AUTO MATIC. VALVE.
SPECIFICATION forming part @f .Letters Patent'. No. v705,344, dated July 22, 1902. Applioatiionled October 28, vl'lOIl.` Serial'No.-80,32 7. (No model.)
To all whom, t may concern: Be it known that wepnARLnsW. HALL,
Jr., and BENNET J. BERWAL'D, citizens of the United States, residing'` at Bradford, in the county of McKean andState off-Pennsylvania, have invented certain new and useful Im; provements in Automatic Valves; andpWe do hereby declare the following to be a full, clear, and exact descriptionof the invention, such Io as will enable others skilled in the art towwhich it appertains to make and use' thesanne'.v Our invention relatesto automatic valves for use in connectiongwith'automatic Water-- followingi description'and'claims and said :invention is' fully disclosed in 4 the .25 Referring to the said drawing,`the figure represents al vertical sectional view of our improved valve. s y. A. In the drawing, A represents the casing of our improved valve, which may be made lin 3o onc'or more parts, as desired, and comprises two chambers-a Water-chamberB,preferably located inthe upper part of the casing, and
a gas-chamber C, located, preferably, below the Water-chamber and'separated therefrom 3 5 by a slightly-flexible diaphragm D, 'of metal or other suitablematerialg The Water-chamber B is providedwith an inlety b, to be con-U` nected With the Water-main, and Withan o'u't-sl let b', to be connected with an automatic Wa- 4o ter-heater of any desired form. The upper part of the Water-chamber is in the form of a cylinder b2, in which is located a piston E, ar-
ranged to work in said cylinder, and the out let b' is in. the Wallet1 said cylinder and'vso ar ranged that when the piston" is in its lowest position it will close said outlet, as shown in the drawing.
b3l represents an auxiliary outlet-passage formed in the Water-chamber and connecting 5o the part of cylinder b2 above the piston directly with the outlet b', as shown. A The head l of thepislton E is also provided with a relief Vaperture e and valve e, said valvevbeing preferably so constructed as to remain open when the pressure of Water is equal on both sides ofthe pistonfhead. In this instance the valve "e islocated on the-lower side of vthe pistonheadand'` has its stem extending through aperture e and provided with a retaining device e2 onl'the upper side of said head, the valve being adapted to hang downwardly in open positionby its own weight when the pressure isleqnaliz'ed' above and below the piston.
The gas-chamber is provided withan inlet c, to `be connected with the gas-main, and an outlet c', to be connected with the burner of the automatic water-heater, and said chamber'is also provided with a partition c3, in
-Which an'ap'erture c4 is arranged.
` C is the gas-valve, of large area and located 7o on the side of said partition c3 adjacent to the main, said valve closing the'aperture c4 and beingheld'normally in"closed position by the pressure' of" the' gas from the main. The valve Ois provided onfthe side adjacent to the Water-'chamber with a stein c, passing through the partition or diaphragm D, and provided with nuts c8 and packing-Washers c? tovpreventleakage. The valve C is also preferably provided with 'a -stem c5, extending on the side'opposite the water-chamber and engaging a guiding-recess cinlthe'casing A to assist in bringing the valve always squarelyupon its seat.'` p
Within :theWaterchamber' the stem cs of 85 the gas4valve`is connected withthe piston E,
preferably in such manner that the movementof the'valve will be lessthan that of the piston. lIn this instance a lever F is pivoted toa-bracket f, secured to the casing A, and said lever is pivotally connected between its ends to the stem cG of the gas-valve. The other end of the lever F is connected by a link f with the piston. Y
The operation of the valve: isasfr follows: supposing the water-pip es, lea`ding from the heater to be closed, the pressure in the waterchamber will be equal above and below the piston, and the pressure of Water above the diaphragm D and of gas in the gas-chamber above the valve C Will hold it in closed position. If a Water-cock connected with the ICO heater is now opened, the pressure of water above the piston E will be lessened, owing to the auxiliary outlet-passage b3, and the pressure of the water below the piston will close the relief-valve and raise the piston, thereby opening the outlet b' and raising the gasvalve olf of its seat, and thus supplying water and gas simultaneously to the heat-er. \Vhen the draw-o cock is again closed, the pressure on both sides of the piston is again equalized, the relief-valve will open by its own weight, and the pressure of water above the diaphragm D and of gas upon the gas-valve will close it, thereby drawing down the piston and closing the water-outlet b'.
It is to be observed that should there be a leak or break in the water-main before it reaches the valve it could not in any way affect the valve, as the pressure of gas on the gas-valve would hold the parts in the positions shown. It is also to be noted that there are no springs in the construction to get out of order and interfere with the proper operation of the valve.
What we claim, and desire to secure by Letters Patent, is-
1. An automatic valve comprising among its members, a water-chamber, a gas-chamber, a diaphragm separating said chambers, said water-chamber being provided with an inlet and outlet, a piston working in said chamber and adapted to normally close said outlet, when at one extreme of lnovement, and to be moved to open said outlet by the pressure of water in the chamber, said gas chamber being provided with an inlet, an outlet, and a controlling-valve connected to said diaphragm adapted to be held in closed posilion by the pressure of gas in said chamber, and the pressure of water on said diaphragm, and connections from said piston to said gaseontrolling valve, substantially as described.
2. An automatic valve comprising among its members, a water-chamber, a gas-chamber, a diaphragm separating said chambers, said water-chamber being provided with an inlet and outlet, a piston working in said chamber and adapted to normally `close said outlet, when at one extreme of movement, and to be moved to open said outlet by the pressure of water in the chamber, said chamber having an auxiliary passage from the outlet to the side of the piston opposite that exposed to the water-pressure and a relief-vent in said piston adapted to communicate with said passage, said gas-chamber being provided with an inlet, an outlet and a controlling valve connected with said diaphragm and held normally in closed position by the gas-pressure in said chamber and the pressure of water on said diapl1ragm,and connections between said piston and said gas-valve, substantially as described.
3. An automatic valve comprising among its members a water-chamber, provided with an inlet and outlet, a piston in said chamber normally closing said outlet, and adapted to be moved by the pressure of water below the piston to open said outlet, said chamber being provided with an auxiliary passage from the other side of the piston to said outlet, a normally open relief-valve in said piston, adapted to be closed by the pressure of Water below the piston, a gas-chamber, a diaphragm separating the gas-chamber from the waterchamber, a gas-controlling valve in the gas chamber connected with said diaphragm and held normally closed by the pressure of the gas from the main and the pressure of water on said diaphragm, and connections between said gas-valve and the piston in the waterchamber for opening the gas-valve, and a connection between said diaphragm and said gasvalve, substantially as described.
4. An automatic valve comprising among its members, a water-chamber and agas-cham ber each provided with independent inlets and outlets and a diaphragm separating said chambers, said water-chamber having a cylinder, a piston working therein and arranged `to close the outlet when at one extreme of movement, said water-chamber having an auxiliary passage from said cylinder, above he piston, to said outlet, a relief-valve in aid piston held normally open by its weight nd adapted to be closed by pressure of water in the chamber, a gas-valve in said gaschamber normally held closed by the gas-pressure in said chamber and the pressure of water on said diaphragm, a lever connected to said gas-valve, and also connected to said piston, and connections between said diaphragm and the gas-valve, substantially as described.
