ROLLING WINDOW-SCREEN.

SPECIFICATION forming part ofV Letters Patent No. 267,618, dated November 14, 1882. Application tiled September 22, 1882. (No model.)

To all fr0/tom it may concern:

Be it known that I, THOMAS TRIBE, a citizen of the United States, residing at Colorado Springs, in the county of El Paso and Stateot' Colorado, have invented a new and useful Rolling Window-Screen, of which the following is a specification, reference being had to the accompanying drawings.

Figure l is a perspective View Ot' a windowframe having my improved screen and shade, part having` been broken away in order to show the construction more clearly. Fig. 2 is a vertical sectional View. Fig. 3 is a` horizon- 'ta-l sectional view on the linex, Fig. 2. Fig. 4 is a horizontal sectional view 011 the lineyy, Fig. 2. Fig. 5` is a front view, parts having been broken away. Fig. 6 is a vertical svetional view illustrating a modification in the arrangement of the screen. Fig. 7 is a detail view ofthe lower end'of the screen; and Fig. Sis a detail View of the lower end of the shade.

Corresponding parts in the several figures are denoted by like letters of reference.

This invent ion relates to rolling screens and shades for windows; and it consists in certain im provcments in the construction and arrangement of thetsame, which will 'be hereinafter fully described, and `particularly pointed out in the claims.

` In the drawings hereto annexed, A represents an ordinary window-frame, B the upper and C the lower sash.`

The screen I), to which my invention principally relates, is made of any suitable netting, and is attached to and adapted to be wound upon au ordinary spring-roller, E, inthe construction ot' which no novelty is claimed. If

. the window-frame to which my invention is appplied has no inside blinds, l arrange the brackets or bearings F for said roller, as shown in Fig. 6, directly infront of the inner sashbead; but when, on account of the use of inside blinds, this is not practicable, I secure at the upper end of thewindow-frame, between the inner and middle beads, blocks G, ilushwithsaid beads, to which the roller-brackets Fare then secured. These blocks, whichneed not exceed 'a'few inches in length, do not materially interfere with the operation of the lower. or inner sash, the weight-cords of which are accommodated in grooves H inthe inner.

lare thereby kept stretched and taut.

rectly above the screen-roller E, as shown in the drawings.

To the sidesof the window-frame or oi" the inner beads, K, as the case maybe,are secured vertical guide-strips L, having recesses or pockets M and narrow slits N, to receive and guide the edges of the screen and shade,which In order to retain them in the pockets M, and to prevent their sliding out through slit N, the said screen and shade are provided with cords O, parallel to and at a short distance from the edges, said "cords being threaded through the fabric, as clearly shown in Figs. 7 and S ofthe posite sides. I would have it understood that `this construction is an important feature ot' my in ventiou, and is essentially different from an ordinary bound or corded edge, formed by inclosing a cord in a hem of the fabric. Such construction would prevent the fabric from winding smoothly and perfectly upon the roller, and render the device practically inoperative and valueless, while by my improvement a perfect and successful operation is insured. It will be noticed that thepockets M are amplylarge to accommodate any surplus edge of the fabric outside the cord O.

The sides of the window-frame (or the inner beads) just below thescreenrollerare connected by a pair ot' transverse guide-strips, l) Q, between which the shade passes. The outer strip, Q, is connected with the top of the window-frame by a boxing, It, of wire-netting or other suitable material,thus making a tight joint, which absolutely prevents the admission of insects at this point.

The screen D has at its lower edgea Slat, S,

of such lengthA as to fit nicely between the edges of the screen, their upper ends being se- `IOO W W are elasticstrips arranged near the.

cured to the roller E and theirlower ends to slat S. These strips have several important functions-namely, to assist in holding the fabric of the screen stretched and taut to brace it against the wind or other pressureand to space it as it is being wound upon the roller, thus adording room between the layers for the cords O, thus depriving the latter ot' any tendency to cause the screen to wind uneven'ly. Being elastic, the strips W rwill stretch in the 4act of windin g, thus packing the screen fabric nicely and closely upon the roller.

The shade I is, like the screen, provided at its lower edge with a slat, X, havinglaterallyprojecting guide-plates Y. Elastic strips may also be used in connection with the shade; but I do not deem it essential.

The screen-strip S is provided at both ends with suitably -constructed spring bolts or catches Z, projecting so as to engage notches A at various points in the guide strips or rails L. The inner ends of the bolts Z are connected bya cord, B,which is guided through snitably-located screw-eyes C', so as to form a central pendent loop, D', by means of which the screen may be adjusted and manipulated. Thus by pulling the loop D the bolts or catches are released from the notches. By continuing to pull the screen may be lowered to the desired point, while by raising the hand the screen will be wound upon the roller. This catch or bolt mechanism is an important feature of my invention, as by it the screen-Slat S may be adjusted closely in contact with the window-sill, and may be readily raised or lowered by simply manipulating the cord-loop D.

When my improved window-screen is used separate from the shade I substitute guidestrips L having a single pocket and slit, M'N.`

In other respects the construction will be the Same.

My invention, aswill be seen, is applicable screens. All of this I do not claim; but

I claim and desire to secure by Letters Patent of the United States- 1. A rolling screen or shade having cords threaded through the fabric of which it is conlposed, near the edges, substantially as setforth.

2. The combination, with a rolling screen, of elastic strips arranged near its edges, and attached to the roller and bottom slat, substantially as set forth. y

3. The combination, with a rolling screen or shade having cords threaded through the fabric ot' which it is composed, near the edges, of elastic strips arranged near said cords, and having their upper and lower ends attached to the roller and bottom slat, respectively,.as set forth..

4. The combination of the window-frame,the spring-roller E, the screen D, having cords 0 threaded through its fabric near the edges, and the guidestrips L, having pockets M and slits` N, as set forth.

5. The combination of the spring-roller, the

rolling screen, the transverse guide-strips P Q, and the Wirenetting box R, as and for the purpose set forth. 6. The combination, with the window-frame, of the blocks G, having grooves H, the bearings or brackets F, and the screen-roller, substantially as set forth.

7. The combination ofthe 'rolling screen, the cords threaded longitudinally through the same, and the bottom slat having laterallyprojecting plates to which the lower ends of said cords are secured, as set forth.
