EXTENS lON- SCREEN.

srfnozsioazrron forming part of Letters Patent No. 689,769, dated December 24, 1901. Application filed October i, 1901. Serial No. "77,582. (No model.) 7

To all whom, it incty concern.

Be it known that I, HARRY A. \VAY, of Burlington, in the county of Ohittenden and State of Vermont, have invented a new and useful Improvementin Extension-Screens, of which the following is a specification.

My invention relates to that species of extension screen or blind in which the stiles are combined with tongued lateral extensionstrips which enter grooves in the stiles and are spring-pressed in an outward direction.

My invention consists in certain structural improvements in thisspecies of screen,which will first 'be described in connection with. the" accompanying drawings, forming part of this specification, andwill thcn'be more particularly pointed out in the claims.

In the drawings, Figure 1 represents in front elevation my improved screen fitted in place ina window-casing. Fig. 2 is an enlarged perspective view of-a portion of the screen with parts broken away to expose the interior structural details.

A indicates the top and bottom rails, an B the stiles, of the screen-frame.

0 indicates the extension-strips. w

The particular screen shown in the drawings is one designed to slip up and down like a window-sash, and for this purpose the extension-strips Ghave grooves in their outer edges, which fit guide rails or strips (1 on the Window-casing. Of course if the screen is not to slide the, grooves 0 can be dispensed with. 'The screen-stiles are grooved in their outer'e d-ges, as'at b, and the extension-strips C are'tongued, as shown, to enter and fit the grooves, in which they are capable of movement outwardly and inwardly, so as to'extend' or contractthe screen, as thecase may be,

The extension -strips are spring pressed outwardly. This'of course, broadly considered, is old; but I believe the construction and arrangement of parts for this purposeshown in the drawings to be new with me. The strips are outwardly spring-pressed at each of theirjends, and the springs for this purpose are h'ousedinthe top and bottom rails. The springs are coiled springs s, and each is contained in a socket 25, formed for,in, and longitudinally of the top or bottom rail A, as the case may be. This arrangement permitsof the use of long springs, giving ample room for expansion and contraction'without impairing their efficiency, besides which the springs are entirely contained and concealed within the rails and are effectually protected from the weather.

For the purpose of holding, guiding, and strengthening the extension-strips G each of them is provided near each end with a rod D, which is-secured to the inner edge of the exso as to screw into the extension-strip, and,

its inner end is bent at right anglestoits shank, as seen at d, this bent end when the extension-stripis in its extreme outward position bringing up against a cross-pinfidriven into the rail A, so as to pass crosswise through tension-strip and projects inwardly therefrom Preferably the outer the sockett at a point which will prevent the tongue of the extension-strip froin'passing out beyond the groove 1) in the stile. After the rods D are screwed into the extensionstrips they are inserted bent end foremost into the sockets t, which already contain the springs s, and then the cross-pinsare driven into the rails crosswise of the sockets between the extension-strips and the bent ends dot the rods attached to said strips and at points to prevent, as before said, the tongues of the extension-strips from passing out beyond their grooves 12 in the stiles.

- As a'convenient means of retracting the extension-strips G, I make use of rods E, one of which is secured to each strip C at about its middle and thence extends loosely in- ,wardly through thestile B, its inwardly-protruding end being provided with a ring Her other convenient handle by which it may be manipulated. By drawing inwardly upon these rods E the screen can be contracted to permit its ready removal from or application to the window-casing.

What I-claim as new and of my own invention is--.

1.In an extension screen or blind of the class specified, a screen-frame having stiles provided with grooves in their exterior opposite edges, and extension-strips provided with tongues which fit and are movable in said grooves, in combination with coiled springs contained and housed in sockets formed in and longitudinally of the top and bottom rails,

' rods attached to said extension-strips and exs housed in said sockets,,rails D secured to said extension-strips and extending into said sockets and provided with bent ends d, hearing plugs or seats interposed between the rods and springs against which said rods bear, and pinsf, inserted in the top and bottom rails and extending through and crosswise of the sockets therein to engage the bent ends d, as and for the purposes set forth.

In testimony whereof I have hereunto set my hand this 26th day of September, 1901.
