  • Patent number: 5343623
    Abstract: A knife blade and knife blade assembly are disclosed for cutting food products into sticks or slices without causing surface cracking. The knife blade has a cutting portion defining a cutting edge and is mounted in the knife assembly such that a tension force is exerted on the knife blade in the plane of the cutting edge. The cutting edge of the knife blade is not sharp, but is generally flat and extends between parallel sides of the knife blade. The individual knife blades are formed of stainless steel and are electro-polished to remove any surface defects or sharp edges which may produce stress concentrations. This enables a significant tension force to be applied to the knife blade without diminishing its useful life. The electro-polishing process may also round off the corners of the juncture between the flat cutting edge and the parallel knife blade sides.

  • Patent number: 5343622
    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.

  • Patent number: 5341996
    Abstract: An apparatus is described for separating components of rubber vehicle tires. This apparatus has two, substantially parallel platforms, one above the other, and a means for varying the separation between them. A rubber tire to be processed is positioned on the lower platform on a rotatable portion thereof. The upper platform has mounted thereon a plurality of rotary nozzles through which high-pressure fluid is directed onto said tire, fragmenting the rubber components from said tire and flushing them away with the effluent stream of fluid while leaving substantially clean steel cord behind on said lower platform.

  • Patent number: 5339526
    Abstract: A resistance spool (16) for holding lines (38,40) in a line trimmer head (10) is disclosed. The spool (16) has a rotatable main body (19) having lines (38,40) wound thereon. The wound lines (38,40) have free ends (42,44) which extend radially from the main body (19). Clamp portions (32,34,36), on the main body (19), restrain the free ends (42,44) of the lines (38,40). The clamp portions (32,34,36) restrain the free ends (42,44) so that the lines (38,40) do not unwind from the spool (16) when the main body (19) is not rotating at a sufficient speed and allows the free ends (42,44) of lines (38,40) to pay out from the spool (16) when the main body (19) is rotating at a sufficient speed. Preferably, the main body (19) includes a hub (20) and axially disposed flanges (22,24,26) extending radially outwardly from the hub (20). The flanges ( 22,24,26) cooperate with one another to pinch the line (38,40) such that the line (38,40) may not unravel during installation of the spool (16) within a line trimmer head (10).

    Abstract: A new and improved automatic shaving apparatus includes a handle assembly which includes a pressurized foam dispensing assembly and an electric valve control assembly. A shaving head assembly is connected to the handle assembly and retains a razor blade assembly. The handle assembly serves as a handle during shaving and also serves as a housing for the pressurized foam dispensing assembly and the electric valve control assembly. The pressurized foam dispensing assembly stores and dispenses shaving foam from the shaving head assembly. The electric valve control assembly controls release of shaving foam from the pressurized foam dispensing assembly. An electric power source powers the electric valve control assembly. A switch assembly is placed in circuit between the electric power source and the electric valve control assembly for controlling electric power to the electric valve control assembly.

  • Patent number: 5335418
    Abstract: A hand tool includes first and second lever members which intersect and have aligned openings therethrough in which is received a flexural pivot assembly, including a pair of cylindrical members respectively disposed in the lever member openings and respectively fixed to the lever members for movement therewith. In one embodiment the cylindrical members of the pivot assembly are press fitted directly in the openings of the lever members. In another embodiment, bushings are press-fitted in the openings between the lever members and the cylindrical members. A spacer is disposed between the cylindrical members to prevent their axial movement toward each other, and the spacer may extend between the lever members and has a very low coefficient friction so as not to impede pivotal movement of the levers.

  • Patent number: 5333381
    Abstract: A cutter for removing overwraps or tape on products and product packages incorporates first and second wings extending angularly from a body. A cutting point extends a short distance into the angle between the wings, wherein the wings embrace an edge of a product and the blade slices the wrapper along the edge as the user slides the cutter along the edge. The wings are flexible to conform to the angle of the edge, and are integrally molded with the body. Living hinges provided between the wings and the body, or the wings are molded angularly with respect to the body. A cutter is molded as a flat blank and folded. A solid article is molded with a pocket for insertion of the blade. The angle between the wings is less than or equal to 90.degree., allowing it to conform to most standard packages. The reduced angle between the wings and the relatively slight exposure of the blade allows for effective cutting of the wrapper without scarring the package or injuring the user.

  • Patent number: 5331742
    Abstract: The invention relates to end cutters, in particular for cutting through cables, having two flat loose blades which are located one on top of the other, and rotatable about a common rotation shaft and can be driven by means of a drive device. Each loose blade is in this case acted on by a suitable cam disc which is located in the plane of the blade and is coupled to the drive device. A desired force response while cutting up material in the form of ropes can be achieved in a simple manner by selection of the radii of the cam discs.

  • Patent number: 5325594
    Abstract: A hand-operated tool for cutting fibrous compressible insulation batts, and similar fibrous compressible materials. The tool, includes an elongated cutter blade housing, and a planar sheet of plexiglass, bent into a "C"-shaped configuration. End portions of the "C"-shaped plexiglass sheet fit over the ends of the cutter blade housing, so that the "C"-shaped sheet forms a presser element for the insulation batt, when placed on the top surface thereof. When the cutter blade is drawn through the batt material, the presser element compresses the material into a relatively small thickness, so that the cutter blade is enabled to completely penetrate the batt material. An insulation batt, therefore, can be neatly and completely severed, with one pass of the cutting tool.

  • Patent number: 5323538
    Abstract: A device for punching holes in artificial fingernails comprising a piston-cylinder unit having a cylinder wall with an aperture in it extending across the whole of the cylinder. The aperture is banana-shaped in cross-section and wider than the internal diameter of the cylinder with the convex side of the aperture facing the piston. The pointed end of the piston has a sharp knife-edge. The hole punch is operated by holding it between the thumb and index and middle fingers and pressing, causing the pointed end of the piston to travel past the curved cylinder-wall aperture in which the artificial fingernail to be perforated has been placed.
