HEATER.

Specification of Letters Patent. Pate t d pl 16 1922 Application filed December 8, 1919. Serial No. 343,302.

ing soldering irons, curling irons and other articles, and more particularly to such devices wherein alcohol is employed as the fuel. The invention is directed especially to a device to be used in conjunction with a solid alcohol fuel of which Sterno canned heat is an example.

The objects of the invention are to provide a device wherein the intensity of the flame of the burning fuel will be increased.

. A further object is to provide a device in which the flame will be concentrated on the article to be heated.

Another object is to provide a device which will act as a support for the article to be heated, and to art as a wind shield.

These and further objects will more fully appear in the following specification and accompanying drawings considered or separately.

One embodiment of the invention is illustrated in the accompanying drawings in which like parts in all of the several fi ures are designated by similar characters 0 reference, and in which Fig. 1 is a longitudinal section of the preferred embodiment of my invention, taken on the line indicated by 1-1 of Fig. 3.

Fig. 2 is a front elevation of the heater.

Fig.3 is a top plan view of the heater partly in section, the section being taken on the line 3-3 of Fig. 1.

In the embodiment of the invention illustrated, the invention is illustrated in conjunction with a can or receptacle 1 adapted to contain a solidified alcohol fuel. As shown the can 1 may rest within a base 2 which may be rested upon the ground or other support 3.

The fuel. receptacle may be of any desired dimensions or configuration, that illustrated being a cylindrical can having an annular member 1 carried at one end thereof and provided with a circular flame opening therein. In the embodiment illustrated the flame opening is defined by a depending, circular flange 5 on the member 4 and adapted together opening 7. The lower to form the seat for a friction cover (not shown) as is common.

The heater of this invention preferably comprises a hollow body of thin sheet metal 6 o cylindrical form. The upper or top wall of the body is provided with a draft portion of the body is contracted to form a throat 8 which may be of approximately the same area and shape as the draft opening 7 Below the throat 8 the material of the heater is formed to a flat horizontal wall 9 of annular form, the outer edge of which extends downward to form a short cylindrical wall 10 which is provided with a series of perforations 11. An annular flange 12 extends outward from the lower edge of the wall 10, and a depending cylindrical skirt 1.3 extends downward from the outer peripheral edge of the last mentioned wall. A series of perforations 14. is formed in the material of the heater preferably at the junction of the flange 12 and the skirt 13.

The area and configuration of the opening defined by the skirt 13 is such that the lower edge of the shirt may rest upon the member ll-between upper edge of the wall of the can 1 and the flame opening 5 and encircling the latter whereby the flame issuing from the opening will be directed upward through the throat 8 into the body 6.

In the vertical wall of the body 6 is formed an opening 15 which may, as shown, he of rectangular shape and of a size sufficient to permit of the entrance of the head 16 of a soldering iron, or other article to be heated. At the lower edge of. the opening 15 a notch 17 is provided, which may conveniently be of triangular shape as shown. When a soldering iron is to be heated in the device the tang or shank 18 thereof will rest within the notch and be prevented from movement relatively to the body. The handle 19 of the soldering iron, when the latter is in position to be heated, may rest upon the support 3.

The notch 17 is of triangular or wedge shape in order that bodies or implements of different diameters may rest therein, and the wedge shape of the notch will further act to retain the implement in position by the wedging action of the tang in the notch.

The air entering the perforations 11 and 14 will supply the oxygen necessary to support combustion and will be directed against thereof, but it is to be understood that the the axial center "plied as shown in Fig. 1.

r and 14; Y will support part not consumed be directed upward in a to: remain in the v handle 19 resting on the support will act as a prop to in the support, and means for support for the body,

the flame in such a manner that the latter will be formed into a cylindrical column in ofthe body 6. This action of theair entering the perforations 11' and 14 will be supplemented by the relative dispositions of the throat and draft openings. The base 3 is for the purpose of stabilizing thecaniand heater, but it is obvious that the same may be dispensed with if desired.

The operation is as follows y The fuel 20 is, ignited and the heater ap- The head of a soldering iron, for example, is inserted through the'opening 15 with its tang 18 engaging the notch resting on the support 3.

17 and its outer extremity The air drawn in through the openings 11 combustion and that hollow vertical column and confine the flame into a 1 vertical cylindrical column. The shape :of the throat will further confine the flameland direct it upward toward the draft opening 7.. The iron 16 will be positioned directly in the column of. the flame and at the point of greatest heat intensity.

The shape of the notch will cause the iron desired position and the prevent upsetting of the can and heater. 7 i

' In accordance with the provisions of the patent statutes, the

principle of the inven .tion has been described together with what is now considered to be the best embodiment apparatus shown is merely illustrative and the invention may be carried out in other ways.

Having nowdeseribed the invention, what is claimed as new and desired to be secured by Letters Patent is'as follows 1. A heater comprising a hollow body and an integral portion forming a support for the body, there being a contraction between the body and support and forming a throat, a draft opening in the body in alinement with the throat, there being draft openings gripping and supporting anarticle to be heated within the body, and between the throat and the alincd draft opening.-

42. A heater comprising a hollow body, a

there being a contracted portion between the body and sup port and forming a throat, there being a draft opening in the body in alinement with article,

in the body insertion of an the throat, there being draft openings in the support, there being an opening in the body for the insertion of an article to be heated, there being an open notch in a wall of said opening adapted to receive a portion of said said article being positioned in the opening by engagement thereof with the side walls of the notch.

3. A heater comprising a hollow body, a support for the body, there being a contracted portion between the body and support and forming a throat, a d aft opening in the body in alineinent with the throat, there being an opening in the body for the insertion of an article to be heated, there be ing a tapered notch in a wall of said opcning adapted to receive a portion of said article, there being draft openings in the support, and means for supporting the article to be heated within the body and between the throat and the alineddraft opening.

4. A heater comprising a hollow body. a support for the body, there being a contracted portion between the body and support and forming a throat, a draft opening in alinenient with the throat. there being an opening in the body for the article to be heated. said opening being perpendicular to the throat and alined draft opening. there being a tapered notch in a wall of said opening adapted to receive a portion of said article, there being draft. openings in the support, said notch being the only means carried by the body for supportin the article.

5. A. heater comprising a rece .)taclc adapted to contain fuel. an annular member forming the top of the receptacle, a hollow element resting on the member and in communication with the receptacle, said element comprising a body, there being a contraction between the receptacle and body forming a throat, there being a draft opening in the body in alinement with the throat. draft openings in the element between the receptacle and the throat, there being an entrance in the body between the throat and the ,alined draft opening. one side of said en- GEORGE STANLEY MEIKLE. itnesses A.
