  • Patent number: 4442636
    Abstract: An edge sharpening device that simultaneously sharpens the edge faces on both sides of the skis has a hand-grippable support (31) capable of changing in length that carries a pair of opposed edge sharpening heads (32, 33). The heads are movable to a spread position by the changing of the length of the support and a biasing band (61) urges the side sharpening faces (44, 45, 54, 55) of sharpening blocks against the side surfaces of the ski during a reciprocating movement of the device. The heads have bottom sharpening faces (48, 58) that are manually urged against the bottom surfaces of the ski during the reciprocating movement of the device. A flexible mounting provided by heads (68, 78) and sockets (64, 74) permits the heads to turn from side to side about a vertical axis to follow the taper of a ski of varying width during the sharpening operation.

  • Patent number: 4408363
    Abstract: The thread conditioning device is for rotational movement about a threaded bolt to remove corrosion and debris and to otherwise condition the bolt threads for further use. The device or chaser includes a body having an opened and generally C-shaped configuration when viewed cross sectionally to its axis of rotation. The body of the device includes an interior threaded surface to engage the threads of the bolt to be conditioned, an exterior surface to mechanically engage, grasp and rotate the device, and two generally opposing end surfaces. The open portion of the C-shaped body is defined by two lateral surfaces which extend between the opposing end surfaces from the interior surface to the exterior surface of the device. The two lateral surfaces preferably form positive, acute angles relative to the interior surface of the body when viewed cross sectionally. The intersections of the lateral surfaces and the interior threaded surface form two generally spacially opposing plowing edges of the device.

    Abstract: An ice scraper comprising a one-piece body defining a handle section, a downwardly curved intermediate section, and a blade region comprising a plurality of downwardly curved, independently flexible, resilient scraping fingers. In use, the scraping fingers bow or flex when scraping force is applied to ice to be removed, induce the formation of fractures in the ice, and thereafter resiliently return to their unflexed position, imparting force to fractured ice tending to throw it away from the surface to be scraped.The separable, independently flexible fingers enable the ice scraper to effectively conform to curved surfaces and avoid the possible incomplete cleaning action of said blade structures.

  • Patent number: 4156966
    Abstract: Disclosed is a blade for cutting and scrapping that is receivable by a holding device. A keeper is joined to a base plate of the holding device by means of a pair of screws. The blade is constructed with a pair of slots of different lengths extending inwardly from opposite ends of the blade and running generally parallel to the cutting edge of the blade. The blade may be inserted between the keeper and base plate with one screw being received by the longer of the two slots. The blade may then be positioned between the keeper and base plate with the shorter slot aligned with the other screw. The blade may then be moved forward so that the shorter slot receives the second screw while the longer slot still retains the first screw. Tightening the screws then secures the blade in cutting position between the keeper and the base plate.

  • Patent number: 4121337
    Abstract: The problem of defaced acoustical ceilings in homes, apartments, offices, etc., is eliminated in a highly simple and economical manner. The ceilings are defaced as the result of the removal of decorative hooks which suspend plants, etc. In accordance with the present method, the unsightly hole and surrounding defaced region are effectively obscured by first removing a circular region of acoustical substance from the underlying wallboard surface, the circular region having as its center the hole formed by the decorative hook. Thereafter, a circular patch of acoustical material is applied to the wallboard surface, completely filling the circular region from which the acoustical material was removed. The result is such that it is difficult to ascertain what part is patched and what part is not.In accordance with the apparatus, a circular patch of acoustical material (or simulated acoustical material) is provided in combination with a tool of corresponding size.

  • Patent number: 4106193
    Abstract: A rotary scraper including a spool with fingers integral therewith and projecting radially therefrom, with the fingers striking the work surface as the wheel rotates, thereby to impact the work surface; the fingers are arranged in a plurality of comb-like structures with the base of each comb inserted in a slot parallel to the axis of the spool. Each comb is locked in place by a cylindrical cover for the spool having a slot displaced radially from the slot in the spool into which each comb is inserted. Each comb is therefore held in place by the S shaped bend thus induced and is curved away from the direction of rotation from the spool. The fingers of each comb are relatively flexible. The curved portion of each comb outside the cover acts as a support for the fingers of the next adjacent comb should they be flexed inwardly beyond the desired point.
