Y V o, UQUHVV" *mw COOK- STOVE i ll 0 82 4 0 K' PATENTED OCT 11 1870 dilated gitane' WILLIAM C..DAVIS,'OF CINCINNATI, OHIO.

Letters Patent No. 108,240, dated October 1l, 1870.

The Schedule referred tc in theserLetters Patent and making part o. the same I, WILLIAM C. Davis, of Cincinnati, Hamilton county, Ohio, have invented' a new and useful Improvement in (look-Stoves, of which the following is a specification.

Nature mul Objects of the I nrenton.

The use of bituminous coal as fuel in cook-stoves having suggested the necessity of sonic means ol' 'ready discharge ofthe cindcrs and ashes, various forms of shaking and dumping-gratos have been proposed, but none of them, so far as known, fully accomplishing the .object of prompt and complete discharge of the contents. 1t is also found to be necessary to present a form of grate that shall oppose no obstruction to the stirring-action of an ordinary hook or poker, and one ,that shall afford, by its height of open grating below the breast-plate, an ample incandescent surface for the purposes of toasting, roasting, &c.

My invention relates to a construction of forwnrddumping grate, combiningI the above-recited advantages wth those of complete closure of the lire-front, when necessary, thelatter object being accomplished by the pl'ovision of a suitable protuberanc, or bouncted projection, from the front plate| ot' the stove,

such as to enable the forward dumping ot' the grate, and the complete shutting in of the same, so as to prevent the escape ofdustand ashes into the room.

General Description wilh reference to thc Drawing.

Figure 'l is a perspective view of a eookinglstove embodying my improvements, the warm shelf being attached and the fire-door being open.

Figure 2 is a longitudinal section of the front part ofsaid stove.

Figure 3 shows the ash-pan and lifter, detached.

Figure 4 is a transverse section of the warmingshelf, together with contiguous portions of the top and side' plates.

A represents the front plate;

B, the jambs or side plates; and

C, the top plate of my cook-stove.

'lhe mouth or opening-of the front plate is inclosed, around its top and sides, by a bonnet or projection, D, whose front .edge slopes obliquely forward and -downward,'and is provided with a door, E, by which, in conjunction with the hearth-plate F, (which closes the ash-pit and the lower margin of the bounet,) the entire lire-chamber and ash-pit may be inclosed or shut in whenever itis desired to empt-ythe grate or to arrest the ingress of draught air to the stove.

The form and dimensions of the bonnet and heartilplate and bonnet `are clearly represented iu figs. 1 and 2, and are such as, in addition to the objeetsjust recited, to enable the forward dumping of a high liregrate, G, such as is here shown in its normal position in tig. l, and in its discharging or dumping position.in iig. 2.

The grate is suspended by trunnions H, occupying bearings I in the stove-jambe, and one or both terminating in a square or other suitable head, h, to take the corresponding eye j of a wrench, J, which, having a l|ook,j, at its other extremity, may serve also as an ordinary lifter. The trmmions H are so located on the grate as te enable the latter to remain securely in its normal position, save when forcibly removed therefrom by the action of the wrench; and said trunnions may be so located as to either cause the said grate to retain its dumped position unt-il purposely restored to its normal position, or to automatically return to said position by its own weight.

The said grate is preferably composed of a congeries of Uforme`d bars, in planes parallel to the stovejmnbs,-'nnd having no horizontal bar or parting other than the two terminal bars y g', so as to afford no obstruction to the descending ashes, or to the actionof a poker or stirrer, and also to afford the greatest possible radiating incandescent surface for toasting or roasting.

I aux aware that gratos of cook-stovcs have been made to dump rearwardly against the oven-plate or fire-back, but such devices are imperfect and objectionable, owing to the limited passage permitted or attainable for the descending debris.

I am also aware that gratos of cook-stoves have been adapted to dump forward, but such gratos have been objectionable or practically useless, owing to their very limited height, and other defects of construction.

K represents a rack or perloratedjhelf, adapted to be aflixed to the stove-top, as represented, so as to form a continuation of said top, onto which shelf pots or other vessels may bc shifted froln the stove-top, when desired to be kept warm, without further cooking.

In older to utilize the ascending air which has been .heated by contact with the stove sides, I make my said shelll in the represented open or perforated forni; and that it may be easily attached to or detached from the stove, there project from the under, side ot' the shelf two or more brackets, L, which, engaging under the down-turned flange of the top plate, in the manner shown, bears against the jamh.

A series of screw-bolts, M, depending through holes in the top plate, outside of the jambs, and extending through said bracketsfare provided with nuts N which serve to hold the shelf in place.

The said shelf is preferably perforated, andtiush with thc stove-top, .for the objects stated.

For the purpose of convenient handling without soiling of the fingers, the ash-pan U has cast on, anu combination with the bonneted projection D and door v projecting from its inner side or sides, one or more E, and hearth-plate. F, substantially as and for tho ears, 1, which enable the pan to be lifted by means objects set forth.

of n. lifter, which may be thefsamc combined wrench In testimony of which invention, I hereunto set mv nml iii'ter J which is employed to operate the grnto hund. and the stove-lids. WILLIAM C. DAVIS.
