CURTAIN- FIXTURE.

E-PECIPICATION forming part of Letters Patent No. 332,907, dated December 22, 1885.

Application filed October 8,1885. Serial No. 179,299. (No model.)

To all whom it may concern.-

Beit known that I, WALLACE O. KELLY, of Hastings, in the county of Barry and State of Michigan, have invented new and useful Improvements in Curtain-Fixtures; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form apart of this specification.

This invention relates to certain new and useful improvements in curtain-fixtures; and the invention consists in the peculiar construc= tion, arrangement, and combinations of the various parts, all as more fully hereinafter set forth.

Figure 1 is an elevation of my improved device as hung up ready for use. Fig. 2 is a longitudinal section through the spool end. Fig. 3 is an end view of the same with adjusting-screw removed. Fig. 4 is adetail in perspective.

In the accompanying drawings, which form a part of this specification, A represents a curtain-roller, one end of which is provided with a rigid spindle or journal, a, designed to engage with a suitable hanger, B. To this roller the curtain O is tacked, as in the ordinary manner. The opposite end ofthe roller A has secured to it a disk, D. E is an outer disk, which is secured to this end of the roller by means of a screw,F, such screw passing through both disks and a cylindrical rubber spring, G, into the end of the roller. Upon the outer face of the disk E, and preferably formed integral therewith, isa hub, H, portions of which are cutaway to form stops b, which are designed to engage with a spur or detent, 0, formed in the opening in the lower end of the hanger I, the latter being held in its proper position by the head of the screw F. The up per ends of the hangers B and I are adapted to hook upon hooks J,projecting from the window-frame, as shown in Fig. 1.

In practice, the parts being constructed and arranged as shown and described, supposing the curtain to be rolled upon the roller and it is desired to lower the curtain, this is accomplished by pulling down upon the curtain, the roller turning upon its pivotal point a at one end, the inner disk, D, rolling with the curtain as well as the screw F, which turns in the bearing in the lower end of the hanger I, the

disk E being prevented from turning by the engagement of one of these stops 1) with the detent 0. To prevent the curtain from unrollingby its own weight, the screw F is turned. in, so as to compress the rubber cylindrical spring G between the two disks, so that the frictional contact of such spring and the two disks will be sufficient to overcome the weight of the curtain. Such being the case, it will readily be seen that the curtain may be pulled down to any desired point, the friction referred to retaining it in its adjusted position.

To raise the curtainit'is merely necessary to pull down upon the cord K, which has been wound around the cylindrical spring between the disks as the curtain was pulled down, which causes the stop b to disengage from the detent G, such stops in the rotation of the disk E sliding up theinclined face of the detent 0. When the curtain has been raised or rolled up the desired distance, by releasing the cord the weight of the curtain causes a retrograde rotation of the roller until one of the stops 1) again engages with the detent.

The tension or compression of the spring between the disks may be regulated by the screw F for heavier and lighter curtains.

It will be observed that in winding the curtain up the tendency is for the roller to run to the forward end of the elongated opening in the hanger I, thejournal turning freely therein, while in the retrograde movement of the roller thejournal runs to the rear end of such hanger, and engages with the detent of the hanger, preventing the curtain from unrolling.

I am aware of the Patents Nos. 147,099, February 3, 1874, and 187,422, February 13, 1877, and make no claim to the constructions shown therein as forming part of my invention.

I attach importance to my cylindrical spring G,interposed between the two disks, and forming a drum on which the cord is wound. The spring thus serves a double function.

I am also aware of the Patent N 0. 243,465, in which a coiled spring is arranged around the spindle, and lay no claim to such construction. This coiled spring does not form a drum on which the cord is wound, and when the loo cord is wound on the spindle and over said spring it interferes with its operating asa tension-regulator. In my construction the winding of the cord on the spring in no wise inter feres with the usefulness of the same as a tenthe hanger I, having elongated opening and sion-regulator. detent c, of the roller A, disk D,se(-.ured there- I 5 What I claim as my invention is to, disk E, having formed integral therewith 1.
