ABSTRACT:
A vacuum shield for an abrading device adapted for use upon non-uniform surfaces. The shield includes a general planar top housing mountable between a motor of the abrading device, such as a power stripper or sander, and its abrading element there. The housing includes at least an upper, a middle, and a lower surface, the middle surface including a first opening, through which a power shaft between the motor and the abrading element can pass. Each of the upper and lower surfaces are secured upon a separate downwardly-biased pivot axis to respectively opposite sides of the middle surface, for angular movement relative to an axis defined by the power shaft. The middle surface also includes a second opening for connection to a vacuum hose coupling. The shield further includes continuous flexible skirts depending from the entire length of opposite non-hinged edges of the middle segment. Each of the upper and lower surfaces of the top housing also include continuous flexible skirts which depend from the entire length of each on the non-hinged edges. The combination of the flexible skirts of the upper, middle and lower surfaces function to mechanically and pneumatically surround the abrading element Irregularities in any non-uniform surface to be abraded will be substantially conformed to, and otherwise enveloped by, the function of the flexible skirts and of the pivotally downwardly biased relationship of the upper and lower surfaces to the middle surface of the top housing.
