JOHN L. MCCLELLAND, OF KALAMAZOO, MICHIGAN, ASSIG-NOR TO AMERICAN SHARP- ENING MACHINE COMPANY, OF KALAMIAZOO, MICHIGAN.

WHEEL FULLER AND THE LIKE.

Application filed September 4, 1924. Serial No. 735,797.

To all whom it may concern.

Be it known that I, JOHN L. MCCLELLAND, a citizen of the United States, residing at the city and county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Wheel Pullers and the like, of which the following is a specifieation.

This invention relates to improvements in wheel pullers and the like.

My improved wheel puller is especially designed for the pulling of motor vehicle wheels from their axles although desirable for use in other relations as in mandrel presses and the like where a threaded shaft or part is operated upon.

The main objects of this invention are to provide an improved wheel puller device for use on threaded axles and the like which effectively protects the same and enables the separation of the wheel from the axle w1th little likelihood of injuring the threads or bending the axle.

Objects relating to details and economies of construction and operation will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described n the following specification. The invention is clearly defined and pointed out in the clalms.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this application, in which:

Fig. I is a side elevation of a device embodying my invention, the same being shown upon an axle.

Fig. II is a transverse section on a line corresponding to line 2-2 of Fig. I.

Fig. III is a longitudinal section on a line corresponding to line 33 of Fig. II, the impact block being shown in full lines.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, my improved wheel puller comprises a body member 1 which is preferably cylindrical and has a polygonal portion 2 adapted to receive a wrench. This is, in practice, preferably formed of machine steel and is case hardened, the case being quite deep, as indicated iy dotted line 3.

This body member has a. central longitudinal bore at at its inner end, the bore being threaded to correspond to the axle or shaft on which it is intended to use the device. At the inner end of this bore and axially aligned therewith is a recess 5 with which is seated the impact block 6, this impact block being of high carbon steel, such as tool steel. This block is of such length that its outer end '7 projects centrally into the bore 4-, overlapping the threads so that when the body member is threaded upon a shaft. it insures contacting of the impact block wit h the end of the shaft.

Thus arranged, the impact block receives the shock of blows when the axle is driven from a wheel, or the thrust strains when placed in a mandrel press so that the threads of the axle are not injured or distorted, and further, the possibility of springing or bending of the axle is minimized.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A device of the class described comprising a cylindrical body member having a polygonal portion adapted to receive a wrench and a central longitudinal threaded bore with a recess at the inner end thereof of less diameter than the said bore, and an impact block seated in said recess with its outer end projecting centrally into the bore, the threads of the bore extending inwardly beyond the end of the impact block, said body member being of machine steel and having a case hardened surface, said impact member being of high carbon steel.

2. A device of the class described co1nprising a body member adapted to receive a wrench and having a threaded here with a recess at the inner end thereof, and an im-.

pact block of less diameter than the threaded bore seated in said recess with its outer end projecting centrally int-o the bore, said body member being of machine steel and having a case hardened surface, said impact memher being of high carbon steel.

3. A device of the class described comprising a body member having a threaded bore with a recess at the inner end, and an impact block of harder material than the body and an impact block seated in said recess member seated in said recess and projecting and projecting centrally into the bore beyond centrally into the bore in overlapping relathe inner end of the thread and in spaced 10 tion to the threads thereof. relation thereto. 5 d. A device of the class described com- In Witness whereof I have hereunto set my prising a body member having a threaded hand. bore with a recess at the inner end thereof, JOHN L. MGOLELLAND.
