WINDOW-SHADE.

.FIQATION forming part of Letters Patent No. 340,981, dated May 4-, 1886.

Application filed September 11,1885. Serial No. 176,798. (No model.)

To atZZ whom it may concern.

Be it known that I, \VALTER J. COX, of \Vichita, in the county of Sedgwick and State of Kansas, havcinvented certain new and use ful Improvements in IVindow Shades, of which the following is a full, clear, and exact description.

This invention relates to certain new'and useful improvements in window shades, in which a shade is used for the upper part of the window and another shade for the lower part,whc'reby the shades can be adjusted more easily, less space is required for the shades, and no light can pass in between the shades.

The invent-ion consists in the construction and combination of parts and details, as will be fully set forth and described hereinafter.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a front view of a window provided with my improved window'shades, parts being broken out. Fig. 2 is a cross-sectional elevation of the same on the line a: av, Fig. 1.

Two bracket-pieces, A, are secured on the windowirame B one at each sideand are united at the top by a cross-piece, B. In the lower part of the brackctpieces A two shaderollers, D and E, are journaled, the roller D being above the roller E and slightly behind the same.

The bracket-pieces A are each provided near their lower ends with u pwardly-curved notches A for receiving the end pivots of the lower roller, E, the pivots being held in placeby the tension of the cord, as will be described hereinafter. Said roller E can be removed after the cords have been detached.

A window-shade, F, is secured on the roller D, and a shade, G, is secured on the roller E.

The roller D is provided on one end with a grooved pulley, I-I, outside of the bracket piece, and on said roller a cord, J is wound, which is passed through eyes K I on the edge of one bracket-piece A, then extends downward and has a weight, L, secured on its end, which weight balances the shade F, which hangs down from the back of the upper roller, D, and down behind the lower roller, E.

To the shadeG on the roller E a cord, M,

is secured on each corner, and the said cords are passed through apertures N in the upper parts of the bracket-pieces, then extend downward on the outer sides of the bracket-pieces, and have their lower ends secured to COllOldlll grooved rollers P on the ends ofthe roller E.

To lower the shade F, the end of the cordJ is lifted, thus permitting the shade to unwind from its roller D under the action of the weight of said shade. To raise the shade F, the weighted end of the cord Jispulled down, whereby the roller is revolved in such amanner as to wind the shade on said roller.

If desired, the shade F can be pulled down by means of a tassel, loop, or cord secured to the bottom of said shade, and the upper roller, D, on which the lower shade is secured, may be a spring-roller.

To raise the upper shade, G, the outer part of either cord M is pulled down, to cause the inner parts of the cords M to pull the shade up. As the shade is unwound from theroller E, the cords M are wound on the pulleys P.

To lower the upper shade the outer part of either cord M is moved upward, whereby the roller E is revolved in such a manner as to wind the shade on said roller E.

I am aware that two eurtainshavebeen used to a window, each adapted to be wound on a roller arranged at about the middle of the window, and provided with colloidal-shaped rollers, upon which the cords attached to the curtains are adapted to be wound, and I therefore do not claim such invention.

Having thus described myinvention,what I claim as new, and desire to secure by Letters Patent, is

1. The combinatiou,with two bracketpieces at the sides of the window, of two shade-rollers jourualed in the same, one roller being slightly above the other, and the upper roller being slightly back of the lower roller, of a shade secured to the lower roller and extending upward in front of the upper roller and a shade secured to the upper roller and hanging down behind the lower roller. substantially as herein shown and described.

2. The eombination,with two bracket-pieces, A, having notches A", of the roller E, having its pivots passed into the notches, the roller D, journaled in said bracket-pieces above and slightly behind the roller E, and shades Se of the roller D, passed through eyes on one bracket-piece, and a weight on the lower end of the cord J, substantially as herein shown and described.

\VALTER J. COX.
