Application filed June 14, 1920.

1'0 all whom it may concern:

Be it known that I, CAs'rLnMAN Conn, citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Con trollable Torches, of which the following is a specification.

The present invention relates to an im proved torch for igniting the burners discharging into oil burning furnaces, and is more particularly adapted for use in con nection with the ignition of the burners situated beneath or in the boilers located on vessels, or in such places wherein a multiple or series of boilers are employed in firerooms, although the use of this invention is not so restricted, inasmuch as the same is adapted for the ignition or lighting of fires generally.

In its preferred embodiment, the torch constituting the present invention comprises a suitable tubular handle on which is mounted for longitudinal and rotatable movement 7 7 upper end of the said handle. On the handle a slidable barrel. which barrel at one end carries, or has united thereto, a snufier shell adapted on one movement of the barrel to snuff out the flame of the torch; the tubular handle at its opposite end carrying a holding reservoir or magazine adapted to con tain a quantity-or supply of the hydrocarbon fuel. employed for the saturation of waste or body of absorbent material carried at the lower extremity of the tubular handle.

The object of the invention is to provide a simple, etficient, inexpensive, and durable torch for the purposes desired, and one wherein by the use thereof the fire risk incident to the lighting of fires is reduced toa minimum.

In order to comprehend the invention, reference shouldbe had to the accompanying sheet of drawings, wherein- Figure 1 is a perspective view of the torch illustrating the snuffer in raised position for exposing the body of waste or saturated absorbent material to be ignited.

Fig. 2 is a broken longitudinal sectional view of the torch, illustrating the snufler in closed or lowered position and the valve for controlling the flow of the liquid hydrocarbon to the body of waste or absorbent material in open position, the tubular handle on which the barrel or shell carrying the snuffer and the liquid holding reservoir is mounted for movement being non-sectioned.

Specification of Letters Patent.

Patented Delay 16, 1921. Serial No. 388,807.

Fig. 3 is a plan sectional view taken on line 3-3, F ig. 2 of the drawings, and viewed in the direction of the arrows.

Fig. 4 is a detail view of the controlling valve and its stem.

In the drawings, the numeral 1 is used to designate a cylindrical handle preferably formed hollow and which carries at its upper end a liquid holding magazine or reservoir 2. At its lower end portion the said handle is perforated and closed by an enlarged head 8, and the said handle is also provided adj acent its lower end with a flanged collar 4. That portion of the tube intermediate the flanged collar 4: and the head 3 is wrapped or covered with a pad of absorbent material 4, as, for instance, waste or asbestos, which receives for saturation through the openings or perforations 5 formed in the lower end portion of the handle a supply of hydrocarbon mixture, such, for instance, as kerosene, which is delivered thereto through the hollow tubular handle from the liquid holding reservoir or magazine 2 carried at the 1 is mounted for longitudinal and rotatable movement a sleeve or barrel 6, which sleeve or barrel at its lower end carries an enlarged cylindrical shell 7 which serves the function of a snuffer on the lowering movement of the shell or barrel for the snufling out of the flame of the torch, the said shell or snufier being of such diameter as to completely inclose or house the body of absorbent material 4 when the sleeve or barrel is in its lowermost position. The said barrel or shell is provided with a longitudinally disposed slot 8, which at one end terminates in an angularly disposed notched extension 9, and at its opposite end ina similar notched extension '10, the two notched end extensions 9-10 being projected from opposite sides of the slotted section 8 of the said sleeve or barrel 6. A projecting headed retaining guide stud 11 is secured to the handle 1 of the torch, said stud projecting through the slotted section of the barrel or sleeve 6 and serving to maintain the same in position relative to the handle 1. p

The holding reservoir or magazine 2 is connected. or united to the upper end of the tubular holder 1 of thetorch by means of the threaded coupling 12, which interiorly is provided with a valve seat 13 which is openedor closed by means of a valve 14, said valve being held normally in closed position by means of the tension spring 15 situated within thesaid coupling. The stem 16 of the valve is apart hollow one,'and its tubular portion is provided withtwo spaced air ports 17 and 17'. This stem projects through a removable cap 18 forv the liquid holding reservoir or magazine 2, and this cap in turn is provided with air ports 18. lVhen the valve stem is depressed to cause an unseating of the valve, the upper air port 17 of the stem 16 is brought into registry with the ports 18 of the cap 18, thereby ad mitting air to the interior of the valve stem, which escapes therefrom under atmospheric pressure through the lower port 17, and into the interior of the holding reservoir or magazine 2 and supplies the requisite air pressure for causing the feeding of the hydrocarbon liquid from within the holding reservoir or magazine to the tubular holder of the torch, through which the same flows and escapes therefrom through lower perforations 5 for the saturation of the body of absorbent material 4 secured to the lower end thereof.

When the body of absorbent material has been sufliciently saturated with the liquid hydrocarbon, the same is lighted and provides a large flame for igniting the hydro carbon mixture flowing from the oil or burner beneath the boilers, or for the lighting of fires generally.

The invention is designed more essentorches at present employed for the firing of a handle of suflicient length, to one end of which is applied a body of waste or absorbent material, which is saturated by being dipped into a body of liquid hydrocarbon. In connection with such form of torches, no means are provided for snufling out the flame after the burners have been ignited, the usual resort being, when it is desired to extinguish the torch flame, to dip the same for quenching purposes into the body of hydrocarbon. This, at best is a crude manner forlighting the burners beneath a boiler, inasmuch as necessarily, as the torch after being dipped into the body of hydrocarbon is carried a. distance prior to being lighted, there is a drip of the hydrocarbon over the floors, and there is always the liability when the flame is extinguished of setting fire to the body of the liquid hydrocarbon. It will thus be seen that the fire risk is somewhat heavy.

By the utilization of the present invention, all fire risks are eliminated, and the feed of the hydrocarbon to the wasteor absorbent head of thetorch is absolutely undercontrol of the operatorand equally so the extinguishing or snufliing of the flame.

)VVhen the flame of the torch has been purpose, the same comprising a handle proof oil burners, and which consists essentially w material inclosing said perforated section of the handle, a reservoir at the other end of flame of the torch, and means for controlling new/s tension 9, so as to hold said sleeve, barrel 'or shell 6 in its open position relative to the absorbent head of the torch.

While the invention has been described in its preferred embodiment, I do not wish to be understood as limiting or confining the same to the detailed construction of the working parts shown and described, but on the contrary wish to be understood as claiming the invention as broadly and for all purposes as the state of the art will warrant.

It will be understood that the torch may be made in various sizes, so that its use is not limited to the lighting of burners beneath boilers, but the same may be of such size to be used in connection with the lighting of fires in houses.

Having thus described the invention what :is claimed as new and desired to be protected 3y Letters Patent is tially to take the place of the crude form of 1. A controllable torch for the described vided at one end with a body of absorbent holding reservoir to the body of absorbent material, and means permanently mounted i on the handle capable of outward longitudinal movement thereon for snufling out j the flame of the torch.
