To all whom it may concern:

Be it known that I, WIRT B. BOYCE, a citizen of the United States, residing at the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Roller Shades, of which the following is a specification.

My invention relates to window shades in which the curtains'are mounted on spring rollers. The disadvantages of the ordinary arrangement in which one curtain is used to each window are well known. The window is primarily shaded only at the end to which the shade roller is attached. And the window cannot be opened at the roller end without causing drafts which quickly injure and destroy the curtain. It is de- .vide means by which a plurality of rollers may be mounted midway of the top and bottom of the casing, by which the window may be completely shaded if desired, both at the sides and at the point where the rollers are in juxtaposition, and by which the shades being movable toward the top and bottom of thewindow respectively,

' permit any'op'ening'of the sash either from the top or bottom as desired, without-the currents of air passing therethrough and striking the curtains.

The principles of my invention. are illustrated in the drawings, in which- Figure 1 is an elevation of my improved window shading device, looked at'from the inside; Fig. 2 is asection of the same on the line 2-2 of Fig. 1;

Fig. 3 is a detail perspective of a combi- ,nation bracket; and

Fig. 4 is a perspective of one end of my light shield. Further describing my invention with reference to the drawings, 1 represents the vertical sides; 2 the top, and 3- the sill of a window casing. Within the casing are two guillotine sashes, the upper one having .the rails 4 and 5 and stiles 6 and 7, and the lower one having the rails 8 and 9 and the stiles 10 and 11. At a point on the inside of the vertical portions of the window casing opposite where the rails 5 and 8 overlap I mount a plurality of curtains on spring rollers. The upper curtain 12 is wound on the roller 13, and by means of cords 14: and 15, which'pass over rollers 14-. and. 15 and are connected to the single cord 16 may be adjusted at any desired height. =In like manner a lower roller 17 is mounted below the one last described',.and by means of a cord 18 may be adjusted as desired. The spring rollers should be mounted so as to take 'up or unroll in opposite. directions, thereby placing the curtains on both in practically the same vertical plane. There is necessarily a certain space left between the rollers to give free action even when the curtains are wound on them. This space is increased as the curtains are unwound. To cover this space and make a complete curtaining of the window, when it is desired to shade the same, I provide a light shield, shown in Fig. 4. It may consist of a strip of shade cloth folded at 20, and having rows of stitching 21, spaced from each other so as to produce an elongated loop from end to end, within which may be inserted a strengthening strip 22. The same should be placed in the rearof the rollers so as to cover the variable space between them.

' While separate mountings may be provided for the rollers and for the light shield, I prefer to assemble them in one bracket, as shown in Fig. 3. This may consist of a plate 25, having a socket 26, adapted to provide a bearing for the stub shaft at one end of an ordinary shade roller, and a squared retainer 27 to take the squared or flattened end of the? spring shaft. It will be seen that the'brackets should be made in pairs, the bracket corresponding to the one shown being provided with the shade.

retaining means in reversed relation. At a point centrally in the rear of the roller attachments should be placed a slotted receptacle 30 to receive the ends of the strength ening strip 22. It will further be noted that the brackets constructed as shown provide means by which the several parts of the device, including the rollers and the light shield therefor, are placed in proper relative position to each other without special fitting or measurement when being installed.

Having thus fully described my invention what I claim and desire to secure by Letters Patent is- I 1. In combination with a window shademounting plate having a support thereon provided with parallel spaced walls, of a light shield consistin of a strip of fabric longitudinally folds and having a plurality of rows of stitching spaced from each other and from the edges of said strip to form an elongated loop from end to end of said strip, and a rectangular strengthening rod in said loop having the ends thereof projecting beyond the ends of said strip for reception in said supports whereby the light shield is held in a substantially rigid position.

2. A device of the class described com prising a mounting plate, a plurality of shade roller sockets carried thereby, a U-shaped support carried by saidplate, at a point between the shade roller supports and having spaced parallel walls and a light shield supported at its ends in said U-shaped support and cooperating therewith to prevent relative rotary movement of the mounting plate and light shield.

In witness whereof, I have hereunto subscribed my name this 27th day of October 1915, in the witnesses.
