CURTAIN DRAWING DEVICE Filed March 18, 1931 ww aim-1 Patented Sept. 20, 1932 UNITED STATES JOHANN PETER SCHMIDT, JR., OF REMSCHEIDvIDORFMUHLE, GERMANY CURTAIN DRAWING DEVICE.

Application filed March 18, 1931, Serial No. 523,449, and in Germany December 2?, 1930. g

This invention relates to a curtain-drawing device and consists in the combination with a flanged supporting rail and with curtain suspending elements adapted to ride on the flange of said rail, of a slide which snugly embraces the rail flange and which is formed with a tongue adapted to enter the suspending elements for collecting the latter on the slide.

The slide may either be composed of a plate which is folded in conformity with the shape of the rail flange or of a wire which is looped and bent to embrace the flange.

For use on curved supporting rails, the slide may be made flexible or composed of pivotally connected links.

Fig. 1 of the accompanying drawing represents a side view of one form of the device, Fig. 2 is a cross section on the line AB of Fig. 1,

Fig. 14 is a bottom view of a device provided with a jointed slide of modified construction,

Fig. 15 is atop view of a device comprising a wire slide,

Fig. 16 is a cross section of Fig. 15, Fig. 17 is a topviewof a device comprising a modified form of wire slide, and

Fig. 18 is a top viewwof adevice comprising a still further modified form of wire slide. The curtain-drawing device comprises a flanged supporting rail 1, a plurality of ourtain suspending elements 4 adapted to ride on the rail flange and for this purpose provided either with integral bearing members 5 or attached'bearing members 6,'and a slide 2 whereon said suspending elements can be collected, the bearing members 5, 6' being rounded off to enable them to move easily from the rail flange on to. the slide. The

slide is operated in the usual manner by means of cords which areconnected to eye-' lets 8. At the forward end of the slide a tongue 3 is provided which is adapted to enter the suspending elements and guide them on to the slide.

In the arrangement shown in Figs. 1 to 7 the slide is made from a thin sheet metal strip which is folded over at the edges for engagement with the flange of a T-rail. The eyelets 8 shown in Figs. 1 and 2 may be replaced by a yoke 80; connected to the underside of the slide as shown in Fig. 7.

Fig. 8 shows a sheet metal slide 2a fitted to an L-shaped supporting rail 1a, and Figs. 9 and 10 show a slide 26 fitted to the lower portion of a rail 1?) of C-shaped cross section.

In Fig. 11, a sheet metal slide 20 is bent so as to fit a T-rail 10 the flange of which is formed with upturned edges, and Fig. 12 shows a slit tubular supporting rail 1d which encloses a forked sheet metal slide 2d which is bent around the edges of the slit.

For use with curved supporting rails, the slide may be made up of pivotally connected links 9 as shown in Fig. 13. A modification of this arrangement is shown in Fig. 14 wherein links 9a are pivoted to a connecting strip 10 which is flexible to allow the slide to pass from a straight rail portion on to a curved one and vice versa. 7

Fig. 15 shows a slide 7 made from a wire which is looped and bent over the rail flange. A similar arrangement is shown in Fig. 17 whlere the wire slide 704 is bent to fit a curved rai Fig. 18 shows a slide comprising two parconnected alternately to opposite springs,

bear against the underside of the rail flange and form controlling elements for the springs. This kind of slide can be used either "for straight or for curved rails.

I claim 1. A curtain-drawing device comprising a flanged supporting rail, curtain suspending elements adapted to ride on the flange of said rail, a slide arranged on the underside of the rail and snugly embracing the rail flange, and a tongue at one end of said slide adapted to enter the suspending elements for collecting the latter 0n the slide.

2. A curtain-drawing device as claimed in claim 1 wherein the slide consists of a plate which is folded in conformity with the rail flange.

3. A curtain-drawing device as claimed in claim 1 wherein the slide comprises awire which is looped and bent to embrace the rail flange.

4. A curtain-drawing device as claimed in claim 1 wherein the slide is composed of pivotally connected links.
