3 Claims.

This invention relates to window frames and sashes.

More especially this invention pertains to a window frame having a pair of vertically sliding 6 sashes together with a easement window for each sash. A window of this type has advantages over other types of windows such as ease in cleaning, full opening, and the choice of opening any part of the window to any desired degree,

10 together with a neat appearance.

We are aware that windows of this type have already been invented. This invention is an improvement over our patent on Window of August 15, 1933, Patent No. 1,922,505.

One of the principal objects of this invention is to provide more simpliiied, yet eiiicient windows of this type.

A further object of this invention is to provide a metal frame tted with weather sealed sliding metal sashes, each of these sliding metal sashes provided with a Casement sash hinged thereto and constructed so as to form an ei'licient weather seal when in a closed position.

A further object of the invention is to provide oppositely disposed flanges along the Vertical edges of the sashes together with oppositely disposed channels to which the oppositely disposed flanges slide.

A further object is to provide a weather seal for the lower edge of the lower sash together with a weather seal for the upper edge of the upper sash.

It is also pointed out that the structure of this window provides for a pair of slidable sashes with Casement sashes hinged thereto and mounted in such a manner that it is possible to open both easement sashes at the same time and in addition to that allowing for the movement of the slidable sashes up and down the frame so that the upper slidable sash may be moved to the lower part or" the frame while the lower slidable sash may be moved to the upper part of the frame in order to provide easy Yand convenient means for cleaning the windows.

4 5 A stillfurther object is to provide a window comprising a window frame having a pair of slidable sashes and a pair of easement sashes contained therein, these sashes counterbalanced so that the necessity for sash weights ordinarily used is eliminated. Another advantage of a Vwindow of this type is in providing means for placing a number of windows in close relation to each other through the elimination of space ordinarily necessary for the weights.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described andV claimed, it being understood that changes in the precise 5 embodiment of the invention herein disclosed, can be made within the scope oi what is claimed, without departing from the spirit or' the invention.

The invention is illustrated in the accompany- 10 ing drawings, wherein:-

Figure l is a front elevation of the device.

Figure 2 is an enlarged cross section taken on line 2-2 of Figure 1.

. Figure 3 is a perspective View showing a cross 15 section through the frame of the window so as to disclose an outer edge of the upper and lower slidable sashes.

Figure 4 is an enlarged cross section taken on line of Figure 1. y

Figure 5 is an enlarged detail view of a weather seal strip.

Figure 6 is a detail view of Figure 4 showing an enlarged portion oi a glass securing strip.

Figure 7 isa perspective View of the upper slid- 25 able sash with easement window in an open position.

By referring to the drawings it will be seen that there is provided a metal window frame I.

Slidably maintained within this window frame I 30' there is an upper slidable sash 2 and a lower slidable sash 3. By referring to Figure 2 it will be seen that these sashes 2 and 3 are held in slidable relation to the frame I by means of a blind stop ll, a window stop 5, and a parting strip 6, al1 of 35 which are held in position by means of screws 1. t will be seen that the vertical edges of the slidable sashes 2 and 3 are provided with oppositely disposed flanges 8 and 9. The inner flanges 9 are each slidably maintained within a channel 40 formed by the T--shaped parting strip 6 and the frame I, and the flanges 8 are slidably maintained within channels formed by projections I0 of the blind stop ll and the window stop 5, together with the window frame I. It will be seen that the 45 inner side of the frame I is provided with a indow trim I I.

By referring to Figure 4 it will be seen that the upper horizontal part of the frame I is provided with a iillet stop I2 which is provided with down- 50 wardly extended portions i3 and I4, thus forming a recces into which fit-s the upper edge of the upper sash 2. It will be seen that this upper edge of the sash 2 is provided with a semi-circular channel I5, thereby forming window sealing pro- 55 jections I6. It will also be seen that the sashes 2 and 3 are formed with flanges I1 at right angles to inner edges I8. It will be seen that in the inner corners of the angles formed by the iianges I1 and inner edges I8, there is provided a weather channel I9. It will be seen that the lower horizontal portion of the upper sash 2 is provided with an outwardly extending flange 20 to which is secured a meeting rail 2|. This meeting rail 2| is provided with an angular notch 22 into which iits an outwardly extending horizontal flange 23 formed on the upper edge of the lower sash 3.

It will be seen by referring to Figures 4 and 5 that there is provided a weather drain and seal 24 which is semiecircular in form and which is attached to a window sill 25. The lower edge of the lower sash 3 is provided with a semi-circular recess which ts over the window drain and seal 24 when the lower sash 3 is in a closed position. This weather drain and seal 24 is provided with an upper drain channel 26 and lower drain channels 21. The lower drain channels 21 are connected by transverse channels 28. It will also be seen that there is attached to the sill 25 a window stool 29 and an apron 36.

By referring to Figures 2, 4, and "I it will be seen that there is provided hinged casement sashes 3| hinged to the sashes 2 and 3 by means of hinges 34. These hinged casement sashes 3| are essentially formed of angle material and are each provided with an outwardly extending weather seal flange 32 which covers the inner perimeter of the ange I1. It will also be seen that at the outer corners of the hinged casement sashes 3| and adjacent to the weather channel I9 there is provided a drainage channel 33. It will also be seen that a glass 35 for each of the casement sashes 3| is held in position by means of a glass securing strip 36 provided with a relatively short rib 31 and an inturned flange 38. This glass securing strip 36 is held in position by means of screws 39.

By referring to Figure 3 it will be seen that the upper sash 2 and the lower sash 3 are counterbalanced by means of a cord 4@ which passes over a pulley 4|. One end 42 of this cord 40 is attached to the upper sash 2 and the other end 43 is attached to the lower sash 3. It will be noticed that semi-circular recesses M in the vertical edges of the sashes 2 and 3 provide space for the carrying of the cord 40. In the construction of buildings using a plurality of windows adjacent to each other space can be saved between the windows by using this particular construction.

By referring to Figure 1 it will be seen that there is provided latches 45 for the purpose of latching the casement sashes 3|. It will also'be seen that there is provided a second latch 46 for the purpose of holding the upper sash 2 and the lower sash 3 in a locked position when closed.
