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.

Abstract: A magazine safety for a semi-automatic pistol with a double-action firing pin striker mechanism having a lever pivotable to the frame of said pistol so that the forward end thereof will sense the presence of the magazine in the pistol. The lever is provided with a downwardly opening recess on its underside and a spring disposed to urge the lever to engage a pin extending laterally from the sear of the firing mechanism of said pistol. The pistol further includes a trigger bar movable in response to the trigger and is engageable with the sear for cocking and releasing the firing pin to fire the pistol. When engaged with a sear pin, the recess in the lever serves to prevent movement of the sear for firing the pistol whenever the magazine has been removed from the pistol. The lever having its center of gravity disposed to ensure that the lever will engage the sear to prevent firing of the pistol even in the event the safety spring is rendered inoperable.
Abstract: A magazine for a semiautomatic handgun is provided which includes a butt plate being slidably secured to the bottom thereof by side walls having slots which engage flanges on the lower edge of the magazine tube. A floor plate which serves as a seat for the magazine spring has a tang disposed on its leading edge which interfits with a slot disposed on the forward edge of the magazine tube and which serves to secure the leading edge therein. The floor plate also includes a lug which is biased by the magazine spring to interfit with a hole in the butt plate to prevent the butt plate from being slidably removed from the magazine tube.
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.
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.
Abstract: A bimetallic band saw blade has a high speed cutting edge welded to a backing band of a steel alloy containing the following elements percentages by weight:Cr - 0.5% to no more than 1.5%V - 0.10% to 0.75%Mo - 1.5% to 2.5%wherein said backing band comprises a substantially lesser amount by weight of Chromium than Molybdenum the alloy also contains C, Si, Mn, Nb and/or Ni and Al in such varying amounts that the total alloy content, except for Fe and inevitable impurities, is in the range of 3.12% to 8.48%.
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.
Abstract: An ergonomic semi-automatic handgun includes a pivotable trigger with a concave face portion disposed in front of the grip portion whereby when the trigger is pivoted, the center of the concave portion will travel in a generally straight line towards the base of the saddle parallel to the axis of the barrel and at an optimum distance from the barrel. A unitary polymeric frame including a semi-cylindrical front strap is disposed at predetermined angle relative to the barrel. A ridge and channel are formed on each side of the frame and are adapted to guide and retain the thumb and forefinger of a shooter in the appropriate position to hold, aim and fire the gun.

The anchor portion has a plurality of legs spaced apart in a peripheral array and which extend downward from the upper portion. Each lo leg has at its lower end a radially extending foot having a beveled lower surface adapted to engage the outer edge of the opening and to flex the legs inwardly for fitting into and through the opening.
Abstract: A two-piece safety trigger for a handgun or pistol fabricated from high impact polymer is provided in which a lower portion comprising approximately the entire lower half of the trigger face is pivotable relative to the upper portion. The lower trigger portion includes a rearwardly extending latch portion which, when the lower trigger portion is in its forward position, serves to engage the frame of the gun to prevent firing movement of the trigger in the event the gun is dropped or otherwise impacted. The lower trigger portion is biased to its forward position by a flexible spring finger disposed within the upper portion and is adapted to be overcome when the user squeezes the trigger in a conventional manner.
