DANIEL STONR AND JOSEPH STONER, OF WEST OVERTON, PENNSYL- VANIA.

IMPROVEMENT iN Fles-PLACES.

Specification forming part of Letters Patent No. 42,804, dated Muy 17, 1864.

To all whom/,it may concern;

` Be it known that we, D. STONER and J.

STONER, both of West Overton, in the county of Westmoreland and State of Pennsylvania,

, have invented a new .and Improved Grate; v and We do hereby declare that vthe following is 'a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part ot' this specification, in which- Figure l represents a transverse vertical section of our invention. Fig.v 2 is a front elevation of the same. Fig. 3 is a plan or top view of the same.

Similar letters of reference in the three views indicate corresponding parts.

This invention consists in' a damper arranged in front and under the grate, in combination with an adjustable draft-hole, con.

,by means of a rod from the interior of the room or apartment in whichthe grate is situated, in combination with a stationary plate shutting out the supply of air to the under side of the grate from the interior of the room in such a manner 'that the supply of air necessary for the combustion of the fuel in the 'grate can be regulated from the interior of the room or apartment by opening or closing th covering plate or valve.

` The invention finally consists in an ash pit 'provided with a hinged lid or cover on top, and with a door leading to the exterior below,-

in combination with a' grate of the ordinary construction in such a manner that the ashes and cders dropping from the grate can be readily swept down into said ash-pit and removed therefrom and n-o dust or ashes are allowed to pass into the room.

To enable others skilled in the art to make and'use my invention, I will proceedf'to describe it.

A represents a grate consisting` of an ob long frame of cast-iron or any other suitable material, and provided with upright bars a, as clearly shown in Fig. 2 of the drawings, or constructed in any other suitable manner, and applied in combination with the horizontal slatted frame Ait. This grate is set between the upright grooved guide-bars B, which are firmly secured to the inner sides of the cavity C, in-which the grate is built.

D is the hearth, which may be made on a level with the floor of the room or apartment in which the grate is situated, or which may be slightly elevated above said door, it' desirable. The space between the lower edge of the grate A and the topsurface of the hearth is occupied by a plate, E', of metal or other suitable material, which may be permanently tixed between the upright guide-bars or made movable in the same, and thisV plate .formsthe bearing or guide for a rod, a', by means of which the supply of air to the tire on the grate can be regulated.

The air is introduced from the exterior ot the room or building through a pipe, F, which may be made to extend through the rear wall, G, provided the building or room is so situated that such can be done, or which may "extend down to a lower story or out in any convenient direction. This pipe is provided with a sliding covering plate or valve, b, which connects with the rod a', so that it can be opened or closed. by means of said rod, and

the supply of air can be regulated.

The hearth' D is hollow, and access can be had to it through the lid E or through the 4 door 1. The lid E swings on gudgeons, which have their bearings in the sides of the hearth, and when closed it is flush with the upper surface of said hearth. Itis so arranged that it can be readily raised by means of a poker, and the space between its inner edge and the plate E is occupied partly by the cross-bar c and partly bythe damper J. This damper is hung ou gudgeons similar to the lid, and by throwingit open the draft ot' the re in the grate is stopped immediately. By the combination of the damper J and valve b of the pipe F the draft can be regulated to perfection. The door l is situated in the lower part or near the bottom of the ash-pit, and, if possible, it ought to lead tothe exterior of the building, so thatl the ashes from the ash-pit can beremoved inthe most convenient. .man-

ner. In cases where it is impractcable to combination with the draft-hole F,'dnmper J, have the door lend to the outside of the buildand grate A, constructed and operating subing,` the ashes and cinders may also be restanti-.lily as and for the purpose set forth. moved through the lid E. 3. The hearth D, WithjaJ lid, E, anddoor I, Vhat we claim as new, and desire to secure in combination with the gra-te A, constructed by Letters Patent, isf and ope-rating in the manner and for the purl. The combination of' the damper J with pose substantially as specified. the grate A and adjustable (ll-ufr hole u1- plpe DANIEL STONER.
