Abstract: A tool for the exertion of firm, well-modulated, compressional and shear force, ideally suited to the removal of nutshells by hand. An inclined surface moves alongside another surface, creating a V-shaped gap. Such movement will cause materials to be gripped, rolled, and crushed. This pair of surfaces is curved end-to-end around a central axis so that one becomes a circular cylinder, while the other assumes the form of a spiral curve, either around or within the first. One part rotates in relation to the other upon the central axis. The rotary-drum embodiment comprises a spiral curve (20a), the ends joined by a convex arc (22a), the resulting shape extended to form a cylinder. A web (38) spans one end of the cylinder to form a cup (40). The web serves to retain materials (92) being worked (such as edible nuts), as well as to support a central spindle (42) upon which a drum (22a) is turned by means of a key-shaped handle (46).

A spring carried by the sheath engages the second portion of the guard and biases the guard so that the first portion of the guard is retained but not locked in the recess. To release the blade from the sheath, the thumb of the user presses against a lobe formed in the end of the spring to remove pressure on the second portion of the guard, allowing the first portion of the guard to be moved up the ramp side of the recess and out of the sheath, or, alternatively, the handle may be pulled with sufficient force to overcome the bias of the spring and draw the first portion of the guard up the ramp and thus the blade from the sheath.

Abstract: A guide bar for a chain saw having interior channels for conducting fluid to a nose end of the bar. The channel conducts fluid to the nose end of the bar where a sprocket is rotatably mounted. The sprocket has grooves formed in each side of its body for injecting fluid received from the center channel into the supporting bearing surface in the bore of the sprocket. The grooves are configured to inject fluid to the bearing surfaces regardless of the direction of sprocket rotation. The grooves which have open tops also provide for fluid flow between the side of the sprocket body and the side laminates of the sprocket nose. The grooves also provide an exit for fluid to flow out of the bearing surface as the grooves are positioned opposite the center channel as the sprocket is rotated. The flow of fluid through the grooves into the bearing area and the flow of fluid between the sprocket and the side laminates provides a hydraulic wall to prevent entry of contaminants into the sprocket.
