ROLLER-SCREEN.

SPECIFICATION forming part of Letters Patent No. 767,644, dated August 16, 1904. Application tiled September 25, 1903.v Serial No. 174,540A. (No model.)

To all whom it may concern.:

Be it known that I, MAURICE FRANK HUTCH- IsoN, a citizen of the United States, residing at Floris, in the county of Fairfax and State of Virginia, have invented new and useful Improvements in Roller-Screens, of which the following is a specification.

My invention relates to screens for windows,

and controlled by the raising and lowering'of v the window-sash that will insure the exclusion of iies and other insects by maintaining the screen in close contact with the windowframe.

A further object of the invention is to provide a rolling screen that may be'readily applied to an ordinary window-frame without altering the construction of the latter and remolved without defacing the window frame or sas I.

A further object of the invention is to provide improved means for attaching the screen to the sash and generally to improve the details of screens of the type referred to.

With these ends in view the invention consists of the features of construction hereinafter fully described, and illustrated in the accompanying drawings, which form part of this specification.

In the drawings, Figure 1 is a view in perspective of a portion of a window frame and sash with Iny improved screen applied thereto, the cover for the screen being removed. Fig. 2 is a perspective view showingthe adjustable guard employed in connection with the screenroller andthe lower ends of the strips which support the guard and roller. Fig. 3 is a view in perspective of the telescopic cover for the screen-roller. Fig. 4 is an elevation, partly in section, showing the screen rolled and the sash in lowered or closed position. Fig. 5 is a detail perspective view of one `end of the screen-supporting strip, showing the manner of securing the screen material thereto and also illustrating one of the linger-pieces for;

raising and lowering the sash and for detachably securing the screen-strip to the sash. Fig. 6 is a vertical section of the lower rail of the window-sash and screen-roller, showing the manner of suspending the latter. is a perspective view of one of the springcatches employed for securing the sash at different adjustments. Fig. 8 is a detail perspective view of the upper end of one of the guide-strips with its catch-button for securing the strip to the window-frame, and Fig. 9 is a detail view of the lower portion of one of the guide-strips.Y

The reference-numeral 1 designates a Window-frame, and 2 the sash, both of which are of the well-known construction in common use. To each side of the frame 1 is detachably secured an angle-strip 3, said strips beingformed with keyhole-slots 4, as best shown in Fig. 8, to receive headed pins 5, projecting from the inner surfaces of the frame. Adjacent to one or more of the slots 4 is a pivoted catch-button 5a, which serves to retain the headed pins in the narrow portions of the slots, thus irmly securing the strips in place, but permitting them to be readily removed when Fig. 7

the catch-button is turned away from the pin.

One of the angle-strips 3 is formed along its inner edge with a series of notches 6, adapted to be engaged by a spring-catchl of the form shown in Fig. 7 comprising a dog 7, pivotally secured to the lower rail of the sash, as shown in Fig. 1, and a spring 8, bent around the pivot of the dog at one end, then extending upward through an opening 9, and terminating in a loop 10, by means of which the dog is pulled out of engagement with the notched strip. rlhe upper portion of the dog is preferably bifurcated to adapt it to straddle the edge of the strip.

It will be apparent that the sash may be secured at any desired adjustment by the means thus described and readily released and lowered.

rIhe numeral 11 designates astrip, preferably of wood, divided diagonally its entire length, as indicated at 12, between the two sections of which is secured the upper edge of the screen 13, the two sections of the strip then being securely7 fastened together, as by gluing, tacks, or otherwise. As clearly shown in Fig. 5, this manner of securing the screen to the strip brings the screen flush with the inner side of the strip and in close contact with the window-frame when the sash is raised.

Upon the strip 11 are adjustably secured two linger-pieces, which serve the double purpose of means for raising and lowering the sash and means for detachably securing the strip 11 to the window-sash. Each of these finger-pieces comprises a curved arm 14:, having a perforation 15 and a slide 16 conforming to the cross-sectional shape of the strip. The perfor-ations 15 receive pins projecting from the sash-rail, and the manner of securing the finger-pieces upon the slide permits them to be adjusted thereon without removal therefrom, if desired.

The lower edge of the screen 13 is secured to a roller 17, one end of which is bored out to form a seat for a spring 18 and pintle 19, while the opposite end of the roller is provided with a pintle 20, supported in a bearing 20, formed in the adjacent strip 3. The spring' 18 when in a relaxed condition is somewhat larger in diameter than the hollow portion of the roller 17 and before being placed in position therein is wound very tightly, so as to be under a high tension, thereby bearing against the inner walls of the roller, and the roller being suspended in the bearing 21 of the swinging arm 22 and the elongated bearing 20 will thus by the action of the spring as the screen is unwound be gradually forced back and always in contact with the guard 23. rlhe projecting end of the pintle 19 is squared to fit a slot 21, formed in the end of an arm 22, the upper end of which is pivotally attached to the adjacent strip 3.

In rear of the roller 17 is located a guard 23, preferably com posed of telescopic sections to adapt it to be adjusted to lit windows of different widths and having end lugs 24 fitting within keepers 25 on the guide-strips 8. The function of this guard is to close the space below the roller, as illustrated in Fig. 6.

The screen-roller is concealed by acover 26, comprising telescopic sections curved to conform to the position of the roller and adapted to be suitably supported between the guidestrips.

rlhe operation of the mechanism as above described will be readily understood, the spring 18 being so adjusted that when the sash is closed and the screen rolled up there will be little or no tension on the spring; but as the sash is raised the tension on the spring will increase, so that any movement of the sash in a downward direction will cause the screen to wind automatically.

A distinguishing feature of my construction of roller and spring is that the spring is so wound as to entirely fill the bore of the roller,

spring-catch for sustaining the sash may be' omitted.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. rl`he combination with a window-frame, of a roller, an elongated bearing for one end thereof and a pivoted arm provided with a bearing for the opposite end, a screen attached to the roller, aguard in rear of the roller and a coil-spring adjusted under tension within one end of the roller, substantially as described.

2. A rolling window-screen, comprising a supporting-strip having an inclined lierf or slot, a netting secured at its upper edge within said lzerf or slot, a spring-roller to which the roller edge of the netting is attached and means for securing said strip to a window-sash.

3. A rolling window-screen comprising a supporting -strip divided diagonally of its length, anetting having its upper edge secured between the two portions of said strip, a springroller to which the roller edge of the netting is attached and linger-pieces laterally adjustable on without removal from said strip for securing the same to a window-sash.

4. The combination with a window-sash and a screen-roller, of an adjustable guard arranged in the rear of and adjacent to but not connected with said roller.

5. The combination with a window-frame,

of angle-strips formed with keyhole-slots,-

means for detachably securing said strips to the frame and a catch-button on said strip adjacent one of said slots for locking the strips in position.

6. The combination with a window-sash of a rolling screen having a suspending-strip at its upper edge and linger-pieces adjustable laterally on without removal from said strip for raising and lowering the sash.

7. The combination with a window-frame, of angle-strips formed with keyhole-slots, means for detachably securing said strips to the frame, a catch-button for locking said strips in place, a screen-roller and a guard mounted in bearings in the lower ends of said strips in rear of and adjacent to said roller.

8. The combination with a window-frame, of angle-strips formed with keyhole-slots, a catch-button on said strips adjacent one of said IOO IIO
