UNITED STATES PATENT OFFICE.

JAMES K. CULLEN AND JAMES W. SEE, OF HAMILTON, OHIO, ASSIGNORS TO l THE NILES TOOL WORKS, OF SAME-PLACE.

LATH E.

SPECIFICATION forming part of Letters Patent No. 312,615, dated rebrua'ry a4, 1885.

Application led Tune 18, 1;?84. (No model.)

To all whom it may concern.-

Be it known that we, JAMEs K. GULLEN and J AMEs W. SEE, both of Hamilton, Butler county, Ohio, have invented certain newr and useful Improvements in Lathes, of which the following is a specification.

This invention pertains to metal-turning lathes; and it relates particularly to lathes intended for operating upon work not permitting convenient driving by means of the usual dogs upon the ends of the pieces being turned. Railroad-car axles, for sufficient length of collar at the end to permit the use of a dog in case it is desired to turn both journals at once.

Car-axles have been turned by means of a driving-gear located midway of the length of the axle, the dog being placed at the midlength of the axle. In such a lathe the axles have to be inserted endwise through the driving-gear, and therefore such lathes were not adapted to operate upon car-axles with the car-wheels secured to them. The central driving-gears of such lathes have been slotted or gapped, and the axle has been inserted sidewise through such gap and rigidly chucked in the driving-gear and its hollow shaft; or thc axle has been supported on the usual centers.

Chucking the rough axle, so as to leave the wheel-flange at liberty to be operated upon by turning-tools, is, in our opinion, entirelyimpracticable, and our experience tells us that to support an axle on ordinary lathe-centers and rotate the same by a dog upon the axle will not permit efficient work to be done upon the peripheries of large and hard car-wheels.

By means of our improvements in axlelathes axles with the wheels upon them mayl be easily inserted in the lathe, the work driven by dogs engaging the car-wheels themselves at a point distant from the center, and the axle so rigidly supported as to permit of the heaviest cuts being taken.

Our invention will be readily understood from the following description, taken in connection with the accompanying drawings, in which Figure l is a front elevation, part section, of a lathe illustrating our improvements; Fig. 2, a vertical section through a head-stock upon the line a; Fig. 3, a vertical section ofl instance, do not have the center stock upon the line b, and Figs. 4 and 5 face views of the driving-gear illustrating modifications. 4

In the drawings, A represents a lathe-bed; B, a pair of head-stocksone upon each end of the bed; C, bearings in the head-stocks adapted to receive the journals of the car-axle or other similar piece of work to be turned; A

D, hand-screws-one in each head-stock-for adjusting the lathe-centers or thrust-bearings; E, the lathe-centers, fitting loosely within the screws D, which are hollow; F, a spherical head upon the rear end of each of tbe centers D, seating in the end of the hollow of th'e adj Listing-screw; G, a centerstock secured to the center of the lathe-bed; H, a tubular spindle journaled in the center stock; I, drivingplates, one secured to each endof the spindle H; J, drivers projecting from the faces of the driving-plates, and engaging a dog upon the work being turned, or ribs of the car-wheel,

or the like; K, a driving-gear secured to the center of the tubular spindle; L, a car-axle in operating position in the lathe; M, car-wheels occupying the usual position upon the caraxles; N, a radial gap in the gear K, for per-y mitting the car'axle or other similar piece to be placed in proper position in the lathe, the gap extending through one side of the drivingplates, and tubular spindle also; O, a gap in the bearing of the center stock, whereby free admission is provided to the interior of the tubular spindle.

In turning car-wheels while upon their axles it is desirable that the axles run upon the axlejournals, and not upon the usual lathe-centers. This supports the work more firmly, and also avoids eccentricity due to untrue centers in the axles. The head-stock bearings C are arranged to open and receive the axle, as clearly shown in Fig. 2. The lathe-centers furnish the thrust-bearings for the axle while being turned, and, being free within their adjustingscrews, are at liberty to accommodate themselves to any eccentricity of the centers in the axles. rIhe lathe is to be fitted with the usual toolcarriages and feeding devices.

S represents th-e usual driving-pinion, and V its shaft, which gives motion to the gear K.

In order that the gap N shall not interfere with the driving of the gear, a second pinion,

T, actuated through an idler, U, may be employed, one pinion driving the gear while the gap is passing the other pinion; or the gap may be provided with a removable patch, l?, as illustrated in Fig. 4; or the gap may be patched by alamina of the gear, as illustrated at Q in Fig. 5, the lamina having a gap Which maybe brought into correspondence with the gap N when it is desired that the gap be open.

Compensating drivers may be combined with the driver-plates, and the drivers at each end of the tubular spindle may be itted with mechanism to equalize them with reference to each other.

A description of the last-mentioned feature is reserved as the possible subject for a future patent.

We make no broad claim to supporting the J AMES K. CULLEN. JAMES WV. SEE. Y
