Abstract: An apparatus and method for cutting wallboards, such as gypsum wallboards or rock wallboards to an appropriate size and shape, and for locating utility boxes hidden behind a panelled wall and cutting of a section of the wall at the opening of the utility boxes. The apparatus of the invention comprises a portable hand tool having an adjustable rest for adjusting the depth of cut and a built-in ruler-guide arrangement permitting to cut parallel to a side of a wallboard or permitting to cut circles in a wallboard. The hand tool may be used in combination with a separate locator and cut-out template member positioned in utility boxes mounted behind an installed wall, which provides an indication of the location of each utility box by way of a wallboard puncturing prong, for cutting out an opening in the wallboard, following appropriate guide grooves in the face of the locator and cut-out template.

Abstract: A molding curvature template fixture is disclosed. The fixture (10) holds a strip of molding (16) and provides a template for a portable router to follow to shape an end of the strip of molding substantially similar to the cross-sectional shape of the shaped side of the molding (16). The molding (16) can then fit over the shaped side of an adjacent, perpendicularly-disposed strip to form a right angle joint. The fixture (10) is comprised of a box-section frame (12) having a series of lateral slots (26, 28, 30, 32, 34) and a clamping mechanism (14). Each slot (26, 28, 30, 32, 34) includes a guiding surface having a shape substantially similar to the cross-sectional shape of the shaped side of a strip of molding (16). An insert (50) may be attached to frame (12) to provide a guiding surface for cutting molding having a non-standard shape.

Abstract: A template device for guiding a cutting tool in cutting engagement with a surface of a work piece to provide ornamental design in the surface of the work piece.

Abstract: The invention comprises an improved ice skate grinding, sharpening and contouring machine. The machine includes novel means to accurately center an ice skate between the heel and sole struts in a movable holding fixture and means to select the best contour position on the blade as a function of intended skate usage. As an example, the best blade contour for a hockey forward requires a deeper grind below the forward strut than the contour for a hockey defenseman. The centering feature assures that the skate contour desired will be accurately ground onto the blade and pitched forward the desired amount. Means to adjust the blade position relative to the blade holding fixture for pitching are disclosed in one embodiment. In an alternative embodiment means for pitching the entire fixture as desired are disclosed. Figure skates can be advantageously centered and pitched as desired with the invention for accommodating the particular requirements of the figure skater.

Abstract: A tracer mechanism having a stylus to scan the surface of a pattern or a template and to cause a congruent relative movement of a cutter and a workpiece, whereby to reproduce the contour of the pattern or template in the workpiece. The stylus is provided with an axial force element which can adjustably vary the endwise thrust of the stylus, thereby to vary the reaction force of the stylus against the workpiece. As a consequence, the stylus can be caused more accurately to track the pattern or template along a tracing plane, especially on a pattern which has a steep slope that tilts laterally relative to the tracing plane. Means is also disclosed to utilize the axial force element in a machine tool table control wherein a "box-cycle" movement is made in which the cutting tool is withdrawn from the workpiece, is stepped to a new tracing plane, and is returned in a non-cutting motion to the starting point of a subsequent cutting movement parallel to the first one.
