HENRY O. REESE, OF BALTIMORE, MARYLAND.
WINDOW-VENTILATOR.
SPECIFICATION forming part of Letters Patent NO. 794,251, dated July 11, 1905.
Application filed March 23,1904. Serial No. 199,558.
To a whom it may concern.-
Be it known that I, HENRY O. REESE, a citizen of the United States, residing at Baltimore, State of Maryland, have invented certain new and useful Improvements in VVindow-Ventilators, of which the followingisa specification.
My invention relates to an improvement in window-ventilators, the object being to provide a light, simple, inexpensive, and effectual ventilator, which is adjustable and easily applicable to and removable from different-sized windows; and it consists in a sheet metal body portion extensible so that it may be adjusted t0 the width of the window, having an opening in the outer side for the entrance of outside air and provided with a door on its inner side, the latter being hinged at its lower edge, whereby to deflect the inflowing aircurrents upward.
It further consists in certain novel features of construction and combinations of parts, which will be hereinafter described,and pointed out in the claims.
In the accompanying drawings, Figure 1 is a view in perspective of a window, showing my improved ventilator in position therein and partly opened. Fig. 2 is a horizontal section of my improved ventilator. Fig. 3 is a transverse section, and Fig. 4 is an enlarged detail in section.
A represents a sheet-metal box of a width just to fit in the window-groove preferably,
its length being somewhat less than the width of the window, with telescopic sections 1 and 2 at the ends adapted to slide intothe vertical grooves of the window-frame. A flange 3 at the top engages the edge of the window-sash B. An opening 4 in the rear surface of the box is provided to receive the external air, the entrance of which and its discharge into the room being controlled by a door 5, which latter is constructed by cutting the corners of the lower edge a certain distance, allowing it to enter the opening 6 and extending it inwardly and downwardly a sulficient depth to act as a hinge and preventing the rain from beating in under the lower part of door 5. When attached, this door may, however, be hinged removably by means of the inwardly and downwardly curved flange 12 entering the opening 6 and resting on the lower edge thereof, or it may be permanently hinged at its lower edge to the lower edge of the opening 6 in front of the box. The ends 7 7 of the door prevent the escape of air at such points, and these ends are provided with flanges'8 8, which limit the outward swing of the door, whereas the flange 9 around theupper edge and two ends of the door are in position to strike the surface of the box and limit the inward movement of the door when the ventilator is closed. The ends 7 7 have sufficient frictional engagementwith the ends of the opening 6, so that the door is held at different angles by reason of this frictional contact. When closed, the knob 10 may be turned until the catch 11 engages beneath the edge of the adjacent metal portion of the box A. In this way a very simple ventilator is provided, and one which may be adjusted to regulate the amount of air to be admitted, and this air under all conditions is discharged upward, so that objectionable drafts to the occupants of the room in which the ventilators are used are avoided.
It is evident that slight changes might be made in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the exact construction herein set forth; but,
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a removable window-ventilator, the combination withabox having opposite alined openings in its front and rear walls, of ex tension members telescopically received within'the box, and a door for closing the rear opening of the box, the door removably supported upon the rear wall of the box, means for limiting the outward movement of the door and a continuous offset flange depending below and extending entirely across that portion of the door which engages the rear wall for preventing the entrance of rain through the rear opening in the box, the flange or lip lying inside the hollow box.
2. In a removable window-ventilator, the combination with a box having alined openings in its front and rear walls, of a door removably supported in and adapted to close the opening in the rear wall, an offset flange or lip extending practically entirely across the lower edge of the door and depending beneath that portion of the door which rests upon the edge of the opening in the rear wall of the box for excluding moisture, wings carried by the door and frictionally engaging the walls of the rear opening to retain the door in any position to which it may be moved and longitudinally and oppositely extending flanges projectingvoutward from and at right angles to the wings for engaging the inner face of the rear wall to limit the outward movement of the door.
3.- In a removable window-ventilator, the combination with a box having alined openings in its front and rear walls, of telescopic extension members receivable within the box,
box to limit the outward movement of the door.
In testimony whereof I afiix my signature in presence of two witnesses.
HENRY O. REESE.
