AUTOMATIC VALVE FOR WATER-HEATERS.
SPECIFICATION forming part of Letters Patent No. 733,861, dated J uly 14, 1903.
Application filed April 1,
T0 to whom it may concern:
Be it known that we, GEORGE A. MENTEL and JOHN B. PAUL, citizens of the United States of-America, residing at'Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Automatic Valves for Water-Heaters, of which the following is a specification, reference being bad therein to the accompanying drawings.
This invention relates to certain new and useful improvements in automatic valves for Water-heaters, and has for its object the provision of novel means where the gas-supply is regulated by the temperature of the water.
Another object of the present invention is to provide novel means whereby said valve may be regulated to shut oi the gas-supply when the water reaches a certain degree of temperature.
Another object of the present invention'is to provide a device of the above-described character that will be extremely simple in its construction, sensitive to the various degrees of temperature, strong, durable, comparatively inexpensive to mannfacture,and highly efticient in its operation- With the above and other objects in view the invention consists in the novel construction, combination, and arrangement of parts to be hereinafter more fully described, and specifically pointed out in the claims.
In describing the invention in detail refereuce is had to the accompanying drawings, forming a part of this specification, and wherein like numerals of reference indicate like parts throughout the several views, in which- Figure 1 is a vertical sectional view of our improved valve. Fig. 2 is a side elevation thereof, showing the same operatively con nected to a boiler.
In the drawings the reference-numeral 1 represents the hot-water reservoir, having a cold-water-inlet pipe 2, which pipe extends centrally into the reservoir and is provided wit-h an enlarged beveled end 3, into which extends the pipe 4, closed at its upper end and terminating at its lower end in casting 8, formed integral with the casing 9, which is formed in two sections, the lower section be- 1902. SerialNalOLOlB. (Nomodeln ing designated by thenumeral 9. The lower portion of the hot-water reservoir is provided with an internally-screw-threaded neck or down wardly-extending portion 13. Connect ing with this neck 13 is a branch pipe 5, leading to the coil 6 and terminating inthe hot water pipe which extends into the reservoir 1. The sections 9 and 9 carry corresponding screw-threads't)", and a diaphragm 10 is interposed between the sect-ions 9 and 9*.
Within the pipe 4 and upper section of the casing 9 above the diaphragm is held a quan: tity of mercury or other expansible fluid. The section 9 is provided at its lower end with an externally-screw-th readed portion 11, which is threaded into the casing 12, forming a chamber 14, this casing 12 being contracted, as shown at 15, and has secured therein a stuffing-box 16. This casing 12 has formed integral therewith acasing 17, provided with an inlet 18 and a gas-outlet 19. The gas-inlet 18 comm u nicat-es with the gas-supply pipe, and the gas-outlet is connected to a supplypipe 20, to which is secured the burner 21, which is directly under the coil 6. Under the diaphragm 10 in the section 9 of the easing is secured a head 22, connected to the rod 23, the latter extending into the casing 12. A spiral spring 24 encircles the rod at its up per end and rests against the under face of the head 22, and the lower end of the spring is seated against the casing .9 The said rod 23 is formed in two sections, the lower section being designated by the numeral 25. The sections of the rod are secured together by means of a turnbuckle'26, arranged in the casing 12. The lower end of the section 25 of the rod carries avalve 27, which is adapted to operate in the valve-seat- 28, formed in the casing 17, and regulates the gas admitted from the supply-pipe into the casing 17, which supplies the pipe 20 and burner 21." The reference-numeral 29 represents the pilot-light phragm 10, forcing the valve downwardly, thereby closing the entire supply of gas and causing but a small flame to burn in the pilotlight 29. The reverse movement 'of the diaphragm will be obtained in case the water is cold, the mercury will contract, allowing'the expansion of the spring 24:, thereby raising the valve and permitting a larger flame to burn under the coil 6, therebyheating the water in the boiler.
The many advantages obtained by the use of our improved device will be readily apparent from the foregoing description, taken in connection with the accompanying drawings.
It will be noted that various changes may be made in the details of construction without departing from the general spirit of our invention.
Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is
1. In a device of the character described, the combination of a hot-water reservoir, a
supply-pipe terminating therein, the lower end of said pipe being enlarged, a coil communicating with the said reservoir, a casing, a diaphragm arranged within the said casing, a pipe secured to the said casing, said pipe extending into the enlarged lower end of the said supply-pipe and being closed at its up per end, a gas-supply pipe, a pilot, a burner, means actuated by the said diaphragm for automatically controlling the supply to the said burner, substantially as described.
2. In a device of the type set forth, the combination of a hot-water reservoir, provided with a depending neck, a casing secured to the said depending neck of the reservoir, a diaphragm arranged in the said casing, a pipe in communication with the said casing and extending upwardly into the reservoir, means for heating the water in the said reservoir, and means actuated by the said diaphragm for controlling the said heating means, substantially as described.
3. The combination with the reservoir, of a casing secured to the said reservoir, a diaphragm extending across the interior of the said casing, said casing being adapted to receive on one side of the said diaphragm mercury or the like, a pipe in communication with the casing, said pipe extending into the said reservoir and having its one end closed, a heating means for the said reservoir, one end of said means terminating adjacent the said pipe, and means actuated by the said diaphragm for controlling the said heating means.
4. The combination With the reservoir, and the supply-pipe arranged therein, said reservoir being provided with an integral tubular extended portion, a casing secured to the said extended portion of the reservoir,a pipecarried by the said casing and extending upwardly into the said supply-pipe, a diaphragm arranged in the said casing, said diaphragm dividing the said casing into two compartments, said pipe and adjacent section of the casing being adapted to receive a liquid effected by atmospheric changes, a water-coil communicating and exterior with the said reservoir, one end of said coil terminating in said extended portion and adjacent the said pipe carried by the said casing, a heating means, agas-supply pipe communicating with the said-heating means, and means actuated by the said diaphragm for controlling the supply of gas, substantially as described.
In testimony whereof we affix our signatures in the presence of two witnesses.
