COOKING-STOVE.

SPECIFICATION forming part of Letters Patent No. 673,946, dated May 14, 1901.

Application filed February 17, 1900. Serial No. 5.646. (No model.)

To if/ZZ whom it may concern.-

Be it known that l, EDWARD G. GERMER, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Cooking-Stoves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to cooking-stoves; and it consists in certain improvements in the construction thereof, as will be hereinafter fully described, and pointed out in the claims.

The invention is illustrated in the accompanying drawings as follows:

Figure l shows a section on the lines 1 1 in Figs. 2 and 3. Fig. 2 shows a section on the lines 2 2 in Figs. l and 3. Fig. 3 showsa section on the lines 3 3 in Figs. l and 2. Fig. 4E shows a perspective view of the bracket for supporting the lire-box lining.

A marks the fire-box, B the grate, and C the oven. These are arranged in the usual relation-that is, the grate is immediately below the lire-box and the oven is arranged immediately adjacent the fire-box.

In the combustion of fuel placed in the .fireboX there is atendencyfor the partly-burned fuel in the lower parts of the box to so act upon the fuel near the top as to expel the gases therefrom, and in fire-boxes of the ordinary con struction the oxygen,which passes through the grate, is largely taken up in the combustion of fuel in the lower part of the fire. Where this occurs, the gases expelled from fuel in the upper part of the box are of course unconsu med and are carried oi`1c with the other products of combustion. This not only eects the loss of the heat-producing quality of these gases themselves, but these gases are also liable to escape from the stove and are disagreeable and of course injurious. To obviate this, I have provided a lining for the lire-box with ducts or fines which open to the space below the grate and extend upwardly in the lining to nearly the top of the fire-box and are in communication with the fire -boX through slits, which preferably extend throughout the entire length of the iiue.

It is desirable to insulate the oven from the intense heat of the fire-box, and to this end these flues form air-spaces between the firebox and the oven, which tend to accomplish this purpose. It will be noted, therefore, that in a cooking-stove, where the oven is adjacent to and at the side of the fire-box, the flues have a double functionthat is, they carry air to the upper parts of the fire, so that the gases expelled by the heat in the lower part of the fire may be consumed, and they form air-spaces, which insulates the fire-box from the oven.

Where a dumping-grate is used, it is desirable to keep the ashes, duc., from the firebox from falling on the gears which control the movement of the parts of the grate. For this purpose I have made the fire-linings at the ends solid and placed them inside of the gears.

I have shown in the drawings a preferable Way of carrying out my invention. In this the front lining` e is made in one piece and is supported at the ends, and the end linings ct are placed in position and joined at the corners with the front lining, so that they hold the front lining in place, and, on the other hand, the front lining holds these end linings in place. This is the usual manner of putting these linings together. The rear lining is formed of three sections a2. The end sections engage the end linings and hold the rear side of the end linings in place, and, on the other hand, they are locked 4in position by the end linings. The central section overlaps the end section and it is secured in place by the lip d3. In this manner all parts of the lining are made secure. The front and end linings being made in one piece can be supported at their ends, but the rear linings being in sections are preferably supported by a bracket as, and this bracket is provided with a rib a9, which prevents the linings from moving forward at the bottom. The rear lining is provided with the iues a4, from which the slits 0.5 extend into the fire-box. The bracket d8 has the openings d10, which register with the openings d4, and the slits d register with the slits e5. This permits a free movement of air from below the grate-space into the iiues and a free exit for any ash that may get into the lues. The flues a4 in themselves form air-spaces,which insulates the oven from the ireboX. I prefer, however, in addition IOO to this to form Vthe depressions C012 between the fines, so that there will be an Yair-space between the fireback and the oven-plate formed by said depressions, thus increasing the insulation effected by the iiues. The exitpassage of the ire-box extends from the side laterally over the oven, as in the usual construction. The front lining is provided with the fiues a6 and slits a7, which operate in the manner heretofore described. The front lining being supported at its ends is of course immediately in communication with the space below the grate.

The grates are preferably of the ordinary dumping form, having the two parts b b, supported bythe rod b b. The gears b2 b2 control the movement of the parts, as is usual With this construction of grate. I prefer to make the end linings solid, soas to prevent the falling of ash on these gears.

l. In a cooking-stove, the combination with the fire-box and the oven, arranged side by side, with a lateral exit-passage extending from the side 0f the fire-box over the oven, of a lining next to the oven-plate and below said passage, having flues arranged within the body thereof and communicating with the outer air, said lining having openings between the ues and that part-of the fire-box designed to hold the fuel, whereby columns of air, forinsulating purposes7 are maintained in the ues 0f the lining, and are introduced into the fuel part of the combustion-chamber in sufficient volu me to maintain the air in the fines at a temperature eifecting an insulation between the fire-pot and the oven, and at a point to facilitate combustion.

2. In a cooking-stove, the combination with the nre-box and oven, of a lining for the lirepot having vertical lues opening at theirlower ends into the ash pit, provided with slits throughout their lengths, opening into the fuel-space of the fire-pot; the lining next to the oven being in sections and having depressions between the iues forming air-spaces to protect the oven-plate, and a bracket supporting the rear lining-sections and having openings and slits corresponding` to the flues and slits in the lining; substantially as described.

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