Abstract
Abstract A torque rod of variable length permits use of a torque wrench in confined quarters since the distance between the wrench and unit being tightened may be readily adjusted. A sleeve with a non-circular hollow receives a hollow stem carrying a ball detent which fits into any of a series of depressions in the sleeve wall. Within the stem is a pin with a bevel on its inner end. By moving the stem, the bevel forces the ball in or out to permit the stem to be moved in or out relative to the sleeve. A cam determines motion of the pin.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
209 words
An adjustable length connection for use between a driver member and driven member comprising a hollow sleeve having a non-circular interior and an open second end, the interior of said sleeve being formed with a series of longitudinally spaced depressions, a hollow stem shaped to fit inside said sleeve with a sliding fit and having a closed first end inside said sleeve, a second end external to said sleeve shaped to receive the other of said members, and a first hole formed in the wall of said shank transverse to the axis of said stem spaced from said first end, and an aligned pair of second holes transverse to said axis external to said sleeve, an actuating pin slidable in said stem having a first end formed with a cam surface and a second end formed with a cam follower surface, a detent movable in said first hole, said actuating pin when retracted in said stem forcing said detent outward of said stem and into a selected one of said depressions, a cam pin slidable in said second holes formed with first and second cams engaged by said cam follower surface, said cams controlling the position of said actuating pin relative to said stem between retracted and projected positions.

An adjustable length connection for use between a driver member and driven member comprising a hollow sleeve having a non-circular interior and an open second end, the interior of said sleeve being formed with a series of longitudinally spaced depressions, a hollow stem shaped to fit inside said sleeve with a sliding fit and having a closed first end inside said sleeve, a second end external to said sleeve shaped to receive the other of said members, and a first hole formed in the wall of said shank transverse to the axis of said stem spaced from said first end, and an aligned pair of second holes transverse to said axis external to said sleeve, an actuating pin slidable in said stem having a first end formed with a cam surface and a second end formed with a cam follower surface, a detent movable in said first hole, said actuating pin when retracted in said stem forcing said detent outward of said stem and into a selected one of said depressions, a cam pin slidable in said second holes formed with first and second cams engaged by said cam follower surface, said cams controlling the position of said actuating pin relative to said stem between retracted and projected positions.
Claim 3
Dependent Claim
33 words
A connector according to claim 1 which further comprises a spring in said stem between said inner end and the inner end of said actuating pin biasing said actuating pin toward projected position.
Claim 4
Dependent Claim
19 words
A connector according to claim 1 in which said cam surface is a bevel formed on said first end.
Claim 5
Dependent Claim
19 words
A connector according to claim 3 in which said detent is a ball dimensioned to seat in said depression.
Claim 6
Dependent Claim
30 words
A connector according to claim 1 in which cam follower surface is rounded and said first and second cams are complementary to said cam follower surface and of different depths.
Claim 7
Dependent Claim
34 words
A connector according to claim 1 in which said second end of said stem is formed with a plug, and a detent means in said plug to detachably engage said other of said members.
Claim 8
Dependent Claim
