SPECIICLTION forming part of Letters Patent No. 402,409, dated April 30, 1889.

Application iilerl November 17, 1888. Serial No. 291,120. (No model.)

stoves in which the gasoline-tank is locatedA below the Vapor-generator or generatingburner, and in which the gasoline is elevated to the generator by'means ot air-pressure within the tank. In this class of devices it has been found practicable to initially heat the generating-burner or generator by a flame derived from the combustion of carbureted air; andato this end a separate pipe or passage has been provided leading from the air-space of the gasoline-tank to a point beneath or adjacent to the vapor-generator.

The present invention has reference to two features of improvement in this class of stoves.` One relates to a iitting containing passages for both the liquid and the carbureted air and the other to a device by means of which external air may, when required, be admitted into thev pipe which conveys the carbureted air `from the tank to the point where it is ignited to'initially heat the generator.

The accompanying drawing is a fragmentary view of a vapor-stove, in which the portion of the frame-shown and a generating-burner areseen principally in side elevation, but in which the gasoline-tank, the novel fitting referred to, a part of the liquidepipe, and all of theI carbureted-air pipe are shown in Vertical section.

A represents the top plate of va stove-frame, and A one of the standards.

B is a generating-burner.

C is a gasoline-tank located below the burner. y i

D is the novel fitting for giving both air and liquid passages from thetank C.

D is the stand-pipe for liquid, leading from the tank to the generating-chamber ot' the burner, and E is the upright portion of the 'carbureted-air pipe.

The fitting D consists ot a casting having an interior chamber, d, which is circular at its upper end to receive the lower extremity ot the tube or stand-pipe D in any suitable manner. As shown, the latter is provided with a collar', d', which rests on a shoulder, d2, within the chamber d, and on its upper edge affords a bearing for the nut D2, which is screwed upon the top of the fitting D. Said iit-ting has a shoulder or flange at d3, which rests upon the tank C, and is soldered thereto. It is also provided with a leg, D4, having a passage, (Z4, through it, terminating in the chamber d. This leg D4 is here shown as passing Adown to the bottom of the tank C eX ternally to the latter, and in this construction said leg is provided with a foot, D5, which laterally enters the tank near the bottom thereof, and is provided with a passage giving communication from the interior of thc tank to the vertical passage (Z4.

Within the thick wall Dn of the vfitting D is provided a vertical passage, d5, which communicates through the top of the tank with the upper port-ion of the interior of said tank, or with what may be termed the air-space thereoir, The passage d5 has a -lateral opening, (Z6, into which is screwed a horizontal pipe, e, which is provided with a valve, E. Beyond'the valve the pipe e has an opening or passage, e', on its upper side.

Surrounding the opening e is a vertcal circular ange or thimble, e2, having one or more lateral openings, e3. This flange e2 forms a socket, in which rests the lower end of the vertical pipe E. The upper end ot the pipe E is laterally supported in a corresponding socket, f, in a bracket, F, which, as here shown, belongsto the burner B, and has an opening, f', which forms the outlet of the pipe E, at which the carbureted air emitted through said pipe is ignited for the purpose of initially heating the generator of the burner B. The pipe E is sufiiciently loose in the end sockets, e2 and f, which support it, to allow ot its easy rotation, which is facilitated, desirably, by'means of a projection, say as e5, on the pipe. The lower end of the pipe E is notched or perforated, as shown clearly inthe drawing at e4, so as to register withithe hole or holes eB in the socket e2. By this means the IOO outer air may be admitted into the interior of the pipe E through said holes when the pipe E is turned in the desired position for this purpose, and, on the other hand, when the pipe E is rotated one Way or the other, so as to throw the passages out of register, the outer air will be excluded. The utility of this last part of the invention is found in the fact that at some seasons of the year the flame produced by ignition of the carburetod air is more effective it' mixed with an added quantity of external air, while at other seasons of the year itis more effective if burned alonethat is to say, in summer or warm weather the outer air may be commingled with the carbureted air with advantages to the heating-llame, and in the winter it is preferably excluded.

Manifestly, any other form of valved inlet for the external air may be employed in plaee of that here shown, the device illustrated beiig preferred principally on account of its simplicity and the eheapness with which it can be constructed.

ticular form of the contrivance here shown for the admission ot` external air to a earbureted-air pipe.

l claim as my invention- 1. The combination, with a gasoline-tank, a generating-burner, and liquid and air pipes, respectively, for supplying and initially heating the generator, of a fitting, D, having a passage extending to the lower portion of the liquid-tank and a passage extending from the upper portion of said tank, and having said passages connected, respectively, with the liquid and air pipes.

2. In combination with a gasoline-tank and a vapor-generator, an air-pipe leading from the air-space of the gasoline-tank and provided with a valved inlet for the admission of external air, substantially as described.

In testimony that I claim the foregoing as my invention I affix my signature in presence ot two witnesses.
