BENJAMIN L. GOLDSMITH, OF BALTIMORE, MARYLAND.

WINDOW-SHADE.

SPECIFICATION forming part of Letters Patent No. 258,410, dated May 23, 1882.

Application filed February 13, 1882. (No model.)

To all whom it may concern:

Beitknown that I, BENJAMIN L.GoLDsMrrH, of Baltimore city, State of Maryland, have invented certain new and useful Improvements in Window-Shades; and I hereby declare the same to be fully, clearly, and exactly described as follows, reference being bad to the accompanying drawings, in which Figure l is an elevation of the end of a window-shade embodying my invention. Fig. 2 is a cross-sectional view through the lower bar or rod, and Fig. 3 is a similar view through the roller.

The object ofmy invention is to remedy what has heretofore been afruitful source of annoyance, trouble, and loss of time, due to defects in the modes of attaching window shades or curtains to the lower bars and rollers as heretofore practiced. It has been customary to fold the lower edge of the fabric and stitch it down, forming a tube, through which the lower bar was thrust. It was secured in place, if at all, either by stitching at the ends or by the screw-eye to which the tassel was attached. Sooner or later the stitching would tear, necessitating the formation of a new tube at the bottom of the curtain, when the operation was repeated, unless the curtain first wore out elsewhere. This was generally the case. Indeed, the first break was liable to occur in another placenamely, at the roller-and my invention is designed to remedy existing defects in that place also.

Heretofore the blind or curtain has either been attached to the roller by tacks or by inserting the fabric in a slot or groove in the roller and securing it in place by a strip. In either case the blind was very apt to tear loose when drawn out to its fulllength, by reason of the heads of the tacks cutting through, or else by reason of the fabric being bent back on it self at right angles over the edge of the slot or strip.

In carrying out my invention I coat the lower end of the curtain A with a solution of caoutchouc in bisulphide of carbon, turpentine, or equivalent solvent; or I may use any other tough and strong cement, and fold it around the bar B, as shown, the end a of the curtain being, by preference, first folded upon itself to make a smooth finish. The cement b firmly secures the end of the curtain to the body and to the bar. The space b is filled with the cement, which is pressed out from between the curtain and the bar as the former is folded round the latter, and a strong joint is thereby formed. The trouble and expense of the stitching are avoided, the curtain will not rip nor tear loose from the bar, and the latter is secured in place.

In attaching the curtain to the roller 0 the end of the curtain is coated with the cement b, and it is folded round the roller and secured as before. The end a in this case is, by preference, not folded on itself, as the triple thickness ofmaterial which would thereby be formed would be so stiff as to cause the fabric to bend at too sharp an angle over its edge when the curtain is wound on the roller. The double thickness, as at a, having the tough cement b between the folds, forms a flexible joint, stiff enough not to bend sharply back upon itself, and not so stiff as to limit the bending to the point at which the double thickness of fabric ends. As a result the curtain will not tear loose from the roller. 7

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A windowshade folded round its bar or roller and lapped upon itself, and having a tough elastic and flexible cement between the shade and bar or roller and the lapped por- BENJAMIN L. GOLDSMITH.
