TORCH.

Application led February 25, 1910.

To all whom it may concern:

Be it known that l, O'rro Ban'rnm a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful improvements in Torches, of which the following is a specification.

The object of my invention -is a construction of a simpleautomatic torch which can be made at a small cost and which will burn alcohol and other inflammable fluids as fuel.

In the accompanying drawing Figure l is a front view of the torch. Fig. Qis a sec tional view of Same. Fig. 3 another sectional view of a modified construction in which the torch is shown inverted. Fig. 4 is a plan view of Fig. l.

The frame ortank of the torch is made of preferably metal Aas indicated at a. The bottom of the tank s preferably slanted as indicated at c and c are openings in the tank for Athe purpose of filling and for letting the mate rial out. These openings c and c are preferably threaded and the opening c is closed by a threaded plug e corresponding to the thread in the opening c and a washer is interposed between the wall of the tank a and the plu;Y e so as to allow the plugs to tit tightly into the tank a. The outlet c is also threaded and into this opening c the burner tube f is threaded as shown in Fig. 2. lt desired, the opening c and the plug c shown in the drawing may be dispensed with and the rear wall ot the tank made solid and the tank may be filled through the outlet opening c which is the same opening holdingthe burner tube f.

The washer Z is interposed between`the frame a. and the collar m on the burner tube f. This collar m may be provided with a wingl or flange n to facilitate the operation of screwing the tube f' into the tank a. The shoulder c Inade of noneheat conducting ni'aterial may also be placed on the tube be tween the collar and the outer tube The fluid to be used, is placed in the tank a. and is taken up by packing h which may be an ordinary Wick or a non-absorbing metal wick such as steel shavings or asbestos or it may be of clay or any suitable material which will allow the fluid or gas from the tank a to pass toward the opening f. Thisl wick or packing is placed in the burner tube Specification of Letters Patent.

cut flush with the' burner tube f as shown in Figs. 2 and 3 or it may be long,T and project into the tank as in the case of' an ordinary lamp wick.

At the end of the burner tube f is a small metal plug g having an opening extending its entire length terminating at opening f. or the plug may be made solid and smaller than the inside ot` the tube to allow the zgases to pass by it. Over the burner tube f is placed an outer tube z' made of metal or stone or earthenware or any suitable material and fitting closely over burner tube f; preferably this tube vl is made of metal and has a larger inside diameter extending beyond the inner burner tube f. l do not wish to be confined however to having: the burner tubes f and made separately. They may, if desired be made in one piece as shown in Fig. 3. The handle may be secured to any'part of the tank, the tank being formed to have several bases as supports, so that when not in operating position, either ot the bases may be used as a support, so that the fluid will not be in Contact with the opening in burner.

'lhe operation of the device is as follows'. Thetank a is filled or partly filled with an inflammable fluid preferably alcohol. The fluid is taken up by the packing' l1. and if a .metal wick or nonabsorhing wick is used,

the fluid penetrates between these parts until it reaches part y. Part vf/ prevents. in case au ordinary wick is used, any portion of the wick stopping up or plugging up the hole f and this plug ,f/ also helps to produce a greater an'iount of gas when inner tube f is heated. lf a flame is now applied to outer tube 'I the outer tube z' and the inner tube will immediately warm up and after reaching' a certain temperature will cause the, fluid in the inner tube f to change into gas and it 'the flame is then moved toward the opening of outer tube 'i the gas will ignite. As these `raseswll develop in a larger degree than the. size ol the opening f will allow them to eaeape, a certain amount of force is produced by which these gases escape from opening f and beinp,i ignited, will keep the outer tube i continually heated and thus continue to create new gases. The outlet opening ln the tank being below the top line ot the fluid. the fluid thus acts as a valve for the tube f in which the gases are ei'eated and f. lf an ordinary wick is used it may be l the position of this outlet opening secures liorv a more uniform feed of the wick or packing than could be'obtained if the outlet opening were above the top fluid line and the fluid was carried upward by means of an absorbing Wick toward the outlet opening c. During the process of operating this torch the fluid in the tank will gradually grow warmer and also develop gases and as the opening f controls or checks the escape of these gases the force of the flame will gradually grow stronger and the inside of the tank not lled with fluid will contain compressed gases. The size of the burner tubes will determine the amount of gas which will develop. Should more gas develop than can be burned by the flame.' this gas will blow out the flame and the flame being out; no more heat will be created and consequently1 the development of gas will cease. If the operatorextinguishes the flame, there is for a short period some gas developed which would press the fluid into the wick and as it cannot be consumed at the outlet when there is no flame, it would naturally squirt out until all thegas in the tank and the tubehas exhausted its force. T o obviate this Ikhave shaped the tank in such a way that its position can be changed by having severa'. bases to stand on so that when not in operation the fluid will be away from the outlet opening as for instance in the position shown in Fig, 3 and consequently no more fluid can be forced out than what is taken up by the packing or wick it when the tank 1s placed in a nonoperating position.

I do 'not wish to be confined to the precise construction shown in the drawing, any

modification in theeconstruction and shape of the parts may bg made if desirable without departing from the scope of my invention. .The tank may if desired be made circular in form as shown in Fig. 4.

I claim:

1. A torch comprising a closed fluid containing tank provided with two bases constituting supports for the tank when in upright and-inverted position and having an o enino' a burner tube connected to said opening, and a packing in said tube to form a wick and regulate the flow of the liquid, said opening being located below the leve-l of the fluid in the tank when the device is in operating position and above the lluid level when the tank is inverted.

2. A device of the kind described, comprising a .fluid containing tank provided' fluid, said opening being located near the v bottom of the tank when the torch is in operating position.

3. A torch comprising a fluid containing tank provided with two bases constituting supports for lthe tank'when in upright and inverted position and having an inlet' opening and an outlct'opening, a plug litte'd in said inlet, a burner tube attached to the outlet, and a wick arranged in the tube to prevent excessive flow of the fluid to the flame when the device is in operating position, said outlet and inlet openings being located, respeptively, near the bottom and top of the tan 4Q A torch comprising a fluid containing tank provided with two bases to constitute supports for the `tank when in upright and inverted position and having an opening, a burner tube connected to said opening and located near the lower part of thetank., a' packing arranged in the tube to form a onductor and feed sufficient uid to maite. in the flame when the device is in operating position, and a wall situated in the tube and having an outlet opening.

5. A torch comprising a -fluid containing tank provided with two bases to constitute supports for the tank when in upright and inverted position and provided with an inclined bottoml and having an opening located near the lowest part of the inclination, a burner tube extending from the opening, and
