  • Patent number: 5553718
    Abstract: A wall mount is provided which supports an automotive bicycle rack of the type having a plurality of feet which engage the rear portion of an automobile and straps with hooks for releasably securing the rack to the automobile. The wall mount is a ladder-like device which comprises a pair of vertically disposed rails for fastening to a wall and a plurality of horizontal cross-beam members disposed in vertically spaced orientation on the rails. An uppermost cross-beam member has an upwardly opening "J" cross section and the lowermost cross-beam member having a downwardly opening "J" cross-section, for receiving the hooks of the rack. A pair of intermediate cross-beam members are spaced between the uppermost and lowermost cross-beam members and have vertical surfaces for receiving the feet of the rack. The vertical surface of the lower of said intermediate cross-beam members is disposed approximately 3 to 4 inches further from the wall than said other vertical surface to mimic the bumper of an automobile.

  • Patent number: 5551456
    Abstract: An applicator brush for fluid-type cosmetics, such as may be used in applying mascara to eyelashes which includes a bristle portion disposed at one end of a helical twisted wire core with a handle disposed at the outer end. The configuration of the bristle portion is such that the bristle tips define a generally cylindrical outer surface having two (2) diametrically opposed channels and application surfaces helically disposed along the length of the brush portion which are spiraled about the core to form a helix thereof. The brush portion is formed by disposing the bristles between the lengths of the wire and helically twisting the wire to form the core that retains the bristles therebetween. The bristle portion is then trimmed to a shape of generally rectangular cross-section. To form the helical application surface, the wire core is further twisted in the same direction a predetermined number of turns.

  • Patent number: 5437118
    Abstract: A frame plug or closure member which is fitted into a cavity of a handgrip of a handgun is used to provide added reenforcement and to extend the handgrip. The plug has a tapered, semi-circular shaped base which is integrally connected to one end of a flexible flat, elongated member which has a foot at the other end thereof. The curvature of the base matches the curvature of the lower edge of the handgrip to provide a natural extension to the handgrip. The plug has a spine integrally connected to both the base and flexible elongated member so as to provide stiffness thereto. The handgrip has a plug cavity and an adjacent gun magazine cavity which open to the lower edge or butt thereof. The two cavities are separated by an internal wall having a through opening. The frame plug is fitted into the plug cavity until the foot reaches the opening at which time the foot snap fits into the opening thus securing the frame plug to the handgrip.

  • Patent number: 5435411
    Abstract: A dual purpose roll work stand, adapted to support elongated material and permit the user to easily move the material across the stand surface, includes a base member mounted to a vertical support which can be adjusted to raise or lower the height thereof, a row of discrete ball bearing units mounted to the upper surface of the base member to permit the material rested thereon to be move in any direction and a roller disposed between two brackets that are rotatably secured to the ends of the base by two knurled knobs. The roller may be positioned directly above the upper surface of the base to support the material thereon and moved unidirectionally perpendicular to the axis of the roller. The brackets may be rotated from the upright position along side the base to allow the material to be supported on the ball bearing units and moved omnidirectionally.

  • Patent number: 5410935
    Abstract: An improved saw blade includes groups of saw teeth disposed along the cutting edge of the blade. Each group of teeth includes, in relation to the cutting direction of the blade, an unset leading tooth followed by two pairs of trailing teeth alternately set in opposite lateral directions outwardly of the centerline of the blade. The first pair of trailing teeth are generally of the same height as the leading tooth and the second pair of trailing teeth are shorter and have a substantially wider set than the first pair. The pair of trailing teeth that are shorter and wider set are disposed in consecutively and interposed relation between the first pair of trailing teeth. The set distance of the first pair of trailing teeth is approximately 50% of the set distance of the second pair of trailing teeth.
