VENTILATOB.

Specification of Letters Patent.

Patented July 4, 1916.

Application filed June 14, 1915.' Serial No. 38,984.

To all whom it may concern:

Be it known that I, GEORGE H. RUssELL, a citizen of the United States, residing at Florence, in the county of Lauderdale and State of Alabama, have invented a new and useful Ventilator, of which the following is a specification.

The present invention appertains to venti-i upwardly through the stack or ventilator pipe.

Another object of the invention, is to provide a ventilator head of such construction,

that the same will not be liable to leak, the ventilator head being provided with novel means for draining o-lf rain or moisture caught thereby.

As a further object, the invention aims to.

provide a ventilator head so constructed, that it will practically eliminate the possibility for down drafts through the ventilator stack or pipe.

It is also within the scope of the invention, to provide a ventilator head of the nature indicated, which will be comparatively simple, substantial and inexpensive in construction, and which will be practical and efiicient in use.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described.

tilator stack or tube 1 which is adapted to he slipped over the ventilator pipe 2 passed through the roof 3 of the building, for con ducting the foul gases upwardly therethrough. A conical base 4 is secured to the stack 1 adjacent its lower end to be disposed above the roof.

Surrounding the upper portion of the stack 1, is a cylindrical shell or jacket 5, which has its lower end spaced above the base 4, and which has its lower end provided with a frusto-conical or downwardly flared apron 6 disposed above the base 4. Radial partitions 7 are secured between the stack 1 and shell or casing 5, and'extend from the upper end of the stack 1 to the base 4, the lower ends of the partitions 7 being pro vided with angularly projecting extensions 8secured between the base 4 and apron 6. Thus, the partitions 7 and their extensions 8 not only serve to support the shell on the stack 1 and its base 4, but also divide the annular passage between the stack and shell,

to prevent a whirling motion of the air therein, and to cause the air to pass vertically within the said annular passage.

The upper end of the shell 5 projects above the upper end ofthe stack 1, and carries a bowl 9 having a lower opening receiving the upper end portion of the shell 5. Thus, the bowl 9 is secured upon the shell 5 so as to embrace the same below the upper end thereof, and whereby the upper end of the shell 5 provides an annular flange 10 upstanding from the bottom of the bowl 9 and surrounding the opening between the bowl 9 and shell 5. The bowl '9 is provided with apertures 11 adjacent the shell 5, and leading from the annular trough between the bowl 9 and flange 10, to the exterior of the shell 5. The apertures 11 enable any water or moisture caught within the bowl 9, to be drained off without the liability of the water flowing into or down the stack 1.

An annular trough or basin 12 is disposed within the bowl 9 above the shell 5, the trough 12 being of smaller diameter than the rim of the bowl and of larger diameter than the shell 5. The outer flange of the trough 12 has a dependingapron 13 from which any water overflowing from the trough will drip downwardly into the bowl 9, without dripping into the shell 5 or stack 1. The trough 12 is supported by means of upright inclined tubes 4 extending from the bottom of the trough 12 through the lower portion of the bowl 9 adjacent the apertures 11. The tubes 14 are arranged in an annular series.

The iimer flange of the trough 12 is pro-' vided with an outturned annular or overhanging lip 15 upon which a circular panel 16 of glass or equivalent material is seated. The panel 16 is preferably constructed of glass, in order that it will let light down through the stack, although the panel 16 may be constructed of metal or other suitable material, as desired. This circular panel or disk 16 is secured upon the lip 15 of the trough 12 by means of split ring 17 which embraces the lip 15 and periphery of the panel 16. The ring 17 is of U-shaped cross section so that its flanges overlap the lip 15 and panel 16 for holding them together, and the ends of the ring 17 formed by the split are provided with outstanding ears 18 through which a clamping bolt or element 19 is engaged for causing the ring 17 to embrace and clamp the panel 16 and lip 15. The panel 16 may be readily applied and removed when the ring 17 is removed, as will be apparent. The panel 16 provides with the trough 12, abaffle within the'bowl over the shell 5, and an annular outletfor the shell 5 is provided between the trough 12 and rim of the bowl 9. Any rain falling upon the panel 16 will run into the trough 12, to prevent the rain from passing downwardly into the shell 5 or stack 1. The water caught by the trough 12 will be drained out through the tubes 14:.

lVith the present ventilator, a wind blowing from any direction will be caught between the base 4 and apron6 and directed upwardly through the annular passage be tween'the shell 5 and stack 1 to create a suction at the upper end of the stack 1 for ejecting any foul gases upwardly from the stack 1, and to thus materially assist the natural upward draft within the stack 1, which may be sluggish. The partitions 7 and their extensions 8 prevent the air from whirling within the annular passage, and thus constrain the air to pass upwardly to create the suction.

The presentventilator will not be liable to leak, and will prevent rain or moisture falling through the pipe or stack 1, since any rain or moisture falling into the ventilator head, will be caught by the bowl 9 and trough 12. The water caught by the bowl 9 will be stopped from flowing into the shell 5, by the flange 10, and will drain outwardly through the apertures 11, while the water caught by the trough 12 will be drained outwardly through the tubes or'outlets 14.

The present device also prevents the possibility of down-drafts through the ventilator stack or pipe 1, since the trough 12 and panel 16 ordinarily prevent downdrafts, and the flange 10 upstanding from the bottom portion of the bowl 9, will also check any downward drafts between the bowl 9 and trough 12. However, should any air pass downwardly through the annular passage between the shell 5 and stack 1, it would not create any appreciable downdraft within the stack 1.

From the foregoing, the advantages and capabilities of the present invention will be obvious to those versed in the art, and it being noted that the structure'may be readily constructed from sheet metal of various qualities, in a convenient and inexpensive manner.

Having thus described the invention, what is claimed as new is:

1. A ventilator comprising a stack, a shell surrounding the same, a bowl carried by the upper end portion of the shell, the upper end of the shell projecting upwardly within the bowl to provide an annular flange, the bowl having drain apertures adjacent the said flange, a basin and ba'flie arranged within the bowl above the shell, and drain tubes extending from the said basin through the bowl.

2. A ventilator comprising a shell, a'bowl carried by the upper end portion thereof, an annular trough within the bowl above the shell, tubes connecting the bottom of the trough and bowl to allowfthe Water to drain off from the trough, anda panel carriedby the inner flange of the trough.

3. A ventilator comprising a shell, abowl carried by the upper-end thereof, an annular trough within the bowl above theshell, tubes connecting the bottom of the trough and bowl' to allow the water to drain off from the trough, the inner flange of the trough having an outturned lip, a panel resting upon said lip, a split ring of U-shaped cross section embracing said lip and panel to hold the panel upon said lip, and means connecting the ends of said ring for causing the ring to embrace said panel and lip.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
