SPRING CURTAIN-ROLLER.

SPECIFICATION forming part of Letters Patent No. 240,191, dated April 12, 1881. Application filed February 19, 1880.

To all whom it may concern:

Be it known that I, CHARLES T. SEGAR, of Utica, in the county of Oneida and State of New York, have invented a new and valuable Improvement in Spring Curtain-Fixtures; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representationof a longitudinal section of my improved fixture, and Figs. 2 and 3 are details.

Thisinvention has relation to spring curtainrollers; and it consists in the construction and novel arrangement of parts, as hereinafter shown, described, and particularly pointed out in the claim.

' separated from the central square hole, I).

B indicates the disk-shaped box or springcase, consisting of a circular rim, 0, and a centrally-perforated outer wall portion or plate, d, which is extended on the side next the window, as indicated at e, and provided with a fasteningflange, f, through which screws can be passed to attach the fixture to the windowframe. This box has very little transverse depth, only sufficient being required for the reception of the coiled ribbon-spring g, the spring disk guard h, and the spindle-flange which plays between the disk-guard and the face or cover k of the box, which is next the roller end, as shown in the drawings. One end of the spring 9 is attached to the rim of the box and the other or inner end to the spindie 8, which is centrally located in the box and passes transversely through it, having narrow journals 1 l, which bear in the circular central openings m m of the side wall and face of the box. At one end of the spindle, projecting outward beyond its journal, is a squared lug,

n, which is designed to engage with the hole b of the end plate, a, of the roller. Next to this journal Z is the disk-shaped flange p of the spindle, themargin of which is notched at opposite points, as indicated at q, these notches being slightly beveled atone side, near the margin, so that the end ofthe pawl 2 which is pivoted to the face or cover 7c of the box, and which is also beveled on one side; will readily pass the notches when the curtain is pulled down, and will engage one of them when the curtain is brought into the required position. The end of the pawl z is also somewhat beveled on its point portion, as indicated at i, so that under the rapid action of the springin raising the curtain it will pass over the notches in the'opposite direction, fallinginto engagement with one of them when the curtain is stopped.

Between the flangepof the spindle and the outer journal, I, is the core or heel portion 1),- to which the inner end ot'the spring is secured, and on which it is wound when the curtain is actuated by pulling it down.

core '0, which is of larger diameter, by a shoulder, a, which keeps the outer wall of the box from pressing on the spring and impeding its action.

It represents a large inner disk, having a central opening of suflicient size to on the core c, this being done before the spring 9 is attached thereto, so that the disk will form a guard for the spring and keep it from interfering with the notched flange of the spindle.

I am aware that a short shaft mounted in a case carried on one of the brackets, and the projecting end of which short shaft engages with and supports one end of the curtain-roller, and imparts thereto the effect of the spring, has been used in combination with a pawl mounted on the fixed portion and engaging a notch in the short shaft, as maybe seen in.

Patent No. 195,962, of October 9, 1877, and I desire to make no claim herein for said construction, broadly, but wish to limit myself to the construction herein shown and described,

and hereinafter particularly pointed out in the claim.

Having described this invention, what I claim, and desire to secure by Letters Patent, iS-

In a springroller-fixtnre for curtains, the combination of the disk-shaped box B, having the Thejournal l is be passed action of the pawl and the In testimony that 1 claim the above I have hereunto subscribed my name in the presence of two witnesses. 1
