L. O. B EARD AXLE FULLER Filed June lO 1935 Patented May 8, 1934 UNITED STATES PATENT OFFICE 1 Claim.

My invention relates to tools for pulling axles from their bearings in motor cars and the general object of the invention is to provide a simply constructed and eflicient tool for this purpose.

Other and more specific objects and advantages of the invention will be apparent as the specication is considered in connection with the accompanying drawing, in which:

Figure l is a plan View of the tool;

Figure 2 is an enlarged plan view of the tool partly broken away and partly in section; and

Figure 3 is an end View.

Referring more particularly to the drawing 1 denotes the tool including an elongated cylindrical body portion or mandril 2 of steel or other suitable material. The inner end of the body 2 is serrated to provide a good gripping surface or handle 3. A nut 4 adjacent the inner end of handle 3 serves as a stop for a shocker or rammer member 5, mounted for reciprocatory movement upon the body 2. This member 5 which is made of heavy strong material such as steel and weighs approximately five pounds is formed with a central bore 6 for the reception of the body 2, and like handle 3 is serrated to provide a secure gripping surface.

The outer end of body 2 is externally threaded as at 7 for screw connection with the inner end of an internally threaded adapter member 8, the outer end of which is adapted to be screwed upon the reduced outer threaded end 9 of an axle 10. Wrench engaging portion 11 on the outer end of Ithe adapter facilitates connecting the latter to 5 the axle and to body 2.

In practice the operator after connecting the tool to the axle to be withdrawn from its housing or bearing, grasps the handle 3 with one hand and reciprocates the rammer 5 with his other hand, against the stop nut 4. This is continued until the axle is shocked loose.

The tool is preferably provided with several interchangeable adapters the outer internally threaded ends of which are of different diameters to t axles of varying size.

The adapter is preferably made in two parts, the wrench engaging portion 11 from which a threaded plug 12 extends, and a sleeve 13 threadedly connected to the plug. This permits of the wrench engaging portion being turned for connection with the end 9 of the axle without the necessity of turning the body of the tool. Of course the adapter could be made in one piece, in which case the plug 12 would be omitted.

Having thus described my invention, what I claim is:

An axle pulling tool comprising a body portion,

a handle and stop member on one end of said body, an adapter including an internally threaded sleeve connected at its inner end with the 30 other end of said body, said adapter also including a nut member adapted to be connected at one end to the reduced threaded end of an axle and having a threaded plug extending from the other end thereof for threaded engagement with the outer end of said sleeve, and a heavy impact member slidably mounted on said body for engagement with said stop.
