AXLE-CUTTER.

SPECIFICATION forming part of LettersPatent No. 477,268, dated June 21, 1892.I

v Application filed August 3l, 1891..' Serial No. 404,203. (No model.)

To all whom it may concern:

Be it known that we, DAVID E. REED and ORLANDO GURNEE, citizens of the United States, residing at New Hudson, county of Oakland, State of Michigan, have invented a certain new and useful Improvement in Axle- Outters; and We declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying 1c llrawings, which form a part of this specificaion.

Our invention relates to axle-cutters for cutting back the end and shoulder of an axle for the purpose of readjusting the hub on the wheel; and it consists in certain improvements (hereinafter specifically described) for adjusting the axle relative to the tool and in improved methods of feeding the tool.

The special feeding mechanism used we also desire secured to us for use in other combinations than that shown on axle-cutters.

In the drawings, Figure 1 is a perspective of our device. Fig. 2 is a vertical section. Fig. 3 is an end elevation showing method of gripping the axle and means for adjusting it. Fig. et is a view showing details of the external portion of the feeding mechanism.

In the drawings, A is the plate, in which is sleeved the tool-shaft D and feeding-spindle O.

B is the plate, carrying the movable jaws for gripping and holding' the axle. The plates A and B are connected by bolts or rods a2. These bolts may be cut down at each end and provided with right and left screws, respectively, so as to screw the two plates A and B together to make them into one frame-work for supporting the working parts of the machine. On the outer plate B is bolted the lower' jaw B', and which is provided with slotted bolt-holes b for vertical adjustment. To the jaw B is attached the upper jaw B2, the distance between the jaws being regulated by the set-screws b b', thus providing for axles of different sizes. The vertical adjustment of the lower jaw B' permits the axle to be centered with relation to the tool-holder. The sleeve A of thevplate A is provided with an internal thread a. The sleeve or spindle C is provided with an external thread c to correspond and engage with the internal thread in the sleeve and has on each side of i the thread c journal-bearings c and c2, working in corresponding bearings a4 and a5 of the sleeve A.

On the outer end of the sleeve or spindle O is mounted the ratchet-wheel C. Mounted in the sleeve or spindle O is the tool-shaft D, provided on its inner end with a thread to engage the tool-head E and on its outer end with a square end to receive the crank F. Rotary motion to the head Eis given by the crank F, and an endwise movement is given to the tool-shaft I) and the tool by rotating the sleeve or spindle O in the threaded portion of the plate A.

' The tool is provided with an inner bearing which abuts against the inner end of the sleeve C, so that when the sleeve is moved inward, by revolving it in the frame through the operation of the screw it forces the toolhead inward toward the axle'held between the jaws on the plate B.

The means employed by us for automatically feeding the cutter are as follows: On the side of the sleeved portion A' of the plate A, I provide a projection or lug G. In the outer end of this lug is Ithe projecting pin g, on which is mounted a lever g', having a free movement thereon. On the outer end of the arm g is the pawl g2, engaging with the ratchet-wheel O. On the opposite end of the lever g is a rigid pawl or arm g3, adapted to prevent backward revolution of the ratchetwheel after it has been advanced by the pawl g2. The crank F is provided on the end opposite the vhandle f with a pinV f projecting inward from the crank and adapted at each revolution of the crank to strike against the outer end of the lever g and as it passes the end of the lever operate the pawl g2 to move the ratchet-wheel one or more points. The pin f has a slotted connection with the end of the crank-arm, so that it may be moved inward toward the pivot of the crank, and thus strike the lever g nearer its pivot and give the pawl g2 an increased throw, so as to move the vratchet-wheel C any number of points desired within a certain limit. This feeding mechanism just described, with its adjustable feed in the way of the pin having a slotted connection with the crank for adjusting the movement of the pawl, we believe IOO to be new, generally, as well as specifically, in a gear-cutter.

The operation of our device is as follows: The axle to be cut is xed between the jaws B and B2 and is centered relatively to the tool-holder by adjusting the jaw B on the face of the plate B. In the tool-holder are mounted tools e and e in the usual manner, and which may be set the outer one to cut back Ithe shoulder and the inner one to cut off the end of the axle. The ratchet-wheel may now be turned by hand until the tools engage with the axle, and on revolving the tool. holder by means of the crank the feeding mechanism will on each revolution of the crank feed the ratchet-wheel one or more points, and by reason of the threaded c0nnec. tion of the sleeve C with the sleeve portion of the plateA will force the tool-head inward` and cause it to feed or cut away the end of the axle, as desired.

We are aware that it is not new to cut back axles in this manner or to feed the head by means of a sleeved shaft and spindle; but we are not aware that any means have been used for automatically feeding` the tool while cutting back the axle.

We are not aware that the adjustment for the purpose of centering the axle relative to the tool-holder has ever been accomplished by adjusting the jaws on the outer end of the frame in the manner shown and described.

What we claim is- 1. In an axle-cutter, the combination of the plates A and B, the jaw B, having a vertical adjustment on the plate B, and the jaw B2,

adjustably engaged with the jaw B', substantially as described.

2. In an axle-cutter, the combination of a frame, a sleeve having a threaded connection with said frame and adapted to feed forward on being rotated therein, a spindle rotatably mounted in saidsleeve and provided with a tool-head, a ratchet-Wheel on said sleeve, a crank on said spindle provided with an adjustable pin, and a pawl operated by the pin and adapted to rotate said ratchet-wheel and sleeve one or more points on each revolution of said crank, substantially as described.

3. In anI axle-cutter, a feeding mechanism consisting of lever g', pivoted to the frame of said cutter, and pawl g2 and pin f', mounted in the crank of said axle-cutter, substantially as described.

4. In an axle-cutter, a feeding mechanism consisting of lever g and pawl g2, in combination with crank F, and pin f', having a slotted connection with said crank, whereby the throw of the lever g may be increased or diminished,substantially as described.

5. In an axle-cutter, feeding mechanism consisting of threaded sleeve C, ratchet-Wheel C', lever g', pawl g2, rigid pawl g3, and crank F, provided with pin f', substantially as described.

In testimony whereof we sign this specifica tion in the presence of .two Witnesses.
