THEODORE B. MILLER, OF RICHMOND, INDIANA.

ROLLER WINDOW-SCREEN.

Specification of Letters Patent.

Patented June 26, 1917.

Application filed June 2, 1916. Serial No. 101,393.

To all whom it may concern.-

Be it known that I, THEODORE B. a citizen of the United States, residing in the city of Richmond, in the county of Wayne and State of Indiana, have invented a/new and useful Construction for Roller Window-Screens, of which the following is a full, clear, and comprehensive specification, being such as Wlll enable others to make and use the same with exactitude.

The object of my present invention,

broadly speaking, is to provide a roller window-screen which will be neat andattractive in appearance, strong and durable in construction, easily operated and controlled, highly efficient in practice, and

which can be manufactured, sold, and installedat a comparatively low price.

More particularly stated, my object is to provide a window screen which when once installed need not be removed, being adapted to roll up out of theway when so desired, and as easily and quickly brought to operative position when required; and having means whereby the screen is at all times under tension, by which it will not sag or bulge causing it 'to'become inoperative or unsightly.

Other minor objects and particular ad vantages of the invention will suggest'themselves in the course of the following description and that which is new will be correlated in the appended claims.

One manner for constructing, arranging, and of carrying out my invention in a practical and mechanical manner is shown in the accompanying drawings, in which Figure 1 shows my invention in elevation in connection with a window, and in closed operative position. Fig. 2 is a vertical section of the parts shown in Fig. 1, except that the screen is shown as only partly closed. Fig. 3 is a longitudinal vertical section, taken centrallythrough the roller, showing the screen entirely open, that is wound upon the roller, and showing two springs in the construction. Fig. 4: is a longitudinal vertical section taken through the roller, the screen being omitted, and showing the construction with, but one spring. Fig. 5 is a plan viewof one of the springs alone. Fig. 6 is an enlarged detail of one of the bearings. showing a portion of the roller in position in connection therewith.

Extending Fig.7 is a horizontal cross section as taken through one of the vertical guides, as on the line 7-7 of Fig. 2. And Fig. 8 is an end view of the springs.

Similar indices denote like parts throughout the several views. In order that the construction, the advantages, and the operation of my invention may be fully understood and appreciated I will now take up a detailed description thereof in which I will set forth the invention as briefly and as comprehensively as I may.

In the drawings letters A and B denote the two sides or jambs of a window frame. C denotes the sill and D denotes the lintel. It will be understood that the window frame may be fitted with the usual sash or sashes, and that it may be of any desired form, the particular style or shape shown being simply for convenience of description, but the invention is not to be limited thereto.

The invention proper comprises the two end plates, 1 and 2, which are adapted to be secured to the opposing faces of the re spective jambs A and B, by nails or screws.

Permanently connecting the plates 1 and 2, and extending th'erebetween, is the hood or container 5, which is tubular in shape, but with a longitudinal slot extending from end to end thereof, which slot opens downward and to one side, as indicated at w in Fig. 2, to form the mouth. One lip of the mouth extends down vertically a short distance, as indicated at vin Fig. 2.

Secured to and projecting inward from.

the respective plates 1 and 2 are the tubular bearings 6 and 7, which are concentric with the hood 5, and project thereinto a short distance.

Numeral 8 denotes the tubular roller which extends across with its ends fitting either around orwithin the said bearings, on which bearing the roller is adapted to revolve, as hereinafter set forth.

Located in the end portions of the roller 8, parallel therewith, are the

helical springs

9 and 10. The end portions of said springs are doubled back diametrically across the ends of the springs to form slotted eyes a at each end of each spring, the termini being secured by twists around the end of the last coil at each end of each spring, as shown in Fig.

through the roller 8, and

through the inner eye of the springs are the respective pins 11 and 12, by which the springs are connected to the roller 8.

Likewise extending across through each of the bearings, 6 and 7, are the respective outer pins 13 and 14 which pass through the outer slots in the eye terminals of the

respective springs

9 and 10, by which the outer ends of the springs are connected to the bearings and are, therefore, stationary with relation to the inner ends of the springs, which latter revolve with the roller.

Numeral 15 denotes a wire screen, whose width is slightly less than the distance between the jambs A and B, and whose length is such as to cover the interior space of the window frame. The upper edge of the screen is secured along on the periphery of the roller and parallel therewith.

Secured to the lower edge of the screen is the angle-strip 16, whose base is adapted to contact with the sill C, and whose length is substantially the same as the width of the screen.

Secured to the respective jambs A and B are the guides 17 and 18, each comprising a single length of sheet metal having a base portion adapted to be secured to the jambs by screws or nails, from which base portion the metal extends inward and is reversed outwardly with the two portions in contact with each other, and then projecting outward and spaced from the double portion to form the channels, as indicated at f in Fig. 7, in which channels may operate the end of the strip 16 and the edges of the screen, as shown.

Formed horizontally through the end portions of the strip 16 are small apertures which register with like aperatures 12 formed through the projecting flanges of the guides, to receive the removable pins 19 and 20 by which the screen may be secured either in closed position or at various points in partly open position as desired.

Extending out and upward from .the angle strip 16, and located near the guides 17 and 18, are the

hooks

21 and 22, which are adapted to engage with the lower edge of the lip a when the screen is rolled up, thereby not only limiting the upward movement of the screen but also centering the screen in its movement in the guideways 17 and 18.

From the above it Will be noted that the entire mechanism may be assembled in operative position, except the guides, before being secured in the window, the only labor required being to insert the device in place and secure the plates 1 and 2 and the guides 17 and 18 to the window jambs, it of course being understood that it has been prepared to exactly fitbetween the jambs.

When the device is being assembled the springs are placed under proper tension, such as to normally retain the screen wound Fig. 4, while for other end of the screen, means upon the roller to its limit. After being placed in position it is apparent that one may grasp the base portion of the anglestrip 16 and by pulling down the screen will unroll, the roller revolving against the tension of the spring or springs, and when brought down, as in Fig. 1, the pins 19 and 20 can be inserted, which will retain the screen in closed position as shown.

In connection with ordinary or small windows only one spring will be required, this being placed at one end of the roller, as in larger windows it is best that two springs be employed, as indicated in Fig. 3. Also the length of the springs will depend somewhat on the length of the screen in connection therewith.

Screens thus arranged need not be removed during the months they are not required, but they may be simply released, by removing the pins 19 and 20, and allowed to roll up out of the way where they will be protected and be in readiness when again required.

I desire that it be understood that various changes may be made in the several details of construction herein set forth without departing from the spirit of my invention and without sacrificing any of the advantages thereof.

Having now fully shown and described my invention, what I claim and desire to secure by Letters Patent of the United States, 1S-

1. A roller window screen comprising end plates attached to the window jambs. bearings projecting toward each other from said plates, a roller mounted in connection with said bearings, a screen having one end attachedto the roller and adapted to be wound therearound, a metal strip secured to the for automatically causing the screen to be wound upon the roller, a hood surrounding the roller and the screen, there being a downwardly opening slot through said hood for the screen to operate through, hooks carried by said strip and adapted to engage one of the lips of said slot. and guide-ways secured to the window jambs and extending downward in alinement with said slot.

A roller window screen adapted to roll upward and to be unrolled when the free strip secured along the free end oi the screen, hooks carried by said strip for securing said strip upon the window sill; a. hood surrounding the roller and adapted to inclose the screen when the screen is wound upon the roller, there being a downwardly opening slot in the hood for the screen to operate through and through which slot the said hooks can not pass, guide-ways secured to the window jambs and extending downwardly from said slot to the Window sill with the edges of the screen adapted to operate in said guide-Ways, all substantially as shown and described.

In testimony whereof I have hereunto 15 subscribed my name in the presence of two subscribing witnesses.

THEODORE B. MILLER.
