VENTILATOR.

Application filed July 20, 1927.

proper or to hold the shutter against the ven;

tilator for closing the same.

A further obj ectis the provision of a ventilator for windows in the nature of a sub stantially rectangular frame having a reticulated facing and having doors or shutters swingable toward or at desired angles therefrom, to permit of the desired amount of air currents passing through the window casing and to likewise prevent the entrance of moisture through the ventilator, the said ventilator being provided with adjustable slides movable through the ends thereof, to contact with and frictionally engage the sides of a window casing.

To the attainment of the foregoing and other objects which will present themselves as the nature of the invention is better understood, the improvement resides in the construction, combination and arrangement of parts, a satisfactory embodiment of which is disclosed by the accompanying drawings.

In the drawings:

Figure 1 is a perspective view of a ventilator in accordance with this invention.

Fi ure 2 is an approximately central longitu inal sectional view therethrough.

Figure 3 is an elevation showing the door or shutter closed against the ventilator.

Figure 4 is a transverse sectional view showmg the ventilator in applied position.

Figure 5 is a similar sectional view illustrating the door or shutter swung to partly open position.

Figure 6 is a perspective view illustrating a slight modification.

Referring now to the drawings in detail and to Figures 4 and 5 in particular, the numeral 1 designates a window casing, 2 the lower slidable sash thereof and 3 the sill of the casing. Arranged on the casing 1n contact with the sill 3 and between the beads provided for the sash 2 there is my improved ventilator. The ventilator comprises a substantially rectangular frame 4, open at its rear and having its front closed by a re ticulated facing 5. The facing 5 is of the Serial No. 207,232.

usual wire mesh. The upper and lower members of the frame are of metal and have flanged edges, andthe said upper and lower members are connected at their ends by blocks 6 which may be of metal or wood. On the outer faces of these blocks there are fixed metal plates 7 that have their ends formed with ears or barrels 8 for the reception of pintles 9 on the lower ends of a shutter 10. The

shutter is preferably of metal and is of a.

length corresponding to that of the frame be tween the ends 6 thereof and the upper or outer edge of the shutter 10 is bent upon itself to provide the same with a head 11.

Fixed on the top of the frame 4 there is an angle plate 12. The inner and upstanding flange 13 of this plate is designed to contact with the inner face of the lower rail of the window sash 2 as disclosed by Figures 4 and 5 of the drawings. The outer end of this plate has hingedly secured thereto, as at 14, a strap 15. The strap is preferably of metal and is provided throughout its length with transversely arranged bulged or corrugated portions 16 affording inner grooves for contacting engagement with the beaded edge 11 of the door or shutter 10 and whereby the said door or shutter may be swung at desired outward angles with respect to the frame. In addition to the corrugated portions 15 the strap is formed with an offset portion 17 to engage with the head of the door or shutter when the latter is swung against the frame. There is a frictional engagement between the barrels 8 and the pintles 9 of the shutter so that the free swinging of the shutter is thus prevented.

In Figure 6 I have illustrated a slight modification in which the frame is provided with spaced reticulated portions 18 and separate shutters 19 for closing such portions.

In both constructions there is arranged for slidable movement through the ends of the frame plates 20. Each of these plates has an offset or hooked end 21. The plates 20 are frictionally engaged by the inwardly directed portions 22 of the top and bottom elements of the frame so that the free sliding of the plates is thus prevented. The offset or hool ed portions 21 of the longitudinally ad iustable plates 20 are designed to be received in the grooves in the casing 1 that prov1de the guldeways for the sash 2, and if desired to contact with the parting beads between the casing and the sash.

The simplicity of the improvement and the advantages thereof, will, it is thought, be perfectly apparent to those skilled in the art to which such invention relates when the foregoing description has been carefully read in connection with the accompanying rawings, but obviously I do not wish to be restricted to the precise details herein set forth and, therefore, hold myself entitled to make such ceived in and frictionally engage with the barrels, said shutter having its upper edge rounded to form the same with a bead, an angle plate fixed on the top of the frame and designed to have its upstanding flange contact with the inner face of the bottom rail of the lower sash, a strap hingedly secured to the angle plate having an offset portion and having corrugations designed for engagement with the head of the shutter for holding the shutter against the frame or at angle positions with respect to said frame, plates slid able through the ends of the frameand guided between the flanges and the top and bottom of the frame and the blocks at the ends of the frame, said plates having offset ends to he received in the grooves for the sash m the W111- dow casing, and a reticulated facing for the frame.

In testimony whereof I afix m y signature.
