LOVELL W. COOPER, OF SCHENECTADY, NEW YORK.
AUTOMATIC STOP-VALVE.
Specification of Letters Patent.
Patented Aug. 18, 1914.
Application filed February 20, 1914. Serial No. 819,939.
To all whom it may concern Be it known that I, LovmJrW. COOPER, a citizen of the United States of America, residing at the city of Schenectady, in the county of Schenectady. and State of New York, have invented certain new and useful Improvements in Automatic Stop-Valves, of which the following is a specification.
My invention relates to controlling valves for fuel oil' or gas, and the object of my invention is to provide a means for auto matically controlling the delivery of oil or gas to a furnace; together with such elements and combinations as are hereinafter more particularly set forth and claimed. I accomplished these objects by means of the mechanism illustrated in the accompanlying drawings, in which:
Figure, 1 is an elevation of my invention. Fig. 2 is an elevation partly in section, showing the diaphragm and means for releasing the weight: Fig. 3 is a section of the valve through which the gas or oil passes, showing the means for opening and closing the same.
Similar letters refer to similar parts throughout the several views.
The pipe, A, is'connected with the source of supply, not shown, containing oil or gas, and inserted in the opening, a, at one end of the valve casing, B. The pipes, C, C, conduct the fluid from the valve casing, B, to the burner, D, and in the pipes, (3, there is preferably placed the valve, 0!. Air or steam is conducted to the burner through the pipes, E, E, and near the burner is preferably placed the valve, e. Connecting the pipes, E, with the diaphragm casing, F, is a pipe, G. In the casing, F, the pi e, G, communicates with the chamber, and steam or air conveyed through the pipes, E, and G, comes in contact with the diaphragm, J. One end of the bell crank lever, S, is
attached between the bifurcations of the head, Y, on the valve stem, X, and the lever is fulcrumed to a bracket, K, attached to the casing, F, and is attached to a rod, T, adapted to reciprocate in the guide, R, vas shown in Fig. 2.
The valve casing, B, is provided with a gate, L, for closing one of its ports, I), and has attached to it a spring, M, whose tendency is to lift the valve gate, and which spring is attached to the bracket, N, which tends to hold elevated the gate when it is open. On the gate, L, is formed a yoke, P,
thro gh which yoke that part of the plunger, Q, that is between the collars, p, p, passes. The plunger, Q, passes through the wall of the valve casing, B, and is connected by links, U, U, to the lever, V, which is attached to the lever, Z. The two links, U, U, are separated and at each end attached by the pins, f and g, and between the links the lever, Z, passes.
The lever, Z, carries a weight, Z, near one endand is fulcrumed to a post, 2, attached to the valve casing. In order to raise the valve'gate the lever, Z, is raised by hand above the position shown by dotted lines in Fig. 3, indeed as far as the opening, 9", in the guide, R, will permit. This raises the gate, L, because the lever engages the pin, f, which carries upward the plunger, Q, and the oil or gas flows out. The lever, Z, then gradually descends until stopped by the pin or rod, T. This removes the collar, 72, from contact with the underside of the yoke, P, and leaves the gate sustained only by the spring, M, which will hold it open as long as the pressure of the fluid on each side of the gate is the same. There is now a flow of gas or oil through the valve casing, B, and the pressure on each side of the valve casing is substantially the same. The set pin, 0, is adjusted to permit of the gate bemg opened only the required degree, de pending upon the number of burners to be used. In case of a break in the oil pipe, C, between the valve casing and the burner, the pressure being reduced, the valve will immediately close. If there should be any break in the pipe, E, or pipe, G, or any diminution in pressure of; the air or steam in these pipes, the diaphragm would go down and the rod, T, will be drawn out from under the lever, Z, and the weighted lever will drop, striking by sudden blow the link pin, g, forcing down the plunger, and the collar, p, hitting the yoke will close the gate. Thus the flow of fuel, gas or oil, is automatically shut ed, in case of accident, in the mains. This also occurs in case anything happens to the supply of air or steam to the burner.
What I claim as my invention and desire to secure by Letters Patent is:
1. An automatic stop-valve comprising a valve casing; a swingm gate therein controlling one of the openings in said casin mechanical means located outside of t e valve casing for opening said gate; and mechanical means within the valve casing for holding the gate open while the pressure is substantially the same on each side of the gate, but releasing the gate and causing it to automatically close when the pressure on the outgoing side is reduced.
2. In an automatic stop valve; the combination of a valve casing; a gate adapted to close the exit of said casing; a plunger; means for connecting said gate with said plunger; means mounted externally of said valve casing for raising the plunger; means for holding said raising means when the gate is open; a diaphragm; and means operated by said diaphragm for releasing said holding means and causing the plunger to descend, engage the gate and force the same in a closed position?" i 3. A device for automatically controlling the fluid used i'or fuel, comprising a valve casing; a gate therefor; mechanical means external of the said casing for opening the gate; means just within. the valve casing for holding the gate open while the pressure is the same on each side of the gate; a steam or air pipe; and means external of the valve casing for putting in motion the means for mechanically closlng the gate when a break occurs in the air or steam pipe.
4:- A device for stopping the flow of fuel fluid when a break occurs in the main comprising a valve casing connected to the main; a gate for controlling the passage of fluid through the valve casing; mechanical means external of said valve casing for raising the gate; mechanical means within the casing for holding the gate in its raised position while the pressure on the gate is substantially the same on each side thereof; a steam. or air pipe; and means connected with the steam or air pipe for bringing in contact with the gate the mechanical means for closing the same when a brealr occurs in the steam or air pipe,
5. A device for stopping the dew of fuel memes fluid when a break occurs either in the fluid main or in the air main, comprising a valve casing in the fluid main; an air or steam main; a burner in which the air or steam is mixed with the fluid; a gate in the valve casing; a weighted lever for closing the gate; a stop for holding the lever; a spring in the casing holding the gate open while the pressure remains the same on each side thereof; a diaphragm; means for conducting to the diaphragm air or steam from the air or steam main; and means connected with said diaphragm for withdrawing said stop and permitting said weighted lever to fall, thereby closing said gate when a break occurs in the air or steam main, substantially as described; v
6. In an automatic stop-valve, the combination of a valve casing; a swinging gate controlling one of the openings in said casing; a spring attached to said gate in said casing tending to open the gate; and mechanical means located outside of the valve casing for lifting said gate substantially as in testimony whereof I have aiiixed my signature in presence of two witnesses,
