Abstract
364,592. Fluid actuated valve gear. SULLIVAN MACHINERY CO., 400, North Michigan Avenue, Chicago, U.S.A. June 30, 1930, No. 19794. Convention date, July 5, 1929. Void [Published under Sect. 91 of the Acts]. [Class 122 (ii).] In order to use pressure air to blow cuttings out of a rock drill bore hole, the distributing valve 32 is held in its forward position by the plunger 58, which is moved by a cam-shaped portion of the control valve-22. In this position air passes continuously from the supply 21, through passages 66, 26, 29, 34 to the forward side of the piston and thence through the hollow drill steel. A notch 65 is formed in the control valve, into which the plunger 58 fits in the closed position to prevent accidental starting.
