Abstract:
Disclosed is an apparatus for cleaning the hard-to-reach lower surfaces of the upper platens of large consolidating presses. The apparatus comprises an upwardly-facing rotary abrasive disk driven by an air motor mounted in a housing having an elongated hollow handle with an operator-controlled air supply valve thereon. The motor housing is slidably mounted on a frame including telescoping height-adjusting legs which extend upwardly from a rectangular base having downwardly extending portions at each end thereof with a roller mounted to extend therebetween to stabilize the apparatus and allow it to be used in even the critical edge portions of presses with safety. Holes in the telescoping legs, adapted to receive self-locking, quick-release pull pins are provided to facilitate adjustment and retention of the apparatus at the desired height.
