Abstract

129,955. Richardson, L., and Hopkinson & Co., J. April 23, 1919. Actuating - mechanism.-In a parallel slide stop valve of the kind operated by a rack and pinion, as described in Specification 777/09, the rotary movement of the operating spindle B is limited by a fixed stop G formed on the packing-gland E acting in conjunction with the known stop projection J on the spindle. The stop members are disposed in a recess H of the casing A which can be readily machined for that purpose.
