To all whom #may concern Be it known'that I, J AMES E. FLiToRor'i, a citizen ofthe United States, residing at Ocean Gro-ve, in the county of Monmouth and. State of -NewjJerseyhave invented a new and useful lGrasolene Blow-Torch, of which the following isa spec'iication.

The present invention relates to improvements in gasolene blow torches, the primary is the provision of a novel form of air supthe chamber will be tapered to a fine point to'v 'render the torch especially adapted'for braz'- object of the present invention `being the provision of a blow torch having a novel form of gas and air mixing means disposed in operable relation to. thef'gasolene supply Valve, the said means terminating in an'enlarged` cylindrical combustion .chamber having a flame reducing grid or baiiie, wherebyflame emitted fromI the combustion ing andother workwhich requires the concentration of an intense heat. A further object of the present invention plying pump having mounted in the lower end thereof a spring closed valve which prevents the entrance of the liquid or gasolene within the reservoir of the lamp from enterplunger.

body or tank A still further object of the present invention is the novel arrangement and positioning of a handle, said handle being` disposed at such an angle with relation to the torch as to render the manipulation or direction of the flame to the object to be heated more easilyfsaid handle'being so disposed as to render the manipulation of the torch more natural and so that the operator is permitted tor grip thev handle at an angle of substantially 45 or 'upright position of the torch.

rwith the foregoing alia other pbjeasijin form of lockingv means'being dis-- position, at WhichI time the.

degrees to the' body of view'which will appear as the description proceeds, the invention resides in the comthe details of vconstruction hereinafter described and claimed, it being understood that `changes in the precise embodimentv of invention herein disclosed can be made Within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawingsnFigure l'is a vertical plete torch, the Valve being in losed position, with the pump plunger locked in in ,most or down stroke position. Fig'. 2 is a section taken -on 3 is a section taken on line 3`3 of-Fig.l 1. -Fig. 4 is a section through the upper end of the air pump, at right angles to the. sc 'ction shown in Fig. 1v. Fig., 5 is an enlarged deair supplying pump showing the construction-of the valvesand mountings thereof.

lactuated valve mounted at the extreme'lower end ofthe pump.,v

Referring to the drawings, .designates the tank or reservoir which is oi. the usual construction and is provided with the hollow or arm .4 being connected upon the same side 'of the tank or reservoir 1 as the boss 2, .andprojecting outwardly in a line parallel `with the bottom or lower edge of the tank and carryingremovably at its' upturned end 1l the gripping handle 5 whose upper end is 'held b'y .means of the lug 5 Jformed integral with the yexterior of the boss 2, so

a line drawn parallel with one of the walls or a line taken through ythe center of `the tank 1.y By this means the operator grip- III iivitmore ease and without a `tiring effect, than where the handle is mounted i n a vertical line and parallel to the center line of the tank or reservoir.v y

Mounted within liquid hydrocarbon.` conveying `tube 7 sebination and arrangement of parts and inV longitudinal sectional View lthrough the conithe numeral 1n the handlev 5 can manipulate the torch' the tank is 4the yusual line 2-2 of Fig. 1. Fig

-tail sectional View of the lower end of the ,75 Fig. 6 is a perspective View of the spring y boss or projection 2 having I the upper exteriorly threaded end 3, a brace 'y `tliatthe center line of thehandle will be at an angle of substantially 45 degrees from 'cured' bythe washer, while disposed there- 4 above and in linc with the outlet aperture 9 is the torch carrying standard or tube 10.

' A wick 11 is disposed in both of the tubes 7 and 10. By this means the gasolene Within the tank is iiltered as it is forced through the wick in the tubes 7 and 10 to the torch body 14, thus preventing the burneufrom being clogged and at the same time assisting in an even flow of gasolcne to the torch body 14, which is connected by means of its tubular boss to the upper cud 12 ot' the standard l0, said standard 10`turtl1er Carrying the drip cup 13. Mounted in the top of the tank or reservoir is a removable cap G, whereby the tank may be filled with the gasolene or other iuid hydrocarbon.

The torch body 14 has formedtherein the liquid hydrocarbon conveying channels 16 and 17 which terminate in the concentrically disposed tapered outlet 1S controlled by a needle valve 19, the stem ot' whichv is mounted through the projecting end 20 and stutlng box 21 and is provided with the operatingT wheel or handle F22. The fluid hydrocarbon under pressure when supplied to the torch body is admitted from the end of the tapered bore 18 concentricall)7 of the enlarged air and gas mixing chamber 23, which is provided with the series of air inlet elongated slots 24, said chamber being made substantially in the fornaci two oppositely disposed truncated cones, whereby the air, due to the projection ot thetlow or stream ot iluid hydrocarbon into the eductionftube or bore 25 of the main body 14, will be drawn through the longitudi- ,nally disposed slots 24 and be thoroughly mixed within said chamber and the eduction tube 25 before' the entrance of the carbureted air into the enlarged 'cylindrical combustion chamber 26 formed at the eX- treme' outer end ofv the torch body 14. Through the walls of the cylindrical combustion chamber are provided a plurality of equidistant-ly spaced apertures 27, while mounted removably in the open end o' the vcombustion chamber is a disk' 28, which,

through the medium of the removable screws 29 .is fastened in the outer end of the combustion chamber, asclearly shown in Fig. 2. This disk is provided with the concentrically disposed aperture 30- having radiating therefrom the plurality of radial slots 31, which provide a means for splitting the partly burned gases, said disk 28 being a baille plate whereby'the flame due to the shape of the same and the radiating slots 31 is caused to taper outwardly from the extreme end of the combustion chamber to an exceedingly sharp point, thus producing the desired pointed vflame for brazing and other purposes.

In order to supply the properamount of air and the consequentpressure to the contents of the tank or reservoir 1 to properly feed the' spray of `fiuid hydrocarbon into the torch body', the .removable pump cylinder 32 is disposed within the bore of the boss, 2 of the lamp bodyhthe rim 33 of said cylindrical pump body being disposed to receive the washer 33 'and with the cap'or cover 34 properly seats the said pump within the bore and secures the saine air and liquid tight upon the upper extreme end of the hollow boss' 2 of the lamp. The removable cap 34 is provided with the concentric aperture 35 through which is slidably mounted for rebeyond the plunger 39 is a concaved disk 40 ixed upon, to seal the upper end of the truncated conical casing 41 which is removably mounted in the concentric aperture in the lower end of the pump cylinder 32 and projects within the body to be engaged or incased by the cupped portion of the concaved disk 40 when the plunger is locked in*vl the position as shown in Fig. 1. Formed coneent-rically and integrally with the inner end of the valve carrying casing 41 is the re-\ duced tube 42 forming the air outlet for the pump and providing upon its lower. end a seat for thewalve 47 which is mounted within the removable tube 44, whose upper end is threaded intothe open end of the valve casing 41, said tube being provided -with the air outlet aperture 45 in its lower end and having mounted therein the spring 46 which normally bears upwardly upon the lower side `of the valve 47 to hold the same in' valve seating position with the lower end of the, tube 42, a leather seat 48 being carried by the valve 47. The said valve 47 is provided with the spring and spaced terminals 49 which ride upon thev wall of t-he tube 42 and thereby properly guide the valve 47 into and out of seating relation and also when forced downwardly', due to the in-stroke of the plunger 39, slides downwardly upon the stem 42 to permit the emission 'of air through the s aces lbet-Ween the arms into the tube 44 and ignally into tank. By this construction it will be seen that upon the downstroke of the plunger 39 the air.will be forced within the tank or reservoir 1 and `that by reason of the spring 46 and the valve 47, that upon the up-stroke the pressure within the tank and the said spring will close the said valve 'to prevent any leakage of air or the liquid into the `pump cylinder 32, thus preventing any action that tends to push the plunger upwardly into extended position or'up-stroke, as is the general faultf with most blow torches.

iso,

In order to lock the plunger in its downward position and.thereby place it out 'of the way in manipulating the blow torch, the oppositely .disposed integral lugs 50 are formed upon the boss 2 while pivotally connected thereto is the bail 51, preferably'made of wire and provided with the spaced terminals 52 with the eyes 53 u on the ends thereof, said eyes being pivota ly mounted upon the respective lugs 50, so that the coils 54 carried by the bridging portion of the bail 51 may be brought into and out of contact as at a with the outer end of the button or handle 3S of the plungerstem, thus retaining the plunger stem in the down .orinstroke position, and as the-said coil 54 permits a yielding tension upon the upper end of the knob or handle 38, the said plunger 39 is held yieldingly downwardly into valve se ting position, thus locking the same in an im# movable position and permitting the ready manipulation of the torch by means of the handle 5 without any'interference from the upper end of the plunger stem.
