To all whom it may concern: I p

Be it known that'MERr T. ,B'UCKLEY, a

citizen of the United States .1 of f America,

residing at WVichita, in the county of Sedg- Wick and State of Kansas, has invented certain new and useful Improvements in Ventilators, of which the following a specification.

My invention relates to ventilators and more particularly to siphon ventilators.

The principal object of the invention is to v obtain a maximum-outside and inside air capacity and maximum siphoning action for view partly broken base pipe of the ventilator which communi cates at its lower end with the usual vent pipe (not shown). This tubular body portion is connected at the upper end or is integrally formed at said upper end with an outwardly flared tube 6. Extending around thetube 6 scalloped at its top edge, are cir-. cumferential rows'of vertically alined air inlets 7 formed by slotting the tube 6, at

intervals in a horizontal'plane and pressing inwardly that portion of the tube directly beneath the slots to form ducts. The extent of the flare of the tube 6, as well as the size and number of inlets 7, will be determined or regulated according to the size of the base 5. A downwardly and outwardly flared flange 8, is connected at its upper edge with the base tube 5, at the point of juncture between the latter and the upwardly and outwardly flared slotted tube 6. This flange serves to direct the outside currents of air upwardly to the interior of thevbase tube for an obvious purpose.v

Vertically disposed spaced fins 9, secured to the tube 6, support a downwardly and outwardly flared skirt member 10, which encloses the entire tube 6, and a portion of the base tube 5, and serves as a jacket for siphoning the outside air upwardly between ma skirt and the-tubes adraaa inwardly" through the' -air ducts'l' "Theffins 9,-als1o1p, I I separate the outside air delivering 'tliefsame" di fi'erent POOktS' through} the several thus formed.

The cone shaped top 12, of the ventilator is secured in place and supported by means of outer fins let, secured to the outside of the skirt 10, at the upper end thereof and to ring 13 which braces" the top of skirt-10. These outer fins 14, also serve to break up the upwardly flowing outside, air currents passing between the skirt andthe outer band 15,- connected to the fins 14 and; encircling the top 12, in spaced relation thereto. The

outer upper fins 14:, are preferably arranged in staggered relation to the inner lower fins 9. By this staggered'arrangement, air currents not directly in thespace between two lower fins are directly inthe space between I upper fins, thereby insuring a better flow.

' From the foregoing it is thought the operation of the invention will be clear, but the same may be briefly described as follows tively between the flange8, and the skirt 10 and through the slots 7, between the skirt onthe inside of the tubes '5 and 6 thereby accelerating the escape of the inside air. As

The outside air currents passing respecthe two currents of air, one from the inside of the building to be ventilated and the vother from the, atmosphere require more space than is provided by the base tube 5 the tube 6, which is in effect an extension of the base tube 5, is outwardly flared to provide the increased volume necessary to accommodate boththe inside and the outside air,thus preventing the checking of the flow of the inside air.

By arranging the air ducts in vertical alignment, they materially air each other, the combined number ina tier, siphoning the air upward until the other air currents grasp it and take it out.

Having thus described myinvention, what i l I claim as my invention is:

1. A ventilator comprising a base pipe having an upwardly and outwardly flaring slotted extension, an outwardly and down wardly flared. flange secured'to said base at its point of joinder with the said extension, spaced fins secured to said base and said extension, an outwardly and downwardly flared skirt secured to said fins and enclosing said extension, fins attached to the outside of said-skirt at its-V upper end; and'ia Ventila. tor top and top band supported by said last mentioned fins, the two sets of fins being in staggered relation one to the other,

2. A ventilator comprising a base pipe having an upwardly and outwardly flaring" extension, said extension proyidedrwithrcineumferential rows of 'vertieally' alignedslots,

an outwardly, and downwardly flared flange; secured tosaidbase; at. itspointof jjoinder-t withithe 'said extension, spaced fins secured; to said base andvsaidgextension an, outs wardly and downwardly flared skirt secured to said".fi11sandi enclosingv said "extension, fins attached to the outside of said sltirt at its upper end, and a Ventilator top and top bandtsupportedibytsaid last mentioned fins, the two sets of fins being in staggered relation one to the other.

In testimony whereof I afiix my signature in presence oftwo witnesses.
