. iPatented Dec.l 5, 1911.v

To'all whom it may concern:

Be it known that I, WILLIAM HOWARD SMITH, a citizen of the United States, i'esiding in Atlanta, in the county of Fulton and State of Georgia, have invented a newV and useful Improvement in Orchard-Heaters, of which the following is a specification.

My invention relates to improvements in orchard heaters. f

.The object of my invention is toprovide an orchard heater'of a simple, efficient and durable construction capable of being manufactured and furnished at small cost, and

which may be easily and quickly assembled,

filled with fuelA and lighted.

My invention consists in the means I. em-

ploy to practically accomplish this object or result as herein shown and described and more particularly specified in the claims; the same comprising in coperative combination a sheet metal pot or liquid fuel container having an external roll at its upper 4end; an annular sheet metal top secured thereto 5 a perforated sheet metal chimne or flue member coiled or curved into cylindrical shape with its meeting edges overlapping and fit-V ting within the opening of the annular top and resting atits lower end on the ybottom of the pot or fuel container; a corrugated sheet metal hood of frusto-conical shape, having an inwardly projecting annular iiange at its upper end surrounding the upper end of the chimney lor iue member, and

with the inner walls of its corrugations at the lower end surrounding and, wedgingly engaging the upper end 4of the pot or fuel container and its annular top secured thereto, to form a seriesof air passages distributed uniformly around the whole circumference of the pot or fuel container at the upper end thereof.` The annular top is made ofa square piece of sheet metalA the side of ing openings for air passages between the 'annular top and the upper rim of the con-.-

tainer. A cover, preferably of a square piece of sheet metal with itscorners turned atan angle to fit in and engage corrugations of y the hood, is provided to cover the hoo-d and, iue ofthe heater when the heater is notl in luse and exclu'derain. "f

My invention also consists the novel lconstructions of parts and devices andin the novel combinations of parts -and devices lherein shown and described and more particularly specified in the claims..

`In the accompanying drawing forming apart offthis specificationFigure l is aside 60 elevation of an orchardheater or pot embodying my invention. Fig. 2 is a central .vertical longitudinal section on line'2-2 of Fig; 1. '.Figs. 3 and 4 are horizontal sections on lines 3 3 land 4 4 respectively of Fig. 2. I6.5

vIn the-drawing 1 represents the body of a sheet met-al fuel pot or container preferably -of frusto-conical form with its llargervend uppermost and made like the other parts of ordinary black sheet iron or steel. The body has one 0rmore lock side seams 2 at the meeting edges of the blank or blanks from which it is formed andthe bottom 3 is secured to the lower endof the body l by a double Vseam 4 so that all the seams of the 75 vessel -will beliquid tight for `holding crude petroleum. or other like liquid or semi-liquid fuel and adapted to withstand the heat and re.- At its upper end the body of the vessel is provided with an external rolled rim 80 5 which embraces a stiffening wire 6.'-

The annular .top 7 has a large central opening 8 to receive thechimney or flue member 9 andy it is preferablyfurnished with segmental flanges 10 turned under the 85 external rolled rim '5 of the container to secure the annular topY thereto while leaving Vopenings or air passagesll between the'annular top and the rim of the-container at the four rectangular sidesV of thel annular .topfthe segmental curved -ianges 10 being formed at the diagonal rounded portions of the square sheet from which the annular top is formed.

AThe chimney or flue 9 is furnished with 95 y curving-a rectangular piece of perforated lollsheetlmetal into cylindrical form, its meeting edges 13, '14;being`loose or unconnected but overlapping. each other. l

orflue member 49 is open at bot-h ends and The chimney tits ,removablywithin` the central opening of the'ann'ular top 'and rests at its lower end -agrinst the bottom?) of the fuel containerl.

` lower end of the hood, the corrugations beingmaterially deeper at the lower end of the hood than at the upperend thereof. The i inner .walls 17 of the corrugations 16 wedgingly engage the rim 5 of the container 1 I 'and-segmental flanges 10 of the annular top j which may be partly. removed to regulatewhich. embraces therolled rim of the contain'r for aportionof lits circumference.

' This wedging engagement between the lower end of the corrugated hood and theupper end of the containerl serves to securelyhold the hood 15 in. place on the container. The externally projecting walls 18 of the series of corrugations 16, form a series of air passages or openingsbetween the rim of the container 1 and the hood to admit air into.

thecontainer through'the openings 11 between the to 7 and container 1 and through the perforatlons 12' in the Hue 9, which are .both above and below the annular top 7, to suport combustion of ,the fuel inthe container and create a proper draft in the flue 9. The'corrugated hood 15 is provided at its upper end withan inwardly projecting annular flange 19which surrounds the upper end' of the cylindrical chimney lor Hue mem ber 9.' The4 hood is also provided with an upwardlyprojecting annular head2() at the with the annular horizontally extending ange 19. As the corrugated hoodhas a tight .wedging engagement at its lower end with the u per end or lrim of the fuel coniiood will beheld firmly' in posi tion.. :.1

The cover 21 which covers the upperV e of the' flue or chimney' piece-'.9 andfof the hood 15 when the `vessel is not in .use or combustion as desired, may be of any suitable form, such for example as a flat piece of metal, 'a round disk with a'depending an.-

nular flange or a rectangular piece of metal with its corne'rsQE)J turned at an angle to engage the corrugations 16 of the hoodA 15:

In operationV the body or container 1 is 4filled with-crude petroleumor other cheap liquid or semi-liquid fuel and then ignited, preferably by'a torch orgby. putting al small quantity of waste or-other fibrous material in the container-5 through the flue. The air to 'support'combustion enters under thehooc -and passes in part beneath the topj-platf through the openings l1 between `its sid'f edges. and the rim of the container anel thence passes 'through the holes orperforations in the iue'member into the flue chamber, combustion being confined or 'chie'iy eonlinedto the' surface of the oil insidevthe flue. As the oil in the container is conenmed,A further holes inthe opening are exings betwe'eii its side edges and the rim of the container, andl provided with a central opening, a perforated flue sheet 'rolled into a cylindrical form with loosely overlapping edges, and fitting within the central opening of said top plate, and resting at its lower end on the bottom of the container, and a frustc Iconical longitudinally corrugated hood with the inner walls -of'its corrugations. 'wedgingly engaging the outer rim of the con- 'tainer top plate, the outer walls of its corrugations forming a series of air passages distributed entirely around the circumference'of the container, said hood having an inwardly projecting annularflang'e at its upper-end surrounding the upper end of the Hue, said flange ofthe hood being substantially flush-:with the upper end of theflue -with an annular air passage therebetween junction of the longitudinal corrugations 16"- Aupper end of theflue and a commoncover plate adapted to close both the upper end oil the hood and the upper end of the. flue, said cover having downwardly bent and circumferentially-arranged engaging fingers, subtanially as specified.

An orchard heater,4 comprising in combination a sheet metal fuel container having -an externally rolled rim at its upperl end, a

top plate secured thereto and having openings between its side edges and the rim oi the container, and provided with afcentral opening, a perforated flue sheet rolled intc cylindrical form withloosely overlapping edges, and fitting within the central opening of said top plate, andresting at its lower end -on the bottom'of the container,l and a frustc conical longitudinally corrugated hood with the inner walls of its corrugations 'wedgingly engagingthe outer rim of the container top plate; the outer walls of its corrugations forming a series of air passages distributed entirely around the circumference' of the deflect air inwardly from the 'upper end of ontainer, said 1hoog having inwardly the iu'e,l substantially as specified. projecting annu ar 'ange at itsup er end surrounding the upper end of the filgie, seid WILLIAM HQWARD SMITH' v5 fiange ofthe hood being substantiallyiiush Witnesses:
