ATENT RANG E'. OR STOVE.

SPECIFICATION forming part of Letters Patent No. 594,974, dated December 7, 1897.

Application filed April 2 6 1 8 9 '7.

To @ZZ whom it may concern:

Beit known that I, LAWSON TAIT, Fellow of the Royal College of Surgeons, a subject of the Queen of Great Britain, residing at 195 Newhall Street, Birmingham, in the county of Warwick, England, have invented certain new and useful Improvements in or Relating to Ranges or Stoves for Cooking, of which the following is a specification.

These improvements are directed toward the greater economy of fuel, the reduction of town smoke from domestic fires by the more complete combustion of the fuel, the reduction of heat in kitchens in Ythe process of cooking, the simplification of cooking-ranges in the reduction of parts which maybe broken or lost, the better regulation of the continuity of heat in the process of cooking, and the diminution of labor in the process of stoking and cleansing of range; also, the better and more economical use of the refuse of combustion and the better supply of hot water for domestic purposes.

- Figure l of the annexed drawings is a front elevation of a double or two oven range constructed in accordance with my invention. Fig. 2 is a sectional elevation. Fig. 8 is a plan. Fig. it is a sectional plan. Figs. 5 and 6 are transverse sections. Fig. 7 is a back view in section, the section being taken close to the back plate of the stove.

Referring to Figs. l to 6, the range here shown consists of an oblong case of metal of a size to suit the requirements and divided, as usual, into various compartments with oven and boiler spaces, flues, and ash and cinder pan.` The fire-box A is placed centrally, and the range has an oven on each side of the fire-box, (marked B and L.) A tubular-coil boiler C is placed at the back of the oven B, with draw-off pipe D and tap E going to the front of the range. The boiler is also connected with a circulating tank or cylinder and Water-supply. The fire-box is a columnar spa-ce extending in a sloping direction from before backward and downward at an angle of about thirty degrees, closed in front by an accurately-fitting lid F and open at the far or lower end with a set of removable fire-bars G. On the lower surface of the fire-bars a sliding dampenplate H is fixed. It is carried Serial No. 634,031. (No model.)

by grooves and is worked by a handle at the front of the range with toothed stem J, so that the access of air can be completely shut oif from the fire or regulated as circumstances may require, the heat of the whole range being governed by the air-supply being admitted or shut off by this damper.

Vhen the fire is lighted on the hre-bars G and well established, the lire-box A is filled with small coal, coke, or other fuel, and it is fed from the upper end as may be required. The column of fuel burns at its lower or farther end. Thus the reserve fuel is not baked andthe valuable gases are not given off as deleterious smoke before being utilized. Even such gas as may so be driven off is niet as it issues from the fire-box by a hot-air blast, which is drawn through a pipe K, passing through the hot oven, or the hot-air pipe may be led through the fire-box or flue, as shown at V. In this way the gas is effectually and economically consu med. After the range has been effectually started if intelligently used it may be indefinitely continued in use without the production of more smoke than is just visible at the outlet of the chimney. It is impossible for any one to produce the volume of smoke emitted by ordinary ranges when the fire is, as the term goes, made up. A very great economy of coal by this means is effected and the reduction of smoke is most remarkable. f

From the iire-box A, near its lower end, the

h'ot gases pass through the lateral opening a the oven B, past the outlet ofthe hot-air pipe 4 and chimney. The course of the hot gases.

as thus traced is also indicated by the arrows numbered, successively, l to 10.

The top of the range consists of a hot plate O P, of large size and uninterrupted surface,

with temperature at different parts varying for all the requirements of cooking from rapid boiling, at O, to that of merely keeping a pot warm, at P. Holes may be cut at R R for the insertion of sauce or other pans, but the range will work better if such holes are not made. In the upright diaphragm at X on the top ot the hot oven apertures may be cut under the holes R R to increase the effectiveness of this part of the hot plate.

The top plate is removable for purposes of cleaning by screws at the corners or there may be studs conveniently placed on the castings. The lid F of the fire-box is hinged so that it cannot be removed or broken without unreasonable violence.

The ovens are of ordinary or convenient size. One is hot, or for rapid cooking, the other is cool, for slower cooking or for keeping things hot.

From the method of combustion of the fuel adopted in this range the production of soot is much diminished. The fines, however, are so arranged that when the top of the range is removed all deposit of soot or dust on the outside of the oven-walls and on boilertubes can be easily brushed off, and it falls into the soot-hole in the pediment of the range. These soot-holes Y Y are closed by the ash-pan S T. Vhen the ash-pan is removed, large holes Z Z, right and left, are eX- posed, and through these the soot can be brushed out.

The ash-pan S T is an oblong box without cover divided into two compartments by a transverse division. The compartment S immediately under the fire-box is for the dust. The front one T is for the cinders. The dust is separated from the cinders by a grid U, which runs slantingly downward and forward from the far end of the bars of the rebox to the division of the ash-pan.

The cinders may be used over again with advantage, mixed with the coal or other fuel. The fire-ashes will be found to be valuable garden manure or the very best material to use for an earth-closet.

The single range is substantially as the double range, omitting the cool oven and the parts immediately connected therewith.

In the case of the single range the products of combustion pass from the top of the oven B through an aperture leading out of the passage M straight into the flue N.

The employment of a tubular boiler C to these kitchen-ranges effects further improvements, giving a good hot-water supply and removing the diiiiculty encountered in getting servants to clean out the arches of the boilers ordinarily employed.

There is further the advantage that in these ranges the boiler can be removed and re placed without disturbance of the other parts of the range in the event of accident to the boiler or its being worn out.

There are also further advantages in that by filling the fire-box, closing its lid, and closing the damper the lire may be made to burn at a slow rate for about twelve to fteen hours without further attention, thus securing a perpetual hot-water supply and a iire which will be in active combustion afterhavin g been closed all night.

l. The combination of the outer casing with removable top, the two ovens within the casing, the fire-box between the ovens and eX- tending from front to back of the casing, the side walls of the fire-box continued to the top and bottom of the casing, the space below the fire-box forming the ash-pit, the line-spaces at the back and on the outer sides and above and below the ovens and above the tire-box, the opening from the lower part of the iirebox into the space at the back of the oven and the openings from the spaces at the back of and below the ovens into the lower part of the ash-pit, and means for normally covering or closing these openings, so that by removing the top of the casing and uncovering said openings into the ash-pit the whole interior of the range can be cleaned with facility.

2. The combination of the outer casing with removable top, the tire-box inclining downward and extending from front to rear of the casing, the side walls ot' the iire-box continued to top and bottom of the casing, the space below the fire-box forming the ash-pit, the oven at one side of the fire-box, the flue-space at the back of the oven, the exit for the products of combustion from the fire-box to pass into this space, the spaces at the outer side of and above and below the oven and above the inclined fire-box opening one into another in such way that the products of combustion from the fire pass first to the back of the oven then up its outer side and over its top and afterward over the top of the inclined fire-box.

3. The combination of the outer casing, having a removable top, the centrally-located firebox closed at the top and inclined from the front downwardly, the ovens, one 0n each side of the fire-box and having spaces around them for the circulation ot' the products of combustion, a passage connecting one end of the circulating-space that is around one oven with the tire-box, a passage across the closed top of the lire-box connecting the other end with one end of the circulating-space around the second oven and a passage connecting the other end of said last-named circulating-space with the outlet or chimney.
