Abstract
Abstract A pin-type connector for interconnecting a pair of members having nominally aligned through-bores without requiring true alignment of the bores including a cylindrical cup-shaped bushing with a discontinuous upstanding wall having a frusto-conical interior surface and a fastener-receiving bore in the bottom of the bushing, the bushing at least partially receiving a pin whose exterior surface is frusto-conical and engages the interior surface of the bushing, with a fastening means being received by the pin through a bore therein. The pin is drawn into the bushing by the fastening means, thereby expanding the wall of the bushing to frictionally engage a bore of one of the members. At least one of the frusto-conical surfaces is slightly eccentric with respect to the longitudinal axis of the element upon which it is formed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
133 words
A pin-type connector for interconnecting a pair of members having nominally aligned through-bores without requiring true alignment of the bores, said connector comprising: a cylindrical cup-shaped bushing element having a bottom and an upstanding wall, said wall being discontinuous whereby the same may be expanded into tight frictional engagement with a bore and having a frusto-conical interior surface; a fastener-receiving bore in said bottom; a pin element at least partially received in said bushing and having a frusto-conical outer surface engaging said interior surface; a fastener-receiving bore in said pin; and fastening means received in said fastener-receiving bores for drawing said pin into said bushing to expand said wall; at least one of said frusto-conical surfaces being slightly eccentric with respect to the longitudinal axis of the element on which it is formed.
Claim 2
Dependent Claim
133 words
A pin-type connector for interconnecting a pair of members having nominally aligned through-bores without requiring true alignment of the bores, said connector comprising: a cylindrical cup-shaped bushing element having a bottom and an upstanding wall, said wall being discontinuous whereby the same may be expanded into tight frictional engagement with a bore and having a frusto-conical interior surface; a fastener-receiving bore in said bottom; a pin element at least partially received in said bushing and having a frusto-conical outer surface engaging said interior surface; a fastener-receiving bore in said pin; and fastening means received in said fastener-receiving bores for drawing said pin into said bushing to expand said wall; at least one of said frusto-conical surfaces being slightly eccentric with respect to the longitudinal axis of the element on which it is formed.
Claim 3
Dependent Claim
23 words
The pin-type connector of claim 1 wherein said fastener-receiving bore in said busing is threaded and wherein said fastening means is a bolt.
Claim 4
Dependent Claim
25 words
The pin-type connector of claim 1 wherein one end of said pin includes a flange for retention of said pin against one of said members.
Claim 5
Dependent Claim
27 words
The pin-type connector of claim 1 wherein said pin has a second, opposed frusto-conical outer surface engaging the interior surface of a second of said cup-shaped bushings.
Claim 6
Dependent Claim
29 words
The pin-type connector of claim 1 wherein each of said frusto-conical surfaces is slightly eccentric with respect to the longitudinal axis of the element on which it is formed.
