To all whom it may concern..-

Be it known that I, CHARLES A. WELLINa -TON, of Lexingtomin the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Open-Grate Stoves, of which the following is a full, clear, and exact description, reference being had to the accompan ying drawings, forming a part of this specification, in explaining its nature, in which Figure 1 is a view in perspective of a stove containing the features of myinvention. Fig. 2 is a view in perspective of the grate. Fig. 3 is a vertical central section of the stove. Fig. 4 is a horizontal section on the line y y of Fig. 3. Fig. 5 is a horizontal section on the line z z of Fig. 3. Fig. 6 is a view in perspec: tive of the back portion ofthe stove, showing the outer casing removed. Fig. 7 is a front elevation of thestove, representing the doors or sliding plates, hereinafter described, very nearly closed. "Fig. 8 represents in perspec- 'tive the damper and attachments for operating the same. i

The invention relates to various details of construction, all of which are hereinafter more fully described;

Referring to the drawings, A represents the ash-pit, B the fire-pot, C the combustionchamber. The ash-pit is made high and deep, to provide room or space for the large ash-pan a, the side and top edges of which, when in position in the-ash-pit chamber, are outside combustion.

The grate E, preferably,-is cast in one piece and has the flat grated portion or bottom 6 and the curved grated front e, which is shaped and bears the relation to the flat section, shown in the drawings in Fig. 2. a It is pivoted by the pivots or lugs e to the side plates, a so that the Serial No. 135,094. (No model.)

front portion of the grate may be moved upward and inward,and the rear. portion down ward, in dumping its contents into the ash pan or'pit, and the ash pan and pit are made deep enough to receive the full contents of the grate when dumped into itiu this manner. 'When the .grate is in its normal position, its front edge,

6, comes in contact with the curved metal rail or bare" and fits very snugly along its entire edge thereto. The grate also has a hole, 6, in its front edge for the receptionof a poker-handle or any other device for lifting and'dump ing the same, and the curved metal rail is cut railE also serves as asupport for the combos tion-chamber doors G G, and it hasa narrow groove, 9, by which their lower edge is guided. Their upper edge projects into ,a deeper recess, g, in the under surface of the hood H.

These sliding doors or.sections are movable through slots or holes in the wings F back: ward upon suitable guides 01 supports, 9 and when not in use the entire front of the combustion-chamber is open or exposed, as in any open-grate stove; but when moved forward or closed they act to close the combustion-chamher and convert the stove, in connection with the closed front plates, F F, into a close stove; or they may be simply used as a blower. The hood projects well out from the upper portion of the casing of the stove, and sufficiently to form a cover to the combustion-chamber extending over the outer edge of the-grate.

The side and rear casing of the stove is made of iron, and there is a flue, h, between the rear wall of the combustion-chamber and the back portionof the casing, which connects the ash-pit space with the combustion-chamber,

the flue being covered by a perforated ash or coal guard, 12.

The side and rear casing may be cast in one or more pieces, and the lateral extensions or wings F furnish a support for tile or ornamental panels. F represents the hearth, which preferably is of the same width as the frame and extensions.

A damper, M, is arranged in the direct escape-port 'm of the stove, which opens from the rear wall, near its top. This damper, preferably, is so shaped and pivoted that its lower portion, in, moves outwardly, and its upper portion, or, inwardly, as I find by this arrangement a quicker escape for the smoke and gases is provided. It has also a stop, in, against which the upper edge comes in contact and prevents the damper from being shut tightly, there being always a narrow opening along the under surface thereof.

The damper is operated by means of a lever or handle, at, pivoted to a rod, of, which extends through the hood and carries at its lower end an arm, in, whose end is connected with the upperportion of the damper by means of a link, m". The side and rear portions of the stove,when it is not used as afire-place and inclosed by a wall,are covered with a metal casing, N, in a manner to provide the air-space a about the casing, and this shell is provided with the perforations and holes a, by which the air which enters through the lower end of the fines and becomes heated may escape into the room. The top of the outer casing is preferably lifted sufficiently from the remainder of the casing to provide a narrow slit on the front side and baclgif desired, through which the heated air can escape. This casing is fastened to the body of the stove by bolts,or in any other desirable way.

Each of the doors or sliding sections has at its inner end a lug or stop, 0, for limiting the extent of its outward movement.

The plate D preferably has holes extending from the groovefdownward and the full width of the groove, through which ashes or coal or other obstacles may escape or drop upon the movement of the lower edge of the plates therein, so that the movement of the plates shall not be interfered with. The ash-pan may project or extend forward sufficiently to come under these holes, if (lCSllGtl,S0 that the ashes or coal shall be pushed or fall directly into it. The groove 9 in the bar or rail E preferal ily or substantially the same plane as the lower surface of the groove, in order that the ashes, coal, or any obstacles may be easily thrown from the groove by the movement ofthc plates. The upper groove, should be considerably deep, and the doors when not heated must not till it, for it is necessary to provide sufficient space for the upward expansion of the doors, when heated, to permit of their being moved when in an expanded condition.

It will be seen that by arranging the grate so that it dumps inwardly the ashes and coal are thrown backward, and that therefore ashes and dust are not so likely to escape into the groove; also, that the lower doors may be closed and the upper doors almost entirely closed, and still the grate can be dumped, as a space not wider than the poker or device used for lifting the grate between the front door is all that is necessary to provide for the dumping operation, if desired.

. Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States The combination, in an open-grate stove or fire-place,of the grate A, having a carved outwardlyextending front section, the metal rail 0, having the curved guiding-groove in its upper surface and the curved guiding-groove f in its under surface, the plate D,having the curved guiding-groove f, the hood If, arranged to extend outwardly from the frame of the stove and having the curved guiding-groove g, the curved plates G G, movable on a circular path within the side walls of the lire-place to expose the full width of the combustionchamber,the guides or supports 9" for said plates, formed in continuation of the guiding-grooves y g, the curved plates F 1 arranged to be moved upon the are of a circle, and supported when opened by the guides f, and when closed by the grooves ff, substantially as and for the purposes described.
