SPECIFICATION forming part of LettersPatent No. 465,898, dated December 29, 1891. Application filed March 30, 1891. Serial No. 387,017. (No model.)
.Z aZZ whom, it may concern.-
a citizen of Allegheny, in the county of Allegheny'and State of Pennsylvania, have invented certain new and useful Improvements in Valves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
Myinvention relates to an improvement in valves, and more particularly to such as are employed to regulate the vacuum in receptacles from which a portion of their contents 1 5 have been withdrawn. 1
In some instances (as in saloons) liquids are withdrawn from the casks or barrels containing them by means of pumps actuated by Water'motors, and the vacuum in the cask or 2'0 barrel becomes so great as to require motors of larger size than are really necessary, and the water-pressure which operates the motor inmany places (such as large cities) varies, thus rendering the pumps, or rather the pump- 2 5 motors, insufficient for proper service.
It is the object of my present invention to overcome these objections and to produce a valve connected to the vessel so that the amount of power required to drive the pump 0 can at all times and places be kept within the range of the motor.
With this object in view the invention consists in the combination, with a cask or faucet, of avalve connected therewith, said valve be- 3 5 ing constructed and arranged to be actuated by the vacuum produced in the vessel and adapted to admit air when said vacuum becomes too great.
The invention also consists in the combina- 0 tion, with a vessel or faucet, of a valve attached thereto, said valve comprising a yielding disk, an opening in said disk adapted to be closed by a movable block or valve-seat, a spring to maintain the valve normally closed,
and an air-inlet port; and the invention also consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.
larged vertical sectional view of the device.
Fig. 3 is a view of a modification.
A represents a vessel adapted to contain liquid to be drawn out by means of a pump. Connected with the vessel A is my improved valve B. The casing of the valve is madein two parts 1 2, the part 1 being provided with a perforation 3 for the reception of the stem 4 of an elastic disk-valve 5, and by means of this perforation 3 communication is established between the valve and the interior of the vessel. The valve or disk 5 is preferably made of circular piece of sheet-rubber and is securely held in place between the parts 1 and 2 of the casing, which latter are secured together bysuitable fastening devices 6. The
valve-stem 4 is passed through the center of the disk 5 and is made to project above and below the same, said valve-stem being made tubular and secured to the disk by means of plates or washers 7 on opposite faces of said disk. The perforation 3 is enlarged somewhatthroughout a portion of its length for the reception of a coiled spring 8, adapted to bear on the under one of the washers 7 and force the valve-stem upwardly normally in contact with a movable block or valve-seat 9, carried by the section 2 of the casing, the inner faces of both sections 1 2 of the casing being recessed to permit theproper vibration of the valve. The movable block or valveseat 9 is prevented from escape by means of a cover 10, placed on top of the section 2 of the casin An air-inlet port 11is madein the section 2 of the casing and is adapted to communicate with a similar inlet in the cover 10.
The device,being thus constructed, operates as follows: WVhen the partial vacuum in the vessel becomes great enough to overcome the spring 8, which determines the vacuum in the vessel, the valve is drawn down and its hollow stem made to move away from its movable seat 9, which latter, it will be seen, is selfadjusting. When the seat comes in contact with the rim 13 of the-chamber in which it is confined, air passes through the port 11 into the casing, and thence through the hollow valve-stem to the vessel, reducing the vacuum in the vessel.
In Fig. 3 myimprovement is shown applied to a faucet instead of a barrel.
Slight changes might be made in the details of construction of my invention Without departing from the spirit thereof or limiting its scope. Hence I do not wish to limit myself to the precise details of construction herein set forth; but,
Having fully described my invention, What I claim as new, and desire to secure by Letters Patent, is
1. In a valve, the combination, with a casing, of a flexible disk, a hollow valve-stem carried byand passing through said disk, and a movable valve-seat for said stem, substantially as set forth.
2. In a valve, the combination, with a casing, of a flexible disk carried therein, a hollow valve-stem carried by and passing through said casing, a spring under said disk, and a movable valve-seat for said valve-stem, substantially as set forth.
3. In a valve, the combination, with a casing, of a flexible disk, a hollow valve-stem carried by and passing through said disk, a spring under said disk, a movable valve-seat for said stem, and an air-inlet communicating with the casing above the flexible disk, substantially as set forth.
4. The combination, with a vessel, of a valve attached thereto, said valve comprising a yielding disk, an opening in said disk adapted to be closed by a movable block or valve-seat, a spring to maintain the valve normally closed, and an air-inlet port, substantially as set forth.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
