Abstract

200,197. Dickson, A. S. April 7, 1922. Steam &c. hammers.-In a hammer with a lifter cylinder fitted with a semi-rotary piston, an expansion valve 14 operated by a cam 17 on the shaft 6 and levers and links 19, 19<a>, 23 is arranged between the hand-operated valve 10 and the supply main, and acts to cut-off the fluid supply before the piston 5 over-runs the exhaust port 8.
