ALEXANDER F. EAMSAY, OF MONTREAL, QUEBEC, CANADA.

VENTILA'IOR.

Application filed August 11, 1925. Serial No. 49,619.

This invention relates to new and useful improvements in ventilators, and the object of the invention is to provide a simple and economically manufactured ventilator which will be very efiicient in operation.

Another object is to provide a ventilator which will be easily opened and will not project beyond the frame by which it is attached when in the open or closed position.

A still further object is to provide a ventilator which will be easily attached to donble or storm windows in such a manner that they will be easily opened to ventilate a room without causing draught therein.

In the invention the ventilator is provided with a fixed portion and a sliding portion and means to form a grip for raising the sliding portion. The frame of the ventilator is made of H beam section and trans parent material, such as glass, celluloid, mica or the like, is mounted in both the fixed portion and the sliding portion of the frame.

In the drawings:

Figure 1 is a front elevation of a double window with my improved ventilator attached thereto.

Figure 2 is a sectional elevation of the device taken on the line 22 Figure 1.

Figure 3 is a perspective view of the yen tilator.

Figure 4 is a part sectional plan taken on the line 44 Figure 3.

Figure 5 is a part sectional plan taken on the line 55 Figure 3.

Referring more particularly to the drawings, 11 designates the vertical members of the ventilator frame formed of H beam section. The top horizontal member 12 is secured by any suitable means to the front flanges 13 of the members 11, while the lowermost member 14 is secured to the back flanges 15 of the vertical members. Positioned midway between the upper and lower members and secured to the front flanges 13 is the central fixed member 16, between which and the member 12 is mounted a sheet 17 of glass or such like transparent material. Surrounding the sheet of glass 18 is the frame 19, which is built of H beam section, the vertically disposed members 20 of which are slidably mounted on the flanges 15 of the members 11. All sections used in the construction of the ventilator are of the same section, namely H beam, so that the lowermost edge and side members of the sliding frame will fit snugly over the flanges of the side and lowermost members of the fixed frame and form a weatherproof joint so that no rain, snow or the like will pass through the ventilator when it is in the closed position. A chain 21, rope or such like flexible cord may be attached to the upper edge of the sliding frame to form a convenient device for opening the ventilator. In the drawing I have shown the vein tilators used on double or storm windows as an illustration of the utility of the device, but it will be readily understood that the manner of attaching the device may be modified without departing from the spirit of the invention. In Figures 1 and 2, 22 designates the lintel, 23 the sill and 24 the vertical members of the window. The members 24 may be provided with double grooves 25 within which are mounted the sliding window frames 26 and 27, each of which may be divided into two portions with transparentmat-erial mounted in each portion. Also mounted between the sill 23, lintel' 22 and vertical members 24, but spaced from the frames 26 and 27 is a window 30 of the usual construction provided with four panes of glass. One of the ventilators may be mounted in the uppermost part of the storm window 30 by removing one of the panes of glass, and another ventilator may be mounted in one of the lowermost corners of the frame 27 in a similar manner. My preferred manner of mounting the ventilators is shown in Figure 1, that is with one ventilator at one side of the window while the other ventilator is mounted on the other side of the window so that during severe weather the ventilators may be opened to allow the room to be ventilated without causing a draught therein. Suitable pulleys 28 may be mounted on the window framings for the operating cords 21.

From the foregoing description it will be readily seen that the ventilator is very easily and economically constructed and the frame being built of H beam sections allows the sliding members to fit snugly over the flanges of the fixed portion of the frame when the ventilator is closed, thereby forming: a perfectly sealed ventilator through which snow, rain or the like will not pass while it is in use. It is very simply operated and being of the sliding type no part will iii) project beyond the face of the Window or wall to Which it is attached. As shown, it provides an efficient ventilator for use With double or storm Windows and provides a means for ventilating a room during very cold Weather Without allowing too much cold air to enter the room.

Having thus described my invention, What I claim is 1. A ventilator comprising a frame having its marginal members formed with spaced inwardly projecting flanges, a transparent member applied to one side of the frame and extending over substantially the upper half of the frame, a second frame member having pairs of spaced side and bottom flanges, the inner flange of each pair being mounted to fit between corresponding flanges of the first mentioned frame, and a transparent member closing the center of said second frame, the latter being slidable from a closed position in the lower part of the first frame to an open position opposite the transparent member covering frame.

2. A ventilator comprising a pair of frames having the marginal members thereof substantially H-shaped in cross section, one of said frames being made longer than the other and the smaller frame having the inner side and bottom flanges thereof disposed between the inner and outer side and bottom flanges of the larger frame, a transparent member closing the center of the smaller frame and a second transparent member fastened to one side of the larger frame to cover substantially one half of said frame, said smaller frame being movable on and longitudinally of the larger frame to and from a position closing that part of the larger frame not covered by the transparent member secured to said larger frame.

In witness whereof, I have hereunto set my hand.

ALEXANDER- F. RAMSAY.
