IMPROVEMENT IN VENTlLATORS.
Specification forming part of Letters Patent No. 174,304, dated February 29, 1876 application filed February 5, 1876.
To all whom it may concern:
. and figures of reference marked thereon.
Figure 1 ofthe drawings is a representa tion of a vertical central section of my ventilator, and Fig. 2 is a plan view of the same.
This invention has relation to ventilators for buildings; and thenature of myinveutiou consists in a novel construction of the cap or upper end of the ventilator-shaft, whereby. currents of air are prevented from diving down this shaft, and whereby water falling upon the dome thereof is carried off upon its outside, as will be understood from the above description.
In the annexed drawings, E designates the shaft of the ventilator, which may be of any suitable diameter; and F designates a segment of a sphere, the lower end of which is permanently secured to the shaft E, a short distance below the upper end thereof, as
shownin Fig. 1, and at l) openings are made for the escape of water on the outside of the shaft E.
A designates a dome, between which and the upper end of the shaft E is a horizontal space, a, for the escape of vitiated air from the building. The lower edge of the dome A is turned up, so as to form an annular gutter, which is perforated at O for allowing the escape of water,,which"falls into the channel around the upper end of the shaft E, and escapes at D. The upturned portion of the dome A will deflect or change the down currents of air. Surrounding the space a is a belt, H, which serves as a shield to prevent currents of external air from striking through the space a. This annular shield is of greater diameter than the diameter of the base of the dome A, for the purpbseof allowing a free as cape of air from the shaft E. The shield H is secured by short arms B, which unite'the portions A F to it.
What I claim as new, and desire .to secure by Letters Patent, is I In combination with the shaft E and segment E, the shield H and the dome'A, with' its perforated upturned base, substantially as described.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
