Abstract

582,833. Work-holders; jigs. WHITEHOUSE, J. C. Sept. 4, 1944, No. 16779. [Class 83 (iii)] [Also in Group XXIII] A work-holder comprises a rectangular-, preferably square, block 10 having four cylindrical feet or rolling surfaces 13 terminating the edges of the block, a central bearing 15 and means for clamping a work-piece to the base block or frame, the four axes of the cylindrical feet being parallel and located at the corners of a square or other rectangular figure in a plane normal to the axes and all the feet being of the same radius withtheir freely accessible cylindrical surfaces extending for more than 45 per cent on each side of a diagonal of the figure locating the feet. The feet are located in rectangular recesses 11, joined with the edge faces of the block by bevels 12, and are held in position by screws 14. A central bearing aperture' 15 formed in the block is adapted to engage over a spindle 19 projecting from a pedestal 20 with which the device may be used. Each side of the block has inclined rows of tapped work-clamping holes 16 and each edge face has tapped holes 17 by which setting plates 18. may be secured. Fig. 7 shows the device in use on the table 22 of a drilling machine. The pedestal 20 is supported horizontally by a block 23 and the work 21 clamped to the block 10 is adjusted by means of slip gauges 25 supporting the cylindrical feet 13 in the manner of a sine-bar. Similarly, holes 26 could be drilled by suitably supporting the pedestal 20 in relation to the tool. The device may be used for grinding arcuate surfaces by manually rocking the block 10 about the spindle 19 within limits determined by stops engaging the feet 13.
