MOLDING FOR SCREENS.

Application filed February 17, 1914. Serial No. 819,196.

To all whom it may concern;

Be it known that I, EDMUND L. SMITH, a citizen of the United States, residing at San Francisco, in the county of San F rancisco and State of California, have invented a new and useful Molding for Screens, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a metal molding through which the edge of a window screen slides. 7

It will be understood by those skilled in the art that where roller screens are used that a slide for the edges of the screen must be provided to hold the screen edges to prevent the'ingress of insects, and such a slide must be of such a character as not to unduly wear the screen material, while, at the same time, it holds the screen securely in the desired position in the window.

An embodiment of the invention is shown in the drawing in which the same reference numeral is applied to the same portion throughout, but I am aware that there are many modifications thereof.-

Figure l is a front elevation of a Window and screen therefor having this moldingapplied to the edges of the window frame, for the purpose of holding the screen, Fig. 2 is a side elevation of a portion of the window frame slide, and Fig. 3 is a horizontal sectional view of the slide.

The numeral 1 represents the window frame, 2 the lower sash and 3 the upper sash. At the upper end of the sash the screen curtain roller 4 is installed in the well known brackets 5 and 6. The screen is wide enough so that the edges overlap the edges of the window frame and extend into the metal slides 7, and 8.

Each metal slide is made from a strip of fiat metal 9 which is bent back upon itself at 10 to provide the space through Which the holes 11 can be made to secure the slide in place and the other portion of the edges Specification of Letters Patent.

of the slide are bent to stand a short dis tance from each other as indicated at 12 and 13, and each of said edges is in turn bent inwardly as indicated at 1 1 and 15 to provide a smooth surface against which the screen contacts. The metal used is of a suitable stiffness to cause the parts 14 and 15 to bear tightly against the screen material and thus hold it firmly in place.

It will be observed that the fabric 17 is provided with a number of stiflening rods 18, each of which rods has a small knob 19 and 20 to I ing pulled out of place. These knobs are not great enough in number to interfere with the the roller, but are sufficient in number to prevent the screen from being pulled out of the slides 7 and 8.

Having thus described my invention what claim as new and desire to secure by Letters Patent of the United States, is as fol- I lows, modifications within the scope of the claim being expressly reserved:

A roller screen comprising a screen roller, a screen thereon, a rods extending transversely across the screen, each rod having a knob at each end thereof, and a metal guide molding at each side of the window frame for holding the screen. said molding comprising a sheet of metal having itsedges inturned and adapted to bear upon the screen and having one portion thereof bent into contact with another portion thereof, while a further portion is spaced from the back of the molding a sufiicient distance to pass through.

prevent the screen fabric from be-' proper winding of the screen upon.

permit the screen knobs to plurality of stiffening In testimony whereof I have hereunto set my hand this 11th day of February A. D. 1914, in the witnesses.
