Abstract: A drive sprocket for use with an elongate, endless saw chain, the sprocket being a substantially circular member having pockets spaced circumferentially thereabout for receiving drive tangs on the saw chain and edge margins adjacent the tang-receiving pockets against which surfaces of side links of the saw chain may rest. The pockets have enlarged portions, or bores, opening radially outwardly from the sprocket, which bores are wider than the side-to-side dimension of the side links on the chain to allow debris to clear radially from the pockets past the sides of the chain during operation. The sprocket also may have axial ports intersecting the radially disposed bores.

Abstract: An infusion package, such as a tea bag, having porous side panels and an open mouth through which material may be inserted. Edges of the package at the mouth are foldable over each other to close the mouth. A string on the folded over portions is extended through an aperture remote from the mouth and serves to inhibit unfolding.

Abstract: A fluid container and dispenser including an elastomeric reservoir and a dispensing tube connected thereto and a valve to either allow or inhibit fluid flow into or out of the reservoir. One embodiment includes an elongate tube with a hole in one side and an elastomeric sleeve surrounding a portion of the tube. A sliding valve element is mounted in the tube to close the hole. The valve element is mounted on a second, smaller tube which slides within the first-mentioned tube. The sleeve is filled by sliding the valve element away from the hole and injecting fluid under pressure into the sleeve to expand it. The valve then is slid to its closed position. The combined first-mentioned and second tubes together form a straw to withdraw fluid from a secondary container into which fluid may be dispensed.

Abstract: A cutting chain for a chain saw including a safety element normally preventing the cutter tooth from cutting wherein the safety element is mounted on the driver link and by inward pressure; i.e., toward the cutter bar, is rotated to a position under the cutter tooth so that the latter may cut.

Abstract: A cutting chain for a chain saw including a safety element in front of a cutter tooth, the safety element normally extending past the cutter tooth to inhibit cutting, but depressible by a solid object such as wood to allow cutting.

Abstract: A cutting chain for a chain saw including a clearer immediately in front of the cutter tooth, the clearer normally extending past the cutter tooth and preventing cutting but depressible by a solid object such as wood to allow cutting.

Abstract: A telescopic sight mount having a base portion, cap means flexibly connected together at a joint above the center line of the sight mount and connectable to the base portion and tightening means for connecting the cap means to the base portion at a point below the center line of the sight mount is provided.

Abstract: A guide bar has a main body section and a separate nose section releasably secured thereto. The main body section has a pair of opposed recesses in opposite faces thereof and an opening in said recesses to form a flange. The nose section includes a pair of opposed plates, at least one of the plates having a central portion deformed laterally toward the other plate. The plates are secured together in the region of lateral deformation with edge margins thereof spaced apart to provide a drive chain-receiving groove generally aligned with a similar groove in the peripheral edge of the main body section. The body and nose sections are secured together by a hub and expander member assembly which extends into substantially aligned apertures in the body section and nose section. Edge margins of the recesses on the body section and nose section are disposed at diverging angles progressing toward the nose end of the bar to aid in alignment and securing of the body and nose section.

Abstract: A drive sprocket for use with an elongate, endless saw chain, the sprocket being a substantially cylindrical member having pockets spaced circumferentially thereabout for receiving drive tangs on the saw chain with sprocket edge margins adjacent the tang-receiving pockets providing support for bottom surfaces of the side links of the saw chain. The pockets have enlarged clearing portions opening radially outwardly from the sprocket which are wider than remainder portions of the pockets. The clearing openings are configured and positioned to allow debris to clear radially from the pockets.

Abstract: A circular saw blade having a plurality of circumferentially-spaced cutter teeth projecting radially outwardly therefrom. A portion of the periphery of the blade rises gradually as it progresses toward the front face of a tooth to provide a depth gauge to control depth of cut. A chip clearing channel extends radially inwardly along the body of the blade adjacent the front face of the tooth. A pocket formed in the body has edge margins which receive and support front and rear surfaces of a cutter tip.

Abstract: An elongate unitary splitting device having a lower portion of multiangular configuration with a pair of opposed edges converging at a first angle toward a pointed lower end. An upper portion additionally has a pair of oppositely facing, generally planar side surfaces which intersect and extend upwardly from said edges. The angle between the side surfaces is at least as great as the angle of convergence of the opposed edges. A spear-point configuration provided by the lower end produces ease of startup penetration, and the upper portion produces efficient splitting once initial penetration has occurred.

Abstract: A method for making a plated soft nose bullet and the product resulting therefrom, wherein a core is formed of a deformable first metal and the entire core is then covered with a second metal by an electroplating process. The electroplated second metal is removed from the forward end of the core to expose a portion of the first metal. The plated core then is formed into its final shape in such a manner that a quantity of unplated core material is extruded from the remaining plated portions to form an unplated soft nose for the bullet.
