CHARLES W. RODECKER, OF CHARLESTON, WEST VIRGINIA, ASSIGNOR 0F ONE-THIRD TO JACK P. IVIQNEILL AND ONE-THIRD TO JAMES W. HOLLADAY, BOTH OF CHARLES- WINDOW-SCREEN.

Applieation filed February 6, 1914, Serial Ire 817,016. Renewed June 9, 1915. Serial No. 83,198.

To all 7.071171% it may concern Be it known that 1, CHARLES "W. Ronncnnn, a citizen of the United States, residing at Charleston, in the county of Kanawha and State of West Virginia, have invented a new and useful WVindow-Screen, of which the following is a specification.

This invention relates to window screens of that type in which the screen fabric is adapted to be wound upon a spring roller and one of the objects of the invention is to provide a screen of this type having its roller adjustable longitudinally so as to be used in connection with a screen fabric of any desired width.

A further object is to provide an exten sible housing for use in connection with the roller, said housing being adapted to be secured within the window frame or casing and being adjustable so as to fit tightly against the sides thereof, the extension or shortening of the casing resulting in a corresponding adjustment of the roller contained within the casing.

A further object is to provide a roller which will extend automatically when the stantly in engagement with the end walls of the casing.

Another object is to provide a screen the casing of which can be readily placed in position within a window frame or casing and which can be easily removed whenever desired.

A further object is to provide a screen the fabric of which has means whereby it can bedetachably connected to a window sash so that, when the sash is moved out of its normal position, the screen fabric will be unwound from its roller.

\Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination .and arrangement ofparts and in the details of construction hereinafter described and claimed, it being understood that changes in' the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings, the preferred form of the inventionhasbcen shown.

In said drawingsz -l igure l is a front elevation of a window having screens, such as constitute the present invention, comand thus remain con- .its inner end is open.

bined therewith. Fig. 2 is a central vertithe roller being shown therein partly in section and partly in elevation. Fig. at is a vertical transverse section through the screen and its housing. Fig. 5 is aperspective view of the housin Fig. 6 is a perspective view of the roller. Fig. 7 is a per- I spective view of a portion of a guide strip adapted to be used in connectionwith the screen.

Referring to the figures by characters of reference 1 designates a window frame or casing having upper and lower sashes 2 and 3 slidably mounted therein as ordinarily. Any suitable means, shown generally at 4, may be provided for locking either of the sashes against movement in one direction. This means constitutes no part of the present-invention but has been disclosed in a copending application filed by me. A screen is adapted to be usedin connection with each sash, the two screens being duplicates. Each of these screens includes a casing such as shown in detail in Fig. 5. This casing is made up of an elongated boxlike member 5 one end of which is open while its otherend is closed. as indicated at 6, there being inwardly directed guide flanges 7 formed along the longitudinal edges of the section 5. Another elongated boxlike section 8 is slidably mounted within the section 5 and is retained therein by the flanges 7 which. lap the longitudinal edges of the section 8, the outer end of said section being closed, as indicated at 9 while The two sections thus cooperate to form a longitudinally adjustable-casing. The section 8 has'a longitudinal slot 10 in one wall thereof and into which extends a clamping screw 11, the head 12 of the screw bearing upon the inner face of said wall while the threaded portion of the screw, which projects through and be ond the adjacent wall of the section 5, carries a clamping nut 13 or the like. Thus it will be seen that by tightening the nut upon the screw the two sections can be clamped together after being adjusted to any desired positions relative to each other. Slot 1.0 is preferably so located that it will at no time be exposed outside of the casing during the adjustment of said casin Specification of Letters Patent. Patented July 2%, 1915..

The end wallti of the casing has a slot 14; adadted to receive the an 'ular trunnion 15 of a roller 16, said trunnion projecting into the .rollerand forming part of a stem 17. A coiled spring 18 is secured at one end to the stem and at its other end to the roller so that, when the said roller is rotated, in one direction, the spring 18 will be woundtightly about the stem and, when roller 16 is'released, the spring will operate to; return it to itsinitial position. Theother end wall9 of the casing has an opening 19 to receive a cylindrical trunnion 20 extending from a tubular extension 21 carried by the roller 16. This extension telescopes into one end of the roller and a spring 22'is housed within the roller and extension and serves to press said extension normally outwardly. A slot 23 is formed longitudinaily within extension 21 and :1 lug 24 is struck inwardly from the roller 16so as to project into the slot and thus limit the. outward movement of the extension.

The screen. fabric, such as shown at 25, is cutito a width equal to the width ofthe window opening and 18. secured at one end to the roller 16. and its extension. This fab-.

the lower sash 3, the nut 13 is loosened and the housing or c asing, with roller ,16 therein, is placed on the sill of the Window and then elongated so to bring the end Walls 6 and 9 firmly in engagement with the sides of the Window casing. During this extension of the housing, the roller 16 will be automatically extended by spring 22 so as to maintain its trunnions 1 5 and '20 Within the openings 14 and 19 respectively. After the casing hasbeen thus positioned, .the nut 15% is tightened so as to clamp the two sections 5 and'8 together. The free end of the screen fabric 25 is then'attached to the lower rail of sash 3 by placing the loop or ring 27 in engagement with. a hook or button 28 extending from the middle of the lower rail.

It will be apparent therefore that when. the

sash :5v is raised, the screen fabric will be unwound from. the roller'16, this operation causing the spring 18 to gradually wind The screen fabric will When' the sash is lowered, the spring 18 causes the roller .16 to rotate and automatically the slack in the screen fabric.

take up tion of the upper rail of the upper sash. In addition, guide strips, such as shown in ,Fig. 7, may be secured along the partingstrips. Each of these guide strips is prefcrably formed of light sheet metal and includes an attaching or base strip 29. and .an

outstanding guide strip 30, said guide strip or flange lying close to the path of the sash 2, thus forming a .channel in whichtlfe edge portion of the screen fabric is adapted to work. An arm 31 maybe extended inwardly from the upperend of each guide strip so as to constitute a supporting bracket on which the upper casing may be mounted, as indicated in Fig. 2. The side edgesof the screen connected to the lower sasharepreferably guided by head or guide strips 32 secured along the sides-6f the Windosgv1 frame or casing close tothe path ofthe sas As shown particularly in Fig. 2, a flexi ble-guard strip 33 may be attached to the bottom of the lower rail of the upper sash 2 so as to contact. with the outer-face of the lower sash 3 and thus prevent, flies from passing between the lower sash and the lower rail of the upper sash.

VVhat' is claimed is A windo-w screen including telescopically connected casing sections each having its outer end closed and provided with one open face, the ends of the sections being pressed inwardly and provided with trunnion receiving openings, a roller having trunnions extending therefrom and into the openings, said roller being made up of sections, a spring for controlling the rotation of the roller, a springhoused Within the roller and between the sections for holding the trunnions seated within the openings at all times during the extension and contraction of the'casing, said inwardly pressed portions constituting thrust bearings for the roller, and means for securing the easing sections together to'prevent automatic extension of the roller and casing.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of-two Witnesses.
