Application filed August 29, 1914; Serial No, 859 199:
Be it known that I, FRANK C. Roux, a. citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented a new and useful Regulator-'Valve fOPGaS-BUI'IIGIS, of which the following is a specification.
My invention relates to improvements in regulator valves for gas burners in which the supply of" gas is regulated by the pressure'of steam and is more especially adapted to be used in" connection with a gas burner for heating steam radiators and the like.
The object of this invention is to provide a regulator valve by means of which the supply of gas is regulated by a pressure of steam.
Another objectis to provide means" for automatically controlling the supply of fuel to the steam producing burner.
Another object is to provide adjustments by which the supply of fuel may be regulated with different pressures of steam.
\Vith these objects in view the invention consists in the novel construction and 511'", rangement. of parts, hereinafter described, illustrated in the" accompanying 1 drawings, and particularly pointed out in the appended claim, it being understood" that various changes in the form, proportions, size and minor details of construction may be made without departing from the spirit or sacrificing. any of the advantages of: the invention.
In the drawing: Figure 1 is a: fragmentarvsectional view of: a. portion of a steam radiator and gas burner showing my improved regulator valve in connection therewith. Fig. 2 is a sectional view of the regulator valve. Fig. 3*is' an enlarged sectional View of the'needle valve whichautomatically controls the pressure of gas. Fig. 41' is a similar view of the split needle valve which controls the flow of'gas to the burner. Fig. 5 is a section on line 5-5, Fig. 3. Fig. 6 is a section online 6-6, Fig. 1
Similar numerals of' referencerindicat'e corresponding parts throughout the several views in-the drawing; I
In the accompanying drawing, 1 represents the lower portion of the end section of a. steam radiator and 2 represents the adjoining sections which are connected in any suitable and well known manner as by the rings 3 which. allow communication"between all of." thesectionsas shown. A t'himble 4:
is screw threaded into the section 1 and a small section of pipe 5' which isconnected to the regulator valve is slidably' mounted within said thimble, extending into the interior of the-radiator at a point above the water line, asshownin Fig. 1 of'the drawing. The pipeo is connected by an elbow 6 and a shortpip'e 7 which'is screw threaded into the neck 8 of the top 9 of the steam chamber casing. The body portion 10 of the steam chamber casing is provided with screw threads around'itsperiphery by means of which an internally screw threaded cap ll isconnectedthereto. said cap, being provided with an inwardly disposed annular flange 12 which contacts with the shoulder 13 ofthe top 9, clamping said top upon the body portion 10 of the casing. A flexible diaphragm 14 preferably composed of thin sheet metal is provided with the off set flange 15 which is adapted to rest between the shoulder'16 of the steamchamber casing 10 and the cap 9, a gasket 17 being preferably interposed between said flange" 15 and the'cap' for the purpose of making a steam tight joint. 7 V
--A screw threaded nipple I8 is provided upon the lower extremity of the casing 10, to which is attached the portion 19 of the valve casing. To the portion 19 of the valve casing is attached a supply pipe 20 by means of a union or elbow'21 as shown, saidelbow being connected" to the casing by means of the screw threadsQQ. The" supply pipe is connected to any suitable source of supply" such as" street pipes properly connected to a gasometer or' other source of supply, reference being had to the kind of gasemploye'd. A cut-off valve 23 is located inthe' casing-19-andfis'adapted to be operated by means of a handle 24:, said valve being for the purpose of shutting ofl" the supply of gasto the valve when desired.
A spring chamber 25"is provided in the casing and a concentric cylindrical bore 26 communicates therewith. A needle valve 27 is'located through thecylindrical bore 26 and is'providedupon its upper extremity with a thimble 28 which bears against the diaphragm 14. The thimble has an annular flange 29 around its upper edge and a spring 30 is interposed between said flange and the lower-wall 31 of the spring chamber. The lower extremity ofthe needle-273s tapered. at 32" and provided w'ith a reduced point 33, .the' tapered end 82" being" located within the conical valveiseat 34 and the point 33 in the reduced aperture 35. which communicates with the chamber 36 which Ywill hereinafter be described. A chamber 37 communicates with the gas supply line '20 through the channel 38 when the shut-* offvalve 23 is open.
The valve 27 is provided with transverse grooves 39 preferably located at right angl'es'as shown in Fig. 5' and extending long tudinally through the needle to a point within the nipple 18. An inlet port 40 is located in the. needle 27 and forms a communication between the chamber 37 and the central channe-l14l of the needle.
A regulating needle valve 42 provided with a screw threaded portion 43 is located through the chamber 36, the screw threaded portion 43 being engaged bv the internal screw threads 44 and a. stufling box 45 being located around said screw threaded portion for the purpose of forming an air tight joint. The needle 42'isconstructed similar to the needle 27' having a pair of transverse slots 46 extending longitudinally therethrough to a point within the chamber 36,
an inlet 47 forming communication between the chamber 36 and the central channel 48 of the needle. The needle 42 is tapered at 49 and provided with the reduced point 50, said tapered portion being located within the valve seat 51.1the reduced point 50 being situated within'the aperture 52, the opposite end of the needle valve being provided with a squared head 53 by means of which the 'needle may be rotated for the purpose of regulating the flow of gas therethrough. This needle valve 42 I do not clalm as my invention in this application.
An ordinary mixer54is connected'upon the neck 55 in any suitable andwell known mannerand provided with ,the usual apertures 5Gto allow the-admission of 'air. A
tube-f 57 is connected with the mixer and passes through the aperture 58 in the lower chamber 59 ofan ordinary .Bujnsen burner 60. The tube 57. is slidablv mounted within the aperture 58 and is held in position by means of a set screw 61, and the inner open extremity of the tube is covered with a wire gauze 62 for the purpose of preventing the flame from passing back into the valve in theevent that the gas pressure becomes low.
The burner is supported within a sheet metal housing 63 which may beattached to the lower portion of the radiator sections in any suitable and well known manner andis adapted to retain the heat of theburner 60.
Theoperation of the device is as follows: Then the steam pressure, becomes lower than desired. thereby reducing the radiation,
,the'spring 30 will cause the needle 27 to move upwardly causing the tapered ekvtremity 32 of the needle to be moved out of ;the conicalseat 34 thus allowlng the split pressure.
conical seat 34, therebv reducing 'the central channel 41 in the needle and thus reducing the supplyof gas to the burner. It will be notedthat by this construction of split needle valve, the supply of gasto the burner will never be entirely-cut-otl automatically,
the channel 41 always allowing enough gas to pass into the burner tockeep the burner lighted.' In the ordinary form of needle valve sufficient pressure upon the-needle would entirely close'the valve and cut off the entire supply of gas to the burner,thus' extinguishing the light in the burner. As the steam pressure is reduced and'the needle valve opened a supply ofgas would again .be admitted to the burner and the gas would continue to escape, thus "often lo ceasioning accident. 7 p c It is wellunderstood that in heating systems, the degree of heat desired varies from j time to time, owing to different degrees of temperature and during. excessive cold weather more heat is required than is ne cessary during periods of moderate temperature. In order to provide 'for the'proper I00 regulation of the heat with reference .to weather' ccnditions'the adjustable thimble 28 is provided, which: thimble is located upon the needle 27, and is provided with the for one end of the spring .30, the opposite end .of. said ,spring abutting against the inner end of the valvecasing 31. V J
It Wlll be understood that by adjusting 1 flange 39, which flangeforms an abutment the thimble in opposite directions, the .'ten'-- sion of the spring will be increased or decreased. reference being had to the adjustrnent of the thimble, bvwhich adjustment greater or less steam. force isrequiredso that'the degree of heat-may be Yautomati cally regulated vto produce, the desired amount of heat, referencefbeing had to' weather conditions as to heat and'cold.
The tube 57. is adjustably mounted withe in the aperture'58 oflthe. burner in order to increase or decrease the pressure-of gas-to the burner by reason of, thesiphoning efi'ect. WVhen the tube 57 ismoved farther into the burner the gas will be brought'closer to. the.
pressure. As the tube is withdrawn the gas is injected into the burner fartherfrom the .pointof combustion, thus decreasing the This tube 571 do not claim as my invention. V V 1 V Although the drawings and'above speeifi point of combustion, thereby increasingthe cation disclose the best mode in which I have contemplated embodving my invention I desire to 'be not limited to the details of such disclosure, for, in the further practical application of my invention, many changes in form and construction may be made, as circumstances require or experience suggests, without departing from the spirit of the invention, within the scope of the appended claim.
In combination with a valve casing provided with a conical valve seat and an internal shoulder, a flexible diaphragm located within said casing, a needle slidably mounted within said casing and provided with a tapered extremity adapted to fitsaid conical valve seat, said tapered portion of the needle being split longitudinally in planes at right angles to each other and provided with a central longitudinal channel connected therewith, a thimble provided with longitudinal slots and adapted to frictionally engage the other extremity of said needle in any desired adjustment, the upper extremity of said thimble contacting with said flexible diaphragm, an annular flange provided upon said thimble and a coil spring located between said flange and the internal shoulder in said casing.
In testimony that I claim the above, I have hereunto subscribed my name in the presence of two witnesses.
