Abstract
Abstract An adjustable belt assembly, usable with machinery for communicating torque between a plurality of movable members, having mutually, threadedly engageable coupling elements at terminal ends of a disconnected belt. In one embodiment, the coupling elements are wholly confined within the cross-sectional area of the belt material; in another, portions of the coupling elements extend from the belt surface and receive a bolt for closing the ends of the belt.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
193 words
An adjustable belt assembly, usable with machinery for communicating torque between a plurality of movable members, comprising: a belt having a plurality of terminal ends; at least one of said ends having means for engaging coupling means; and at least another of said ends having coupling means for the mating thereof with said engaging means; wherein both said means comprise means for selectively coupling said ends in greater and lesser proximity to each other to effect alteration of a given length of said belt; wherein said belt has a longitudinal axis; said ends have terminal surface and relieved areas formed therewithin along said axis, said areas opening on said surfaces; and said coupling means, said engaging means, are disposed in said relieved areas of said one and said another ends, respectively; said relieved areas define circular bores each having a given major cross-sectional diameter; and said coupling and engaging means each comprise inserts having a major cross-sectional diameter slightly greater than said given diameter; and wherein said inserts have circumferential ribs and grooves formed in the external surfaces thereof to effect a restrained engagement of said external surfaces with surfaces of said bores.
Claim 2
Dependent Claim
193 words
An adjustable belt assembly, usable with machinery for communicating torque between a plurality of movable members, comprising: a belt having a plurality of terminal ends; at least one of said ends having means for engaging coupling means; and at least another of said ends having coupling means for the mating thereof with said engaging means; wherein both said means comprise means for selectively coupling said ends in greater and lesser proximity to each other to effect alteration of a given length of said belt; wherein said belt has a longitudinal axis; said ends have terminal surface and relieved areas formed therewithin along said axis, said areas opening on said surfaces; and said coupling means, said engaging means, are disposed in said relieved areas of said one and said another ends, respectively; said relieved areas define circular bores each having a given major cross-sectional diameter; and said coupling and engaging means each comprise inserts having a major cross-sectional diameter slightly greater than said given diameter; and wherein said inserts have circumferential ribs and grooves formed in the external surfaces thereof to effect a restrained engagement of said external surfaces with surfaces of said bores.
Claim 3
Dependent Claim
23 words
An adjustable belt assembly, according to claim 1, wherein: said both means further comprise means for wholly decoupling said ends from each other.
Claim 4
Dependent Claim
27 words
An adjustable belt assembly, according to claim 1, further including: clasp means for enhancing a retention of said engaging and said coupling means in said relieved areas.
Claim 5
Dependent Claim
28 words
An adjustable belt assembly, according to claim 1, wherein: said belt has a given cross-sectional area; and said engaging and coupling means are wholly confined within said area.
Claim 6
Dependent Claim
101 words
An adjustable belt assembly, according to claim 1, wherein: one of said inserts comprises a split housing; said housing defining a shouldered cavity therewithin which is open at one end thereof on said terminal surface; and including a headed bolt rotatably secured in said cavity and extending outwardly therefrom in projection from said terminal surface; said bolt having a radial wheel with a discontinuous circumferential surface for facilitating rotation of said bolt to effect a threaded engagement of said bolt with another of said inserts and relative movement of said one insert with respect to said another insert along said axis.
Claim 7
Dependent Claim
15 words
An adjustable belt assembly, according to claim 5, wherein: said inserts are formed of plastic.
Claim 8
Dependent Claim
78 words
An adjustable belt assembly, according to claim 1, wherein: said inserts each have portions thereof which extend perpendicularly from said axis, and project beyond a given surface of said belt; one of said inserts having a threaded borehole formed in the extending portion thereof; and another of said inserts having an unthreaded borehole formed in the extending portion thereof; said unthreaded borehole carrying a bolt in penetration thereof for threaded engagement of said bolt with said threaded borehole.
