No. 338,065. Patented Mar. 16. 1886.

SPRING CURTAIN-ROLLER.
PECIFZOATION forming part of Letters Patent No. 338,065, dated March 16, 1886.
Application ti ed September 30, 1885. Serial No. 178,674. (No model.)
To all whom it may concern.-
Be it known that I, JONATHAN HARRIS, of Grand Ledge, in the county of Eaton and State oflVIichigan,have invented new and useful Improvements in Spring Curtain-Rollers; 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 a part of this specification.
Thisinvention relates to certain new and useful improvements in springcurtain-rollers; and the invention consists in the peculiar con struction and arrangement of the parts, by means of which the curtain can be stopped at any desired point, all as more fully hereinafter set forth.
Figure 1 is acentral longitudinal section through my improved roller. Fig. 2is a perspective view of the end of the roller with the cap removed, showing the arrangement of the locking mechanism. Fig. 3 is an end elevation of the spring end with cap removed.
In the accompanying drawings, which form a part of this specification, A represents the spring end of a curtain-roller. This roller is hollow for a portion of its length, into which hollow isinserted the spindle B, around which is placed a coil-spring, O, the inner end thereof being secured in a slot, a, in the inner end of the spindle, the projecting and slotted end of the spindle entering a socket, l), at the bottom of the bore.
F is the other end of the roller,'similar to the part A, except that it is open at one end only.
G is an intermediate section of less diameter than the sections A F. The end 9 of this intermediate section is secured in the bore of the part A in any convenient manner, and is provided with a socket, h, to receive the slotted end ofthe spindle B. The other end works looselyin the bore of the section F. The solid end of the section F is provided with a spindle or hearing, H, having a groove, 71, while the outer end of the spindle B is provided with a similar groove, 76. By this construction I provide an extensible roller which requires no fastening means to hold the parts in their adjusted position, as the same will be held in place by reason of the grooved spindles en- I gaging with their holding-brackets.
To insure the perfect working of the curtain, and to prevent the same from sagging between the sections, I provide an adjustable sleeve, 1, of same diameter as the sections A F on the section G, by which it will be seen that I provide an even bearing for the curtain through out its entire length.
D is a plug, preferably of metal, which is inserted in the bore at the open end of the roller, as shown, and between this plug and the inner wall of thebore the outer end of the spring 0 is secured in any convenient manner, so that the spring is rigidly secured at that end. Through the center of this plug D is a suitable 0pening,through which the outer end of the spindle B projects. The outer face of the plug is recessed, as shown, to receive upon one side the small removable rod 0, which pre- Vents the spindle B from being displaced, and upon the opposite side the wall of the recess is inclined and cut away, as shown, to receive the bullet or sphere of metal (I, which rests within the groove e in the periphery of the spindle. This plug, with its removable parts, is secured in place by means of a cap, E, through which the end of the spindle projects, this projecting end being designed to engage with any suitable stop or fastening upon the window or frame that will prevent the spindle from rolling as the curtain is operated, the opposite end of the roller being provided with any suitable pivotal point to engage with a suitable bracket.
In practice, as the curtain is pulled down the roller rolls or turns upon its pivotal point, the tendency of the spring in uncoiling being i to turn the roller back, and thus compress the ball between the incline and the groovein the spindle, thereby clamping such spindle firmly between the ball and the short rod above described, which also lies partially within such groove. WVhen it is desired to raise the curtain, or allow it to be rolled down the roller under the action of the spring, the curtain is first pulled down slightly to disengage the ball, when, ifallowed to roll quickly, the centrifugal force will throw such ball into the cut-away portion of the recess and allow the curtain to be wound up on the roller.
It will be observed that in this construction 5 the spindle and spring can be removed from the roller without marring or breakingthe roller in any way, as may be required, for inserting a new spring, there being none of the parts-nailed or bradded together, as in the old construction. It will also be observed that the plug D serves to retain the outer end of spring 0 between itself and the wall of the section A.
The end F of the roller is bored out for a portion of its length to receive the diminished portion G of the end A, which may be formedas an integral partthereof; or it may be formed from a separate piece rigidly secured to the inner end of the part A. Upon this rod or part G, I slip a section of a roller, H, the diameter of which is the same as that of the sections A and F. In this construction it will be seen that both ends of the roller are adapted to be hung without cutting, and in order to lit the roller to a window the end F is removed and the end of the rod G cut off sufficiently, so that when the parts are again put together the roller will be of the desired length to fit the window upon which it is to be used.
I am aware of the English Patent No. 731 of 1856, which shows a telescopic roller but no sleeve to prevent the sagging of the curtain between theend sections when the roller is extended, and such construction I disclaim; neither do I claim the construction shown in the Patent No. 302,379, July 22, 1884.
What I claim as my invention is 1, The combination of the end sections, A
F, of like diameter, of theinterinediate section, G, of less diameter than said sections A F, and the sleeve I, of the same diameter as the end sections, substantially as and for the purpose specified.
2. In a spring curtainroller, the combina- 'tion, with the roller, of a plug inserted in one JONATHAN HARRIS.
