ABSTRACT:
A safety clamp slidably mounted on a vertical safety carrier, such as a cable or rod, in proximity to a ladder is attached to a workman's belt by a pivotal actuating arm which shifts a wedge plate into clamping engagement with the safety carrier immediately under free-fall conditions encountered if the workman falls from the ladder. Instantaneous actuation of the wedge plate into clamping engagement with the safety carrier in response to the slightest pivotal movement of the actuating arm towards its closing position is provided by cam action exerted against the wedge plate by the actuating arm and by a cam member on the clamping bracket. Cam follower and guide surfaces on the upper end of the wedge plate cooperate with camming action of the actuating arm against the lower end of the wedge plate to maintain the wedge plate in an upright position of uniform contact with the safety carrier.
