DEFINITION

Classification: 269/190

(under subclass 189) Device including a tapered or sloped block in the train of adjustment-lock mechanism which block is shiftable to effect binding of relatively movable jaws.

(1) Note. In the illustration shown below the initial rotation of the screw element shifts wedge block 4 causing wedge block 2 to bind against the frame 1 thus immobilizing member 5 (and part integral therewith) with respect to 1 and 6. Continued rotation of the screw effects said movement thereof. [figure]
