Abstract:
A puller tool comprising:an elongated actuating member having a forward end, a rear end, and a longitudinal axis connecting said ends;a finger guide member mounted at said forward end of said actuating member, said actuating member being axially movable relative to said finger guide member;said finger guide member threadably mounted on said actuating member and said actuating member having a handle at said rear end for manually rotating said actuating member to effect said axial motion thereof;a plurality of fingers angularly spaced about said axis and mounted on said finger guide member for radially directed motion normal to said axis, each said finger having a radially inner cam surface and a radially outer wedge surface terminating in a peripheral insertion edge defining a forwardmost extent of said puller tool;said finger guide member having a plurality of radially extending guide channels for receiving and guiding said plurality of fingers;a plurality of spring loaded plungers mounted in said finger guide member for engagement with said fingers to increase frictional resistance to said radial directed motion of said fingers and to prevent said fingers from sliding out of said channels;said actuating member having an engagement head at said forward end arranged to engage said cam surfaces of said plurality of fingers for causing simultaneous radially directed motion thereof incident to axial motion of said actuating member relative to said finger guide member;a slide hammer slidably mounted on said actuating member for axially directing travel therealong, and an impact member fixed at said rear end of said actuating member for impact by said slide hammer to force said puller tool in a rearward axial direction.
