CHllVlNEY CAP AND PROTECTOR.

SPECIFICATION forming part of Letters Patent No. 399,594, dated March 12, 1889.

Application filed May 18, 1888! Serial No. 274,312 (No model.)

To (ZZZ whom, it may concern:

Be it known that I, \VILLIAM W. WRIGHT,

a citizen of the United States, residing at 1 Yllllllk, in the county of Erie and State of i hand engaging theopenings 1", thus securing the hood to the main plate.

New York, have invented new and useful Improvements in Chimney Caps and Protectors, of which the following is a specification.

The invention relates to improvements in chimney caps and protectors; and it consists in the construction and novel combination of parts, hereinafter described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

Figure 1 of the drawings represents a perspective view of the cap detached. Fig. 2 represents a central vertical longitudinal section of the same in place on top of a chimney. Fig. 3 represents a plan view of the lower section of the cap. Fig. i represents areversed plan view of the upper section of the cap. Fig. is a perspective view of the cap having amodifled shape.

Referring to the drawings by letter, A designates a chimi'iey-top, and B designates the cap thereon.

O is the main plate of the cap, exactly fltting upon the top of the chimney, having the depending flange c, which surrounds said top for any desired distance downward, and the depending flange c, surrounding its central opening, 0 fitting exactly within the chimney-opening, and projecting a necessary distance within the latter to hold the section in place.

I) is a vertical. protecting-flange surrounding the central opening of the main plate and projecting upward therefrom a necessary distance.

E F are lugs standing upward at equal distances from the centers of the end portions of said flange D, and connected to said portions by the reenforcing ribs j, which prevent the lugs breaking easily from the plate 0. The said lugs are provided at corresponding points with the bolt-opcningsj, Fig. 2.

G designates the hood, arranged over the main plate and provided with the flange g, depending from its edge and resting upon the said plate. The said flange is provided with notches or outlet-openin r in its lower edge, which lower edge is equally distant at all points from the central opening of the main plate,

E and has in its ends the openings 71, register- 1 ing with the bolt-openings f in the lugs F,

against which the ends of the flange {7 rest.

ll Hare bolts passing through the openings I is a deflecting-flange depending from the inner surface of the roof of the cap, which flange somewhat wider than the flange l), projecting from the plate t, and i t' are openings in the roof of the upper section around the deflecting-flange I.

The smoke and other products of combustion from the chimney pass through the opening in the main plate, are deflected by the central solid portion of the cap, and thence pass out through the openings 2'. On the other hand, the rain, which may enter through the openings i, is deflected by the flange I and caused to fall on the main plate around the flange 1), from whence it flows outward through the notches or outlet openings g and drips from the points which are formed on the lower edge of the flange 0. This flange is preferably inclined outward toward its lower edge, so that the points 0 are removed from the faces of the chimney, whereby the drippings will drop clear of the latter, and therefore will not deface the same.

The flange D prevents the water from entering the mouth. of the chamber, and the flange I, being larger than the flange D, sheds its water outside the latter upon the roof of the lower section. Thus a perfect exit is provided for the smoke and no water is permitted to enter the mouth of the chimney.

Fi g. 5 represents a modified form of the chimney-cap, in which the forms of the parts are somewhat modified, but without changing the operation in any way.

Having described my invention, I claim 1. In a chimney-cap consisting of the main plate having a central opening and provided and providedwith apertures 01, which are over the inclosed portion of the main plate, substantially as specified.

2. A chimney-cap comprising the main plate having a central opening and provided with a circumferential flange, c, the hood arranged over the plate and provided with a depending flange resting on the main plate around its opening and removed some distance therefrom, and the deflecting-flange I, larger than the opening in the main plate and depending from the top of the hood, the portion of the top of the hood inclosed by this flange being solid, while the portion around the flange is provided with openings 1', substantially as specified.

3. In a chimney-cap, the main plate 0, having a central opening, 0 and provided with the depending flanges c and 0, and the vertical protecting-flange D, standing up around the central opening in the plate, in combination with the hood G, fitting over the main plate and provided with the depending flange g, bearing on the plate between the central opening and the outer edge and provided with notches or outlet-openings g g, and the defleeting-flange I, depending from the top of the hood, with its lower edge arranged ,over the portion of the main plate between the flanges D and g, the top of the hood being solid within the deflecting-flange I, and provided with openings 2' i around the same, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
