SPECIFICATION forming part of Letters Patent No. 444,281, dated January 6, 1891.

Application filed June 3 1 8 90.

To all whom it may concern..-

Be it known that 1, CHARLES F. WALTHEE, a citizen of the United States, residing at Buifalo, in the county of Erie and State of New York, have invented a certain new and useful Improvement in Ranges, of which the following is a specification.

My invention has for its object to improve cooking stoves or ranges; and it consists in IQ the novel arrangement of dampers and defleeting-plates in the draft-flues and in improvements in the construction of the stove or range doors.

Figure 1 is a top view of a sheet-flue double- [5 oven rangehaving my invention applied thereto, the top plate being removed. Fig. 2 is a vertical section onthe line 2 2, Fig. 1. Fig. 3 is a vertical section on the line 3 3, Fig. 1.

While I have illustrated my invention as applied to a double-oven range, I wish to be understood that certain features thereof are equally applicable to stoves and ranges having but a single oven, as will be hereinafter pointed out.

In the drawings, A represents the fire chamber or box,which is situated between the two ovens B B, and is separated from the back flues-by the plate or partition a. From the fire-chamber the products of combustion pass 0 either directly into the smoke-pipe C, or when the direct-draft dampers K K are closed into the top flues D D between the tops of the ovens and the top plate of the stove over the ovens to the downflues E E at the sides of l 3 5 the ovens, thence into the bottom flues F F beneath the ovens, and thence into the back flues G G in rear of the ovens. The arrangement of the fines thus far described is common in What are known as sheet-flue o ranges. The openings g 9 between the bottom and back flues are toward the center of the range-that is, they are at the sides of the ovens opposite the downside flues. This is to insure a circulation beneath the entire 5 oven, and it will be readily seen that if the back flues are unobstructed the products of combustion, taking the shortest course to the smoke-pipe, will follow the course indicated by the dotted arrows in Fig. 2, and that only one side of the rear end of eachoven will be thoroughly heated. To avoid this and cause Serial No. 354,134:- (No model) the entire rear face of the oven to be heated, I interpose in the flues G G the deflectingplates 11 H, which are arranged directly above the openings g g and extend about half-way across the flues, causing the products of combustion to take the courses shown by the f ullline arrows, Fig. 2. To be most effective, these deflecting-plates should be arranged about in the middle vertically of the up or back flues. It will be understood that a deflecting-plate arranged as described is equally effective for the purpose which it serves, whether in a single or double oven range or stove.

In order that the heat may be cut off from one oven and directed entirely around the other, I make use of the dampers I 1, arranged in the fines G G opposite the ends of the deflecting-plates. I Each damper is oper- 7o ated by a slide-rod 2', extending to the front of the range. By closing the damper I and opening the damper I, as shown in Fig. 1, the products of combustion will be caused to circulate around and heat the oven 13, while they will be cutoff from the other oven, which will become cool, and by reversing the position of these dampers the oven B becomes cool and the oven B is heated.

The direct-draft dampers K K are arranged to control the openings from the top flues D D into the top of the back flues G G. These dampers are in the form of plates standing vertically on their edges and hinged each at or near one end at 70 to one end of the plate or partition a, so that when they are swung to uncover the openings into the back flues they stand out over the tops of the oven, as shown in Fig. 1. These dampers are worked by the rods L L, which are pivotally connected with the dampers at Z Z near where they are pivoted, and extend out to the front of the range or other place convenient of manipulation. The reason formaking and arranging these dampers as described is to 5 cause them to act as deflecting-plates when opened or drawn out, so that the heated products of combustion shall be made to take the course indicated by the arrow 1 in Fig. 1, and thus heat the entire top of the stove, Ioo rather than to take the shorter and more direct course indicated by the arrow 2, which would be the case were the damper not to act as a deflecting-plate. This damper and deflecting-plate is applicable to either a single or double oven range.

I am aware that it has been proposed to regulate the direct draft of cooking stoves or ranges by means of dampers set on edge and so arranged that when swung to open the direct draft they occupy a position between the top plates of the stove and of the oven, and that in such stoves it has also been proposed to combine permanently-arranged deflectingplates against which the said dampers would swing, and hence I lay no claim to either of such features broadly; but I believe myself to be the first to have constructed the stove and the direct-draft damper thereof as has been described, whereby there is a free unobstructed flue over the oven, so that when the indirect draft is on the whole stove-top over the oven will be heated, and so, also, when the damper is swung to open the direct draft it projects into such unobstructed top flue and acts as a deflecting-plate to still cause the products of combustion to heat the whole stove-top.

\Vithout limiting myself to the precise arrangementof parts shown and described, what I claim is 1. In a sheet-flue range, a deflecting-plate arranged in the back flue and extending part way across the same and above the opening from the bottom flue, whereby the products of combustion are caused to pursue a tortuous passage through the said flue, anda damper arranged in the rear flue opposite the said deflecting-plate, substantially as set forth.

A stove or range having around an oven the top, the side, the bottom, and the rear flues, the opening from the bottom to the rear fine being at the side opposite the side flue, and there being a deflecting-plate arranged in the rear line over the said opening from the bottom flue about midway vertically of the rear flue, substantially as described.

3. In a double-oven sheet-flue range, the deflecting-plates arranged in the back flues above the openings from the bottom fines, and the dampers arranged in the back flues opposite the ends of the deflecting-plates, substantially as described.

4. In a stove or range, the oven arranged to one side of the fire-box, the partition-plate extending across the rear end of the fire-box and separating it from the back fine, the unobstructed top flue over the oven leading from the fire-box to a line at one side of the oven,'an openingfrom the said top flue to the back flue for the direct draft, and a damper hinged at or near one end to the said partition-plate and arranged to close the said opening or when the direct draft is desired to be swung out into the top flue, and thereby deflect the products of combustion toward the front of the stove and cause them to circulate under the top plate, substantially as set forth.

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