Patent number: 6170222Abstract: An apparatus which is useful on pitched roofs includes structural features which help keep roofing materials from sliding off the roof. The apparatus also protects roofers from heat and abrasion from the roof surface on which they are working. A substantially solid foam rubber wedge forms one component of the apparatus, and a substantially planar pad forms the other component of the apparatus. These components are placed in proximity to each other so that the roofer, when situated on the pad, can readily reach roofing materials disposed against the wedge. The wedge resiliently compresses when roofing materials are placed on its upper surface. This resilient compression, the angle of orientation of the wedge's upper surface, and the frictional engagement of the wedge with the roof surface each contribute in varying degrees to holding roofing materials in position on the roof.Type: GrantFiled: August 2, 1999Date of Patent: January 9, 2001Assignee: Malco Products, Inc.Inventor: James Miller

Patent number: 6125720Abstract: A roofing material and roofing fastener removal tool. The tool comprises a handle attached to a blade. In the preferred embodiment, the handle is adjustable relative to the blade. In this embodiment, a portion of an adjustment assembly provides additional pivot points to extend the working range of the blade. The blade includes two rows of material engagement portions. The rows include large teeth and small teeth spaced evenly and regularly along the working edge of the blade. The larger teeth are thinned and rounded to facilitate insertion between roofing material and a structure, while the smaller teeth are thinned on one side only and rounded to facilitate insertion and engagement with roofing material and roofing fasteners. The teeth are separated from each other by tapered slots which are sized to engage shanks of roofing fasteners.Type: GrantFiled: October 22, 1998Date of Patent: October 3, 2000Assignee: Malco Products, Inc.Inventor: Bret A.

Patent number: 6113169Abstract: A magnetic device for picking up ferrous metal debris, such as nails, screws, sheet metal fragments, staples, rivets, and other ferrous metal objects from an environmental surface such as the ground or a floor by rolling along the surface, consists of: a magnetic pickup member; a pair of wheels mounted to the magnetic pickup member and supporting the magnetic pickup member slightly above the environmental surface; a handle; a wiper for scraping ferrous metal debris from the magnetic pickup member and biased against the magnetic pickup member; and a release rope for rotating the magnetic pickup member against the wiper, thereby dislocating ferrous metal debris from the magnetic pickup member. Optionally, a hopper may be attached to the device for receiving the ferrous metal debris.Type: GrantFiled: October 27, 1999Date of Patent: September 5, 2000Assignee: Malco Products, Inc.Inventors: Bret A. Gohman, Kyle A. Bjork

Patent number: 5077899Abstract: A blade for cutting a groove in ductboard and forming a corresponding scrap strip of ductboard. The blade includes two blade portions depending from a support member such as a hand tool with a sled for engaging the ductboard. Each of the blade portions includes an inner end which engages the other inner end to partially fix the blades relative to each other and partially restrict the blades from spreading which may be caused by the horizontal grain of ductboard.Type: GrantFiled: December 6, 1990Date of Patent: January 7, 1992Assignee: Malco Products, Inc.Inventors: James K. Rancour, John F. Wozniak

Patent number: 5048575Abstract: A tensioning and cut off tool for applying a strap to a bundle or to circular flexible air duct which is being joined to circular metal duct work. The tool includes a quick release operating mechanism to suddenly cut the strap when a predetermined force is applied to the handles of the tool, and further includes an adjustment means for adjusting the predetermined force for cutting the strap. An improved strap engaging mens is also disclosed that includes a discontinuous edge that engages the strap during the gripping and tensioning of the strap of minimizing the chances of a severing of the strap by the strap engaging means.Type: GrantFiled: August 13, 1990Date of Patent: September 17, 1991Assignee: Malco Products, Inc.Inventor: Lester N.

Patent number: 4947901Abstract: The present invention is a tensioning and cut off tool for applying a strap having a locking collar and a free end to a bundle. It features a quick release operating mechanism that cuts the strap with a snap action in response to a certain level of tension that has been applied to the strap by the tool. It also features a resetting means for resetting the tool after the cutting action to a position where the tool can be used again. It further features a non-tension responsive cutting mechanism so that either the quick release tension related operating mechanism or the non-tension related mechanism may be selected to cut the strap.Type: GrantFiled: February 6, 1989Date of Patent: August 14, 1990Assignee: Malco Products, Inc.Inventors: James K. Rancour, Lester N. Smith

Patent number: 4315361Abstract: A duct reinforcement and a method for building the reinforcement including a special tool for use in a preferred method are disclosed. The duct reinforcement icludes a support washer on each of two opposing sides of the duct to be supported and a stiff wire extending through the sides of the ducts and both washers. The portion of the wire protruding beyond each support washer on the outside of the duct forms a hook with a tip of the wire substantially opposed to the outer face of the respective support washer. A preferred form of the support washer forms a volcano-shaped contour surrounding the washer hole on the outer face so that the tip of the wire makes contact with the washer inside the crest of the volcano-shaped contour. A preferred arrangement includes a rubbery seal between each support washer and the respective side of the duct to prevent leakage from the duct.Type: GrantFiled: June 30, 1980Date of Patent: February 16, 1982Assignee: Malco Products, Inc.Inventor: Ray G. Brooks
