Patent number: 4709939Abstract: A centering mechanism is provided for the front wheels of a wheelchair having pairs of front and rear wheels. The centering mechanism has particular applicability for racing wheelchairs, such as those used in marathon racing. Linkage is employed to form a parallelogram structure with hinged corners, upon which the front wheels of the wheelchair are mounted by means of stub axles. The linkage holds the front wheels mutually parallel to each other while the centering mechanism returns the front wheels to parallel alignment with the rear wheels upon release of a steering device.Type: GrantFiled: November 3, 1986Date of Patent: December 1, 1987Inventor: Raymond Stewart

Patent number: 4463529Abstract: Articles are disclosed for use in providing both water-proofing protection to a foundation wall, and a support system for decorative landscaping material around the perimeter of a building. The article is in the form of an open pan having a waterproof and substantially impervious bottom, a continuous back-wall; a front-wall including perforations, and a pair of side-walls. The pan is used by placing it adjacent to a foundation wall at ground level with its back-wall abutting the foundation wall, its bottom on the ground at grade level, and its perforated front-wall spaced from the foundation wall. Additional pans may be placed adjacent to the pan at one or both of its side-walls.Type: GrantFiled: March 9, 1983Date of Patent: August 7, 1984Inventors: Ronald E. Singer, Raymond A. Stewart
