2 Claims.
This invention relates to ventilators and more particularly to an improved window ventilator which can be adjusted to either draw fresh air into a room or exhaust stale air therefrom.
The principal objects of thisinvention are to provide an improved Window ventilator which can be mounted in a window opening and which is so constructed that it can be adjusted to fit into various sized window openings; to provide a window ventilator of the aforementioned type in which the fan and driving means therefor are supported by a panel-like member, and are enclosed by a grill which isadapted to be swung away from the panel member to permit access to fit in various sized windows, a pair of transversely opposed, like end panels [5 are telescopically received between the upper and lower flanges 9 of the central panel 1. The end panels [5 are adjustably connected to the central panel 1 by means of bolts l! which pass through elongated horizontal slots l9, adjacent the upper and lower edges of the end panels [5. Nuts 20 are carried on the bolts I! for securing the endpanels I5 to the central panel 1.
Therefore when the ventilator is inserted within a window opening, the end panels l5 can be moved inwardly or outwardly with respect to the central panel 1 so as to properly close and fit into the fan and driving means; to provide a window the window opening, between the window side ventilator of the aforementioned type in which frame members l3. The window sash H can then the fan and motor means therefor are rotatably be moved to abut the upper edge of the ventilator, supported by the panel member so that the fan as shown in Fig. 1, while the lower edge thereof may be selectively swung to either a position for rests upon the window sill 14. The outer ends of drawing fresh air into a room or to a position for the end panels l5 are bent outwardly 90 to proexhausting stale air from the room; to provide vide vertical flanges 23. The flanges 23 are proimproved means for so rotatably supporting a fan vided, adjacent the upper and lower ends thereof, and its motor means and for retaining the same with open L-shaped slots which are adapted in an adjusted position; to provide an improved for use in attaching the end panels to screws 24 ventilator of the aforementioned type which is 25 threaded into the vertical window frame members especially neat in appearance, rugged in conl3. The central panel 1 is provided with a censtruction, and relatively inexpensive to manutral circular openin 21 defined by an annular facture. outwardly projecting flange 3 I, for a reason which These and other objects of this invention will will hereinafter appear. become apparent from the following detailed de- A grill, generally indicated at 33, is hingedly scription taken in conjunction with the accomconnected to the inner face of the central panel panying drawings in which: I, over the panel opening 21.

Fig. 6 is a sectional view similar to Fig. 2 show- Welded the underside of the upper horizoning the fan and motor means therefor rotated i911 leg of the Central grill portion 3 s a sp 180 from the position illustrated in Fig. 2. like latch member 5|, the free end of which is Referring now to the drawings, it will be seen upwardly offset to provide a nose or latch portion that the ventilator includes a central panel I, 53. The central panel 1, adjacent the latch mem her, is provided with an aperture 55, so that when the grill 33 is in its normal vertical position the latch nose 53 will engage the outer face of they panel 1, above the aperture 55, and retain the grill in its closed. position. In order to release the latch to permit the upper edge of the grill to be swung away from the panel 1, about the tabs 45, as shown in dot and dash lines in Fig. 2, a button 51 is slidably mounted in the upper leg of the grill, and abuts the latch 5| disposed therebelow. By pushing downwardly on the button 51 the latch nose 53 will be moved out of engagement with the outer face of the central panel I, and into alignment with the aperture 55 so that the entire grill can then be swung inwardly about the tabs 45. The central panel I has four rubber grommets or tabs 58 secured to its inner face so as to abut each of the grill corner gussets 4| when the grill is closed. The grill, as can be seen in the drawings, is provided with a central escutcheon cup 59.
Supported on the inner face of the central panel 1, within the grill, when the latter is closed, and in axial alignment with the panel opening 21, is an electric motor enclosed in a housing 60. A drive shaft 6| projects outwardly through one end of the housing 60 and is operatively connected to a plurality of radially spaced fan blades 63, in. a conventional manner, so that the fan blades will be driven when the motor is operating. A transversfily extending horizontal strap 67 is provided for supporting the motor on the panel 1. The strap 61 is offset inwardly in the center thereof to fit the contour of the motor housing E0. and is secured to the housing 50 by means of studs and nuts H. The opposite ends of the strap 61 are bent outwardly at right angles so as to extend parallel to the drive shaft 6| and provide end por tions 13. A bolt 15 has its threaded end extende ing outwardly through each of the strap end por-. tions 13. 'A pair of channel section supporting brackets 11 are secured to the inner face of the panel 1, adjacent each end portion of the strap 61, and each of the bolts 75 is journaled inits ade jacent bracket. Wing nuts 19 are carried on the ends of the studs 75 to secure the latter to the brackets H. The motor 59 and the fan blades 63 are thus rotatably supported on the panel I, and by loosening the wing nuts 19 it is possible to roe tate the fan 180 from one position to another. That is the fan and motor can be rotated either to the position shown in Fig, 2, wherein stale air willbe blown out of the room,- or to the position shown in Fig. 6 wherein the fan will blow fresh air into the room. After the fan is in one or the other of these positions the wing nuts can be tightened to hold it in that position.
A conventional button type fan switch 8| is mounted on the inner face of the panel 1 adjacent the grill side wall 35, and is connected in series with the motor 60 and a conventional outlet plug 83, by means of electrical conduits 87. The conduit 81, connected to the motor 60, is secured to the supporting strap 61, adjacent the motor, by means of a clip 89, so that it is possible to rotate the motor 180 without breaking or tangling the same. Of course the fan and motor must be rotated back and forth in order to prevent winding o'f'the conduit around the strap 51.
It will thus be seen that the fan blades can be rotated so as to either blow air into the room or push air therefrom, and that in order to change the position of the fan, the grill latch 5i is depressed and the grill pivoted away from the panel 1. The wing nuts 19 are then loosened and the fan rotated to the desired position before again tightening the wing nuts. The grill can thenbe swung into its closed position so that the latch 5| holds it in place. The ventilator is-thus especially neat in appearance-,- easy to operate,
4 rugged in construction, relatively inexpensive to manufacture and can be easily inserted in any conventional window, and withdrawn therefrom when not in use.
