COIVIBINED HEATER AND RADIATOR.

Specification of Letters Patent.

Patented Sept. 27, 1910.

Application filed. February 3, 1909. Serial No. 475,752.

To all whom it may concern:

Be it known that I, ELAM V. Bnn'rnnr, a citizen of the United States, and 'a resident of Everett, in the county of Snohomish and State of Washington, have invented a new and Improved Combined Heater and Radiator, of which the following is a full, clear, and exact description.

The purpose of this invention is to provide novel details of construction for a heat radiating stove that may be readily converted into a cooking stove, the device being well adapted for consuming liquid fuel or coal by slight changes in construction.

The invention consists in the novel construction and combination of parts, as hereinafter described and defined in the appended claim.

Reference is to be had to the accompanying drawings forming a part of this speciti cation, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the device. arranged a heat radiator; Fig. is a sectional side view, taken through the longitudinal center of the heat radiator shown in Fig. 1; and Fig. 3 is a transverse sectional view, substantially on the line 33 in Fig. 2.

In carrying into effect the features of the invention, any available material may be utilized, and the shape thereof may be considerably modified within the scope of the invention. In the example here presented, plate metal is employed, which is preferably cut and bent into form as represented in the drawings, which will now be described.

The preferred fuel for the evoluton of heat, is liquid, such as kerosene, gasolene or alcohol, which may be consumed in a suitable burner fed by a wick, that is supplied with said combustible from a reservoir.

In the drawings, 10 indicates a liquid holder, that is cylindrical and may be of any preferred dimensions, said holder or tank having a filler orifice in its upper side, normally closed with a screw cap a or equivalent means.

There are a plurality of burner tubes b projected from the upper side of the tank 10, that contain wicking c, as indicated in Fig. 3, said tubes being spaced from each other; and as represented, the wicks may be adjusted in the usual manner by thumb wheels (Z on the ends of shafts d that enter the side of the tank, and as this is a common means for regulating the height of the wicks, it is not considered necessary to further illustrate this minor detail.

The tank 10 is supported concentrically within a cylindrical wall 11, which is the base section of the combined heater and radiator. Upon the upper edge of the base section 11, a top wall 12 therefor detach ably mounted and removably secured by means of a depending peripheral flange 12, that is secured upon the edge of the top wall and fits loosely upon the exterior surface of the base section when the top wall is mounted thereon. Centrally in the top wall 12, acircular opening is formed wherein is fitted and secured the lower edge of a deflector cone 1%, that projects upward through said opening. 'lhere is an upwardly projecting peripheral flange 0 formed on the edge of the top wall 12, and may be integral with the flange 12, said flange 6 serving to hold in place a coacting second section that is constructed as follows.

A plate metal coniform wall 13, that at its lower end is provided with an imvardly turned flange, has such a relative diameter at said lower end as adapts it to lit loosely within the upturned peripheral flange 0 when the flange on the wall 13 is seated upon the top wall 12. It will be seen in Fig. 2 that there is an annular space or channel it formed between the central cone 12 and the coniform wall 13, when the latter is in position 011 the top wall 12; and furthermore, that the burners Z) are so relatively positioned that flame therefrom will impinge upon the inner surface of the coniform wall 13 and spread thereover and quickly heat said wall, that converges the annular heat current as it passes upward.

Cooperative with the base section 11 and coniform section 13, is a third section, comprising the following details: Upon the lower edge of an inverted coniform wall 14'. that is formed of plate metal, is allixed the upper edge of a circular downwardly flaring wall 143, these firmly connected walls being held so as to give the lowermost wall ll a central position in the annular space 72, by angular braces i, that are respectively secured upon the inverted coniform wall l l near its lower end and the upper portion of the coniform section 13, as is indicated in Fig. l.

A downwardly converging deflector cone 15, is centrally and vertically supported and positions given to the secured in the inverted coniform wall let, by an impingement of its lower end as at m, upon the apex of the deflector cone 12 and securing U-shaped braces 71 between the in verted coniform wall 1a and the deflector cone 15 near their upper ends. The upper end of the deflector cone 15 may be closed, as shown at 15*, and on said top wall a handle piece 0 is secured, which affords means for placing the third section in position on the top wall 12 or removing it therefrom.

It will be noted in Fig. 2 that the relative opposed deflector cones 12 and 15, and the coniform walls 1% and 1% that have a common axis, when the third section is in position on the top wall 12, affords an annular centrally converged air passage 7) between the cones and concentric walls 14, lt which passage extends from the top wall 15" to the lower end of the flaring wall 14-, which end is spaced from the top wall 12 so as to permit an air passage 1' therebetween.

In the operation of the apparatus hereinbefore described, assuming that liquid fuel in suliicient amount has been placed in the tank 10 and the wicks c are lighted, the flame therefrom will impinge upon the inner surface of the coniform wall 13 and trend upward through the annular channel /2, the evolved heat current enveloping the outer surface of the depending converged wall lat. This heat current will create a partial vacuum ,in the inner annular air passage 2), which wilf induce a downward air current therethrough, this air current becoming highly heated by its intimate contact with the flames from the wicks c, and it will be noted that the rarefied and hot air that impinges upon the wall 141, will be deflected therefrom into surrounding space and warm the air therein.

It is claimed that the details of construc tion for a combined heater and radiator herein set forth, are cooperative and aflord a compact, inexpensive, and practical apparatus for the purpose specified.

It will be evident from the description, that applicants radiating means comprises a pair of spaced concentric frusto conical rings, a second pair of spaced concentric frusto conical rings arranged above the first named rings and with their apexes down ward, the outermost ring being provided with a petticoat extending between the first named rings.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

In combination, a liquid fuel supply tank, burners thereon, a casing surrounding the tank, a top wall on the casing having an upright peripheral flange thereon, and also having a central conical deflector, an inverted conical deflector vertically supported on the apex of the first-mentioned conical deflector, an upwardly converged coniform wall, a downwardly converged coniform wall mount-ed upon the first-mentioned wall and secured to the inverted conical deflector, said converged walls being spaced from the cone deflectors and afl'ording an annular air passage therebetween, and an upwardly converged coniform wall seated upon the top wall of the casing and spaced from the first named upwardly converged coniform wall, affording a conduit for the heat current from the burners, which current envelops and heats the upper inverted coniform wall, from which the heat is radiated.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ELAM V. BENTLEY.
