UNITED STATES PATENT OFFICE.

JOHN OBRIEN, OF NEW WATERFORD, CAPE BRETON, NOVA SCO'IIA, CANADA- VENTILATOR.

Application filed February 18, 1924. Serial No. 693,695

To all whom'it may concern:

Be it known that I, JOHN OBRIEN, a

" subject of the King of Great Britain, residing at New I'Vaterford, Cape Breton, in the Province of Nova Scotia and Dominion of Canada, have invented new and useful Improvements in Ventilators, of which the following is a specification.

This invention relates to a ventilator for a window or the like, the general object of the invention being to provide means adapted to be placed under the sash of a window with the sash in partly raised position so as to permit air to enter a room while keeping out rain and snow.

Another object of the invention is to permit the device to be adjusted to suit different sizes of windows.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully. described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a View showing the invention in use.

Figure 2 is an enlarged view of the device itself.

Figure 3 is a section on line 3+3 of Figure 2.

Figures 4 and 5 are detail views.

In these views, 1 indicates the frame of the window, 2 the lower sash thereof and A indicates the ventilating device which is placed under the sash and rests upon the sill of the frame. This device consists of the two upright pieces 3, the ends of which are shaped, as shown at 4:, to engage the bottom of the sash and the sill. Each piece and are spaced apart to permit air to enter 7 between them. Each shutter is composed-of a ma or portion and a minor portion 7 which overlaps one end of the major portion and these two portions are slidably connected together by thev bent strips 8, which form guideways for receiving the edges of the portions. Thus the length of the device can be adjusted to suit different sizes of windows. Clips 9 connect the shutters with the uprights and I prefer to make the shutters of wedge-shape in cross section, as shown at 10. i

From the foregoing it will be seen that I have provided a simple device for permitting a room to be ventilated while keeping out the elements. The device can be adjusted to suit different sizes of windows.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent. I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is A ventilating device comprising a pair of upright pieces having their ends formed to fit the bottom of a sash and a sill of a window, the inner faces of the uprights having inclined grooves therein, shutters having their ends engaging the grooves, each shutter being composed of two wedge-shaped parts withtheir inner ends overlapping each other and bent strips on one part of each shutter forming guideways for the other part and clips for fastening the outer ends of the shutters to the uprights.

In testimony whereof I aflix my signature.

JOHN OBRIEU.
