J WISDOM SMOKE DEFLEGTQB. No. 444,967.

" UNITED STATES JOHN ISDOM, OF CHICAGO, ILLINOIS.
PATENT OFFICE.-
SMOKE-DEFLECTOR.
SPECIFICATION forming part of Letters Patent No. 444,967, dated January 20, 1891.
Application filed March 3 1890.
To all whom it may concern:
Be it known that I, JOHN IVISDOM, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented new and useful Improvements in Smoke-Deflectors, of which the following is a specification, reference being had to the accompanying drawings, illustrating the invention, in which Figure 1 is a face view of the adjustable fire-board portion of the invention; Fig. 2, a vertical sectional elevation of the fire-board, its frame, and the smoke-deflector in position in a fire-place, taken 011 line X, Fig. 1. Fig. 3, an enlarged view of the smoke-deflectorand the upper portion of the same parts shown at Fig. 2; Fig. 4, a back side elevation of one end of the smoke-deflector enlarged; Fig. 5, a
broken elevation of the inside of aportion of.
one of the frames which support the adj nstable fire-boards, showing two of the springs which hold the fire-board plates in position, the same being full size; Fig. 6, a top View of one of the frame-pieces which support the fire-board with the ends of the fire-boards therein, they having a size corresponding to Fig. 3. Fig. 7 shows how the meeting edges of the fireboards overlap, full size.
This invention relates to an adjustable flreboard which operates in conjunction with a smoke-deflector adjustably attached to the frame of the fire-board that it may be extended upward to form such a throat to the chimney as will insure a proper draft when the fire-board is elevated.
The nature of the invention will be fully understood by the following detail description.
R represents an ordinary fire-place, and N is the breast of the same, and O is the back of the chimney. I employ two metal framepieces A, which are made in pairs, and their jamb sides are inclined inward, as shown at Fig. 6, that they may be wedged firmly in between the jambs of the fire-place and shut out any gas and smoke which might otherwise escape into the room. In the inner faces of these two frame pieces, respectively, are formed three grooves J I S, and in the grooves Serial No. 342,372. (No model.)
8 are firmly affixed what I term a breastplate? B, which lies wholly in front of the adjustable fire-boards G D. The latter are fitted to run, respectively, in the grooves I J. The tire-boards are preferably made of about No. 1'2 steel plate. The upper edge of the upper plate is bent outward to meet the inner lower portion of the breastplate, as shown at F, Fig. The lower portions I of the grooves I are filled with stops P, that the top edge of plate C may not come below the breast-plate l3, and the meeting edges of the plates 0 D are provided with bent overlapping portions 1) b, that the fire-board at that place may be dust-tight. Springs g g, made of rolled brass, are riveted to the sides of each plates 0 D, near its ends, to bear against the separatingribs en, and serve as friction-supports to hold the plates up in any position desired. In practice the grooves will be about threeeighths of an inch deep and the springs at each end of the plates of the same width. This will be fully sufficient for the purpose.
The smoke-deflector consists of a single stiff plate of metal formed with ends K, which. incline inward from the jambs of the chimney, and a back portion L, which pitches back toward the throat thereof. The ends are provided with flat portions M, which are parallel to each other and provided, respectively, with slots a a, through which screws a are to be put to hold the deflector to the inside edges of the frame-pieces A. By loosening the screws the deflector may be adjusted to bring the plate L to a height corresponding to the throat. In the construction shown the throat is so high that the portion L has to extend above the ends K. The extension, however, does not prevent the same deflector from being lowered down and employed in fire-places Whose threats are lower down. This deflects the smoke from contact with the under side of the breast N and prevents it from coming into the room, and by the use of these devices almost all fanlty fire-places can be made to have sufficient draft by lessening the size of the throat and air-supply, thus making a small chimney or short one serve a good pur-= pose.
I claim and desire to secure by Letters P-(itprovided with ends which are also inclined ent of the United Statesinward to fit the jmnbs to deflect smoke, as xo In adjustable fire-board fronts for the specified. places, the side vertical frame-pieces of such T 5 front inclined inward t0 lit the jambs of the JOHN WISDOM fire-place, in combination with a smoke-(le- \Vitnesses: fleet-0r which is adjnstably secured to the end ANNA D JOHNSON,
frame-pieces, inclined back from them, and e G. L. CHAPIN.
