Abstract

311,731. Jopp, R., Jopp, A., and Jopp, C., (trading as Jopp, A., [Firm of]). May 15, 1928, [Convention date]. Disc apparatus ; guides ; wheels. - A machine for grinding simultaneously two opposite surfaces of prismatic articles, for example, nuts, consists of a table 2 on which are mounted pairs of slides 5 adjustable by screws 9 and carrying hollow spindles 7, the number of pairs of slides corresponding to the number of pairs of faces on the work. Secured on the spindles by bolts 13 having heads 14 and by nuts on the outer ends of the bolts, are grinding-wheels consisting of concentric cylinder 16, 17, the outer cylinder being of coarse grain, and the inner of fine grain, the operative faces of the wheels being conical, and the spindles being inclined as shown. The nuts are introduced into a tube 18 between the pairs of grinding-wheels, the internal cross-section of the tube corresponding to the shape of the nuts, and are fed forward by the wheels, which contact with the nuts below the axes of the wheels, openings 20 being provided in the tube opposite the wheels. Between the pairs of wheels the tube is twisted so as to turn the nuts to present new faces to the succeeding pair of wheels; the coarse-grained cylinder 17 acts first on the nuts, the fine-grained cylinder 16 then giving a fine grinding.
