    Abstract: The illustrated embodiment which is in the form of a winch (or hoist) comprises a reel including a spool and embodying a portion thereof through which it may be driven for its raising and lowering functions. The reel mounts in bearing relation to a drive shaft between parallel relatively closely spaced side walls of its housing. This embodiment features an overload clutch including a drive plate mounted for rotation with said shaft within said housing. The drive plate nests within a shallow cup-shaped plate firmly and resiliently coupled by springs, parts of which have an interfit relation with portions of the bounding wall. Upon rotation of the shaft the nature and direction thereof is transmitted through the clutch and successive drive transmission elements to the portion of the reel provided for this purpose.
