Application filed October 19, 1911. Serial No. 655,582.

To alt fia/wm 'it may concern Be it known that I, RoBEnT F. COLE, a citizen of the United States, residing at Ysleta, in the county of El Paso, State of Texas, have invented certain new and useful Improvements in Orchard-Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to' which it appel-talus to make and use the same.

My invention relates to new anduseful improvements in orchard heaters and more especially to that type of orchard heaters known as center draft heaters and the object of my invention is to improve the construction and increase the efficiency of orchard heaters of the above described character.

A further object of my invention is the provision of an' orchard heater having a draft flue in which provision is made for the passage of air into the flue from the side of the'heater, thus doing away with the necessity of false 'bottoms and the like which have previously been employed, thus decreasing the co'st of manufacture while at the same time' increasing the efficiency, this latter because of the fact that the draft coming from the side rather than from the bottom permits the heater to be employed equally as Well in shallow water, mud, or sandy soil as upon firm ground.

With these and other objects in view. my invention will be more fully described, illustrated in the accompanying drawings and then specifically pointed out in the claims which form a part of this-application.

In the drawings, Figure l is a front elevation of my improved heater.- Fig. 2 is a section on the line 2-2 of Fig. 1. Fig. 3

' is a section on the line 3&3 of Fig. 2. Fig.

4 is a vtop plan View of the complete device. Fig. 5 is a detail perspective view of a modified form of heater.

Referring more specifically to the drawings, in Which similar reference numerals designate corresponding parts hereof, 10 designates in general the body of my improved orchard heater which as shown, consists of a substantially cylindrical shaped receptacle or pail, preferably formed of sheet metal and open at its upper end. The bottom of this body member is cut away radially as shown at 11 to form a U shaped aperture, while the side is cut away as at 12 to form a V shaped aperture,'the wider end of which forms a continuation of the outer end of the aperture 11.

'lhe chimney or flue of the heater which as a whole, is designated by the numeral 13 is preferably formed from a single piece of sheet metal substantially rectangular in shape and bent longitudinally in such a manner that one end may be secured about the cut away portion 11 of the bottom while its side edges are secured to the free edges of the side of the body member 10 as shown, said parts being secured together `in any preferred manner as by soldering to form oiltight joints. The edge portions of the sides of' this member 13 at the upper end there` of, are drawn together throughout a portion of their length as shown at 14 leaving a circular opening 15 at the top. As will be readily seen the draft flue thus formed extends throughout the height of the heater and is open at its side throughout the greater part of its length, being closed only at a point adjacent its upper' end. The fiue is provided with a plurality of apertures 16 at its upper end as shown to permit the air to ass more freely to the flames.

n operation it will be readily seen that air enters the flue through the sideand because of the converging sides of the flue the air is forced upwardly and inwardly and passed out through the openings 16 and the open end 15 of the fille.

The heater 10 is provided with a cover 17 having a circular opening 18 formed adjacent one edge and a cylindrical casing 19,- also formed of sheet metal, has its upper end passed outwardly through this opening. This easing 19 is cut away at its side to. form a V-shaped opening 2() corresponding in shape and size to the V-shaped opening formed in the side of the heater, this opening permitting the positioning of the casing 19 about the flue as best shown in Fig. 3 of the drawings, with its lower end resting upon the bottom of the heater, said lower end being notched as at 21 to permit the oil to pass from the main body of the heater into the casing and about the flue. For the sake of convenience, the cover is preferably secured to the casing by soldering or other preferred means. As will be seen, the body 1() forms, as a matter of fact, a fuel reservoir for supplying fuel to the burner formed by the casing 19 and the flue, the oil burning only within the casing.

In Fig. 5 of the drawings I have illus trated a slightly modified form of heater in which the size of the body 10 is considerably reduced and in which the casing 19 is omitted as well as' the cover 17. In this form the oil burns in the body of the heater. This latter form is particularly useful in small heaters in which the heat is required only for a short time while the form first described and having the oil reservoir is employed in cases in which the heat lis to be kept up for several hours continuously.

In operation, the heater is filled with oil and placed upon the ground with the opening 12 positioned in the direction from which the wind is blowing. The oil is then ignited within the casing 19 if the first described form of heater is employed, or within the body 10 if the latter form of heater is employed. The air passes into the Aopening formed in the side of the heater to the iiue and upwardly through the same, part of the air passing through the open upper end of the iue and part through the apertures 16. By extending the inlet opening of the flue throughout practically its entire height the supply of air is not only increased but is much less likely to be cut of by the blowing of leaves or other foreign matter against the heater.

As will be readily seen the only difference between the two forms of heaters consists in the provision of a combustion chamber and cover for the larger form.

In operation the heater is filled with the oil or other liquid fuel to be employed and ignited in the customary manner. rIhe burning of the fuel immediately causes the setting up of a draft through the flue, the air passing in through the opening formed in the side of the heater and then upwardly and inwardly as previously described.

As will be readily seen because of the air being supplied from the side of the heater, the heater will be equally as effective when standing in shallow water, lnud or sand, as

when upon rm ground.

What I claim is: 1. An orchard heater, comprising a body tom thereof about the U shaped aperturel and with its side edges secured to the edgesk formed by the V shaped aperture in the side of the body member, the side portions of the upper end of said iue adjacent the body member being brought together and secured to each other.

2. An orchard heater, comprising a body member open at its upper end and provided with communicating apertures in its bottom and side, and a flue positioned within said body member, said flue being formed from a single piece of sheet metal bent centrally to form converging side walls and a tubular upper end, the.edges of the lower end and sides of said flue being vsecured to the edges of the bottom and side of the body member formed by the apertures formed therein.

An orchard heater, comprising a body member open at its upper end and provided with communicating openings in its side and bottom, a flue having converging side walls and a tubular upper end positioned within said body member with its side edges secured to the edges of the side of t-he body member formed by the opening therein, a cover for said body member provided with an aperture, and a casing secured to said cover and extending through said aperture, said casing being open at each end and provided with a longitudinally extending aperture the side edges of which are inclined to correspond with the inclined faces of the flue whereby said casing may be positioned within the body member and about the flue.

In testimony whereof, I affix my signature, in presence of two witnesses.
