UNITED STATES CHARLES EATON, OF NEW'YORK, N. Y.

IMPROVEMENT IN CURTAIN-FIXTURES.

Specification forming part of Letters Patent No. 121,342, dated November 28, 1871.

To all whom it may concern:

Be it known that I, CHARLES EATON, of the city, county, and State of New York, have invented certain Improvements in Window-Shade Fixtures, of which the following is a specification:

The object of this invention is to produce a fixture consisting of a spring-roller operated by a single cord that will roll the shade from the top of the window down to the bottom, and from the bottom up to the top, so that it will shade any portion of the window desired. Its principal peculiarities consistfirst,in its simplicity, there being only one single cord required to operate both the top and bottom; second, the tension of the spring, which keeps the shade taut over the window, prevents all rattling and tearing of the shade by wind when the window is open; third,

the operator can drop the cord at any time or in any place, and the stop pulleys, which are automatic, will catch the cord instantly and retain the shade in position, thereby affording the greatest convenience and prevent the damaging of the shade which might occur if not provided with this particular device.

Figure l, of the accompanying drawing, is a front view illustrating the shade as covering the center of the window. Fig. 2 is an end view of the fixture, showing the operation of the stoppulleys. Fig. 3 is a cross-section of the stop;

pulley. Fig. 4 is a front view of the stop-pulley.

A is the spring-roller, to which the shade is attached. B is a strip of wood, to which the brackets G O are made fast the roller with the shade rolled up is placed into the brackets, the spring end of the roller going in the left-hand bracket, which contains a recess to hold the spring. D is the cord, one end of which is passed over the stop-pulley E at the top of the window and fastened to the strip B; the other end passing under the stop-pulley E at the bottom of the window and fastened to the shade slat. The

stop-pulley is easily understood from the drawing. K is the shell. P is the pulley. G is a device so constructed and pivoted at such an angle as to catch the cord automatically the instant it is let loose by the operator and hold it, as shown by the dotted lines. The motion of the cord is stopped by its breaking upon the pulley in combination with the short curve given it by the device G.

I claim as my invention The combination of the spring-roller A, strip B, brackets O O, stop-pulleys E E, and cord 1), when arranged as described, and for the purposes set forth.

GHARLES EATON.
