  • Publication number: 20150068044
    Abstract: An edge beveling tool for working leather including a handle; a cutting member comprising an arm with first and second ends, cutting surface(s) being provided on the second end, and a spring assembly for removably engaging the cutting member with the handle. The first end of the cutting member is inserted into a slot defined in the handle and is engaged by the spring assembly. The spring assembly is a spring clip which urges the first end of the cutting member into contact with an interior wall of the handle. When it is desired to replace the first cutting member with a second cutting member having a different cutting profile, the first cutting member is grasped and pulled out of the slot. A first end of the second cutting member is then inserted into the slot where the spring clip urges it contact with the interior wall of the handle.

    Abstract: A scraper tool of a one piece construction is conformable for use in scraping various surfaces and is made up of a pair of scraper blades (13,13?) with their junction along the length of the tool, under its handle (12). The blades extend in opposite directions under the handle (12), in line with it, at a set angle forming an open bottom, with the handle (12) above the blades (13,13?) and the surface to be scraped. The application of force and direction of travel will allow the forward blade to “cut” substrates from a surface, the rear blade will maintain a cutting angle for the forward blade, the device will operate in a similar fashion on its reverse stroke.

    Abstract: An adhesive substance removing tool is provided with a cracking tool and a scrapping assembly which are removably coupled to a base. The cracking tool is used to crack the adhesive substance by forming breaking lines on the surface of the adhesive substance, and then the scrapping assembly is used to scrape off the adhesive substance by starting from the breaking lines. The combination of the cracking tool and the scraping assembly allows the user to remove adhesive substance easily and completely. Besides, the cutting assembly of the cracking tool is able to move freely both in straight-line or circular fashion, and the cracking tool can be prevented from rotating or disengaging once it is positioned in place on the base. Hence, convenience and safety of use can both be assured.

    Abstract: In a preferred embodiment, the push-pull stripper-scraper comprises a single stripping blade and a quadruple-edged scraping blade. The stripping blade accommodates a sliding carrier plate which incorporates guide channels for sliding along the stripping blade. The carrier plate is adapted to retain the scraping blade, thus, the scraping blade moves in unison with the carrier plate as it shifts in position along the stripping blade. The carrier plate, stripping blade and scraping blade also include apertures through which a fastening means secures these respective components but which nevertheless selectively permits movement of the carrier plate along the stripping blade. Significantly, the device allows a user to switch between using the stripping blade and scraping blade, respectively, without changing tools. This is particularly advantageous when using the device in conjunction with an extension pole.

  • Patent number: 7103936
    Abstract: A wood scraper having two oppositely angled blades on a single head, and preferably two heads with two oppositely angled blades on each head. Thus, on both the forward and reverse stroke, there are two spaced apart blades scraping the work piece. This covers twice the surface area with the same effort as a single-bladed or single-headed scraper. All the blades are rigid and have a straight edge. All the blade edges are aligned with the planar surface of the work piece. This produces a level cut and makes the tool more stable, making gouging unlikely and enhancing the efficiency of the scraping action. The tool can be operated easily with one hand. In addition, the use of straight blades allows all the blades to be sharpened easily and quickly and at the same time using a belt sander or on a sheet of emery paper on a flat surface.

In use, the tip of the scraper head is positioned at the junction between a textured ceiling and a wall, and the scraper head is moved with the extension pole along the junction such that the blade end portions cut away excess texture material. A straight line is created at the junction in preparation for painting of the wall.

  • Patent number: 6243906
    Abstract: A combination ice scraper and snow removal assembly which has multiple blades in contact with the working/windshield surface to more efficiently remove ice and snow therefrom and reduce the amount of energy expended by the user to scrape and remove snow from the working surface. This combination ice scraper and snow removal assembly includes a main body portion having two ends thereof. A scraping assembly is provided at one end of the main body for scraping a frozen water material from a working surface. The scraping assembly includes at least three scraping blades with at least one of the scraping blades having a continuous blade edge and at least two of the scraping blades having toothed cutting edges. As a result, in a single swiping or scraping action of the user, ice or snow can be dislodged from the working windshield/surface by the scraping blade assembly and then cleared and/or removed from that dislodged location by the cleaning blade removal assembly in a limited path of travel.

  • Patent number: 6237181
    Abstract: The present invention “A Comb for Removing Debris on Carpet” is a hand held tool that will comb debris such as pine needles or other debris left lying on carpet or embedded in carpet into a pile for easy pick-up. This tool consists of a body, a handle, and a plurality of plates that are spaced, varying in height, and extended the entire length of the body. These plates extend upward into parallel grooves cut into the underside of the body and are permanently attached there. These plates also extend downward from the body and have a plurality of teen that are distal from the body deposed on the edge of each plate. The teeth are in a saw-toothed configuration. The tool is held in the hand(s) and is drawn towards the operator. The plates and teeth are in contact with the carpet. The manual action of drawings the tool over the carpet results in the collection of debris at the front side of the tool and between the plates.

  • Patent number: 6098292
    Abstract: A tool having a flat, quadrangular shaped blade with a straight front edge and a parallel back edge, the front edge being tapered to provide a cutting edge. A handle receiving tube extends upwardly and rearwardly from the top of the blade, the tube being centered between the sides of the blade. At least one impact receiving member is on the tool positioned to allow the blade to be hammered in a direction to drive the blade forwardly to have the front edge of the blade cut through material. A groove is formed in the bottom surface of the blade, the groove being unshaped with the base of the groove parallel to the front edge of the blade and located in front of the handle receiving tube. The groove forms a strengthening ridge on the upper surface of the blade. A strengthening strap is fastened to the lower, front portion of the handle receiving tube and extends forwardly on the upper surface of the blade toward the front edge of the blade.

  • Patent number: 6023811
    Abstract: A modular, grout removal tool of adjustable thickness, to better accommodate grout joints of varying widths on all types of tiled surfaces. The tool has a handle with a pear-shaped cross section and a protrusion extending from and continuous with its substantially rectangular base. The protrusion has a substantially rectangular cross section and a lower relative height than the rest of the handle, which affords the tool access to hard-to-reach grout joints, such as those situated under overhangs created by cabinet and appliance edges. The protrusion also functions as a thumb rest during use. Rectangular flanges at the bottom of the base curve inward to define a slot extending into the base for a plurality off carbide-tipped saw blades. The blades have apertures aligning with apertures in the flanges to receive securing screws upon insertions of the blades into the slot.
