WINDOW-SHADE BRACKET.

Application filed August 12, 1921.. Serial No. 491,721. I

To aZZ whom it may concern:

Be it known that I, EDWARD S. SMITH, a citizen of the United States, and a resident of Anderson, county of. Madison, and State of Indiana, have invented a certain new and useful lVindow-Shade Bracket; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts. 7

This invention relates to a window shade bracket wherein the window shade may be moved back and forth, against and away from the window in order to clear the ventilator sections of some windows and is of the same general type illustrated in Patent No; 704,894. a

The main feature of the invention lies in the mechanism for moving the entire window shade, to and from the window, Whereby it may either lie adjacent the window when so desired, or be spaced therefrom when necessary because of the extended posi tion taken by certain types of windows and ventilators. This is accomplished by mounting the shade roller upon a traveling crane construction in turn supported at each end 011 horizontally and outwardly extending tracks for permitting the positioning and spacing thereof from the window casing.

The full nature of this invention will be understood from the accompanying drawings and the following description and claims.

Fig. 1 is a front elevation of a window casing with a movable window shade mounted thereon, parts being broken away. Fig. 2 is a side elevation of the supporting bracket with the movable window shade mounted thereon, taken on a line 22 of Fig. 1. Fig. 3 is a side elevation of a portion of the supporting bracket having the outer end thereof broken away, taken on the line 3-3 of Fig. 1. Fig. 4 is a perspective view showing the development of the guide cords. Fig. 5 is an enlarged side elevation, with parts broken away, of the supporting bracket and traveling block. Fig. 6 is an enlarged plan view looking down on the supporting bracket and traveling block. Fig. 7 is an enlarged front elevation of a portion of the supporting bracket and traveling block.

In the drawings there is shown a window casing 10 upon which is mounted a window shade 11 of the usual type, which is suspended from the shade roll 11. The shade 11 and the shade roll 11 are of the usual type commonly used, and instead of being supported in the usual fixed brackets to the window casing, the roll is supported in a traveling block comprised of side plates 12 having a recess for securing the supporting ends 13 of the roll 11. The side plates 12 are supported upon the flanged wheels 14 which are mounted upon the track 15 so as to freely roll thereon. The track 15 is rig-' idly secured to a bracket 16 which is firmly fixed upon each side of the window to the casing 10. Said bracket extends laterally and forwardly from the window and is supported at its outer endby the brace 17 which is secured at its outer end to the track and at the other end to the bracket 16. By means of this arrangement the carrying block and the window shade may be moved forwardly on the track away from the window or rearwardly thereon to adjacent the window.

For maintaining the traveling blocksmounted on each side of the window parallel with each other in their movements, there is provided an endless cord 18 which passes about the forward pulleys 19 mounted on the spindles 20 at the forward ends of the sup orting track, and about the rear side pul eys 21 pivotally supported on the brackets 16 by the ears 22. -The' right. hand traveling block is secured to the upper strand of the cord 18 by means of the engaging plates 23 and the set screw 24, so that the right hand block travels in the direction taken by the upper right hand strand. The left hand traveling block is secured in the same manner to the lower strand of the cord 18, as shown in Fig. 3. As the upper right hand strand and the lower left hand strand of said cord move in the same direction with the same rate of movement, said cord will maintain both driving blocks in o the tube 26 in which the plates 23 and screw 24 are mounted and through which the cord 18 passes. By means of the arm 25 the cord 18 is spaced from the traveling blocks and is rigidly connected to each of said blocks for imparting the same relative movement thereto. The traveling blocks and shade may be moved back and forth to and from the window by any suitable means, such as a cord and pulley, or by a window stick as may be desired.

The invention claimed is:

1. The combination with a window casing and a shade therefor, of means for supporting said shade adjacent said window casing, comprising laterally extending tracks, traveling blocks mounted thereon torsupporting said window shade, and a single band which said traveling blocks are secured for maintaining them'at an equal distance from said window casing and said shade parallel there? with in moving said shade on said track to and from said window.

2. In a window shade support of the character described, the combination with a gaging and maintaining said cord in paral- I lel relation to said track and retaining said block upon said track.

' 3. In a window shade support of the character described, the combination with a supporting track, and an actuating cord in spaced relation therewith, of a shade sup porting block, comprising a plurality of rollers engageable upon said support, a spaced framework for straddling said track and securing said rollers, and an outrigger construction extending axially of said rollers and outwardly from said framework "for engagement with said cord and maintaining said framework upon said track.

In witness whereof, I have hereunto fixed my signature.

EDWARD S. SMITH.
