STOVE OR RANGE.

SPECIFICATION forming part of Letters Patent No. 568,769, dated October 6, 1896. Application filed April 2'7, 1896. Serial No. 589,278. (No model.)

To all whom it may concern:

Be it known that we, MAX M. KOCH'and JOHN ERBEN, citizens of the United States, residing at Cleveland, in, the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Stoves or Ranges; and we do 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.

Our invention relates to cooking stoves and ranges, and it has for its general object to provide a cooking stove or range embodying an adjustable draft-regulator, which is so constructed andarranged in the stove or range that when in one position it adapts the stove or range for burning bituminous or soft coal and when in another position adapts the stove or range for burning with equal efficiency anthracite or hard coal, the said draft-regulator being also designed to retain the heat beneath the oven of the stove, so as to economize fuel,or to permit a free passage of the heat from be neath the oven, according to the character of baking that it is desired to do,

The invention also contemplates providing the draftregulator with indicating means whereby the cook or attendant may readily ascertain whether the said regulator is in a position to adapt the stove for burning hard coal or in a position to adapt it for burning soft coal.

The invention still further contemplates embodying the draft-regulator in a stove or range equipped with a removable smoke-box and arranging it in such a position with respect to said smoke-box that when said smokeboX is removed ready access may be had to the draftregulator for the purposes of repair or replacement.

Other objects and advantages of the invention will be fully understood from the following description and claims, when taken. in conjunction with the annexed drawings, in which Figure 1 is a vertical longitudinal section of a stove or range embodying our invention. Fig. 2 is a transverse section taken in the plane indicated by the line 00 :0 of Fig. 1. Fig. 3 is an enlarged detail section taken. in the that is to say, may have a fire-box 2, an ashpit 3 beneath the same, an oven 4, an upper flue 5 and end line 6, and a lower or bottom flue 7.

8 indicates a smoke-box of suitable c011- struction, which is so connected with the side wall 9 of the body 1 in any suitable manner that it may be readily disconnected therefrom and removed when desirable or necessary.

10 indicates an opening which is formed in the wall 0 of the body and effects communication between the bottom flue 7 and the interior of the smoke-box.

11 indicates a stationary partition-wall which extends transversely about half-way across the bottom flue 7 at a point between the end flue U and the opening 10, as better shown in Figs. 2 and 3, and is designed and adapted to prevent a direct passage of the heat and particles of combustion from the end flue 6 to the opening 10, and thereby retain the heat and particles of combustion and cause them to traverse the entire area of the oven-bottom, and 12 indicates the frame of our improved draft-regulator. This frame 12 is of a general rectangular form and is arranged and suitably secured in the flue 7 and against the wall 9 of the stove-body, and it is provided with the opening 13, which preferably corresponds in size and communicates with the opening 10, and is also provided with the slot 14: for a purpose presently described.

The frame 12 is further provided with the lateral flange 15, and within this flange is ar ranged the slidable draft-regulator 16, which is connected with the frame 12 by the bolt 17, extending through slot 14, and has a plurality of apertures 18, preferably of vertical elongated form, as shown.

IOO

The draft-regulator 16 is moved to and fro through the medium of the shaft 19, which is journaled in suitable bearings 20 and in one side wall of the body 1, as shown. This shaft 19 is provided at its inner end with an arm 21, having a branch 92, which is arranged and adapted to move in one of the openings 18 of the regulator 16, or in an additional opening (not illustrated) formed to receive it, so as to transmit movement to the said regulator. At its outer end, which extends outside the stovebody, the shaft 19 is provided with a crank 23, whereby it may be readily turned to move the regulator 16 in the desired position.

In order to enable the cook or attendant to readily ascertain the position of the regulator 10 before and after adjustmentthereof, we provide the cover-plate 21, which is attached to the outside of the stove-body by screws 25 or other suitable means and is arranged immediately below the shaft 19, and the indicator-disk 26, which is fixed on the shaft by a set-screw 27 or other suitable means and is disposed between the plate 25L and the stovebody, as better illustrated in Fig. 4. The said disk 26 is provided adjacent to its upper and lower edges with the words Open and Closed, and it is so arranged on the shaft 19 with respect to the position of the draft regulator that when said regulator is in its open position the position of the disk bearing the word Closed willoccupy a position behind the cover-plate it, while when the draftregulator is closed the portion of the disk bearing the word Open will be caused to assume a position behind the cover-plate 2-1:, and the portion bearing the word Closed will be raised above the cover-plate so as to display the said word. From this it will be seen that the cook may ascertain at a glance the position of the draft-regulator, which is an important advantage. It will also be seen that by glancing at the position of the disk 26 with respect to the cover-plate 24 the cook may accurately judge the position of the regulator when the same is not emirely opened or closed, as is sometimes desirable. \Vhen desirable. the word Hard may be used on the disk 26 in lieu of the word Open and the word Soft in lieu of the word Closed, in order to indicate that the draftregulator is in a position to adapt the stove for burning hard coal or in a position to adapt it for burning soft coal.

When it is desired to burn bituminous or soft coal in the stove or range, the draft-regulator 16 is opened, as shown in Fig. 3, so as to afford a sufficient draft, and when the fire is well started the regulator is closed to a greater or less extent, as desirable. \Vhen so closed, the regulator, by reason of its arran gementin the lower flue 7, will serve to retain the heat beneath the oven, where it will be most efficient in baking, and will also serve to materially economize fuel.

\Vhen it is desired to burn anthracite or hard coal or other free-burningfuel in the stove or range, the draft-regulator is closed, and when so closed a sufficient draft will be afforded through the openings 18 of the regulator to support the combustion, and yet the heat and particles of combustion will be retained beneath the oven 4 for the purpose before described. From thisit will be seen that the location of the draft-regulator in the stove or range as described forms animportant part of our invention. It will also be seen that where there is a very strong or extraordinary draft the perforated draft-regulator 16 will check the draft, so as to retain the heat beneath the oven, which is not true of pipedampers.

None of the parts of our improved regulator are liable to get out of order after short use; but if they do it will be Seen that the arrangement of the regulator with respect to the removable smoke-box permits of ready access being had to the regulator when the smoke-box is removed for the purpose of repair or removal or replacement.

Experience has taught us that the manner of operating the draft-regulator, as above described, must be varied to suit the kind and condition of the hard and soft coal, that is to say, hard coal from some mines have more characteristics of cookingstove coal than hard coal from other mines, and the soft coals also differ, some being softer and more likely to burn freely than others. \Vith our improved regulator the draft may, however, be so regulated as to best promote the combustion of hard and soft coal of different kinds, the regulator being closed to a greater orless extent to suit the kind and condition of hard coal and opened to a greater orless extent to suit the kind and condition of soft coal employed, and get the best 'results. \Vith a little experience a cook can, through the medium of the regulator arranged as described, control the draft and promote the combustion of all kinds of coals and get the best results therefrom, and the said regulator also enables her to retain the heat where it is of the most benefit, to wit, beneath the oven, and not in the smoke-box or in the pipe leading to the chimney.

Having described our invention, what we claim is 1. A stove or range comprising a fire-box,

an oven, a fine above the oven communicating with the fire-box, a fine below the oven, an end flue connecting the upper and lower fines, an uptake communicating with the flue below the oven, a frame arranged in the fine below the oven and against the wall with which the uptake is connected, at slidable and apertured draft-regulator arranged in said frame, a rock-shaft for moving said draftregulator, extending outside the stove, a cover-plate connected to the outer side of the stove immediately below the rock-shaft, and the indicator-disk fixed on the said shaft and arranged in a plane between the cover-plate and the outer side of the stove, substantially as specified.

2. The stove or range described comprising a fire-box, an oven, a flue above the oven oommunicatin g with the fire-box, a flue below the oven, an end flue connecting the upper and lower flues, an uptake communicating with the flue below the oven through an opening in the wall of said flue, a frame arranged in the flue below the oven and against the in side of the wall with which the uptake is connected and a slidable and apertured draftregulator arranged in said frame, and adapted to control communication between the flue below the oven and the uptake, substantially as specified.

3. The combination of a stove or range, a slidable draft-regulator arranged within the stove or range, a rock-shaft for moving said draft-regulator extending outside the stove,
