I U CHlMNEY-COWL.
Specification of Letters Patent.
Patented Dec. 25, 1906.
Application filed April 25, 1906. Serial No. 313.694.
To all whom may concern.-
Be it known that I, PETER E. LoRENzEN, a citizen of the United States, residing in Mariners Harbor, in the county of Richmond and State of New York, have invented certain new and useful Improvements in Chimney- Oowls, of which the following is a specification.
This invention relates to an improvement in ohimney-cowls for preventing the smoking of chimneys and producing an effective draft in the chimney,whatever be the direction of the wind.-
The invention. consists of a chimney-cowl which comprises the novel features of constructionand combinations of parts to be hereinafter described and claimed.
In the accompanying drawings, Figure 1 represents a side elevation of my improved chimney-cowl. Fig. 2 is a vertical transverse section through the same on line 2 2,
Fig. 1. Fig. 3 is a bottom view of Fig.1; and Fig. 4is a horizontal section on line 45 4.,Fig. 2.
Similar letters of reference indicate corresponding parts in the different figures of the drawings. Y
Referring to the drawings, a represents a rectangular casing which is provided at its bottom .with a pipe 0/, which is inserted into the chimney, so as to givea firm support for the cowl. The casing a is open at its top and provided with 'u ward casing-stays b, on
which is supporte a hood d, which prevents the ingress of rain into the casing and per-.
'mits the. outlet of smoke in every direction, according to the direction of the wind.
In the side walls are arranged horizontal openings 0, of semicircular shape, which extend with their straight ends nearly across the side walls of the casing. Into said semicircular or segmental openingso are inserted laterally-curved scoop-shaped and .u wardly and inwardly inclined deflecting-p ates e, which project to the outside of the casing to a less extent than to the inside of the same, said deflecting-plates being attached at 'the ends by rivets or otherwise to the side walls of the casing and soldered intermediatelyof their length to the inwardly-extending integral flanges e at the lower curved edges of the segmental openings 0. The plates 6 taper abut attheir side edges against the corners of the segmental openings. The cowl shown in Fig. 1 is'provided withltwo scoop-shaped deflecting-plateson each side; but it is obvious that a greater number may be arranged,
according to the size of the cowl.
the chimney and carry the smoke in upward direction and out on that side which is opposite to the ingoing side of the wind. As the deflecting-plates gather the wind they change the direction of the same according to the inclination of the scoop-shaped deflectingplates. The wind then strikes against the lower surface of the opposite deflectingplates, by which the same is again deflected 1n upward direction and leaves at the u ward end of the casing below the hood. hatever be the direction of the wind, the action of the same on the smoke will be the same that is to say, an upward motion is imparted to the same toward the upwardend of the cowl, while sufficient suction is exerted on. the chimney to impart a good draft in the same and prevent smoking.
Having thus described my invention, I claim as new and desire to secure by Letters Patent A chimney-cowl comprising a rectangular casing having semicircular openings in the side walls thereof, the curved edges of said openings being lowermost and provided with inwardly-disposed. integral flanges, and laterally-curved deflecting-plates supported intermediately of their length on said flanges and-abutting at their side edges against the corners of said openings, said plates being inclined upwardly and inwardly and tapered toward their upper inner ends.
In testimony that I claim the foregoing as my invention I have signedmy name in presence of two subscribing witnesses.
' PETER E. LORENZEN.
