To all ohom it may concern:
Be it known that I, HENRY HoLoRoET, of Media, in the county of Delaware and State of Pennsylvania, have invented certain Improvements in Curtain-Gord Retainers, of which the following is a speciication:
My invention consists of a coiled spring with two curved projecting arms, the coil being at the intersection of the arms. The arms are connected by a sliding cross-bar, in which is formed an eye for the cord.
Figure l is an elevation, showing the ordinary flxtures for a curtain, with my improved cord-retainer. Fig. 2 is an end view of the same.
Similar letters in the drawings refer to like parts.
B is the roller, on which the shade or curtain is wound. On the right-is a grooved pulley. Each. end of the roller is supported by brackets b b. D is the cord. Fis the cordretainer, and is constructed of spring-wire in the following manner: An eye is formed of two ormore coils, and the ends c a are curved up in the form'of the letter V with the tops turned over, as shown in the drawing. his
the cross-piece, which is also made of Wire, and is formed with an eye in the center, anda small one at each end, through which passes the ends a a.
My improvement is applied in the following manner: The cord D is passed over the pulley 'on the roller, and then through the eye in the cross-piece h. It is then drawn tight till the cross-piece h is about two-thirds up the arms a. a, when an oval-head wood-screw is put through the eye formed by the coils and screwed into the window-casing E. The coiled spring and curves in the arms a. a will draw down the cross-piece h and keep the cord tight through all changes of temperature and atmosphere, and will retain the curtain in any position it may be placed.
In a curtain-cord retainer, as described, the combination, with` a coiled spring provided with curved arms a c,of the sliding cross-piece h, as and for the purpose specified.
