SPECIFICATION 'forming part of Letters Patent No. 316,781, dated April-28, 1885.
Application filed July 31, 1884. (No model.)
To @ZZ whom it may concern:
Be it known that I, WILLIAM G. HENIs, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Chimney Oowls and Ventilators, which improvement is fully set forth in the following specification and accompanying drawings, in which Figure l is a front view of a chimney co-wl and ventilator embodying my invention. Fig. 2 is a longitudinal vertical section thereof in line x x, Fig. l. Fig. 3 is a horizontal section thereof in line y y, Fig. I. Fig. 4 is an end view of the cap thereof. Fig. 5 is a vcrtical section of a detached portion.
Similar letters of reference indicate corresponding parts in the several iigurcs.
My invention consists of a chimney cowl and ventilator constructed in such a manner that it produces an increased draft, rotates ,with great freedom, and is simple and inexpensive, all as will be hereinafter fully set forth.
Referring to the drawings, A represents the rotating cap,and B the stationary tube which supports the same, said tube being adapted to be inclosed or otherwise secured to a chimney, flue, or other place where the cowl' or ventilator is desired. To the top of the cap, on the under side thereof, is secured a depending spindle, G, whose lower end is rested on a step, l), which rises from a cross-bar, E, on the tube B.
Frepresents aring or annulus which is connected with thetop of tube B,and formed with lugs F', to which the ends of the cross-bar E are bolted, thus firmly securing said bar in position. Formed `with the annulus is a depending flange, G, which embraces the inner face of the tube B, and rising from said annulus is a saddle, II, the crown of which has an opening, a, constituting a boss, through which the spindle C is passed. In the spindle below the boss is inserted a pin or key, C', whereby upward displacement of the cap A is prevented.
J represents a brace which is formed with or secured to the top of the spindle C,-and riveted to or otherwise connected with the inner face of the top of the cap, thus strengthening said part of the cap,and preventing the spindle from being thrust through the same.
The cap and tube are preferably formed of sheet metal and the other parts described of cast metal, the annulus, lugs, flange, and saddle being in one piece. It will be seen that the annulus, with its iange and the saddle, forms a strong structure for supporting the cap, and as the spindle is rested below on the step D and encircled above by the boss or opening of the saddle, the cap is thereby nicely sustained, guided true, and caused to rotate with ease and uniformity. The cap A is formed of a tube somewhat cone-shaped, arranged horizontally or at a right angle to a vertical axis, and :open at the end from the wind. In the bottoni of the cap is an opening around which is a collar, A', which freely circuniscribes the tube B, the latter projecting into the cap through said opening. The end of the cap to the wind is closed by a conical deflector, K, which projects outwardly, and in the rim or plate b of said end are openings c.
The tube of which the cap is formed is broadened at bottom and narrowed at top, as seen in Fig. 1, the object whereof is as follows: When the wind strikes the deiector K, it is thereby forcibly directed into and through the openings c, and similarly driven through the narrow top of the cap, whereby an increased draft is created in the chimney-due, Src. rihe products of combustion, heated air, vapor, Ste., rising in the chimney are caught by the forcibly-impelled air, and as they are not checked or retarded, but permitted to expand in thewide base of the cap, it is evident that they are quickly expelled, and thus the cowl or ventilator operates with certainty and rapidity. It will also be seen that the device is formed of few parts, and is thereby simple and inexpensive. Owing to the weight superimposed on the cross-bar E, the same is formed with a rib, E', for strengthening purposes.
I am aware that cowls and ventilators have been constructed for the purpose of producing a vacuum in the rear end of the hood, so as to draw out the impure air and smoke, and such I do not claim, broadly.
Having thus described my invention, what IOO I claim as new, and desire to seeurevby Letters top, and provided with a conical defieotor hav- 1o Patent, ising openings in its rim,and a depending ange 1.
