Patent number: 6421923Abstract: A carpet trimmer comprises a base plate with first slots. Underlying the base plate is a post holder with upstanding threaded posts protruding through the first slots of the base plate. Overlying the base plate is a blade holder that engages the posts for movement with the post holder. A wall guide is formed from the blade holder by bending downwardly in spaced relation to the working edge of the base plate. A first indent is formed on the bottom surface of the blade holder at the junction between the wall guide and the blade holder. The blade holder has a first blade holding recess with a second slot exposed when a blade is in place. A notch on a blade-supporting strip attached on the inner wall of the wall guide, the inner wall, and the first indent forms a second blade holding recess. The first and second recesses define a blade holding area that has a length longer than the blade's length.Type: GrantFiled: July 31, 2001Date of Patent: July 23, 2002Assignee: Crain Cutter CompanyInventor: Tan Dinh Nguyen

Patent number: 4095341Abstract: A carpet trimmer comprising a base plate with slots directed at right angles to the working edge of the base plate. Underlying the base plate is a post holder with upstanding threaded posts protruding through the slots of the base plate. Overlying the base plate is a blade holder that engages the posts for movement with the post holder. Suitable nuts on the posts lock the post holder and the blade holder in an adjusted position relative to the base plate. A wall guide depends from the blade holder in spaced relation to the working edge of the base plate to define a passageway for a carpet edge to be trimmed by blades on the blade holder. When the nuts are loosened, the posts can be moved within the slots of the base plate toward or away from the working edge of the base plate. In so doing, the post holder and the blade holder move therewith. This action adjusts the distance between the working edge of the base plate and the wall guide to accommodate different thicknesses of carpets.Type: GrantFiled: October 25, 1977Date of Patent: June 20, 1978Assignee: Crain Cutter Company, Inc.Inventor: Millard Crain
