An entirely new line of vertical boring and turning mills is being built by the Colburn Machine Tool Com- pany, Franklin, Pa., to which the name “ New Model” has been applied. With the exception of the method of driving the table the same features are incorporated in all the five sizes built (42, 48, 54, 60 and 72-in. swing), and a description of the 60-in. mill (Fig. 1) given in the following practically describes all the bearing in the following manner: The lower part of the cone is immersed in a reservoir of oil and immedi- ately when the spindle starts to revolve the oil is car- ried upward to the outer edge of the bearing and into an annular channel, from which it is returned through grooves to the main reservoir again. The conical bearing is thus automatically flushed with oil con- stantly, and the oil flows over into the upright bear- Fig. 1—A 60-In. New Model Vertical Boring and Turning Mill with Two Swivel Heads and Plain Table, Built by ithe Colburn Machine Tool Company, Franklin, Pa. others. All sizes are built with two swivel heads, and the three smallest sizes with turret heads if desired. Fig. 2 shows a 42-in. mill with one swivel head and one turret head. The Main Spindle and Table Gear, Referring to Fig. 3, and the line drawing Fig. 4, it will be seen that the table spindle has a massive angular thrust bearing which makes it self centering and, together with the large straight upright bearings, effectually resists vertical, angular and _ horizontal strains. All bearing surfaces of the spindle are lubri- cated from one sight feed oil cup. The proper hight of the oil is always shown by a mark on the glass. A constant flow of oil is maintained on the large conical ings; a circular safety band of felt set into the bear- ing at the top retains enough oil to keep the bearing from becoming dry, even if no oil is put into the cup for a long time. : The table is driven by a spur gear of large diame- ter attached directly to the table itself. No lifting tendency is possible with this style of drive. An ex- ternal spur gear drive is used on the 42, 48 and 54-in. mills, and an internal gear, as shown in Fig. 3, on the 60 and 72-in. mills. The Driving Mechanism, The drive is from five-step cone pulleys of large dimensions, thence through the speed box, containing the back gears and positive clutches, which are con- CO REO ENO He EIR Ge leer 298 wk ewe a eae tae Fig. 2.—A 42-In. New Model Vertical Boring and Turning Mil! with One Swivel Head and One Turret Head and Plain Table. stantly immersed in a bath of oil. The back gears are engaged and disengaged by positive clutches inside of speed box and operated by the lever A, conveniently located at the side of the machine (as shown in Fig. 5). Five speeds are obtained with the back gears out, and five more with the back gears in, making Io speeds in all in geometrical progression. The speed box when assembled is perfectly oil tight, and the proper hight of oil is shown at all times by the sight feed oil cup on the outside. All the bearings have phosphor bronze bushings, and ring oilers for additional protection against heating. The oil runs directly into the ring oiling pockets from the main reservoir (as shown in Fig. 6). By removing a plug under the sight feed oil cup the entire box can be drained dry. Should it be necessary at any time to make repairs the speed box can be quickly removed from the machine in its en- tirety, and every part is then easily accessible. §The Cone Pulley Mechanical Belt Shifter, A belt shifter (B, Fig. 5) is furnished on these mills, which is so simple, effective and easily operated that it appears to offset the advantage of a single- pulley drive, particularly when the more or less com- plicated mechanism and multiplicity of parts of the Fig. 3.—Detail of the Table Spindle Bearing and Internal Gear Drive as Used on 60-In. and 72-In. New Model Mills. THE IRON AGE latter is considered. By means of this shifter, operated entirely with one hand, the belt can be changed from one step of the cone pulley to another very rapidly and without injuring the belt. In actual operation the entire range of speeds obtained with the cone pulleys, from the slowest to the fastest and back again, stop- ping momentarily on each step, has been made in eight seconds. By changing the back gear lever, A, which is in close proximity to the handle which operates the belt shifter, another run of five additional speeds is obtained. A speed index plate located on the housing directly above the back gear lever A indicates the step on the cone pulley for the belt, and the position of the clutches inside of the speed box corresponding to each speed of the table in revolutions per minute. The Countershaft, The countershaft is attached directly to the upper part of the housings by brackets having ring oiling bearings and thus becomes a part of the machine it- self. It carries the upper cone pulley and tight and loose pulleys. The loose pulley is self-oiling, with bronze bushings, and is made smaller than the tight pulley, so that the strain of the belt is removed when the machine is not running. The belt from the line shaft can be shifted, thus starting or stopping the machine from either side of the mill, by a horizontal rod having a spade handle at each end. This rod con- nects with a mechanism for shifting the main belt running to the line shaft. The Foot Brake, To enable the operator to stop the machine with the table in any desired position, a friction brake is TABLE-OR/CHUCK om >. SPINDLE j 5 cl te : Pea SS rt sa f “ y | Up ys G 1 | TABLE PINION Fig. 4.—Vertical Section Through the Table Drive. furnished, which is operated by a foot treadle placed within easy reach at the operating side of the machine. The brake is applied to the inside of the lower driving cone pulley by a taper friction with three hard maple shoes or wedges, B, Fig. 7. These wedges are specially treated by being boiled in parafine. The conical type of friction prevents distorting the bearings and, operat- ing directly upon the prime mover, all shock and jar is eliminated, and the braking effect is instantaneous. In actual operation the mill can be stopped and started, all the table speeds changed, back gears thrown in and out and the foot brake applied without the operator leaving his position at the side of the machine. In operating the mill it is not necessary to go around back of the machine. The Cross Rail, Saddles, Swivels, and Rams, The cross rail is of box type, with deep arched back, and is of extra massive proportions. It is raised and lowered by power. The saddles, as shown in Fig. 8, are mounted on the cross rail and have unusually long and liberal bearing surfaces. Adjustable taper gibs compensate for wear. The swivels are of large diameter, with broad bearing surfaces, and the metal over the T-slots is extra heavy, to withstand the strain of five. large clamping bolts. Angular adjustments are December 30, 1909 Si ti a th a ha x. Cerise i 3 ¥ December 30, 1909 made by a worm and gear, which also acts as a posi- tive locking device, making it impossible for the heads to accidentally fall over sideways when the clamping bolts are released. The rams, A, Fig. 7, are very massive and have steel racks set into their sides. Cored openings extend clear to the top, so that extra long boring bars can be used. The rams rise within the guides, so that the bottom of the tool holders will be above the lower edge of the cross rail. Feeds, The feeding mechanism for each head is contained in a separate case, one on each side of the mill. By turning the hand wheel one revolution five changes of feed are obtained. A movement of the multiplying lever changes the combination of gears and another revolution of the hand wheel gives five more changes, THE IRON AGE 1921 tion, and the tool will feed in the direction determined by the position of the feed reverse lever at the end of the cross rail. The rapid traverse is always engaged when the lever is in the forward position, and the tool will travel rapidly in the opposite direction from the gear feed. It is impossible for the operator to throw the rapid traverse in the wrong way, and there is no chance for an accident to occur. To illustrate: Sup- pose the tool was feeding horizontally along the rail taking a cut on a piece of work. Having reached the end of the cut, say, with the tool up against a shoulder, the operator now desires to disengage the feed and return the tool to the starting point again for a finish- ing cut. He simply pulls the rapid traverse lever for- ward, and does not have to stop and think which way Fig. 5.—Rear View of a New Model Boring Mill, Showing the Main Drive, Mechanical Belt Shifter for the Cone Pulleys, Safety Shear Pin Device, &c. making 10 in all. The vertical feed shaft extending upward from each feed case engages with mechanism on each end of rail, which conveys motion to the hori- zontal rods and screws in the cross rail, which operate the heads vertically and horizontally. The usual slip gears on the ends of the rods and screws are eliminated and quick adjusting positive clutches are substituted, shown at D in Fig. 7, which enable the operator to in- stantly change the feed from vertical to horizontal and vice versa. Either feed can be reversed instantly by the feed reverse lever shown at each end of the rail. The Power Rapid Traverse, Rapid traverse of the tools, horizontally, vertically and in angular directions is obtained from the same vertical shafts as the feed; the manipulation is by a vertical lever attached to the front of the feed case, which may be seen in Fig. 5. This lever has two op- erating positions, forward and back. The gear feed is always engaged when the lever is in the back posi- to pull it, as there is only one direction in which it can be moved. It makes no difference whether the tool is feeding to the right or left, horizontally, or up or down vertically, the same lever controls the feed and the rapid traverse in every case and pulling the lever always throws the gear feed out and the rapid traverse in, thus reversing the direction of the travel of the tool. This arrangement of gear feed and rapid traverse simplifies the whole process of rapid manipu- lation of the tools, and makes a safety device which is not only theoreticlly but practically fool proof. The motion for the rapid traverse is obtained from the horizontal shaft at the top through friction cones having cork inserts, shown at C in Fig. 7 on the upper ends of the vertical feed shafts. The rapid traverse in connection with the final adjusting collars does away with the necessity of hand cranking, although the ends of the rods and screws in cross rail are squared so that a crank can be used in an emergency or when pre- ferred. sar | enews —— ee iy ees j 1 A 4 q é ite Kane ri Final Adjusting Collars. Although the rapid traverse is an indispensable fea- - ture, enabling the operator to quickly move the tools in any direction, it does not allow a fine adjustment to be made. To accomplish this it has usually been neces- sary to go to the end of the cross rail and make the final adjustment by a crank handle. This is unneces- sary on the Colburn New Model mills. Both feed screws and rods in the cross rail are splined and each has a capstan collar slidably fitted thereto with keys Fig. 6.—Speed Box of the New Model Boring Mill, Showing In- ternal Mechanism and Ring-Oiling Bearings. which fit the spline, so that by turning the capstan collars with a small lever furnished for this purpose the rods and screws are turned also. With this device the operator can stand close to his work, as shown in Fig. 9, and by placing the capstan collars in the most convenient place, make the finest adjustments of the tools in any direction without leaving his position. When the heads are moved out on the end of the cross rail these collars slide back behind the heads, as shown Fig. 7.—Details of Parts of a New Model Boring Mill.

The Safety Shear Pin Device, A safety shear pin device placed on the rear of each end of the cross rail prevents injury to the feed mechanism in case the heads are accidentally run to- gether or from other causes. This device is shown in Fig. 10 in position and also taken apart. The horizontal Fig. 9.—Operation of the Final Adjusting Collars in Making Ver- tical and Horizontal Adjustments of the Cutting Tools. shaft in the foreground transmits the motion of the vertical feed shaft through bevel gears to the train of spur gears at the end of the rail and thence to the heads. This shaft is made in two sections with a lit- tle flange coupling on the ends adjoining each other. Motion is transmitted from the driving end of the shaft to the driven end by a small pin, which passes through each flange of the coupling. Any abnormal strain on the feeding mechanism in excess of that necessary to take the heaviest cuts will shear this pin off and thus protect the gears and mechanism from breakage. When the pin shears one section of the coupling is turned half around until the slots are op- posite the broken pins, which are then readily removed, as shown in Fig. 10. The couplings are then turned until the holes are in line again, and a new pin is in- C Eh , December 30, 1909 Fig. 10.—Two Views of the Safety Shear Pin Device Which Pro tects the Feed Mechanism. At the Left the Couplings Are Turned Half Way Around with the Slot Opposite the Pin to Facilitate its Removal; at the Right the Couplings Are Re moved from the Shafts and the Shear Pin Withdrawn serted and the mill is ready to run. The whole opera- tion of taking out the old pin and putting in a new one only takes a few seconds. There is nothing about this device to adjust or to get out of order. A supply of pins is furnished with each machine and when used up new ones can readily be made from ordinary wire nails. The Thread Cutting Attachment, When cutting threads the feed change hand wheel is set so that the vertical feed shaft and table revolve in unison. A single tooth clutch on the lower end of this shaft insures the threading tool always catching the thread in taking successive cuts, and the rapid tra- verse device is used to return the tool quickly to its starting point. The thread cutting attachment is not furnished regularly, but can be put on at any time. It is attached to the bracket on the end of the cross rail, and is al- ways used for the right hand head. Change gears reg- ularly allow any lead to be cut from 2 to 14 per inch. For drum scoring special arrangements are made which allow leads as coarse as one turn in 2 in. to be cut as readily as the finer pitches. A constant speed motor is recommended for these mills, since the mechanical belt shifter and clutches in Fig. 11.—Constant Speed Motor Drive as Applied to 54, 60 and 72-In. New Model Boring and Turning Mills. THE IRON AGE 1923 the speed box give all the changes of speeds desired. The motor is mounted on a bracket at the rear, and is belted to the pulley on the countershaft; the slack of the belt is taken up by an idler. To enable the operator to stop and start the mill without stopping the motor, a clutch pulley replaces the regular tight and loose pul- leys, and is operated by the same levers with handles on both sides of mill. The arrangement of motor drive is clearly shown in Fig. II. -—_—o+#—___ The Colorado Fuel & Iron ,Company.

President J. F. Welborn presents a cheerful fore- cast for the fiscal year 1910, so that the surplus for the current year should be very much better. The ex- ecutive officers decided early in the present year to have an appraisement made of all the mines, lands and property of the company and its subsidiaries, regard- less of the original cost or book values. As late as 1900 the iron ore properties developed showed but about 6,000,000 tons, while in 1909 there -is de veloped more than 35,000,000 tons. Estimates made by competent experts of the company’s undeveloped iron properties give a tonnage which, with that already de- veloped, is sufficient to supply the steel plant, running at its present capacity, for 50 or 60 years at least. The development of the coal and coke properties during the same period of years shows a large increase in tonnage over former estimates. The estimated value of these properties by experts is more than that now placed upon them and shown in the foregoing balance sheet. re emaaesyn sero, mt f | | | A ope ete Ee Re 1924 THE IRON AGE The Bay State’s Low Cost Life In- surance. A Statement of What Savings Bank Life In- surance Has Accomplished in Massachusetts. It is now some months since The Jron Age pub- lished an authoritative statement* of the details of the Massachusetts movement for wage earners’ insurance to be offered at actual cost to the insured, a scheme which the American Federation of Labor approved at the Denver meeting a year ago and which has attracted a great deal of attention and interest in other quarters. The value of the plan as a theoretical proposition then looked to be undeniable to leaders of organized labor, just as it had seemed incontestable to the legislators of the Bay State who were called upon to consider it in the spring of 1907. A statement can now be made of the first year’s accomplishment of the savings bank insurance system in practical operation in Massachusetts. Two Savings Banks Try the Plan, 1. The movement began with the publication in September, 1906, in Collier's, of an article by Louis D. Brandeis of Boston, entitled “ Wage Earners’ Life Insurance,” which set forth the abuses of the industrial insurance system and proposed as a remedy the estab- lishment of an insurance department in connection with the savings banks. A plan for legislation of this ‘character was submitted to the Recess Insurance Com- mittee appointed by the Massachusetts Legislature of 1906. This plan was unanimously recommended by that committee to the Legislature of 1907. The savings bank insurance and annuity bill was passed June 26, 1907. The trustees of the General In- surance Guaranty Fund, who exercise general super- vision over the system, were appointed in July, 1907. The State actuary was selected by the trustees in Oc- tober, 1907. The large amount of work required of the State actuary and State medical director before the system could be put into operation delayed the opening of the insurance department of any bank until the end of June, 1908, when the Whitman Savings Bank established its insurance department. Even then the preliminary actuarial work had only been in part performed, and it was not until some months later that the system was in what may be called working order. The People’s Savings Bank of Brockton opened its insurance department November 2, 1908. Figancial Showing of the First Year. 2. The financial year of the savings banks begins November 1. The first year, therefore, of the sav- ings bank insurance system in operation closed Oc- tober 31, 1909. The report showing the operation of both the Whitman Savings Bank and the People’s Savings Bank of Brockton has just been made, with the following result: a. The aggregate insurance of the two banks out- standing at the end of the year (not including annuity or pension policies) was about $1,000,000, the policies being 2521 and averaging $393.79. b. The insurance departments earned, after setting apart the full legal reserve, calculated on the most conservative basis, and in addition an amount equal to 4 per cent. of the premiums to the trustees of the General Insurance Guaranty Fund, and paying interest at the rate of 4 per cent. on the special guaranty fund of $25,000 for each bank, a surplus from which they have declared payable to the holders of all of the monthly premium policies a dividend of 8 1-3 per cent. . For the payment of this dividend only 25 per cent. of the surplus profit earned is required. The remaining 75 per cent. of the profits is set apart as a surplus guaranty fund, in addition to the legal reserve and the * See The Iron Age of August 27, 1908, page 575. December 30, 1909 contribution to the General Guaranty Fund referred to above. Of the expenses of the insurance depart- ment during the past year, over two-thirds has consisted of medical fees. The percentage of these to premiums is, of course, unusually heavy in the first year. The State actuary believes that when the system is in full opera- tion the dividend on the monthly premium policies will be much larger than 8 1-3 per cent., and that a dividend of 20 per cent. may reasonably be expected. A leaflet relating to this dividend has been issued from the State actuary’s office, 161 Devonshire street, Boston. Reduced Monthly Premium Rates, 3. The present monthly premium rates are 15 per cent. less than the present industrial rates. Savings bank policies, however, being participating policies, the policyholders, even with the present dividend of 8 1-3 per cent., get a rate which is 23 1-3 per cent. less than that of the industrial companies. Putting it in the other way: The present industrial companies’ rate is about 30 per cent. higher than the net savings bank rate based on this year’s dividend. The rates on the quarterly premium policies of the savings banks, of course, do not show so great an advantage over that of the other companies, but the net rates are believed to be the lowest rates for policies of similar amount attainable in any legal reserve company. 4. The reduction of rates which the savings insur- ance banks offer has been made possible by marked changes in the system of doing business. The indus- trial companies through their solicitors have a house to house solicitation for business and a weekly house to house collection of premiums, the compensation of the solicitors and collectors being directly dependent upon the amount of the business written and, the premiums collected. The savings bank insurance law prohibited the banks from employing paid solicitors and collectors. It undertook to substitute unpaid agen- cies for these, and the business actually written by the banks has come mainly through such agencies. Industrial Insurance Companies Make Reforms, 5. The amount of business done by the savings in- surance banks, and the advantage in rates now offered, will be but a very small part of the achievement of the savings bank insurance movement. Its greatest suc- cess by far has been in its effect upon the industrial insurance companies. When the abuses of industrial insurance—the terribly high cost to the policyholder, the huge expense rate and the forfeiture of policies— were called to the attention of the public, it was as- serted by the industrial companies that their business was admirably managed, and that the high cost to the policyholder and the apparently onerous provisions of the policies were necessary incidents to the business. The lessening of these abuses since the savings bank system was inaugurated has been marked: a. For a period of at least 20 years prior to the in- auguration of the savings bank insurance movement there had been no reduction in the premiums of indus- trial policies. In the three years since the movement was started, industrial insurance companies’ premiums have been reduced on an average of about 20 per cent., the first large reduction having been made as of Janu- ary I, 1907, after the plan was submitted to the Legis- lative Recess Insurance Committee of Massachusetts ; the second, as of July 1, 1909, after the system had been put into successful operation. This reduction will soon result in an annual saving to the working people of Massachusetts alone of $1,- 000,000 to $1,500,000; for the amount of industrial premiums collected by the companies in Massachusetts was, in 1908, $8,062,389. A relatively small part of the premiums of that year had the benefit of the reduced rate, but, as the average life of an industrial policy is less than four years, it will be seen that the saving to the working people resulting from this reduction in nit eae: Tae a re ~ naire at Ee ea December 30, 1909 rates in Massachusetts will, in a few years, rise above $1,000,000 annually. The saving in Massachusetts represents, however, only a small part of the saving to the working people of America from the reduction now made. The total industrial premiums collected in the United States in 1908 was about $90,000,000. It will be but a few years when the saving effected on the volume of insurance represented by such premiums will be between $10,000,- 000 and $15,000,000 a year. b. Another great change to the advantage of policyholders resulting from the inauguration of the savings bauk insurance movement is the in- crease of the amount payable in case of the death of the insured within the first year after the policy is written. For probably 20 years prior to the inauguration of the savings bank insurance movement the policies of the leading industrial companies pro- vided that in case of death within the first six months only one-fourth of the face of the policy would be paid, and in case of death within the second six months only one-half of the face of the policy would be paid. The savings insurance advocates insisted that such provisions were in effect de- lusive, and in view of the fact that more than one-half of all industrial policies lapse within a year, the effect was to make the industrial insur ance for an appreciable por- tion of the average time cov- ered by the policy not only twice as expensive as ordi- nary insurance, but, indeed, four or eight times as expen- sive. The savings bank insur- ance policies provide that the full amount written in the policy shall be payable even in case of death immediately after the policy is written. Since the inauguration of the savings bank insurance movement, the _ industrial companies have made the full benefit of the policy pay- able in case of death six months after the policy is written and one-half payable in case of death within the first six months. c. For the last 10 years prior to the inauguration of the savings bank insurance movement, the two leading industrial companies gave no cash surrender value until the end of 20 years after the date of the policy, and in case of lapse of policy gave a small paid up value after three years, but denied to the insured the right to extended insurance. The Massachusetts savings bank insurance act provided that no policy should be forfeited after premiums covering six months had been paid, and that, in the event that premium payments then ceased, the insured should have either a cash surrender value, paid-up insurance or extended insurance. Since the inauguration of the savings bank insurance movement the two leading in- dustrial companies have changed their policies so as to give extended insurance after three years and a cash surrender value after Io years. Original Advantages of Savings Bank Insurance Have Been Lessened, 6. It is, of course, apparent that the great success of this movement in effecting such important reforms in the abuses of the industrial companies has made competition with them more difficult to establish. The advantages over them in rates and terms which the Bay State savings banks had to offer when the move- THE IRON AGE 1925; ment started have, so far as the policyholders are con cerned, been lessened by half through the reforms which the companies have been induced to adopt. They claim now to have accepted the principle on which savings bank insurance rests—namely, that the working people should be served in respect to life in- surance by a social institution rather than by an ex ploiting business—and have given some evidence of an intention to act upon it. Far more has been ac- complished by the savings bank insurance movement within the three years than even its most ardent sup porters had dared hope for. ————__3--@______- The Perkins Tack Plate Straightener. lor straightening all sizes and thickness of tack plate, the Henry Perkins Company, Bridgewater, Mass., has brought out the machine shown in the ac- companying illustration.

The Journal says that the references made were based upon statements in daily newspapers which purported to give the conditions at the company’s plant at that time, and that after inves- tigation it is satisfied that it was in error and that the article was unjust to Mr. Hoeffstot and his company.

The Pratt & Whitney Company, Hartford, Conn., has recently brought out an entirely new design of surface grinder which, it is stated, will grind from 12 to 20 times faster than any machine now on the mar- ket. One reason for this extremely rapid rate of pro- duction is the cup shape of the grinding wheel, which covers the entire width of the work and insures flat- ness, together with rapid reduction. The table is 15 x 40 in. and the working surface is 1034 x 36 in. Straps or magnetic chucks are employed to hold the work in place on the table, which can be given any length of stroke desired up to a maximum of 36 in. Variation in the length of stroke is accomplished by adjustable dogs, which govern the travel of the table. For grinding disks, rings and collars not exceeding 16 in. in diameter a revolving table 16 in. across is IRON AGE December 30, 1909 blades, file blanks, planer knives, carpenters’ planes, cam shafts and a large number of automobile parts. The grinder is furnished for either belt drive or direct connection to an electric motor. The driving pulley is 14 in. in diameter, with a 6-in. face, and makes 25 rev. per min. If electric drive is used a 7%4-hp. constant speed motor is recommended. ————@—-e—__- Large Toledo Presses. The rapid development of a type of all steel con- struction which is being substituted for the former wooden construction of automobiles and motor vehicles in general renders the two powerful presses designed and built by the Toledo Machine & Tool Company, Toledo, Ohio, of particular interest. These machines which are shown in the accompanying illustrations Fig. 1.—The No. 97 H Press for Automobile Frames Built used. The drive for this table can be engaged or dis- engaged at will without stopping the emery wheel. A bushed hole in the center of the table is provided for inserting plugs to hold the work on the table. This is the only means required for holding the work, but a special type of circular magnetic chuck is furnished for special work. Ten automatic vertical feeds of the slide are ob- tained through a ratchet wheel, each tooth of which represents a feeding movement of 0.0002 in., so that rates of feed varying from 0.002 to 0.02 in. are ob- tainable. The vertical spindle is hollow, thus allowing a lib- eral supply of water to pass through, while the centrif- ugal force of the wheel, due to its high speed (1100 rev. per min.), drives the water between it and the work and thus keeps them both cool and free from dust. In- dependent bearings are provided for the spindle, so that it is not affected by strains from the driving belt. Among the different kinds of work turned out by this machine are flatiron bases, circular saws, gun hammer blanks, gun ejector levers, pistol frames, knife by the Toledo Machine & Tool Company, Toledo, Ohio. are intended for cutting and forming the steel bodies and frames for automobiles. The press designed for pressing up or forming the side and cross channels for the underframe of automo- biles is shown in Fig. 1. As all this work has been done heretofore by hydraulic presses, it is interesting to note how the press which makes eight strokes per minute does its work. In the illustration the dies are in position to perform the operation of making an underframe. To prevent distortion of the steel strips under the pressure applied, which is nearly goo tons, the lower die is fitted with a pressure attachment. A novel feature of this press is a motor driven elevating attachment for adjusting the slide, which is both large and heavy. This attachment is operated by a 4-hp. motor mounted on top of the frame arch. The power is transmitted to the rear shaft by sprockets and chains and then continues over to the worm shaft engaging with worm gears on each of the right and left pitman screws. A reversible friction clutch is provided for this attachment just below the motor, and is fastened to the arch in the rear, and is therefore not visible. Pa. ~aalie ieia 7s nag seat Bo aL BE Sas i ee ee ae oa py fee December 30 This clutch is controlled by the lever and segment upon which the man’s hand is resting. The press itself is fitted with twin gears on the crank shaft, which en- gage with pinions on a very large pinion shaft to pre- vent any distortion taking place between the two gears. A powerful friction clutch with hand control gives the operator control of the press stroke or movement at all points. Fig. 2 is an illustration of a machine for pressing all parts of automobile bodies, including seats and pan- nels for touring cars. For this reason an unusual amount of die space is provided between the bed and the slide to accommodate the dies required for press- ing up the large steel backs or seats. The stroke is 24 in., and an additional subbase or bed is provided for attachment on top of the main bed. The hight of this subbase is 40 in., so that when it is in position the dis- tance between the bed and the slide is what it is for ordinary work. The same bed plate or bolster which 1s used on the main bed of the press will fit on the sub- 1 09 THE IRON AGE 1927 plate Company, Pittsburgh.

The close of the year witnesses closer co-operation between the sales office and the shop than has pre- vailed at any time since orders began to come in freely.

This is also true of the drawing attachment used in connection with the bed for operating the drawing and forming dies required by this class of work.

Pur- chasers, however, are not always ready to accept ship- ments of machinery promptly, especially where the completion of new buildings or additions has been de- layed, and some sellers have been subjected to con- siderable embarrassment on that account, as it is diffi- cult to hold finished tools or other apparatus in storage awaiting a customer’s convenience, when identical equipment is needed elsewhere. Buyers generally, it is urged, should show a better appreciation of this fact, thereby aiding manufacturers to plan their work and deliveries with some certainty as to what will be satisfactory all around. At present, in particular, it is not easy to learn the customer’s real requirements as to date of installation. Frequently, after first insisting upon delivery within 30, 60 or go days, as the case may be, then requesting delay in shipment (and pay- ment), the purchaser will suddenly order the machine rushed forward, keeping the wires hot until he gets it. All of this shows poor management on somebody’s part.

The spindle and face plate of both work and former heads consist of one solid forging. The heads are heavily constructed to prevent chatter. The cam spindle head is on a cross slide to permit of adjust- ment for depth of cut; a micrometer index permits of very accurate readings. The capacity of the machine ’ Conn. Waterbury, comprises all classes of cams up to 16 in. diameter. There are four cutter speeds and four changes of feed.
