VENTILATOR.

Applicationfi ledJune 30, 1922. Serial no. 571,905.

To all whom it may concern: I e

Be it known that I, LnsLIE Ci MoCAn'rNnr, aci'tizenof the United States, residing at Lincoln, in the county of- Lancaster and State of Nebraska, haveinvented'certain new and useful Improvements in Ventilators, of which the following is a specification.

This invention. relates to a ventilator. and has as one of its principal objects to provide a device of this character particularly adapted for use in conjunction with barns, hog houses, chicken houses, or other buildings.

A further object of the invention isto provide a device which will be StOlIIlaPlOOIE and will be so constructed that birds may be prevented from nesting within the ventilator hood.

And the invention has as a still further object to provide a device wherein the draft through the ventilator may be readily controlled.

Other and incidental objects will appear hereinafter.

In the drawing:

Figure 1 is a fragmentary plan view showing my improved device in conjunction with a portion of a roof,

Figure 2 is a longitudinal sectional view on the line 22 of Figure 1, looking in the direction of the arrows, and

Figure 3 is a transverse sectional view on the line 3-3 of Figure 1, looking in the direction of the arrows.

My invention is shown in one of its forms associated with a skylight. I employ an oblong frame which is preferably formed of suitable resilient sheet metal and comprises spaced parallel side bars 10 joined at corresponding ends thereof by an integral end bar 11 from which extends a center bar 12 lying medially between the side bars. Connecting the side bars at their opposite ends is a substantially semi-cylindrical ventilating hood 13 having side flanges 1a soldered or other wise secured to said bars. As best shown in Figure 2 of the drawing, the adjacent end of the center bar 12 is likewise soldered to the contiguous side flange of said hood, so that a rigid frame structure is thus provided. As will now be appreciated, spaced window openings are defined at opposite sides of the center bar 12 and closing said openings are panes 15 which are preferably formed of wire reinforced glass. As particularly brought out in Figure 2, the inner side margins of the side bars 10 and end bar 11, as

well as the opposite longitudinal margins of the centerbar 12, are bent up to form channel members lfiwhile similar channel memhers li'. areforined from the adjacent side flange of the hood 13, these channel members receiving the, margins of the panes and serving to tirmlyconnect said panes with the frame as well as also providing tight joints between-the frameand said panes. It will, of course; be understood that in any instance where it is. desired to construct the device of less width, the frame may. be made to accommodate a-single paneonly, the hood 13 bein of course, correspondingly shortened.

Mount-ed" at the ends of the hood 13 are substantially semi-cylindrical doors 18 which freely fit within the hood and swingingly supporting said doors are hinge rods 19 journaled through the sides of the hood. The doors are also preferably formed of suitable resilient sheet metal and may be rolled about said hinge rod for connecting the doors therewith, the hinge rods extending trans versely of the hood substantially at the plane of the side flanges 14. Formed on the hood at its ends are, as best shown in Figure 3, stop flanges 20 for limiting the doors in their movement to closed position and pivotally connected to the doors at the inner sides thereof are toggle members 21. Pivotally connecting these members at their inner ends is a coupling 22 and extending from said coupling is an operating rod 23. Thus, by pulling downwardly upon this rod, the

doors 18 may, as will be readily understood,.

be simultaneously opened while by shifting the rod upwardly, the doors may be closed. In this connection, it is to be observed that when the doors are closed, the coupling 22 is shifted to a position above the pivotal center of the toggle members 21, the doors 18 flexing to permit the upward movement of the coupling. Accordingly, the doors will be held closed by the weight of the ope ating rod 23.

In Figures 1 and 2 of the drawing, I have shown the device in conjunction with an ordinary shingle roof comprising a sheathing 24: to which are nailed the shingles 25. An appropriate opening is made in the sheathing, when the frame of the device is positioned against the sheathing to register with said opening so that the shingles may be arranged to overlie the frame for securely connecting the device with the roof as well as for excluding the elements. Thus, the device may .be readily applied and when so applied, the operating rod 23 will hang downwardly in convenient reach so that the doors 18 may be' opened and closed has desired for regulating the draft through the ventilator.

Having'thus described the invention, what is claimed as new is: T

1. In a device of the character described, a frame, a hood carried thereb open at its ends and provided with stop anges, doors movable to closed position abutting said flanges, toggle members pivotally connected to the doors, a coupling pivotallyiconnecting said toggle members, and an operating rod extending from said coupling whereby the rod may be shifted for manipulating the doors, the coupling being movable from a position below to a position aboveitlie pivotal center of said members wherebv'lthe rod will operate to hold the doors close 2. A device of the character described including ahood, doors swinginglylconnected therewith, toggle members pivotally connected to said doors, and means pivotally connecting said toggle members and movablefrom a position at one side to a position at the other side of the pivotal center of said members whereby the toggle members will hold the doors closed.-

3. A device of the character described including ahood, doors swingingly connected at their lower marginswith the hood and movable upwardly and outwardly away from each other to closed position, toggle members pivotally connected to the doors at the inner sides thereof, a coupling pivotally connecting said members,and an operating rod attached to said coupling and operable to shift the coupling from a position below to a position above the pivotal centers of said toggle members whereby the toggle members will hold the doors closed.

' In testimony whereof I affix my signature.
