COWL.'
SPIlCYIEICATIONv formingpart of Letters Patent No. 352,573, dated November 16; 1886. Application filed June 1, 1886. Serial No.'203,l05. (No model.)
T all whom it may concern:
Be it known that I, OTTO ROTTON, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York,
have invented certain new and useful Improvements in Cowls; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing, making a part of this specification, and to the letters and gures of reference marked thereon.
The present invention has relation to cer tain new and useful improvementsA in cowls for the tops of chimneys or Ventilating-shafts, and the Object thereof is to improve their construction, whereby the ascending column of smoke, gas, or foul air is unobstructed in its course and free to escape, thus providing a cowl effective in its purpose and certain in its action. These objects lattain by the construction substantially as shown in the drawing, and hereinafter described and claimed.
'In the accompanying drawing I have shown a perspective view of my invention` the hollow column or shaft being partly broken away to show the lower end of the supporting-rod and transverse braces. This column or shaft A may be of any suitable diameter and length desired, and the braces c are secured to the interior thereof, as shown, any number being used as found preferable, the rod or spindle b supported thereby in the usual manner.
The cowl B may be ofany ofthe'usual forms, and is provided at its lower end with a converging plate or deflector, C, having side anges, c, and a collar, d, which fits over the upper end of the hollow column or sliaft A and rotates thereon, the del'lector C carrying with it the cowl B. The defiector C has outwardly-curved vanes D upon and against which the current of air acts, causing a rotation of the cowl and deliectoi', the vanes bringing the latter to face the wind or current of air. Thus by the inclination of the converging plate constituting the deliector the horizontal currents of air are deflected upward, as shown by the arrows, and ejected through the cowl', thereby causing a current of corresponding velocity to ascend from the hollow column or shaft,
vacuum caused by the passage of air over, upward, and around the lateral space e, between` the lower end of the cowl and the end of the column or shaft.
from which it is drawn by the comparative y When no wind is blowing, there is no oby struction to ascending column of sewer-gas, which heretofore formed an obstruction 1ncowls of ordinary use, and the natural iiow of air over the column'or shaft has its full play without any obstruction, the peculiar form of 6o the deliector, as hereinbefore described, directing the wind up and around it, causing on its lee side an exhaust.
` A very important feature of my invention is locating the lower end of the .cowl B some distance above the'end of the column or shaft A, so as to form an air space or passage between them. allowing the air to act on the column or shaft with greater effect than weie the cowl set down over the end of the same, the 7o current of air passingdirectly over the open end of the shaft or column through the space e. A natu ral liow ofair is always secured over the upper end of the hollow shaft or column, the exhaust Vcaused by the detlector to windward collecting another flow of air to rush over and around the sides, no' obstructionin the shaft or column to the ascent of air` soot, or gas being presented, and consequently cannot clog by soot, snow, or rain freezing thereon. 8O
-When there is little or no air stirring it offers no impediment to ascending current,` and draws air with less wind than the cowls in ordinary use, and allows no downward current.
I ani aware ofthe construction disclosed by l the expired pulentofC. F. Thomas, No. 14,171, granted January 29, 18,56, and I do not claim,
broadly, any feature shown in said patented construction.
Having now fully described my invention,
IOT
