IMPROVEMENT IN MAGAZINE COOKING-.STOVES.

Specification formingpart of Letters Patent No. 168,047, dated September 21, 1875 application filed March 4, 1875.

To all whom it may concern:

Be it known that we, JOHN S. PERRY, AN-

DREW DICKEY, and ROBERT Z. LIDDLE, all of Albany, county of Albany and State of New York, have invented certain Improvements in Stoves, of which the following is a specification:

The main object of our invention is to so combine a culinary attachment with an illuniinated heating-stove that the structure of their openings and dampers. Fig. 4, Sheet 2, 4

is a vertical section of the'stove and culinary attachment connected together; Fig. 5, a sectional plan on the line 3 4 Fig. 6, a sectional plan on the line 5 6; and Fig. 7,-a perspective View.

As regards the general conformation of the stove proper, it is similar to the ordinary illuminated heating-stoves now in common use, having an outer casing or shell, A, composed of the followingparts: the cylinder 12, containing the magazine, and resting on the ring of the upper illuminating-section c, which incloses the combustion-chamber the lower mica section d, containing the fire-pot, and'iuclosing, with the base-section e, the ash-chamber and ash-pit; and the hollow base f, which contains the flues, explained hereafter. At the rear of the stove is the hollow projection F, terminating at the top in the exit-pipe a,-

for the escape of the products of combustion.

G is the culinary attachment, constructed for application to the rear of the base-section of the stove, to which it may be secured by such fastenings as will permit its ready disconnection from the same. This attachment has an oven, 9, flues P, Q, andl. between the culinary attachment is connected to the stove that these openings d 0, and f are of any service, as will appear hereafter, the said openings being closed by removable plates 12, when a simple heating'st ove, without the culinary attachment, is required. Although we prefer to so construct the combined heating and cooking stove that the culinary attachment may be readily connected to, and disconnected from, the heating portion, the two may be so constructed as to constitute permanent parts of each other. In the casing L over the top of the oven there are openings 0 for the reception of culinary vessels, which are heated from the same source which heats the oven g. a

H is the fire-pot suspended in the ashchamber within the lower mica section cl, the sides of this fire-pot being vertical, or nearly so, from the upper edge to about the line 00, below which the sides, together with the projections or'fingers h at the base of the firepot, either together or separately, are curved inward and downward. As this feature forms the subject of a separate application for a patent tiled by J. S. Perry, further description of it will be unnecessary.

It will be seen on referring to Fig. 3 that the interior of the projection F at the rear of the stove is separated by a vertical partition, 19, into a descendingflue, 10 and ascending flue 12 Each of these flues communicates with the combustion-chamber through an opening in the wall of the same, and the line 12 also communicates with the exit-opening a but a damper, k, can be so adjusted as to close the communication of this flue p with the exitopeninga, in which case the products of com bustion must pass off directly from the combustion-chamber to the chimney, or it may be so adjusted as to close the opening between the flue p and the combustion-chamber, in

which case the products of combustion must necessarily pass into the descending fiuep which communicates with a horizontal flue, t,

in the hollow basef. The interior of this hollow base is devoted to two fines, t and t, between which is a partition, V, an opening in the latter near the front of the base forming a communication between these fines and the fine 1', communicating with the ascending fine,

the outer casing L intervenes the lower flue .1, the rear fine Q, and upper fine T, and the attachment is so constructed that it shall fit .snngly against the rear of the stove, the upper ifiue T of the oven communicating with the ascending fiue 10 through openings al while the lower flue 1 of the attachment shall communicate through the opening 0 with the baseflue t, and also through the opening f with the descending flue 132, when the adjustment of the damper it permits such communication. .In kindling a fire in the stove with the cull .nary attachment the damper It should, in the first instance, be turned down, so that the products of combustion may pass directly from the combustion-chamber to the exit-pipe, and after the fire has been thoroughly kindled the said damper It should be turned up,

when the products of combustion will pass ,from the combustion-chamber, through the openingp, down the descending fiuep thence .into the fiue t in the hollow base f, then into the fine t, thence through the opening 6' into the lower fine P of the oven, up the rear fine Q of the same, along the upper fine T through .the opening d into the ascending fine p, and

.through the latter to the exit-pipe a. Thus the products of combustion, by the co-operation of the fines of the stove proper \vith those of the oven, impart the desired heat to both .without any additional consumption of fuel,

and produce at the same time a perfect baking-oven, g, and boiling appliances.

, Should it be desirable to heat the oven rapidly by first directing the products of combustion around the same, this can readily be accomplished by closing the damper k in the flue 1), opening the damper 7c in fine 12 when the products of combustion will pass down the latter flue through the openings f at the base of the same into the tine P under the oven, thence upward through the fine Q at the rear of same, and fine T at the top of the .oven, to the opening d in fine 19 through which they escape to the exitv a. It will thus be seen that by this simple arrangement the products of combustion can be thrown first into the hollow base and thence around the oven, or first around the latter, if a more intense heat shall be desired for culinary purposes.

The products of combustion in passing through the fines P, Q, and T, surrounding the oven g, are distributed so as to most effectually heat the surfaces of the latter by the introduction at the desired points of suitable fine-strips, one of which is shown under the oven bottom at 11 in Fig. 5, Sheet 2.

WVhen the culinary attachment is connected to the stove two chambers, 01 (1 are formed by the extension of the walls of the former to the base-section of the latter, and these chambers we utilize by making them the medium to furtherincrease the heat in the oven without additional fuel, and also for ventilating the same. Air is permitted to enter each of these chambers through openings w, and, becoming highly heated by contact with the surfaces of the base-section of the stove and those of the projection F containing the descending and ascending fines, passes through openings w into the front of the ovenand near the top, and escapes from the same through one or more openings, y, at the rear of the oven and near the bottom into the rear flue Q, whence it passes off with the products of combustion to the chimney. The outlet-openings 3 are covered with self-adjustable valves 3 Fig. 7, which open or close according to the degree with which the heated air circulates through the oven, thus regulating the heating and ventilating of the same. The oven 9 is thus supplied with a constant circulation of heated air, which thoroughly ventilates it.

We do not confine the openings w, 'w, and y to the position shown, but reserve the right to so place them as to produce the best prac tical results. The openings w may be made in the walls of the culinary attachment at the point indicated by the dotted line on Figs. l-

and 2, Sheet 1, and the openings w and y may have their positions reversed from near the top to near the bottom of the oven, and from near the bottom to near the top of the oven, or these openings w, w, and 3 may occupy such relative positions in the structure as shall insure their most perfect co-operation to facilitate the heating and ventilating of the oven g. l We do not claim the combined fire-pot and grate shown in the drawing, and briefly a1- luded to in the first part of this specification, inasmuch as a separate application for a patent for this feature was filed by J. S. Perry on the 24th day of June, 1875; but

We claim as our invention- 1. The combination of a culinary attachment, having fines and openings, substantially as described, with a heating-stove, having an ascending and descending flue upon the rear, and openings by which the said flues may be made to co-operate with those of the culinary attachment, all substantially as and for the purposes specified.
