Total Claims: 7
Claim 1
Independent Claim
99 words
A bucking bar, comprising: toolhead and handle parts secured together and having a low recoil impact absorbing and compressible spacer provided therebetween, said toolhead and handle parts being formed for interfitting engagement and butt end shouldered engagement of the former against the latter, and fastener means extending transversely across and between said toolhead and handle parts for holding said toolhead and handle parts engaged with said spacer and for allowing relative movement therebetween in the impact absorbing compression of said spacer, said toolhead and handle parts having interfitting planular wall surfaces extending longitudinally and said fastener means provided therethrough.
Claim 2
Dependent Claim
99 words
A bucking bar, comprising: toolhead and handle parts secured together and having a low recoil impact absorbing and compressible spacer provided therebetween, said toolhead and handle parts being formed for interfitting engagement and butt end shouldered engagement of the former against the latter, and fastener means extending transversely across and between said toolhead and handle parts for holding said toolhead and handle parts engaged with said spacer and for allowing relative movement therebetween in the impact absorbing compression of said spacer, said toolhead and handle parts having interfitting planular wall surfaces extending longitudinally and said fastener means provided therethrough.
Claim 3
Dependent Claim
138 words
A bucking bar, comprising: toolhead and handle parts secured together and having a low-recoil impact-absorbing and compressible spacer provided therebetween, said toolhead and handle parts being formed for interfitting engagement and butt end shouldered engagement of the former against the latter, and fastener means extending transversely across and between said toolhead and handle parts for holding said toolhead and handle parts engaged with said spacer and for allowing relative movement therebetween in the impact absorbing compression of said spacer, said toolhead part comprising a flat bar stock having one end formed at a right angle thereto and the other end cut at an inclined angle, and said handle part including a planular wall surface receptive of said flat bar stock next thereto and having an undercut shoulder receptive of the angular cut end of said toolhead part therein.
