DEFINITION

Classification: 269/166

(under subclass 165) Device including means to effect an adjustment-lock* which means comprises at least two relatively movable elements with antipodal pairs of mutually abutting surfaces, said surfaces being caused to bind or frictionally engage by relative tilting or skewing of either (1) one of said elements with respect to the other or (2) a third element with respect to both of said relatively movable elements.

(1) Note. Generally, members having a restricted path of movement with respect to each other because of the mating configuration of their inter-engaged parts are cant locked in relative position by moving one member askew to said path of movement.

(2) Note. The use of one or more pivoted elements to effect an adjustment-lock by frictionally engaging a member is not considered to be a "cant lock" mechanism. Such mechanism is a clamp means for subclass 203. The "cant" means of this and

indented subclasses do not have pivots or axes and are free for relative tilting or skewing.

(3) Note. In illustration below the opening 3 in jaw member 1 permits free movement along bar 2 when the jaw member is positioned as shown at B. When canted as shown at A, the jaw member is immobilized. [figure]
