Notches of different sizes are provided centrally of the upper and lower edges and the head is reinforced by a rearwardly extending neck which, in a preferred embodiment, includes a pair of spaced notches oriented rearwardly of a rear face of the head and toward a handle of the tool.

Abstract: One object of the present invention is to provide a blade for forming ribs that is able to improve wear resistance; in order to achieve the object, the present invention provide a blade for forming ribs that forms ribs either on the surface of a substrate or via an undercoating layer on the surface of a substrate by moving a blade body in a fixed direction relative to a paste film in the state in which comb teeth formed on at least a portion of the periphery of said blade body are penetrated into said paste film formed on the surface of said substrate to plasticly deform said paste film; wherein, the surface of said comb teeth formed on said blade body that makes contact with said paste film is coated with a compound layer in which hard particles are dispersed in a metal.

Abstract: Conductive devices and tools to provide electrical conduction with a generally planar conductor which is covered with an insulation substance such as paint, rust or dust, by scraping a portion of the conductor and removing the insulation substance. A conductive device includes a conductive metal serration means and a tool utilizes such a serration device. Such a serration device can be a bolt device, nut device or washer device, or washer-incorporated threaded device. A connector device is also disclosed to provide electrical conduction between a conductor and a conductor plate covered with an insulation substance.

Abstract: A scraper for use with solvents and cleaners, particularly gel-type solvents which do not soak into carpet, to remove gum, grease, paint, and wax from carpeting. The scraper is preferably a single piece of plastic having an elongate handle portion which is held in hand generally parallel to the carpet and which handle curves downwardly ending in a working portion having a textured surface disposed generally parallel to the carpet. The textured surface preferably includes a plurality of transverse, forward-tipped teeth such that after application of the solvent to the gum, grease, paint, or wax, the scraper is moved in a forward, vertical, semi-circular motion such that the teeth engage the gum, grease, paint, or wax in a single direction parallel to the carpet and then lifted therefrom and moved backwards for a repeat stroke. The teeth act to agitate and work the gel into the gum, grease, paint, or wax, producing small waves of loosened material.

Abstract: A spreader for use in spreading a bed of predetermined thickness of adhesive material on a prepared floor surface prior to the laying of tiles. The spreader comprises a rectangular planar portion (2) having a serrated lower longitudinal edge (4) and flanges (6 and 8) extending substantially at right angles from the transverse edges of the rectangular planar portion (2). The flanges provide a barrier allowing a mass of adhesive to lie in front of the serrated edge (4) and between the flanges (6 and 8) as the spreader is drawn over the surface of the surface to be tiled. As the spreader is drawn over the surface the adhesive flows under the serrated edge thereby providing an even application of adhesive across the full width of the spreader. A height adjuster comprising an adjustable gauge (28) is provided as is a handle (10) or elongate handle (50) for convenient use by the tiler.

Abstract: A wallpaper scarifying device including a plate and at least one scarifying assembly coupled to the plate. The scarifying assembly includes a swivel fixture rotatably coupled to the plate about an axis of rotation and rotatably carrying a cutting disk at an angle of less than 45 degrees relative a plane perpendicular to the axis of rotation. The cutting disk has a plurality of teeth extending from a periphery thereof.

Abstract: The tool of the present invention is designed to facilitate small repairs in walls. It is useable to repair dents, holes, and cracks in dry wall, plaster, stucco, or like materials. It is also useable to install drywall. The tool has a plurality of groove forming cutting edges which are used to cut into the damaged area or the non-beveled peripheries of newly installed panels to a predetermined depth. The grooves help loosen the material. A gouging blade of the tool is used to remove the weakened material and form a trough of a predetermined depth. Edges of the head of the tool project out on either side of the gouging blade to act as a depth control agent. The tool of the present invention is used in the method of the present invention in which a plurality of grooves are formed centered on a crack, criss cross grooves are also formed to further weaken the layer of the wall material, a trough is gouged out, netting is placed in the trough, and compound or plaster is spread into the trough.

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.

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.

Abstract: A tool (1) for spreading adhesive over a substrate has a blade edge (4) with a set of spaced large indentations (5) and at least one set of spaced smaller indentations (6) extending into the blade edge. The smaller indentations extend into the blade less than any one of the large indentations and are interspaced between the large indentations. The blade edge is slid over the substrate to which adhesive has been applied and the adhesive is spread such that the large indentations form large ridges (20) of adhesive projecting from the substrate. The smaller indentations form smaller ridges (21) of adhesive projecting from the substrate and the smaller ridges (21) are interspaced between the large ridges (20). When a tile (23) is pressed into the adhesive the larger ridges (20) are compressed first, thereby broadening the ridge and pushing adjacent ridges into the smaller ridges (21). In this any void between ridges is more readily filled and a more uniform spread of keyed in adhesive is achieved.

Abstract: A novel plaster application method includes the first step of applying the plaster in a plurality of parallel and spaced apart lines using a novel hand tool so that the upper edges of each plaster line define the plane of the final plaster surface. After allowing the plaster lines to dry and harden, the second step is to fill the spaces between the lines with more plaster forming the final plaster surface by raising the level of plaster to the plane of the final surface. More layers of plaster may be applied if needed. A serrated hand tool is proposed for aiding the plaster spreading which contains a plurality of generally triangular teeth with oval upper portions and blunt lower ends defining the distal edge of the tool. The new method allows a faster application of plaster in a construction practice with reduced consumption of plaster material.
