Patent ID: 8475072

Claim:
A scraping apparatus assembly for use with a pressure cleaning wand having a nozzle for emitting a fluid to remove debris from a planar work surface, the scraping apparatus assembly comprising: a scraping blade is fabricated of a planar material having at least one blade edge provided along a distal end thereof and a planar mounting section located proximate an opposite proximal end thereof; a scraping apparatus spacer block having a wand-engaging surface provided along one surface of the scraping apparatus spacer block and a planar blade-engaging receiving surface provided on a side opposite the wand-engaging surface, wherein the scraping apparatus spacer block provides a distance between the wand-engaging surface and the blade receiving surface for maintaining the wand and the scraping blade in spaced-apart relationship to one another; wherein the scraping blade planar-mounting section is assembled to the planar blade-engaging receiving surface orienting, thereby the scraping blade distal end blade edge opposite the planar mounting section, in a manner extending said blade edge beyond and forward of the scraping apparatus space block such that, during use, a bottom surface of the scraping blade distal end is unencumbered by any structure between said bottom surface and said work surface; and at least one nozzle securing clamp providing a clamping force between a surface of the respective nozzle securing clamp and the pipe engaging surface of the spacer block; wherein, during use, the spacer block maintains the planar blade between the wand nozzle and the planar work surface.
