FLUID-PRESSURE REGULATOR 0R GOVERNOR FOR VAPOR-LAMPS.

SPECIFICATION forming part of Letters Patent No. 759,035, dated May 3, 1904,

Original apulication filed April 30, 1903, Serial No. 15:},9'70. Divided and this application filed June 20, 1903. Serial No.162,310. (N0 model.)

To all whom (it may concern;

Be it known that I, HARPER F. SMITH, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsyl- Vania, have invented anew and useful Improvement in Fluid-Pressure Regulators or (JirOVQlllOIS for Vapor-Lamps, of which the following is a specification.

In a conteinporaneously pending application liled by me April 30, i903, Serial No. 154,970, for vapor-burners I have shown and described a novel coi'istruction of vapor-lamp and regulating device therefor, the claims therein being drawn to the construction of the lamp.

In the present application, which is a division of the above-mentioned application, I have shown, described, and claimed a novel construction of a governor wherein the parts are inclosed in a suitable casing, at the lower portion of which is located an oil or hydrocarbon chamber having a valved opening leading thereinto and an outlet therefrom whereby the l'iydrocarbon in predetermined quantities is conducted to the generating devices, the lower portion of the oilchamber being provided with a suitable drip device. Above the level of the oil or hydrocarbon :in the casing is located the vaporchamber, to which the vapor from the generating devices is conducted by means of a suitable'pipe, the vapor being withdrawn from the upper part of said chamber by means ofa suitable connection which is controlled by a vapor-valve, whose action is regulated by the pressure ofthe vapor in said vapor-chamber upon a suitable diaphragm controlled by a spring adjacent thereto whose tension can be regulated according to requirements.

To the above ends my invention consists, broadly, in the novel construction of a fluidpressure regulator which is particularly adapted for use in vapor-lamps, preferably constructed under my previous patents and pending application aforesaid, wherein the number of parts are reduced to a minimum and the construction simplified and cheapened throughout.

It further consists of other novel features of construction, all as will be hereinafter fully set forth, and pointed out in the claims.

Figure 1 represents a vertical sectional view of a fluid-pressure regulator or governor embodying my invention, certain of the parts being shown in elevation. Fig. 2 represents a vertical sectional view of my novel construction of governor, showing also a vaporlamp partly in section and partly in elevation, to which the same is applicable.

Similar numerals of reference indicate corresponding parts in the figures.

Referring-first to Fig. 1, 1 designates a reservoir and casing for the governor, which may be of annular or other contour, as will be understood from Fig. 2, and is provided with a filler 2, whose upper portion is closed by a thumb-screw 3, provided with suitable pacl ing a or other similar device. The casing 1 having been filled to the desired height it will be understood that the hydrocarbon may flow through the strainer-ports 5 and gauze 6 past the valve-seat 7, against the lower portion of which abuts the oil-valve 8, which has a stem 9 depending there from, which is surroumled by the coil or other spring 10, the upper portion of which abuts against the valve, while the lower portion of said spring is in contact with the head or closure 11, which has the port 12 therein closed by the plug 13, whereby the oil-chamber 14: can be emptied of sediment and the impurities may be removed therefrom according to requirements.

15 designates a pipe leading from, preferably, the upper portion of the oil or hydrocarbon chamber 14: to the generating device of the lamp. Above the valve 8 and in op posite direction to the stem 9 projects the sleeve 16, which I have shown in the present instance as being integral with the valve, although it will be apparent that the same can be made detached therefrom, but secured thereto with any suitable means.

17 designates a seat or recess within the sleeve 16, in which the free end 18 of the stem 19 freely slides, said stem having its lower portion threaded and provided with the lock or jam nuts 20, which can be adjusted so as to lengthen or shorten the extent of movement of the stem 19, as will be hereinafter explained.

21 designates a tube which is open at its upper portion and has its lower extremity screwed or otherwise removably secured to the ring 22, which has a passage therethrough, and whose lower portion forms a valve-seat for the valve 8.

It will be apparent that the ring 22 may be made integral with the casing 1 and the contiguous wall of the oil-chamber 1 L, or the parts can be made separate and secured together by any suitable means, according to requirements. It will further be evident that while in Fig. 1 I have shown the gauze or straining device .6 as located between the sleeve 16 and the lower portion of the tube 21, if desired the gauze may be located exterior to the lower portion of said tube without departing from the spirit of my invention, it being in either case advantageously removable with said tube for cleaning or renewal.

23 designates a coupling which is screwed or otherwise secured to the upper portion of the stem 19, said coupling having its upper portion secured to the diaphragm-stem 24, whose upper portion is provided with a flange 25, which contacts with the upper portion 26 of the diaphragm 27, the latter having a lower wall 28, through which the stem 24 freely passes, it being understood that there is a passage 29, whereby communication is had between the diaphragm-chamber 30 and the vapor-chamber 31, within which the coupling 23 is located.

32 designates a diaphragm-spring chamber in which is located the coil or other spring 33, the lower portion of which contacts with the flange 25, while its upper portion contacts with the under side of the adjustingscrew 34, which can be readily manipulated from the exterior for varying the tension of the spring 33.

35 designates an arm extending from the coupling 23, to which is pivotally attached the vapor-valve 36, the latter consisting of a rod passing upwardly through the guide 3'7, it being apparent that the upper extremity 38 of the valve opens or closes, according to requirements, the passage 39, wherefrom the yapor is led by the pipe 1O downwardly to the regenerator etl, and it being further understood that the vapor is led into the vaporchamber through the pipe 12 from the generator 13.

The operation of the governor or fluid-pressure regulator seen in Fig. 1 in communication with the lamp seen in Fig. 2 is as follows: The casing or reservoir 1 having been filled to the desired level through the filler 2 it will be seen that the hydrocarbon flows from the pipe 15 through the valve 44, where it divides,

the pipe 45 downwardly through the lower portion 46 of the generator 43, wherein the oil is vaporized, the vapor flowingout through the pipe &2, hereinbefore referred to, and exerting its pressure in the vapor-chamber 31, said vapor flowing past the vapor-valve 36 and flowing outwardly through the pipe 10 downwardly into the regenerator 41 and from thence through the nozzle e17 and commingling-tube 48 to the burners 49.

I have purposely omitted to describe in detail the precise construction of the burners 49, the starting devices, the generator and regenerator, and their adjuncts, since 1 herein make no claim to them, and the foregoing are fully described in my coutemporan'eously-pending application, Serial No. 154,970, filed April 30, 1903, of which this case is a division.

The operation of the governor is as follows: It will be understood that the oil-vahe 8 regulates the passage of the oil or hydrocarbon to the pipe 15 and that said valve is controlled by the compressionspring 10. The vaporinlet to the vapor-chamber 31 is through the pipe 12, and the outlet from the vapor-chamber is governed and controlled by the vaporvalve 36, which controls the flow of the vapor through the pipe 40. This vapor-valve 36 acts in unison with the compression-spring 33,

which abuts against the diaphragm, which causes the proper movement of the connections 2%, 23, and 19, which action either compresses the spring 10 or permits of its expansion, thereby opening and closing the oil-valve 8 and permitting the hydrocarbon to How past said valve or stopping the flow of the same therethrough. WVhile the vapor-valve 36 acts in unison with the hydrocarbon-valve 8, its oificeis entirely independent and its operation separate and distinct therefrom, for when the pressure in the governor exceeds the point at which it is set the spring above the diaphragm moves the connections 2 k, 23, and 19, thereby allowing the hydrocarbon-valve 8 to move by the expansion of the hydrocarbon-spring 10, which closes the hydrocarbonwalve 8 and shuts off the supply of fluid to the vaporizer. Now when the hydrocarbon-valve 8 refuses to respond to the action of the compression-spring 33, resting on the diaphragm below it, owing to any dirt being on the face of the valve 8, a disarrangement of the spring 10, or for any other cause, and the pressure continues beyond the point set, then the box-diaphragm will still further expand and cause the vapor-valve stem 36 to become seated, which immediately cuts off thesupply of vapor to the pipe 40, thereby extinguishing the light, when vaporization ceases in the generator and the pressure is at once destroyed, owing to the stoppage of the vapor to feed the burner.

It will be apparent that while I have shown in Fig. 1 the preferred construction of my governor or fluid-pressure regulator and have indicated the diaphragm, vapor-valve, and its adjuncts as being in the upper portion of the apparatus, and the oil-chamber, oil-valve, and oil-spring as being in the lower portion thereof, I do not desire to be limited thereto in every instance, for it is apparent that changes may be made in the manner of constructing and assembling these parts by those skilled in the art which will come within my invention, and I reserve to myself the right to make all such changes as fall within the scope of the same.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is
