To all whom t may concern:

Be it known that I, FRANCIS A. JoHNsoiv,

a citizen ofthe United States, residing at.

Kansas City, inthe *county of Jackson and State of lilissouri, haveinvented new and useful Improvements in Automatic Regulators for Gasolene-Burners, ot which the following is aspecifi'cation.

This invention relatesto automatic regulators for gasolene burners, the object yin view being to provide a regulator of the class' described which is particularly de signed for heating or blow torches.l f

The invention is Vparticularly designed for welding steel rails, 'the frames of locomotives, and for heating. the" .tires of' locomotives in order to` facilitate puttingthem on'l y and removing the samef-'from'the wheel.

Al further objectif of the invention is .to provide a device of the class described which `will embody a maximum degree of safety,

and in which the pressure will automatically maintained at a predetermined point,

so thatthe4 air and gasolene will be properly proportioned and thoroughly mixed,

v1'c pa'1"atory to ignition.

f ,With the above and other objects in view, the invention consists in the construction,-

combination and. `arrangement of parts, as will be hereinafterv more fully described, illustrated in the accompanying drawings, and pointed out in the claims hereunto appended.' I Y In the drawings: Figure 1 is a side elevation ofthe regulator embodying the present invention. F ig. 2 is a longitudinal section through the same. Fig. 3 is a section on the line 3 3 of Fig.` 2. Fig. 4 is a longi- -tudinal section through the pressurek regulator. Y

The regulating device contemplated in this invention comprises a hollow body 1, and a neck 2 forming a partof the body, and extending substantially at right angles' to the main part of thebody, as shown in Figs. 1 and 2.- At onelend, the body is internally threaded, as at. 3, to enablea pipe from an air' compressor to berscre'wed into the body,

while, at the opposite end the body is int ernally threaded, as at et, to receive a gas pipe or hose 4', by means of which the gasolene vapor may be carried any suitable distance to the point of ignition.

The air is received 1n an air inlet chamberv 5, and the assage of air through the bodyj; is controllo by an air valve 6 operating -1n .conjunction with a valve seatjv'., the valve embodying a vstein 8 which extends outward which .isinternally threaded, as shown, to

trally and longitudinally of the body, and leaves a surrounding gasolene" chamber 12,

blast ofafir passing through the n zzle `11, and atomized as it enters the service pipe or hose. f

The neck Q-comprises a gasolene passage 13 which opens out at the lower end of said neck, the latter being ta ered and threaded, asgshowii at 14, to ena le the device as a whole to be screwed into a gasolene pressure tank 15.

vided at its lower end with a strainer cage tank 1 5, and held in place by the tube 16. This tube is threaded atits upper end, as shownv at 18, in Fig. 2, while a ball check valve 19 rests lagainst the up perextremity of the tube 16, where a seat 20 is'formed :for -said ball check valve. This check valve `is employed to p prevent back nring into the gasolene tank 15. Above the tube 16 yand check valve 19, the gasolene passage 13 is deflected laterally to one side, as shown in Fig. 3 by the numeral Q1, and the wall 2:2 separating the space Q1 from the gasolenc chamber lf2 is provided with a conical opeuing forming ka vulve seat Q3, in conjunction with which a gasolene needle valve lloperates for regulating thel iiow ol gasblene into the chamber 1Q. The needle valve 'is provided with a stem 25 etending outwardly through a stuffing box, and provided with an operating wheel at its outer en d. The air and gasolene valves above described enable the quantity of air and gasolene to be properly proportioned and regulated.-

3l designates a. p

l' opening in the top of the body l.

. Communicating with the. air duct 27, at a point intermediate the ends thereof, is an air pressure regulator, comprising a body or valve casing 32, .the inner end of which is f threaded, as shown at 33, and screwed into an internally threaded opening 34 nl 'the neck 2. Inits inner` end, the body 32. is recessed, as 'at 35, to receive a valve'holder or bushing 36, in which'is arranged a sliding cone-shaped valve 37 pressed toward its seat bymeansof a coiled spring 38 surrounding the Stem 39 of the valve..- The body 32 is also chambered out to form 'a cavity 40`,-in which is laced .a valve seat 4l,

(against which the vave 37 is adapted to seat; The outer side of said yalve seat is recessed to form an airpressure chamber which is closed by .means a diaphragm 43 held between the valve seat 'dit and an internel annular shoulder 44 in said body,

The body 3 is also bored out. as shown at.

d5, toreceive a threaded turn plug d@ having central bore d'7, in which is received the stein e3 ci: a lunffer head 49 which isv pressed .towardthe diaphragm d3 by means of a coiled spring 5() encircling the stern .48 and interposed between head 3 the 'inner end or the turn plug 47.

Rigidly connected to the outer end et the turn plug is a milledhead 52 which is of suilicient internal diameter to embrace and renali/"eA around the outerlend oi the body the said head 52, together with the body 32, being graduated, as shown at 53 and ed., respectively, the graduations 5e being intended to represent the airl pressure in pounds, so.. that by turning the head 52, any desired rpressure in pounds may he obtained in the air regulating chamber l2 By turn the head 52, the turn plug is `Lei/'oli' and pushes inward on the spring i I cordingly exerts a greater or less l lug inserted in a threaded v Lozsgelii against the plunger head' 49, and in turn against the dlaphragm, .tending to2 open the port through the valve seat 4l; 0n the other hand, the spring 38 Abehind the valve 37 opposes the action of the spring 50. Air enters the. chamber 4t2 through an .air .inlet port 55 and emerges therefrom through a port 56 which leads bach into the main air lfroin the foregoing description, it will now be seen that the air passing downward thro'u h the duct 27 passesbyv the valve 37 and t rough the chamber 4:2 and port 56 into the end portion ofthe duct 27, and thence inte the gasolene tank. Should the air pressure in the tank diminish ilo-'any considerable extent, the pressurevv in the chamber 42 will be correspondingly reduced,

thereby allowing Athe spring 50 to move the plunger head and thereby force the diaphragm 43 against the endof the valve 37,

unseating said valve and allowing the full 'ainpressure to enter the chamber 4-2. As

soon as the pressure is restored, the valve 37 closes and shuts od' any-'further increase in pressure. In this Way, a certain prede terin'ined pressure is always maintained in the gasolene tank, which will insureV the proper dow-'o -ga'sclene under pressure to the needle yvalye 24:.
