UNITED STATES JOHN PORTEOUS, OF-OINOINNATI, OHIO.
IMPROVEMENT IN COMBINED PRESSURE AND VACUUM VALVES Specification forming part of Letters Patent No.7115,982, dated June 13, 1871.
I, J onN PoR'rEoUs, of Cincinnati, Hamilton county, State of- Ohio, have invented a new and useful Pressure and Vacuum Cock or Safety-Valve, of which the following is a specification:
Nature and Objeetsof the Invention.
The subject of this invention is a safety device or appendage for steam-generators, and especially for the form of them known as kitchen-boilers; and comprises an outlet-valve which is held to its seat by a spiral spring, ad-
General Description with Reference to the Drawing.
- Figure 1 is an axial section of a safety valve embodying my invention. Fig. 2 is a trans- 7 verse section at the line X X.
A is a hollow plug or barrel, adapted to be screwed into the vessel or generator at its screw-threaded portion'a. A suitable distance from its point of insertion the barrel A is enlarged interior-1y to form a seat, B, and chamber O, for an outlet or pressure valve, D, which valve is confined to its seat with any desired force by means of a spiral spring, E, whose stress is increased or diminished by the screwing inward or outward of a tubularfollower, F, confined by a cap, G, which screws onto the outside of the barrel. A ring or gland, H, and the cap Gr constitute a stuffing-box. A.
nozzle, I, which opens from the side of the barrel, permits the escape of steam or water, as the case may be. Wings J serve to guide the valve D to an atrial path in opening and closing. The valve D is hollow, and terminates below in a flaring opening to form a seat for an inlet or vacuum valve, K, that is held to its closed position by a small spring, L, that bears against the interior extremity of the valve D at one end, and at the other end bears against a nut or follower, M, that is screwed down upon the valve-stem 70 until the desired stress of spring is obtained. Orifices d in the side of the valvestem d permit the free passage of air to the interior of said stem.
