CURTAIN-ROLLER.

SPECIFICATION forming part of Letters Patent No. 278,038, dated May 22, 1883.

Application filed May 10, 1882. Renewed April 3, 1883. (No model.)

To all whom it may concern Be it known that I, WALTER B. NoYEs, o

Saginaw, in the county of Saginaw and State- The nature of this invention relates to cerlain new and useful improvements in the construction of curtain-rollers of that class wherein the curtain is rolled upon theroller by means of a side cord, the object of the invention being to construct a roller in such manner that the curtain can be lowered by pulling down upon the same, and that will remain at its adjusted position without the employment of the cord, excepting in raising the curtain.

The invention consists in the peculiar construction, arrangement, and various combinations of the parts, all as more fully hereinafter set forth.

Figure 1 is a central longitudinal section through the end which carries my improvement. Fig. 2 is a detail perspective, showing the operation of the stop-dog; Fig. 3 is a section through the opposite end of the roller.

In the accompanying drawings, A represents a wooden roller, in one end of which is formed a recess, a, by boring out that end of the roller.

B representsaspool provided with the flange b and with a plug, 0, which latter fits closely into the mouth or end of the-recess a, and is secured therein in any convenient manner. This plug 0 is provided with a central passage to inclose the adjustable plug d, which is provided with a head, e, and around this plug (1, between the head e and the inner face of the plug 0, is placed a coil-spring, f, the ends of which bear against the inner face of the plug 0 and the head 0.

0 represents a flange-plate provided with a hub, h, which hub is slightly tapering, and enters a correspondiugly-shapedhole in the outer end of the spool 13. This flange-plate is secured to place by means of a screw, D, which passes through the hub of the flan ge-plateand screws into the end of the plug d; and it will be seen that by means of this screw a greater or lesser tension may be brought to bear upon the springf, thus regulating the frictional con-. tact between the spool B and the flange-plate O, as may be desired. The hub of the flangeplate 0 is centrally recessed to receive the slotted stud E of the bracket F when the curtain is hung, such bracket being secured to the window-frame, as in the ordinary manner.

G is a dog or pawl, which is pivotally secured to the outer face of the flange-plate O, and in the operation -of the device thisdog engages with the slot in the stud Eof the bracket. For a bearing upon the opposite end of the journal, which is to rest within a suitable bracket secured to the window-frame as in the ordinary manner, I employ a block, H, preferably of hard wood, and of the same diameter as the roller to which it is to be applied, and through the center of this block 11,1 drive a pin, I. To secure this block to the end of the roller A, I place the block H upon the end of the roller, which necessarily centers or gives center for the journal-pin I, which I then drive into the end of the roller -A, as shown in Fig. 3, thereby securing both parts together without the necessity of using brads or nails, as in the ordinary manner; and in case I have cut the roller a little too long or too short the pin I "may be driven so as to accommodate the roller to the brackets.

In hanging a curtain provided with a roller of this construction, the brackets first having been put up, the cord, one end of which is madet'ast to the spool B, is left unwound while the curtain is rolled upon the roller, and the bearings are placed within the brackets. By then pulling down upon the curtain it will be seen that I wind the cord upon the spool, and in pulling upon the cord I necessarily raise the curtain or wind it upon the roller. YVhen it is desired to lower the curtain without the means of the cord, I merely pull upon the curtain,.which allows the roller, with the spool 13, to turn upon the hub of the flange-plate C, the spring exerting suflicient force to cause frictional contact between the parts and retain the curtain in its adjusted position without disturbing the engagement of the dog with the bracket.

What I claim as my invention isplate 0, and screw D, substantially as and 1. The combination,with the rollerA,having for the purposes described. a recess, a, and the hollow spool B, secured to 3.
