Nov. 20, 1934. NE 1,981,319 1 WINDOW SCREEN Filed May 7, 1934 IMVENTOR I i 25 {M71 M :::::;f:::: V I I BY 25 I-26 W i ATTORNEY Patented Nov. 20, 1934 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to sliding window screens, and especially to screens made up of a plurality of slidable members adapted for adjustment so as to be applicable to window easements of any dimensions.

The primary object of the invention is the provision of two or more screen sections arranged for sliding contact and located in parallel planes, in combination with novel means adapted to guide the screen sections during such movement. Other objects of the invention will be made apparent in the following specifications, when considered in connection with the drawing forming a part thereof.

In said drawing:

Fig. 1 is a plan view of the screen assembly showing the two screen sections.

Fig. 2 is an enlarged cross-section through the screen members, taken on the line 22 of Fig. 1.

Fig. 3 is a fragmentary view showing a stiffening bar extending medially across and secured to one of the screen sections.

Fig. 4 is a fragmentary section on the line 4-4 of Fig. 1.

Fig. 5 is a top plan view of a clamping member adapted to be secured to the screen meshes.

Fig. 6 is an end view of the bar shown in Fig. 3 and Fig. '7 is an end view of said clamping member, shown in Fig. 5.

Now referring specifically to the drawing forming a part of this application, in which like reference numerals indicate like parts throughout the several views, 10 and 11 indicate the two slidable screen sections, each section being of course provided with top rails 12 and 13 respectively and bottom rails 14 and 15. As clearly illustrated in Fig. 1, said rails are each provided with a longitudinally-extending, centrally-positioned slot 16. As shown in Fig. 1, a strengthening bar 1'7 is secured near the left side edge of the right side screen section, and a similar bar 18 is applied to the right side edge of the left hand section. The bars 1'7 and 18 are formed of metal, and each bar is folded upon a central line, and the ends of said bars are notches. A clip 23, equipped with a housing 23' and having a body portion 24, and horizontally projecting fingers 25, is provided with a plurality of spur fingers 26, which are extended through the screen meshes and then bent back whereby to provide means for securely retaining the clip 23 in position, one side portion of the clip 23 being extended over the strengthening bar 17, and rigidly clamped in such position.

From the foregoing description of the device, and its method of operation, it will be obvious that, when the screen sections 10 and 11 are relatively moved or adjusted, the anti-friction members 20, located in the grooves or slots, 16, will eliminate any binding or sticking action. It will also be apparent that the provision of the bars 1'7, 18 and 22 will not only lend rigidity to the entire screen assembly, but will greatly facilitate the operation of inserting the screen sections into the window casings.

Modifications of the structures herein described may be suggested to those skilled in the art to which the invention pertains, but it is to be understood that my invention includes all embodiments falling fairly within the scope of the appended claims.

I claim:-

1. A Window screen installation including two relatively slidable screen sections, a centrally disposed bar secured directly to the screen meshes of one section, and anti-friction means located between said sections.

2. A window screen installation including two relatively slidable screen sections, a centrally disposed bar extending horizontally between the side rails of the sections, and provided on its side edges with bendable spurs adapted to extend through the interstices in the screen meshes, and to be turned at an angle whereby to retain said bar in operative position.

3. A window screen installation including two relatively slidable screen sections, a bar extending transversely of one section and secured to the screen meshes by spur clips formed thereon and adapted to be extended through the interstices in the mesh and pressed against the latter, whereby to retain the bar in operative position.

4. A window screen assembly including two relatively slidable screen sections, a bar extending transversely of one section, and provided with means for securing it to the mesh, a rigid rod carried by the top and bottom of each section, a metallic clip secured to said one section and provided with a housing surrounding said bar, and antifriction devices located between said sections.
