CROSS-BAR FOR ROLLER-CURTAINS.

Application filed March 30, 1916.

Z '0 all whom it may concern Be it known that I, JAN Knrsnn, of The Hague, Netherlands, have invented certain new and useful Improvements in Cross- Bars for Roller-Curtains; and I do hereby declare the following to be a full, clear, and exact description of the invention, such' as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The here described invention is relating to a cross bar for keeping roller curtains and the like stretched; this bar is to be connected to the curtain and the fringe in such detachable manner that the fringe has no more to be sewn to the curtain while the loop of the latter required until now becomes superfiuous. For this purpose the cross bar is provided at its upper and lower ends with a bore hole and a slot or groove extending from same. These grooves allow the fringe and the curtain of being attached to the cross bar in the manner described in the patent application No. 47,836, 1915.

The invention is shown in a form of execution by the accompanying drawing.

The end 7) of the curtain a is introduced through the slot into the bore hole (Z, then passed around one side 6 (the right side) of the bar 0, introduced through the slot at the lower side of the bar into the bore hole f, passed around the other (left) side 9 of the bar and finally introduced for the second time into the upper groove. The strip h with the fringe 71 is clamped in the lower groove by means of a bar or rod 70 provided with a rib Z this bar clamping also the curtain. A rod m of circular section passed longitudinally through the upper bore hole prevents the curtain from leaving the groove. The arrangement of the curtain at right angles with the cross bar is simplified by providing the bar with a groove a into which the curtain end is introduced before being introduced into the bore hole (Z and passed around the bar. Notwithstanding the described way of attachingithe fringe is to be preferred, the connection may also be realized in any other manner, for eXam-' ple by means of a loop and a rod of circular Copies of this patent may be obtained for five cents each, by addressing the commissioner of latents,

section. Both rods clamp the curtain sufficiently to prevent .it from being drawn out. The shape of the grooves maybe varied within certain limits.
