VALVE.
Specification of Letters Patent.
Patented oct. so, 190e. Y
Application led August 25, 1905. Serial No. 275.798.
To all whom it may concern,.-
Be it known that I, HENRY C. MONTGOM- ERY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Valves, of which the following is a speciiication.
This invention is a slow self-closing valve adapted to be used in places where it is desired that a certain quantity of liquid shall flow and then be stopped. lIt is particularly serviceable and intended for use in flushing Water-closets by directy flow from the watermain.
The object of the invention is to form an improved valve of the kind which after being opened will close slowly and silently, the rate of closure being controlled by the difference in area between two heads of the valve which are subjected to the water-pres-` sure.
In the accompanying drawings, Figure 1 is a central vertical section of the valve. Fig. 2 is a central vertical section of the cylinders in which the valve-piston and push-rod work.
Referring specifically to the drawings, 6 indicates a globular, valve-casing having a water-inlet 7 at the bottom and an outlet 8 at the side. Extending across this casing is a diaphragm 9, in which is screwed a cylinder 10, which is closed at the bottom, as at 11, and has two chambers of different sizes, the
upper chamber, which is the larger, being indicated at 12, and the lower chamber at 13. O ening into the upper chamber are a series ofp lateral ports 14, which are extended upwardly, as at 15, to form a passage of large capacity. These -ports open below the diaphragm 9.
' Within the cylinder 10 is a piston-valve 16, having at the top a head 17 and at the bottom a head 18. The area of the head 17 is greater than thatof the head 18, and the ter is lifted. The cylinder 23 has a threaded bears at its-lower end u on the top of the Y ycylinder 10. This cylin er 23 has ports 25 to allow the'outflow of the water into the space above the diaphragm, and thus to the outlet.
The cap of the casing is indicatedl at 26, screwed into the top thereof. The push-rod 27 for opening thevalve works through this cap and has a piston 28, which fits in the cylinder 23 and on its upper end has a handle 29 for its operation.
In the o eration of the valve the upward pressure o' thewater thereon normally lifts it and holds it closed. To open it, the handle is pushed down, forcing the piston to the bottom of the cylinder 10. The water then flows in and upthrough the ports 14 and 15 and out through the ports 25 to the outlet.k The water gets under the head 17 and gradually under the head 18, and the piston thus lifts slowly until it is closed, after which it is held closed by the water-pressure until the next operation. As the water ilows up through the valve-opening it lifts the piston 28 and the valve-rod out of the way of the valve-piston. The by-passage 30 vthrough the wall of the cylinder 23 allows the escape of any leakage through the piston 28 and avoids necessity for packing between the rod 27 and the cap 26 or on the piston 28.
What I claim as new, and desire to secure by Letters Patent, is-
I 1. A valve comprising a casing, a cylinder supported therein, and having inlet and outlet openings, a piston movable in the cylinder and constructed to close the outlet by pressure of the fluid, an upper cylinder supported in the casing, and a push-rod whichl extends through the casing and has a piston in said upper cylinder which receives the pressure of the iiuid when the valve is opened, and is arranged to bear at its end against the piston, to open the valve, when the rod is pushed down.
2. A self-closing valve comprising a cylinder having an inlet and an outlet, a iston movable therein, and arranged to adffance and close the outlet by the fluid-pressure, and having means to delay its advance, another cylinder beyond said outlet and in line with lthe first-mentioned cylinder, and a pushrod movable against the piston, to push the same back, and having a piston insaid other IOO IIO
cylinder arranged to receive the pressure of the fluid passing the outlet, to push the rod back from the piston.
3. A valve comprising a casing, a lower cylinder therein closed at its lower end and -having an outlet-opening at its upper end and an inlet at the side, a valve piston itting loosely in the cylinder, an upper cylinder screwed into the casing against the top ofthe lower cylinder and having an overhanging edge at the said outlet-opening against which the piston seats, and also having outlet-ports7 and a push-rod extending through the casing and having a piston in the upper cylinder,
and arranged to push against the valve-pis- 15 narne to this speciication in the presence of 2o two subscribing witnesses.
