ORCHARD HEATER Filed April 21, 1957 Patented July 11, 1939 2,165,279
um'rsn sT 'rss PATENT OFFICE 2,105,219 1 ORCHAR HEATER Howard J. Lambert and Ellis it. Merlflcld, Les Angel's, Cali!" assignors to said Howard Application April :1, 1931, Serial No. 138,145 a mm. (01. 158-91) Our invention relates to orchard heaters and course, that the drawing is illustrative and has for its main object to pr vide means for that the proportions and dimensions. are only burning the smok or causing a more perfect illustrative also and that changes in measurecombustion, whereby to avoid the escape of suich ments, materials and general arrangements can smoke and the products of combustion into the be varied within the scope of our invention. In 5 atmosphere with the attendant evils. some cases the parts or structures are exagger- Many attempts have been made to secure this atcd for clearness.
more perfect combustion, and we have by many In the drawing 5 designates a fuel bowl or long experiments and reconstructions and reservoir with a filling opening at 6, with cap proehanses flnally succeeded in producing an orvided with airinlet openings therethrough, which chard heater with means for consuming all of can be regulated as to the ,sizeof said inlet openthe smoke and products of combustion, and have ings, in the usual and well known manner. This provided such means so that it can be placed over cap is designated I.
the usual fuel bowl now used in many heaters, Mountedpn the neck 5' of said bowl, is a shield or it can be used in connection with any source or member 8, shown of conical form and provided of smoke to prevent i escape into the atmosaround its bottom 9, outside of said neck 5', with phere, openings 9' and in its side is provided with series Among the salient objects or our invention are: of air inlet openings, as l0, said openings being To provide a construction and arrangement 0! formed by striking inwardly a portion of the maparts to receive the smoke or gases and products terial, as at Ill, whereby the material is sheared of combustion from the source 0! production and and an inwardly projecting portion i0 is the by means of retardation, whirling action and result. i mixing of atmospheric air therewith, to cause a Said openings are formed at different angles, complete combustion of such smoke or products as will be better understood from Fig. 3. The of combustion; to provide in connection therelower rowrof openings stand at approximately with asecondary combustion or expansion chamforty-five degree angle relative to the vertical, bar to which andthrough which saidmixture 0! as at II, II. The next upper row stands at apair, gases and products of combustion passes for proximately thirty degrees, as at l2, ii. The further combustion; to provide in connection next row stands at approximately fifteen degrees, with a device of the character referred to an as at i3, i3, and the upper row stands practically $0 overhanging canopy designed to reflect or deflect vertically, as at i4, M. This arrangement ser es the heat downwardly around the structure, to cause the inflowing air to whirl within zhe whereby to maintain a higher temperature in shield 8. and around the structure; and, in general, to Mounted within said shield 8, is an inverted provide a more eflicient means for consuming the dome-like member ii, of material suiliciently as smoke and products of combustion coming from heavy to stand the heat, such as cast iron, or an orchard heater or other device producing the other suitable material, said dome member being same, whereby to eliminate the objectionable feasupported on the bottom of the shield 8 by three tures now common in all orchard heaters, smudge legs, i6, i6. Said dome terminates in a discharge, pots and the like. stem-like portion l5.
In order to fully explain our invention, we have Within said dome-like member l5, stands an i lus a ed One Pr t c e bo t t e e 8- air inlet pipe [1 having a flaring upper end i1 embodied in an orc heater. which We w and surrounded by a sleeve member [8, to form describean air space I! around said pipe ll. Said pipe the drawing we 1 is vertical m H, at its lower end connects with a pipe 20, view through an Orchard Olll mvenwhich is extended t ly and d tion applied thereto Q OllGh Figure 2 is a cross sectional view taken on the the 9 of said Shield as and 8-150 1m e of Fig and provided with a flaring inlet mouth at 2| to direct e air upwardly into said dome i5. nifibifhii fiififi'aiiii its: Meeeeee ee eee ee eee e we eeeee e. through. is an expansion drum 2!, which is shown of larger Referring now in t il to th drawing, we m diameter around its middle portion than at its describe the structure here shownas one embodl- Opposite ends. u s a ly as il ustrated, thou h ment of our invention. It will be understood, at its dimensions can be varied somewhat in actual a use, and as ma be required, according to the general size of the completed structure.
Mounted over the upper end of said drum 22 is a canopy or hood 23, which extends outwardly and downwardly sufliciently to reflect or deflect the heat dow wardly around the is considerably raised by the reflected heat.
A stack, of any suitable height, designated 24 be briefly described as follows:
The oil in the reservoir 5 is ignited through the opening at 1, in the usual manner, with the result that a generation of heated gas rises therefrom. The dome I5 has the restricted outlet or flue 15' which retards the upflow, and the outer in connection with said dome l5 and flue l5 creates a Venturi tube structure, around the top of said dome I5 and said flue l5 for the through the openings 9' in the bottom of said member 8, and the gases which may escape under the edge of said dome member l5, and the air inlet openings l0, H], which pansion drum 22. flected or is directed downwardly around the fuel reservoir 5 and tends to maintain the oil and gases in a heated the gases out at the her I5, so as to pass over the air ports 9' and then upwardly in mixing engagement with the air flowing inwardly through the openings l0.
gases that may have passed through the lower chambers of combustion.
By much experimenting this general construcform and rapid Thus we have provided an orchard heater in which, in addition to the fuel bowl in which the fuel is ignited, there is a primary combustion claims.
We claim:
1. In an oil burning heater, the combination with a bowl for fuel oil having an opening in its top, an inverted bowl-like member over said opening to receive products of combustion and gases from said opening, like extension extending upwardly therefrom,
around the outside of said... bowl-like member within said shield, and a stack structure above said shield and said bowl-like member.
2. Means for burning the smoke and products of combustion which includes a conical shaped outer shield having air and a canopy around said structure for deflecting heat downwardly around said structure.
