BELT SANDER ABSTRACT A stationary or bench mounted belt sander is described constructed of a die cast bed or frame rotatably supporting a drive roll or pulley at one end thereof and provided at the other end portion thereof with generally longitudinal ways for slidably supporting a pair of generally parallel spaced apart outwardly extending generally elongated U- shaped stamped metal yoke or support bracket members pro- vided at their inner or proximal end portions with camming surfaces. The distal ends of the yokes carry pins generally perpendicular thereto supporting a shaft for an idler roll or pulley. The bed or frame is also provided with trans- verse ways carrying ramp elements engaging the camming sur- faces of the yokes, with the ramp elements being provided with transversely outwardly extending screws for cooperation with a nut or internally threaded knob members to pull the ramp members transversely outwardly to thereby cam the yokes longitudinally outwardly for tensioning and tracking adjust- ment of a sanding belt passed about the drive and idler pul- leys. An extension spring spans the bed between the ramp members and the bed, between the pulleys defines a platen. Locking means may also be provided for locking the yokes positively in position.
