Another objcctis .tOgDIQVldQ ,a'window ventilator-which is adjustable to: lit various sizes of windowopenings.
er ob'ect is to provi'de'a plurality of ichmay be adjusted to control the e i ventilation opening or to close-the Another" bj'ect-is-to provide means to adjust said louveraand to secure same in their adjusted position, whether it be open or closed.
These and other objects and advantages of the invention will become more apparent as the description proceeds.
In the accompanying drawing forming a part of this application:
Fig. 1 is a fragmental perspective view showing the outer face of my ventilator device.
Fig. 2 is a top plan view of Fig. 1.
Fig. 3 is a vertical elevational view of the innor face of the device shown in Fig. 1.'
Fig. 4 is a fragmental perspective view showing some of the structural features of my invention.
Fig. 5 is a broken side elevational view of the device shown in Fig. 1.
Fig. 6 is a fragmental perspective view of one of the side extensions for the device.
Fig. 7 is an edge view of one of the dogs or catches for securing the ventilator in place.
Fig. 8 is a plan view of Fig. 7.
In the drawing, the reference numeral I indicates the body member of my device which, in this case, is a substantially rectangular piece of sheet metal having a relatively large opening 2 or folding the upper and lower edges of the latter back upon themselves, as at 1, and including the edges of the sheet 6 in the fold.
Each of the louvers 5 comprises an elongated strip of metal having its upper edge bent to l TErne'stA. Johnson, Dulu M plication ApriLZl, 1950, SerialNo. 157,385 I (0149 -9 3 I V vzarcuate-sliape, as at L-to pro ide for water shed and. streamlining of. appearance. .-The outer ends of the louvers:are/cutsoas'to extend outwardly of and to overlap the projection 4' of the .body member 'ofthe louver, as shown;v 'A lug 8ris perforated, as at 9, to .provide for-"pivotal mounting of the louvers in the opening 2; Aspin or-rivet l0 extendsthrough the perforations 9 and .a
similar perforation in the side projections! to secure'thelouvers in their desired positions. The
'ately below, as at: H ,fto' provide..f or, atight closure of the opening when the louver-spare in closed position.
As means for adjusting and securing the louvers to their desired positions, I have joined the louvers together so that they may be operated together. A vertical shaft [2 is pivotally secured to each of the louvers, preferably by means of a small lug I3 struck from the lower edge of each louver, as shown, with a pin l4 extending through the shaft and the lug. Thus, it may be seen, that the operation of one of the louvers will operate all of the louvers, or, the operation of the shaft will operate all of the louvers.
The opening 2 is divided, preferably centrally thereof, with a, member 15, which may be formed from the material of the body member if desired. Adjacent the upper end of the member I5 an elongated vertical slot 16 is provided, and an operating rod H extends through the slot l6 and is pivotally connected to the shaft I2 as by a pin [8 to provide means to adjust the position of the louvers. The ope-rating rod has a plurality of angular notches [9 in the stem portion thereof which may be engaged in the lower edge of the slot 16 to hold the rod and louvers in any desired adjusted position.
The rod I! is preferably of substantially J- shape, as shown, having a joining portion 20 which extends at right angles to the stem portion thereof, and an end portion 2! which extends substantially parallel with the stem portion. The outer end of the end portion 2| is pivotally secured to the shaft by the pin [8, as shown. This arrangement permits the locking of the louvers in closed position, as the stem portion may be pulled through the slot as far as possible and then pivoted inwardly against the member l5, as is apparent in the drawings. This clamps the louvers in closed position, as the portion 20 is of a length to extend from the shaft 12 to the member l5, as shown.
The opening 2 is covered with screen, sug- 3 gested at 22, to prevent insects and the like from entering the building when the louvers 5 are open.
To provide for adjustability of the device for use on various sizes of window openings, a slide 23 is provided on each side of the body member I, the slides being adjustable longitudinally on the body member. A slide stop 24 is provided on the body member I and a groove 25 is provided on the slide to permit adjusting of the slide to extend a predetermined distance beyond the body member when the stop will engage the outward flange 26 of the slide to prevent further outward move ment of slide.
My ventilator device is installed in a window opening after the window is raised, of course, the device being placed between the window guides, then the window is lowered to engage the top edge of the ventilator and hold it in place. A dog 21 is pivotally mounted on each of the extensions 23 on the outer edges thereof, as shown, they each having a toothed portion 28, as shown. By pivoting the dogs into engagement with the window guides on the frame of the window, the ventilator is held firmly in place and will not rattle or be blown from its position.
Having thus. described my invention, what I claim is:
A ventilator for a window opening comprising a. substantially rectangular body member having a relatively large ventilating opening therethrough, a screen over said opening, a plurality of louvers pivotally carried on said body mem-: her and being adapted to cover said opening when in closed position, a shaft pivotally connected to each of said louvers for operating all of same simultaneously, and an operating rod for controlling the pivotal position of said louvers, said rod having a stem portion, an end portion, and a joining portion extending between and at substantially right angles to said stem and end portions forming a substantially J-shape, said end portion being pivotally connected to said shaft, said screen having a slot therethrough in alinement with said shaft, said stem portion being carried through said slot to extend on the opposite side of said screen from said shaft, and said joining portion being of a length equal to the distance between said shaft and the opposite side of said screen when said louvers are in closed position whereby said louvers may be locked in closed position by pivoting said rod inwardly until said stem and end portions lie substantially parallel with said shaft.
