.acter and which can be employed with particular advantage in welding.

The invention consists in the details of construction and in the combination and arrange-4 ment oi theseveral parts ofmy improved heating torch whereby certain important advantages are attained, as ill be hereinafter more fully setforth.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawing. wherein:

Figure 1 is a view in elevation, with portions broken away, of a heating torch constructed in accordance with an embodiment of my invention;

Figure 2 is an enlarged fragmentary view, partly in section and partly in elevation, particularly illustrating the means herein comprised for fffw/mixing a volatile fuel with the acetylene gas; and

Figure 3 is a detailed sectional View 'of the .iet taken substantially on.the line 3-4 of Figure 1. As disclosed in the accompanying drawing, I denotes a tank or reservoir'of desired dimensions and preferably of a ilve gallon capacity, although lt is not desired to limit the invention in ated within the tank or reservoir I may be readily and conveniently determined.

The bore 9 of the carry-ofi pipe 6 delivers within the upper portionof a container Il of suitable dimensions and which is preferably of glass, although it is to be understood that the invention is not to be limited to any particular material. Depending from the bottom wall of this container III is an outletl nipple II, the iiow through which is under control of a conventional valve I2.

this respect. The wall of this tank or reservoir I Y v carries, .at a desired point, a conventional valve controllediilling stem 2 to provide means where'- by water or air may be forced within the tank or reservoir I as desired.

The-top wall 3 o i the tank or reservoir I is provided with a relatively large opening 4 which is normally closed by aplug 5, or otherwise as may be preferred. This opening 4 constitutes.

an entrance whereby carbide may be placd within the tank or reservoir I as required.-

In communicationv with and extending laterof the reservoir or tank I, and supported by the wall thereof, is a carry-of! pipe 8, the now through which being 'under control of a conventional valve 1. Thepipe 6, at a'point between the tank or reservoir I and the valvel, has in communication therewith a gauge 8 whereby the vpressure of the gas gener- Extending upwardly from theplpe 8 is an upstanding discharge pipe I4 for the vfuel mixer. Within the upper portion of the container I0 is a suction tube I5 having its inserted end portion ldisposed downwardly, as at I6, within the container I0 to extend below the level o! the gasoline -within the container I0. This tube I5 is continued by a port Il which communicates with the bores I8 of the discharge pipe Il. The wall of the tube I5. at the top of the depending portion I6, is provided with an opening I9. The

now out through the tube I5 to the port I'I of the pipe I4 is under control of a conventional"I valve 20.

Carried by the upper end of the discharge pipe Il is a. hollow spherical member 2| providing a chamber which serves to catch any overflow or vexcess gasoline. The member 2I is provided with a discharge nipple 22 to which is coupled an angular pipe ixture 23. Leading from this xture 23 is a. nexible hose 24 provided at its outer end with a Jet nozzle 2 5, said nozzle 25 being formed to provide a hand hold 26. With the valves `I and 20 open the acetylene gas generated within the tank-or reservoir I will pass through the bore of the pipe 6 into the container I0 and through the opening I9 into the port I1 and out through the pipe Il and its associated parts to the jet nozzle 25. This travel oi' the acetylene gas will also result in drawing up through the depending portion I6 of the suction tube I5 a certain amount of the gasoline or kindred volatile liquid within the container III, and thereby materially enriching the fuel when delivered to the jet nozzle 26,

thus assuring an effective name.

From the foregoing description it is thought be obvious that a heating torch constructed the auxiliary tank, pipe the said other end of the tube for conducting fuel tained at a predetermined level, means for conducting gas under pressure from the first tank into the auxiliary tank above said level, a suction tube disposed vertically in the auxiliary vtank and having one open end near the bottom of the auxiliary tank and leading out therefrom above the fuel level, means connected with the other end of said tube for conducting fuel to the burner,v and an inlet opening in the tube above the liquid level by which the fuel gas under pressure may pass into said conducting means.

2. Apparatus for supplying fuel to a burner, comprising a. tank for fuel gas under pressure, an auxiliary fuel tank in which liquid fuel is maintained at a predetermined level, means for conducting gas under pressure from the first tank into the auxiliary tank above said level, a suction tube disposed vertically in the auxiliary tank and having a portion opening at one end near the bottom of the tank and having a portion of`its other end extending laterally through the wall of means connected with to the burner, and the wall of the'tube having an opening therein in a position to admit fuel gas under pressure from the upper part of the auxiliary tank at the angle between the two portions of the tube and in line with the second portion of the tube, whereby to create a suction effect through the first mentioned portion of the tube to draw liquid fuel therethrough and into the fuel conducting means.

downwardly 3. Apparatus forsupplying fuel to a burner. comprising a tank designed to contain fuel gas under pressure, an auxiliary tank designed to contain a liquid fuel at a prescribed level, a cou- Dling member between the twoV tanks and having two passages therein, each passage leading at one end into the auxiliary tank above said level. one

passage leading from the gas tank and the other passage opening laterally through said coupling membena suction tube in the auxiliary tank and having two right angularly related portions, one of said tube portions being connected in the said other passage and the other portion extending inf@ the tank to a point adjacent the bottom thereof, tubular means connected to the lateral opening end of said other passage for conducting fuel to the burner, and said suction tube having an opening therein in the convex side of the-angle between the two portions thereof for admitting gas into and substantially on the axis line of the said one of the tube portions.

4. Apparatus as setv forth in claim 3, in which the said tubular means has a portion extending vertically from the coupling member and includes as a part of its structure a globe designed to receive liquid fuel which may be drawn into the tubular` means to prevent passage of such liquid fuel to the burner.

5. Apparatus as set forth lin claim 3, and with a shut-off valve in each of said' two. passages for controlling the flow of fuel therethrough.
