HOOD FOR FIRE-PLACES.

SPECIFICATION forming part of Letters Patent No. 449,347, dated March 31, 1891.

Application filed October 31, 1890: Serial No. 369,967. (No model.)

T0 to whom it may concern:

Be it known that I, LEONARD E. CLAWSON, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Hoods for Fire-Places; and I hereby declare the following to be afull, clear, and exact description of the same.

My invention relates to anovel attachment which I call a hood for fire-places and grates.

It consists of a hollow adjustable casing which is adapted to fit into the upper part of the grate-opening, and in certain details of construction, which will be more fully described by reference to the accompanying drawings, in which Figure 1 is an exterior view of the head. Fig. 2 is a view of the interior from the reverse side. Fig. 3 shows its application to a grate.

Considerable difiiculty is experienced in the use of fire-places and grates on account of the tendency of the smoke to puff out into the room, and this is overcome by the use of a hood fixed in the upper part of the front of the fire-place or grate. It consists of two metallic plates A A, curved, as shown, and having the flanges B at the top and at the ends, the ends of the sections A being also closed, as shown, or, if desired, these ends may be left open, and when adjusted in the fire-place or chimney the sides of the fire-place will form the closing ends. The lower portion of this device is left open, the lower edges of the curved plates A not extending as far back as the upper edges. One of these plates is made sufficiently larger than the other so that it may overlap and telescope upon the other, as shown at C, Fig. 2. Longitudinally through the center and rear portion extend the rods D, the outer ends of which are secured to the end plates 13, and the inner adjacent ends of these rods are screw threaded and pass through a turn'buckle or device E, by which they may be lengthened or shortened.

F are guides and supports extending vertically downward from the top plates B, having their lower ends attached to the overlapping adjustable rods G, and these vertical guides F serve to support the inner ends of the rods D.

It will be manifest from this construction that the sections A may be made of any suit= able length approximating to the width of the grates or fire-places where the device may be used, and it will not be necessary to fit it exactly to any particular width.

In applying the device the turn-buckle E is turned so as to draw the ends toward each other until the length of the device is less than the width of the grate-opening or fireplace where it is to be employed. It is then introduced into the upper part of the grateopening, as shown in Fig. 3, with the upper edge extending inside of the grate-front H, and the turn-buckle E is turned around so as to force the rods D and the sections A, to which they are attached, outward until the ends of the sections bind firmly against the interior of the grate or fire-place, where the device will be held without any further fast a ening.

The lower and outwardly-arched portions of the plates A project outwardly from the grate front and then curve inwardly toward it again, and the device fills the upper portion of the grate-front, so as to close the opening to a point nearer the fire which is in the grate. This improves the draft of the chimney and causes the smoke to pass upward more directly, and any eddy or blast which is caused by the wind, and which would tend to throw the smoke outward into the room, will cause it to follow the interior curves of the front A A, and the smoke will thus be again directed into the chimney, so as to pass upward and not be allowed to come out into the room.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A hood attachment for grates and fireplaces, consisting of the overlapping sections having the top and end flanges B and an open bot-tom, the overlaping adjustable rods G, and the threaded rods and turn-buckle for adj ustably securing the sections, substantially as herein described.

2. A hood for grates and fire-places, consisting' of the sections A, adapted to telescope upon each other, and the rods extending within said sections having the turn-buckle or device whereby they may be extended so as to cause the ends of the sections to bind within the grate or fire-place, substantially as herein described. 7

In witness whereof I have hereuntoset my hand.

LEONARD E. cLA'wsoN.
