PATENT OFFICE ES MOND I. WILEY, 0]! SAN FRANCISCO, CALIFORNIA, 'ASSIGNOR 'IO UNIVERSAL WIN- DOW GOIPANY, OF OAKLAND, CALIFORNIA, A CORPORATION OF CALIFORNIA AWNING TYPE WINDOW OPERATOR Application filed January 29, 1930. serial No. 424,222.

This invention relates to apparatus for operating awning type windows.

Hitherto, school and like buildings have been fitted with awnin type windows unequipped with mechanism connecting the sashes together so that the sashes would opcrate in unison and consequently thesashes had to be operated individually by a window pole. This, v of course, is entirely unsatisfactory and therefore it is the principal ob ect of the present invention to provide a simple and inexpensive apparatus which may be aplied to awning type windows without altermg their construction and which enables all of the sashes to be operated by the operatlon of the lowermost sash which also may be operated independently of the others.

In carrying the invention intov practice, I connect the sashes together by means of an operating rod to which the lowermost sash 1s latched, so that by operation of the lowermost sash all of the sashes may be manipulated. By releasing this latch, however, the lower sash may operate independently of the other sashes.

One form which the invention may assume is exemplified in the following descr ptlon and illustrated by way of example in the accompanying drawing, in which:

Fig. 1 is a view in vertical section through an awning type window equipped with my improved apparatus.

Fig. 2 is a fragmentary view in elevation showing the mounting of my apparatus on the window.

Fig. 3 is a view similar to Fig. 1 showing. the apparatus mounted on the window w1th the sashes in closed position.

Fig. 4 is a fragmentary view in plan section showing the connection 'between the operating rod and the sash.

Referring more particularly to the accompanying drawing, 10 indicates a window frame wherein three sashes 11 are mounted. This window is of the awning type and for this reason the upper ends of the sashes are pivotally and slidably connected to the frame. This connection includes shoes 12 pivoted to the sashes at the sides thereof and guided for vertical reciprocation in guide grooves 14 which are disposed between the sides of the I sashes and the frame and which are pivoted at one end to the frame and at the other to the sashes. The point at which the fulcrum links connect with the sashes is intermediate the ends of the latter so that the sashes will swing in a vertical plane as illustrated in the drawing.

The present invention, however, is particularly concerned with a mechanism for operatlng the sashes. Th1s mechanism lncludes a pair of brackets 16 for each sash. These brackets are fixed one at each side of the sash at the upper end thereof and project inwardly as illustrated. A vertically reciprocable operatin rod 17 is arranged at each side of the win ow. Connectors 18 are adjustably mounted on these rods and are pivotally connected to adjacent brackets 16 so as to operatively connect the rod to the upper sashes. Due to these connections it is obvious that the upper sashes will operate in unison.

At the lower end of each rod a sliding connector 19 is provided which is pivoted to the the adjacent'bracket 16 on the lower sash. On each rod 17 just below the sliding connector 19 is fixed a latch support 20 which is vertically adjustable on the rod. This latch support 20 is fitted with a pivotal latch bolt 21 which is adapted to cooperate with alatch bolt keeper 22 formed on the sliding connector 19. The latch bolt is pivotally connected with the latch support 20 and is yieldably maintained in latching position by a spring 23. The latch bolts 21 at opposite sides of the sash are connected together by a chain or cord 24 so that by pulling downwardly on the cord both latch bolts 21 may be released simultaneously. When the latch bolts are released the lower sash is free: to swing independently of the upper sashes.

In operation of the device, assuming that the sashes are closed and that the latch connections between the lower sash and the rods are effective, opening movement of the lower sash will, of course, be accompanied by downbrackets 16 the upper sashes will swing in unison with the lower sash.

As it is often desirable that the lower sash be closed while the upper sashes are open after the sashes have been opened in order to close the lower sash without effecting the position of the upper ones, it is only necessary to exert a pull on the cord or chain 24 and release the latch connection between the lower sash and the operating rods. The lower sash may then be closed without efi'ecting the position of the operating rods 17.

To close the upper sashes it is only necessary to open the lower sash to a position where the latch bolts 21 will engage the latch bolt keepers 22 and reconnect the lower sash to the operating rods 17. Closing of the lower sash will then, of course, be accompanied b upward movement of the operating rods and consequently of the upper sashes.

By making the connectors 18 adjustable on the rods 17 is important because it enables a perfect adjustment to be obtained between the sashes so that they will all close tightly. To further assist in this as previously pointed out the latch supports 20 are also adjustable on the rods 17. Due to these adjustments I am enabled to fit my apparatus to awning type windows and so connect the sashes that they will all close tightly.

From the foregoing it is obvious that I have provided a simple and comparatively inexpensive mechanism which may be applied to awning type windows so that the sashes of the window will operate in unison. Also, my apparatus enables operating of some of the sashes independently of the others.

While I have shown the preferred form of my invention, it is to be understood that various changes may be made in its construction by those skilled in the art without departing from the spirit of the invention as defined in the a pended claims.

Having thus escribed my invention, what .1! claim and desire to secure by Letters Patent is:

1. In combination with an awning type window including a plurality of swinging sashes, an operating rod arranged vertically of the sashes at the interior of the window, connections between the upper sashes and said rod, a latch connection between the lower sash and the rod whereby operation of the lower sash will normally operate all of the sashes, the releasing of said latch connection enabling operation of the lower sash independently of the upper ones.

2. In combination with an awning type window including a plurality of sashes adapted to swing in a vertical plane, brackets at the interior side of said sashes, an operating .rod, adjustable connectors fixed on the opnector reciprocably mounted on the rod and pivoted to the bracket of the lower sash, and operative latch means for latching said sliding connector to the rod.

3. In combination with an awning type window including a plurality of sashes adapted to swing in a vertical plane, an operatm rod'at each side of the window, a pair 0 brackets on each sash positioned one at each side thereof, connectors on the rods pivotally connecting the same to the brackets of the upper sashes, a pair of sliding connectors reciprocably mounted one on each rod and pivotall connected to the brackets of the lower sas latch means for latching each sliding connector to the rod upon which it is mounted, and a connection between the latch means of each rod enabling both latch means to be simultaneously released.

4. In combination with an awning type window including a plurality of sashes adapted to swing in a vertical plane, a bracket fixed to each sash, a bar carried by said brackets and pivotally connected to each bracket whereby movement of said bar will swing all of said sashes in unison, and latch means for releasing the engagement between one of said sashes and said bar whereby said sash may be swung independently of the other sashes.

5. In combination with a window frame and a plurality of sashes pivotally mounted therein means connecting the sashes to cause them all to pivot when one is pivoted,

and means for releasing the connection of one sash whereby it may be pivoted independently, all of said means being supported by the sashes and independent of the frame.
