Abstract

145,790. Rahardt, E. July 2, 1920. Planing.-Parquetry scrapers propelled by compressed air motors are controlled by two rotatable hand-grips a, b, at the ends of the guide-bar c, the grip a serving to control admission of air to the motor and the grip b to actuate the reversing- valve. Air passes through a pipe e and the support d of the bar c to the motor, and is controlled by a valve l adapted to be actuated by a cam-slot i in the grip a. The grip b actuates the reversing-valve through a rod n pivoted to it, and is retained in either of its two positions by a detent u against which it is pressed by a spring s.
