ates with the collar 22for preventing longitudinal movement of the tube 17 with relation to the sleeve 12. Moreover, this cap 23 may be employed for adjusting the sleeve 12 within the aperture 10 when the adjacent lock-nut 16 has been loosened, and this nut may be tightened for holding the sleeve 12 in its adjusted position.

From the foregoing, it will be seen that a wide range of adjustment may be had by adjusting either or both of the wick-tubes within the sleeves 11 and 12, or by means of the sleeves.

The jet cap 19 and wick-tube 17 may be of a metal having a, relatively high, heat conductivity, so tliat the heat generated by the wick 13 and applied to the elements 17 and 19 is conducted to the hydro-carbon in a wick and in the container 7. Obviously, 'such heating of the hydro-carbon causes it to vaporize and pass through the jet-opening 20. This jet-opening, however, is so small that the vapor accumulates under high pressure within the container 7 and tube 17, and passes with considerable force and velocity through the jet-opening 20 in which the flame is generated by the wick 2, and this blast not only directs the flame to the point desired, but also adds fuel thereto.

The sleeve 12 and cap 23 are preferably formed of material having a low heat conductivity, so that when the cap 23 is employed as meansfor adjusting the tube 17, the fingers of the user will not be burned thereby.

In operating the device, as the hydro-carbon becomes less deep within the container,

the change in depth of the hydro-carbon will change the amount of pressure in the container 7 and such change may be com pensated for by lowering the tube 17 into the minor hydro-carbon container, or into the hydro-carbon contained therein, and the wick-tube 13 may be adjusted accordingly.

From the foregoing, it will be seen that I have provided a device ofth'is character which is thoroughly practical, and fully capable of effecting the foregoing objects,

- and because of the advantages obtained by this construction and arrangement of parts, this device is meeting with very considerable commercial success.

Although I have described this embodiment of my invention very minutely, it is to be understood that this invention is not limited to these exact details of construction and arrangement of parts, but that I am ontitled to make such changes as do not constitute a departure from the inventive ideas disclosed in the foregoing description and following claims:

What I claim as my invention is:

1. A blow-torch comprising a relatively long and narrow liquid fuel container having closed ends one of which is provided with two apertures, a wick, a tube extending through one of said apertures and containing said wick, a second liquid fuel container in open. communication with the other one of said apertures, a second wick, a second tube, and a jet-cap on said second tube, said. second tube containing said second wick and having one end in said second container and having its other end normally extending to a point substantially in alinement with the longitudinal central line of the first said tube. 1

A blow-torch comprising a relatively long and narrow liquid fuel container having closed ends one of which is provided with two apertures, a wick, a tube extending through one of said apertures and containing said wick, a second liquid fuel container in open communication with the other one of said apertures, a second wick, a second tube, and a jet cap on saidsecond tube, said second tube containing said second wick and having one end in said second container and having its outer end portion curved so as to normally extend to a point in alinement with the outer longitudinal central line of the first said tube, said second tube being turnable to a position in which its outer end is out of said alinement relative to the first said tube.

3. A blow-torch comprising a relatively long and narrow liquid fuel container having closed ends, one of which is provided with two apertures, a wick, a tube extending through one of said apertures and containing said wick, a second liquid fuel container in open communication with the other one of said apertures, a' second wick, a second tube, said second tube containing said second wick and having one end in said second container and having its outer end curved and provided with a jet-opening normally in alinement with the length of the first said tube, the major part of the second said tube being substantially parallel with the first said tube, and means for efiectin adjustment of one of said tubes with relation to the other said tubes.

4. A blow-torch comprising a liquid fuel container, a wick, means for holding and adjusting said wick in said container, a second liquid fuel container secured to the first said container, a second wick, and means for holding said second wick in said second container and for cooperating with both of said wicks in creating a blast for blowing flame arising from the first said wick, the

last said means being operable to move out.

of cooperative relation to the first said means so as to allow free access to the first said wick for covering thelatter.

5. In combination, an integral structure comprising a major container and a minor container, each provided with a threaded aperture, a threaded sleeve adjustable in the aperture of the major container, a tube extending through said sleeve into the major container, a Wick in said tube, a threaded sleeve having its threads adjustably. engaged with the threads of said aperture of the minor container, a tube having a collar fixed thereon, a nozzle in the last said tube, a wick in the last said tube, and

means cooperative with said collat and with the last said sleeve for eflecting'adjustment of said nozzle with relation to the first said container, a wick in said tube, a threaded sleeve having its threads adj'ustably engaged with the threads of said aperture of the minor container, a tube having a collar fixed thereon, a nozzle on the last said tube, a nick in the last said tube,'and combined packing and adjusting means cooperative with said collar and with the last said sleeve for effecting adjustment ofsaid nozzle with relation to the first said Wick.

In testimony whereof I have 'hereunto' set my hand in the presence of two subscribing witnesses.
