Abstract: Provided is a tensioning clutch to be used in a tool for tensioning bundle, or cable, ties. A tensioning clutch according to the present invention includes a pawl mechanism having a removable pawl insert adapted to be reoriented or replaced without requiring significant disassembly of the housing of the tool. A tensioning clutch according to the present invention includes a pawl link, a tension abutment at least partly contemporaneously movable with the pawl link, and a pawl mechanism movably coupled to the pawl link. The pawl mechanism includes a pawl insert having one or more tie engagement surfaces, the insert being detachably coupled to a pawl body. The tie engagement surface of the insert may be biased towards, and movable away from, the tension abutment.

Abstract: A vertical pull apparatus for converting a vertical pulling motion to a horizontal pulling motion, which vertical pull apparatus typically includes a support for positioning in a generally vertical position. A cable-engaging mechanism is provided on the support, which cable-engaging mechanism engages a cable and defines a generally vertical cable segment and a generally horizontal cable segment in the cable. A first cable-gripping element and a second cable-gripping element on the support alternately and repeatedly grip and release the vertical cable segment of the cable. At least one of the cable-gripping elements is adapted for gripping and pulling the vertical cable segment of the cable along a vertical axis, such that the horizontal cable segment is pulled along a horizontal axis.

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 connecting and tensioning two wires. The device includes two operating members or blocks which are movable back and forth relative to each other in a substantially longitudinal direction. The operating members have gripping portions which coact with the wires to tension the wires upon reciprocal movement of the members. In one embodiment the wires are tensioned in one direction of movement of the members relative to each other and in another embodiment the wires are tensioned in both directions of movement of the members relative to each other.
