WALTER J. COX, OF WIOHITA, KANSAS.

SPECIFICATION forming part of Letters PatentNo. 282,277, dated July 31,1883.

i Application filed March 14, 1883. (N model.)

To aZZ whom it may concern:

Be it known that I, WALTER J. Cox, a citizen of the United States of America, residing at Wichita, in the, county of Sedgwick and State of Kansas, have invented certain new anduseful Improvements in Window-Shades, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in window-curtains, having mainly. for its object top or raising it from the bottom, or doing both, to admit air or sunlight at either of saidpoints; and it consists of means "for carrying out this object, substantially as hereinafter more fully set forth or otherwise.

In the accompanying drawings, Figures 1 and 2 are views in front elevation of my improvement as applied to a window, the cornices or coverings of the rolls and their pulleys being removed in one view. Fig. 3 is an enlarged detailed view, showing a broken-away roll and its pulley; and Fig. 4 is a similar end view of the pulley end of the roll.

In carrying out my invention I employ two curtain-rolls, AA, arranged transversely, and about at the middle of the window, the-same being supported in brackets a a, fastened to the window-facings. At points near the four corners of andto the window-frame are hung pulleys B B. O O are conoidal-shapedpulleys I applied to opposite ends of the curtain-rolls,

as seen in Fig. 1.. These pulleys are preferably connected or fastened to the curtain-rolls by short metallic shafts or rods 11, which have cranks formed therewith, as shown at b, for the operation of the rolls. spirally grooved upon their peripheries, as at c, Fig. 3, while at their inner ends they are provided with polygonal or angular proj ections or shoulders d, Fig. 4, against which bear.

flat springs D, screwed or fastened to the window-facing. These springs are designed, in connection with' shoulders (I, to prevent the curtains from running downfrom force of grav ity when the cords become loosened.

E E are the curtain-cords, there being'two V to each curtain, and their arrangement in connection with each curtain being the same.

These pulleys are Oo'rm'ces E are connected to thewindow-facing, so as to cover the curtain-rolls and all the pulleys, imparting to the window a highly ornamental appearance, as observed in Fig. 2. to enable the lowering of thecurtain from the The springs D, bearing upon the projections d of the pulleys O, serve to hold the rolls so as to retain the curtain at any desired point of elevation.

It will be noticed that as any one of the curta'in-cords is acted or exerted upon in the required direction the curtain will be raised or lowered, and that whenthe lower curtain is lowered the slack cord will be taken up by the spirality of the groove, as will be also the case with the'slack cord of the upper curtaincord when that curtain is raised. This arrangement will enable the letting of light and air, or only light without air, into the room, when such is desired, either from the top or bottom of the window, or at both points.

Haying thus describedmy invention, what I claim as new, and desire to secure by Letters Patent, is

1. Awindow-curtain adapted to be raised from the bottom or lowered from the top by means of its cords wound in spiral grooves in conoidal pulleys and actuated byacrank, sub stantially as shown and described.

2. The combination of pulleys B, conoidal pulleys O, secured to curtain-roll A, crank 12, and curtain-cords E, substantially as shown, and for the purpose described.

3. The combination of the.curtain-roll A, having octagonal projections or shoulders d,

and springs D, substantiallyas shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

WALTER J. 00X.
