Abstract
541,083. Dashpots. E.M.B. CO., Ltd., and CATLIN, L. A. May 9, 1940, No. 8375. [Class 108 (iii)] [Also in Group XXVI] A device for preventing sudden rapid movement of a pneumatic press in either direction, as in broaching when the load is relieved by completion of the work, a piston c connected to the press piston moves in a cylinder a secured to the head of the press and its ends are connected to a liquid reservoir f by passages g each controlled by a manually adjustable valve i having a transverse bore r which thus varies the flow of liquid into the reservoir. Liquid returns to the cylinder a through check valves t controlling bores w leading to the bores r.
