UNITED sTATE's PATENT oEFlcE COMBINATION PULLER Ben Pepperdine, Chicago, Ill. Application 'June 23, 1937, Serial No. 149,898 Claims. (Cl. 29-85) The invention relates to improvements in comhexagonal abutment I4 formed on the rod III and bination pullers especially adapted for pulling whereby the ram II may be utilized as a handle grease retainers, truck axles, drive shaft pinions, member to hold the rod I0 against turning when generator pinions, gear sleeves, bushings and desired.

The clamp- 50 threaded on the end of the rod I0 and also coning arms I1 are also reversed in their notches I6 stitutes an abutment against which the ram II so that the rounded cam surfaces 23 are engaged strikes in manipulatingthe puller. At its inner and cooperate with a conical exterior can surface end, the ram II is provided with a hexagonal 21 provided on the manipulatingmember 20 and socket I3 adapted and arranged' to receive a vwhereby the clamping arms I1 may be readily 55 manipulated to engage around a wheeljnut or the like, as will be readily understood by those skilled in this art.

When the clamping arms l'i have thus been engaged with an object to be pulled or removed, the ram H is utilized as a hammer by sliding it on the rod l to strikeagainst the abutment handle l2 thereby imparting shock to the engaged part to facilitate its release and removal.

By this arrangement, a simple and eiective constructionis provided which is capable of being inserted into recesses of considerable depth; which, owing tothe length of clamping arms possible, will have a considerable length of expansion; which, owing to the form of the clamping arms, will be capable of entering and operating in comparatively small recesses and openings; which requires no loose parts or attachments; which may be readily converted to engage either rings or the like and nuts or the like; and which is of simple design and neat in appearance. The specific form and arrangement of parts is a simple and eiective one for the purpose.

While I have illustrated and described the preierred form of construction for carrying the invention into effect, this is capable of variation and modification .without departing from the spirit of the invention. I therefore do not Wish to be limited to the precise details disclosed, but desire to avail myself of such variations and modifications as fall 'Within the scope of the appended claims.

I claim:

1. A device of the class described comprising an operating handle; an operating head on said handle having slots extending therethrough; a clamping arm extending loosely through each of said slots; a. spring carried by, and releasably locking each arm in its slot; and a reversible manipulating member threaded on said handle and having both an interior and an exterior conical cam surface one cam surface and the arms co-operating in a certain arrangement of each to move the arms in one direction and, upon reversal of said arms and manipulating member, the other cam surface and said reversed arms co-operating to move the arms in the opposite direction.

2. A deviceof the class described comprising an operating handle; an operating headon said handle having slots extending therethrough; a clamping arm extending loosely through each of said slots; a spring mounted on one side and there'being a notch in the other side of each arm releasably locking it in its slot; and a reversible manipulating member threaded on said handle and having both an interior and an exterior conical cam surface one cam surface and the arms co-operating in a certain arrangement of each to move the arms in one direction and,

upon reversal of said arms and manipulating member, the other cam surface and said reversed each to move the arms in one direction and, upon reversal of said arms and manipulating member, the other cam surface and said reversed arms co-operating to move the arms in the opposite direction; and a ram slidable on said handle.

4. A device of the class described comprising an operating handle;. an operating head at one end of said handle having three radially arranged rectangular slots extending therethrough; a c'amping arm extending loosely through each of said slots; a spring mounted on one side and there being a notch in the other side'of each arm releasably locking it in its slot; a reversible manipulating member threaded on said handle and having both an interior and an exterior conical cam surface one cam surface and the arms co-operating in a certain arrangement of each to move the arms in one direction and.'

upon reversal of said arms and manipulating member, the other cam surface and said reversed arms co-operating to move the arms in the opposite direction; a ram slidable on 'said handle and having a socket polygonal in cross-section at one end; and a polygonal abutment on said handle engaging said socket.

5. A device of the class described comprising v an operating handle; a plurality of clamping arms reversibly mounted on said handle; and a reversible manipulating member threaded on said handle and having both an interior and an exterior conical cam surface one cam surface anc'- the arms co-operating in a certain arrangemenY of each to move the arms in one direction and, upon reversal of said arms and manipulating member, the'other cam surface and said reversed arms co-operating to move the arms in tne opposite direction.
