Abstract: Apparatus for and method of cleaning carpet or the like in conjunction with a vacuum source and a source of pressurized cleaning fluid. The apparatus includes an elongate handle to which is attached a cleaning head. The cleaning head includes a forward wall and a striker plate disposed in generally parallel relationship to form a vacuum chamber. A nozzle assembly for dispensing the pressurized fluid is carried by the cleaning head so as to direct the fluid against the striker plate at a point above the carpet surface. Alternative embodiments include the addition of one or more brushes disposed in front of the striker plate. The method includes so directing the fluid so that it is drawn around the edge of the striker plate, through the pile of the carpet and into the vacuum chamber as the apparatus is moved across the carpet.

Abstract: An improved disc brake member is disclosed wherein the periphery of the usual carbon or graphite disc is covered with a metallic covering member which is secured thereto by axially extending pins which are pressed in place and then welded to the covering member. The invention also includes constructing the covering member in a number of segments, with clips being interposed beneath the ends of the segments so that the longitudinal ends of each segment can be spaced from the longitudinal ends of the next adjacent segment. In this fashion, a complete covering of the critical area of the brake member is achieved, while expansion due to heat build up is permitted. Further modifications include recessing the covering member to present flush planar side surfaces, and fusing the pin itself into the grain structure of the disc.
