COOKING-RANGE.

SPECIFICATION forming part of Letters Patent No. 645,772, dated March 20, 1900.

Application tiled November 14, 1899. Serial No. 763,930. (No model.)

T0 @ZZ whom t may concern:

Beit known that I, SAMUEL A. WILDE, a citizen of the United States, residing in Taunton, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Cooking-Ranges, of which the following is a specification.

My invention relates to an improved construction of cooking-ranges anda reorganization of the flue system thereof, whereby the oven is uniformly heated on all of its closed sides, with a maximum of oven-space and ample flue-Space for all purposes of a range.

The specilic improvements are fully described below, and pointed out in the claims. They are also illustrated in the drawings forming a part of this specification, in which- Figure lis a horizontal section of the range, taken o`n line X X, Fig. 2. Fig. 2 is a centrai longitudinal vertical section of the range. Fig. 3 is a partial vertical transverse section taken on line y y, Fig. l.

ct is the front wall of the range, to which is hinged a door a', disclosing when open the entire interior of the oven.

d is the rear wall of the range, having secured thereto or integrally formed therewith two vertical iiues B D, separated by a vertical partition C, said lues extending from the top of the range entirely to the floor or bottom plate thereof, where they connect with bottom nues, to be described. They occupy practically the entire width of the oven-space of the range.

l) is the side plate of the range at the right.

e is the side plate at the left, forming the front of the fire-box g, which is lined with nre-brick in the usual manner.

g is the grate. h is the oven, having side walls m n and bottom and top walls o p, respectively.

B and F connects with vertical uptake-flue D. The throat or gap c forms the communication between the two flues through which the draft-current passes around the terminal c of the partition. The vertical i'lues B and D are provided'with dampers B D', which can be swung in the usual manner from 4the open to the closed position, and vice versa, by means of damper-rods q r, projecting to the outside of the range. In the drawings damper B is represented in the horizontal or open position and damper D in the vertical or closed position. These positions are those in which the dampers are set after the lire is well started and when it is designed to heat the oven.

s is the final outlet of the products of combustion, to which the smoke-pipe is attached.

The wall n of the oven is separated from the wall b of the range by but a small interval, leaving an interspace A not in the main path of the products of combustion, but in communication therewith and forming a restricted liuc through which said products can to some extent circulate. lt is much narrower than the iiues proper; but as it extends the entire width and height of the range it has a very considerable aggregate area and circulation enough to keep that side of the oven at the proper temperature, while from its narrowness it takes up but little space and incidentally allows a maximum capacity to the oven. The opposite side m of the oven is kept up to the proper temperature by heat conduction through the fire-brick wall in direct Contact with the burning fuel. It is thus seen that provision is made for heating the oven on five of its six sides, the sixth being closed by the door.

The course of the heating-flame and prod; ucts of combustion is as follows: Passing up` ward from the fire-box, they spread out in a thin sheet over the flue-space at the top of the oven, as indicated by arrows, and pass rearward and diagonally toward the opening B of downtake-tlue B as constrained by the draft,\ damper D being closed,) thence downward behind the oven to the cross-flue E, thence forward through said flue to the throat c', thence around the turn into flue F, asindicated by dotted arrows in Fig. 1, and back to the rear, entering uptake-flue D, passing `upward through said liuc and out at the IOO smoke-pipe. A small portion of the sheet of iiame passing over the top of the oven finds its way downward through the passage A (shown by arrows) and passes thence by degrees into the current running through main flue E, thus giving to space A its function and utility as a restricted or partial flue. To have this function, it is quite important that the thickness of the restricted iiue should be much less than that of the main or free fines; other- Wise it would interfere with the free course of the main portion of the flame and gases through the circuit intended for it by Way of the main lues and impair the action of the draft by causing eddies and short-circuiting.

I claim and desire to secu re by Letters Patentl. In a cooking-range, the combination of the oven, the fire-box adjacent thereto, the sheet-flue extending from the iire-hox over the top of the oven, the vertical downtake and uptake fines side by side at the rear of the range, provided with suitable dampers, the horizontal cross-fines beneath the oven communicating with each other at the front cud and with the respective downtake and uptake lines at the rear ends, and the restricted flue A, at the side of the range opposite the re-boX, in communication With the top sheet-flue and horizontal flue E, but out of the main current, substantially as spccied.

2. In a cooking-range, an oven surrounded by heating means on live sides thereof as follows: a fire-box at one side, a sheet-flue extending over the Whole top, a flue-space at the rear divided by a vertical partition into tWo equal iues, one downtake and one uptake, each provided with a suitable damper, a finespace at the bottom divided by a horizontal partition into two parallel lues communicating with each other at the front, and with the respective downtake and uptake iiues at the rear, and a restricted Hue-space covering the Whole side of the oven opposite the fire-box, in communication with the top sheet-flue and with onebottom flue at the side thereof, substantially as specified.
