Abstract

334,558. Burstall, F. W. March 5, 1929. Screw threads, grinding; wheels; gauges; trueing rotating tools.-In the precision winding of the threads of screws, screw plug gauges or taps, the bottoms of the threads are finished by a grinding wheel j of convex profile, and the tops of the threads by a wheel k of corresponding concave profile, the wheels j and k being rigidly mounted on the same spindle in correct spaced relationship and being shaped in situ by the same diamond tool h. The diamond is mounted in a cranked holder g mounted in a boss of a member b<1> which is adjustable radially of the wheel on a plate e carried by a short spindle a. The spindle a is mounted in the upper part of a horizontal slide c which in turn is carried by a slide d vertically adjustable by means of a micrometer head d<1>. To shape the grinding-wheels the diamond point is moved about the axis of the spindle a and is adjusted to a position above or below this axis for shaping the convex or the concave wheel respectively. Suitable stops may be provided for limiting the arcuate movement of the diamond. A microscope such as l having cross wires m corresponding to the flats of the wheel j may be used to facilitate the adjustments. For trimming the flat sides of the profile of the wheel j an additional diamond p mounted on a hclder n may be fed by hand in relation to stationary locating members o. The spindle on which the wheels j, k are mounted is carried in a curved slide p<1>, Fig. 10, having horizontal adjustments q, r so that the wheels may be set correctly to engage the threads to be ground on the work.
