摘要： A power tool for trimming soft materials has a power driver with a drive train engaged with a cylindrical cutter body wherein the power driver rotates the cutter body about its longitudinal axis. A plurality of mutually spaced apart cutter teeth are fixed to an exterior surface of the cutter body. The cutter teeth each have a top surface and a sidewall surface, the sidewall surface extensive between the top surface and an exterior surface of the cutter body. The top surface of each of the cutter teeth is a four-sided convex polygon and the sidewall surface includes four mutually discrete surfaces corresponding to the sides of the polygon, with each of said discrete surfaces extending between the top surface and the cutter body.

摘要： A manually portable rotary debris remover, particularly adapted for clearing tree planting sites, has a remotely mounted, power driven, rotating hub on an extended support, such as a chain saw blade. The rotationally driven hub has a plurality of pairs of coiled tine members, each pair radiating out from a respective tine shaft mounted in the hub equidistantly from the hub axis. The tine shafts are each inclined from 3 to 10 degrees from perpendicular to the plane of rotation of the hub, so that, in rotating, the tines of each pair do not simultaneously strike objects in the path of rotation of the tines when clearing debris.

摘要： An adapter having particular application to quickly and easily convert a portable worm driven circular power saw into a sprocket driven chain saw. The adapter comprises an adjustable compression ring portion which is adapted to be attached to the existing bearing plate of the circular saw without requiring a removal of the bearing plate. Coextensively formed with the adapter compression ring portion is a base portion having a structure which permits a cutting chain bar and a cutting chain safety guard to be connected to opposite faces of the base portion. Thus, a circular cutting blade may be replaced by a cutting chain, and vice versa, without removing the existing bearing plate, as is commonly required when a conventional converison apparatus is utilized.

摘要： An attachment for greatly increasing the versatility of a conventional chain saw is capable of being mounted to a wide variety of chain saw models. The attachment is mounted to the chain saw in place of the usual chain bar. The attachment includes a rotatable spindle which may be driven through a roller chain or a V-belt drive. The spindle is adapted to drive tools such as abrasive wheels and drills. The attachment includes a housing which pilots and holds such equipment as water pumps, the impellers of which are rotated by the attachment spindle. The invention includes a sliding guard to which is mounted a chain tightening device. The guard is secured at a location which depends on the chain saw housing size so as to permit the adjustment device to bear against the chain saw housing, thereby imparting controlled tension to the driving chain or belt.

摘要： A portable log splitter having a hydraulic cylinder for applying force to a log wherein the source of hydraulic fluid is a pump driven by a detachable power plant of the type used for chain saws. The cylinder is a two way cylinder which moves faster in the retracting direction than in the force applying direction to speed up the cycle of log splitting and the cutting blade is provided with guide members which permit a split to be completed with a short power applying stroke.

摘要： A drilling attachment adapted to be fixed to a chain saw and a chain saw so equipped wherein the driving output shaft and a drill chuck are advantageously connected by a pair of friction drive wheels to produce clockwise rotation of the drill chuck and thus allow the use of standard and less expensive clockwise drills, to automatically provide for relative slipping without using a slip clutch, to produce the desired speed reduction, and to allow trouble and failure-free operation in the field, such as to drill holes in maple trees to collect the sap thereof. This drilling attachment includes a first friction drive wheel and a second friction drive wheel frictionally engaging each other with the second friction drive wheel rotatively carried by a bracket adjustably securable to the chain saw. A drill chuck is fixedly connected to the second friction drive wheel for bodily rotation clockwise therewith.
