Abstract: There is provided a clamp for securing a ladder to an aerial cable such as telephone cable. The clamp includes first and second slots for attaching the clamp to adjacent rungs on the ladder. The clamp includes a locking mechanism, having a swivelable portion so that when the aerial cable contacts the swivelable portion the cable becomes fixed securely to the clamp thus safely supporting the ladder against the aerial cable.

Abstract: This invention relates to a pole gripping assembly for use in stabilizing ladders used to ascend a tree, utility pole or the like. The assembly comprises a yoke member having an arcuate shape which is connected between the side rails at an upper end of a ladder. The yoke member is connected by brackets to the side rails for pivotal movement about a transverse axis so as to pivot at least between a plane common with the lader and a plane perpendicular to the ladder. The assembly further includes a pair of arcuate gripping arms which are pivotally connected to the yoke member adjacent opposite ends thereof. The gripping arms are biased to an open position to receive a pole and pivot to a closed position when a pole moves into a pole receiving space generally between the opposite ends of the yoke member. In accordance with the invention the gripping arms hold the pole in the pole receiving space until the ladder is withdrawn from the pole.
