Abstract
A waste receptacle cam lock with locking projection is provided to prevent the unauthorized removal of the waste receptacle from the mounting and supporting bracket. The cam lock associated with the primary supporting bracket and rotatably mounted from said bracket is spring biased such that when rotated to the position in which it functions as a cam to lock a secondary bracket as attached to the waste receptacle in the lock position, the spring biasing will effect a longitudinal movement of the cam disc and positively cause a projection extending from an edge thereof to interlock with a portion of the primary support bracket. Thus, the cam lock will be positively locked in closed position until such time as an operator with a proper actuating key positively and forceably moves the cam member with its mounting shaft in a longitudinal direction against the spring bias in order to disengage the projection from the bracket support. Then, and only then, can the cam lock be disengaged from the locking position.
