This invention relates to a pin and bushing removing tool and especially to a device of this character which is particularly intended for use in'removing king pins and their bushings fromthe front axles of automobiles but it is understood, of course, that a tool inaccordance with this invention may be used for any purpose and in any manner for which thesame may be found adapted.

lo and desirable.

An important object of the invention is to provide, in a manneras hereinafter set forth, a tool of the character described embodying a novel construction and arrangement of parts whereby said tool may be expeditiously adjusted for use on the different axles which may be found in various makes of automobiles.

@ther objects of the invention are to provide a pin and bushing removingtool of the character set forth which will be simple in construction, strong, durable, efficient and reliable in use and which may be manufactured at low cost. I All of the foregoing and still further ob jects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the ac companying drawings wherein like charac- 39 ters of reference designate corresponding parts throughout the several views, and

wherein Figure 1 1s a view principally in side elevas tion and partly broken away in vertical longitudinal section showing a tool in accordance with this invention mounted in operative position on an angle.

Figure 2 is a view in vertical section through the axle taken substantiallv on the line 2-2 of Figure 1 looking in the direction indicated by the "arrows and showing the tool in end elevation.

Referring now in detail to the drawings, it will be seen that the reference numeral 1 designates a beam having-a ratchet bar 2 disposed for vertical sliding movement through one end portion thereof, said ratchet bar having a yoke 3 on its upper end for engagement with the axle 4. A keeper 5 is slidably mounted on the beam 1 and is yieldingly 1931. Serial No. 530,675.

The: otherend of the-ubeain. 1 is. suspended from the axle L through. the medium of a s5 hanger which is designated generallyrby the reference. numeral 6 and which? comprises: a pair of spaced, parallel barsT-having removable'pinsBv-andQ extending between the upper and-slower end portions thereofrespecto tivel-y; Rollers 11 having tapered or=conical innerzportions arej ournaled on: the pin '8 and rollers. 11 are j ournaled :on: the lower pin-9, the :rollerson the-upper pin being adapted: for

It is believed that the many advantages of a pin and bushing removing tool constructed in accordance with this invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in details of construction may be had in the combination and arrangement of parts which will fall within the scope of the invention as claimed.

What is claims is 1. A pin and bushing removing tool comprising a supporting hanger including a pair of spaced, parallel bars for disposition on opposite sides of a support, removable pins extending between the end portions of the bars, a fixed pin extending between intermediate portions of the bars, substantially conical pairs of rollers journaled on the first named pins, between the bars, the rollers constituting each pair having their small ends disposed adjacent each other, the rollers on the uppermost pin being adapted for rolling contact with the support, a beam slidable between the bars on the lowermost rollers, a jack screw threaded through one end portion of the beam for engagement with the pins and bushings, and means adjustably mounted on the other end portion of the beam and engageable with the support in a manner to retain the beam against swinging movement on the lower rollers when the jack screw is actuated.

2. A pin and bushing removing tool comprising a beam, means for mounting said beam on a support, said means including a pair of spaced, parallel bars extending on opposite sides of the support and the beam, pins exed on one end portion of the beam, and means on the other end portion of the beam en ageable with the support for retaining the am against swinging movement when the jack screw is actuated.

In testimony whereof I afiix my signature.

tending between the bars above and below the support and the beam respectively, said bars being slidable on the pins, rollers journaled on the pins and engageable with the upper side of the support and the lower side of the beam, a clamping screw extending through intermediate portions of the bars for clamping said bars against the support and the beam, a ack screw threaded through one end 7 portion of the beam for operative engagement with the pin or bushing to be removed, and means on the other end portion of the beam engageable with the support in a manner to prevent swinging movement of the beam toward said support.

3. A pin and bushing removing tool comprising a hanger including a pair of bars, a roller journaled transversely between the bars for rolling contact with a support, another roller journaled transversely between the bars in spaced relation to the first named roller, a beam operable between the bars on the second named roller, a jack screw operatively mount-
