Abstract

27,514. Vuilquin, F. A., and Soc. Anon. des Etablissements Weyher & Richemond. Dec. 16, A.D. 1902, [date appliedfor under Patents Act, A.D. 1901]. Piston valves; actuating valves. - The regulating piston valve A, B, C, Fig. 3, of a portable steam fire - engine is connected through linkage G, H, J, Fig. 1, with a spindle L operated by a lever, or by a hand-wheel r and worm gearing ; the intercepting piston valve 4, Fig. 6, may be operated by the slotted end of the link H engaging with a pin on its operating-lever, or by a hand-operated shaft 10 and rods 12. When using the engine as a single-expansion one, the valve A, B, U is moved to the left so as to open an admission port Y of the low-pressure cylinder to the boiler-steam pa,- sage P in addition to opening an admission port T of the high-pressure cylinder. At the same time, a piston valve 4, Fig. 6, balanced by pistons 6, 7, is moved so as to close communication between the exhaust passage 8 of the high-pressure cylinder and the admission passage 9 of the low-pressure cylinder and to open the passage 8 to the atmosphere.
