    Abstract: The cushion back carpet cutting tool is a hand tool for cutting foam back carpeting that creates a clean straight cut through the carpeting so that a smooth unnoticeable seam results where two pieces of carpet material are brought together. The tool includes a leading edge on the center plate that opens the adjacent rows of tufts in the carpeting, three blades for cutting the carpeting between adjacent rows either close to the right row of tufts, left row of tufts or midway between the tufts, three plates that retain the blades and an adjustable retainer system for the blades, and a handle. The leading edge has an angle of less than 90 degrees from the horizontal and is rounded in shape to prevent loop or woven carpeting from catching on the tool, and also to keep the tool from jumping out of the row where the cut is being made. The blades are kept in place at an angle of between 15 to 25 degrees from the bottom edge of the tool, which results in a smoother cut being made in the carpeting.

  • Patent number: 5622093
    Abstract: A windshield removal apparatus that includes a suction cup assembly that is secured, via a vacuum, onto the interior center portion of an automobile's windshield. A swivel head is located at the opposite end of the assembly where the vacuum interface is initiated. The swivel head rotates bi-directionally 360 degrees in approximately the same plane as that of the windshield. The rotation of the swivel head is relatively friction free. A spring is located between the swivel head and the cutting wire which is in turn attached to a grip, to complete the configuration of the apparatus. The cutting wire is initially threaded through the seal between the windshield and automobile. The connection of the cutting wire to the spring and swivel head may take place in any order such that the apparatus is in the appropriate position to commence the cutting process of the entire perimeter of the seal.

  • Patent number: 5581889
    Abstract: A versatile hand-held garden tool for cultivating, digging, weeding, pruning and trimming has a blade, a handle and a neck angling upwards from the blade that connects the blade to the handle. The blade has a body portion that is preferably 5"-7" long and a tip portion angling upwards from the body portion that is preferably about 1 inch long. The body portion has two edges, one edge is serrated and the other edge is beveled. The tip portion has a beveled edge. It is preferred that the handle have a V-shaped cross section to facilitate the mounting of a grip. The garden tool can be made by cutting a blank from a web of cold rolled steel having a thickness of about 0.075 inches, coining the beveled edges into the blank, and forming the tool by bending the blank. It is then preferred to heat treat and plate the cold rolled steel.

  • Patent number: 5581895
    Abstract: An ergonomically-designed, multipurpose knife having a handle, a blade with a shank and a tip, and a fastener for attaching the handle to the shank. The blade has a curved outer edge extending substantially from the shank to the tip, with an integrally-formed gut hook positioned near the shank and opening toward the tip. A portion of the outer edge is sharpened to form a cutting edge. The fastener is user-operable for moving the blade from a first operating position where it opposes the handle to a second operating position where it extends forward of the handle for use as a hatchet. In the first position, force exerted on the handle and directed toward the blade is distributed approximately uniformly along the entire length of the outer cutting edge.
