SPECIFICATION forming part of Letters Patent No. 309,4:29, dated December 16, 1884:.

Application filed April 1854. (X0 model.)

Be it known that I, ELIZABIEITII Noon, of Evansville, in the county of Vanderburgh and State of Indiana, have invented certain new and useful Improvements in Grate Attach ments; and I do hereby declare that the following isa full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

The object of this invention is to apply at the throat of an open chimney-flue sliding doors, the flue being constructed to admit of such doors being moved laterally and horizontally free from the flue-space of an open grate.

ll am aware thatit is not new to use sliding dampers or registers in the throat of a chim-- ncy-tluc immediately above an open grate; but such devices necessarily involve frames, which are obstructions to the free escape of the products of combustion at all times.

In the drawings hereto annexed, Figure 1 is a front'vicw of an open grate eipiipped with my improvcnient, showing the sameprcvious to the ornamental grate-front and mantel having been placed in position. Fig. 2 is a vertical sectional view taken on the line a: a" in Fig. 1. Fig. is a plan view of the attachments, showing the samewith the slide-doors open; and Fig. a is a sectional view on the line j/ y in Fig.

The same letters refer to all the figures.

A in the drawings refers to the frame of the attachments, which is composed of two rectangular frames, 13 B, which are connected at their corners and upper and lower edges by lugs G O, that leave sufiicient space between the frames to accommodate a pair of sliding doors, D D, which are provided near their inner edges with recesses E, to receive the point of a poker or other instrument by means be conveniently manipulated. The inner or adjoining edges of the doors D are provided with flanges F,. serving to prevent any possibility of displacement of the doors when they are opened to their full extent.

the same parts in G designates the grate, and H the chimney.

I11 practice the frame A is set in the chimney above the grate before the ornamental front of the latter and the mantel-shelf are placed in position in such a may be opened laterally under the mantelshelf, and so that when closed they shall con1- pletely close the chimney-opening.

The operation of this invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed.

When during cold weather the grate is not in use, the doors 1) I) may be closed, so as to prevent cold air from entering through the chimney.

At all seasons when the grate is not in use the doors D, when closed, will prevent soot and dirt from dropping upon the hearth.

\Vhen the to be-opened, and by opening them more or less they will serve to some extent to regulate the draft.

It will be seen by reference to Figs. 3 and i that the doors 1) D can be moved inside of the sides of the chimney-jamb, and thus leave a free space the entire width of and height of the flue-throat.

i am aware that it is not new in fire-places to employ, in combination with chimney-flues, a series of slots at the bottom thereof, provided with removable dampers, and therefore I do not claim such a device. By my invention I am able to employ laterally-sliding dampers, and to leave a free, unobstructed space equal to the full horizontal area of the flue when said dampers are fully opened.

I am also aware that it is not new to employ laterally-sliding doors in a frame'located in the line, which is recessed to receive said frame.

I claim as my invention and desire to secure by Letters Patent 1. The combination, with an open fire-grate, of a chimney which is provided with recesses, the sliding doorsD D, the frame B, constructed of two parts united by lugs C, and the stop flanges F, all constructed and adapted to operate substantially as and for the purposes described.

2. The combination of the open frame 13,

constructed of two parts united by corner lugs,

3. The combination, with the laterally-slid 7 ing doors having flanges and recesses as de- ELIZABETH XVOOD. scribed, of a frame composed of parallel open plates united by means of lugs C O, and adapt- W'itnessesa l ed for application to the throat of a chimney, i ALVAH J OHNSON,

as specified. JAMES B. RUoKER.
