EMANUEL FOLGMAN, OF BROOKLYN, NEW YORK.

TORCH.

Application filed October 22, 1921.

To all w 710m it may concern Be it known that I, EMANUEL FoLcMAN, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Torch, of which the following is a full, clear, and exact description.

The present invention relates to new and useful improvements in self-blowing torches, and it pertains more particularly to an improvement on the torch shown and described in United States Letters Patent No. 1,330,696 and No. 1,379,544, granted to me February 10, 1920, and May 24:, 1921, respectively. In the torch shown and described in these patents, it has been found in actual practice that during operation, a pressure is generated within the main fuel chamber, and that when the flame is extinguished this pressure being relieved through the wick tube, forces fuel ahead of it owing to the wick being saturated with said fuel, and causes a discharge of the fuel through the burner open %t is the primary object of the present invention to provide means for relieving the pressure in the main fuel reservoir without causing a discharge of fuel from the wick in the wick tube.

It is a further object of the invention to so construct this discharge element that it is bodily removable from the wick tube for the purpose of cleaning and the like.

lVith the above and other objects in view, reference is had to the accompanying drawings, in which Fig. 1 is a view in side elevation of a portion of a torch constructed in accordance with the present invention;

Fig. 2 is a detail View partly in section of the wick tubes of the torch described in the aforementioned. patents, said view showing the improvement in place therein.

Referring more particularly to the drawings, the reference character 5 designates the body of the torch, and the upper portion thereof as shown, forms the main fuel reservoir of the torch. Leading from the top wall 6 of the main fuel reservoir is a wick tube 7, and said wick tube forms an overlying retort for a burner 8. The reference character 9 designates the burner pipe, and said burner pipe 9 is provided with a discharge opening 10.

Mounted in the wick tube 7, is a wick 12,

Serial No. 509/1663.

and in practice the wick is saturated with the fuel in the body 5 of the torch, it being understood that said wicks extend downwardly thereino. In the present instance, a small vent tube 15 is mounted in the wick tube 7, and occupies a position preferably between the wick 12 and the outer wall of the wick tube in which it is placed. This vent tube has its upper end extended to a point adjacent the burner cap 16, and is provided with a loop or the like 17 with which a suitable tool may be engaged in placing or removing said vent tube 15. The lower end of the vent tube 15 terminates at a point substantially flush with the upper wall of the main. reservoir 5, and this tube serves to establish communication between the main reservoir 5 and the passage 30 of the burner cap 16.

The device operates in the following manner:

During the operation of the torch as heretofore stated, a pressure is generated within the main fuel reservoir 5 and when the torch is extinguished said pressure in passing through the wick tube 7 forces the liquid fuel with which the wick is saturated, through the burner opening 10. When, however, the vent tube 15 is positioned in the wick tube 5, immediately upon extinguishing the torch, the pressure in the main fuel reservoir is relieved by the vent tube 15, said pressure passing through the vent tube to the passage 30 of the burner cap, and from thence to the burner tube 9 and out through the burner opening 10 thereof.

By this construction it is apparent that the pressure in the main reservoir is relieved without passing through the entire length of the wick in the wick tube. and, therefore, the pressure is relieved without a discharge of fuel through the burner opening, as is the practice when the vent tube is not employed.

lVhile in the present embodiment of the invention, the by-pass tube has been shown as positioned within the wick tube, it is obvious that the same be exterior thereof without departing from the scope of the present invention, since a tube of this character could be employed to discharge directly into the atmosphere on the exterior of the wick tube, if desired.

I claim:

1. In a torch of the class described, a main reservoir, a wick tube, said wick tube having one of itsends formed, with a discharge opening, a vent tube carried by said Wick tube and conforming to the shape thereof, said vent tube extending throughout the wick tube from the main reservoir to the discharge opening thereof and means having one of its ends formed With discharge opening, means for by-passlng pressure in the main reservoir, said means comprising a by-pass tube adapted to establish communication between said reservoir and the atmosphere and a loop associated with said by-passing tube, said loop forming means for engagement With a tool to remove the by-pass tube from the wick 20 tube.
