WINDOW-SCREEN.

Liaoning ments in window screens, preferably of the f adjustable type, having a relatively Wide range of adjustment to fit windowscf differentwidths between the sash and top or Ybottom of the vframe for Ventilating purposes, and also to exclude insects, dust and other floating matter.

VThernain object is to provide a screen roll mounted in one end of the frame,- and capa' ble of being extended across frames of differentlengths, and attached to the opposite endthereof in such-manner that it may be yeasily and quickl released, and rewound upon the roller w en desired, thus perrnittingxthe same screen to be used with rigid or'adjustable frames.

.Another object is to rovide Athe adjacent edges of the lower an upper rails of the frame Awith lengthwise f channels 'for receiving and guiding the adjacent edges of the screen, and' holding said screen in a, flat plane. 1

A further object is to provide adjustable connections between the frame sections4 for holding said sections in any position'of adjustment to closely lit between the sides of the Window frame, and at the same time,

permitting the sections to be retracted when.

removin or replacing the iframe.

A stil -further object is to construct the adjustable connections in such manner that f Y they may be used as a `means for positively retracting and extending the frame sections.

Other objects and uses relating to specific parts of the screen and its supporting trarne Will be brought out in the following description.

F ig. 7 is an en arged detail sectional View through a portion orp one of the length# wise Arails, showing more particularly-the manner of fastening the cross barthereto. Fig. 8 is an enlarged detailsectional'view of the screen attaching means taken on line 8 8, F ig. 2. p .i

This screen isused. primarily for ventilating purposes, and consists of a rectangular frame composed of lJ-shape sections 1 and 2 having respectively, upright parallel end bars 3 and 4-, the frame section- 1 being provided with lower and upper parallel rails 5 rigidly secured at one end tothe upright bar e while vthe y section 2- isrovided with lower and upper parallel rails f3- rigidly secured at one 'end to the upright bar The

rails

5 and 6 are spaced sub stantially uniform distances apart and. are slidably interlocked with each other to pern mit the frame sections to be extended 'or retracted to fit between the upright casings of windows of dierent widths between the sash and lower or upper portion of the Window frame, as may be desired. These'rail

sections

5 and 6 are preferably made ot' sheet metal, tubular in form, so as to fit one withinthe other, except that their inner lengthwise edges' are provided with substantially' fla-t flanges 7 which are spaced a slight distance apart to,folrm relal tively narrow vertical channels 8 '`or ren cciving and guiding the opposite lengthwise edges of a screen fabric 9 as the latter is drawn across the frame in a manner hereina ttor described.

The main bodies of the rails 5 and arc substantially rectangular in cross brought closer together at or near the .longitudinal centers of the main bodies to form the central lengthwise channels -8-, and at the same time, materially stifenin the rails, it being understood that the shou ders, as -10- formed by drawing the flange portions J7- closer together, serve-t0 lock the telescoping portionsY of the rails against relative lateral or vertical movement, or

rather to hold them in alinement, thereby maintaining all portions of the frame in a substantially flat vertical plane.

The screen +9- is preferably made of light cotton cloth or equivalent material, of such dimensions as to cover the entire opening in the frame when the latter isextended to the limit of its adjustment with its longitudinal edges entering the channels -8- and one end attached to a roller -'-li the opposite end being secured to a light but comparatively stiff reinforcing bar -12-,' which, together with the roller -11-, serves to hold the fabric in a substantially flat plane against buckling, wrinkling' or folding, the bar -12- being of approximately the same length as the verl'tical width of the fabric and is suiliciently spring -l6- is secured, the opposite end of said spring being attached to the roller -11-. .i

The outer end of the rod or stem -17-- is preferably angular in cross section, as shown more vclearly in Fig. 4, and is engaged in an open-sided slot -'-18- of a bracket 19- on the corresponding end of the upper rail v-5- so as to hold the stem against turning, the slot being preferably open at the top toA 'inserted therein or removed when desired,

' and is provided near its lower end with a.

lateral enlargement forming a 'shoulder --20-- with which the angular portion of the rod or stern is'normally interlocked to prevent accidental displacement thereof,

particularly when the screen is retracted' upon the roller.

The intermediate portions of the lower andupper rails, and particularly the inner ends of the rails -5- of the section -l-, are connected by cross bars -21- havingtheir ends rigidly secured to the adjacent portions of the rails by. any suitable fasten ing means, as tongues which it struck up from the opposite walls of the channels S5- and are forced into recesses -23 in opposite edges of the cross bar to firmly lock the latter against outward or. .lateralv movement relatively to the frame seclion -1-.' One of these cross bar s also constitutes a convenient support for theop- 'erating means by which the frame sections may be extended or retracted, l said operatingmeans comprising in this instance a cran arm -24- pivoted at one end at 25J-to one of the cross bars -21- and its other end provided with-.a handle v--26- by A clamping block Q7- nected-to the crank arm --24- land provided with a lengthwise opening for receiving a rod or bar -Qlfwhich is pivotally connectedat -29- to the end bar -4-, as shown'more clearly in Figs. land 2. This connecting rod or bar --28* is adjustable endwise in the apertured clamping block -27, the latter being provided with a set screw 3G- by which the rod maybe firmly clamped` to the block -27- to hold the frame sections -3- and v lim in their relatively adjusted positions.

may be rotated about the pivot4 is pivotally .coni The crank-arm -24-- and connecting rod i 28- constitute what may be termed a toggle connection between the frame sections -l and -2-, 'and also constitute a toggle lock for lholding said sections in their extended positions, by reason of the fact that the pivotal ,connection between the crank-arm 2lb-4 andv clamping member -27- assume a position in a substantially straight line between the pivots 25# and` 22%d with the free end of the rod -28` resting on the hub ofthe 'crank-arm M24- as shown in'Iigs. 1 and 2. When it is desired to contract the frame lengthwise, it is simply necessary to swingthe crank-arm 24- upwardly to the position indicated by dotted lines in Fig. thereby reducing the length of the frame as an entirety and permitting it to be withdrawn from the window, or in a reverse manner replaced in the window. l

The lower and upper brackets -14- and l-19- at opposite ends of the roller -11- are connected by a cylindrical section -31- forming with said brackets and the end bar 3- of the frame a suitable housing`for and screen wound thereon.

lll

'The operation of my invention will now be readily understood with reference to the` foregoing description, taken in connection with the drawings, and it is evident that all elements thereof may be substituted by equivalents without de arting from the spirit of this invention. herefore, I do not limit myself to the precise structure show n and described.

What I claim is:

1. A window screen,comprising two frame sections, slidable one upon the other, an up-` right roller housing on one end of one section, a roller.in said housing, and a screen having one end attached to the roller to wind thereon, and' its other end movable across the frame and provided with means for attaching it to the opposite side of said frame, spring means for automatically retracting the roller to tension the screen in j any relative position of the frame sections.

2. A Window screen, comprising a frame, having lengthwise channels in adjacent edges of opposite sides thereof, a roller housingI on one end of the frame, an upright roller j lurnaled in said housing, ascreen at tached at one end to the roller, and movable across the frame and having its opposite edges guided in said channels, the opposite end ot' the screen being provided with means for attaching it to the corresponding end of the frame.

3. A window screen, comprising two frame sections slidable one upon the other, a cross bar connecting opposite sides of one of the sections, adjustable connections between said cross bar and the end of the other section, and a screen stretched across the openings in both frame sections."

4. A window screen, comprising two frame sections slidable endwise one upon the other,

a roller housing on one end of one of the sections, a roller journaled in said housing, a screen attached at one end to the roller, and having its other end provided frame sections, a crank-arm journaled on the cross bar, and connections between said crankearm and the other frame section for moving the last named section as the crankarm is rotated.

6. A window screen comprising two 'frame sections slidable endwise one upon the other, and means for extending and retracting said sections, said means being adjustable'to varyV the degree of extension.

7. A window screen comprising frame sections adjustable endwise one upon the other, a crank-arm journaled on one of the sections, a rod pivoted to the other section, sliding connections between the crank-arm and rod, and means for clamping the sliding connections against relative sliding movement.

In witness whereof I have hereunto set my hand this 15 day of October 1914.
