CURTAIN-FIXTU RE.

SPECIFICATION forming part of Letters Patent No. 530,079, dated December 4, 1894.

Application filed January 12, 1894- Serial-No. 496,644. (No model.) I

To aZZ whm it may concern:

Be it'known that we, STEWART LEE BERG- sTREssER and CHARLES E. MIGNOT, citizens of the United States, residing at Smethport,

in the county of McKean and State of Pennsylvania, have invented a new and useful Curtain-Fixture, of which the following is a specification.

This invention relates to curtain fixtures; [O and it has for its object to provide certain improvements in curtain fixtures whereby the same may be readily raised and lowered, automatically, to cover and uncover the window on which they are arranged, and which may be held stationary in any adjusted position. To this end the main and primary object of the present invention is to provide certain improvements in curtain fixtures to secure the result noted, and also to provide novel and efficient means for not only checking the roller devices at any adjusted position, but also for covering and protecting the roll portion of the shade. I

With these and other objects in view which 2 5 will readily appear as the nature of the in vention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

In the accompanying drawings-Figure 1 is a front elevation of a window frame showing our improved curtain fixture applied thereto. Fig. 2 is a detail in perspective of the fixture removed from the window frame. 3 5 Fig. 3 is a central vertical longitudinal sec tional view of one end of the fixture. Fig. 4

is a detail sectional view on the line a:0c of Fig. 1. Fig. 5 is a detail end view of the fixture, one of the caps being removed. Fig. 6

0 is a detail modification showing how the fixture may be arranged at the upper end of a window-frame. Fig. 7 is a detail in perspective of the sliding stop-arm.

Referring to the accompanying drawings,

4 5 A represents a window frame of the ordinary construction, to the top of which is suitably secured the free end of the curtain shade B,

the other end of which winds and unwinds on the ordinary spring-actuated shade roller O. The spring actuated shade roller is of the usual construction with the exception that in the present invention the same dispenses with the usual arresting pawls whereby it will be free, under the tension of -its spring, to

wind up the curtain thereon, automatically,

tions which will telescope, as illustrated in the drawings, so that the same may be laterallya djusted so as to be accommodated to different lengths of shade rollers. The said casing barrel is provided with the longitudinal top slot E, extending from end to end in order to provide a free passage for the curtain shade in winding and unwinding on the roller, and at each side of the top slot the metal forming the barrelis curled to form roll beads F, which present a perfectly smooth edge to the shade and prevent the same from being impaired or quickly worn.

The cylindrical casing barrel D, is provided with opposite open ends over which areremovably fitted the open flanged barrel caps G, one of which is provided with a circular o en 3 ing g, to receive the turning bearing spindle g, on one end of the roller, and the other bearing cap is provided with a squared socket or opening H, at its inner side to receive the squared spindle h, which projects from one end of the shade roller, and is designed to be held stationary in order that the spring of the roller may be effective in its operation.

The shade roller 0, in the present invention, is provided at one end thereof with a radial series of projecting stop lugs I, which 5 are adapted to be engaged at one side by the outer flanged end J, of the sliding stop arm K. The sliding stop arm K, is provided in the top thereof with alongitudinal guide groove L, which is engaged by the bottom outer edge of one of the roll beads F, which is sufficiently close to the body of the barrel in order to engage the groove of the stop arm and hold the same to a sliding movement on the barrel, and said stop arm is manipulated by grasping the finger pin M, standing 0E from the inner end thereof. The outer flanged stop end J, of the stop arm is adapted to slide in the slot N, formed in one of the barrel caps and one end of the barrel itself, so that such flanged stop end may be thrown into and out of the path of the stop lugs I, of the roller, whereby the same may be checked at any point or allowed to freely revolve within the casing barrel.

It will be apparent that by manipulating the stop or check device for the roller with one hand, the same may be either allowed to automatically wind up the curtain thereon, or may be drawn down against the tension of its spring to lower the curtain and may also be checked at any point desired.

It will be obvious that the herein-described curtain fixture may be arranged so that the casing barrel and the check device carried thereby may be mounted in a stationary position at the top of the window frame and the curtain raised and lowered in the ordinary manner, and that the same may be used in connection with any kind of curtain. We will also have it understood that other changes in the form, proportion and the minor details of construction, may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

,Having thus described the invention, what is claimed, and desired to besecu red by Letters Patent, is

1. The combination of a cylindrical casing having a curtain slot and a roll bead at both edges of said slot, an ordinary pawlless springactuated shade roller mounted for rotation inside of said casing and provided at one end with a series of projections, and a sliding stop arm mounted to slide on the casing beneath the edge of one of the roll beads and adapted ends of the casing and having openings, an ordinary spring-actuated shade roller mounted for rotation within the casing and having its spindles engaging the openings in said caps. the shade secured fast at its upper end and winding and unwinding on the roller, and a sliding stop device mounted on the casing and adapted to engage the roller, substantially as set forth I 3. In a curtain fixture, the suspended springactuated shade roller having stop lugs near one end, the slotted casing barrel inclosing the roller therein and provided with roll beads and a slot at one end, and a grooved stop arm adapted to slide on the casing below the lower edge of one of said roll beads and having a stop end working in the slot at one end of the casing and in the path of the stop lugs on the roller, substantially as set forth.

4. In a curtain fixture, the combination of the suspended roller having a radial series of projecting stop lugs at one end, the cylindrical casing inclosing the roller therein, and a sliding stop arm mounted on the casing and having a flanged stop end adapted to be thrown in and out of the path of the stop lugs on the roller, substantially as set forth.

In testimony that we claim the foregoing as our own we have hereto aifixed our signatures in the presence of two witnesses.
