TORCH.

Specification of Letters Patent.

Patented Apr.. 12, 1916..

Application led November 26, 1913. Serial N o. 803,225.

fl' 10 all whom t may concern Be it known that I, FRANK LrrTnR, a citizen of the United States, residing` at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Torches, of which the following is a specification.

This invention relates to torches and more particularly to pocket torches, the principal object of the invention being to provide a novel, simply constructed, cheap and durable device which may be conveniently carried in the pocket and which is especially advantageous for obtaining light in small or inaccessible places.

Another object of the invention is the provision of a novel type of burner and retort.

Further objects of the invention will apppear as the following description is read in connection with the accompanying drawing, which forms a part of this application, and in which:-

Figure 1 is a side elevation. Fig. 2 is a vertical sectional view therethrough showing the closing cap in dotted lines.

Referring more particularly to the drawing, 1 represents a casing or tank to which is secured a closing cap 2, comprisingF a hollow body portion a having a concaved or slightly rounded upper surface 13 and a depending flange 14: of less diameter than the body portion said flange being spaced therefrom and threaded for engagement with the filling opening 1 in the casing 1. Secured in the depending flange is a wire mesh wick covering extending from the flange 14 to the bottom of the casing 1. Mounted centrally of the curved upper surface 18 of the closure cap 2 is a long longitudinally extendingl burner or wick tube 3, said tube being adapted to extend below the convex surface 13 of the closure cap for a short distance and coperate with the hollow body portion a of said cap to form a gas collecting chamber or pocket 15 adjacent the entrance of the wick within the tube 3. Removably mountedupon the upper end of the burner tube is a burner, generally :indicated at 4, consisting of a tube 5 arranged to fit over the burner tube 3 and having` a circular series of pin hole apertures 6 through which the gas will be ejected, as will be more clearly understood hereinafter. The upper end of the tube 5 is closed and surrounding the same above and below the series of apertures 6 are heat conducting disks 7 and 8 which serve to absorb the heat from the flame and cause pressure in the tube 3 and tank 1 by expansion of the gases therein.

The casing 1 is preferably lined with cotton 9 or other suitable absorbent material and a wick 10 is fitted into the tube 3 and extends down into the receptacle 10 so as to conduct the fumes from the gasolene or other similar volatile oil to the burner openings 6.

ln practice, casing 1 is preferably provided with a pair of diametrically arranged studs or projections 11 which are adapted to be engaged by bayonet slots formed in the closing cover 12 which is used to protect the burner tube when the device is not 1n use. ln the operation of the device, the receptacle or tank 1 is filled with any suitable type of volatile oil such as gasolene andl this is preferably used owing to its comparative cheapness. After the wick and lining have absorbed as much gasolene as they will hold the loose fuel is emptied and the cap 2 applied, while the pocket or gas collecting chamber' 15 the greater portion of whose surface is exposed to the atmosphere insures a. sufficient and steady flow of moderately heated gas through the wick tube to prevent flickering of the flame, and to avoid the liability of explosion within the reservoir 1 from a super-heated closure cap. By holding a match or other flame beneath the heat conducting flanges the gas in the upper end of the tube may be properly expanded to secure the desired pressure with in the tank 1 and cap 2. rlhis pressure will cause the expulsion of the gas through the pin hole openings 6 and when once lighted the light from the flames will constantly generate sufficient pressure to insure an ample feed. A burner of this character is calculated to give a six power candle light when the wick is lowered below the end of the tube but when the wick is raised to make a small gas space the action will be to increase the size of the flame owing to the in creased pressure in the small gas chamber in the tube or burner cap 5, while the end of the wick tube within the cap 2 acting in conjunction with the flange upon said cap will prevent the wick from entirely filling the pocket 15 in the cap 2.

No provision has been made for raising or lowering the wick but it will, of course.

rio

be understood that any suitable type of device may be employed for this purpose or the Wick may be lowered by pressing the saine downwardly vWith a match.

What is claimed is A device of the kind described, comprising' a casing, a central inwardly disposed nipple yformed upon said casing` and providing an opening therein, a cap adapted to close said opening and provided with a threaded collar engaged with said nipple, an elongated upright Wick tube connected to said cap and terminating therein, a Wire mesh tubular Wick holder secured to the collar of said cap and disposed concentrically in said casing and extending` so as to engage the bottom thereof, absorbent material completely filling said casing and surrounding` the length of said Wire mesh wick holder, and a wick securely mounted throughout the length of said Wick holder, so as to engage the bottom of said casing, said wick being' reduced in length and snugly iitted in said Wick tube.

In testimony whereof I aiiix my signature in presence of two witnesses.
