Abstract
Abstract A torque-transmitting element, such as a chuck, cam or abutment, to be adjustably mounted on a rotating or fixed shaft has an axial bore of the same diameter as the shaft but with a sectoral zone of larger radius extending over an arc between 90* and 150*. Opposite that zone, a radial bore threaded to receive a setscrew lies in the plane bisecting the arc whereby a tightening of the setscrew wedges the shaft between two arcuate bore portions flanking the sectoral zone.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
150 words
In combination, a shaft of circular cross-section and a torque-transmitting element adjustably mounted on said shaft, said element being provided with an axial bore traversed by said shaft; said axial bore having a sectoral zone, extending over an arc between substantially 90* and 150*, whose radius exceeds that of said shaft and which is flanked by two arcuate bore portions of a radius corresponding to that of said shaft; said element being further provided with at least one generally radial threaded bore lying diametrically opposite said zone substantially in the plane bisecting said arc; a setscrew in said radial bore threadedly engaging same for exerting pressure upon said shaft, thereby wedging the latter between said arcuate bore portions; and a supplemental member detachably secured to an end face of said element and provided with a slot accommodating said shaft, said slot being provided with edges parallel to said bisecting plane.
Claim 2
Dependent Claim
150 words
In combination, a shaft of circular cross-section and a torque-transmitting element adjustably mounted on said shaft, said element being provided with an axial bore traversed by said shaft; said axial bore having a sectoral zone, extending over an arc between substantially 90* and 150*, whose radius exceeds that of said shaft and which is flanked by two arcuate bore portions of a radius corresponding to that of said shaft; said element being further provided with at least one generally radial threaded bore lying diametrically opposite said zone substantially in the plane bisecting said arc; a setscrew in said radial bore threadedly engaging same for exerting pressure upon said shaft, thereby wedging the latter between said arcuate bore portions; and a supplemental member detachably secured to an end face of said element and provided with a slot accommodating said shaft, said slot being provided with edges parallel to said bisecting plane.
Claim 3
Dependent Claim
28 words
The combination defined in claim 1, further comprising a second supplemental member secured to said element and axially spaced from the first-mentioned supplemental member with relative angular adjustability.
