Abstract

19,193. White & Co., J. S., and Wright, H. T. Aug. 23. Actuating; rotating to ensure even wear. - In an internal-combustion engine, the inlet or exhaust valve a is worked by a grooved cam f, g, which, after the valve is closed, draws back the tappetrod k so as to compress a helical spring r between washers q, o, on the tappet - rod and valve stem respectively, causing partial rotation of the valve. The spring r may be attached to the washer o
