CURTAIN-FIXTURE.

Specification of Letters Patent.

Patented Jan. 22, 1907.

Application filed February 10, 1906. Serial No. 300.434.

To all whom it may concern.-

Be it known that I, IRVING L. HoTALING, a citizen of the United States, residing at Riverton, in the county of Burlington and State of New Jersey, have invented certain new and useful Improvements in- Curtain- Fixtures, of which the following is a specifi cation.

This invention relates to curtain-fixtures of that type wherein a curtain-stick secured in or to the lower portion of the curtain is provided with a head at each end, carrying devices engaging a guiding groove of the window-franie and automatically resisting, through frictional engagement with the guide, the upward pull of the curtain-roller spring, while permitting the curtain and fix ture to be freely drawn downwardly.

The object of the invention is to provide a simple, easily assembled, and reliable device of this character, and to this end the invention consists of a fixture characterized, essentially, by the novel combination of a head onthe end of a curtain-stick carrying a support extending longitudinally of said head and in which the guide-rollers are mounted, said head. being movable relatively to said-support, so as to pass into and out of frictional holding engagen'zent with the upper roller.

My invention will be readily understood when considered in connection with the accou panying drawings, which illustrate a simple form thereof, and in which Figure 1 is an elevatlonal view of the lower end of a curtain equipped with my improved fixture, one end of the latter appearing in side elevation and the other in longitudinal section, and the fixture being shown in released position; and. Fig. 2 is a sim ilar view showing the fixture in holding position.

Referring to the drawings, 5 n. ay designate a curtain having formed in or applied to its lower end a transverse pocket 6, containing a tubular curtain-stick 7. In each end of the latter is slidably mounted a rod 8, the inner end of which is'reduced and encircled by a spiral spring 9, one end of this latter abutting against a stop 10 on the interior of the curtain-stick and its other end abutting against a shoulder 1 1 on the rod 8, whereby the latter is normally forced outwardly of the hollow stick.

On the outer end of the rod 8 is mounted a fixture-head, which in this instance consists of a tubular member or sleeve 12, within and longitudinally of which is slidably mounted .spring 9.

the guide-roller support, herein shown as consisting of a round bar or rod 13, the opposite ends of which project beyond the ends of the head 12 and are longitudinally slotted to provide forks 14, in and between which are mounted upper and lower guide-rollers 15. The upper end of the tubular head 12 is preferably countersunk or recessed in the plane of the roller and on a curve corresponding with the curve of the periphery of the roller, as shown at 16, to form a frictional seat for the latter, as hereinafter more particularly explained.

The tubular head 12 and its containedrollerecarrier 13 have a sliding movement relatively to each other, preferably limited by a pin-and-slot engagement between them,

the slot 17 being herein shown as formed in the wall of the tubular head and the cooperating pin 18 projecting therethrough from the carrier 13.

To the curtain-stick 7 may lie-attached,

rollers 16 into engagement with the bottom wall of the guide-groove of the casing by the The upward pull of the curtainroller spring raises the curtain-stick and the heads carried thereby, thereby bringing the upper ends of the heads into frictional engagement with the lower sides of the upper rollers, contacting the latter through the seats 16, the rollers and their support or carrier 13 normally tending to drop by gravity. This produces friction between the rollers 15 and their seats 16, tending to retard the free rotation of said rollers, which action also produces friction between the peripheries of the rollers and the wall of the guide-groove contacted thereby, whereby the curtain will be automatically detained in any position to which it may be manually adjusted.

It will thus be seen that the slidable head acts as a brake upon the upper roller as soon as the curtain is released and the curtainroller spring allowed to act. The curtain may be drawn downwardly, however, with perfect freedom, since a downward pull upon the curtain-stick relieves the braking effect of the head upon the upper roller, while the lower end of the head, inthe device shown, is not allowed to engage the lower roller,

owing to the limited relative movement afiorded by the pin-and-slct connection between the bead and roller support. However, the movement-limiting device is not essential, as the manual downward pull is easily suflicient to overcome the retarding effect on the lower roller.

So far as I am aware my present invention constitutes the first instance in the art of a structure wherein a roller support or carrier is mounted upon the fixture-head with capacity for a sliding movement relatively thereto so controlled that the upward move ment of the curtain carries the head into frictional or braking engagement with a. roller, and hence the invention is not limited to the particular embodiment .iierein disclosed except to the extent indicated in specific claims.

I claim 1. A curtain-fixture comprising a curtain stick, a bead carried thereby, a roller-support extending longitudinally of and carried by said head, and a roller carried by said support, said head and roller-support having relative sliding movement whereby braking engagement between t le head and the roller is established under tne upward pull of the curtain, substantially as described.

2. A curtain-tlixture comprising a curtain stick, a tubular iiead carried thereby, a

roller-support slidably mounted in said tubular head, and a roller carried by said support and peripherally engaged by said head under the upward pull of the curtain, substantially as described.

3. A curtain-fixture comprising a curtainstick, a tubular head carried thereby, a roller-support slidably mounted in said tubular iiead, rollers mounted in the upper'and lower ends of said roller-support, and means limiting the relative sliding movement between said rollersupport and head, substan tially as described.

4. A curtain-fixture comprising a curtainstick, a tubular head carried tliereb y, a roller-support slidably mounted in said tubular head, and a roller carried by the upper end of said roller-support, said tubular head having its upper end transversely recessed conformably to the periphery of said roller whereby to act as a brake on the latter under the upward pull of the curtain, substantially as described 5. A curtain-fixture comprising a curtainstick, a spring-pressed rod carried thereby, a head on the end of said rod, a roller-support slidably carried by said head, and a roller I mounted on the upper end of said support, substantially as described.

6. A curtain-fixture comprising a tubular curtain-stick, a spring-pressed rod slidably mounted therein, a tubular head on the end of said rod, a roller-support slidably mounted in said head, and a roller mounted in the upper end of said roller-support, substantially as described.

7. A curtainfixture comprising a tubular curtain-stick, a spring-pressed rod slidably mounted therein, a tubular head on the end of said rod, a roller-supp ort slidably mounted in said head, and rollers mounted on the upper and lower ends of said roller-support, substantially as described.

8. A curtainfixture comprising a tubular curtain-stick, a springpressed rod slidably mounted therein, a tubuL *ead on the end of said re d, a roller-support slidably mounted in said head, rollers mounted in tire upper and lower ends of said roller-support, and means limiting the relative sliding movement between said roller-support and head, substantially as described.
