Patent number: 8356782Abstract: A device is disclosed for supporting an object, such as a picture frame, on a wall. The device includes an arcuate member having a penetration end that terminates in at least one point. The arcuate member further includes a support end, opposite the penetration end, that has a support hook. A pressure disk may be slidably retained at an aperture therethrough on the arcuate member. A plurality of different support accessories may be included, the support hook being adapted to support each support accessory thereon. In use, with the penetration end of the arcuate member contacting the front surface of the wall, pressure is applied to the pressure disk that binds against the arcuate member to force the penetration end of the arcuate member through the wall. The arcuate member is curved such that when the support hook contacts the front surface of the wall the penetration means contacts the rear surface of the wall to retain the device firmly in the wall and to support the object.Type: GrantFiled: November 17, 2009Date of Patent: January 22, 2013Inventors: Andre Robichaud, Clayton R. Peterson

Patent number: 7717770Abstract: An apparatus for grinding both inside surfaces of a concrete joint simultaneously is disclosed. The apparatus includes a proximal grinding wheel having a rotational axis and a grinding implement fixed with a proximal side, and an external drive shaft fixed to the center thereof. A distal grinding wheel is included that has the same rotational axis a grinding implement fixed with a distal side. An internal drive shaft is fixed partially within the external drive shaft and to the center of the distal grinding wheel. The apparatus further includes a means for moving both grinding wheels apart, a source of rotational kinetic energy, and a means for coupling the source of rotational kinetic energy to each drive shaft.Type: GrantFiled: July 8, 2008Date of Patent: May 18, 2010Inventors: Clayton R Peterson, Sandford Gray Dincolo

Patent number: 6739957Abstract: A surface abrader apparatus includes a casing, a motor mounted on the casing, one or more working tools, and an operating mechanism mounted to the casing and supporting the working tools outside of the casing. The operating mechanism is drivingly coupled to the motor for causing an impacting movement of the working tools against a workpiece in response to selected operation by the motor. The operating mechanism includes one or more elongated shafts reciprocally mounted in the casing parallel to one another and having same one ends extending from the casing, a drive shaft rotatably mounted in the casing between and parallel to the shafts and rotatably driven by the motor, and coil springs and cam elements for causing lifting and releasing of the shafts and the working tools, such as impact abrading heads, mounted on the same one ends of the shafts to produce impact movements of the tools.Type: GrantFiled: December 3, 2002Date of Patent: May 25, 2004Inventors: Clayton R. Peterson, Steve Sanders

Patent number: 5788561Abstract: A handheld and readily maneuverable apparatus for grinding floor surfaces and/or cutting grooves in a floor formed of a hard material such as concrete, stone or the like is disclosed. The apparatus includes an elongated tube having a motor mounted at its upper end and a special rotatable abrasive head at its lower end. Rotation of the motor is coupled to the rotatable abrasive head via a flexible shaft that extends longitudinally through the elongated tube. In one form of the invention, the abrasive head includes a grinding disk that is oriented generally horizontally relative to the floor when the apparatus is in its operating orientation, and the operator can manually maneuver the apparatus so as to grind the floor surface.Type: GrantFiled: June 20, 1997Date of Patent: August 4, 1998Assignee: Pearl Abrasive Co.Inventors: Gordon E. Pearlman, Clayton R. Peterson

Patent number: 5683143Abstract: An improved abrasive floor treatment apparatus that can be used to effectively treat a variety of floor surfaces, including floor surfaces that are uneven. The apparatus includes a plurality of special abrasive block assemblies that are mounted on the underside of one or more rotatable disks, with each such assembly including a mounting block that releasably retains a plurality of spring-biased abrader assemblies. Multiple configurations for these abrader assemblies are provided, each adapted for use in providing a different kind of surface treatment, and these abrader assemblies are easily and conveniently installed in the mounting block.Type: GrantFiled: January 11, 1996Date of Patent: November 4, 1997Assignee: Pearl Abrasive CompanyInventors: Clayton R. Peterson, Gordon E. Pearlman

Patent number: 4758050Abstract: There is disclosed herein a machine for removing coatings from uneven surfaces such as concrete and the like. The machine includes a power system for driving a pair of cutter head assemblies. The cutter head assemblies are rotated in opposite directions to help stabilize the machine and to throw the cuttings out of the way. Each cutter head assembly has a cutter head with a plurality of peripheral sides or facets and cutter bars are spring loaded thereon to allow cutting tools held by the cutter bars to effectively float on the concrete surface and follow uneven sections of the surface. The cutter head assemblies are mounted on the machine so that they can tilt forward and backward and from side to side to facilitate the cutter head assemblies following uneven surfaces.Type: GrantFiled: March 25, 1987Date of Patent: July 19, 1988Assignee: Equipment Development Co., Inc.Inventors: Clayton R. Peterson, James E. Ward, Leo Swan

Patent number: 4242794Abstract: A universal blower unit is provided which may be directly attached to any of the most widely distributed flexible line type grass or weed trimming tools, known as "Line-Trimmers" and sold under various designations including under the trademark "WEED EATER". The blower unit is secured to the motor housing following removal of the unit which normally holds the line employed in the line trimming operation. In securing the blower unit in place, a series of spacing studs are employed to orient and prevent lateral movement of the blower unit, and spring clamps extend up over the housing to hold the blower unit onto the motor housing and to hold the impeller in driving engagement with the output drive shaft from the motor. A small supplemental impeller is located adjacent the motor for cooling purposes. The blower unit is spaced downwardly from the motor housing and air is drawn in through the space between the blower and the motor housings.Type: GrantFiled: February 27, 1979Date of Patent: January 6, 1981Inventor: Clayton R.
