IMPROVEMENT IN COOKING-STOVES.

Specification forming part of Letters Patent No; 86,499, dated February 2, 1869; reissue No` 5,1203, dated December 24, 1872.

To all whom it may concern:

Be it known that I, NATHANIEL A. BOYN- TON, of the city, county, and State of New York, have invented an Improvement in Cooking-Stoves, of which the following is a specication:

Nature ami Objectsoj' the Invention.

The invention relates, irst, to an ash-pit extending under the oven, in combination with a supplemental oven or warming-chamber sep arated from the said ash-pit by a suitable par- Description of the Drawing.

Figure l represents a vertical section of my improved stove in the plane w min Fig. 2.

' Fig. 2 represents a vertical section in the plane y y in Fig. l. Fig. 3 is a view of the exterior of the door E and of the tail-piece. Fig. 4 is an inside view of the door with the tail-piece.

General Description.

This invention relates to cooking-stoves 5 and consists in several features of improvement, as hereinafter described, and as shown4 in the drawing.

The letter A designates the stove, which may be made of any desired proportions or shape, provided the principle of my improved construction and arrangement is adhered to. The top of the stove is provided with boilerholeswhich can be conveniently arranged without crowding, because the exit-due is made to leave the stove at its side instead of at its top. The letter B designates the nre-chamber, whose grate, C, is revolved in the usual manner by a wrench applied to the end of one of its journals. Below the level of the grate C is an opening or poke-hole, D, in the Wall of the iirechamber, the object of which is to allow a poker to be inserted below the grate to clear it of ashes and cinders by that means. The opening D is closed by a balancing-door, E, which is seen in edge view in Fig. 2, and in front view or elevation in Fig. 3, and which is so constructed and arranged as to remain either open or closed by gravity, without requiring any fastening, said door being made with a tail-piece, F, which is received within the stove, where it swings or vibrates up and.

down when the door is opened and closed. The tail-piece F is connected to the door by a horizontal plate, G, which is concave on its under surface, and forms a shoulder that rests on the bottom edge of the opening D, and allows the door to turn ou such edge, the said plate G being made of such length as to tit easily between the sides of the opening, but that part of the door which remains on the outside of the stove is Wider and longer than the opening D, and its edges .consequently overlap the sides and top of the opening, The tail-piece is also made wider than the opening. This greater width of both the door and tail-piece, as compared with the width of the opening D, prevents the door from falling out of its place. In order to remove the door from the stove and put it in place again, it is only necessary to turn it up sidewise, so as to bring one of its edges opposite one of the upper angles of the opening or door-Way, when itcan be easily pushed in or taken out. The door and tail-piece are arranged in diierent planes in such a manner that when the door is closed the center' of gravity of the parts will fall in-4 side of a vertical plane, passing through the line of support of the door, where the hollow or concave shoulder G rests on the bottom edge of the opening or door-way D, thereby keeping the door up close against the stove. When, on the other hand, the dooris opened and turned down to its lowest position, the center of gravity is brought outside of the line of support, and the superior weight of the door keeps it down, the edges of the tailpiece abutting against the inside edges of the door-way D and preventing the door falling away from the stove. Below the grate Gis the ash-pit H, which occupies the whole space between the grate G and the bottom-plate I of the stove. In the ash-pit I place a movable tray 0r ash-pan, J, of sufficient size to receive-the whole contents of the fire-box or chamber B. The tray or ash-pan J is removed and replaced through the door-way K. The oven L is directly behind the fire-chamber,

, upon the front side of said oven.

and is so arranged that its bottom plate is below the level ofthe grate C, whereby some of the heat which radiates from the lire past the bars of the grate is allowed to act directly Below the oven L is a warming-chamber or supplemental oven, M, which occupies the space between the main oven and the bottom of the stove,

and between the ash-pit and the back plate of the stove. The division-plate O, which separates the ash-pit from the chamber or oven M, may be provided with holes N, through which any cool air which gains access to the chamber M will pass out to the re by the natural draft of the stove. The chamber or supplementary oven M is provided with a door on the same side as 4the usual door to the main oven L, and the usual dues pass under the oven L and behind it, and connect withA the exit-pipe on the side of the stove.

It will be observed that by means of my invention I obtain, in addition to the main oven yin which the highest heat for baking is obtained, a warming-chamber or supplementary oven within the walls, of the stove, in which chamber I can place articles that are removed from the main oven and which require'only a moderate degree ofheat to perfect them, while ythe main voven is continued in use for baking with full heat, thus doing away with any necessity for opening the main oven in order to perfect its contents under a less degree of heat. The chamber M can also be used t0 bring articles to a moderate degree of heat, and also to warm the apartment when the door of the chamber is left open.

It will also be observed that, by means of the construction and arrangement here shown, a considerable part of the large amount of heat which is found in the ash-pit is saved or utilized by being communicated to the chamber MA through the divisionplate O. The chamber M can also be used for the ordinary purposes of a hot-closet,.aud it can also be used as a receptacle for coal or other fuel, any

. gases which may be `generated therefrom by the gentle heat being allowed to escape through the holes N into the ash-pit and lire-chamber, where they will be burned. It may also be used for drying kindling or other wood, and otherarticles, and for any 'other purposes to which a hot-closet may be put.

Several advantages result from extending the ash-pit under the oven. Of these I mention three. First, it affords a large roomy ashpit, and permits the use of an extra large ashpan under the grate without boxing out the end of the stove. Second, it affords space for all necessary appliances for providing a free draft through the ash-pit without obstruction from. the accumulation of ashes. Third, a large roomy ash-pit enables the air to be partiall y heated before passing through the burning fuel, producing a more quick and thorough combustion.

I do n ot claim the supplementary hot-air chamber M, as'I am aware that this is not new in itself.

Claims.

The following is claimed as new: 4

1. The extension of the ash-pit under the ovenin combination with th warming-chamber or supplementary oven at the back or side of the ash-pit, separated therefrom by a perforated or other partition, substantially as and for the purpose specified.

2. The perforated division -plate O which separates the ash-pit H from the supplementary oven M, substantially as described.

3. The opening D in the wall of the stove at a point below the level of the grate, substantially as described.

4. The balanced door E, provided with a shoulder, G, which forms ,its point or line of Y support, and a tail-piece, F, which aids in operating the door, substantially as described and shown.
