rlhis invention relates to window sashes and particularly to what are known as revolving 'sashes; and the object of the inven-` tion is to provide an improved manner of supporting and guiding the sash frames in the window frame and especially the supplemental sash bars which are movable `with respect to the bead and parting `strips of the window frame; a further object being to providethe .opposite sides of the sasheswith supplemental rails in connection with which the sashes` are pivotally supported and `to the provision of projecting flanges on said supplemental rails cooperating with the parting strip of the window frame to form a pivotal mounting of said rails with respect tothe window frame facilitating the free and easy action of the sashes in the frame and readily adjusting and fitting the sashes to the window frame; a `further object being to provide means on the upperand lower sashes for preventing accidental opening of the sashes when in closed position; a still further object being to provide iiieanson` the pivots of said sashes for .coupling the counterbalance weight chains orV cords therewith; andwhith these and other objects in View, the invention consists in a window sash of the class and for thepurpose specied which is simple in construction, eiiicient in use` and which is constructed as hereinafter described` and claimed. j i j `The invention is fully disclosed in the following specitication, of which the accompanying drawings form a partin which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which .j Fig. 1 is aninside view of a window frame showing oneof the sashes in a partially open position.

Fig. 2 is a longitudinal, sectional view through the frame and sashes shown in Fig. 1.V Fig. 3 .is a transverse, sectional view through one side of the window frame and through part of two Lof the sashesmounted therein, showing the pivotal mounting of one sash. i Fig.` 4 is a view similar to Fig. 3 indicatingone of the sashes in a swung position.

Fig. 5 is an end view of the central portion of one sash indicating the manner of attach- Ving the counterbalance chain therewith.

F ig. 6 is an enlarged, sectional and side View of the lower corner portion of the bote' tom sash illustrating a latch device which I employ; and, Y j

Fig. 7 is a partial section on the line 7-7 of Fig. 1, showing a stop employed in conneet-ion with the top sash.

In the drawings, I have indicated at 10 a window frame of any desired form and construction. At 11, I have shown the lower sash; '12 the upper sash mounted to move vertically in the frame 10 in the usual channels or guideways formed by the inner and outer bead strips 13 and 14C and the central parting strip 15.

The sashes 10 and 11 may be composed of wood as illustrated in the accompanying drawings or of any other desired construction commonly known in the art. The side rails of the upper and lower sashes include

supplemental rails

16 and 17 respectively. The

Vrails

16 and 17, in the construction shown, are formed from sheet metal and are of channel, cross-sectional form,the crosshead of each rail having arranged longitudinally thereof an outwardly pressed arc-shaped bead 16a-17a seating in a corresponding groove .formed in the outer surfaces of the side rails of the sashes to normally key and retain theisashes against swinging movement with respect to the rails. The central portions of the sasl-ies Yare pivoted to their respective rails by screws 18 secured to the side rails of the sashes 11 and 12, and the heads 19 of which are disposed in the chan nels of the

rails

16 and 17. Mounted on the screws adjacent the heads thereof are large washers or plates 20 Awhich forni seats for coil springs 21 which are disposed between said plates and the crosshead of the rails, and normallyserve to vhold .the sashes in tensional engagement with the rails as will be apparent. 9

It is also preferred that the washers or plates 20 include upwardly extending hooks 22, `by means of which the chains or cords 23 of counterbalance weights may be attached to the' resepective saslies.`

ino

One side flange 24-24ta of each rail 16-17 respectively is arranged at right angles to the crosshead and adjacent the bead strips 13 and 14 as clearly seen in F ig. 3 of the drawings, said flange terminating short of the base of the channel formed between the bead strips and parting strip, whereas the other flanges 25, a, of the

rails

16 and 17 respectively are fashioned to form outwardly projecting beads 26-26a which overlie the inner faces of the parting strip 15 to facilitate the mounting and fitting of the sashes within the window frame and also to form of the corner portions 26?), note Fig. 7 pivots which can act upon the corner portions 15a. of the parting strip 15 to permit slight, swinging movement of the

rails

16 and 17 within and between the parting strip and the outer beaded strips 13 and 14E in the operation of swinging the window sashes upon the pivots and with references to the

rails

16 and 17, it being understood that the grooved portions of the side rails of the sash tensionally pass over the beads 16a-17a in this operation.

I also prefer to employ at the upper ends of the rails 17 and on the outer surfaces thereof, inwardly projecting stop lugs 27, which are formed from the material of the rail and operate in conjunction with the outer faces of the side rails of the sash 12 to limit outward swinging movement of the upper end of said upper sash.

It will be understood that the upper sash may be swung into the position shown in Fig. 2 of the drawings by exerting outward pressure on the lower portion of the upper sash; and this sash may be moved into various, anguiar positions to give the desired ventilation and also to facilitate the cleaning of the window pane of the sash. The lower corner portions of the lower sash 11 are each provided with latch or catch devices in the form of a pin 28 adapted to pass into an aperture 29 at the lower endof the rail 16, the pin being moved into operative and inoperative positions by a handle member 30 exposed on the inner face of the sash. Each of these devices is of similar construction, and the brief description of one will apply to the other.

These catch devices are adapted to lock the lower sash against swinging movement when in closed position, and by releasing these catch devices, the lower sash may be swung on its pivot in the rail 16 into different angular positions with respect to the window frame for the purpose of ventilation and for the further purpose of cleaning the outer surface of the window panel.

It will be understood that the length of the supplement-

al rails

16 and 17 is equalto or substantially equal to the length of the side railsof the sashes 11 and 12, and that said rails are movable in and between the bead strips and parting strips at opposite sides of the window frame in the operation of raising -ment of the sashes on their pivots. It will be understood that while I have shown certain details of construction for carrying my invention into effect, that I am not necessarily limited to these details, and various changes in and modifications of the construction herein shown and described may be made within the scope of the appended claims without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is
