weaves.

To all whom it may concern Be it known that 1, DAVID ONEILL, a citizen of the United States, residing at lVdside, in the county of Queens and State of New York, have invented certain new and I useful Improvements in Rolling Window- Screens; and I do hereby declare the following to be a full, clear, and exact descripopening and closing of a window so that the space caused by the window being inan open positionwill be closed by the screen and when the window is in a closed position, the screen is rolled up and protected.

' from the weather and other foreign matter.

xAnother object of this invention is to i provide a casing secured-to a window frame andhaving a spring rewound roller therein which 1s connected to a window sash for 1;; closing or cleaning a window when the sash is moved in an open position, thus preventing insects and the like from passing through the window.

A further object of this invention is to end of the screen to the window sash for causing the screen to move upwardly and downwardly with the sash and which is adapted to close the opening in the casing WlllCh permits the screen to enter and exit therefrom when the sash is in a closed position, thus preventing rain and other foreign matter entering the casing.

A further object of this invention is to end of the casing for receiving and guiding the edges of the screen and wh1ch has means thereon for clamping them and the casing tothe window frame so that the casing and jguide members 'Inav be readily detached from the window framewhen desired.

A still further object of this invention is the provision of a rolling window screen of the above stated character, which shall. be simple, durable and eflicient, and which may be manufactured and sold at a comparatively low cost.

lVith these and. other objects in view as it will become more apparent as the descrip- .tion proceeds, the invention consists in ear Patented Sept. 18, 1917.

Application filed November 28, 1916. Serial No. 133,865.

tain novel features of construction, combination and arrangement of parts as Will be. hereinafter more fully described and claimed. a

For-a complete understanding of my invention, reference is, to be had to the following description andaccompanying drawings, in which:

Flgure 1 is a front elevation of a window illustrating a rolling window screen applied thereto and which is constructed in accordancewith my invention,

Fig. 2 is a vertical sectional view of the same,

Fig. 3 is a fragmentary vertical sectional vlew illustrating the means of connecting the guide strips to the casing,

Fig. at is a longitudinal sectional view of the casing illustrating a spring rewound roller therein,

Fig. 5 is a fragmentary elevation partly in section of the casing illustrating the opening and one of the guide strips for the screen,

Fig. 6 is a detail sectional view taken on the line 6-6 of Fig. 4E,

Fig. 7 is a detail elevation of a modified form of securing the guide strips to a window frame.

Referring in detail to the drawings, the numeral 1 indicates a window frame having the usual sill 2 and the vertical guide ways 3 and a in which are slidably mounted the upper and lower window sashes 5 and 6. The foregoing description relates to a well known construction of a window and to which my invention is applied. My invention may be readily applied to either the upper or lower window sashes 5 and 6, but to better illustrate the same I have elect ed toshow my invention attached to the lower .windov'v sash 6.

"An elongated casing 7 is provided with a curved top wall 8 which is slotted adjacent the'rear wall thereof asillustrated at 9 for forming an exit or opening to the casing. The casing 7 has its ends closed by end walls 10 which are each apertured for the purpose of rotatablv supporting a roller 11, which will behereinafter more fully described.

A pair of vertically extending guide strips 12 rest on each end of the casing 7 adjacent the s1ot 9 for receiving the edges of a screen 13 which is wound upon the roller 11 within the casing and extends out arms into an engagement with one of the walls of the guide way, 3 will force the guide strips against the other wall, thus locking the guide strips within the guide way 3 and simultaneously holding the casing 7 upon the window sill 2.

The roller 11 has inserted in the ends thereof cylindrical blocks 17 and18. The

cylindrical block 17 is provided with a circular bore for receiving a pintle 19 that extends through one of the end walls 10 of the casing for rotatably supporting the roller 11. The cylindrical block 18 has a circular bore to receive a pintle 20 which is rotatably mounted in the opening of the other end wall 10 of the casing and has a squared bore 21 for receiving a key for rotating the block 18 within the roller 11. The block 17 is secured to the roller 11 by a screw 22 or like fastener. Each of the blocks 17 and 18 have inwardly directed reduced extensions 23 formed thereon for receiving the ends of a coil spring 24.. The ends of the coil spring 24 are secured to the blocks 17 and 18 as illustrated at 25. By rotating a key (not shown) after being positioned within the squared bore 21 of the pintle 20 the block 18 will be rotated thus winding up the spring 24 within the roller so as to cause the roller 11 to wind the screen 13 thereon when released or allowed to move in the direction of the casing 7. The

block 18 is provided with an aperture for receiving a pin 26 which is adapted to extend through an aperture in one of the end walls 10 of the casing 7 for locking the block 18 against rotation in the roller 11 after the spring 24: has been wound.

An attaching strip 27 is provided with a longitudinal groove for receiving the free end of the screen 13 and which is secured within the groove by means of pins or like fasteners 28. Downwardly depending tongues 29 are formed on the attaching strip 27 and engage the window sash and are held thereon by substantially U-shaped clamps 30, thus it will be seen when the window sash is moved upwardly and downwardly the window screen 13 is compelled to travel therewith within the guide strips 12. l/Vhen the window sash is moved in the direction ofa closed position, the screen 13 moves downwardly or winds upon the roller 11 within the casing 7 under the influence -V of the spring 24, so that the'screen is ontirely incased or inclosed when the window sash is in a closed position.

From the foregoing description taken in connection with the accompanying drawings it will be noted that a screen has been provided which may be readily attached or applied to a window frame and windowsash without the use of nails or like fasteners, thus obviating the danger of marring or injuring the wood work of the window frame. It will also be noted that whenever the window sash is moved'to an open position so as to allow ventilation of the room, the opening within the window is immediately or automatically closed by the screen 13 and innnediately upon downward movement of the windowsash to a closed position, the screen 13 iswound upon the roller 11 within the casing 7 thus entirely protecting the samefrom foreign matter-when in non-use. It'will also be noted that this device may be readily detached from a window frame and sash by removing the clamps 30 freeing the attaching strip 27 fromthe window sash and turning the locking arms 15 upon their pivots so that the gulde strips may be detached fromthe guide ways of the window frame, the casing 7 is then free to be lifted from the window sill 2 and stored in a comparatively small space.

Formedupon the attachingstrip 27 isan extension 31 which is adapted to overlie the opening 9 of the casing 7 when the window sash is in closed position, thus preventing rain and other foreign matter from entering the casing which would causethe screen 13 to be become rusted or injured so as to render it of non-use. The flanges 14: of the guide strips 12 have their lower ends bent at right angles andrest on the casing 7 while the rear wall of the guide strips extend downwardly in rear of the casing, whereby the guide strips are substantially secured to the casing when in operation.

Referring to my modified form of fastening means forthe guide strips to the Window frame as illustrated in Fig. 7, it con-V sists of an internally screwthreaded boxing lVhile-I have shown and described the preferred embodiment of my invention, it

will be understood that minor changes in construction, combination and arrangement of parts may be made without. departing from the spirit and scope of the invention as, claimed. I

Having thus described my invention, What I claim is:

1. A rolling Window screen comprising a casing, a spring roller journaled in said casing, a screen Wound on said roller and extending exteriorly of the casing, an attaching strip having a groove to receive the free end of the screen, means for securing the screen Within the groove, downwardly depending tongues formed on the attaching strip, and substantially U-shaped clamps securing the tongues to a Window sash.
