Abstract: A tool for applying a force to a chain. The tool comprises a lever and an attachment member pivotally connected to the lever with two opposed arms pivotally mounted to the lever on opposite sides of the attachment member. Each arm has an end adapted to releasably engage and hold the chain. There is a linkage between the arms to guide movement of the arms upon reciprocal pivotal movement of the lever with respect to the attachment member. The arms are operable in a cycle in which one of the arms is maintained stationary to engage and hold the chain while the other arm is released from the chain and moved parallel to the chain past the stationary arm to engage and hold a new location on the chain whereupon each arm assumes the role of the other arm to repeat the cycle. The tool provides a simple and reliable manually operated device for applying a force to a chain. Mounting a weight to the attachment member allows the tool to be used to lift the weight along a suspended chain.

Abstract: A device for gripping or locking a rope or wire comprises a pair of rope engaging members or jaw members defining a pair of oppositely arranged wire engaging surfaces forming a passageway for the rope. The jaw members are mounted in the frame of the gripping device by means of a swinging link suspension including a pair of swinging links. The jaw members are suspended so that the frictional forces acting between the rope and the jaw members cause displacement of the rope engaging surfaces thereon in mutual parallel relationship towards each other, when a pulling force is applied to the rope in a first direction, while the rope engaging surfaces are displaced away from each other, when a pulling force is applied to the rope or wire in a second opposite direction. This means that the rope is pinched between the rope engaging surfaces, when the rope is pulled in the said first direction, and released, when pulled in said second direction.
