HARRY T. W'ARNER, OF NEWARK, NEW JERSEY.

CURTAIN-BRACKET.

SPECIFICATION forming part of Letters Patent No. 225,894, dated March 23, 1880. Application led February T, 1880.l

1o whereby the motive power is located in the bracket ot' the fixtures, instead of in the roller, as has hitherto been done, actuating the roller therefrom.

The old style ot' seltacting shade-fixtures,

in which the motive-power is contained in the roller, is subject especially to two objections:

First, that at'ter having been cut down to tit one window it cannot be used for another of greater width. My invention obviates this 2o dil'lculty, as the motive power is connected with the bracket, and on changing' to a wider window it is only necessary to procure a new ro1lerstick at the cost of a t'ew cents.

Second, another objection, and a great one,

to the self-acting rollers, in which the spring the bore to put the spring in leaves very little wood on which to tack the shade. Ihis necessitates the use of very small tacks to prevent rlhese small fourounce tacks are frequently inadefpiate to holding heavy shade materials to the roller, and it is a common occurrence for shades to pull from the roller the iirst time they are used.

The roller in my case heilig solid throughout,

this objection does not hold good.

Figure 1 is a front view ot' bracket, roller, and shade. Fig. 2 is a longitudinal section, showing my improvemex-its. Fig. 3 is an end Figs. it and 5 are views showing a modification ot' the stop devices.

The bracket for one end of the roller A is constructed with a case, B, having the feet In this case, which may be two and a halt' inches long, more or less, is coiled a long stretch of elastic wire, D, about twenty-live feet on the spindle E, and to get this length of spring in so short 5o a space it is coiled one or more times over -itselt' on the spindle.

One end ot' the spring is secured to the inner end of the spindle and the other end to the case; or it may be reversed to the oppols in one end of the roller, is that the size of` site end of the spindle, or to the wheel F, which wheel, being part of the spindle. is made to turn in and is held in position by the end ot the case.

The inner end of: the spindle has a bearing, il, in the ease.

The wheel .F has a recess or rabbet, I, in the outside ot' the periphery, in which a pawl, J, which is attached to the end of the case, is made to rest. In the bottom of this rabbet is one or more notches, K, to engage the pawl and hohl the shade at any desired height.

'Ihe wheel has a rectangular or other shaped recess, L, not round, to receive the projection o from the roller end, which projection has the same shape transversely as that of the recess. \Vhen the shade is drawn down the projection t turns the spindle and coils the spring on it.

The spring as a motive power, in combination with a bracket, may be employed otherwise than in a case, for in the place ot' a case there may be an open frame for holding and operating it; and the mechanism for stopping the shade may be placed between the bracket and roller on the outside of the case and the same result be secured in both cases, the invention being in uniting the motive power with the bracket and having suitable mechanism for connecting it with the roller withoutmakiug the fixture large and ungainly in appearance.

Instead of the pawl and ratchet working as described, the pawl may be attached to the wheel, which revolves in the case, and the notch may be in the ease. (See Fig. 4.) 0r, instead ot' the pawl, a small piece ot' metal, a parallelogram in shape, with square edges, working in ways attached to the end ot' the case, and engaging in notches in the wheel, as seen in Fig. 5, may be used.

The bracket on the opposite end ofthe roller will be an exact pattern ot the one containing' the spring, and,if desired, it may contain part of the mechanism. Therefore TWhat I claim as my invention, and desire to secure by Letters Patent, is-

'Ihe ease B, spindle E, spring I), wheel F, and pawl J, combined substantially as and for the purpose set forth.
