Application filed August 15, 1924, Serial No. 782,291, and in Canada larch 22, 1924.

This invention relates to improvements in windows and the objects of the invention are to provide an e-flicient and weather-proof window havin counter-balanced sashes, piv otally mounte on carrying bars, whereby the. window can be easily swung inwardly to .be cleaned on both sides from within.

Further objects are to rovide an improved window of this descnption, provided with means for locking the sashes-when set at an angle for ventilation and swung inwardly for cleaning.

Further objects are to provide a window of this class in which suitable supporting F means are included for the sashes, when swung inwardly. I

Yet a further object is to provide a window of this character having in combination with the .sills, the carrying bars and the sashes, an adjustably mounted weather stri whereby the window is rendered absolutely wind-proof.

A still further object is the provision of a window, embodying the above and other improvements, that can be manufactured and placed on the market for practically the same price as the ordinary window without any improvements.

With the foregoing and other objects in view, the invention consists essentially in the novel construction and" arrangement of parts, described in the present specification and illustrated in the accompanying drawings that form part of the same.

Referring now to the drawings in which like characters of reference indicate corresponding parts in eachfigure:

Figure 1 is a front elevation of an embodiment of my improved window, fromthe inside, with sashes closed.

Figure 2 is a vertical section, with sashes closed.

Figure '3 is a' vertical section with the lower sash raised and swung inwardly. The dotted lines indicate the inward position of the upper sash when. swung inwardly.

Figure 4 is a cross sectlon with window down.

Figure 5 is a sectional detail, showing the connection between the window'sashes and the frame, with the weather strip.

Figure 6 is a per ective view of the carrying bar detached om the window Figure 7 is a sectional detail showing the reinforcing plate for the carrying bar.

Figure 8 is an enlarged section on line 88 of Figure 1.

Figure 9 is an enlarged fragmentary section through the adjustable weather strip.

FigureIO' is a perspective detail of the weather strip.

Figure 11 is a section. on line 1111 of Figure 3.

In the drawings A designates an embodiment of my improved window as a whole, comprising a rectangular frame, of any well known construction, formed of sides 10 and 11, top '12 and base or sill 13. Within this frame are mounted, as hereinafter more fully described, the. top and bottom window sashes 14 and 15. v

Referring now more particularly to Figures 2 and 3, it will be seen that'the sashes 14' and 15 counter-balance one another and that they are pivotall mounted at their lower ends at 16 and 1 on carrying bars 18, these carrying bars being designed to travel upwardly and downwardly in channels-19 and 20 respectively, formed in the sides of the window frame and separated by a stop 21. These carrying bars 18 are connected to one another by means of a flexible cable or rope 22 secured at each end to hook members 23 in the top of said bars, the cable being designed to travel over a pulley 24 mounted in the extreme upper end of the stop member 21 and whereby the bars. and the window sashes, pivotally carried there'- by, are counter-balanced.

From the foregoing it will be seen the operation ofthe WllldOW, so far, will be self-- evident; on the upper sash 14 being moved downwardly'the lower sash 15 counter-balancing it will move upwardly and vice versa.

To provide draft-proof ventilation and also to lock the window in 0 en position,.I provide catches 25 on the insi e of each sash, these catches being designed to engage with orifices 26 in the carrying bars 18. Furthermore to support the window sash, when 100 swung inwardly for cleaning 'purposes, at any required angle, I provide-supportmg buffers 27 of any suitable material, in the sides of the frame, or if required in any other desired or more suitableplace, for in- 105 stance on the bottom or sill of the frame, these buffers being designed to support the window for cleaning it on both sides and for retainin the window at any angle required and wit out danger of its becoming discon- 11 bination with and adapted to fit into 'verti-. cally extending grooves or slots 29 in each of' the channels 19 and 20. The formation of this strip enables it topractically embrace the top and bottom of one side of the carrying bars and to slidably engage therewith. The opposite side of this strip to that engaging the groove 29 is designed to engage with a groove 30 in the window sash, thus form ing a complete wind-proof means in combi-' nation withthe frame and the window sash.

Another essential feature of my weather strip is that instead of being fixedly secured to the stop 21, it is adjustably or movably secured thereto, so that it can move inwardly and outwardly, this being arranged by-having openings 31 through the strip and into which the securing means extend, of larger size than said securing means.

Another and further improvement in regard to this strip is that it may also be suitably secured on the carrying bar'itself, while at the same time adapted to simultaneously engage with the groove 29 in the window' frame, and the groove on the sash 30.

Referring now more particularly to the catches 25, on the inside of each sash, as illustrated moreparticularly in Figure 8, it will be noted that they are preferably provided with actuating springs 25 for the bolts or catches 25, adapted to engage with orifices 26 in the carrying bars. When it is desired to securely lock the windows in ventilating position the catches 25 are designed to engage with orifices in the carrying bars registering with orifices in the window frame so that any movement of the window sash is completely prevented. a

The pivotal means by which at 16 the sashes are pivotally mounted on the carry ing bars 18, consist of similar sprin -actuated catch members to those alrea y de scribed and designated by the numeral 25 and are embedded-in the base of each of the window sashes anddesigned to engage with each of a series of openings, plates pro- .tected in the carrying bars. 32 are reinforcing plates for the carrying bars.

As many changes could be made in the above construction and many apparently widely different embodiments of my invention, within the scope of the claims, con structed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawings shall be interpreted as illustrative and not-in a limitingsense.
