Application led. May 21,

To all whom t may concern:

Be it known that I, WILLIAM BLANCHARD, a citizen of the ignited States, residing 'at Boston, in the county of Suffolk and State of Massachusetts, have invented. new and useful improvements in Window Shades, of which the following is a specification.

This invention relates to improvements in shade fixtures particularly adapted for use with windows having swinging sash.

in object of the invention is to provide a lixture mounting a shade for movement 'toward or away from the window so that when the sash are swung open the shade may be moved away from the window a suliicient distance to clear the sash whenit is lowered.

Another object of the invention is to provide a movable mounting for a shade roller with means for guiding the free end of the shade and means for moving the shade toward or away from a window.

Other objects reside in the details of construction and cooperation of the parts which are clearly pointed out in the following de scription and claims and shown in the accompanying drawings in which,

Figure l is a sectional view through a window using swinging sash with the shade iixture shown in cooperation therewith and the shade drawn,

lligure 2 is a detail elevation of the shade fixture constructed according to this invention,

Figure 3 is a detail elevation at right angles to Figure 2 showing the shade lixture and shade in position, and

Figure l is a detail view of the bracket for guiding the operating cables.

A window sash is generally indicated at 1- having swinging sections -2- mounted on horizontal pivots as clearly shown in Figure l.

Ainclined track bars 3- are secured to the ceiling adjacent the window frame through terminal extensions -aN and movably re-` ceive shade roller carrying members 5- Qrovided with rollers 5w riding on the track bars. The members 5- have depending roller holders -7- pivotally mounted thereto at -8- and detachably receiving the shaft -9- of the shade roller through the clamp connection -1()-. Guide members -1l have one end secured to the clamping portions 10 of the roller holders and the other ends passed through eye 1923.L seran no. `crease.

bolts -12--v mounted below the window and if secured toy spring members '-,-13- fastened to the floor as indicated aty -14-- This resilient lconnection ofk the guide members` .permitsy the free movement fofk the roller holding members on the track bars.v

window as indicated iii/'dotted line at 15-'; in Figure 2 due to track bars. c, Operating cables .l6- are connected with ythe roller holding members -5- and guided over pulleys -l7- and 1S- mounted on bracket -l9- removably se? cured to the terminal extension Afadjacent'the window frame, the cables terminating in a single operating member dependingV to the lower end of the window where it may be connected with any suitable operating means generally indicated at 21- whichwill draw the roller holding members up the inclined track ways to position the shade close to the window which is desirable when the swinging sash are in closed position.

rlhe free edge of the shade -22- is provided with a cross-bar -23- having terminal eyes *24freceiving the guiding members l1 for guiding the shade as it is raised `and lowered and for preventing the same from flapping.

It will be seen from the above that a simple shade hxture is provided for use with swinm ing sash to permit thedrawing of the shac e when the sash are opened vwithout interfering with said sash and which will hold the shade in any desired position with relation to the window and which may be operated to draw the shade into close proximity with the window when the sash are closed.

The terminal portions of the shaft 9 of the shade roller are each provided with a pair of spaced circumferential disks 25 between which the free end of tape 26 is attached for raising the shade; The lowering ofthe shade causes the tape to wind on the shaft 9 between the disks 25. it is only necessary to unwind the tape, the shade being maintained in elevated position by tying or hooking the tape to some portion of the window or wall structure, which has not been illustrated.

l/Vhile the invention has been disclosed in concrete form,yet various changes and modifications may be made therein without de- To raise the shade The( natural tendency ofthe roller'holdingv members is to assume a'position away from the ,65 ythe linclination of the parting romthe spirit of my invention, the scope of which is dened by the following claims.

What is claimed is:

1. The combination with a pair of inclined tracks having upwardly directed terminal portions adapted for attaching the tracks to a ceiling, carriages mounted on said inclined tracks, holders pivotally suspended from saidcarriages, a roller having pintles connected to said holders, flexible elements connected to said holders and adapted for securing the holders in an adjusted position, guide rods connected to said holders, contractile springs connected to the lower ends of the guide rods, and a shade connected to said .rollers `and having eyelets receiving saidguide rods. Y

2. 'lhe combination with a pair of inclined nected to said holders, flexible elements connected to said holders and adapted for securing the holders yin an adjusted position, guide rods connected to said holders, contractile springs connected to the lower ends oi' the guide rods, a shade connected to said rollers and having eyelets receiving said guide rods, and lengths or' tape connected to said'rollers adjacent the ends thereof and forming a means whereby to adjust said shade.

In testimony whereof I affix my signature.

lILLIAM BLANCHARD.
