I i '-+a TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIAM A. GREENE, of Troy, in the county of Rcnsselaer, and State of New York, have invented certain new and useful improvements in Cool;-Sto\'es j. and I do hereby declare that the following is a full, clear, and exact description oi the construction and operation oi the same, reference being had to the annexed drawings, and to the letters of reference marked thereon, forming part of this specification, in w.hich

Figure 1 is a perspective view; and

Figure 2 is a longitudinal vertical section-- The same letters referring to like parts in each of said figures.

The nature of my said invention and im 'n'ovements consists in combinin with an oven-front plate of cool stoves an angular detachable shelf-plate, so constructed as to form, relatively with said oven-front plate, a hollow shelf-plate, for protecting the exposed part of said oven-platc at and below the fire-grate from the great heat of the fire; also for the purpose of supporting the back part of the gratcbed plate and fire-plate or fire-brick, in manner substantially as hereinafter fully shown. It also consists in the relative construction and arrangement in a cook-stove of a portable ash-box, and its pit or seat, in such respect to each other as to be operated so that ashes or clinkers maybe dumped from a fire-grate directly into said ash-box without the aid of any intervening device for conveying ashes to said ash-box; and said ash-box can be readily and conveniently moved forward, so as to be lifted up out of the pit through the space which is covered by the hearth-plate from its seat when its contents are to be discharged, all substantially in manner as hereinafter fully described.

To enable others sltilled in the art to make and use my said invention and improvements, I will proceed to describe the construction and use of the same.

A, figs. 1 and 2,'represents the even of a cool;stovc, and B shows the front plate of said oven. Arranged back of and below the firc-grate U is a shelf-plate, a, which is so constructed and arranged in direct combination with said frontplate B as to form a chamber or a hollow shelf-plate between the oven A and the fire-box. Openings 0 are made through the side plates of the stove to admit cold air into this chamber. This hollow shelf-plate is for the purpose of protecting that particular part of the oven-front plate situated directly back of and just below the fire-grate from rapid burning out or wearing away by the strong heat of the fire. Cold air circulating through said hollow shelf-plate by means of the openings 0 prevents extreme heat from reaching that part of the said oven-plate; thus the oven-plate is protected, while the aforesaid hollow shelf'plate receivesv the strong heat instead; and when said shelf-plate is burned out it is easily removed, and a new plate is substituted without dismounting the stove or displacing the oven-front plate, and it is done at little expense in comparison with the cost of repairing a stove with the old pattern of oven-front plate, which, when burned out only in that part, the whole plate has to be removed, and an entire new plate substituted, which can only be done by dismounting and remounting the stove in order to do so. D is a portable ash-box, provided with a rigid or standing handle, 0, extending lengthwise with and is attached to the respective ends of said ash-box. The front upper part of this ash-box is constructed with a projecting lip,f, projecting from the box, in manner sub stantially as shown in the annexed drawings; and aflixed to the back side may be a handle to aid in dumping ashes from said ash-box also an ash-sifter may be added to the said ash-box if desired. E is a pit or seat, constructed in the front part of the stove, and is for this ash-box to rest and operate in when in use. This pit or seat is made about one-third wider than the aforesaid ash-box, or it is as much wider as will admit of the said ash-box being drawn forward suiliciently to allow of its being readily lifted out of said pit by means of its handle. The upper front part 5/ of said pit is made to incline or slope inward towards the pit, in manner substantially as shown in the annexed drawings. The dotted lines in fig. 2 represent the ash-b0x as drawn forward in its pit in readiness to be lifted therefrom in order that ashes may be dumped from the box. The act of drawing the ash-box forward causes the projecting lip f to ride upon the inclined part 9 of the pit or hearth, which causes the front part of the ash-box to rise, and thus places itin a canted or inclined position, such as to admit of said box being most readily lifted out of said pit, the handle of said ash-box being always in position for use, and it is kept from getting hot by currents of cold air pass'inp, through the draught-register holes in the hearth-plate, and circulating over and under said handle.

The advantages gained by my improvements in cook-stoves, above described, are as follows: By making the oven-front plate in one entire piece, and protecting those parts most liable to burn out at and below the l fire-grate by means of the aforesaid hollow shelf-plate, I obviate the nuisance of fine ashes getting from the, fire-box through into the oven, which would occur more or less through joints in the old pattern of oven-front plate. An important advantage is gained also in lessening the expense of repairing oven-front plates, in manner as hereinbefore mentioned. A further advantage is gained by having the fire-grate to dump directly into the ash-box without the aid of any intermediate device for conveying ashes: thereto, as ashes will, or are very apt to lodge on such devices, and have to be raked oil into the ash-box by means of a poker, to do. which necessitates the opening of fire-doors, or of removing hearth-plates, thus allowing fine ashes to escape into .the room. This objection I entirely remove. As my improved construction and arrangement of ash-box and its seat admit of as hes being dumped atonce and completely'into the ash-box, no lodgment of ashes can occur, consequently no raking oil is required; hence the ash-box and itspit may be tightly enclosed, and remain so while ashes are dumped and settled into the ash-box. No ashes can escape into the room during said operation. I am aware that hollow spaces, or flue-ways, or air-chambers between the oven front and fire-box back plate, from the grate upward, for admitting air to the upper part of the fire-box, have been used in public for years. I also am aware that a double back, or tubes answering thereto, have been extended up from the bottom f of the ash-pit for the purpose of supplying. air, or for other purposes. But my improvement for supporting the back edge of the grate is not a flue, nor is it a channel or medium for supplying air to the fire-box. It is for the purpose of protecting the oven-front plate at the back edge, and below the grate only a short distance, thus leaving the remainder of the lower part of the oven-front plate single, and capable of receiving and radiating the heat into the oven. If the plate were made double down from the grate to the ash-pit the conduetion of heat and radiation thereof into the oven at a point between the grate and bottom plate of the oven would be but imperfect. In the patent granted to Samuel Smith, November 29, 1859, a hollow back, provided" with zigzag passages to supply air to the fire-chamber through hollowgrated bars and plates connected therewith, is employed. I do not claim any such construction as my invention. I also am aware that an ash-box arranged snugly in an ash-pit partly under the grate, so as to receive the ashes directly therefrom, is .not new, and that an ash-box with a'bail, and arranged to slide'out through a front door, has been devised; but I lay no claim to such construction as my invention; but I do believe that it is new to construct the ash-pit wider than the ash-box, so that thelatter may be moved wholly under the grate so that the ashes from every part of the grate may fall directly into it. l belierc it is new to have the extension f on the ash-box and Ith'c'inclined plane 9 on the front of the ash-pit, so that the ash-box may be drawn forward far enough to be conveniently lifted up by the bail out of the pit when the hearth-plate G is removed. I further believe that it is new in Cufk nection with this-construction and arrangement to provide for keeping the bail cool, as I have set forth.

Having fully described my improvements in cook-stoves, whatI claim as my invention, and desire to secure by Letters Patent, is-

1."'I"elaim, in combinationwith "an oven-front plate, a shelf-plate, so constructed and arranged in respect to said oven-plate as to form in connection therewith a hollow shelf-plate, substantially as end for the purposes set forth. V i

2. The detachable shallow shelf-plate a, applied below the grate and above the ash-box, in combination with the front-oven plate B and the perforated side plates F, substantially in the. manner and for the purposes herein described.

3. The angular shelf-plate a, substantially as and for the purposes described.
