HERBERT WILLIAM DREW, OF CHICAGO, ILLINOIS.

WINDOW-VENTILATOR.

Application filed. June 16, 1911.

To all whom it may concern Be it known that I, HERBERT W. DREW, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Window-Ventilators, of which the following is a specification.

The object of my invention is to provide a novel structure for ventilating the interior of a car which may be applied to the windows thereof. It may also be applied to the windows of residences and in other connections where a window ventilator is desired.

The principal object of my invention is to provide a device that will deflect the air currents in any desired direction as they flow into the car and to so arrange the device that it may be quickly adjusted to such positions and will be held firmly therein. I have also endeavored to produce a device that can be removed and folded with the utmost facility and which can be stored away when not in use. I have also provided a device in which the deflecting shutter may be detached and interference with the air currents entirely removed.

Other objects and advantages of my invention will become apparent in the following specification when taken in connection with the accompanying drawings, in which- Figure 1 is an elevation of a portion of the interior of a car showing my Ventilators attached to the windows. Fig. 2 is a perspective view of the ventilator with the cleflectors adjusted in opposite directions to throw the currents upwardly and downwardly. Fig. 3 is a perspective view showing the shutters adjusted to throw the currents in opposite horizontal directions. Fig. 4 is a perspective view showing one of the shutters closed and the other adjusted to a vertical position spaced from the frame. Fig. 5 is a horizontal sectional view of a portion of the ventilator at one end. Fig. 6 is a transverse section thereof taken substantially along the line 6, 6.

In Fig. 1 the ventilator is shown at 15, the window sash being elevated sufficiently to Specification of Letters Patent.

permit its disposal in the window frame beneath said sash. The frame may be grooved at its upper and lower edges at 15'" to permit the attachment of any suitable packing. In the drawings I have shown the ventilator made of two

portions

16 and 17 hinged to gether at 18. Inmany cases, however, a single section may be sulficient, while in others a greater number of sections may be hinged to each other.

The ventilator is provided with an opening 20 into which the shutter 19 is fitted. The shutter is preferably made of glass which is held in the frame 21. This frame is provided with trunnions 22 at opposite ends which project outwardly and are adapted to enter supports 23 which are pivotall7y attached to the ventilator frame 16 or 1 The trunnions 22 enter slots 24 in the said supports and may be firmly but yieldably held in either

end

26 or 27 of said slots by a flexible member 28 which is secured at its

ends

29, 29 to the said supports. The flexible member 28 is given a tension such that it will press the trunnion 22 against the

inner edge

27 or 26 of said slots. The friction thereby produced is relied upon to hold the shutter in any position into which it may be adjusted. A notch 26 receives the trunnion and assists in holding it in place.

The slots 24 have a right angular inward extension 25 to which permits the trunnions 22 to be moved inwardly when it is desired to close the shutter. -When the trunnions have been moved to the inner ends 25 of the slots, the supports 23 may befolded upon the shutter. This is permitted by the pivotal connection 30 of said supports with the frame of the ventilator.

The support 23 is so pivoted to the main frame that it bears upon the outer ends of the shutter at 19* in closing and forces said shutter firmly against the flanges 16 of said main frame. The buttons 22 attached to said trunnions permit a locking of the shutter in its closed position thereby making it weather and burglar proof. Each button may be pivotally attached to a trunnion by a screw or pin 22 and may have a width equal to that of the body of the trunnion thereby permitting it to pass through the slot 25.

The pivot 30 is made in the lug 31 which is preferably formed of the same sheet of metal of which the support 23 is constructed. There is one of these lugs 31 at each of the upper and lower extremities of the support. The pivots 30 of the shutter 23 are preferably screws which are threaded into strips 33 attached to the interior of the ventilator frame.

The supports 23 are limited in their outward movements by screws 32 which bear at their ends upon the supports when they are open. These screws are preferably threaded into the ventilator frame and their heads 32 may be conveniently reached with a screw-driver when it is desired to slack back these screws to permit a greater opening of the supports 23. Nhen the supports have been moved to the position shown in dotted lines at 35, the shutter 19 may be removed from the said supports. It will be sufficient to slack back one only of the screws 32 to permit the support to swing to the position shown by the dotted lines 35 to remove the shutter.

The inner edges of the support 23 are preferably curved or flanged, as shown at 34, and the slot 25 terminates before the inner edge 3%? is reached, thereby leaving a small connecting bar of metal 349 between the upper and lower portions of the support for purposes of strength.

lit will be seen from the perspective views 2, 3 and 4 that the shutters in my improved ventilator may be adjusted to a great variety of annular and spaced positions with rela.

tion to the frame of the ventilator. In Fig. 2 one of the shutters is adjusted to throw a current of air upwardly and the other to throw it downwardly. By closing one of the supporting frames 23 the shutter may be adjusted in a horizontal direction, as shown in Fig. 3. This will divert the currents in horizontal directions. As shown in Fig. 4:, the shutter is shown in a vertical position and air currents upwardly and downwardly will be produced.

Various other positions of the shutter may be effected which will deflect the currents in any desired direction.

I have also attached the screen 36 to the ventilator frame and cinders and other undesirable objects are therefore excluded.

lVhile I have described more or less pre cisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form and the proportion of parts and the substitution of equivalents as circumstances may suggest or render expedient without departing from the spirit of my invention.
