ALVIN F. NYE, OF ROCHESTER, NET/V YORK, ASSIGNOR Ti FLLBAO TION, OF ROCHESTER, NEXV YORK, A oonrona CORT 3N OF WINDOW SCREEN.

Application filed May 14, 1921, Serial This invention has to do with window screens and relates more particularly to the construction of binding strips or railsfor the same and the means for, connecting the latter to the screen material, the chief object of the invention being to provide a simple, practical and inexpensive construction affording a strong and durable rail with an efficient and convenient means for securely attaching To these and other ends the invention consists certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

22 of Figure 1 showing the construction of the binding strip or rail and the connection of the latter with the screen material.

Similar reference characters throughout the several views indicate the same parts.

The present invention provides an advantageous binding strip or rail for a window screen, in the present embodiment showing the same as applied to a window screen of the type employing a flexible wire cloth or mosquito netting wound on, a spring roller journalled in the window casing. Referring to Figure 1 of the drawings, which illustrates such an application of the invention, there is shown at 5 a window casing with a sill 6, 7 indicating the stops or guide strips for the outer window sash. Fixed on the latter are guides 8 preferably in the form of sheet metal channel members having inner and outer flanges 9 and 10 respectively between which the screen material slides. The screen is wound. on a spring actuated roller 11 journalled at its ends in bearings 12 on the casing, these parts being preferably located in a housing 13 at the top of the casing, the roller turning to wind or unwind the screen material as the latter is raised or lowered by means of a binding strip or bottom rail secured to its lower end.

The wire cloth or netting of which such screens are generally made is relatively still, and as it must be maintained in close fitting engagement with its guides on the window casing to prevent openings through which insects might pass, the screen material offers N0. [169 503 Renewed April 1, a frictional resistance inst sliding movement and requires a substantial binding strip or rail at its lower endv carrying the l dies or other means by which he screen is moved, which rail. must be cap of close engage ment throughout len 'tli w th the window shelf and moreover must be securely connect ed with the screen material to prevent the latter from unraveling at its edge or otherwise becoming torn or discon ectec from the rail. To this end there is preierably provided a rail indicated generally at 15 as formed from a single strip of sheet metal, of substantially channel shape, having an intermediate flat portion adapted for close engagement with the window sill, with an ularly extending

flanges

17 and 18 at its si The flanges extend substantially parallel 1th each other and are preferably corrugated as l9 adjacent the intermediate portion to provide a somewhat resilie t connection to absorb the shock of impact against the window sill, and to strengthen and s'tiit'en the same a5; st lateral binding. As shown in the drawing, the inner flange 17 preferably has its upper or marginal portion curved toward the other flange 18 and bent sharply upon itself as at 20 to provide a projecting ri ge portion, the flange being continued beyond such portion as at 21 for engagement with the other flange and these engaging portions may be securely fastened together if desired, in any suitable manner. The other flange 18 has its marginal portion curved as at 22 to closely embrace the sides of the ridge portion 20 and its edge is turned inwardly of the rail as at 23. These embracing marginal portions of the flanges are preferably so formed as to leave a slight space therebetween and the edge 23 is externally exposed as shown in Figure 2.

The screen material has its lower end inserted between the embracing portions of the flanges, being bent twice upon itself to extend around or embrace the ridge portion 20 vided with handles 24 for moving the same.

As apparent from the construction shown and described, the rail is simple and practical in character, being preferably formed from a single strip of sheet metal which is readily rolled into shape. The rail has sufficient width in cooperation with the screen guides to maintain it in proper alignment uring movement and is adapted to closely engage a window sill and close the window tightly and the character of construction adopted afi'ords a strong and-durable rail capable of withstanding any force necessary to be applied. Combined with this advantageous construction of the rail is the eflective connection described between the latter and the screen material whereby the material is readily attached during assembly and securely engaged and held by the rail at all points over the width of the material and for a suflicient distance from its end as to obviate any danger of its tearing or pulling away from the rail. In addition to these practical advantages, the rail and its method of connection with the screen present a neat and attractive appearance.

I claim as my invention:

1. A binding rail for a window screen comprising an integrally formed substantially channel shaped bottom rail having its intermediate portion at the bottom for contact with the window sill and upwardly extending flanges at'the sides thereof, an upper portion on one of said flanges bent downwardly on itself to form an upwardly projecting a ridge and a downturned edge for attachment to the other flange, and an upper portion on the other of said flanges bent over and closely embracing said ridge with a downwardly extending edge adapted to hold a screen material between said ridge and said embracing portion.

2. A binding rail for a window screen comprising an integrally formed substantially channel shaped rail having its intermediate portion disposed for contact with the window ca sing with side flanges extending angularly therefrom and provided with a plurality of corrugations affording resilient connection with said intermediate rail portion, a projecting ridge portion on one of said flanges, and a marginal portion on the other of said flanges closely embracing the sides of said ridge portion with an externally disposed edge portion and adapted to hold a screen material between said ridge and said embracing portion.

3. A binding rail for a rolling window Screen formed integrally from a single sheet metal strip shaped to present an intermediate portion for engagement with a window casing with angularly extending flanges at the sides thereof, one of said flanges having its margin curved back upon itself to provide a ridge portion and to engage with said other flange. said other flange having its margin curved to closely embrace said ridge portion with its edge portion extending inwardly of the rail, and being adapted to retain a screen material between said curved margin and said ridge portion, and'a handle on said rail.
