Abstract
Abstract A nail puller defines an elongated body having a static gripping jaw formed therein and a handle socket for receiving a handle. An elongated handle is threadably received within the handle socket. A moveable jaw is pivotally attached to the puller body and defines a jaw blade and an extending lever arm. A limit stop is interposed between the lever arm and the puller body to provide a limit on the closure of the static and moveable jaws. The puller body further defines a drive receptacle for receiving a drive portion of a lever-type tool such as a drive ratchet as an alternative for the handle. In an alternate embodiment, an additional handle socket is defined by the puller body having an angular orientation different from the first handle socket permitting the use of the removeable handle in alternate configurations.

Total Claims: 11
Claim 1
Independent Claim
221 words
For use in removing an elongated object partially embedded in a body having a surface such that an extending portion of said elongated object extends beyond said surface, a puller comprising: a puller body having a first jaw; a second jaw having a lever arm defining a notch surface; pivot means joining said first and second jaws in a pivotal attachment in which said second jaw is movable with respect to said first jaw and said first and second jaws may grasp said extending portion of said elongated object; handle means coupled to said puller body such that force applied to said handle means in a first direction causes closure of said first and second jaws; and limit means interposed between said puller body and said lever arm for limiting closure of said first and second jaws at a predetermined jaw separation, said limit means including a threaded limit aperture within said puller body and an elongated limit stop having a first end and a threaded second end, said second end being threadably received within said threaded limit aperture and said first end abutting said lever arm at said notch surface, said puller being operative by placing said lever arm against said surface and positioning said first and second jaws on opposed sides of said extending portion of said elongated object.
