FWINDIOW-VENTILATOR.

To all whom it ma y concern:

Be it known that I, WALTER LTHonNn, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State ofjOhio, have invented certain new and useful Improvements in Window -Ventilators, of which the following is a specification.

, My invention relates to ventilators of the character of those applied to windows for deflecting thecurrents of ,air passing into the room so as to prevent direct contact thereof with the occupants of the room.

I My invention consists innovel v means t-ached and adjusted to various sizes of windows and for deflecting the currents of air tomore or less extent, and the invention will be re'adilynnderstood from the following description and claims, and from the drawing, in which latter:

Figure l is a perspective view of my improved device shown in connection with so much of a window-opening as is necessary to illustrate my invent-ion. Fig. 2 is a vertical cross-section of the same on the line z-2 of Fig. 1. Fig. 3 is an enlarged front elevation of a detail showing the connection between the deflector and .-.window-frame. Fig. 4 is a vertical cross-section ,of the same on the line yy of Fig. 3. Fig.5 is a horizontal section of the same on the line try-00 of Fig. 3. Fig. (5 is a detail in. section on the line 'w-- w of Fig. 2, showing the means of adjustment for thedeflector-plates. Fig. 7 is a section on the line "Iio of Fig. 2, showing one end of the deflector.

My improved device comprises a plurality of relatively longitudinally slidable deflector-plates, shown at 1 2, which are pro- .vided with right angular end-portions 3 4,

shown bent from said plates at opposite ends thereof for forming flanges which taper toward their bottoms as shown by the angle between the edges 5 6 of said end-portions. The slidable connection between said plates is preferably accomplished by means of lips 7 on one of said plates for forming channels 8 between said lips and the body of said plate on which the lip is located, the other of said plates bein slidable in said channels 8 for forming a te escoping construction for said deflector-plates.

leasably secured to the respective side- walls 11, 12, of the windoiwframe 13 and act as supports for the deflector-platesf The attaching-plates are provided with apertures 15 comprising holes 16 from which slots '17 extend upwardly, the holes being sufficiently large to receive'the heads 18 of screws 19 screwed into the sidewalls 11.12 of the window-opening, the heads of said screws being distanced from said side-walls sufficiently to receive the thickness of the attaching-plates between them and the side walls, these attaching-plates being arranged to be received over the screw-heads by passing the holes 16 about said heads and then lowering the attaching-plates so that the walls of the slots 17 will be received about the shanks of the screws and be held in place by the heads of the screws, with the lowering ends of the attachin -plates adj acent to the sill 20 of the win ow. 'lhe end-portions 3 t are pivot'ed to the attaching-plates as shown by the pins 21. i

25 is ascrew on each of the attachingplates which passes through the slot 26 in each of the end-portions 3 4, a nut- 27 being received about said screw for clamping the end-portions to the attaching-plates at any desired angle to which the deflector-plates I l 2 may be swung on the pivots .21.

My improved construction permits the attaching- Hates to be releasably placed in position close to the sidewalls of'the -windmv-opening, and close slipping connection to be maintained between the end-portions and attachingplates I preferably employ a plurality of attaching means between each attaching-plate and the side-wall adjacent thereto, and place the plurality of attaching means and the pivot on said attaching-plate out of line with one another for permitting the edge 5 of the end-portions to be brought closer to the window and thereby increasing the range of adjustment for angle of the deflector-plates. I prefer to provide each proved device is adapted for ata I p 965,831

' tachmentto window-frames of various widths, and the device can be readily attached and detached as may be desired.

In attaching m device, it is placed between the walls 0 .the window-opening and the deflector-plates 1 2 are pulled laterally for bringing the attaching-plates into range of the screws 19, when the holes 16 are received about the heads 18 ofitlie screws 19 and the attachin -plates are lowered for bringing the slots 1 to rear ofsaid heads, thus forming a ready connection between the window-frame and attaching-plates. The angle of the deflector-plates is regulated by convenient means and to desired extent so as to cause. the currents of air to be deflected 1n desired directions, the means for.

changing the angle being convenient so that every time a change in the elevation of the window "is made, a change may also be promptly made in the angle of'thedefiectorplates, if desired; In my improved device,

1 further, the window may be entirely closed,

oted, means for releasabl securing said attaching-plates to the wa ls of the window opening, and adjustable clamping means acting upon various points between said deflec tor-plates and attaching-plates arranged for selectively swinging said deflector-plates to desirable positions on their ivots and securing the same in said desirab e positions, substantially as described.-

2. A window ventilator comprising a plurality of deflectorlates slidable one upon the other and provided at opposite ends with 'ri ht-oangular end-portions integral therewith which taper toward their bottoms,"at

taching-plates arranged to be releasablysecured to the walls of the window-opemng, the said end-portions having pivotal con "cured at selective points lengt nection with said attaching-platesand adjustable securing means between saidendportions and attaching-plates actin at se-.

lective points therebetween for sellectively changing j the angle of said deflector-plates on said attaching-plates, substantially'as described. 3. A window ventilator com rising a plurality of deflector-plates slidalile one upon the other and. provided with substantially rightangular end-portions bent up therefrom at opposite ends of said respective de 65 flector-plates,- attaching-plates from which said deflector-plates are pivotally supported, said attaching-plates being provide with openings merging into reduced slots for forming slip connectionwith screws on the 7:0

window-frame; clamp-screws on said attaohin -'plates,-i-'-'said end-portions provided with s ots through which saidclamp-screws pass, said 'clai'np'screws arranged to be so slots for selectively changing the. angle of -'deflector-plates, substantially as described. '4 In 'combination,- a window ventilator comprising. a plurality of defiectorlates 0 'lidableone uponthe other and provi ed'at opposite ends with substantially rightan larlend-portions, attaching-plates provi ed with pivots from which said deflector- ,plates are pivotallysupported, each of said 5 attaching-plates being provided with a plurality of connecting means for attachin devices arranged to besecured to the wafis of said Window-openin said plurality of connecting means and t e ing-plate being out of line with one another, said end-portions being provided with "slots, and clamping means on said attachingplates passing through said slots and arranged tor being clamped at selective points lengthwise of said slots for selectively changing the angle of said deflector-plates, substantially as described.
