HEATING STOVE.

Application med October This invention relates to vapor burning stoves and particularly to that class of heating stoves in which liquid hydrocarbon is Tfrporized mixed with air and burned as a It is desirable to conveniently locate the supply tank or receptacle in such a manner that it may be readily removed from the stove structure for the purpose of inspection and repair and for the purpose of lilling the tank so I have provided a novel unitary structure consisting of a tank, a vapor generator, a drip pan and an insulating plate all of which are rigidly secured together so that the unitary structure may be applied to the stove with the vaporizer in line With Bunsen tube of the burner proper. Therefore the movable part Will maintain proper cooperation with the immovable parts with the stove structure. The advantage of removing the tank and with it the yvapor gen erator will be apparent as the nature of the invention is better understood, referencebeing had to the accompanying drawings, in

Fi ure. 1 is a front view of a stove to whic my invention may be applied.

Fi ure 2 is an end view showing the door for t e space which encloses the removable unit.

Figure 3 is a cross sectional vievs7 through the stove.

Figure 4 is an enlarged elevational view of the removable unit, and

85 Figure 5 is a plan view of the burner, the vapor generator, the drip pan and the baiile plate, the stove case being shown in horizontal section.

The actual construction of the stove casing'is immaterial but is here shown as having a back Wall 1, a front Wall 2 and

end walls

3 and 4. The front wall 2 has an up-u like. In front of the'member 10 supported upon the bracket 9 is a burner shown as comprising a manifold 11 with a goose neck 12 at one end consisting of a Bunsen tube or mixing tube to receive the vapor under pressure and mix it with the air prior to introduction into the manifold. The actual cons, 1925. serial no. $0,248.

structionof the burner is not a part of my invention since it has been used heretofore. The burner 12 may have burner tips 13 to aline with radiante 14 similar to those used in gas stoves or heaters.

The front plate 2 and the back plate 1 support guides 15 and 16 which in turn supportthe longitudinal edges of an insulating plate 17 which carries the tank or receptable 18, the latter being suspended from the plate 17 by straps 19. The insulating plate supports a drip pan 20 which is superposed above it and which in turn supports a vaporizer or generating tube '21 through the medium of the

brackets

22 and 23 fastened to the drip pan 20 and the vaporizing tube 21 in any appropriate manner. The tank 18 has the usual filler cap 24, a pressure gage 25 and a pressure pump 26. The outlet for the tank 18 communicates With a flexible hollow wire or conduit 27 discharging into the generator tube 21 at 28, the port being controlled by a valve 29 as is Well understood.

It Willbe noted that the tank 18 the drip pan and the vaporizer may all be Withdrawn as a single unitary rigid structure and that the vaporizer 21 is supported wholly by the

brackets

22 and 23, this being desirable because the tube 27 is usually of line hollow Wire and it therefore cannot of itself support another element. It will also be observed that the Bunsen end of the burner 11 is4 .so disposed that when the removable unit is moved longitudinally into the stove casing thatthe end of the generator 21 Will aline with the inlet end of the Bunsen tube. It will further be observed that there is a. priming pan 30 on the front edge of the burner 11 into which raw gasoline may ow from the. manifold 11 to furnish sullicient fuel to initially heat the generator or vaporizer 21 and since the gasoline flows through the holes 31 it will be apparent that after the gasoline is vaporized and mixes with the air and entersthe manifold 11 that it will pass out through the holes 3l in the form of vaporous fuel, and that it will remain in vapor phase so long as the generator 21 is being heated. This it will do during the entire time the burner 11l is functioning be- -cause the vapor passing from the holes 31 will maintain the vaporizer or generator 21 hot enough to change the fuel from the liquid phase into the Vapor phase.

WhileIhave described the structure illustrated more or' less'in detail the essential part of my invention is the rigid unitary structure including the tank whichy may be conveniently removed from the stove casing and as conveniently introduced. into the stove casing without requiring tools for the removal or application of the same, generator etc. I am aware 'that prior to my in-v ventionfuel tanks have been utilized and that removable fuel tanks have been associatedwith heating stoves but the structure contemplated by my invention has not heretofore been employed.
