Specification of Letters Patent.

' Patented Apr. 3, 1917.

Application filed September 18, 1914. Serial No. 862,368.

To all whom it may concern:

Be it known that I, CLAUDE R. JOHNSON, a citizen of the United States, residing at N eodesha, in the county of Wilson and State of Kansas, have invented certain new and useful Improvements in Gas-Stoves, of which i the following is a specification.

My invention relates to stoves and has particular reference to a gas stove for heating purposes, the primary object, of which is to provide a gas stove and means mounted therein for regulating the intensity of the heat. 7

As a principal object, this invention contemplates the provision of a heating stove whereby all of the heat produced by the combustion of illuminating gas will be utilized in the customary radiation in warming a room.

An object of equal importance is to provide in a gas stove a series of battle plates to retard the upward flow of the heated gases produced by the combustion of illuminating gas and which uninterrupted flow has heretofore resulted in a loss of a larger percentage of heat in the burners most commonly used at present but which is so checked by the mentioned bafiie plates that the larger proportion of the heat may be utilized before the heated gases are lost.

A further object is to provide means rendering baffle plates furnished with a heating burner adjustable so that the amount of retardation offered by them to the upward flow of heated gases may be regulated at the will of the user thus affording an easy means of controlling the heat given out into a room by any burner consuming a given quantity of gas.

A still further object is to furnisha heating stove for illuminating gas which while possessed of the advantages set forth in the preceding objects may be simply constructed with such regard to proportion, number and arrangement of parts as to be capable'of be ing cheaply manufactured, while at the same time durable and efiicient in operation.

The above and additional objects which will become apparent as this explanatory description proceeds, are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out in the claim which is appended hereto and forms a part of this application.

With reference to the drawings, wherein there is illustrated the preferred embodiment of this invention as it is reduced to practice and throughout the several views of which like characters of reference designate similar parts:

Figure l is a side elevation of a stove furnished with the gas hended by this invention, parts being broken away and in section to more clearly disclose the interior construction which is vertically sectioned, in

Fig. 2 is a plan view of one of the baffle plates,

Fig. 3 is a similar view of the baffle plate containing the burner,

Fig. 1 is a vertical section taken through the adjustable supports for the baffle plates which latter are shown fragmentarily, and

Fig. 5 is an elevational view of a part of the support shown in Fig. 1, while Fig. 6 is a sectional detail of the burner itself.

Upon reference to the drawings there will be seen a stove 10 of any customary exterior construction presenting the usual appearance of such articles and being provided with radiating apertures 11 in the upper portion thereof while being supported on legs 12 spaced to permit of the admission of air to the interior combustion.

As a means for supporting the burner and baffle plates as novelly provided by this invention, an annular angular flange 13 is secured at a suitable distance from the bottom to the inner sides of thestove 10, upon which flange are adjustably supported baflie plates 14-, 15 and 16 comprising one form which this invention may take. Adjustably supporting these battle plates in spaced relation to each other and to the flange 13 there is provided a means more fully shown in Fig. 1, including a shank portion 17 transversely corrugated as at 18 and formed upon one extremity with a supporting flange 19 whereby the whole support may be secured to one of the plates to be supported. A pair of oppositely disposed shank portions comprise one support, each being slotted as indicated at 20 for the slidable reception of an adjusting bolt 21 passing through each shank and being capable of being tightened thereon in order to maintain the corrugations of one shank firmly seated in the corrugations of the other as will be obvious ""upon the perusal of this figure. Inconnection burner compreof the stove, as an aid to with the support of the baflie 14 it may be noted that the upper mating corrugated section may be mounted directly on the downwardly bent perimeter of that baflie with out the interpositionof the adjusting shank,

if so desired.

. Suitable pipe connections 26 of an approved style may be utilized as a'means for conveying the combustible gas to the burner 22.

The second baffle 15 is immediately superimposed over the lowermost baflie and is formed more nearly semi-spherical in order to project beyond the abrupt edges of the lowermost baflle plate and to catch the heated gases as they issue from the latter on their upward way. This second baifle is provided with a central aperture 15 and emits the gases directly against the third baffle plate 16 which is similar in shape but formed with no central aperture so that the course of the rising gases corresponds more nearly with those leaving the lowermost baffle.

From the foregoing, it should be seen that a construction of a gas stove has been provided which as described is capable of retarding the usually rapid passage of a heated gas created by the immediate previous combustion of a combustible gas so that the slower upward movement will permit of a larger portion of the heat to be utilized before it is permitted to escape. The bafiie plates may be formed from sheet iron, light steel or any other metal which should be quickly brought to a glowing heat by being interposed in a direct path of the heated gases so that by radiation of the baffle plates as well as of the increased radiation of the gas itself a larger amount of heat may be distributed than formerly on a given quantity of gas. It will be obvious that this invention need not necessarily be limited to portable heating stoves such as shown in the drawings but may be applied with equal efiiciency to smelting furnaces, locomotive and marine boilers, power plants, cook ovens or any heating system in which it has been heretofore impractical to use gas as a heat generating fuel on account of the cost.

While in the foregoing however, there has thus been illustrated in the drawings and described in the specification such combination and arrangement of elements as constitute the preferred embodiment of this invention, it is desired to emphasize the fact that such minor changes in the matters of proportion and degree may be made in later adaptations of this device as shall not alter the spirit of the invention as defined in the appended claim.

What is claimed is The combination with a casing and a burner mounted therein, of a baffle plate engaging the burner above the burner openings, an annular rim mounted in the easmg, supporting members detachably engaged in the bafiie plate and supported on the rim, the baflie plate being vertically adjustable on the supporting members, additional bafile plates arranged in the casing one above the other, supporting members mounted on the baffle plates, and supporting members depending downwardly from the last mentioned bafile plates and adjustably engaged with the first named supporting members whereby the distance between any two of the bafile plates may be varied.

In testimony whereof I aifix my signature in presence of two witnesses.

CLAUDE R. JOHNSON.
