DEVICE FOR TIGHTENING CHAINS AND THE LIKE Abstract of the Disclosure A device for tightening chains, cables or ropes is disclosed. Previously, turnbuckles or load binders, the latter operating on the principle of the lever, have been used to tighten two ends of a chain or cable around an object, or the ends of two chains which have been secured at their other ends. Such devices are hand- operated and accordingly can only apply limited tension to the chain or cable. The present invention provides a device whereby an air-gun or pneumatic wrench or other power tool can be used to tighten the chain or cable to much greater tension. The device utilizes a threaded bolt which is secured to one end of the chain and which, by the rotation of a threaded socket, is drawn through a sleeve to which the other end of the chain is secured, thereby tightening the chain.
