PORTABLE STOVE.

Be it knownthat I, CLARENCE O. SHEL- l DON, a citizen of the United States, and a yio lid

supplying heat in orchards to resident of Donna, in the county of Hidalgo and State of Texas, have invented certain new and useful Improvements in lPortable Stoves, of which the following is a speciication.

This invention relates to improvements in portable stoves.

The invention more particularly relates to an oil stove adapted for Out-of-door use for prevent the fruitI from being damaged by frost, or for a similar purpose.

The general object of the invention is to provide a stove of this character which is exceedingly efficient and economical in operation.

It is also an object of the invention that the stove be durable and inexpensive to manufacture.

A further and important object of the invention is that the stove be adapted to continuously operate without attention.

y A still further object of the invention is that parts of the stove subject to deteriora-- tion maybe renewable.

Other objects, and objects relating to details of construction, combination and arrangement of parts will hereinafter appear in the detailed description to follow.

The invention is illustrated by way of o X- ample in the accompanying drawmgs, 1n which Figure 1 is a central vertical sectlonal view of a stove constructed in accordance with the present invention.

Figure 2 isa bottom plan view of tho stove cover.

Referring to the drawings generally R 1ndicates a receptacle or tank in which fuel o1l for the stove may be retained, C mdlcates the cover therefor and C the chlmney.

The receptacle R is preferabl circular 1n cross section 'and tapers towar its bottom and has its upper edge turned outwardly to form a bead 10.

The cover C consists in a frusto-conicalv sheet body portion 11 which is provided with a suitable opening'at its upper end to receive a nipple' 12, said nipple having a lip 13 formed upon its lower end by which the same may be secured to the cover C. Preferably the lip 13 of the n1pple should to telescope 1922. serial No. 558,043.

be welded to the cover C. The lower peripheral edge of the cover is bent or crimped upon itself to provide the flange extension 14 of double thickness as shown and to provide the downwardly depending skirt or lip 15 which is adapted to be received by the upper end of the receptacle R and the flange 14 adapted to seat upon the bead 10 of the receptacle R whereby to removably support the cover C in an eilicient manner. The c himney C comprises the two casting sections 16 and 17 and .the sheet metal section 18. The casting 16 consists of'a cylindrical lower end portion 19 which is adapted the nipple 12 extending from the cover C and a perforated bowl-shaped portion' 20 which terminates at its upper end 1n a cylindrical portion 21 and said cylindrical portion having formed about its lower end a supporting flange 22.

The cylindrical portion 21 is adapted to be telescoped by the sheet metal section 18 and said sheet metal section 18 being supported against downward movement by the fiange 22. The casting 17 consists in a body portion 24 which tapers toward its upper end and which terminates at its lower end in a cylindrical extension 25 which is adapted to telescope the upper end of the section 18. The upper end of the body portion 24 of the casting 17 terminates in a reduced cylindrical portion 26 and which may be telescoped by ordinary stove piping or the like in or der to extend the chimney as indicated at 27. Also when the stove is not in use there is provided a closure for the upper end of the casting 17 which consists in a cap indicated 'by dotted lines at 28.

Within the receptacle R there depends a skirt S, said skirt being semi-circular in cross section and tapering toward its lower end and being secured at its upper end to the body portion of the cover C by the means of rivets or the like as indicated at 29. The longitudinal edges of the skirt are in spaced relation with the side wall of the receptacle as indicated at. 3() and the lower end of the skirtvis in spaced" relation with the bottom of the receptacle as indicated at 31. Upon the body portion of the cover at a point registering with the enclosure formed by the skirt S there is hinged a flap door D, said door consisting in an annular member 32 which has its inner periphery formed with a groove adapted for enclosing l no y a circular plate 33. The plate 33 carries a handle 34 and said plate together with the body portion 11 of the cover are formed with openings as illustrated whereby entrance of air into thereceptacle R may be effected. The amount of air' may be closely regulated by manipulating the plate 33. Theannular member 32 is hinged to the body portion 11 of the cover as at 35 and adapted to be swung upwardly and thus to serve as an opening for filling the receptacle with fuel oil.

From the inner side of the body portion 11 of cover C -there projects a plurality of studs or pins 36 which are arranged in circular formation and adapted to support a baille plate or divisional plate P against upward or downward movement through the cooperating lugs or hooks 37. The plate P may be easily removed or positioned in an obvious manner. Diametrically opposite to the skirt S, the pflate has aI peripheral portion or a segment cut therefrom to provide .la passageway 37. l

In the use of the present stove, the receptacle R is filled with oil to a suitable level, and if this oil is heavy such as crude oil or the like, then the pla-te P should be removed. Now a small quantity of gasoline may be poured through the opening adorded bythe door D and upon the oil within the enclosure afforded bv the skirt S. Upon igniting this gasoline, the llames thereof will pass around the longitudinal edges of the skirt S and during this passage will be, substantially smothered. The hot gases generated by this flame quickly carry the fumes arising from the oil within the receptacle upwardly and through the nipple 12 or outlet passage of the cover C. Immediately upon these fumes passing into 4the upper end of the casting 16 air rushes in through the perforated portion 20 of this casting and supplies the oxygen necessary for combustion ,of the fumes. At this point slight explosions will take place and the section 18 of the chimney will become highly heated. The inrush of air through the perforated portion 20 of the casting 16 prevents any clogging of the perforations of this portion. Also the explosions which occur in the upper end of the casting or within the section' 18 further eliminate any possibility of clogging of this perforated portion of the 'cast. ing'16. vWhen starting the stove it is necessary to apply a torch or light to the perforated portion 20 of the casting 16 in order that'ignition of the fumes may be had. After the stove .is once started the same will operate continuously and without undue ex- 4plosions to lift the oil from the receptacle R.

When it is desired to use coal oil as a liquid fuel or other similar distillate, the plate P is placed in its position and with this ercomprisin rangement the fumes passing from the enclosure afforded by the skirt S- must pass beneath the plate P until they reach the passageway' 37 afforded thereby before they may escape from the cover C. This further insures to smother the flame maintained within the enclosure afforded by the skirt D. In other words, this flame must not be permitted to continue and pass out through the cover C, for the reason that under these conditions the stove would unduly smoke and operate at a very low efficiency.

It is believed from the construction shown of the chimney C thatl it becomes obvious 'that the section 18 is easily removable. The castings 16 and 17 are not subjected to great Aheat like the sheet metal section 18 and need not be renewed. The stove-pipe 27 may be of any length desired. Also the chimney construction, Aas shown, is-weather proof and by placing the cap' 28 over the upper end of casting 17. the stove may be permitted to remain in the fields for any period of time without harm thereto. Furthermore with this arrangement the stove may be filled with oil and prepared ready for operation at any moments notice, that is, made readyfby removal of the cap 28 and placing the stove-pipe extension 27 upon the upper end of the casting 17.

While I have shown and described, the preferred form of my invention, I'wish it to be understood that I am aware of the fact that the construction, combination and arrangement of parts may be changed by those skilled in the art without departing from the spirit of the invention as indicated by the appended claims.
