Abstract
A yarn package holder device (10) is disclosed which includes a bracket plate (12) adapted to be mounted to a supporting structure (14). A circular cam (A) is rotatably journaled in the bracket plate and is eccentrically connected to a shaft (24) having a remote end affixed to an actuator lever (30) and handle (32). The actuator lever rotates the cam (A) and moves a cam surface (22) in an eccentric path. On the eccentric path, the cam surface (22) includes a lock position with the actuator lever (30) in a down set position. Lifting the actuator lever from the down set position quickly releases the cam lock provided between the cam surface (22) and a ribbed clamping surface (34) permitting rapid removal of an empty tube (38) from which a yarn package (40) has been withdrawn.
