Abstract
Abstract A hand weapon comprising a pair of hollow members which are adapted to be interengaged to form essentially a hollow rod, an elongated flexible member contained within the rod and its two ends being securely fastened within the outer ends of the respective parts of the rod, whereby when only one end of the rod is grasped by hand and swung forcibly about, the other end thereof will slidably disengage and will extend the flexible member to its full length.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
268 words
A hand weapon comprising: first and second generally cylindrical metallic members whose inner ends are slidably interengaged and whose outer ends are dome-shaped and substantially fully enclosed, said members except for said dome-shaped ends being of uniform diameter throughout their length, said diameter being such as to be conveniently grasped by hand, and each of said members being elongated whereby said members together form an elongated rod; one of said cylindrical members having a relatively thin circumferential wall, the other member having a relatively thick circumferential wall whose inner end has a projecting interior flange portion that is slidably received within the inner end of said one member; a pair of fastening pins, one within the outer end of each of said cylindrical members, each said pin extending transversely within the associated member and having its outer ends secured in the outer circumferential wall of the member; and an elongated flexible metal chain whose length is at least twice the length of said rod, the end links of said chain being captured upon corresponding ones of said fastening pins, and said chain occupying the interior space of both of said cylindrical members and being loosely folded up therein; whereby said weapon may be used as a weight for striking purposes by grasping same with one hand near its longitudinal center and using the hand grip to hold said two members together; and whereby, alternatively, the user may grasp one of said cylindrical members only, and swing said weapon about so that the other member slides longitudinally outward and said flexible chain then becomes extended to its full length.
Claim 2
Dependent Claim

A hand weapon comprising: first and second generally cylindrical metallic members whose inner ends are slidably interengaged and whose outer ends are dome-shaped and substantially fully enclosed, said members except for said dome-shaped ends being of uniform diameter throughout their length, said diameter being such as to be conveniently grasped by hand, and each of said members being elongated whereby said members together form an elongated rod; one of said cylindrical members having a relatively thin circumferential wall, the other member having a relatively thick circumferential wall whose inner end has a projecting interior flange portion that is slidably received within the inner end of said one member; a pair of fastening pins, one within the outer end of each of said cylindrical members, each said pin extending transversely within the associated member and having its outer ends secured in the outer circumferential wall of the member; and an elongated flexible metal chain whose length is at least twice the length of said rod, the end links of said chain being captured upon corresponding ones of said fastening pins, and said chain occupying the interior space of both of said cylindrical members and being loosely folded up therein; whereby said weapon may be used as a weight for striking purposes by grasping same with one hand near its longitudinal center and using the hand grip to hold said two members together; and whereby, alternatively, the user may grasp one of said cylindrical members only, and swing said weapon about so that the other member slides longitudinally outward and said flexible chain then becomes extended to its full length.
Claim 3
Dependent Claim
52 words
The weapon of claim 1 wherein said flange has a pair of circumferential grooves formed on its exterior surface, and said weapon further includes a pair of elastomeric O-rings occupying respective ones of said grooves and forming a relatively tight but nonetheless slidable seal with the inner end of said one member.
Claim 4
Dependent Claim
33 words
The weapon of claim 2 wherein the outer end of said flange is chamfered thereby providing a reliable centering action when said flange is inserted within the end opening of said one member.
Claim 5
Dependent Claim
28 words
The weapon of claim 1 wherein the parting line between said two cylindrical members is longitudinally asymmetric, said thin-walled member being of greater length than said thick-walled member.
