FUEL OIL STOVE Clarence B. Heroux and John F. Wetzel,

"Application December 7, 1949, Serial No. 131,682 H v 3 Claims.

This invention relates to stoves, and more particularly to improvements in stoves for burning hydrocarbon fuels.

An'object of the invention is to provide an improved fuel oil stove wherein a hydrocarbon li'quidis-utili'zed as fuel, the construction of the burner portion of the stove being such that the liquid is vaporized and the vapors, rather than the fuel in liquid form, areburned, which makes for greater heating efficiency.

A further objectof this invention is to provide a fuel oil stove that is, exceedingly light in weight, compact in design, and easy to transport so that'it is ideally useful'for camping or emergency use.

Other features of the invention include means for making the stove very convenient to use in respect to filling, lighting, cleaning and transporting. The ease or convenience of lighting and cleaning is brought about by the provision of a large access opening selectively closed by a door whereby the user is enabled to place his hand within the burner portion of the stove. Still further objects reside in the provision of a fuel oil stove that is strong, durable, highly efllcient in operation, simple in construction and design, easily constructed from sheet metal which may be pressed or folded as desired, easy to manufacture, quite pleasing in appearance and relatively inexpensive.

These, together with the various ancillary objects of the invention which will become apparent as the following description proceeds, are attained by this fuel oil stove, a preferred embodiment of which has been illustrated, by way of example only, in the accompanying drawings, wherein:

Figure l is a perspective view of the fuel oil stove comprising the present invention, parts thereof being broken away to show other parts in greater detail.

Figure 2 is a vertical sectional view as taken along line 2-2 in Figure 1; and,

Figure 3 is a horizontal sectional view as taken along line 3-3 in Figure 2. 7

With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, reference numeral I0 is used to generally designate the fuel oil stove comprising the present invention. The stove consists of several main elements, one of which comprises a burner portion l2. vention include a'heat conserving section M in interior communication with the burner l2, and

a fuel supply tank It.

, 2 The stove is supported by a pair of substa'n' tially channel-shaped legs l8 and 2fl -which are secured by flanges 22 to the burner section 12. The flanges 22 are preferably riveted, but may be otherwise secured. I

Bymeans of straps 24 riveted to theboiler section 12 a fire wall 26 is secured in spaced relationship to the boiler section I2. The'fire wall 26 has formed integral therewith a base plate 28 has an opening 30 therein for a purpose to be henceforth explained. Furthermore, the base plate 28 has integrally formed therewith a flange 32 which is riveted as at 34 to a standard or leg 36 which is riveted atitsupper end, as at 38, to the: heat conserving section. The gas tank I6 is positioned between'the'fire wall 26 andthe standard 36 in friction' 'eng'age+" ment'therewith. A threaded plug 40 .isprovided to selectively close a fuel inlet opening in a corher of the fuel tank. The fuel tank 26"may be readily emplaced upon the base plate 28' with the outlet 42 extending through the opening 30. A needle valve for fuel control which is indicated by the reference numeral 44 is positioned so as to limit the flow of fuel through the conduit 46 to the inlet 48 into the burner. About the inlet 48 is emplaced an asbestos wick 50 in the shape of a torus or cylindrical ring.

The burner I2 is provided with a series of spaced apertures 52 through its lower portions. Additionally, a substantially conical baffle plate 54 having an opening in the top thereof is provided to properly control the flame within the A substantial opening 54 is formed in the lower portions of the burner for allowing access to the interior thereof. Riveted or welded about. the apertures 52 in the burner l2 and spaced therefrom are shields 56mm 56 which have retainers 60 welded thereto for sliding engagement with door .62 which is placed therebetween to cover the opening 54.

The fire wall 26 has formed at its upper end a flange 64 for supportingly engaging the bottom portion of the heat saver I 4. A vent 66 is provided in the upper portion of the heat saver for connection with a suitable flue for allowing the excess gases or combustion to escape.

The operation of the fuel oil stove is quite simple. The door 62 .is opened allowing access through opening 54 in the burner. Turning the valve 44 will allow fuel to flow into the bottom Other important portions of the inof the burner l2. This may then be ignited by hand and the heat produced is almost spontaneous. For a few minutes the flame will burn yellow, but as the metal of the burner heats, agas is formed from the inflowing fuel. As this rises it mixes with the air from the holes about the sides of the burner designated by the reference numeral'52, giving an intense blue flame. The heat is regulated by opening or closing the fuel valve. The fuel supply in the tank [6 is guarded by the fire Wall 26 which forms a shield. However, enough heat is generated to allow the fuel from the tank l61toflow freely through the needle valve 44;" The shields 56 and 58 will prevent the light formed during the combustion of the fuel to emit from the stove to any great intensity. Furthermore, the guard will not prevent the proper and automatic draft which is needed to keep the proper combustion maintained in the burner.

The asbestos wick 50 is placed about the fuel inlet 48 to help in the lighting of the fuel. and also to maintain the flame with the smallest amount of fuel. The tank I6 is shielded fromthe heat conserving sectionl by the large air gap therebetweeny However, this air gapserves a further function; in order to carry thedevice, one may merely slip has hand in between the heat saver l4 and the-tank l6 and lift up on the standard 36 as atthe portion thereof designated byreference numeral 68. The top surface of "the heat conserver is thus designed to get hot enough for cooking'thereon and thus the device isespecially adaptable for a campers cooking :st'ove, besides supplyingheat at thecamping location.

Since from the foregoing, the construction and advantages of this fuel oil stove are readily ap parent. further description is believed to beunnecessary. i

Having thus described the invention, what is claimed as new is:

1. A portable stove comprising a vertical casin having a fuel burner therein, a horizontal casing secured to the upper end of the vertical casing and communicating therewithto form a combustion products discharge passage thereior, a fuel tank unde'rlying' 'said horizontalcasing, a fuel conduit connecting said 'fuel tank and burner,

flow control means for said conduit, a vertical leg supporting the end of the horizontal casing that secured to and supporting said horizontal casing However,- .since numerous modifications .will

readily appear to those skilled in the art after a consideration of theforegoing specification and accompanying drawings; it is not intended to limit the' invention to *the' precise embodiment shown anddescribed,v but all suitable modifications and equivalents may be resorted to which fall within 4 the scope of the appended claims.

and at its lower end having a horizontal portion supporting said tank and secured to and carried by said vertical leg. I

2. .The combination of claim 1 including lateral bracesrigidly connected to said vertical casing and to said vertical wall.

3. The combination. of claim .1 wherein said vertical casing has air openings therein, shields rigidly secured to saidvertical casing and said vertical wall and surrounding said air openingsin spaced relation thereto. v I
