To aZZ whom if; may concern..-

Be it known that I, THEODORE T. DOLL, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Window-Ventilators, of which the following is a specification.

My invention relates to certain new and useful improvements in Window-ventilators; 'to and its object is to provide a ventilator which can readily be attached to windows of variou s spective of a window and sash provided with4 my improved ventilator. Fig.Y 2 is a section Nin line 2 2 of Fig. 1. Fig. 3 is a section in the line 3 3 of Fig. 1, and Fig. etfis a perspec tive of one end of the deflector removed from its place in the sash.

Referring to the drawings, A A are two telescoping parts ot' a delector. is provided with a triangular portion a. at right angles to it, the edges of the said triangular portion being provided with tianges a. The bottom edge of the portions A A is likewise provided 'with a flange a2 and in the same plane with andpreferably integral with the iianges a. Each of the portions A A',

the adjacent triangular portion a, and the' flanges is preferably forined'of one piece of sheet metal stamped into shape; but of course this method of construction is by no means essential. The deiiector is secured in place, as shown in Fig. 1, in-a window-frame by placing the tianges a outside the windowstops and elongating the telescoping detlector as far as possible, the flange a2 extending down outside the window sill. Two hooks are provided on the window-,frame which en- 5o gage with eyes or rings a3 on the deiector to hold the device in position. When this po- Each part v sition is reached, the window is brought down, running over the flanges a and wedgng said anges between itselfand the window-stops.

The deiiector, it will be seen from the above description and from the drawings, extends from the window-sill upward and inward into the room, providing a passage for air in an upward direction, so that air can enter the room without the possibility of rain coming 6o in also.

The regulation of the amount of draft entering is eected by acover` B, composed of two telescoping sections, said cover having ears B at its ends and at right angles to it. These ears are provided with slots b, each of said slots havingtwo notches b' b2. The cover is secured upon the delector by bolts b3, which extend through the dei'lector and also through the slots b. ment of the slots and notches is such that the cover can Ybe secured in a plurality of positions, as may be desired. The cover may be swung beside the delector, as shown in Fig.

1, so as to leave the entire space above the deflector open. It may be held in the position shown in Fig. 3, wherein thenut is in engagement with the notch b2, when a large opening ispresented for the entrance of air, and the cover turns the air directlyA into the-room in- 8o stead of upward. The cover may also be let down from the position-shown in Fig. 3 either to a position where-the nuts engage with the notches b', in which case a smaller opening is afforded for the entrance of air, or it ma be. let down entirely to close the opening. Other positions in which the' cover can be placed will also be apparent.

In Fig. 1 will beseen two washers a4, secured in placeA between the telescoping mem- 9o bers A A' of the deiector. These Washers are of felt, and their purpose is to prevent Vscratching of the two members when slid one It will be noted that the arrange- 7o lt is to be noted that the cover B is cut away at its ends t'o form notches b4 b4, so that when it is closed it will corne substantially into contact with the glass of the window, the notches being provided for the two sides of the Window-sash. The edge of the cover is wired, as shown in the drawings, to prevent the sash from being scratched and also to give the device a neat and finished appearance.

I realize that considerable variation can be made in the details of the device above described, and for that reason do not desire to limit myself to the specific construction shown and described.

I claim as new and desire to secure by Letters Patentl. The combination with a dellector, and means for securing the saine to a Windowfraine, said dellector when in position, extending diagonally inward from the windowsill, of a cover provided with ears overlapping the sides ot' said defiector, slots in said ears, bolts extending through the sides of said deflector and said slots, and means for engaging said bolts with different portions of said slots to secure the covei` in a plurality of varying positions.

2. The combination with a deflect-o1', and means for securing the same to a window frame, said defieotor when in position eX- tending diagonally upward and inward from the window-sill, of a cover provided with ears extending over the sides of Said deflector, notched slots in said ears, and bolts passing through the sides of said deflector and notched slots.

ln witness whereof I have signed the above application for Letters Patent, at Chicago, in the county of Cook and State of Illinois, this 24th day of February, A. D. 1903.

THEO DORE T. DOLL.
