Description

March 1951 w. F. DRlTLEY AXLE STUB-REMOVING TOOL Filed Dec. 6, 1946 Patented Mar. 6, 1951 UNITED STATES .E ATENT OFFICE AXLE 'STUB-REMOVING ,TOOL

William. F. Dritley, Benton Harbor, Mich.

Application December 6, 1946, Serial No. 714,570

2 Claims. 1.

This invention relates to gripping tools, and more particularly to a tool for removing broken axle stubs from automotive vehicles.

A main object of the invention is to provide a novel and improved axle-gripping tool which is very simple in construction, easy to use and reliable in performance.

A further object of the invention is to provide an improved axle-gripping tool which is inexpensive to manufacture, sturdy in construction and which may be effectively employed by a relatively unskilled operator.

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein:

Figure 1 is an elevational view of an axle stubremoving tool constructed in accordance with the present invention.

Figure 2 is a vertical longitudinal cross-sectional view taken through the tool of Figure 1.

Figure 3 is a horizontal longitudinal cross-sectional view taken through the tool of Figure 1.

Figure 4 is an end view of the tool of Figure 1.

Figure 5 is a transverse cross-sectional view taken on line 5-5 of Figure 3.

Referring to the drawings, II designates an elongated tubular housing of suitable material such as pipe stock. Slidably positioned inside housing II is a generally cylindrical block or plunger member I2 formed with a longitudinal keyway I3 which slidably engages a lug or key I4 projecting from the inner wall surface of housing II. Threadedly engaging the rear end portion of plunger I2 is a rod member I5 extending rearwardly in housing H and secured to a handle member It rotatably mounted in the rear portion of said housing. Secured in the rear portion of the housing is a pilot screw I! having an inwardly projecting end I8 which is engaged in an annular groove I9 formed in the shank of handle member It for restraining said handle member against longitudinal movement with respect to the housing.

Plunger member I2 carries at its forward end a pair of parallel lugs 20, .29 and pivotally secured to the lugs by respective transverse pins 2I and 22 are a pair of forwardly projecting jaw members 23 and 24 projecting through a diametrical slot 28 in the end wall of housing II and formed with respective serrated gripping fingers and 26. Positioned in opposed recesses formed in the jaw members is a biasing spring '21 which urges the jaw members apart.

When handle member I6 is rotated in one direction, plunger member I2 is moved rearwardly in housing I I, causing the gripping fingers 25 and 26 to be moved closer together, and when the handle member I6 is rotated in the opposite direction, the plunger member I2 is moved forwardly, whereby spring 21 urges the gripping fingers apart.

In operation, the tool is inserted into the axle housing and the gripping fingers 25 and 26 are engaged in diametrically opposite spline grooves in the broken axle stub. Handle member I6 is then rotated to move plunger member I2 rearwardly, and thus tighten the gripping engagement of fingers 2-5 and 26 with the axle. The axle may then be pulled out of the axle housing. To release the broken stub after it has been withdrawn from the axle housing, handle member I6 is rotated in the opposite direction.

The tool may be taken apart by unscrewing pilot screw II, thus allowing the inner parts to be withdrawn from housing II.

The outer diameter of housing II is made less than the maximum outside diameter of an axle so that the tool may be readily inserted in the axle housing. By employing a suitable outer diameter of housing I I, the tool may be employed with a wide range of axle sizes, since handle member I6 may be rotated to adjust the distance between gripping fingers 25 and 26 in accordance with the groove diameter of the axle stub which is to be removed.

While a specific embodiment of an axle stubgripping tool has been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention other than as defined by the scope of the appended claims.

What is claimed is:

1. Gripping mechanism for extracting axle stubs from axle housings comprising a tubular casing having an end wall and a diametrical slot in the end wall, a rod member mounted in said casing for movement forwardly and backwardly, a plunger slidable within said casing and having one end secured to one end of said rod member, a pair of lugs arranged in parallel spaced relation projecting from and fixedly carried by the other end of said plunger, means for preventing rotation of the plunger within the casing and arranged to maintain said lugs parallel to said diametrical slot as the plunger moves slidably within the casing, a pair of jaw members arranged in face-to-face relationship with respect to each other projecting from the end wall of said casing slidably through the diametrical slot interfittingly therewith and pivotally mounted on and disposed between said lugs for movement toward and away from each other, and spring means mounted in the confronting faces of said jaw members and spaced from the pivotal mounting of the latter for biasing the jaw members away from each other.

2. Gripping mechanism for extracting axle stubs from axle housings comprising a tubular casing having an end wall and a diametrical slot in the end wall, a rod member mounted in said casing for movement forwardly and backwardly, a plunger slidable within said casing and having one end secured to one end of said rod member, a pair of lugs arranged in parallel spaced relation projecting from and fixedly carried by the other end of said plunger, said plunger being formed with a longitudinal groove, a lug carried by the inner wall surface of the casing slidably engaging in said groove and so positioned on the wall surface to arrange said lugs in parallel relation with respect to said diametrical slot, 2. pair of jaw members arranged in face-to-face relationship with respect to each other projecting from the end wall of said casing slidably through the diametrical slot interfittingly therewith and pivotally mounted on and disposed between said lugs for movement toward and away from each other, there being opposed recesses in the confronting faces of said jaw members and spaced from the pivotal mounting ofthe latter, and spring means mounted in said recesses for biasing the jaw members away from each other.
