Application filed July 26, 1924. Serial No. 728,310.

. prevent the window from rattling.

A further object of the invention is the production of a guideway of the type spec1 fied which shall also have the function of urging the window upwardly and acting as a counterbalance therefor.

' lVith the above and otherobjects in view the invention consists in the novel device hereinafter described and then specified in the claims.

In the accompanying drawing showing a practical embodiment of the invention:

Fig. 1 is a front elevation of-a window frame and window.

Fig. 2 is an enlarged section taken through I one of the side members of the frame.

Fig. 3 is a transverse section taken through one of the side members and a part of tie window.

Fig. 4. is a view similar to Fig. 3 butshowing a slight modification. Referring in detail to the several figures of the drawing:

1 indicates the side members of a window frame, while 2 and 3 indicate the upper and lower members thereof. Said side members are each provided with a channel 4. The window itself which may be either a framed or frameless ane is indicated at 5 and is provided at he lower edge thereof with a U-strip 6 in which the window is seated and to which it is secured in any manner, said strip also having fastened thereto a downwardly depending slotted plate 7. The U- shaped strip 6 is provided with an extension 8 at either end projecting within the channels 4.

of a pivoted. operating arm 12, the end of which is provided with a roller 13 engaging wlthin the slot of the plate '7.

In each of the channels 4, I locate a long scpl ared spiral spring 14 the outer side of w 1ch is inwardly rounded or depressed as indicated at 15. The upper ends of said springs are secured to the upper wall of said channels while the lower ends are fastened tothe extensions 8 of the U-strip 6. The sides of the window 5 slidably engage within the rounded or "depressed portion 15 of said springs. Said springs therefore, not only provide supporting guideways forthe window but inasmuch as they are fastened thereto in the manner described they are constantly exerting an upward effort on the window and in consequence assist in the raising thereof. F urtherinore they prevent the window from rattling irrespective of its .position.

The window may be raised and lowered by rotation of the crank or handle 10 where by the operating arm 12 is caused to swing on its pivot, the' roller 13then sliding the upwardly or downwardly depending on the direction of rotation given the crank: or handle. is old in the art, however, and forms no part of the present invention.

In the modification illustrated in F ig. 4: the ends of the channels are bent inwardly toward the window as indicated at 16 this acting to prevent the springs from becoming dislodged from their proper position.

lVhat I claim as my inventionis:

1. Ina window, a guideway therefor in which the window is vertically slidable, said guideway being adapted to exert an upward effort on said window.

2. In a window, a guideway therefor C0111- prising a spiral spring on which the window is vertically slidable, said guideway acting to exert an upward eflort on said window.

3. In a window, a guideway therefor engaging the side of the window and in which the window is vertically slidable, said guideway acting to counterbalance the weight of the window.

4. In a window, means for raising and lowering the same and a guideway receiving the side edge of the window and acting to assist in the raising operation thereof.

5. In a window, a U-shaped channel, a

slot of the plate 7 and forcing the window This operating mechanism per se spring in said U-shapedchanne1 engaging the window and on which said window is slidable, said spring acting also to assist in ablew" 7. 'In a window, a U-shaped channeland a spring therein fastened to said channel and to the window, said window being slidablo on said spring. I 1

8. In a window, a channel, a window having an extension extending within said channel and a spring fastened to said channel and to said extension and on which the win- .dow is slidahle vertically.

9; In a window, a U-shaped channel, a

spring therein fastened to the window and.

to said channel and on which said window is slidable, said channel having its free ends turned inwardly towards the window.

10. In a window, a guideway therefor in which the window is vertically slidable, said guideway being adapted to exert an upward effort on said window and means for raising and lowering said window.

11. In a window, a U-shaped channel in which the window is vertically slidable, a U-shaped strip fastened to the lower edge of the window and a sprin in said channel fastened thereto and to said strip and exerting an upward eifort'on said window.

12. In a window, a window frame provided with U-shaped Channels therein in which the window is slidable, a' U-shaped strip fastened to the lower edge of the window, a spring in said channel fastened to the upper end thereof and to-eaid strip and exerting an upward eifort on said window.

Signed at New York in the county of New York and State of New Yorl; this th day of July A. D. 1924.
