Description: |
| Abstract:
This invention relates to frictional clutches and more particularly to those adapted for heavy service such as farm machinery operated by gas engines. Machinery of this and analogous types which is produced at comparatively low cost is in consequence somewhat rough and heavy but primarily it must be strong and durable as it is subjected during usage to heavy strains and while being transported about is exposed to all weather conditions.
Claim:
A clutch comprising a drive member, a driven member, an expanding friction shoe rotatable with one of said' members, said, shoe consisting of a unitary piece formed to provide a hub, a web projecting radially therefrom, and a pair of arcuate arms integral with and extending in opposite directions from said web and adapted by reason of their resiliency to be expanded into frictional engagement with the other clutch member, the opposite ends of said arms being provided with opposed converging faces, a member slidable axially of and rotatable with said friction shoe, a pair of jaws pivotally mounted on said member and having their free ends disposed between the opposed ends of said arms, adjustable means connecting the free ends of said jaws whereby the distance between the jaws may be regulated, and means for moving said jaw-carrying member axially of the clutch to expand the arms of said friction shoe. |
