CHIMNEY T-OP AND COWL.

SPECIFICATION forming part of Letters Patent No. 243,133, dated June 21, 1881.

. Appncation niet Apn'i 13, 1881. (Model.)

To all whom it may concern:

. Beit known that we,LENERD HEss and J A- COB F. HEss, ofMassillon, in the county of Stark and State of Ohio, have invented certain new and useful Improvementsin Chimney Tops and Oowls and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had tothe accompanying drawings, and to letters of reference marked thereomwhich form a part of this speciication.

Our invention relates to an improvement in chimney cowls and tops and it consists in certain details in construction and combinations of parts, as will be more fully explained, and pointed out in. the claims.

In the accompanying drawings, Figure l is a perspective view of our improved device. Fig. 2 is a longitudinal section, and Fig. 3 is a detail view of the annular ring and supportl ing-arms and spindle to which the hood is attached. Fig. 4 is a detached plan view of the blank from which the hood is made.

A represents the bottom or base of the top, which can be made of any design and contiguration to conform to the shape ofthe chimney, and provided with a flange, a, formed at the top thereof, around which the body B ts, and is secured thereto by screws or rivets, with the lower end of said body resting on the top a of the base A.

D is an annular rim fitting on top of the body B, having a depending flange, d, around which the top of body lits, said annular rim being rigidly secured to the body B by screws or rivets passing through the body and llange. Rim D is provided with any suitable number of inclined arms or standards, d', cast solid therewith and projecting upward and inward from the interiorofsaid rim, wh ere they unite to form a bearing, d2, directly over the center of the chimney, adapted to hold the spindle carrying the hood in an upright-position and allowing same to revolve freely.

E is a cross-bar running transversely across the chimney, and secured at its ends to the metallic rim D by bolts or rivets. Thisbar is provided with a pivot, c, which lies directly below the bearing formed by the `juncture of the arms d', on which the lower end of the spindle F, which is counter-sunk for the purpose, rests, the spindle being retained in place by the pin f inserted through a hole just below the ring or bearing d2, above described.

The spindle F is provided at its upper end with wings or projections j", made integral with or separate therefrom, as desired, said win gs being adapted to receive and retain the hood or cap G by the rivets g passing through same. used, and are so bent and shaped as to conform to theinternal configuration of the hood, which in the present instance is made from a round piece of metal with a V-shaped piece cut therefrom, the cut ends being brought together, secured by riveting, and so bent that its long diameter will always be in line with the direction of the wind, and be retained therein by the feat-her H, secured to the top thereof.

Any number of these wings may be A hood constructed as above described is well adapted to high winds, as the oblong construction thereof is sufficient of itself to keep the hood in position, and the peculiar and gradual inclination of its sides and the strengthening ribs or wings f prevent the same from collapsing and becoming distorted by the pressure, as is seen in a great many devices now in use.

The rim D with the hood can be used on any chimney or smoke-stack of any construction whatever, as the rim can be oblong or rectangular, as well as round, to suit the design of the chimney on which itis to be placed. When it is desired to use it on chimneys constructed of masonry, an annular lian ge runnin g outward at right angles to the rim can be constructed with said rim D, on which one or two courses of bricks can be laid, which will effectually hold the same in position.

When the base A is used in connection with the other parts, it can be set over the top of the chimney with its lower edge projecting over and around the top thereof, or can be provided with a liange on which the last one or two courses of brick can be laid, which securely holds the whole structure in position.

Instead of having the cross-bar constructed as described to form a bearing for the lower end of the spindle, said bearing can be formed by arms projecting from the inclined arms and IDO converging toward the center, and provided with a pivot similar to that described for the cross-bar.

It is evident that slight changes in the construction of our improved top and cowl might be resorted to without departing from the spirit of our invention, and hence We would have it understood that we do not confine ourselves to the exact construction shown, but consider ourselves at liberty to make such changes as come within the spirit and scope of our invention.

Having fully described our invention,what we claim as new, and desire to secure by Letters Patent, is-

l. In a chimney top or cowl, the combination, with the rim having inclined arms formed integral therewith, said arms forming a sup- Y port for the spindle carrying the hood and a bearing for the lower end of said spindle, of a spindle having wings formed integral therewith or separate therefrom, the said spindle being adapted to receive and retain the cowl,

- substantially as set forth.

2. A hood for chimneycowls constructed from a round piece of metal having a V-shaped piece cut therefrom ,the cut ed ges bein g brought together and secured by rivets, substantially as set forth.

3. In a chimney top and cowl, the combination, with the base and body and rim, constructed as described, and cross-bar, of aspindie having wings extending therefrom adapted to receive a hood, said spindle and hood being supported and held in position by the inclined arms and cross-bar, substantially as set forth.

In testimony that we claim the foregoing we have hereunto set our hands this 31st day of March, 1881.
