Abstract: A clutch including a pawl having a base portion and an arm portion extending from the base portion; a drive disk adapted to be engaged by the pawl; a friction seal adapted to receive the drive disk; a drive retainer adapted to receive the pawl and a biasing spring that is engaged with the pawl and the drive retainer; and a pinion wheel having a plurality of teeth, wherein said pinion wheel is adapted to receive the drive retainer. The teeth of the pinion wheel operatively mesh with similarly designed teeth on a traction drive wheel which is also included in the traction drive wheel assembly. The clutch operates without the need for manual de-clutching and further without the need for the existence of frictional differentials between clutch members, induced through axial pressing together of clutch components by a thrust spring and through different sizes of frictional contact areas.

Abstract: A bi-directional freewheeling clutch suitable for operatively coupling a driven member with a driving member is disclosed. The clutch, which is part of a traction drive wheel assembly included on a self-propelled, walk-behind lawn mower, or other powered implement, comprises a pawl having a base portion and an arm portion extending from the base portion, and further having a neutral, un-extended state and an engaged, extended state relative to the driving member; a drive disk concentric to the driving member and adapted to be engaged by the pawl; a friction seal concentric to the driving member and adapted to receive the drive disk; a drive retainer concentric to the driving member and adapted to receive the pawl and the biasing means; a biasing means engaged with the pawl and the drive retainer; and a pinion wheel concentric to the driving member and adapted to receive the drive retainer.

Abstract: A vibration stabilizer is provided for a power tool such as a sander or the like which has a pivotally oscillating driveshaft for supporting a tool head. The tool is provided with an elongate body having an internal cavity aligned along a longitudinal axis for receiving a drive motor therein. A driveshaft is pivotally supported upon the elongate body rotatable about a pivot axis. The drive motor operatively engages the driveshaft to cause the driveshaft to pivotally oscillate within a limited angular range when the drive motor is energized. Relative vibration between the tool head and the elongate body is minimized by an elastic ring which extends about the driveshaft and is interposed between the tool head and the elongate body. The elastic ring is loaded in compression axially biasing the tool head and the attached driveshaft in a direction away from the elongate body.

Abstract: An adjustable fence for orienting a plate joiner having a body and a rotating generally planar cutter to cut an arcuate slot in a workpiece is disclosed. The fence comprises a base, a handle and a fastening mechanism. The base is shiftably affixed to the plate joiner body and has a planar surface forming a first fence oriented generally perpendicular to the plane of the cutter. The base also has a guideway parallel to the first fence. The handle is movably adjustably affixed to the base and has a grip portion adapted to cooperate with a hand of an operator and a planar surface forming a second fence forming an angle relative to the first fence. The handle cooperates with the base guideway enabling the second fence to be adjusted along a guideway axis parallel to the first fence relative to the planar cutter. The handle is pivotal about a transverse axis parallel to the first and second fences to vary the angle of the second fence relative to the first fence.
