Y Y VVENTILA'IOR FOR 'VVINIDOW'4 SASI-IES.

Application mea March s, 192s. serial No. 258,827.

It is the object of this invention tov provide a novel and improved ventilator, which is particularly adapted for use on storm or window sashes, and is of cheap and of simple construction and may be readily installed.

To this end, the invention consists in the, novel parts and novel combinations of partsv defined in the claims and described in the Y following specification made in connection Y' is. substantially rectangular in shape, has

with the accompanying drawings, wherein like reference characters referto Vthe saine or similar parts throughout the various views, and, in which7 Fig. lois a view in side elevation of a window sash looking outwardly toward the sash and illustrating. an embodiment of the present invention applied to the sash; v

Fig.` 2 is a horizontal section taken on the line 2*-2 of Fig/1, as is indicated by the arrowsg' v Fig. 3 is a verticalsection taken on the lineY 3 8 cf Fig. 2, as is indicated by the. arrows7 `certain of the parts being illus-v 6 having glass panes .7 therein is illustrated and thelower end of the windowsash is adapted to abut the sill -8 of a window frame. In accordance with the present invention, a plurality7 ofdraft openings 9 are provided through the base .of the. window sash and these openings project downwardly slightly from.` the innerside of the window sash to provide a ready'drainage for water.:

A cam sleeve opening 10 isf-also bored lin the .base of the window sash froml the inner side thereof outwardly to project almost through the sash. In accordance with the present invention', screening 11 is placed over `the openings 9 atl the inner `side of the window sash and an abutment plate 12 is secured tothe sash as byy nails rearwardly of the screening 11. The abutment plate 12 openingstherethrough in alinenient with the openings 9 and 10j andis'providedat its edges with a rearwardly projecting roll'12a forming, in effect, a rectangular frame5 the outer edges ofthe roll abutting the rear side of the window' frame. Secured to the central portion of the forward sideofv abut-Y ment plate 127 and projecting into the opening 10, is a cam 13. This cam has a fiat rear portion abutting the plate 12 and is provided with two arms. forming a sleeve- Y like structure which projects into the opening 10. The said arms have forward edges forming cam surfaces and these edges are generally curved diagonally outwardly from Y the Vplate 12, andare provided with a plurality ofsubstantially straight portions 13a forming steps inthe cam surfaces and disposedinfa plane generally parallel to the plane of the abutment plate 12. A stem 14 projects centrally through the abutment plate 12 'and cam 13, and is provided-adjacent its forward end with a squaredV portion having a pin v-15 mounted thereon as by means ofa nut lvscrewed on to .the forward endV of ,the stem. ,A .closure plate V17 is mountedon the steml 14 at the rear side of the abutment plate'12, and the said yclosureV plate is formed in the shape of a casing open at its forward slide, the edges of the casing being adapted to strike the abutment plate .'12 adjacent the central side of the roll 12ak therein. the 'stemy 14 and reacts between theabut- A coiled'spring 18veXtends around ment plate `12 and the forward side of the closure plate. Rearwardly from the closure plate,v a handle 19 is formed or secured to the stem 14.' YIn the drawings, the handle 19 is illustrated as being in the shape of a wing nut. Adjacent its two ends, the' abut# nient plate l2 has small U-shaped holders 20 stamped rearwardly therefrom andL a bar spring*21,secured to the forward 'Iside of- 'closure plated?, has outery ends fitting through the U-shaped holders for. slidingmovement therethrough. In Fig".4 5,A a clo-` sure plate 22 is illustrated, which is provided with `a forward recessed portion 22'#l on its rear side within `which the handle l19 on 'stem 14 may lit, so that the handle will not f project for any-substantial AVVdistance j rearwardly .fromK-the closure plate.

The two arms of spring 21 will placeV closure plate 17 underr tension to move away from theV abutment plate.A This movement l i will be limited by engagement of thepin 15 agon'ally vcurved.portions of to per1nit'thc springs 21 and 1S to torce the on the cam surfaces of the cam 13. 7When the key Vformed* by the` handle 19,. stem 14 and pin -is turned to its extreme Clockwise position, as viewed in the drawings, the handle 1S) bearing against the rear sideof the closure plate, will torce rthe same against" the tension of spring 2l` and spring 18so.
