H. H. STIMPSON, OF BOSTON, MASSACHUSETTS. IMPROVEMENT IN COOKING-RANGES.

Specification forming part of Letters Patent No. 3,587,

August 8, 1846;

.To all whom it may concern:

Beit known that I, HERBERT H. STIMPSON, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in the Cooking-Range; and I do hereby declare that the following is a full, clear, and exact description of the principle or character which distinguishes my inand of the manner of making, constructing, and using the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure 1 is an elevation of the front of the range; Fig. 2, a transverse central and verwhile they pass around the oven, and only uniting in the chimney after acting on the oven, whereby the heat can be re ulated on any part of the oven, the temperature of one part increased or decreased at pleasure by means of the dampers without producing a corresponding change in the other parts.

In the ranges made prior the oven is heated which circulates around it in various directions,

.on each communicates being observed at each end of the oven.

dated May 17, 1844,- Reissue No. 84, dated be greatly varied without changing the principle of my invention, which, as stated above, consists in heating the oven by means of the three independent fines. .The modein which I have applied this principle is fully represented in the accompanying drawings, in

A is the fire-grate, and B the boiling-chambers, of the usual construction, the top plates of the boiling-chambers being provided with boiler-holes. The grate or fire chamber communicates directly with the boiling-chambers side, and from each of these chambers there is a horizontal a damper, e, (in the usual manner,) which with a vertical flue,'C', end h of the oven E, which is placed back of the fire-grate, so that the heated air and products of combustion pass up this flue and in contact with a portion of the end plate of the oven, and thence over the forward portion of the top to the vertical partition F, and out through a hole, G, in a vertical partition, G, above the oven, to the chimney-flue H, the partition G being a continuation of the vertical partitions (Z d, the same arrangement main flue K passes directly from the back of the fire-grate, under the oven, intoa vertical flue, c, at the back of the oven, and which extends around the ends thereof, as at L, to the vertical partitions d d, that separate this from the lateral flues C 'G. This main flue leads into the flue-space I over the back part of the chimney H through an aperture in a horizontal plate, which the draft by a valve, 1),, by can be regulated in the main flue; but it will be obvious that the valves for regulating the draft in the three flues may be placed differently, as this arrangement is merely pointed out as that mode of applying the principle of my invention which I have adopted and deem the best.

I do not claim as my invention heating the oven of a cooking-range by means of the main flue separately, or by means of the two lateral flues after passing through the boiling-chambers; but

What I do claim as my invention, and de sire to secure by Letters Patent, is

Heating portions of the oven of a cookingflue, O, governed by range by means of the two lateral fines, substantially as herein described, in combination with the main or direct flue, by which-the other portions of the oven are heated, the three fines being separate while acting on the oven, substantially as described, whereby the heating of the several parts of the oven can be regulated by each flue acting independently of the others, as herein-described.
