  • Patent number: 5713258
    Abstract: A compound miter box is provided wherein the saw guides are pivotable about a vertical and a horizontal axis. Each saw guide includes a retaining mount having a concave bearing surface defining a locating tab thereon. A saw supporting arm is pivotally mounted to the underside of the saw bench. The arm includes a plurality of tab receiving depressions therein. Each tab receiving depression corresponds to a predetermined angle between the saw guides and the saw bench. A user may then select and secure the locating tab in a tab receiving depression corresponding to the desired predetermined angle between the saw guides and the work supporting surface of the bench.

  • Patent number: 5560273
    Abstract: A miter box is provided with a simple demountable and adjustable board stop which operates in conjunction with the horizontal upper edge of the miter box backstop to position a board, such as a piece of cove molding, in an acute vertical angular position with respect to the miter box table which allows the board to be cut at the compound angle required for a mitered butt joint in which the cut pieces are mounted at the same relative angle in which they are positioned in the miter box. The box also includes a simple frictional locking mechanism to set the pivotable saw carriage in any selected horizontal angular position over the full range provided by the miter box.

  • Patent number: 4513466
    Abstract: A plastic housing shell has two spaced apart bosses in it and first and second shafts extend in parallelism from the bosses. A turbine rotor has a bore that fits loosely over the first shaft and has a concentric first pinion with the same oversized bore. A gear and an integral pinion are journaled on the second shaft. The gear meshes with the pinion on the turbine rotor and the pinion on the gear meshes with a gear on a base ring of a rotary brush. The gear on the brush ring has a bored cylindrical shaft extending axially from it which slips over the first shaft for the brush to rotate on it while the periphery of the cylindrical shaft fits into the bore of the pinion and rotor so the rotor is journaled on said cylindrical shaft. Springy latch prongs engage a cover through which the brush extends so said cover retains all of the brush assembly parts in assembled condition. No other fasteners are required. A conduit that supplies the water jet for driving the turbine serves as a handle for the brush.

  • Patent number: 4458963
    Abstract: A tool caddy and stool resembling a hollow truncated pyramid that has a rectangular base which is longer than it is wide and a platform top constituting the truncated end. The platform is supported from columns extending from the base and inclined similarly to the sides of a pyramid. The base has a floor which is compartmented for storing items. A shelf or reel for storing an extension cord is removably supported in the caddy. The platform has holes for passing a hand through for carrying the caddy.

  • Patent number: 4428266
    Abstract: A frame for holding a mitering saw blade has an end member in which there is a longitudinally extending hole whose axis is spaced from and parallel to the blade. The hole serves as a bearing. The saw handle has a shaft extending from it. The shaft is journaled in the bearing hole and secured against withdrawal. Thus, the frame and handle can swivel relative to each other about a longitudinal axis.
