MARION W. PITNER, OF CHICAGO, ILLINOIS.
VALVE FOR HYDROCARBON LIGHTING SYSTEMS.
To all whom it may concern:
Be it known that I, MARION NV. PITNER, 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 for Hydrocarbon Lighting Systems, of which the following is a specification.
This invention relates to improvements in valves, and particularly to valves designed for use in connection with hydrocarbon lighting fixtures and systems.
One object of the invention is to provide a valve which may be employed for a variety of uses, either, for example, for connecting a hydrocarbon feed pipe leading to the lamp or lamps of the system with a main feed or supply pipe, or for connecting the hydro carbon reservoir or supply tank with an air pump, by which air under pressure may be stored in the tank for the purpose of feeding the hydrocarbon to the various lamps and fixtures of the system located upon the various floors of a building.
Another object of the invention is to provide a valve of this character in which provision is made for straining the hydrocarbon on its passage therethrough, for effectively limiting the opening movement of the valve proper therein, for etliciently coupling the hydrocarbon feed pipe to the valve casing, and for opening communication between the system and the external atmosphere for the purpose of withdrawing a portion of the circulating hydrocarbon in order that its quality may be tested or to enable the operator or attendant to determine whether or not the hydrocarbon is circulating under proper pressure.
The invention consists of a valve embodying the novel features of construction, com bination and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying drawing, forming a part of this specification, and in which Figure 1 is a central vertical longitudinal section of the valve. Fig. 2 is a vertical transverse section thereof. Fig. 3 is an elevational view of the hydrocarbon screen or strainer.
Referring to the drawing, I designates the valve casing having an inlet end 2 tapered and externally threaded for insertion into Specification of Letters Patent.

Serial No. 376,313.
the socket of a supporting bracket or wall of the reservoir tank and provided with a feed passage 3 communicating with a central vertical passage 4 and enlarged. at its outer end to form a chamber 5 into which projects a screen or strainer 6. This screen or strainer is employed to screen or strain the gasolene of its impurities on its flow from the feed pipe to the lamps, and preferably comprises a conical or cup-shaped sheet metal body open at its inner or reduced end and provided at its outer end with a folded portion 7 forming an outwardly extending shoulder to limit the insertion of the strainer and a flange to clamp a screen or strainer disk 8 of WOVQI'I wire or other material against said shoulder. in the chamber 5 and may be conveniently removed to permit repairs or cleansing of the parts. The opposite end 9 of the casing is formed with a threaded passage 10 enlarged at its outer end to form a chamber 11, and the extremity of the portion 9 is formed to provide an externally threaded coupling 12 engaged by a screw cap or packing nut 13. A bushing 14L fits within the chamber 11 and bears upon the shoulder at the inner end of the same, and said bushing and the head of the cap 13 are formed with registering openings for the passage of a stem 15 carrying at its outer end an operating knob or handle 16.
A cut-off valve 17, having an extremity of conical form performing the function of aneedle valve, controls the feed port 3 and is provided with a threaded body portion 18 arranged to engage and operate in the threaded passage 10, the threads of the passage and valve being comparatively coarse so as to permit the valve to be quickly adjusted to open or closed position. The rear end of the threaded body portion of the valve forms an abutting shoulder 19 adapted to engage the bushing 11 to limit the opening movement of said valve, by which its retractive adjustment beyond a prescribed extent is prevented. Packing 20 of asbestos or other suitable material is inclosed in the cap or nut 20 and closes the joints between the same and the casing and the bushing and the casing to prevent leakage from the easing of the gasolene.
It will be understood that the end 2 of the valve casing may be connected with the hydrocarbon supply pipe in any preferred manner, and that the hydrocarbon on its passage from the pipe to the casing will be screened of its impurities by the strainer 8, which will prevent such impurities from passing through and clogging the burners of the lamps. Upon opening the valve 17 the hydrocarbon will flow through the passage 3 into the chamber 4, and thence out through the nipple 21 to the conducting pipe 24. The opening movement of the valve 17 is limited by the abutment of its shoulder 19 against the bushing 14, by which the opening of the valve beyond a prescribed extent is prevented. If desired, the valve may be employed as a fixture for connecting an air pressure pump with the hydrocarbon reservoir of the system, in which event the end 2 of the casing will be fitted within a threaded opening within the wall of the tank and a hose or other connection from the pump will be coupled to the nipple 21, by which, upon opening the valve 17 the air from the pump will fiow through the inlet connection 2 into the tank.
WVhen the system is in operation, it will be understood that upon turning the escape valve 29 to open the port 26 a portion of the hydrocarbon may be allowed to escape through the port 28, so that its quality or condition may be conveniently tested at any time. By this operation also the system may be tested to determine whether or not the hydrocarbon is under the proper amount of pressure, as its force of discharge through the port 28 will indicate. Hence the valve forms a convenient adjunct to lighting systems of the character specified for controlling and testing operation and may also be with a valve seat and with a lateral escape port outwardly beyond said seat, a cut-ofi valve mounted upon the end of the casing opposite that in which said feed passage is formed and projecting into the chamber and controlling communication between the feed passage and the said discharge and escape passages, and a threaded needle valve working in the escape passage and controlling said seat and port.
2. A valve of the character described comprising a casing having a central chamber,
an inlet leading through one end thereof to said chamber and formed at its inner end with a valve seat, lateral discharge and escape nipples leading from diametrically opposite sides of the chamber, said escape nipple be ing internally threaded and provided at its inner end with a valve seat and adjacent thereto with a lateral escape port, a valve working in the opposite end of the casing and having a needle point to engage the valve seat of the inlet and controlling communication between the same and the respective nipples, and a threaded valve working in the escape nipple and having a needle point to engage the seat therein and control communication between the chamber and the escape port.
3. A valve of the character described comprising a casing having a central chamber, an inlet leading through one end thereof to said chamber and formed at its inner end with a valve seat, the opposite end of the casing being formed with an internally threaded passage and an enlarged chamber t the outer end of said passage providing a coupling flange and an interior shoulder, a bushing inclosed in said chamber and resting against said shoulder, a cap engaging the flange, packing in the cap closing the joint between the flange and bushing, lateral discharge and escape nipples leading from diametrically opposite sides of the chamber, said escape nipple being internally threaded and provided at its inner end with a valve seat and adjacent thereto with a lateral escape port, a threaded valve working in said threaded passage and provided at its inner end with a needle point controlling the inlet and at its outer end with a stem projecting In testimony whereof, I aflix my signature outwardly through the bushlng, packlng m presence of two wltnesses.
