July 30, 1946. T. DIERKENG CURTAIN TRAVERSE WHEEL Filed Aug. 18, 1944 INVENTOR. Ffieo$re $58?" Patented July 30, 1946 UNITED STATES PATENT OFFICE CURTAIN TRAVERSE WHEEL Theodore Dierking, New York, N. Y. Application August 18, 1944, Serial No. 550,099

2 Claims. 1

This invention relates to new and useful improvements in curtain hangers.

More specifically, the invention proposes the construction of a curtain hanger characterized by a rail along which run a plurality of curtain traverse wheel devices.

Still further, it is proposed to provide a curtain hanger as aforesaid having a retainer for the wheels of each device.

Another object is to provide a retainer as aforesaid having a stop for a depending hanger.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a ma terial part of this disclosure:

Fig. 1 is a perspective view of the curtain hanger of the present invention, only a portion of the rail and one device being shown.

Fig. 2 is an enlarged transverse section of the rail.

Fig. 3 is an inverted plan view of the structure of Fig. 2.

Fig. 4 is an. enlarged side view devices of the hanger.

Fig. 5 is a front View of the device of Fig. 4.

Fig. 6 is an inverted plan view of the structure of Fig. l, the link being shown in section.

The curtain hanger mechanism, according to this invention, comprises an I-beam rail ID, the top web ll of which is wider at one side than at the other, this wide side l2 having orifices l3 for screws l4 (only one being shown) which secure the rail to a ceiling or other structure (not shown). The rail may be made of aluminum. It also has a vertical web l5 and a bottom horizontal track It extending on opposite sides of the web 15.

A curtain traverse wheel device i1 is mounted on the rail. There will be a number of these devices supporting the curtain at intervals. As thus supported, the curtain may be pulled back and forth to open and close an opening respectively. Other articles similar to curtains may also be supported from the devices.

Each device I! includes two spaced wheels i8 sliding on track l6, one on each side of web id.

of one of the Each wheel has a bevelled inner edge It and a central bore 20.

A yoke-shaped link 2 l depends from the wheels, the link having a horizontal end portion 22 disposed in the bore 20 of each wheel. Thus the link surrounds the track l6. A split ring 23 is 2 hung from the link 2!. The curtain will be hung from the split rings in any suitable desired manner. The link and ring may be made of cadmium plated brass.

A retainer 24 for the wheels is provided. The retainer has a bottom wall 25 extending across the bottom of the track It and two side walls 26. Each side wall is triangular in shape with its base at the bottom and a triangular opening 21 is provided in each side wall. The bottom wall 25 is also recessed adjacent the bottom of each opening 21, the recesses being indicated by the numeral 28 and being best shown in Fig. 6. A transverse flange 29 extends inwardly from each side of each side wall to the web 15. These flanges act as guards preventing threads from the curtains from getting caught and wound around the wheels and portions 22, and prevent the retainer from falling off of the wheels, the space between the flanges and the bottom of the retainer forming guides for the tracks.

Retainer 24 serves to retain the wheels on the track, acting as a cage for the wheels, the wheels being separated only slightly more than the thickness of web [5 which is thinner than the web H or track It. Furthermore, the retainer provides four shoulders 30, one at each corner of the recesses 28, these shoulders acting "as abutments limiting the swing of the link 2| so that it is not jammed against the sides of the track when the curtain is pulled obliquely at too great an angle when moving it.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

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

1. A hanger, comprising a wheel retainer having a bottom wall for extending under and against the bottom flange of an I-shaped overhead track and side walls for extending upwards past the sides of said bottom flange and transverse flanges extending inwardly from each side of said side walls, a pair of wheels for riding on the side portions of said bottom flange and having axial bores and having their outer faces adjacent the inner faces of said side walls and having the sides of their peripheries adjacent said transverse flanges, said side walls having openings with shoulders, and a yoke-shaped link having its and having their outer faces adjacent the inner faces of said side walls and having the sides of their peripheries adjacent said transverse flanges, said side walls having openings with shoulders, and a yoke-shaped link having its ends engaging into said bores and having its arms extending through said openings and swingingly limited by said shoulders, said side walls and their openings being triangularly shaped.
