Abstract

586,248. Actuating machines. EVANS, F. H. Dec. 6, 1944, No. 24432. [Claas 83 (iii)] [Also in Group XXIII] In fluid-operated means for controlling the feed of a machine, a piston 13 working in a compressed-air cylinder 12 is connected to a piston 19 working in a cylinder 18 of liquid fed from a reservoir 24, the port 20 passing the ejected liquid during the working stroke and being controlled by a valve 21. A port 23 allows rather free ejection of the liquid on the quick-return stroke whilst a further port 25 restricts the flow when the port 23 is covered by the piston to cushion the return stroke. The port 23 also allows liquid to flow back into the cylinder at the end of the feed stroke.
