ROLLER WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent N 0. 618,823, dated February '7, 1899.

Application filed \Tune 9, 1896 Renewed June 18, 1898. Serial No. 683,868. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS E. BARR, a citizen of the United States, residing at the city of Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented a certain new and useful Roller Window-Screen, of which the following is a specification.

My invention relates to improvements in roller window-screens.

It relates more particularly to roller window-screens which occupy a space outside the sash and independent therefrom.

The objects of my invention are, first, to provide a construction specially adapted for the position which it is intended to occupy; second, to provide a convenient and simple means for absolutely clamping the edges of the screen to retain them in place; third, to

' provide improved means of locking the screen in the closed position; fourth, to provideimproved means of operating the screen to carry it evenly and truly to place, and other objectsappearing in the detailed description. I accomplish these objects of my invention by the means and mechanism described in the following specification and illustrated in the accompanying drawings, in which Figure 1 is an outside elevation of a window with one of my screens in position, portions of the same being broken away to show details of construction. Fig. 2 is a vertical sectional view through the same on lines 2 2 of Fig. 1. Fig. 3 is an enlarged detail sectional view on line 3 3 of Fig. 2, looking down. Fig. 4 is an enlarged detail View of a part of the clamping means, showing the method of operating the same. Fig. 5 is, an enlarged detail perspective view of the means of securing the screen in the closed position. Fig. 6 is. a sectional view on line 6 6 of Fig. 5. Fig. 7 is a sectional View on line 7 7 of Fig. 5. Fig. 8 is an enlarged detail view of a portion of the roller, the end being cut in section. Fig. 9 is an outside elevation of a Window with portions broken away to show the details of construction of the means of actuating the window-screen. Fig. 10 is a sectional view on line 10 10 of Fig. 9 through the same. Fig. 11 is an enlarged detail sectional View on line 11 11 of Fig. 10. Fig. 12 is an enlarged detail sectional view on line 12 12 of Fig. 10. Fig. 13 is an enlarged detail View of a modification on a line corresponding to line 3 3 of Fig. 2. enlarged detail view of the modification corresponding to view in Fig. 4.

In the drawings all of the sectional views are taken looking in the direction of the little arrows at the ends of the section-lines, and similar letters of reference refer to similar parts throughout the several views.

Referring to the lettered parts of the drawings, A is the shaft supporting the roller F in the upper part of the window-casing.

B is the window-screen or wire net, which is carried by the roller and extends down from the top of the blind-stop or along the blind-stop.

At each side of the window-frame is a strip of molding G, placed upon the inner edge of the outer casing parallel with the blind-stop. At the inside of the strip 0 is a clampingstrip E, which is supported by suitable screws f through the oblique longitudinal slots f.

therein. A knob f is provided on this piece for moving the same,and by crowdingit down, owing to the action of the screws f the strip is clamped securely against the screen B and strip 0, which of course clamps the edge and holds it very securely. On the free end of the screen, as here constructed, I secure a suitable binding made up of a strip of wood or other suitable material a on one side and the strip or on the other, which are held together by suitable fastenings which clamp them to the edge of the screen securely. The strip a is notched on its end and engages the strip 0, which guides it and the screen. On the under side of the strip a is secured a thin strip of spring metal g,which projects slightly below the strip a. and serves as a yielding means to close up all irregular openings that might be formed below the lower edge of the screen over the window-sill. Little staples or loops cl are inserted in or secured to the window-sill and project up into little recesses in the binding of the free end of the screen. Opposite these loops and pivoted to the screen by suitable screws are hooks c, the upper edges of which are broadened and flattened and turned out to form suitable lifts or handles for manipulating the screen and for operatin g the hooks themselves. Theengaging part of these hooks is made comparatively Fig. 14 is an long and eccentric to the point of pivoting, so that when they are engaged in the loops d by crowding upon them they clamp the binding very tightly in position. Under ordinary circumstances and for windows of ordinary height this is all that will be required to make the screen completely and satisfactorily 0perative.

\Vhen the windows are very high or very broad, or, for that matter, when for any reason it becomes desirable or it becomes necessary to operate the screen with great accuracy, I provide the special means for operating it definitely shown in Figs. 9 and 12, inclusive. Beneath the window-sill I insert a drum I on a spindle or shaft I, which receives its main support from the hanger J. On this shaft is a gear-wheel It. On the inside of the lower casing is a spindle t, carrying a larger gearwheel 2', which meshes with the gear h. A hand-wheelj is on the outer end of the spindle t" and serves, through its gear connections, as a means for actuating the drum I. On each side of the window-frame and within the window-casing are supported suitable guide pulleys or sheaves t t. A cord 0 r is connected to each side of the screen at the binding and extends along the strips O,around the guide-pulleys i, and passes to the drum I at the center. Here they wind onto the drum in opposite directions, which consequently draws the screen to position perfectly straight. WVhen the drum is operated from the handwheel, a ratchet on the hand-wheel j enables the same to be locked at any point without making use of any other means, although it is much more secure if the hooks o are used in addition.

In Figs. 10, 13, and 14 is shown a slight modification of the clamping means for the edge of the screen. An additional yieldingly-supported strip 0 is placed on the blind stop and is clamped against the strip 0 by clamping-strip E. A piece of rubber e is inserted in the edge of the strip 0. The clamping-strip E does not need to extend the entire length when this style is adopted to se cure a full clamping.

Having thus described my improved roller window-screen, it will be clear from the description that it is capable of considerable variation in the details without departing from my invention. The screen will be quite effective without the strip d at the bottom of the binding-strip. Other means could be provided that would clamp the binding to the window-casing, though the means that I have illustrated is very simple and very effective and possesses merits over any other. The same could be said of the clamps for forcing the strips at the edge together.

As I have intimated in the description, special means for pulling the screen into position could be dispensed with under many circumstances. Other variations will suggest themselves to those skilled in the art'to which my invention pertains.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a window-screen apparatus, the combination of a roller above; a screen attached thereto; strips 0, rigidly secured to the outer casing bearing on their inner edges the strips e, strips 0, yieldingly supported upon the blind-stop; clamping-strips E, with oblique slits f therein; and screws f, passing through the oblique slits into the blind-stop to afford a means for clamping the edge of the window-screen securely in place as specified.
