' WINDOW-SCREEN.

' Application filed. March 21,

To all whom it may concern: Be it known that -I, MATTHEW CASSON, a citizen-of the United States of America, and residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements inllindow- Screens, of which the following is a saecification, such as will enable those skille in the art 'to which it appertains to make and use the same.

This invention relates to screens for windows and'the'like and the object thereof is in its movement, when a sash is moved; a further object being to provide such a device' which, when not in use, may be rolled into small compass and not be in the way, although always in position for use a further object being to provide such a. device which may be readily adapted to various size windows and which is readily attached to and removed fromits operative position; a furt-lierobject being .to rovide such a device' which is automatical y rolled up, when a sash is lowered, without the use of springs and the like; ,a further object being to provide means whereby the unequal rolling or uni-oiling, due to increasing or decreasing for'to prevent injury to the screen itself or ject being to provide such a device which is" simple in construction and operation, comparatively'inexpensive and well adapted. to the use for whichit is intended.

My invention is fully described in the following s ecification, of which the accompanying rawings form a part, in which the separate parts thereof are designated b the Fi ure 1 is a face view of a window pro- Fig. 2 is an-enlarged section thereof on the sectional, fragmentar view of a detai of the construction; on .t 1e line 3-'3 of Fig; 4;

Fig. 4 is a similar view. on the line 4-4 of netting thereon, means Fig. 3; and Fig. 5 is a fragmentary view of another detail of the construction.

In the drawings forming a part of this application, I have shown a window, a, having sashes, the lower one a" of which is shown in a raised position, the opening Specification of Letters Intent.

PatentedOct; 1s, 1 90s.

caused thereby being covered bya netting b wound upon aroller 19 having caps 12 and two pins I) at each endthe'reof, said roller bein preferably formed of two members secured together and between which thenetting is firmly held, said netting bein preferably of flexible metal but it may a so be of fabric, if desired. 1

Secured upon each side of the windowframe (1,- adjacent the sash a ,.is a metal strip 0, bent, as shown-in Fig. 4, to form two pockets 0 and c -which serve as runs for an endless sprocket chain or equivalent d pass ing over a roller (l and sprocket wheel d" secured at the top and bottom of the strip 0 as shown in Fig. 2, said sprocket wheel (I being provided with two holes d to-receive the pins 6* inorder to rotate the roller I therewith.

Secured to the chain d. is a bracket 6 ex tending ou-twardlyfrom the pocket 0 and carrying a-tube-e having a rode movable therein and normallyforced inwardly by a spring'cfl said rod 6 at cach'side of the window, carrying the corresponding end of a transverse bar 6 to which the netting b is secured, and it will be seen that by means of the springs e a continual tension is maintained on the netting?) although additional strain thereon will be compensated for by the said springs and thus prevent tearing the said netting. i In practice, I prefer to cover the roller b with a casing f which is made telescopic for "adjustment to various size windows and I also employ some means for attaching the bar a or tubese to the sash a such as a hole It in the said tube hanger for 'enga ement with a pin, screw or nail in the sas or a. catch h shown attached and detached in Fig. 1, hinged to the sash and adapted to be en aged with the tube e or any other suit- .bIe equivalent may be quickly attached and detached to either the sash or netting.

Having. fully described my invention, what I claim as new and desire to secure by Letters Patent, is

- 1. 'A window screen, com rising a roller, a :or insuring the movement of the outer end of said netting in the rotation of said roller comprising end-' less chains, a tube secured to said chains at eachside of said netting, anelastic connection between said tubes and said netting and provided which is a and from cstches on a; lnovable pert said tvindow and adapted to engage said tubes endimove saidnettin "with sai movable part;-

2. A win ow screen, comprising a roller,' a

netting thereon; endless chain's fer 'actua-ting said roller,- guide tollers .for sa d chains, a' tube secured to'ea'ch ofsaidlchains, and an elastic connection between said tubes and said'lnetting- J 31 'Aivindowscreen, cqmprising a; roller a netting thereon endlesschdins for actuating s l $19 h 'gu'i e rollersy-fqr said chains, :1-

tube secured to each of said chains, an elastic connectlon between saldtubes, and sald-nett1n and means for connecting said tubes wit a movabl part of said Window.

In testimony that I claim the foregdi'ng as my invention I have signedmy namein presence of the subscriblng witnesses this 19th day of March 1908.
