Abstract: A bevel gear backlash adjusting mechanism is disclosed in which a bevel gear is carried by a bearing and is rotatably carried by a stationary shaft so as to be axially shiftable therewith. The stationary shaft includes a supporting portion carried by the frame of a power tool, the supporting portion having a section slotted at an angle to the axis of the shaft. An adjustable slide is also supported by the frame and extends into the angled slotted section of the stationary shaft with an edge thereof formed as a ramp at an angle corresponding to the angle of the slotted section and in engagement therewith. Motion of the adjustable slide normal to the shaft will influence axial motion of the stationary shaft and the bevel gear carried thereon so as to allow an adjustment of the mesh between the bevel gear and its associated bevel gear.

Abstract: An electronic control board implemented by a printed circuit board is supported on a flexible lens or bezel which may be flexed to allow insertion, so as to be retained. The edges of the bezel are received in the interior periphery of an opening in a support housing, which opening is closed off by the bezel and by a cap which retains the exposed periphery of the bezel in its interior portion. Lugs may extend from the support housing and the cap against the printed circuit board to provide better support. The entire assembly is maintained unitary and retained to a power tool by fastening means such as screws extending therethrough and into the power tool.

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 provided 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.
