Example of a dead lift cushioned pump valve and seating, patented by Thomas Downie, Liverpool, England, 1901
This form of valve, for air or water pumps, was patented by Mr. Downie in 1901. The valve is stamped from sheet metal, and has a long boss at the centre which acts as a guide, and a turned-up edge which stiffens the valve and allows water to accumulate, thus forming a cushion. A central stud projects from the valve seating, and on this a flat guard-plate is fixed to limit the lift, it being bored out to accommodate the valve boss.
