Abstract

410,779. Grinding valves. DAVIDSON, G. W., 2, Alpha Terrace, Broughty Ferry, Dundee. Nov. 16, 1932, No. 32345. [Class 60.] A valve-grinding machine is provided with means, such as a crutch or cradle C, for securing to it the body of an electric or other portable drill which rotates the driving shaft E of the machine. In the apparatus shown the crutch C is adjustably mounted on a bar B carried in the base of the apparatus, allowing the drill to be adjusted so that the chuck may grip the shaft E, which is attached by a universal joint to a double pulley D. Belt drives from the pulley D rotate a spindle G, carrying the grinding wheel H, and a spindle I carrying a spring collet which holds the valve, the spindle I being carried on a slide movable towards and from the spindle G by a screw K. The wheel H is trued by a diamond carried in a housing N slidable along a bar M held in one or other of two grooves in a raised part L on the base, the grooves forming angles of 30‹ and 45‹ respectively.
