SPECIFICATION forming part of Letters Patent N o. 534,736, dated February 26, 1895.

Application filed July 25, 1894.

To all whom it may cof/wenn,.-

Beit known that I, JOHN BALLOU, of Somerville, county of Middlesex, and State of Massachusetts, have invented certain new and useful Improvements in Cooking Stoves or Ranges, of which the following is a specifica` tion, reference being made to the accompanying drawings, in which similar letters refer to similar parts, and in which- Figure l shows an isometrical view of a stove or range containing my invention, portions of the stove being broken away to display the invention more clearly as to the interior arrangement. Fig. 2 shows an isometrical View substantially like Fig. l but giving an exclusively exterior view. Fig. 3 is a vertical section of a range on lineX X, Figs. 1 and 2.

This invention relates to cooking stoves or ranges and especially that class known as portable ranges, and the invention consists in the combination and arrangement of dues and dampers in connection with the tire chamber and ash or sifting chamber of a range, and the object of which is to provide means by which communication of the most positively direct character is effected between the fire chamber, or ash or sifting chamber, and, the chimney, for purposes hereinafter set forth more specifically.

A, represents a flue extending horizontally the entire length at the back and at the outside of the range, the top B, of the range forming also the top of the iiue', all of the products of combustion passing directly from the flue A to the chimney.

At the end of the Hue A or that portion adjacent to the fire Vchamber C, an opening D is provided, communicating with the upper part of the fire chamber, and to which opening a damper E is fitted. At the same end of, and from the fine A extending vertically, is a branch flue F communicating with the sifting (or ash) chamber G by means of the opening H, the vertical line F being provided with a damper I. Immediately over the vertical flue F, and in the top of the due A, is provided an aperture J adapted to receive a collar, or smoke pipe to convey the products of combustion to the chimney.

From the foregoing description it will be seen that the flue A-Which as is usually constructed in stoves of this character terminates at or near the center of the back ofthe Stove,- is in this invention extended to the extreme fire chamber end of the stove and communieating with the fire chamber, permits the products of vcombustion to pass to the chimney by the most direct means possible while the vertical ue F communicating with the sifting (or ash) chamber, furnishes similar direct passage from that apartment to the chimney.

The advantage of the form of construction presented in this invention, consists in the fact that by means of this direct passage from the lire chamber to the chimney, a fire may be maintained in the fire' chamber and the products of combustion-naturally taking the most direct or shortest course to the chimney-Will pass through the opening D, thence to the chimney, and thus, a fire of considerable volume may be maintained, and over which a considerable amount of light cooking may be accomplished,-not of course using the ovenwhile the major portion of the stove will be entirely cold, features that are verydesirable and duly appreciated by the housewife during a large portion of the heated term of the summer months. By this direct course to the chimney of the products of combustion, and especially in connection with a smoke pipe fitted to the aperture J or J', not only are the advantages above set forth attained, but by means of this short course to the chimney the draft of the stove is greatly increased and the kindling or starting of the fire facilitated. i

The damper E may be adjusted by means of the handle K, to close the opening D at the will of the operator, following which, the products of combustion will pass around or over the oven, following the course common to this class of stoves that are provided with the usual fines and damper-s. y

The advantages of the vertical flue F, are that by means of the communication with the sifting (or ash) chamber G, when the fire grate is shaken or dumped, the dustarising from the ashes, are by the draft of the IOO chimney drawn through the opening H and up the chimney, thus preventing its escape through the various crevices about the door of the stove, or to be carried up and deposited within the lues surrounding the oven.

The damper I by means of the handle L, may be adjusted to close or open the iiue F as may be desired. The damper I as shown in the drawings is arranged to lie upon the bottom ot' the iiue A, and is drawn in or out in a direction corresponding to the length of the flue A, While the damperE is arranged to swing from a vertical position When closed, to a position approaching the horizontal when open.

The objects of thedampers I and E being simply to permit the apertures H and D respectively to be opened or closed as may be desired, they may either, or both of them be varied in the arrangement or construction Without departing from the spirit of the invention.

A series of apertures J, M, N, one at each end and one in the center at the top of the flue A, to either of which a collar or smoke pipe may be iitted, While corresponding apertures J', M', N', of a similar character and purpose at the back of the iue A admit of the smoke pipe being placed at either end or the center of the stove as may be most convenient, but for the purposes of this invenion the aperture J, or J', is deemed most deH` sirable. f

The drawing Fig. 3 shows the ash chamber O as au apartment distinct from the sifting chamber G. Many ranges have only one apartment here, and for the purposes of this description these may be regarded as one apartment.

I claim- 1. The combination in a range or stove of a horizontal ue adapted to carry off the products of combustion and extending from the fire chamber end ot' the stove and connecting with the fire chamber and provided with a damper, and a branch vertical ilue provided with a damper and connecting With the sifting (or ash) chamber as and for the purposes described.

2. The combination in a stove or range of a horizontal flue extending from the iire chamber end ot' the stove and adapted to carry off the products of combustion and connected with the fire chamber, a branch vertical flue' connecting With the sifting (or ash) chamber, the apertures over or opposite the vertical flue and adapted to receive a collar or smoke pipe, and the dampers E and I( JOHN BALLOU` Witnesses: JOHN DEMAREsT,
