Letters Patent No. 110,305, dated December 20,1870,

IMPROVEMENT IN .COOKING-STOVES.

The Schedule referred to in these Letters Patent and making part of-the same.

We, DAVID STUART and Lnwrs BRIDGE, both of Philadelphia, county of Philadelphia, State of .Pennsylvania, have invented an Improvement in Cooking- St'oves, of which the following is a specification;

Nature and Object of the Intention.

Our invention relates to certain improvements in the cooking-stove for which Letters Patent were granted to our assignees, Stuart, Peterson & 00.,-

Description of the Accompanying Drawing.

Figure 1 is a sectional perspective view of our im proved' cook-stove Figure 2, a plan view Figure 3, a perspective View of part of the rear of the stove; and

Figures 4 and 5, views of detached portions of the stove. 4

General Description.

A is the fire-place of the stove, to which fuel is admitted through the usual opening a, in front, I) being the grate, and

B, the hearth-plate.

D is the large oven;

E, the small oven of the stove; G being a plate sit uated above the fire-place, and providedwith suitable holes for receiving culinary utensils.

The back of the fire-place consists of an inclined plate, (I, the upper portion 01' which is made horizontal, and is so arranged as to be midway, or thereabout, between the plate G and the top of the large oven D, between which oven and the said plate (I is formed a flue, e, passing downward and communicating with the horizontal fiuef, between the bottom of the-oven and bottom plate of the stove.

- At the rear of the oven is a hollow projection, F, formed by the curved plate g and horizontal plate h, which has two openings for receiving culinary utensils.

So far the stove is-similar to that for which the aforesaid Letters Patent were granted to our said which can be fitted aplate, M, fig. 4, having lips, in w, for fitting into slots in a flange, w, on the stove, the plate having at its lower edge a lip, y, fitting into the opening M at the rear of the stove.

\Vhen the plate M is fitted to its place, the rear of the stove is equivalent to that of an ordinary stove but this plate maybe removed and h'ollowprojection, F, fig. 5, which has lips like those of the plate M, may be fitted to the opening M, at the rear of the stove, when the latter will assume the form seen in fig. 1.

This changing of the stove from one having a plain back to one having the projection F may be etfected in the patterns, which, may be so constructed that the back plate will be cast plain 01' with the hollow projection F.

Within this projection is a plate, 1), on which rests a sliding damper, 1 by moving the latter to the position shown in fig. 1, the products of combustion from the flue f may be made to pass outward and return between the plate It and the plate 11, to the rear fluej, between the back plate 6 and the ovens.

On sliding the damper outward, however, the communication between the lower flue f and rear flue j will be direct.

This rear flue'j will communicate directly with the exit-opening F, if the sliding damper t, on the top of the upper oven, be moved inward; but the communication between the rear flue j and exit-opening wui be cut offif the damper be moved outward.

In the fine immediately behind the .firc-place is a damper-,1, which may rest on the top of the lower oven, as shown, or may be turned so that its edge will rest against the lower frontcorner of the oven, as shown by dotted lines, in which case the products of combustion will pass upward through the flue m of the upper oven, and through the fine n to the exit-opening, while, if the damper x be depressed,

part of the products of combustion will pass between the two ovens.

In fact, it will be seen, without further description, that by manipulating the dampers x, t, and y,

the products of combustion may be directed to any part of the stove which circumstances may suggest.

-lo prevent dust and ashes or particles of fuel from passing over the end of the plate d, I secure to the same a serrated guard 16, seen in fig. '1, and should any particlps pass this guard they are prevented from falling into and obstructing the fine 0 by a similar guard, is, secured to the upper front corner of the oven 1).

It will be seen that the guards k and It donot project entirely across the lines, and therefore do not obstruct or interfere-with the passage'of g'ascs through the'flues; that they are so constructed as not to be burnt out or injured by the heated gases, are inexpensive, and can be readily applied.

' Claims.

.1. The plates of the stove, the half-plate, i, and

projection 1 adapted to each other,,as described, so

that the said half-plate and projection may be fitted to the stove, or detached from the same and replaced by a whole plate, as set forth.

2. The guard 70, consisting of projections extending upward from the rear of the plate 11, as described.
