Abstract

281,369. Asquith (1920), Ltd., W., Feather, G., and Howden, P. Aug. 30, 1926. Drawings to Specification. Driving machines.-Revolving-spindle metalcutting rnachines such as radial and other drilling- machines, boring-machines, milling-machines, and the like are driven by electric motors fed by variable-voltage generators, means being provided such as series resistances or potentiometer resistances to vary the strength of field in both the generator and the motor for the purpose of speed variation. Switches or equivalent electrical means are provided for reversal. For radial drilling-means an electric drive of the above kind replaces the customary vertical driving shafts and variable ratio gears.
