Abstract

12,507. Schneider, L. June 3. Safety-valves.-The construction is such as to prevent the valve being tampered with. The valve a is formed in one with the hollow stem A and the suitably-packed piston B, to the upper surface of which the steam in the boiler has full access by the passages b. The area of the piston is such that the steam pressure on it, combined with the weight of the whole valve, puts the valve in equilibrium at the normal pressure. The hollow may be weighted as at S, or may be pressed upon by a helical spring. The escaping steam, when the valve rises, passes away from the chambers H by the exhaust outlet F shown in dotted lines. The valve may be raised by hand by means of the spindle P and cam e.
