DEVICE FOR ATTACHING CURTAINS TO ROLLERS.

SPECIFICATION forming part of Letters Patent No. 320,290, dated June 16, 1885.

Application filed February 18, 1885. (No model.)

To all whom it nm concern:

Be it known that 1, Joint Boson, a subject of the Emperor of Germany, and aresident of New York, N. Y., have invented certain new and useful Improvements in Devices for Attaching Curtains to Rollers, of which the following is a specification.

My invention has relation to improvements in devices for attaching wimlow-curtains to their rollers, and has for its object the provision of means whereby the window-curtain may be attached to the roller with great facility and dispatch, and without the ne(e3sity of tacks orlike fastening devices.

My invention consists in the novel construe lion, combination, and arrangement of devices, hereinafter ful ly described and specifically claimed, whereby the curtain may be easily and speedily attached to the roller, and, if necessary, adjusted thereon after it has been secured in position.

In carrying my invention into effect I employ, in place of the tacks or other fastening devices heretofore used, a number of split rings, of metal or other suitable substance, which are slipped onto the roller, with one end of each such ring embracing the edge of the curtain. In connection with the rings I propose to employ, when found necessary or desirable, a wire or cord, which is hemmed into the edge of the curtain and fits ina longitudinal slot in the roller. In connection with the split rings, I also propose to fashion the plates which carry the journals of the rollers, and (where a spring is not used) the cord for rolling or unrolling the curtain, with sleeves having a split at one side, which embraces the end of the curtain in the same manner as the split rings above referred to, and serves also to retain the curtain in place on the roller and permit of its adjustment thereon, as will be presently described.

Referring to the accompanying drawings, Figure,1 is a front view of the roller and the curtain attached thereto, the latter being unrolled; Fig. 2, a view of the roller with my improved fastening device in position, the curtain being removed; Figs. 3 and 4, details of the fastening devices; Fig. 5, a view of a spring-roller with my improvements applied thereto.

Adesignates the roller, which is of the usual form and material, and is provided with a longitudinal slot, a, adapted to receive the edge of a curtain, B, and a wire or cord, 1), which is hemmed into said edge.

0 designates the metallic pulley, which is usually attached to one end of the roller and receives the cord for operating the same, and is formed with the journal or axle 0, upon which the roller is j ournaled.

D designates the plate at the other end of the roller, which is also formed with a journal or axle, d.

As ordinarily constructed these parts consist each of a flat plate fastened to the end of the roller by means of small nails, and their attachment to the roller forms no small part of the labor involved in putting up windowcurtains. In addition to their function as journals for the roller and pulley for the cord, I propose to use these parts of the curtain-fixture as a means of attachment for the curtain in connection with the split rings and groove above referred'to, and for this purpose I form each of them with a sleeve, E, which is slipped on the roller and fits with sufficient tightness to cause the roller to turn with them, thereby dispensing with the fastening-nails. Each of the sleeves E E is formed with a slit or slot, F, on one side, and when the curtain is in position on the roller the sleeve on one side of this slit embraces the edge of the curtain and binds it tightly in the groove or slot to. The sleeves E E, in addition to the above uses, serve, also, as a means for adjusting the length of the roller, as they may be slipped out on the roller aconsiderable distance, so as to materially increase the length of the same, thereby obviating the necessity of cutting the roller of the exact length requisite to fit the fixtures on the window-jambs.

G designates the ring which I employ for securing the curtain at the middle. Said ring is made of any appropriate material-as spring sheet metal or wire-and may be of any de sired width. This ring is slipped on the roller before placing the sleeves E E in position, and it is made of such diameter that it will clasp the roller with considerable force. A split,

is formed at one side of the ring to permit of the entrance of the edge of the curtain to the slot or groove said split being as wide or slightly wider than the said groove, and parallel thereto.

Operation: The end pieces and the split ring being in the position shown in Fig. 2 of the drawingsthat is, with the slots F F and the split 9 in line with the groove a in the rol1erthe wired edge of the curtain is placed in the groove a, and the sleeves E E and the split ring G turned around into the position shown in Fig. 1. The edges of the sleeve and of the split ring now firmly clasp the edge of curtain and retain it in position in the groove a, and the curtain is ready to be placed in position on the window in the usual manner. If it is found, after placing the curtain in position, that it does not hang down or roll up properly, it is only necessary to turn the ring or either of the sleeves slightly in one direction or the other until the curtain is clasped to the roller on a perfectly straight line. This operation may be effected with great facility and without the necessity of removing the roller from-the bearings.

In Fig. 5 of the drawings, where I have shown myimprovement as applied to aspringroller, it will be noted that the cord-pulley is dispensed with, and that I place at that end of the roller a split ring similar to the ring in the middle of the roller.

In some cases the wire in the edge of the curtain may be dispensed with, the edge being placed in the groove; or the groove may be dispensed with, and the curtain attached to the roller in any desired manner, the split ring and the split sleeves being employed merely to adjust the curtain, as before described; but I prefer to employ both the groove and the wire, as they greatly facilitate the attachment of the curtain to the roller.

When a very wide or heavy curtain is to be attached to a roller, two or more of the split rings may be employed; but for the curtains of the ordinary size one ring and the two end sleeves will be found sufiicient.

I am aware that it is not new, broadly, to employ a split metallic ring or a split collar at the end of the roller for the purpose of attaching a curtain.

Having described the construction and operation of my invention, I claim- 7 1. In a device for attaching curtains to rollers, the combination, with a curtain having a corded or wired edge and a roller having a groove to receive the end of a curtain, of a split ring adapted to embrace the end of the curtain and hold the same in said groove, substantially as described.

2. In a device for fastening curtains to rollers, the combination, with the roller having a longitudinal groove, a, and the split ring G, of the curtain having a corded or wired edge adapted to fit in said groove, substantially as described.

3. In a device for fastening curtains to rollers, the combination, with a curtain having a corded or wired edge and a roller having a longitudinal groove,a,of the end piece or plate, D, having an axle, d, the sleeveE on said plate formed with the slot F, and the ring having a slit, 9, all constructed and arranged substantially as described.

In testimony that I claim the foregoing as my invention I have signed my uame,in presence of two witnesses, this 7th day of February, 1885.
