Application led April`2l, 1920. Serial No. 375,440.4

To all w/om t may concern f Be it known that I, GEORGE N. BLANGrIaRD, a citizen .of the United States, residing at the city and county ofSan Francisco and State of California, have ,invented certain new-and useful Improvements in A Burner roi. which the `follovmig 1s a` Attachments, sp'ccilication.

The present invention I, relates." to an` ap paratus for heating'and igniting a'suitabc hydrocarbon fuelgenerator; one Wlilch 1s automaticallyon'trolled by a predetermlned' whereby gas for 'heating and igniting the generator is generated for a i' vgiven periodjand is automatically ignited,-

and isthen extinguishedat the termination of this predetermined period.

The' prlncipal object of the present in-i ventionV is to provide an apparatus of the' above type, `whereby the operator after startleave it unattended with the assurance that a sufficient quantity of gas Will begeeratcd and automatically ig-f.

nited toraise the temperature of the main fuel generator to a givempoint and thence i nite the gas issuing therefrom,and after teseoperations will automatically shut oil Without any danger of floodinglor operating fprmore than the predetermined or required time. A

Witl1 'the above mentioned and other objects in view, the invention consists'in the novel construction and combination of parte hereinafter described, illustrated in the accompanying drawings, and pointed outin appended; it being understood .that various changes in the form, proportion', size and minor details of construction Within the sc ope of the claims may be resorted to Without departing from the spirit 0r sacrificing any of the advantages of the invention.

To more fully comprehend the invention,

dra-wings, wherein- 'j Figure l is a'longitudinal -sectional view of one form of :burner illust-rating my improved apparatus positioned in operative rereference is directed to the accompanying tion of the arrows.l

rear open end of Fig. 2 is a vertical sectional view takengrig, i is a view in Sideeievauon 'of my .improved apparatus, partly `in section, the

characters of reference designate correvspending parts-l indicates any conven- 5, illustratingthe chan- 'y tlonal form of hydrocarbon burner-formed with a 1suitable air inlet burner opening 3.' I

Disposed above the burner 1 andv extend` .ing parallel with the pilot` burner opening 1s a suitable generator, 4, within which is generated any vsuitable hydrocarbon fuel gas which discharges from t "e tip end 5 thereof into the main burner 1.

Hydrocarbon fuel is fed to the generator through the valve controlled feed pipe 6, connected to any suitable source of uelsupply, and the gas discharging from the tip 5 is adapted to be controlled 2 and the pilot' in the generator 4;

Disposed parallel with the generator 4, slightlyvbelonhand at one side thereof and of a length corresponding to that ofthe eoV by a suitable needle valve 7 disposed longitudinally Withgenerator 4, is a suitable tubular member or torchS provided in its surface, adjacent 'said generator 4, with a line of ricci-ations 9, those at the terminal end of t e torch being preferably larger than those adjacent the base of the torch. 'The -torch is supf portcdat its rear-endby the plate l0, through which it passes.` and which is se-- cured to an arm 1l extending upwardly from the rear. of the buifner l.y Threaded into the rear open end the torch 8 is a suitable chambered member trally of the rear end othe toro-h "5 and a lateral opening le connected With one end of-a suitable' generating pipe l5. The thefchainbered member 12 is closed by a suitable .plug 16 threaded thereinto', Fig. fi of the drawings. j

vMounted at one side of the rear end of the torch and supported bythe plate 10 is'asuitable cylindrical'shellrlf( open at yits 4top and bottom, and over thejop, in`

12' provided 'with a discharge openingfl disposed censpaced relation to the upper open end thereof, is held a Suitable cover 18. Beneath the shell 17 is held i; suitable circular burner 19 ot any wick material, such as fabric or asbestos, and the fuel is supplied t0 this burner through a feed pipe 20, at the outer end of which is secureda suitable receptacle 1 having an open top 22 and which is adapted to receive a quantity of fuel, preferablv wood alcohol.

`Xtending transversely through the upper end of the shell 17 and secured at its l inner end to the plate liy the nut 23 is a within the saine is'received a flexible closurev plate 28 which confines the fluid 25 within the tubular portion 24. rlhe plate is held in position by a collar 29 threaded into the enlarged rear end '27 of the tube 24, and'said collar is in turn closed by a suitable body 30, threaded thereinto and provided with an opening 31 extending therethrough in line with the chamber of the tube 24.

Mounted within the recess 32. formed by the collar 29 and body 30, is a suitable piston 33, the head 34 being held in contact with the plate or diaphragm 28 by a coiled spring 35 positioned between theiinderside of the head 34 and the wall of the body 30 'surrounding one end ofthe opening;r 31.

The outer end of the body 30 in line with the opening 31 therethrough is chainbered, said chamber being closed by a' plug `36, chambered as at 37, and in said chamber 37 is adapted to reciprocate atapered valve 33 having adjustable connection with the stem 33 of the piston. The valve 38 is adapted for controlling;` the communication between the interior of the channel 31 and the cham ber 37, and the adjustment of the valve relatively to the piston controls theoperation of the valve in accordance with different temperatures of thefluid 25. The body 30 is provided with a lateral fuel feed' opening 39 communicating at one end with the channel land with which is connected a pipe 40 leading from a T 41 in the fuel feed pipe 6, thus fuel is fed through the pipe 40 into the channel 31. 26 of the generator pipe 15 communicates with the chamber 37 through intersecting channels 41,'and thus the flow of fuel from the pipe 40 into the pipe 26 is controlled by the operation of the valve 38 which is actuated in accordance with the temperature of the fluid 25 in the tube 24, which is in The terminal portion turn controlled by the flame from the burner 19. To ignite the generated gas `passingfrom the perforations 9 in he torch 8, 1 provide a co. ducting tube 42 open at its opposite ends, and at its innei` end commuuicat- 7o ing with the interior of the shell l' above the burner 19 throufrh an opening 43 in the Sie@ wii of, the Shell. This @mi i ai@ mit 42 is beveled, as in Fig. 3 of *he drawings, and a suitable guide or directing plate 44 secured to the shell 17 at one side or' the openinfr 43, extends into thisl beveled end of the tu e 42, as in Fig. 3 of the drawin s. The outer endof the tube 42 is open for its full areavard terminates slightly in rear of the innermost perforation 9. ,A

Extending radially from the torch 8 iinrnediately in advance of the outer end of the tube 42 is a gas conducting and torch igniting tip 45, the lower end of-which extends a short distance into the torch 8, as at 46, and is provided with a lateral opening 47 facing; the discharge opening 18 in the plug 12. The upper end of the member 45 is closed by a plug 48 and is proiided in its opposite side walls with registering openings 49 and 50, the opening 49 facing the perforations 9 and the opening 50 facing the discharge of the tube 42.

The device being assembled as in the drawings, the saine operates in the` following mannere- The chamber or container 21 being filled with a quantity of fuel known to burn through the wick a predetermined period 100 and the valve of pipe 6 being opened and 7 closed, the wick 19 is ignited. The flame from the wick 19 completely fills the shell 17, heating the liquid in the tube 24, and at the same time heating the pipe 15 coiled 105 about the tube and within the shell 17. On the raising of the li uid 25 to a predetermined teznperature dependent on kthe adjustment of the valve 38 on the stem 33, the valve 38 is opened, permitting fuel to pass iio from the pipe 40 into theportion 26 of the pipe 15, which conductsthe fuel into the coils within the shell 17. These coils being rat a high temperature, the fuel in passing therethrough is readily gasified and dis- |15 charges therefrom through the nozzle `13 1 into the torch 8. The flame from the burner 19, due to the draft Within the shell 17 and the relative position and formation of the plate 44 and beveled end of the tube 42, ig- 120 nites the gas, which is directed rearwardly through the tube 42 from the opening 50. The gas under pressure as delivered into the torch 8 through the opening 13 is directed toward the opening 47 and the open lower 125 end 46 of the igniting tube' 45, andin passing upwardly through said tube 45 discharges through both openings 49 and 50. However, only the opening 50 is necessary, and the opening 49 may be dispensed with. 13o

The gas discharged.'fromfthe opening rearwardly into the tube 42 is directed thro the opening 43 in the shell 17 and is thus ignited bythe flame Within 'the shell, causing what may be termed a .back-tire in the tube 42, which, in turn, ignites-the gas :discharging from the perlorations in the torch 8. .l op t will thus be apparentthat all opera;

tions, after the'igniting of the Wick 19, are' automatic in ger'ierating the fuel for the torch and lin igniting the torch. .On thefuel 2l being consumed by the ila-me of the Wick 19, the tube 24 .becomes cooled, permitting the -valve 38 to Seat and shut od lthe flow' 'of fuelV passing'into the chamber 36. At such time as the'torch l'hasbecome suiflcientlyI heated, the valve may be Iopened and the flame from the perforations of the terminal end .of the torch `will ignite the gas passing from4 the burner tip 5 of the. generator `Iclaim:. j 1.- An apparatus y for the 'described p`ur- Apose, the same `comprisingan elongated tu:
