will be constructed immediately on a plot lo cated in the middle of the grounds. In close proximity to the new homes will be built a company hotel, which will also form a civic center. For the present the hotel will accommodate 50 people, but will be provided with an auditorium 30x100 ft., with baths, gymnasium, billiard and pool tables, and bowling alleys. Lackawanna Company Earnings Improved An inerease in both profits and unfilled orders is indicated in the report of the Lackawanna Steel Co. for second quarter of 1920 over the second quarter of 1919. Profits this quarter were $1,881,946, contrasted with a deficit of $233,086 the second quarter of 1919; unfilled orders amounted to 484,267 tons the 1920 quar- ter, against 122,399 tons a year before. Total net earn ings after taxes and ordinary repairs were $2,786,107, compared with $446,757 the year before. At the end of the first quarter of this year there was a deficit of $449,720, though the unfilled orders were slightly greater than at the end of the second quarter, being 492,519 tons. The company also contrasts earnings the first half of this year with those of the first half of 1919. They were $1,432,225 this year and $974,022 last year. New Company to Make Non-Ferrous Alloys A new maker of white metals is the Pan American Smelting Works, Brooklyn, N. Y.- A building of brick, ‘onerete and glass, 75 x 150 ft., has recently been com- pleted on the corner of Calyer and Moultrie streets To facilitate the handling of incoming and outgoing shipments, the loading floor was built truck-floor high. Babbitt metals, phosphor alloys, type metals, solders and white metal alloys are the main products. They are marketed under the following trade marks: Cast vell, Aero Marine, Standard U. S. Genuine, Durabel, lowell and Rapid Transit. The president of the com pany is George Stoll who, previous to the organization of the Pan American Smelting Works, was connected with the United Metals Corporation (Syracuse Smelt- ing Works’ Subsidiary) as assistant to the president. Mr. Stoll recently returned from a two years’ trip to the Orient and the Far East in the interests of firm. Abraham Saffer is the treasurer.

The machine is adapted for measuring lengths, angles and pitches. It does not depend on screws for its accuracy, but upon end measuring rods and large-dial micrometers graduated to 0.0001-in. It s explained that the measuring rods which are used in making all length measurements maintain their ac curacy indefinitely and can be readily checked by well- known means. A box bed carries 12-in. move- ment by accurate amounts through the insertion and removal of standard hardened of known length between flat hardened; these pleces are mounted one on the end of the bed and one on the end of the table The le is fitted with a pair of centers, yages, troduced into this a table capable of steel measuring rods contact pieces, also contact tad Screw-Thread eurate Measurement of Articles It depends for it accuracy upon one of which is adjustable in a crosswise direction to enable work to be lined up accurately. A microscope with vertical movement by rack and pinion for focussing is mounted on a compound slide rest, with screw movement parallel] with the slides and at right angles to the table slide. The microscope is fitted with two hair lines across its diameter, one ro- tating with the outside tube and the other rotating with the eyepiece. The outer tube carries a graduated in half degrees. The eyepiece carries a vernier, which enables readings accurate to one minute to be made. Thus the angle between the two hair lines is indi- cated with fine commercial accuracy. A light projector is fixed to the machine to project parallel rays of light through a lens upon a mirror placed at an angle and so past the work. When meas- uring threads this attachment eliminates shadows and light projected from the flanks of the thread which tend to make the object indistinct. The mirror is ad- justable to suit the lead of the thread, and enables the object to be clearly defined through the microscope. Eight-volt accumulators are required for this attach- ment, but are not included in the standard equipment. The table is 22 in. by 3% in.; greatest length meas- ured, 12 in.; maximum diameter of work, 3 in.; mag- nification of microscope, 25 diameters; overall length of machine, 36 in.; overall width, 10 in.; overall height, 18 in.; approximate net weight, 214 lb. large dial The Stanley Belting Corporation, 32 South Clinton Street, Chicago, has been appointed special distributor for the Bull Dog shaft couplinys and collars, made by the Safety First Mfg. Co., Alexandria, Va. AGE July 22, 1920 Cylinder Reaming Sets A new cylinder reaming set has been added to its line of reamers by the Wetmore Reamer Co., Milwau kee. The set consists of a roughing reamer, semi finishing reamer and a floating finishing reamer. The roughing reamer has adjustable and replac able blades set at a right hand angle. The semi-finishing tool has left hand angle blade: like the standard Wetmore floating reamer to eliminate “digging in” and “chattering,” thus to produce a round hole that is not scored when backing out, leaving a: ideal condition for finishing. A modification of this reamer is designed for line and pilot reaming. The floating finishing reamer has a feature in tha the float is in the head of the too] directly under th strain, thus to eliminate tendency to get out of parall: or cramp. The float is an improved Oldham type, having rollers instead of sliding contacts reduce friction. The float mechanism is pro tected from dust and grit by a cap covering the front and a washer protecting the back. The blades are set at a left-hand angle and Tools, Form Tools, Gages, Threaded Work and Similar end measuring rods and irge dial micrometers staggered. Expansion and adjusting to thousandths ot! an inch are made by a graduated micrometer lock nut located at the rear of the blades. Present standard sizes are 2 7/16 in. to 5 9/16 in.

RICHARD NY discussion on the production of good castings will always bring out at least two strong view- points. There is that of the purchaser of these astings who invariably wants them to be perfect and heap. Only in times like these must he take practi- ally what is given him and at figures set by the indryman. These times, however, will not remain very ng, and the foundryman will shortly be confronted vain with strict demands for smooth surfaced, sound, ng and machinable work at low, competitive figures. Hence the importance of keeping up quality production spite of the temptation to let everything pass out of shop. From the standpoint of the foundryman it is equally ential that the work produced should be of high iality, for every rejected casting costs as much as the responding good one, and yet, on remelting, has only rap value, for it can be replaced thus in the open <et. Few foundrymen realize that molten metal ted in unnecessarily large risers and pouring basins, led and “over-iron” comes under this category and ild therefore be reduced to a safe minimum. For s reason also should the breaking in of new men be owed up carefully to judge whether within a reason- each man has made sufficient istify the further losses still ahead before adjudging m a skilled operative. Molding is an art, even if a hine performs a part of the work, and not every is gifted with the necessary qualifications. rom the view-point of the nation as a whole, it is tial for the economic advance of our industrial life the pound of iron be made to go further than and hence the indiscriminate masses of metal must give way to material of er grade in construction work of modern tent with the requirements of service and incumbent, therefore, upon the foundryman to every phase of the numerous processes involved work so that he may know himself to be indus successful, as well as commercially so.

First: It is nec- work with good materials in foundry pro- All melting processes are necessarily oxidizing icter to a greater or less extent, and hence an iron or “burnt” scrap is not subject to im- nent by remelting. Again, a molding sand full of may mean disaster to the surface of a heavy while high sulphur coke will surely increase rap pile. Second: Even with the best of mate- rood results will not be achieved unless these s are put through the necessary processes with red degree of skill and attention. Hence good must be made from the right kind of sands, and | surfaces must be properly finished and black- Good pig irons and carefully selected scrap must rged judiciously and melted under practically per- ‘urnace conditions, so that when the molten metal d out, the foundryman may be certain that it iave been no better for the class of work in hand. ? ess de livered Southern -21. convention of the Atlanta, Ga., Juge 20 at the Association at 191 Iron and Serap MOLDEN KE Finally, the gating of the molds and riser arrange- ment should be planned and carried through with sci- entific accuracy, if such a term may be used in a foundry. Then the carefully selected materials which have been melted under exact charging and blast condi- tions and have yielded a molten metal full of life will be given a fair chance to be converted into castings free from undue internal shrinkage, casting strains and other trouble. The above three points are the fundamental ones the foundryman must constantly bear in mind, and if followed out carefully by properly trained men, should lead to good castings produced economically. Of what avail is it to fill up a floor with molds only to lose a large percentage through sand troubles; or to make fewer but perfect molds and lose a lot of castings by oxiding metal through poor melting; or with perfect molds and excellent molten metal to get castings full of internal shrinkage through improper feeding oppor tunity as the result of poor gating. Unfortunately, in the last mentioned instance, the defects are usually not discovered until the castings have failed in service. The foundrymen cannot be too watchful in all these opera- tions and must insist on every care on the part of the operatives, for his and that of the buying public. A more detailed discussion of these three fun damental points will, therefore, seem not amiss at this juncture. own rood The Sulphur Problem tragic industrial condition of the world during the perhaps best illustrated in the With pig iron and coke almost beyond reach and necessarily poorly made; with labor below all com- parison with anything the foundry has had to suffer in its history, no wonder there is a surfeit of abominably high sulphur, low grade work in existence which is accumulating trouble in the industry for this and the generations to come. It will require a high order of industrial education to cope with the situation when the castings made since the war began appear in the scrap pile. As the strain in our industries tapers off, the furnaceman will again obtain better fuels and ore and can, if he will, furnish bétter-made pig metal. Competition will eventually bring the foundryman bet- ter fuel, and it is only the scrap which he has to buy that will give him concern as regards his raw materials. While a high pig percentage in the mixture helps overcome the sulphur difficulty to some extent, this is not always practicable in times of sharp competition, and hence only a thorough knowledge of cupola charg- ing and melting will give fairly satisfactory results in spite of the scrap handicap. Since it is possible to make servicable and machinable castings with sulphur as high as 0.30 per cent, provided everything else is cor- rect, there is no reason why the foundryman should not be able to hold his own. There are, however, few foundrymen who are posted so thoroughly and can work in the exact routine the necessity of the case demands. Hence there is bound to be much disappointment ahead. The question of molding sand is becoming more serious in some sections of the country. The best deposits are verging upon exhaustion, and there is need of more careful sand preparation in the shop, to correct the difficulties with the natural product. Eu- rope is ahead of us in this particular, in many in- stances all of the sand used daily going through ma- chines for regrinding and mixing. Thus, after remov- ing the burnt sand adhering to the casting as shaken out, and with the me t economical use of sea-coal, The and since foundry. war 18 ever serious 192 THE IRON enough new sand is ground in to keep up the quantity and bond of the heaps to standard. While the eventual solution of the sand problem lies in preparing it arti- ficially, from even-sized rounded grains of clean silica coated with high refractory and fat clays, much can be done by grinding the natural sands to promote their uniformity in texture and bond. As time goes on, foundrymen will demand better sands, and the sand merchant will have to add equipment to his plant to produce the goods. In the meantime, however, foundry- men will do well to test their sand-heaps regularly for fineness, strength and the bonding value of the clay content. Further, they should classify their work into light, medium and the heavy grades and arrange the sand heaps accordingly, and see that these heaps are not mixed. A fine sand mixed with a coarse one sim- ply reduces the venting power of the latter without giving very much smoother work. As regards the finishing of the mold surfaces, there is this much to be said. Molding sand
