VENTILATOR Filed Jan. 24, 1928 Patented Dec. 2, 1930 STEPHEN E. CIBULAS, OF BRIDGEPOBT, CONNECTICUT VENTILATOR' Application filed. January 24, 1928. Serial No. 249,036.

This invention relates to ventilators, par ticularly of the type to be connected to a room to be ventilated by a passage leading through the roof, but it is by no means limited to such specific use as it may be employed for ventilating any desired enclosed space.

It has for an object to provide a simple and improved construction which will effectively ventilate the space desired without the use of moving elements.

It is also an object of the invention to provide a simple structure which will be snow and water proof and which will have a great discharge capacity.

It is a further object of the invention to provide a ventilator which will perform its function of sucking or drawing air or fumes from the space to be ventilated no matter from what angle or direction the wind may be blowing. It will also function to withdraw these fumes whether the wind blows or not.

With the foregoing and other objects in view, I have devised the construction illustrated in the accompanying drawing forming a part of this specification. In this drawa Fig. 1 is a partial side elevation and a partial vertical section of my improved ventilator, and with arrows showing its operation when the outside air or wind is moving downwardly with respect to the ventilator, and

Fig. 2 is a vertical section similar to the section of Fig. 1 but indicating its action when the wind is moving upwardly.

The ventilator structure shown comprises.

an upright conduit 5 which is open at its upper end and connected to the space to be ventilated, such as the room 6 of a building, and I have shown the ventilator as mounted on the roof 7. Over the open upper end of the conduit 5 is mounted a hood 8 which may be of different shapes, but is preferably substantially conical as shown, and it is of a size so that its lower edge extends some distance outwardly beyond the rim of the conduit 5. This hood is spaced a sufficient distance above the open end of the conduit to provide a clear passage for flow of air or other gases outwardly from the conduit.

Enclosing this space between the hood conduit are a plurality of

upright ring vanes

9, 10, 11, 12 and 13 which are spaced from the hood and conduit andfrom each'other to orovide upright air or wind passages outside of and across the pa ssage between the hood and conduit. "In the specification. and claims where it is desirable .to distinguish the ring vane 11 from the other vanes I have called this particular vane will be noted that edge of thehood 8 and is so as to form a passage be a ring baffle. It

the vane 9 encloses the lower spaced therefrom tween them, while the second vanelOv encloses the lower edge of the vane 9 and is spaced from the first vane to form an upright passage. 13 aresimilar to vane 18 encloses The vanes 12 and

ernumber of va'nes we can By uslng a greatsecure a greater outflow or capacity for discharge of air and gases without having any straight direct passage to the conduit for entrance of snow or rain.

About theupper portion of the conduit is a a sweat gutter 14: for collection of condensation andvwhich has openings 15 discharging to the roof. provideda damper 16 of Within the conduit may be any suitable type for controlling the ventilating effect or vary the capacity of the conduit.

drawings it will From reference to the seen that no matter in which direction the wind is blowing its pas spaces between the vanes,

sage through the and between; these vanes and the hood and conduit, will draw air and gases from the conduit. For example, as indicated by the arrows 17 in Fig. 1, downward flow of the air through the upright passages at the sides of the vanes will create a suction on the air and gases in the conduit 5 represented by the arrows 18 and will draw these gases out, and will thus ventilate the space with which the conduit is in communication. Referring to Fig. 2, if the wind represented by arrows 19 flows in the opposite direction or upwardly it will have the same effect on the gases in the conduit, and, of course, there will be the natural draft through the ventilator if there is no Wind blowing. This construction of ventilator is very simple and has a large capacity, with large exit passages which are effectively controlled against entrance of rain or snow. The vanes and hood may be supported on the conduit 5 in suitable spaced relation by means of supports or brackets 20. The various elements may be secured to these supports or brackets by bolts, rivets or spot welding, and the number of support-s may be as found desirable.

Having thus set forth the nature of my invention, what I claim is:

1. A ventilator comprising an upright conduit, a hood over the top of the conduit and spaced therefrom, a plurality of spaced upright ring vanes arranged with the inner one enclosing and extending above and below the upper end of the conduit and spaced therefrom and the next outer vane enclosing and extending above and below the upper edge of the next inner vane, a plurality of similar spaced upright ring vanes arranged with the inner one enclosing and extending above and below the lower edge of the hood and spaced therefrom and the next outer vane enclosing and extending above and below the lower edge of the next in er vane, the upper vanes being flared outwardly at their upper ends and the lower vanes being flared outwardly at their lower ends, and an upright outer ring baffle spaced from and enclosing the adjacent edges of the outer vanes.

2. A ventilator comprising an upright conduit, a hood over the top of the conduit and spaced therefrom, said hood being of suflicient diameter to extend outwardly beyond the periphery of the conduit, a plurality of spaced upright ring vanes arranged with the inner one enclosing and extending above and below the upper end of the conduit and spaced therefrom and the next outer vane enclosing and extending above and below the upper edge of the next inner vane, a plurality of similar spaced upright ring vanes arranged with the inner one enclosing and extending above and below the lower edge of the hood and spaced therefrom and the next outer vane enclosing and extending STEPHEN E.
