sMoKnLnss ORCHARD-HEATER.

Specification of Letters Patent.

Patented Sept. 2, 1913.

Application filed April 2, 1913. Serial No. 760,038.

To all whom it may concern Be it known that I, Summon: MoomnA, a subject of the Emperor of Japan, residing at Upland, in the county of San Bernardino and State of California, have invented a new and useful Smokeless Orchard-Heater, of which the following is a specification.

This invention relates to a heater especially designed for protecting orchards from frost, and the main object of the invention is to provide a heater for this purpose which will burn a suitable fuel, such as petroleum distillate, in an eflicient and economical manner without the production of smoke.

Other objects of the invention will appear hereinafter.

The accompanying drawings illustrate the invention, and referring thereto: Figure 1 is a vertical section of the heater. Fig. 2 is a section on line aF-m" in Fig. 1. Fig. 3 is a horizontal section on line m -w' in Fig. 1.

The heater comprises atank or pot 1 which may be of any suitable form, but is preferably rectangular in horizontal cross section, and is provided with upwardly flaring walls 2. A cover or top member 3 rests on top of the tank 1 and is provided with downturned flanges 4: .for engaging with the upper edges of the tank 1 to retain the cover member in position, said cover member being preferably provided with a handle 5 to enable it to be removed from and put into position. Tank 1 is provided with a series of holes or air inlets 7 in each of two sides of said tank, and a closure member is provided for said holes consisting of a slide 8, .guidedin guideways 9 on the side of the tank, said slide being provided with holes 7 adapted to re ister with'the holes 7 in the side of the tan A stack 10 is provided within the tank, the bottom of said stack resting on the bottom of the tank and said stack extending up through the cover member 3 some distance above the top of the tank. Said stack is provided with openings 12 at its lower edge for allowing passage of oil or fuel and with several series of openings 13 at different heights in the stack for passage of fuel and vapor, and with an upper series of openings vapor only. Said stac 10 is preferably of sheet metal, the openings 13 being formed by stamping out the metal, the metal being left attached at the upper edges of said openings and being bent inwardly to form 15 for passage of' deflectors or battle plates or projections 14. Above the cover member 3 the stack 10 is provided with a series of openings 16 for admission of air, this series of openings be ing regulated by a closure member 17 in the form of a sleeve adapted to slide frictionally on the stack 10 so as to be retained in any desired position thereon, the upper end of this sleeve being adapted to extend above the top of the stack to form a continuation thereof.

The operation is as follows: Suitable fuel, such as petroleum distillate, is placed in the tank 1, the stack 10 and cover 3 are put in position and the fire is started by igniting gasolene or other readily combustible material within the tank or within the stack. The slide 8 is opened sufliciently to allow air to pass into the tank in suflicient amount for partial combustion of the fuel and the resulting vapor passes into the stack through the openings 13 and 15, being obstructed in its passage upwardly into the stack by the deflector means 14, so as to insure a more effective mixture of the vapor and incoming air and prevent flames from reaching directly' from the bottom of the stack to the top thereof. To more effectively secure this battling action, the projections or deflectors 14 are staggered or arranged in different angular positions so that the upper series of deflectors extend above the spaces between the deflectors of the lower series. The vapor passing upwardly in the stack receives additional air through the air inlet openings 16 in the stack which are opened more or less, according to requirements by suitable adjustment of the regulating sleeve 17, the amount of air so supplied being regulated to produce a mixture of vapor and air which burns at the top of the stack in a substantially smokeless flame. If more air is required at any time, it can be procured by raising the regulating sleeve 17 and a greater or more efiective generation of vapor may be secured by opening the slide 8 to a greater extent so as to admit more air through the perforations 7 and 7 to the interior of the tank constituting the generating chamber.

What I claim is:

1. A tank having a closed cover and pro vided with air inlet openings, a stack resting on the bottom of the tank and extending upwardly through said cover, said stack having openings at its bottom for passage of ings for passage of vapor, and deflectors ex- ..tending inwardly above said last named openings.

2. A tank having a closed cover and pro--.

vided with air inlet openings, a stack resting on the bottom of the tank and extending upwardly through said cover, said stack having openings at its bottom for passage of fuel, and openings above said bottom openings for passage of vapor, deflectors extending inwardly above said last named openings, said stack being provided with perforations above the level of said cover and a regulating sleeve surrounding said 15 stack and frictionally engagingthe same to regulably close said perforations. o In testimony whereof, I have hereunto set my hand at Los Angeles, California this 2nd day of April 1913.

SUEKIOHI MOGHIDA. In presence of ARTHUR P. KNIGHT, MARTHA M. LANGE.
