ATTACHMENT FOB. WINDOWSHADES.

Application filed June 21, 1916.

To all whom it may concern.-

Be it known that I, EMIL WINTERER, a citizen of the United States, residing at Manchester, in the county of Hillsboro and State of New Hampshire, have invented certain new and useful Improvements in Attachments for VVindow-Shades, of which the following is a specification.

This invention relates to attachments for window shades, and more particularly to an attachment for a window shade to prevent overwinding of the same.

One of the main objects of the invention is to provide an attachment of the characterstated of simple construction and operation. A further object is to provide an attachment which can be manufactured in large numbers at very small cost. Further objects will appear from the following detailed description.

In the drawings:-

Figure l is a side view of the invention as applied,

Fig. 2 is a perspective view of the attachment, and

Fig. 3 is a modified form of the invention.

The curtain pole 1 is mounted in brackets 2 secured to the window casing 3, in the usual manner, and carries a shade l of any suitable construction. This shade is turned back upon itself, at its lower end, to receive the usual rod or stick 5.

To this stick, at the longitudinal center thereof, I secure my braking attachment designated by 6. This device is formed with a book 7 which is adapted to fit tightly about the stick 5, and is provided with an aperture 7 at its lower end to receive the usual screw eye 8 which is threaded into the stick 5, the pull cord 9 carrying the ring 10 being secured through the eye 8, as is usual. The body 11 of the braking device is curved upwardly and backwardly, the outer end being coiled upon itself to form a tube 12. 11 I provide a cushion stud 13 of rubber or other suitable resilient material. The hook 7 and body 11 are formed integral, as shown, the whole device being made from sheet spring steel, or the like, so as to be durable and have a great deal of resiliency.

If, in winding up the shade, the pull cord 9 is accidentally released at a point where the dogs which are provided on roller 1 Specification of Letters Patent.

and act in the usual manner, have not locked the roller against rotation, the shade will fly upward due to the sudden release of the roller. This results in overwinding of the shade causing the cord to wrap around the shade and roller and thus become entangled with the same. This is a well known fault with shades of the ordinary type and is often experienced when the shade is ac cidentally released as above described. With my attachment secured on the shade, if the shade be released in this manner, the cushion stud 13 will engage the under face of the top board 3 of the window casing thus preventing overwinding of the shade. Due to the resiliency of the stud 13 and the member 6, damage to the shade from stopping it too suddenly is effectually avoided.

In Fig. 3, instead of securing the device 6 to the shade stick 5 by means of the screw eye 8, I provide it with a spring clamp let in place of the hook '7. This clamp is adapted to fit tightly about the stick 5 and thus secure the attachment thereto.

By having the upper outer end of the device of tubular shape all danger of its engaging curtains, which may be hung inside of the shade, is avoided, as there are no sharp projections to engage in curtains or the like. The outward curvature of the body 11 of the attachment will depend largely upon the type of shade with which it is used, it being such as to bring the cushion stud 18 in proper position to engage the under sur face of the top board 3 of the window casing 3, as above described. As a large majority of shades and brackets are of standard construction, my device can be made of a particular standard size and shape, but may be varied to suit special sizes.

In addition to exerting a braking effect upon the shade if accidentally released, my device is also adapted to prevent rattling of the shade in the event of the window being opened at the top and the shade being in a raised position, such as it occupies in Fig. 1. In this case, the cushion stud 13 is in frictional engagement with the top board 3 of the window casing and efl'ectually prevents free swinging in and out of the curtain under the influence of the incoming air current, thus preventing any rattling such as would occur if the shade were perfectly free.
