    摘要： A surface leveling tool for sanding wooden, painted and plastic surfaces without gouging. The tool comprises a handle of variable length attached to a head with a clamping element which holds a flexible plastic sandpaper insert. A specially formatted sandpaper sheet is adhered to the flexible plastic insert. The plastic insert has a cross-section analogous to a J-shape and is clamped only by the hooked portion. This arrangement provides for space between the unclamped portion of the sandpaper covered insert and the clamp. The clamp utilizes fasteners which are tightened. and loosened by a hidden screwdriver in the grip of the handle.

    摘要： A method and apparatus for grinding a workpiece which is supported for rotation about a first axis with a first grinding wheel supported for rotation about a second axis and a second grinding wheel supported for rotation about a third axis. The first grinding wheel engages with the workpiece in a location which is substantially diametrically opposed to the location at which the second grinding wheel engages with the workpiece. Control means are disclosed for controlling the radial grinding force imparted to the workpiece by the first and second grinding wheels so that the force imparted to the workpiece from the first grinding wheel is substantially equal and opposed to the force imparted to the workpiece by the second grinding wheel to prevent distortion of the workpiece.

    摘要： A centerless valve regrinder for resurfacing a worn valve having a face, a tulip connected to the face, a valve stem connected to the tulip, the stem having an axis, a first notch worn into the stem at a location spaced from the tulip, and a second notch worn into the stem at a second location spaced from a distal end of the stem. The regrinder is comprised of a power-driven means for resurfacing said valve face, and a chuck for supporting the valve stem in such an orientation as to cause contact between the valve face and the means for resurfacing at the angle of bevel of the valve face. The chuck is also comprised of a wheel for rotating the stem about its axis and simultaneously drawing the valve face into contact with the means for resurfacing. The chuck is further comprised of two fixed supports that are in parallel orientation and of sufficient length to cradle and support the stem from respective points adjacent the tulip to respective points past the first notch, and preferably past the second notch. Preferably, there is no stop member to contact the distal end of the stem to limit the regrinding.

    摘要： There is provided a valve grinding apparatus for centerless grinding of valves. Two base rollers with parallel axes are driven, and a control roller is centered above the base rollers. The control roller can be raised and lowered and the direction of its axis can be changed in order to cause the valve to be moved longitudinally in either direction. A support means is spaced from the base rollers and supports a different region of the valve stem.
