The sliding friction between the slats of the respective shutters is preferably such that selfadjustment, as when the ventilator is suspended the-median plane of the ventilator. The upper outer end portions of the arcuate openings are offset at 13 for that purpose. The various slats may be stiff or resilient, as desired, and thevarious web openings are preferably generally arcuate, substantially as shown. The web openings in each bracket are cut so that their respective ends are in parallel lines, and also so that the slats fitted therein overlap slightly, in an up-andappended claim, which is to be interpreted as broadly as the state of the art will permit.
We claim: V
A rectangular window ventilator having air inlet and discharge faces and comprising shutters telescopically connected together for adjustment to fit windows of different widths, each down respect, to preclude the outside air from entering the room in a horizontal path, even when the median plane of the ventilator is somewhat inclined to the vertical. The outer end brackets l6 and 26 may be formed with holes I4, preferably in the upper ends of their webs 58 and B6, respectively, to receive nails, screws or the like 16 for fastening the ventilator to the stiles 18 of a window frame 82. r
The ventilator constructed in accordance with our invention is telescopic and hence capable of adjustment to fit windows of various widths. When disposed in the plane of the window sash 84 with the outer end brackets l6 and 26 disposed in the stile grooves 86, the ventilator may be held in place by the window sash, or the ventilator may rest in either stile groove at any desired angle independently of either window sash. When disposed on the window sill 90 within the Window casing, the ventilator may be secured to the casing vertically or at any desired inclination. The
bottoms of the brackets are preferably bias cut, as shown at 94, providing a fulcrum in the form of a series of alined bracket flange edges 96 adapted to firmly grip the surface on which the ventilator rests and to allow the ventilator readily to be tilted about such fulcrum to the desired inclination.
The echelon arrangement of the slats provides for the incoming air a plurality of rising paths or fines of gradually increasing slope and decreasing size, divertingthe air upward and hence away from immediate contact with occupants of the room, the air issuing from each flue exerting suction on the air at the outlets of the immediately adjacent flues, so that all of the air is accelerated into the room.
The slats may be made of steel or aluminum or other suitable metal, or of wood, plastic or shutter comprising two end brackets, one being disposed between the end brackets of the other shutter, the outermost end brackets being channels, the flanges of each channel extending away from the other channel, each of the innermost end brackets having a web and a flange, the webs of all of said brackets having successively overlapping series of arcuate openings arranged in echelon and respectively in register with the arcuate openings in the other webs, each shutter having transversely concave-convex slats extending through its openings, all of said slats being of gradually increasing slope upward toward said discharge face of the ventilator, an end of each slat of each shutter terminating within and secured to one of said channels, the other end of each of the top and bottom slats of each shutter terminating within and beingsecured to the innermost end bracket of the same shutter, the slats of each shutter slidably passing through the openings in the innermost end bracket of the other shutter, the tops of said brackets being normal to the axes of said brackets, the bottoms of all of said brackets being mitered so as to provide alined bottom edges defining a fulcrum to facilitate tilting of the ventilator to a vertical or inclined position in a window frame.
