' IMPROVEMENT IN WINDOW-CURTAIN FIXTURES.

To all 'whom 'it may conce/rn.-

Beit known that I, THOMAS CHARLES WILLIAMS,

of East Randolph, in the county of Dodge and State of Wisconsin, have invented a new and useful Improvement in WYindow-Curtain Fixtures; and I do hereby declare that the follo'wing is a full, clear, and exact description thereof, which will enable others skilled inthe art to make and use the same, reference being had to the accompanying drawing forming part of this specifica-tion.

Myv invention relates to window-curtain xt'ures, and consists in a peculiar arrangement of the cords and balance-weight with respect to the curtain-roller and top slat.

In the accompanying drawingv Figure 1 represents a front View of a curtain or shade suspended from a window according to my invention.

Figure 2 is an edge view ofthe same.

Similar letters of reference indicate corresponding parts.

A is the window.

B, the curtain or shade.-

C C are two cords, by which the curtain is suspended.

D is the weight by which the curtain is balanced,

which weight may be in the form of atassel or in any other form.

Eis a slat, to which the top of the curtain is attached. l c' F is the roller, to which the lower end of the curtain is attached.

The cords C G- are attached to the slat hl behind the curtain, as seenat G G, (in dotted lines.) From these poiuts'the cords are brought down underthe The Schedule referred to In these Letters P atent and making part of the name.

roller F and up in front ofl thecurtain, and passed through the screw-eyes H H in the slat F; from thence down and through the eyes I I. on the weight D, and then up to the slat, where they are fastened at the point J.

As the weight vD is designed to just. balance the` ciu'tain or shade, with the aid of the friction of the cord'through the screw-eyes, it will be seen that as the weight is raised the curtain will be lowered, or the A4curtain will be raised or rolled up by pulling down the weight,and that the curtain will beheld in any desired position by the weight.

By this arrangement the curtain may be attached tothe upper sash of the window so that it will drop with the sash and not interfere with ventilation, as curtains do when attached in the usual manner to the casing.' v

Pulleys instead 'of screw-eyesmay be used, but they would materially increase the expense of tle fixture without improving it.

. This is a cheap and durable mode` for operating win? Witnesses:
