PATENT HILLYARD A. STARR, OF EAST CHATTANOOGA, TENNESSEE.

SPECIFICATION forming' part of Letters Patent No. 718,737, dated January 20, 1903. Application filed June 2,1902. Serial No. 109,950. (No model):

To ttZZ whom, it may concern:

Be it known that I, HILLYARD A. STARR, a citizen of the United States, residing atEast Chattanooga, in the county of Hamilton and State ofTennessee, have invented certain new and useful Improvements in Means for Fastening Shades to Shade-Rollers; and I do declare the following to be a full, clear, and exact description of theinventiomsuch as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to means for fastening window-shades to shade-rollers.

The object of the invention is to provide simple and effective means of this character by means of which the shade will be securely held in position without the use of tacks and whereby liability of the shade pulling or tearing away from its fastening will be avoided.

With the above and other objects in view, which will readily appear as the nature of the invention is better understood, said invention consists in certain novel features of construction and combination and arrangement of parts, which will be hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a front elevation of a shaderoller embodying my invent-ion. Fig. 2 is an end elevation thereof, showing the shade drawn down to its fullest extent and also showing a portion of the roller broken away to expose the clasp. Fig. 3 is a perspective view of the clasp. Fig. a is a similar view of a different form of clasp.

Referring now more particularly to the drawings, the numeral 1 represents a spring shade-roller of ordinary form except as hereinafter described, the same being provided with the washer or cap 2 at one of its ends and the ferrule 3 at its opposite end, said ferrule forming part of the support for the dog-andratchet mechanism in the usual manner.

4. represents the shaft of the roller, which extends at one end through the ferrule 3 and coacts with the ordinary form of spring. (Not shown.)

In carrying my invention into practice I provide the roller with a longitudinal groove 5, which coincides with an opening 6 in the head 2 and extends beneath the ferrule 3. This groove is adapted to receive and retain a rod or wire 8, headed at one end and adapted to be passed through the opening 6 and thence beneath the ferrule 3, said head and ferrule thus acting as end supports to hold the rod in position. The upper end of the window-shade 7 is passed one or more times around the rod, which is then seated in the groove, and holds the end of the shade pressed firmly against the roller. To render the fastening absolutely secure, I provide a clasp to reinforce the action of the rod and to bear upon the shade. This clasp in the form shown in Figs. 1, 2, and 3 consists of a U- shaped plate of spring metal, which is bent or coiled into nearly'circular form and closely encompasses the roller, the said clasp being provided at its free ends with spurs or teeth 10 to penetrate the roller and hold said clasp in position. 'As shown in Fig. 2, the shade 7 passes from the rod 8 in one direction nearly around the roller and is engaged by the clasp 9, the free ends of which cross over the rod and act as supplemental fastenings to retain the same in place, while the spurs 10 are forced into the roller and serve to hold the clasp against longitudinal and axial play. It will thus be seen that as the rod 8 retains the ends of the shade in the groove and the clasp 0 retains that portion of the shade which is passed around the roller securely in place all liability of the shade becoming disconnected from the roller under any ordinary pull or strain will be entirely avoided. Of course it will be understood that any desired number of clasps may be employed and that where but one is used it is preferably located at or near the center of the roller in order to reinforce the action of the rod at a central point.

While the U or double form of clasp shown in Figs. 1, 2, and 3 is deemed preferable, in some cases the single or ring-shaped form of clasp shown in Fig. 4 may be employed and will render effective service.

By mounting the shade upon the rolls in the manner described when the shade is drawn downward to its fullest extent the dogs will be out of engagement with the rack, as shown in Fig. 2, thereby preventing the roller from being caught at this point and leaving the shade free to move up at the will of the operator. By this means the necessity of resetting the roll, which occurs when the shade is caught in the ordinary construction, is entirely avoided.

From the foregoing description, taken in connection with the accompanying drawings, it is thought that the construction, mode of operation, and advantages of my improved means for fastening shades to shade-rollers will be readily apparent without requiring a more extended explanation.

Various 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 my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with ash-ade-rollerprovided with a longitudinal groove and a retaining rod adapted to seat therein; of aclasp embracing the roller and bearing upon the rod and provided with spurs entering the roller, substantially as described.

2. A shade-roller provided with a head and a ferrule at its opposite ends and having a longitudinal groove extending beneath the ferrule and coinciding with an opening in the head, and a retainingrod adapted to be passed through the opening in the head and beneath the ferrule and to seat Within said groove and insertible and withdrawable longitudinally through the groove and head, substantially as specified.

3. The combination with ashade-roller provided with a longitudinal groove; of a shaderetaining rod seated in said groove, means for holding the rod in position, and a clasp adapted to embrace the roller and to bear against a portion of the shade passing therearound and to supplement the holding action of the rod, said clasp also bearing against the rod and supplementing the action of said holding means, substantially as set forth.

4. The combination with ashade-roller provided with a longitudinal groove; of a rod adapted to seat therein, and a clasp comprising a U-shaped piece of spring metal bent into nearly circular form to surround the roller and provided with spurs at its free ends, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
