VENTILATOR.
Patented July 13,1920.
Application filed September 2s, 1919. Serial No. 327,345.
I '0 all whom, c'tmay concern Be it known that I, OsoAn E. OLoUn, a citizen of the United States (rt-America, and resident of Wichita, in the county oi Sedgwick and State of Kansas, have invented certain new and useful Improvements in Ventilators, of which the following is a specification, reference being had to the accompanying sheet of drawings.
This invention relates to ventilators for the tops of air stacks, and belongs to the type known as siphon ventilators.
The invention and improvement consists in the provision of a number of verticalradial deflectors applied to the inner and outer faces of the hood, and to the novel. combinations and arrangements therewith of a conical deflector and other allied parts whereby an improved siphonage is produced and a free outflow of gases and air through the ventilator maintained.
Referring now to the accompanying drawings:
Figure 1 is a side elevation of a ventilator constructed according to the invention; Fig. 2 is a central vertical section of same; Fig. 3 is a top plan view of same; Fig. 4; is a detail view of material for one vertical-radial deflector; Fig. 5 shows a modified form of the hood in elevation.
The ventilator comprises for its principal parts, the body tube 1, (which forms an extension of the upper end of an air stack) the annular wind-guard 2, the cap 3, the conical deflector 4, and the frustoconical hood 5.
The hood 5 is supported from the tube 1, and the wind-guard 2 is supported from the hood 5. The cap and deflector 3-4 are supported in the ring 2 by means of brackets 6.
The hood 5 is held in concentric position by a series of pairs of sheet- metal fins 7 and 8 which are vertically and radially disposed. The inner fins, 7, have right-angled flanges 7' by which they are secured to the body tube 1 by rivets 9, and have similar flanges by which they are secured to the hood 5. The outer fins 8 are formed with flanges 8 fastened to the hood with rivets 10. The outer fin of each pair is in the same plane as the companion inner fin 7. These fins constitute air-deflectors, which have the function of directing horizontal winds upwardly and through the wind-guard 2. By reference to the drawings, it will be noted that the conical cap 3 is sufliciently large at its base to more than cover the eduction pipe 1 thereby preventing rain from entering said pipe, the conical deflector l integrally depending from the cap 3 has slightly smaller than the base of said cap, the apex of said deflector lhangs below the plane of the rim of the hood 5, said rim being flared as clearly seen in Fig. 2.
The wind-guard is secured to the upper ends of the outer fins 8 by small bolts 12 instead of being riveted, so that the parts carried by the wind-guard may readily be removed for cleaning or other purposes.
The upper ends of each pair of fins'7S are cut obliquely, so as to meet the upper rim of the body tube 1.
The lower edge 13 of each segment of the hood 5 is out upon an arched curve, as
shown, instead of straight across as they might be (see Fig. 5). This cutting-away is a feature of improvement for this reason :-it causes and permits a greater volume of moving air to enter the space between the hood and the body tube: this air willmainly be drawn upward, as indicated by darts on the drawing, and thus the total siphoning force acting upon the air within the stack will be augmented. It will be especially noted that the oblique cut given the upper portions of the fins 7 and 8 allow for a free circulation of air'above the top orifice ofthe eduction pipe 1 and that the conical deflector 4 dropping down below the flared rim of the hood 5, that is within the orifice of said hood, the said deflector cooperates with said flared rim and oblique upper portions of the fins to turn the gases and the assisting air currents as indicated by the arrows without the eddying and objectionable features now a condition that obtains in common practice.
In laying out a pair of the fins 7--8, a single piece is cut to the shape shown by Fig. 4, then the piece is divided along the central diagonal line.
In small sizes of ventilator, four verticalradial deflectors will be employed; in large sizes, a larger number. Such modifications may be employed as lie within the scope of the appended claim.
Having described my invention, what I claim and desire to secure by Letters Patent 1s tion pipe, upwardly tapering fins integral therewith and vertically radiating around a base but 60 A ventilator comprising a tubular eduethe outside thereof; afrusto-conieal hood surrounding said pipe and extending above theupper end thereof and having an upper outwardly flared rim portion said hood be ing supported by outer inclined edge portions of said fins; downwardly tapering fins wlthout said hood, rad1ating 1n the same a V VVitnesses eduetion pipe; a eoniealdefleetor, haying its base Within said cap and its apex depending therefromdownwardly to a point below the plane of the flared rim of said hood and Within said hood orifice; the upper edges of said inner and outer fins extending 0bliquely from the upper edge of said eduotion pipe to the base of said Windguard; all sub stantially in the niannerdisclosed and for the purposes as specified. 1
