OVEN- FOR STOVES OR RANGES.
SPECIFICATION forming part of Letters Patent No. 354,748, dated December 21, 1886.
Application filed May 11, 1886. Serial No. 201,812. No modem air in the ovens of cooking-stoves or ranges during the process of baking, roasting, &c.
In the accompanying drawings, Figure 1 is a transverse sectional view of a stove provided the air on its way to the oven.
with my improvements on line 3 4, Fig. 2. Fig. 2 is a longitudinal sectional-view on the line 1 2, Fig. 1. Fig. 3 is a rear view of the door of the stove, partly in section. Fig. 4. is a perspective view of a part of the stove.- Fig. 5 is a sectional view of a modification. Fig. 6 is aview of a damper; and Fig. 7 is a detached sectional View showing the check-valve closed.
A is the outer casing or frame of the stove; B, the inner or oven casing; b, the surrounding flues, and D the oven-door. To the inner side of the door D is attached a lining-plate, E, of sheet-tin or other thin metal, having a series of openings, e, near the bottom, and a series of openings, 6, near the top. A cireu-- lating-chamber, M, is thus formed between the door and lining. The door D has a series of holes, d, preferably at the bottom, for the admission of freshair. In this air chamber or passage M, I place a filtering-diaphragm, consisting of a wire casing, G, which is held in place by a bolt, f, securing the lining E and an ornamental outer plate, F, on the door. The casing G is filled'with a filtering material, (preferably asbestus,) which filters and purifies In some constructions of stoves and ranges this circulating-chamber may be at the back of the oven instead of on the door, as indicated by dotted lines in Fig. 1.
From the top of the oven on the side near the fire-place leads an air-flue, H, opening into the'smoke-flue over the oven, and provided with a check-valve, J. I prefer to construct this flue H with a widened branch, h, Fig. 4, extending slightly over the edge of the firepot of the stove, and thus allowing a small proportion of the overheated air to pass to the fire to assist the combustion, Fig. 2.
The construction of the check-valve in the communication between the oven and the smoke-flue may be varied, and I have shown two constructions in Figs. 2 and 5. In Fig. 2 the check-valve is arrangedat the end of the flue H, where it opens into the smoke-flue. It
consists of a cap, j, perforated at the sides and end, and having within it a loose valve or diaphragm, preferably of mica, which, when there is a pressure of air from the oven, will be at the outer end of the cap, to leave the communication open; but when there is any backdraft in the smoke-fines, the valve or diaphragm j will close to its seat against the end of the flue H and close the communication, as shown in Fig. Z. For some purposes, however,-I prefer to arrange the check-valve at the point where the flue H opens from the'interior of the oven, as shown in Fig. 5. In this construction the valve is shown as normally kept raised against the downwardly-projecting fingers i to keep the passage open, while backdrafts in,the smoke-fines will cause the valve to drop back to its seat in the openended cap j and close the passage. The passage between the oven and smoke-flue is preftop of the oven the overheated air is drawn off into and through the smoke-fines, while the restcontinues its circulation, and fresh air is drawn in through the openings d in proportion as hot air is drawn off into the smokeflues and fire.
I prefer to form the openings e e in the lining E by cutting U-shaped slits in the sheet metal and bending back the tongues thus formed, as shown in Figs. 1 and 3. By bending these tongues to different angles the size of the openings can be varied, and consequently the circulation of air regulated.
I prefer to make use of the standard or support for the top of the cook-stove for the airflue H, as shown in the drawings, and to make use of the portion h to clamp the fire-back in position.
I am aware that ovens have been made with air-heating chambers through which the air shall pass into the oven.
I am also aware that it has been proposed to provide oven-doors with wire-gauze; but such wire-gauze could not act as a filtering medium for the air in the sense in which the filtering-diaphragm in my oven acts.
. I claim as my invention 1'. The combination of a cook-stove or range having an adjacent air-circulating chamber, M, provided with openings 6 from the bottom of the oven into the chamber, and with openings e from the top of the chamber into the oven, and with fresh-air inlets d at the bottom of the said chamber, substantially as specified.
2. The combination of the oven ot' a cookstove or range with an aircirculating chamberhaving a filteringdiaphragm, substanfor the purpose described.
4. The combination of the oven of a. cookstove or range and the top plate with a standard containing a flue forming a communication 0 between the oven and top smoke-flue, as set forth. I
5. The combination of the oven of a cookstove or range, the top plate, and fire-back with a standard supporting the top plate and 3 5 clamping the fire-back, and having fines forming communication between the oven and firepot and the smoke-fines, all substantially as specified.
6. The combination of an oven for cooking- 0 stoves, &c., with a door, D, and lining'plateE therefor, having openings e and e, and easing G, containing a filtering compound, substantially as set forth.
In testimony whereof I have signed my name 45 to this specification in the presence of two subscribing witnesses.
ALEXANDER SLOAN.
