HEATING STOVE.

Application filed September 22, 1927. SerialNo. 221,238.

This invention relates to heating stoves in which liquid fuel is .converted into the vapor phase before it enters the burner. In such stoves, a heat responsive vaporizer, commonly called a generator, communicates with a tank containing liquid fuel under pressure. The liquid fuel forced into the vaporizing generator by the pressure within the tank is Va porized and passes into an intake port in a burner where it is burned. The tank obviously must be filled from time to time, so I have provided a novel removable unit consisting of the tank, a vaporizing generator and a heat insulating plate for the tank, all arranged in a unitary structure so that the unit can be conveniently removed for filling the tank, for inspection and repairs of the parts thereof and for testing the same. The vaporizing generator must of necessity be preheated in order to vaporize the liquid when the fuel from the burner is first ignited, so I hate provided a preheater which may be a part of the unit. This preheater can be conveniently carried by the insulating plate which serves to insulate the heat from the tank to thereby prevent the highly volatile liquid from becoming dangerously hot.

I have found it expedient to make certain other improvements in a vapor generating stove, all of which will be specifically referred to hereinafter, reference being had to the accompanying drawings in which Fig. 1 is a front elevational view of a stove constructed in accordance with my invention, parts bein broken away to better illustrate certainot er parts. Fig. 2 is an end view of the stove, the end door being swung into open position.

Fig. 3 is a perspective view of the removable unit and Fig. 4: is an enlarged view of the preheater; partly in section and partly in elevation.

Referring, now, to the drawings by numerals of reference, 1 designates the casing- 9. The unit is best illustrated in Fig. 3' as comprising a tank 10, carrying bands 11 and 12 which support a pump 13 having a conduit 14 leading into the connection 15 communieating ,.with the tank. The connection is provided with a valve 16 closing ofl communication between the conduit 14 and the tank when the pump has supplied sufficient pressure. There is a pressure gage 17 also communicating w1th the connection 15.

Leading from the tank 10, below the liquid level thereof, is a connection k8 having a valve 19 which is adapted to open and close communication between the tank 10 and a conduit 20, connected to a vaporizing generator 21, supported by the brackets 22 and 23, carried by the heat insulating plate 24 for the tank supported by the bands 11 and 12. The vaporizing generator 21 has an outlet tip 25-which can be opened and closed by a valve (not shown) on the end of the stem 26. The stem may be operated by a hand wheel 27 The particular construction of the generator is not shown nor described because such vaporizing generators are well known. 'The'preheater is shown as consisting of a reservoir or base 28 secured to the plate 24 by a fastening device 29. The particular construction of the preheater constitutes no part of my invention as the one selected for illustration has been in use prior to my invention. Briefly, it consists of a reservoir 30 adapted to be supplied with fuel through an opening 31. The liquid is carried up into the space between the tubes 32 and ings 35. The fuel can be ignited above the wick and since the preheater is below the generator, the generator will be initially heated so that the liquid supplied'from the tank will be vaporized. After the fuel from the burner 2 is ignited, the flame passing out of the orifices 5, oflset from,-and communicating with the burner manifold, will im pinge upon the generator 21 and keep it hot enough to vaporize the fuel in the vaporizing generator so long as the stove is in operation. The tank can be filled with liquid through an opening closed by the filler plug 36. The unit can be introduced into the stove by sliding it along the guides 6 and 7 until the ti 25 of the vaporizing generator alines with the inlet port 3 of" the burner. When it is desired to fill the tank, to inspect any parts wish to be limited to the exact details of construction shown, but reserve the right to make changes in form, proportions and minor details of construction without departing from the spirit of my invention or sacrificing any of its advantages.
