UNTTED STATES4 PATENT EDWARD BENNETT SAINSBURY, OF CARACAS, VENEZUELA.
CRANK-PlN-TURNING MACHINE.
sPnorFIoATIoN forming part of Letters ratent No. 632,150, dated August 29, 1899.
Application filed October 22, 1898. bSerial No. 694,320. (No model.)
To all whom zt-may concern:
Be it known that LEDWARD BENNETT SAINs- BURY, a subject of Her Majesty the Queen of Great Britain, residing at Caracas, in the Federal District of the United States of Venezuela, have invented a new and useful Crank- Pin-Turning Machine, of which the following is a specication.
My invention relates to an improved machine for turning, truing up, and polishing worn or cut pins without the necessity of removing the same from the cranks or Wheels in which they are fixed; and the objects of my invention are, first, to eect the more rapid and perfect turning or truing up of a Worn pin by the use of a rotary tool o r milling cutter; second, as considerable difliculty has al- Ways been experienced in truing up a pin previously case-hardened to provide for the truing up of a pin so hardened or tempered without annealing the same and to effect the proper finishing or polishing of apin already turned by means of a Wheel or disk of emery or other grinding or polishing material revolving on its own center and simultaneously around the periphery of the pin to be trued up or polished, and, third, to provide a frame which although portable and capable of be- .y ing bolted to the frame of a stationary engine is at the same time rigidand when bolted to a xed foundation-plate constitutes a machine which is self-contained and which also allows of the rapid and perfect adjustment of the tool in any direction. I attainthese obljects by the mechanism illustrated in theacfcompanying drawings, in which- Figure l is a front elevation of the machine with foundation-plate removed; Fig. 2, a top View showing the machine centered with respect to the pin to be turned. Fig. 3 is a` cross-section of a part of the machine on the line l 2, Fig. l; and l and 2, Fig. 4, are end views of foundation and angle plates to which the machine is bolted when in use.
Similar letters and figures refer to similariV rest is provided with the slottedlugs ct for the purpose of bolting the machine to the hand.
foundation or angle plate l 2, Fig. 4, as described hereinafter.
At the end of cross-rest B is a heavy bearing C, in which revolves the head D. I prefer to have this bearing conical, as shown in Fig. 3, with plate E and set-bolts c to take up wear.
In slot d, passing through the' head D, are iitted two sliding blocks F F'. Revolving in these blocks in suitable bearin gs and provided with adjusting-nuts g g are the shafts G G. The plates or washers f f', in conjunction with bolts b, serve to take up Wear of blocks and also to retain the same in a fixed position while taking a cut.
On the end of shaft G is mounted a millingcutter H and on shaft G an emery-wheel I or a disk of similar material. For ordinary purposes I employ a pair of sliding blocks and shafts, as herein described and illustrated. I, however, anticipate the necessity of sometimes using a single block and shaft, mounting the milling-cutter and emery-'wheel alternately, as may be necessary. The sliding block F is provided with a screw h, placed far enough out of center to avoid contact with -the shaft G, the object of which is to advance to the cutter, wheel, or disk by means of' either a flexible shaft, endless rope, or gut band passing over an intermediate idler-pulley for taking up the slack as the head D revolves, or, where there is no steam-power, by In either case the flexible shaft, the pulley for rope-gear, or the crank for handpower is attached to the other end of the shaft on which is mounted the tool it is desired to drive.
The rotary motion of the head D, or what is practically the automatic feeding of the machine, may be effected in several Ways.
IOO
a calso The method I adopt is illustrated in Fig. 2, where the annular plate E is seen to perform a double function-that of taking up wear and keeping head D in its place and, beingcast with the teeth c on its outer face, it consti tutes practicallya circular rack in which the feed-gear of the machine acts. On each shaft is a screw-Worm L L. (Shown in Fig. 3.) Spindle K is supported by two small brackets 7c 71:', bolted to head D. Pinion M is a sliding fit on the spindle to allow of its gearing with either Worm and has a set-screw for retaining it in the required position. The pinion N is a revolving fit on the end of the spindle and is providedwith the thumb-nut and friction-Washer n, allowing it to betightened up or slackened off, as desired. The intermediate pinion O, gearing into the pinionN and fixed wheel or circular rack e, gives the required rotary motion to the head D and with it the cutter H and disk I.
My method of Working the machine is as follows: For locomotive work on a suitable foundation I secure the foundation-plate 1, Fig. 4:, by the side of the rail or pit in the repairing shop and run the engine alongside of it. Ithen bolt the machine to the foundationplate,which is provided for the purpose with inverted-T-shaped slots, as shown. I next turn the Wheel, with the Worn pin, to a convenient position and center the machine by means of compound slide-rest A and the aid of center J, as shown in Fig. 2. Ithen advance the milling-cutter until it touches the most Worn part of the pin and attach the driving power, as heretofore described, and as the cutter revolves I cause it to travel simultaneously around the pin by means of the feed-gear, as heretofore shown. When the pin is only slightly worn or has been previously case-hardened, I dispense with the use of the cutter and employ only the emerywheel, which I also use for polishing a pin turned by the milling-cutter.
For turning up a pin on a stationary engine the machine is bolted to the frame of the engine by means of the angle-plate 2, Fig. 4. In certain cases, such as where there isinsuflicient space or where itis inconvenient to place the entire machine, the arm E may also be dismounted from the slide-rest and bolted or otherwise secured to or in the vicinity of the work to be manipulated. The cutter or disk need not be the exact width of the journal of the pin to be trued up. In many cases it will be found advantageous to have them only one-half or less and to take two or more cuts as required. It will also be evident that by removing the center J and nut j the machine may be utilized for a variety of other Work, such as the turning of journals on shafts, (be.
