GERALD c. FIELD AND ABRAM H. ALBERTSON, or SEATTLE-WASHINGTON.

WINDOW-VENTILATOR,

Application filed November 25, 1913.

To aZZ whom it may concern Be it known that we, GERALD C. FIELD and ABRAM I-I. ALBERTSON, citizens of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in l/Vindow-Ventilators, of which the following is a specification.

This invention relates to window-ventilators; and its object is the provision of a simple and inexpensive device of this character which will be convenient to use and efficient in operation.

The invention consists in the novel construction and adaptation of parts, as will be hereinafter more fully described.

In the accompanying drawings, forming a part of the specification, Figure 1 is a perspective view of a portion of a window showing our improved ventilator in operative position therein. Fig. 2 is a transverse vertical section of the same. Fig. 3 is a similar view illustrating the ventilator in inoperative position.

Referring to the drawings, the reference numeral 5 indicates the lower rail of a window sash which is vertically movable in ways provided in the jambs 6 of a window-frame. Stops or strips, such as 7, are secured to said jambs to serve as guides for the ways.

8 is the window-sill with a recess having a sloping surface 9 to afford the so-called wash and against which the sash is lowered in closing the window. As illustrated a ledge-board 10 is provided upon the sill and constitutes a part of the latter.

The above-mentioned parts are or may be of the usual or suitable construction.

According to our invention, we provide a bar 11 of a length to enter the space between the window-frame stops 7. Said bar is formed with a rabbet 12 along one of its edges to provide two faces 13 and 14 arranged in substantially rectangular relations to fit against the outer and upper surfaces 15 and 16, respectively, of the sill ledge 10. 17 represents hinges secured to the face 14 of the bar and the face 16 of said ledge whereby the bar may be swung down into the position in which it is shown in Fig. 3 or restored to the position which it occupies in Fig. 2. Diagonally opposite the rabbet 12 the bar is provided with a rabbet 18 to receive the corner of the sash-rail 5 when the Specification of Letters Patent;

latter is lowered upon the bar when the sameis in its operative position, as shown 1n Fig. 2. Alr ducts or slots 19 are provided in the bar and are arranged to incline downwardly from a recess 20 in the inner side of the bar to the outer side 21, as shown. The recess 20 furnishes means whereby the fingers of the operator may be introduced below the bar for turning the same up.

To employ the device, the bar is first tilted up into upright position (Fig. 2) and the window-sash moved down thereupon to have its lower rail 5 engage the same within the rabbet 18. The air is free to enter a room through the ducts 19 and, by reason of the inclined disposition of the ducts, the air is directed upwardly to create currents for efiective ventilation. To cause the ventilator to become inoperative the windowsash is first raised from the bar 11 and the latter is swung down upon the window-' to have the lower rail thereof closed against the sill-wash 9, as shown in Fig. 3.

The invention is remarkably efiective as a ventilator, and is readily transposed from operative position into inoperative position, or vice versa.

What we claim as our invention, is-

1. In a device of the character described an integral bar being substantially rectangue lar in cross section, said bar being ,of such length as to extend across a window sill and having its diagonally opposed edges cut away to form recesses, the upper of which is adapted to receive the lower edge of a window sash and the lower of which is adapted to receive the edge of a window sill, said bar having openings formed transversely and diagonally therethrough and means for hinging said bar to a window sill, said hinging means being located at the juncture of the inner wall of a building and the lower cut out portion of said bar.

2. In a device of the character described an integral bar being substantially rectangular in cross section and of such length as to openings formed transversely and diago- Signed at Seattle, Wash, this 17th day of naly therethrough and means for hingingr November, 1913.
