113,137. Anderson, D., and Snell, C. Scott-. Feb. 7, 1917. Vacuum engines.-A piston a is withdrawn from a cylinder b by rotating a shaft h by means of a hand-lever and ratchet gear m, or by an electric or other motor, and drives through a train such as o-v, when it is released by a brake 11 or domestic or other apparatus. Speed is controlled by a governor 8. The piston is packed by a flexible diaphragm d, and it carries an automatic air-release valve 20 which may be submerged in liquid. A ring e in the cylinder reduces clearance. When an electric motor is used to lift the piston, it is stopped automatically at the end of the piston stroke.
