JAMES E. SANDERS, OF GREAT FALLS, MONTANA.

VAPOR STOVE.

Application filed July 7,

To all whom it may concern.

Be it known that 1, JAMES E. SANDERS, a citizen of the United States, residing at Great Falls, in the county of Cascade and State of Montana, have invented certain new and useful Improvements in a Vapor Stove; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

' The invention relates to stoves designed to utilize volatile hydrocarbon, such as gasoline, as fuel, the same being vaporized and consumed in the gaseous state.

The invention provides a stove of the character stated which is portable, compact and effective and which may be conveniently carried for camping or tourists use.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawing forming a part of the specification,

Figure 1 is a perspective View of a stove constructed in accordance with the invention showing the same closed and in compact form,

Figure 2 is a top plan view of the stove, the cover being open and an intermediate portion thereof broken away,

Figure 3 is a longitudinal section on the line w-m of Figure 2,

Figure 4 is a side view the rear side of the casing being omitted,

Figure 5 is a horizontal section on the line g of Figure 4,

Figure 6 is a vertical transverse section on the line 22 of Figure 4.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The stove comprises a shallow casing 1 preferably of rectangular form and constructed of sheet metal. The casing 1 is closed at its top by means of a cover 2 and at its front by means of the end piece 3 1921. Serial No. 482,979.

which is hinged to the swinging end of the cover 2, the latter being hinged at its inner or rear end to the upper edge of the back wall of the casing. This construction admits of the cover 2 being utilized as a stand for supporting utensils or other articles. The front or end 3 constitutes a support for the outer end of the cover when swung into horizontal position to form a stand or article support.

A substantially U-shaped pipe 4: is disposed within the upper portion of the casing l and constitutes a reservoir for holdin a supply of gasoline or other liquid fuel. ne

end of the pipe 4 is closed by means of a p-ug 5 which when removed admits of charging the pipe or reservoir with fuel. The opposite end of the pipe or reservoir 4 is provided with a pump 6 which provides convenient means for supplying air under pressure to the pipe or reservoir to insure a positive feed of the fuel to the burner. The pump 6 and closure 5 may be of any desired construction. A burner pipe 7 is disposed in the lower portion of the casing l midway between the members of the pipe or reservoir 4 and extends nearly the entire length of the casing. A supporting bracket 4 is suitably fastened in the casing and the pipe 4 is disposed thereon. Said bracket 4* has a deflection 4 in which the pipe 7 is disposed. The burner pipe 7 is provided in its length with openings which constitute an outlet for the gas when the stove is in operation. A feed tube 8 is disposed above the burner pipe 7 and connects at one end with the closed end of the fuel pipe 4 and at its opposite end with the front end of the burner pipe 7. The forward portion of the feed tube 8 has a return 8 in which is located the valve 9 for controlling the feed of the fuel. The portion of the feed tube 8 directly above the burner pipe 7 constitutes a generator since it is in the path of the flame from the burner and the fuel is vaporized therein. The feed tube 8 is relatively small to prevent the too rapid flow of the fuel therethrough and insure a thorough vaporization thereof. The receiving or feed end of the tube 8 is provided with a wick 10 which extends into the pipe 4 to insure all the fuel feeding to the tube 8 if necessary in the operation of the stove.

A starter pan 11 is disposed beneath the burner pipe 7 and may be supported in any lit) manner. The starter pan 11 receives a small quantity of gasoline or other liquid fuel when starting the stove so as to heat the burner pipe 7 and the feed tube 8 whereby to initially vaporize the fuel. The starter pan 11 may be supplied with fuel from the pipe or reservoir 4: through one or more openings 12 formed in the lower side of the burner pipe 7 upon opening the valve 9. A grate 13 is disposed at the top of the casing 1 and forms a rest for the utensil or other receptacle or article to be heated. \V hen the stove is not required for immediate use the cover 2 and front 3 are folded substantially as indicated in Figure 1.

Having thus described the invention, what I claim is i 1. In a stove, a casing, a burner within the casing a closure hinged at one end to the upper edge of one end wall of the casing, the end of the casing opposite to Said wall being open, and an end piece hinged to the other end of the closure whereby it may rest on the base of the casing to constitute the wall for said open end when the closure is in closed position or may support the closure when in an open position so that the closure may constitute a support for utensils.

2. A vapor stove of the character specified comprising a relatively shallow casing, an approximately U-pipe in the upper portion of the casing constituting a fuel reservoir, a grate above and resting on said pipe, a burner pipe in the lower portion of the casing extending lengthwise thereof and disposed intermediate the branches of the U- pipe, a feed tube connecting the U-bend of the U-pipe with the forward end of the burnerpipe and extending over the latter and constituting a generator, said U-pipe having a removable closure at one end and i an air pump at the opposite end for supplying the pipe with air under pressure, a supporting bracket for andextending below said U-p'ipe having a deflection in which said burner pipe is disposed, and a starterpan below said burner pipe.

In testimony whereof 1 affix my signature in presence of two witnesses.
