Abstract
This invention relates to a reversible hand operated device having equal utility as a hoist, winch or puller. It features a unique finger operated control housed in an opening of the operating lever of said device, which control may be smoothly shifted from one position to another to dictate either the raising or lowering function of the device as a hoist or an application of tension to or a release of tension from an applied load when the device is used as a winch or a puller. Preferred embodiments of the invention also feature a strong light weight frame comprised of opposed plates the major extent of which are held in a spaced parallel relation by reason of their adjacent ends being turned over, overlapped and simply interconnected to form flats to either end of the frame. The frame is distinguished by bridging pivot means one of which mounts the cable drum and operating lever of the device and another of which pivotally mounts a retainer pawl for engagement with a ratchet in connection with the drum. The invention also illustrates improved let down mechanism selectively governed by a simple slide, the position of which dictates the increment of let down on each cycle of the operating lever of the device.
