3 Claims.

The present invention relates torches.

It is an object of the invention to provide aertain improvements over the U. S. patent to Car1e- 5 tun, N0. 901,307, dated October 13, 1908.

It is a pa rticular object cf the invention to provide an improved form of such a torch in order to permit its use with so-called ordinary or straight gasoline, the improved form of torch 19 being useable as well with so ca1led high test gasoline, but its use being not necessarily restricted thereto.

The invention comprises a member cooperating with the torch spout and providing therefor a preheating chamber because of which the torch is enabled to operate satisfactorily and eflectively with fue1 other than high test gasoline.

Other features and advantages of the inventidn are hereinafter more fully described in connecto, hydrocarbon tion with the accompanying drawihg, which illustrates a preferred embodim6nt of the invention and in which the Figure 1 is a side elevation with a threaded. filling opening into which, a.nd containing the wick 12, is screwed the spout member 15 o1 the torch. The spout member 15 is provided at its lower end with manually operable turning wings 16' by means of which th e the drawing and is provided on its under side,

including the under side of the bent portion, with a series of indentations forming ridges, and at its upper end is provided with screw threads 19 for attachment thereto of a burner sleeve 21 "The burner sleeve 21 is provided intermedimte its ends with cooperating screw threads 22 and is also provided, between said screw threads and its upper open end, with a plurality of air admitting openings 24. In accordance with the present invention the bumer sleeve 21 extends downwardly or rea.rwardly beyond its screw threads 22 around the upper end cf the spout 15, being spaced from said spout and thereby providing around 'the upper end of the spout a preheating chamber 25.

; It will be understod tha.t the upper end of the limited to use with such fuel.

includes a fuel reservoir 13 provided a.t its top' spout isclosed except for the usua1 smal1 blow hole. The provision of the preheating chamber 25 makes it possible to use other fuels than high test gasoline with the resu1t that the torch is not In using the torch, a lighted match, or candle,

or suitable flame from any source is he1d close to the indented ridges of the spout, the heat from the flame being trapped and retained close t0 the spout; by the preheating chamber, vaporizing the fue1 with such efiiciency that fue1s other than: v high test gasoline maybe used. As soon as sufficient pressure is generated, the vapor is forced out of the spout opening, and, mixed with air in the upper part of the burner sleeve, may be ignited at the upper opening of said sleeve. 'Ihe preliminary heating of the spout may now be dispensed with1he torch flame continuing unti1 blown out or exhaustion of fuel.

By reason of the preheating chamber, after the burner is ignited, the preheating of the fue1 comtinues, being caused by the burning flame a.nd the preheating chamber. This preheating of the fue1 prior to its-combustion continues while the torch is ignited. It will be noted tha.t the p'reheating chamber surrounds that part of the feed ing tube which contains the fi1e1 before it passes out through the ignition opening. Whether or not it is the case that by reason of the preheating, fue1, such as gasoline, is vaporized before i't passes through the ignition opening, it is a fact that with -the present invention a 10W test gasoline is responsive and operable whereas, without the present invention, high test gasoline would be required. What is Claimed is: 1. A torch including a reservoir provided with a supporting base, a spout in comrnunication with said reservoir anal extending upwardly therefrom,

a wick in said spout reaching into said reservoir, 5 said spout having a b1ow hole, means on saidspout for attaching a burner sleeve thereto, and

a burngr sleeve attached to said spout extending forWai dly therefrom and forming a preheating chamber around said spout between the blow ho1e and saidreservoir.

2. A torch including a reservoir, a spout in communica.tiontherewith, a wick in sa.id spout reaching into said reservoir, said spout having a b1ow hole, meanS on said spout for attaching a 5 burne'r sleeve thereto, ar 1d a burner sleeve attached t0 said spout extending forwardly therefrom a.nd having its rearward portin surrounding said spout and spaced therefrom, providing a preheating chamber for said spout between said attachment of a bumer sleeve und a bumer s leeve attached to said spout extending forward- 1y thereo! beyond said blow hole und extending rearwardly around and spaced from said spout between sa.id threads and said reservoir thus forniing a. 15xeheating cha.mber around said spout.
