VENTILATOR Filed Maron 8, 1929 Sidney Ll arr ATTORNEY Patented Nov. 5, 1929 UNITED STATES Application led March 8, `1929. SerialvNo. 3453314..

This invent-ion relates to ventilators for windows and particularly to that type of ventilators wherein the sheet of glass or of other suitable material is disposed, as an air deflector, in angular relation to a window and mounted on the window sill between window frame sides.

The object of the invention is to provide a readily adjustable device of the class indicated lo and especially useful in metal window frame 2g arrows.

construction.

Referring to the accompanying drawings forming a part hereof and illustrating the invention:

Fig. 1 is a front elevation with the inter mediate part of the ventilator and window broken away for economy of space;

Fig. 2 is a cross-sectional view taken on line 2-2 of Fig. 1, looking in the direction of the In this view the wind shield is shown in full lines close to the window and the broken liliesA indicate it in the fully opened position;

Fig. 3 is a sectional plan view taken on line 8-3 of Fig. 2, looking in the direction of the arrows; I

Fig. 4 is a detail sectional view on a larger scale, taken on the line 4-4 of Fig. 2. In this view only the frame is illustrated and the 3g intermediate part thereof is broken away;

and

Fig. 5 is a detail sectional view on a larger scale of the lower part of the ventilator.

Referring to the drawings, the reference numeral 6 indicates a sliding sash and window pane. The window frame comprises the sill portion 7 and frame sides 8.

Secured by screws 9 to the side portions of the window frame are V-shaped air and wind deflector plates 10 having flanges 11 on their inward or forward edges remote from the window. The upper edges 12 of these vshaped plates are curved and flanges 11 extend upwardly and inwardly.

Channel members 18 are pivoted at 14 to the V-shaped plates 10. These channel members fit snugly against the plates 10 and carry the deflector 15. One of each of the legs' of the channel members is bent at right angles, as

indicated? at16, and acts asa bottom support for the ventilator 125. A strip of'rubber 17 or Vsoas to prevent any. draught or air entering 'the-room, except that which is deflected lward yby the deflector plate.

The upper .parts of the members 1'3' extend above the frames 19 and have secured thereto by screws 18, on other suitablel means, strong flat spring` 19. Y, The freefends'QO of these spnings, as-.pamticularly shown in Fig. l4, bear against the outer sides of the plates 10. The curved edge 12 of the plates 10 are in an arc, the center of which would be struck from the pivot pins 14. The flanges 11 prevent the channel members 13 from being moved off the plates 10.

It will be apparent from the foregoing description and an inspection of the drawingsA that when the device is assembled one may easily grasp the deflector, or use the two upwardly-extending ends of the channelmembers 13 for handles, and move the deflector 15 from theV full open position indicated `in broken lines in Fig. 2 to a substantially vertical position, thus controlling the amount of fesh air to be admitted and the direction in which it will be deflected. The springs 19 form a simple and efficient means for holding the ventilator in its desired position.

The pivotal connection of the channel bar members which form a frame for the defiector 15 is between the deflector-holding frame and the side plates, preferably of metal, which, are secured to the window frame sides. The

preferably compressible strip 17 serves to eX- clude a draught between the window sill and the under edge of the deflector.

What l claim is:

As a newarticle of manufacture, an airdeflecting, window ventilator including a rockable, air-deflecting plate; a frame therefor comprising channeled members in which the plate is loosely mounted and slidable into and out of the frame; and rigid end plates to each of which the plate-holding frame is pivoted adjacent the under end of an end plate; means for holding said frame in adjustable position, the end plates being adapted for con-4- lme Yao

nection with the window frame sides; and a strip of compressible material along the un der edge of the frame structure adapted to engage a window sill and be compressed thereagainst when in use; the upper edges of the rigid end plates being severally arced from its upper, outer corner portion, inwardly, from its pivoted connection with the plate holding frame as a center, the channeled members of the plate holding frame including side members which project above the upper edges of the end frames; the cuter surfaces of the projecting channeled members being flat and the inward surfaces of the end frames being flat and the flat outer surfaces of the projecting channeled members each being in sliding Contact with a flat inward surface of an end frame; the end of a channeled member projecting above the upper edge of an end frame having secured to it a downwardly extending leaf spring7 the under free end of which is in engagement slidingly with the outward surface of an end frame. l j

Signed at Brooklyn, in the County ofKings and State of New York, this 5th day of February, 1929.
