CORD-FASTENER FOR SHADES AND THE LIKE.

Specification of Letters Patent.

Application filed July 26, 1907.

Patented Oct. 27, 1908.

Serial No. 385,613.

To all whom it may concern:

Be it known that I, Hnnny S. HUBBELL, a citizen of the United States of America, and resident of Chicago, Cook county, Illinois, have invented a certain new and useful Improvement in Cord Fasteners for Shades and the Like, of which the following is a specification.

My invention relates to improvements in fastenings for curtain and shade cords, and has for its object the production of a device of simple construction, yet one that will se curely hold the cord in place.

. A further object is the production of a device that can be readily applied, and one that will prevent the curtain and stick from slipping.

A further object is the production of a device that can be cheaply manufactured.

These and such other objects as may hereinafter appear are attained by my device, an embodiment of which is illustrated in the accompanying drawings, in which Figure 1 represents a perspective view of a window, a shade, and my device secured to the shade. Fig. 2 represents a perspective view of my improved device, showing in dotted lines a cord in position. Fig. 3 is a top plan view of my device. Fig. 1 is a perspective view of a modified form of my de vice. Fig. 5 is a vertical sectional view on line 55 of Fig. 4, looking in the direction indicated by the arrows.

Like numerals of reference indicate like parts in the several figures of the drawing.

My device is preferably formed from thin sheet metal cut and stamped in a peculiar manner.

The numeral 6 represents my device as a whole, comprising upper braces, ears or wings 7--7, also braces, ears orwings 88, and securing flanges 99 located therebetween and extending-at right angles to the braces or wings. The plate is formed with a semi-cylindrical portion extending vertically of the device, comprising an upper or larger semi-cylinder 10 and a lower semicylindeii' 11, a shoulder 12 being formed therebetween. The securing flanges 9 are preferably tapered to points 13, as shown in Figs. 2 and 5.

Referring to Figs. 1 and 5, in which I show a modified form of my device, it will be noted that the wings or ears 7 and 8 do not extend outwardly as far as those shown in Fig. 2. The securing flanges 9 are provided on either side with angularly turned portions 9 terminating in a point, these points being adapted to pass through the curtain and into the'stick, securely holding the clamp in place.

In fitting the device in place, the curtain stick is slipped in place in the lower fold of the curtain, and the device placed in the center in the positionshown in Fig. 1. The securing flanges 9 are forced through the cloth into the stick, and if desired, for the purpose of giving extra strength, the ends 13 of the flanges may be bent inwardly, locking the device in place. The upper and lower braces 7 and 8 fit closely against the cloth and stick, serving to hold the device in place as against any direct pull at right angles to the curtain. The curtain cord 14 is slipped through the cylindrical opening 15, a knot 16 being made in the end of the cord. The cord is then pulled through until the knot 16 engages the shoulder 12, which serves to prevent the knot from" slipping through the lower cylindrical opening.

If the device were subjected to a direct strain or pull at right angles to the stick, it would not be a difficult task to wrench the device from the stick; but when the cord is pulled outwardly in this fashion, the curtain as a whole is also pulled outwardly, putting no strain on the device. The device as used is always subjected to a straight pull downwardly or upwardly. Any tendency, therefore, to wrench the securing flanges 9-9 from the stick is resisted by the lower ears or braces 8-8 lying fiat against the stick.

When the curtain is of the variety that is pulled up from the bottom, the device is simply turned end for end, the shoulder then taking up the upward pull of the cord and holding the knot in place.

It is understood that other forms of this device may be constructed, and I do not limit myself to the precise form and contour of the device as shown.

I claim:

1. As a new article of manufacture, a curtain clamp formed from a sheet of metal and comprising wings or ears, securing flanges, and a continuous channel of varying diam eter formed therebetween.

2. As a new article of manufacture, a curtain clamp formed from a single sheet of metal comprising a pair of side wings or braces, a pair of securing flanges adjacent thereto, a second pair of wings or braces adjacent to said flanges, and a continuous vertical channel of varying diameter being formed between said pairs of wings and flanges.

3. As a new article of manufacture, a curtain clamp formed from a single sheet of metal, and having a continuous vertical channel of varying diameter formed therein adapted to receive and hold a curtain cord, upper and lower pairs of braces or ears projecting laterally from said channel, and a pair of pointed securing flanges extending inwardly at right angles to said braces and adapted to enter and engage a curtain stick between said upper and lower braces.

4. As a new article of manufacture, a curtain clamp formed from a single sheet of metal, and having a continuous vertical channel of varying diameter formed therein,

HENRY S. HUBBELL.
