ABSTRACT:
A vehicle jack which may be employed for towing or lifting purposes, as required. The jack incorporates a lifting hook slidably fastened by rachet means to a jack bar fitted with transverse rachet teeth, with a hollow collar fixed at the end of the jack bar of a size to pass about a length of chain. The lifting hook is also fitted with a hole of a size to pass about a length of chain. Together with a removable lift plate, the jack bar and lifting hook may be employed in customary fashion to lift a vehicle by the vehicle bumper. Alternately, a length of chain may be fastened at one end to a fixed object or stake and passed through the collar and lifting hook holes, with a closed loop, fastened to the opposed end of the jack bar fastened about the vehicle bumper for towing purposes. A slidable pin is fitted through a link of the chain to engage the hook teeth, with ratchet movement of the lifting hook resulting in applying tension to the chain and attached vehicle. After the lifting hook has come to the end of its travel on the jack bar, a second slidable pin is fitted through a link of the chain, adjacent to the fixed collar, to hold the chain taut, while the lifting hook is moved in the reverse direction, preliminary to fastening the lifting hook to a chain link for pulling a second length of chain, the length of the jack bar. The chain may be wound on a reel attached to the end of the jack bar.
