Abstract: A manually operated, finger-manipulatable non-electric hair trimming device is provided for shaving nostril hair, ear hair or the like. The hair trimming device includes a head structure sized to fit within a small body cavity, such as a person's nostril or ear cavity, and is arranged to support a flexible razor blade strip. The head structure has a base portion and a curved guard portion extending from the base portion. The curved guard portion has first and second ends which are attached to the base portion. A finger grip portion is provided having an end connected to the base portion of the head structure, for manually manipulating the hair trimming device. The head structure further has a thin, elongated narrow razor blade strip provided with a razor sharp first edge portion.

Abstract: Several single-head bi-directional razor devices and systems are disclosed. Each has a narrow, elongated bi-directional razor head attached or attachable to a transversely extending hand grip. The razor head may be constructed as a disposable cartridge if desired. Two pairs of narrow, razor blade strips are positioned within the head, with one pair of blades extending in one direction and the other pair generally extending in an opposite direction. Both sets of blades extend along the length of the head. The user may move the razor head in one direction for contacting one pair of blades against the user's skin for cutting hair and then, without lifting or tilting or repositioning the hand grip, move the handle in the opposite direction so that the other pair of blades cuts hair during reverse movement of the razor. In other words, the head remains engaged upon the skin for cutting hair in both directions. In some embodiments, the razor head is rigidly attached to the handle.

Abstract: A small-size lightweight mustache shaving device, grippable between a user's forefinger and thumb, for enabling the user to precisely shave and edge his own mustache to a desired shape. The device is formed as an elongated flat narrow body having a forward head portion and an integral offset rear fingertip-grip portion. A small elongated flat razor blade strip is mounted upon the head portion and has its razor sharp edge extending laterally outwardly from the head portion. The razor-sharp blade edge of the device is placed by the user against his skin and/or mustache adjacent the periphery of the desired mustache line and then manually moved under fingertip control to shave and shape the hairs of the user's mustache. Several embodiments of the device are disclosed, including guarded, blunted and assembled blade designs, and all-metal designs.

Abstract: A bi-directional razor device is formed of a narrow, elongated head and a transversely extending, integral hand grip formed of molded plastic material. Two pair of narrow, strip-like razor blades are embedded in the head, with one pair extending in one direction and the other pair extending in an opposite direction at an acute angle relative to the first pair. The blades extend along the length of the head. Thus, the user may move the razor head in one direction for contacting one pair of blades against the user's skin for cutting hair and then move the handle in the opposite direction while the blades remain engaged upon the skin for cutting hair in both directions.

Abstract: A boring bar sleeve for mounting a boring bar upon a socketed tool holder of a machine tool is formed of an elongated tube having an outside diameter corresponding to the diameter of the tool holder socket for securing the sleeve within the socket. The tube has a forward end portion, which extends forwardly out of the socket, and within which different elongated tubular bushings may be inserted. The bushings all have the same outside diameter which corresponds to the sleeve inner diameter for interchanging one bushing with another within the sleeve. But, each bushing has a different inner diameter which is of a preselected size that corresponds to a preselected diameter boring bar. The bushings each have a longitudinally elongated slot formed through their walls. A series of longitudinally aligned, spaced apart set screws extend through threaded openings formed in the forward end portion of the tube and through the bushing slot to engage a boring bar inserted within the bushing.

Abstract: A manual tool useful for scraping, deburring and breaking the sharp edges of sheet material such as metal and glass and the like, formed of an elongated handle shaped to fit within the human hand and a pair of closely adjacent, conventional, wafer-like, hard cutter inserts mounted upon the forward end of the handle. A pair of sockets are formed on the forward end of the handle and each insert fits within a socket and is immovably held therein by means of a conventional fastener. The inserts each have a forwardly extending cutter edge, and the two cutter edges are arranged at an acute angle to form a V-shaped channel between the two inserts. The channel receives and is drawn along the sharp edge of the sheet material. The inserts are removable and replaceable, when desired, with similar inserts.

Abstract: A thin wall, U-shaped in cross-section, elongated cover is shaped to fit over the bristles and the bristle end of a toothbrush for covering and protecting the bristles. The free ends of the legs defining the U-shape of the cover, are provided with engaging formations for frictionally engaging the sides of the bristle carrying portion of the brush handle. The cover is formed of a springy plastic material so that the bristle carrying portion is resiliently clamped between the engaging formations of the legs. Thus, the cover may be manually applied upon and removed from the brush and will be tightly held upon the brush by the springy clamping action and the frictional engagement of the cover legs.

Abstract: A manual tool useful for cutting, scraping, deburring, marking and the like hand operations, is formed of an elongated handle shaped to fit within the human hand. The handle has a forward end formed with a socket for receiving a conventional, wafer-like, machine tool hard cutter insert. The insert fits within a socket which exposes a forward end of the insert and portions of the insert side edges for contact with a work piece. The insert may be fastened within the socket within the handle by means of a suitable, conventional screw fastener or the like. The insert may be pre-selected from a conventional insert having a conventional circular, square, diamond-shaped, hexagonal shape, triangular and the like peripheral edge and the socket is formed so that similar size, but different peripheral edge shaped inserts may be replaced, one for another, as desired. Thus, new or used conventional machine tool cutter inserts may be utilized in the tool at the user's option.

Abstract: A tubular bushing receives the shank of an elongated tool, such as a boring bar, drill and the like shank tools, for mounting the tool shank within the elongated tool socket bore of a tool holder or turret of a machine tool. A narrow slot formed in the tube wall extends substantially the full length of the bushing parallel to the tube axis. A considerably narrower slit formed in the tube wall extends from each of the opposite ends of the tube to the adjacent ends of the slots. A narrow, flat band extends along the interior of the tube wall, parallel to the tube axis and radially offset relative to the slot. Thus, set screws mounted in the tool socket defining wall and extending transversely of the socket engage either the flat band, to resiliently compress the bushing around the tool shank, or extend through the slot to directly engage the shank, for securing the tool and bushing within the socket.
