UNITED STATES PETER REINHARDT, OF ST. PAUL, MINNESOTA.

COMBINATION HEATER Application led October 8, 1920.

To aZ whom t may concern.'

Be it known that I, PETER REINHARDT, a citizen of the United States, Vresidino at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Combination Heaters and Cookers, of which the following is a. specification.

This invention relates to gas heaters, and more particularly to the small portable type usually adapted to be connected with a source of gas supply such as the ordinary jet, by means of a flexible tube, not shown.

An object of my invention is to provide, in a heater of the class described, improved means, whereby a portion of the heated air is caused to be intercepted and discharged at a particular position on the heater, where lsmall utensils may be so placed as to become heated by the air as it rises from the discharge openings, for the purpose of cooking food or heating water and the like.

'A further object of the invention is to provide a heater of the class described, which is of simple, cheap construction, serving s1- multaneously as a heater, and cooking stove, the parts being arranged so as to effect two separate constantly active hot air discharges, when is use.

To this end, the invention consists in the construction, combination and arrangement of parts hereinafter 'described and claimed.

In the drawings forming part of this specification,

Figure 1 is a perspective View of the invention.

Fig. 2 is a vertical 2 2 of Fig. 1, and

Fig. 3, is a horizontal sectional view on line 3-3 of Fig. 1,

A designates a rectangular box-like casing or shell formed with a flat top 1, a bottom 2, side walls 3 and 3', and a back 4. B designates a curved deileetor plate secured by means of bolts 4 to the wall 4, and extending laterally between t-he side walls and spaced above and below, a distance from said top and bottom, so as to form a hollow floor and a hollow roof effecting air spaces or chambers C and C', said chambers being symmetrical about a longitudinal vertical plane located central of the casing. The top 5 and bottom 6 of the detlector plate which constitues a lining for the casing, is curved toward the front of the latter in a manner to form an arcuate floor b sectional view on line Specification of Letters Patent.

and ceiling C for the space within the lining which constitutes the combustion chamber. At its front the casing is formed with an upper and lower front wall and 8 respectively, said walls joining with the walls l and 2 respectivelyY and with the horizontal long edges of the lining to corn Jletely inclose the air spaces C and C. he walls 7 and 8 are spaced vertically to form a long main hot air front outlet opening D of uniform height extending across the front of the casing and being located nearer the bottom to the top of the casing. Supported by the walls 3 and 3. soas to extend from one to the other, horizontally ofthe casing at a position midway between the front and rear walls of the latter nearer the ceiling c of the lining than to the lower edge of the wall 7 is the burner E. The burner consists of a horizontally disposed pipe 10 closed at the end supported in the wall 3, and extending through the wall 3', and having at its outer end a suitable gas valve 11 having a ribbed cone end 11', whereby the supply of gas may be cut ofi'.

Adjacently surrounding the pipe 10 and cutting through the wall 3 are a plurality pf perforations 12 which constitute air inets.

Along its upper side the burner pi e 10 is perforated at regular intervals with a row of jet openings 13, over which positioned in direct vertical alinement is a row of vent openings 14, cutting through the lining B, said openings being spaced at longer intervals and cut to larger diameter. Altei-hating individually with the vent openings 14, and arranged in a row directly above the latter are the discharge openings l5, cut through the top plate 1 of the casing. Obviously, the aggregate area of either the vents or the discharge openings amounts to but a fraction of that of the opening D.

A suitable rail 16 Ispaced a distance above the top plate l, serves as a support for large utensils (Fig. 2) and a guard against displacement for the smaller ones.

In use, the larger part of the heated air will be discharged through the main discharge opening D in the usual way, the balance passing through the comparatively small vents 14 into the chamberC,and thence, as indicated by the arrows through the secondary discharge openings 15. By alternating the openings 15 with the vents 14, the air is deflected from a straight course and thereby retarded in its movement, thus assisting in forcing the larger volume of air through the main discharge opening D.

By having the burner jets nearer the perorations in the lining than to the opening D, the entry of the heated air into said per-v foration is facilitated. Y

The hollow fioor of the device serves at once as an insulating medium whereby the air within is protected against cooling prior `to passing through the opening D, and as a protection to the floor of room` against scorchingl j j j Y I claim: t l

In a combined heater and cook stove, the combination, a rectangular 'long casing having flat surroundin outer Walls and a at top and bottom, said top having a row of holes, and the front wall having a long narrow heat discharge opening for dis charging heat into the room, said opening extending to the end walls and being located as a whole, nearer the bottom than the top of said casing, a lining sheet for the casing extending longitudinally of the ca sing to the end wallsthereof, and transversely of thecasing in a curve from the 'upper edge of said opening upwardly to a point adjacent the top,and downward into contacting relation with a vertically point on the rear wall and then adjacent to central i a point longitudinally central of the bottom and terminating at the lower edge of said opening, whereby is formed ank upper and lower air chamber located respectively directly under the top, and immediately above the bottom of the casing, the transverse section of said air chambers being approximately symmetrical about a vertical longitudinal plane central of the casing, whereby the heated air will-be evenly distributed on either side ofsaid planein said "chainbers, a row of perforations in the top of said lining arranged longitudinally central of the casing, and being appreciably smaller than said holes in the top of the casing, a gas burner havingfa rowy ofgas outlets ex: tending longitudinally centrallyl of. the `casing and located nearerfsaid perforation's than to the upper edge. olt said heat discharge opening, so as to Jform an `upper relatively deep area between said burner and said opening, whereby to facilitate the entry of the rising heated air Jfrom said jets throughsaid perforations in the lining and said holes in the top of the casing, and airrinlets in the end Wall of said casing adj acently surrounding said burner, said air inlets being wholly above said heat discharge opening.

In testimony whereof l affix my signature;
