COOKING-STOVE.
The Schedule referred to in these Letters Patent making part of the same.
To all whom it may con'ce-rn- 'Be it known that I, Gnonon li/LEQKERT, of St. Louis, in the county of St. Louis, and State of Missouri, have invented certain new and useful Improvements on Cook-Stoves; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accom pauying drawings, making partof this specification, in which .Figure l is a section, taken vertically and centrally through the improved stove from front to rear.
Figure 2 is a top view of-the fine-passages, situated at the bottom of the stove.
Figure 3 is a perspective view of the bottom flues of the stove.
Similar letters of reference indicate corresponding parts in the several figures. I
The object of this invention is to improve that class of cooking-stoves or ranges which have forward and return fines arranged beneath their ovens, communicating with vertical flues arranged at the backs of the ovens.
In this class of stoves, the fines beneath the ovens have been made of a uniform width and depth throughout, consequently there is an unequal amount of heat distributed to the different ends of the oven, that end of the oven nearest the points where the products first enter the flues being warmest.
To obviate this objection, my invention consists in so constructing the dues beneath the oven, that as the, products gradually part with their heat, they are brought in closer relation to the bottom of the oven, and the heat distributed theretornore uniformly than hitherto, as will be hereinafter explained.
The following description will enable others skilled in the art to understand my invention.
In the accompanying drawings A A represent the top and vertical walls of a cooking-stove.
B is the oven.
0, the fire-chamber, from which latter the products pass over the top plate of the oven to the back fines.
If the central damper, not shown in the drawings, is shut, the products descend through vertically on opposite sides of the central flue a, and enter bottom fines E E, thence pass forward to and through the transverse openings 0 c, into a central flue, D, through which latter the products pass backward to and escape through the central flue a.
At a an opening is made through the front wall of the stove, through which ash-dust and soot can heremoved from the flue D. This opening should be provided with a door. for closing it.
The three longitudinal fines E E and D are formed by two division-plates g g, and inclined bottom plates 71. h.
Th division-plates converge toward the front of the stove and terminate at transverse passages c c, through which the products pass from fines E E into the front end of the central flue D, as indicated by the arrows in figs. 2 and 3.
It will be seen that 'tlie converging plates 9 9 form two laterally diverging side flues E E, and a central diverging flue, D, thus each flue gradually increases in width as it approaches the point where the products leave it.
' The bottom plate h of each flue is inclined, so as 'to give to each flue the greatest vertical depth where it is narrowest, and the inclination of bottom plates h is such, relatively to the obliquity of the division-plates, that each flue is of the same capacity, or contains the same number of square inches at one point that it does at any other point.
Operation.
The highly-heated products are first received beneath the oven B, into the rear ends of the side flues E E, where these flues are narrowest and deepest. The products are thence drawn forward toward the front end of the stove, where the said flues are shallowest and widest, and, in their passage, gradually part with heat and are directed upward by the inclined plates h h, against the bottom of the oven.
The increasedwidth given to the flues E E at their front ends prevents the draught from being obstructed, in consequence of these fines being made of less verticaldepth at said ends than at their rear ends.
The front end of the central flue D is deeper and narrower than it is at its rear end, but this flue, like the side flues E E, is of uniform capacity throughout.
The inclined bottom of this flue D directs the heated currents upwardly against the bottom of the oven, and, like the fines E E, condenses the volume of heated products vertically, while the obliquity of plates E allows the products to expand-laterally.
It will be seen from the above description, that the.
is more uniformly heated, and a large amount of heatis utilized, which, under the old plan of constructing fines, is lost.
The corners of the oven are rounded at p p p, fig. 1, for the purpose of causing the products, in their passage over and behind the oven, to hug its walls closely instead of being directed off, as would be the case if these corners were very acute.
Having described my invention,
, Vhat 1 claim as new, and desire to secure by Letters Patent, is-
The arrangement, beneath the oven of a cook-stove, of longitudinal forward and return fines, which are both vertically and longitudinally tapered, substantially as described.
