L The'Sehednle referred to in these Letters Patent and making par): of the Sallie.

`invented an Improved Mode'vof Hanging Window- Shades; and I do hereby` declare the following descriptionand accompanying drawings'are. sufficient to enable any person skilled in the art Vor science to which-it most nearly appertains, to make and use in y said invention and improvements `without further invention or experiment.

The nature or! essence of my invention consists in` al eertainarrangement o f cords, rollers, pulleys, and weights, hereinafter t'ullyset forth, whereby a cnrtain may be rolled n p `from the bottom, and rolled down from ,the top,land either end supported at any desired height.

To more fully illustrate and explain my invention,

reference is had to the accompanying drawings, form-y 'inga pait'of this specification, of which- Figure 1 isk a front View of a window with aishade l attached; i

Similar letters of reference in each of' the gures indicate like parts.

A is the frame of a window.

The curtain, or` shade, B, is` attached, at each end, toa roller, G, of the proper length`to allow the cur- -tain tocover the 'entire window.

The rollersare made somewhat longer than the width oi' the shade, and have Iformed 4on theirends grooves, a a, whichserve as'pulleys.

To-hang the curtain in ii'ont of the window, take strong cords, b,and secure them at the lower corners of the window.

These cords pass up, and a turn is taken with them i around the pulley on the ends of' the' lower roller, and then up`around the pulleyson the ends of the upper roller, in a `similar manner. Y

The cordmay then pass up through staples, c c, at the upper kcorners of the window, and be united togethe'r across the top, by means of an elastic or other spring, d; `or'thecords may pass over pulleys behind the casing; and be held bya Weight. Or a still more 4simple device would be to attach `the cord to some suitable device, fixed at the upper corners of the casing, and allow it to hang vertically, passing around therollers, as above described, and through a hole in the lower sill of the window, and vattaching the weight to the lower end, the object of the arrangement being to take up'the slack of the cords, and keep them continually taut.`

These cords are used as guides for the rollers, and to produce Athe necessary friction to cause them to turn when the proper raising-device is applied.

`On the ends of the rollers O are gudgeons, 'i i, around which a link, g, isv placed loosely, so as to allow the gudgeo'ns to turn inV their lower ends.

To this llink is attacheda cord, a, which 'passes to the upper corner of the window, on the side on `which A weighted` tassel, I, is then placed-on it, byruni ning the cord through an eye, placed in any favorable position, forming a bight, by carrying the cord up and again-through the staple `p,and attaching the end to the link g, onthe opposite end of the lower roller.

The tassel I is weighted suciently to balance the weight of the roller, and the roller is heavy enough to descend, when the weight of thetassel is relieved.

The cord which controls the upper roller is attached and arranged in the same` manner as the lower one, the bight being formed andthe` tassel hangingon the opposite side of the window from thelower one.

When tlie'weighted tassel which retains the upper roller in place is raised upward, the roller, by its own weight, will descend, rolling the curtain ,as it moves,

the vfriction occasioned by the peculiar arrangement of the Ycord around the pulley causing it to roll as it moves up or down; andwhen the tassel is released it will balance the weight of the roller, and keep it stationary; and when it is desired toraise or close thegudgeon from coming in contact withV the side-casing ofthe window, as-it moves. up and down. The ylower rollernis operated in the same manner,

only it rolls lthe curtain around it as itascend's, andi-,"

unrolls it when it descends. v A poition of the cords may be concealed, when de sired, behind the casing, so as to hide them from.

sight.

By this means, I have a window-shade, or curtain,

which mayeither be rolled up from the bottom, or downfrorn the top,las desired, the'operation of raising and lowering being quitesimple, and easily performed by achild; and,fshould it be desired to leave the window open, either at the top or the bottom, for the purpose of admitting freshjair into the room, the .wind cannot disturb the curtain, as it is held irmly to its place by the guide-cords.

Having thus described my invention,

What I claim,and desire to secure by .Letters Patent, is

The combination and arrangement of the cords b, y

a, and it', the tension-spring d, and the rollers C, when applied to both ends 'of a curtain, so that the top may be rolled down, and the bottom rolled up, and each sustained -at any desired height, by means of the weights I I', substantially as described.

In witness whereof, I have fhereunto set myhand and seal. A
