Abstract
347,243. Embossing-presses. SHAW, P. and SHAW & SONS (SALFORD), Ltd., J., Wellington Street Works, Salford, Lancashire. Dec. 24, 1929, No. 39362. [Class 100 (ii).] A hydraulic embossing-press is provided with separate valves for exhaust, low-pressure inlet, and high-pressure inlet, the exhaust and low-pressure inlet valves being operated by high-pressure liquid through pilot valves. A main valve block comprises a low-pressure inlet valve 1, Fig. 7, a non- return valve 2, an exhaust valve 3, inlets for low and high pressure at r, u<1>, and a connection to the press cylinder at r<1>. Eccentrics e<3>, Fig. 4, on a control shaft a operate through tappets j of adjustable length, a valve g<3> for controlling the highpressure supply and similar valves controlling the inlet and exhaust of cylinders w for operating the valves 1, 3.
