SAFETY-VALVE.
BPECIFICATION -t'orming part of Letters Patent No. 351,198, dated October 19, 1886.
(No model.)
To all whom it may concern:
Be it known that I, BIAURICIO M. MoNsANTo, a citizen of the United States of Colombia, South America, residing at New York, in the county of New York and State of New York,
have invented certain new and useful Improvements in Safety or Relief Valves; and I do hereby declarg the following to be full, clear, and exact description of the invention, such as will IO enable others skilled in the art to which it appertains to make and use the same.
This invention relates to safety or relief valves.
The object is to produce a safety or relief I 5 valve which shall be simple and economic in construction and positive and reliable in operation, and between the working parts 'of which there will be little or no friction to retard the movement thereof, the said valve to 2 0 be capable of being applied either directly to a reservoir containing fluidsuch as gas, air, steam, or waterunder pressure or to the outlet therefrom, and adapted to be operated to allow the escape ofthe fluid when an excess of pressure exists, and thus to maintain an even pressure in the reservoir, thesaid valve being capable of being adjustable to hold the fluid at any suitable pressure without allowing it to escape.
IVith these objects in view the invention consists, essentially, of the combination, with the outlet-pipe of a reservoir, steam-dome, or the like, of a valve and cylinder situated a suitable distance apart, connected wit-h said reservoir or pipe, and communicating with each other by a common conduit or by independent connections with the said reservoir, steam-dome, or pipe containing the fluid under pressure, the valve being joined to the 40 piston of the cylinder by an operating-lever provided with an adjustable weight, which tends to keep the valve closed,whilc the pressure of the fluid, acting upon the area of the piston in the cylinder, tends to lift the valve, 4 5 opening it, so that as the piston moves up and down the valve is opened or closed, the parts being of novel and advantageous form; and, further, the invention consists in various novel details of construction combined, as will be clearly hereinafter set forth.
In the accompanying drawings, Figure 1 is a central longitudinally vertical section of a portion of the outlet-pipe from a reservoir, steam-dome, or the like, in which fluid is held under' pressure, exhibiting my relief device. Fig. 2 represents a similar view of a modified form of my relief device for valve, the same being shown as connected directly with a reservoir, steam-dome, or the like.
In the drawings, A represents the outletpipe, which is connected at any suitable point to the reservoir in which the fluid is contained.
B represents a cylinder which is placed in the outlet-pipe from the reservoir or pipe containing the fluid under pressure, and through which cylinder the fluid passes from the reservoir. This cylinder may be set in the circuit or outflow from the reservoir containing the fluid under pressure, so that said fluid may escape or flow from said reservoir past the piston on which it acts, and thence through the relief-valve opened; or the cylinder may be directly connected or connected by a pipe from and communicate with the said reservoir, but have no communication with the valve by conduit, but the escape of the fluid through the valve, when opened, be by means of a pipe or connection communicating with said reservoir independently of the cylinder. In the cylinder B is a piston, G, provided with the projection O, which extends upward beyond the pack ing of the cylinder, and is provided with a bifurcated end, in which is mounted a roller, 0, upon which bears a lever, D; or said lever may be otherwise suitably connected with said piston. 0 represents a button or projection at base of piston, or it may also be at base of cylinder to insure pressure at base of piston. E represents a valve-chamber,which is placed in an outlet-pipe from said reservoir a suitable distance from the cylinder B. This chamber contains a valve, F, which consists of the two portionsf andf, connected by a rod,f The valve F is provided with the upward-extending stem f 3 and the downwardcxtending stem f. The lower stem enters a socket, e, in the lower portion of the valve-chamber, in which it slides, and by means of which it is retained in its proper place and guided in its movement up I ber.
and down. The upper stem,f is pivotally connected with the operating-lever D, by means of which it is moved up and down. The outside of the valve-chamber is provided with the rigid guidingarm e and the pivoted arm 6 To this latter the end of the operating-rod D is pivoted.
The valve-chamber E is provided with two ports, E and E, so arranged that the lower wall of the'upper chamber forms the upper wall of the lower chamber; and the opening or diaphragm in the same forms the seat for the valve Fff- Thus it will be seen that the wall referred to forms what is practically a dia phragm, which, in connection with the valve, affords means of allowing, reducing, or stopping the flow of fluid through the valve-cham- E represents a vent in the side of the valvechamber, situated below the portion fof the valve, the purpose of which opening is to admit air below the valve for the purpose of compensating for the atmospheric pressure on the upper portion of the valve, likewise for the escape of any fluid which may leak through the packing of the lower piston, f.
The pivoted lever D, which is connected to the piston-rod and the valve, is provided with the movable and adjustable weight D, which tends to keep the valve closed, having a setscrew, D by means of which the said weight may be secured to the lever at any desired point to regulate the force necessary to be exerted upon the piston to raise it and thereby open the escape-valve. The nearer the weight is placed to the point at which the lever is connectedto the valve, of course the easier it will be to raise the said lever, and vice versa.
In Fig. 2 of the drawings I have illustrated a modified form of my safety-valve, which is adapted to be placed directly upon the reservoir, steam-dome, or the like, instead of upon any outlet-pipe therefrom. In this form the cylinder B and valvechamber E are each connected directly (but communicate independently) with the body of the receptacle, and the pressure of the fluid contained therein is exerted directly upon the piston O, and is communicated to the operating-lever D, by means of which the valve is operated. In order to simplify the construction of this modified form, the valve is so arranged as to be depressed when an excess of pressure exists in the reservoir, thus forming an opening around the top of the valve-chamber. The interior of the valve-chamber com municates directly with the reservoir or dome, and it is provided on the inside with a cylinder, H, suitably c011- nected by radial arms with the wall of the valve-chamber E, in which the valve-body F moves up and down, being provided with the packing suitable for the fluid to be used, and
is also provided with a circular internal passage between said cylinder H and the outer wall of the valve-chamber E for the escape of the fluid from the reservoir when the valve is depressed, and thereby an opening through the diaphragm madeinthe top-of the chamber.
When the valve is in a closed position, its upper end, which is slightly tapering, presses against the upper end of the valve-chamber, which forms the valve-seat, the opening in which is slightly flared in order to form a close joint with the valve. Inasmuch as in the modified form of the valve the valve proper has to be depressed in order to allow the escape of the fluid, instead of raised, as in the preferred form, the operating-lever is pivoted between the points at which it is joined to the operating-piston and the valve, instead of beyond, where it isjoined to the valve, as in the preferred form, to raise it, as shown in Fig. 1.
It will, of course, be understood that although I have particularly described the construction and arrangement of my improved safety or relief valve, various modifications thereof other than that shown may be employed without departing from the spirit of my invention.
Having thus described my invention, what'I The herein-described safety-valve, consisting of the combination, with the outlet-pipe, of the cylinder, the balanced valve, and the piston, each communicating with the fluid under pressure in a reservoir, and an operatinglever connecting the piston of the lever and the valve, the said lever being connected with an" adjustable weight, whereby the degree of pressure necessary to operate the valve is regulated, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
