Abstract
A clamping collar is provided to be mounted about a shaft, arbor or the like, which may be secured at any position along the longitudinal axis of the shaft and preferably adjacent to the load on the shaft. The device comprises a pair of interfaced rings concentric about the shaft and arcuately shiftable one with respect to the other to shift locking lugs radially into and out of clamping engagement with the shaft. The device also includes means to make lateral pressure contact with arbor spacing sleeves, washers, spacers or flanges assembled on the shaft to space tool means, or the like, therebetween.

A shaft clamping collar comprising:
- (a) a first member adapted to encircle a shaft;
- (b) a second member adapted to encircle said shaft and to interface with said first member;
- (c) means to secure said second member to said first member for relative arcuate shifting therebetween;
- (d) lug means positioned between said first and second members;
- and
- (e) means to radially shift said lug means by arcuately shifting said second member,
- whereby said lug means may be shifted radially to clampingly engage and to disengage said shaft.
A shaft clamping collar comprising:
- (a) a first member adapted to encircle a shaft;
- (b) a second member adapted to encircle said shaft and to interface with said first member;
- (c) means to secure said second member to said first member for relative arcuate shifting therebetween including guide means mounted on said first member and openings provided in said second member to receive said guide means therein to support said second member thereon, said openings being configured to permit arcuate shifting of said second member concentric with said first member;
- (d) lug means interfaced between said first and second members;
- (e) means to radially shift said lug means by arcuately shifting said second member including cam follower means mounted on said lug means and cam means provided in said second member to receive said cam follower means therein, said cam means being configured to shift said cam follower means and said lug means to clamp or de-clamp said shaft when said second member is arcuately shifted;
- and
- (f) means secured to said first member adapted to exert an axial thrust about the periphery of said shaft against an object mounted on said shaft.
