Hydraulic Press
Bramah had designed a hydraulic press, but was having problems sealing both the piston and the piston rod where it fitted into the cylinder. The usual method was hemp packing but the pressures were too high for this to work. Maudslay came up with the idea of a leather cup washer, which gave a perfect seal but offered no resistance to movement when the pressure was released. The new hydraulic press worked perfectly thereafter. But Maudslay, who had made a major contribution to its success, received little credit for it.

Famous quotes containing the word press:
“Our presidents have been getting to be synthetic monsters, the work of a hundred ghost- writers and press agents so that it is getting harder and harder to discover the line between the man and the institution.”
