CHlMNEY-COWL`I ;PECIFICATION forming' part of Letters Patent No. 458,894, dated September 1, 1891.

Application filed September 26, 1890. Serial No. 366.237. (No model.)

T0 all whom, it may concern:

Be it known that I, PERRIS W. GARDNER, a citizen of the United States, residing at Frost, in the couu ty of Navarro and State of Texas, have invented new and useful Improveinents in Chimney-Cowls, of which the following 1s a specification. p

My invention has relation to chimney-ventilators, the purpose thereof being to provide a self-Operating smoke-conductor, especially adapted for use in all windy climates, to be placed over the discharge -openings of the fiues, by which the smoke is carried off, whether the same be of brick, stone, or iron. It is my purpose also to provide asinoke-conductor which shall be automatically reversed or turned by the wind in any and all directions.

The invention consists in the several novel features of construction and new combination of parts hereinafter fully set forth, and then definitely pointed out in the claim following this specification.

To enable others skilled in the art to make and use my said invention, l will proceed to describe the'samein detail,reference being had to the accompanying drawings, in which- Figure 1 is a perspective view showing'` my invention. Fig. 2 is a central Vertical and longitudinal section of the cowl mounted on a chimney of any ordinary construction. i'

In the said drawings the reference-numeral l denotes the chimney having any ordinary 01' preferred construction and within which one or more fiues may have exit.

The reference-numeral 2 denotes the lower section of the fiue, which is seated upon said chimney and covers the ends of all the square or oblong fiues which discharge therein. Upon the lower section is formed or mounted -a central Vertical collar 3, having a yokefrom said standard 9. These brac'es form part of the veniilator, to which they are riveted, and while formin g practically two braces they may be formed, as shown, in a single piecehaving a central opening, through which the pivotal standard 9 passes, a cross-pin be' ing inserted above to prevent the ventilator from being blown off.

Upon the endofthe ventilatoropposite to the pointer S is formed or mounted a wind'vane 12, between which and the standard 9 is the open 01' exit end 13, through which the smoke, heated air, and products of combustion escape in a direction contrary to the pointing of the vane, thereby aifording a valuable protection against fire, inasmuch as the Sparks and other live products of combustion which inay issue from the chimney and which may contain incendiary or indainmable material are driven or drawn out through the opening, preserving the tops of the fiue's covered by the cowl. p

Depending from the ventilator 5 is a collar 3a, engaging the collar 3 on the lower section 2, in order to give a steady pivotal moveinent to the Ventilator. This collar issubstantially concentric with the pivotal standard 9, and both are arranged between the conical closed end and the open or exit end of the ventilator to balance the weight and en able the 'latter to turn freely.

The wiud-vane 12 is arranged substantially in line with the ventilator and is provided with a smoke-opening 13, adjacent to the open or exit end of the ventilator, or, in other words, between the latter and the' solid portion of the vane, to puermit the free passage of the smoke and other products hof combustion as they leave the open end 13 in the line of the Vane or at an angle'thereto. By this constructiou I am enabled to extend the Vane to some distance beyond the open end of the ventilator, and thercby obtain an increased leverage for the Vauc without materially increasing its weight. Moreover, in sudden shifts of the wind the smoke can pass freely through the opening 13, instead of being pressed against the body of the Vane and being driven over or under the latter. I prefer to form a depending fiange upon the lower end of the lower section 2 of a size to surround the exterior of the chimney-top. Vhen IOO a round filie only is used, the Standard-bearing is riveted to the end of the pipe, the lower section 2 being dispensed with; I

It will be readily seen that a bi'eeze from any qnartei* Will direct the conieal end of the Ventillator towand the direotion from which the Wind prooeeds,` and When this takes place the passage of the air aron nd the pivoted ventilator bl'ings the same into a position in which its longitndinal axis is in the line of direotion of the Wind, therebydl'awing the smoke out of the ohirnney, inoreasing the draft, and deoreasing the danger of fire.

What I claiin is- In a ehimney-cowl, the combination, with a lower seetion having a (ollaf,` of aoylin` drieal v'entilator pivotally monn'ted tliet'eon and having a (losed end on one side' and an open or' exit end on the other side of the point of support and provided also With a wind vane ai'ranged in line with the ventilatox` and having' a smoke-'opening adj aeent to said open 01' exit end, snbstantially as described.

In testimony Whei'eof I have affixed my sig nature in presenoe of two wtnesses.

PERRIS W. GARDNER.
