Abstract
Abstract An extendible finger wrench comprising a base member which is elongated, rigid and arcuately curved to conform to the pad side of a finger and has elongated side channels, and a set of interchangeable tool holding members which are rigid, elongated and similarly curved and whose side edges slide into the side channels of the body member. Each tool holding member mounts a different tool at its forward end. Resilient means on the curved surface of the base member hold the tool holding member at any point along the length of the base member, and interacting stop members on the base member and tool holding members allow the tool holding member to extend up to 3/4 of its length beyond the base member to extend the reach of the finger wrench.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
243 words
A tool set adapted to be used for removing and replacing connections in areas of limited accessibility comprising an elongated transversely arcuate rigid base member with side channels extending along both elongated edges, first stop means on the base member near its forward end, and a set of interchangeable tool carrying members each adapted to be carried individually on the said base member and comprising an elongated rigid member concentrically arcuate with the base member so as to be able to slide onto the base member with the side edges of the tool carrying member slideably engaged within the said side channels, a second cooperating stop means near the back end of the tool carrying member, a different tool element mounted at the forward end of each tool carrying member, the said first stop means and the said second stop means adapted to abut when the base member and the tool carrying member are at their maximum extension, frictional gripping means on the base member to hold the tool carrying member at any point along the length of the base member so as to provide a tool of optionally varying length, said frictional gripping means comprising a bowed tension spring extending parallel to the length of the base member and secured to it at each of its ends, said spring having an opening at one end to allow room for the flattening of the spring when the tool carrying member rides over it.

Claim 3
Dependent Claim
36 words
A tool set as defined in claim 1, wherein the said tool element mounted at the forward end of each tool carrying member is from the class of wrenches including hex, socket, screwdriver and nut holder.
Claim 4
Dependent Claim
42 words
A tool set as defined in claim 1 wherein the first stop means comprises a bump on the convex surface of the base member, and the second stop means comprises a detent depending from the concave surface of the tool carrying member.
Claim 5
Dependent Claim
61 words
A tool set as defined in claim 3 wherein the bump on the convex surface of the base member is approximately 1/4 the length of the base member from its forward edge to provide an overlap at maximum extension so that the tool will remain sturdy and rigid, and the said detent depends from the rear of the tool carrying member.
Claim 6
Dependent Claim
22 words
A tool set as defined in claim 1 wherein the base member is provided with a clearance opening at its forward end.
Claim 7
Dependent Claim
