Abstract: A mounting arrangement for allowing a variety of circular grinding, sanding or stripping devices to attach to the same power source having a spindle drive shaft. The devices are substantially enclosed by a rigid guard housing and adjustment means are provided to change the angle of the housing with respect to the drive shaft, thereby changing the amount of exposure of the devices to the work surface. The rigid housing is mounted at a fixed axial position on the shaft and is free to rotate relative to the drive shaft. A mounting shaft is attached to the drive shaft on one end thereof and to a resurfacing device on its other end. A bearing allows the mounting shaft to rotate relative to the housing. A support plate is attached to the housing and to the drive shaft.

Abstract: This invention is a tool for simultaneously resurfacing by cutting the face and overlying butt portions of shingles or clapboards forming the outside surface of a house or the like.

Abstract: A tool for form engaging and turning components such as nuts, bolts, and screws. In its basic form, it includes a chamber which in turn supports a bundle of pins each of which is adapted to slide further upwardly into the chamber when the lower pin end contacts the component at the lower end of the housing.

Abstract: A rotary blade for a resurfacing tool. The blade has two or more sets of teeth extending essentially perpendicular to the plane of the main disk of the blade. The teeth of varying rows are configured to perform either a rough first cut or a smooth finish cut or a cut inbetween. The blade is oriented in such a manner as to allow for a rough cut to a set depth followed by a smooth cut to a slightly greater depth.

Abstract: A tool for simultaneously resurfacing by cutting the face and overlying butt portions of shingles or clapboards forming the outside surface of a house or the like. The tool includes a housing in which a rotatable cutting disc is mounted for rotation such that two different cutting surfaces can simultaneously engage the surface, that is, the aforementioned clapboard or shingle surfaces simultaneously. The housing includes first guide means to separately position a series of first cutters such that the major face of the work surface is cut to the desired depth and separate second guide means to simultaneously regulate the depth to which the second cutters may engage the overlying or butt portions of the shingles or clapboards forming the work surface.
