Abstract
Abstract A tool for imparting force to a mechanical element located in a confined area having an impact member for receiving and transferring force applied to it, an end member engageable with the mechanical element, and a connector rotatably joining the end member and the impact member, the end member and the impact member having mating faces at least one of which lies in a plane oblique to the force transmitting axis thereof for applying a force to the mechanical element from an angular position of the impact member relative to the end member by selective relative rotation of the impact member and the end member.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
134 words
A tool for imparting force to a mechanical element located in a confined area comprising, an impact member for receiving and transferring force applied thereto, an end member having a tapered recess in an outer end thereof engageable with the mechanical element, said end member and said impact member having mating faces at least one of which lies in a plane oblique to the force transmitting axis thereof for applying a force to the mechanical element from an angular position of said impact member relative to said end member by selective relative rotation of said impact member and said end member, and a coil spring connector engaging and rotatably joining said end member and said impact member and maintaining said mating faces of said end member and said impact member in force transmitting engagement.
Claim 2
Dependent Claim
134 words
A tool for imparting force to a mechanical element located in a confined area comprising, an impact member for receiving and transferring force applied thereto, an end member having a tapered recess in an outer end thereof engageable with the mechanical element, said end member and said impact member having mating faces at least one of which lies in a plane oblique to the force transmitting axis thereof for applying a force to the mechanical element from an angular position of said impact member relative to said end member by selective relative rotation of said impact member and said end member, and a coil spring connector engaging and rotatably joining said end member and said impact member and maintaining said mating faces of said end member and said impact member in force transmitting engagement.
Claim 3
Dependent Claim
31 words
A tool as set forth in claim 1 wherein said impact member and said end member have passages and said coil spring connector is a cylindrical configuration accommodated in said passages.
Claim 4
Dependent Claim
46 words
A tool as set forth in claim 2 wherein the passages in said impact member and said end member have recesses therein and said spring has catches for engaging said recesses and moving therein during the relative rotation of said impact member and said end member.
Claim 5
Dependent Claim
29 words
A tool as set forth in claim 3 wherein said catches are radially extending convolutions of said spring which engage the recesses which are enlarged bores in said passages.
Claim 6
Dependent Claim
19 words
A tool as set forth in claim 4 wherein the outer diameter of said spring frictionally engages said passages.
Claim 7
Dependent Claim
38 words
A tool as set forth in claim 4 wherein said recesses are spaced a distance such that when said mating faces are in engagement and said catches are engaged in said recesses said spring is maintained in tension.
Claim 8
Dependent Claim
33 words
A tool as set forth in claim 1 wherein both of the mating faces of both said end member and said impact member lie in planes oblique to the force transmitting axes thereof.
Claim 9
Dependent Claim
32 words
A tool as set forth in claim 7 wherein said mating faces are oriented at an angle of approximately 10° with respect to a plane perpendicular to the force transmitting axes thereof.
Claim 10
Dependent Claim
41 words
A tool as set forth in claim 1 wherein said impact member and said end member have passages which are aligned by said coil spring connector such that the shank of another tool element is insertable within said coil spring connector.
Claim 11
Dependent Claim
47 words
A tool as set forth in claim 9 wherein the shank of another tool element is of substantially lesser diameter than the inner diameter of said coil spring connector to permit the angular positioning of said impact member and said end member with the shank inserted therein.
