Application August 18, 1944, Serial No. 550,099 2 Claims. (01. 16——87.2) 1 This invention relates to new and useful im provements in curtain hangers. More specifically, the invention proposes the construction of a curtain hanger characterized 2 hung from the link 2!. The curtain will be hung from the split rings in any suitable desired man ner. The link and ring may be made of cad mium plated brass. A retainer 24 for the wheels is provided. The by a rail along which run a plurality of curtain retainer has a bottom wall 25 extending across traverse wheel devices. the bottom of the track It and two side walls 26. Still further, it is proposed to provide a curtain Each side wall is triangular in shape with its base hanger as aforesaid having a retainer for the at the bottom and a triangular opening 21 is pro wheels of each device. Another object is to provide a retainer as afore~ 10 vided in each side wall. The bottom wall 25 is also recessed adjacent the bottom of each open said having a stop for a depending hanger. ing 21, the recesses being indicated by the nu For further comprehension of the invention, meral 28 and being best shown in Fig. 6. A trans and of the objects and advantages thereof, ref verse flange 29 extends inwardly from each side erence 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. of each side wall to the web 15. These ?anges act as guards preventing threads from the cur tains from getting caught and wound around the wheels and portions 22, and prevent the retainer from falling off of the wheels, the space between terial part of this disclosure: Fig. 1 is a perspective view of the curtain 20 the flanges and the bottom of the retainer form ing guides for the tracks. hanger of the present invention, only a portion In the accompanying drawing forming a ma 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 of one of the 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 struc ture 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 ori?ces 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 de vices supporting the curtain at intervals. As thus supported, the curtain may be pulled back and forth to open and close an opening respec tively. 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. 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 thick ness 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 re cesses 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 pre ferred embodiments of my invention, it is to be _ understood that I do not limit myself to the pre cise constructions herein disclosed and the right is reserved to all changes and modi?cations com ing within the scope of the invention as de?ned 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 hav ing a bottom wall for extending under and against the bottom ?ange of an I-shaped overhead track and side walls for extending upwards past the sides of said bottom flange and transverse ?anges extending inwardly from each side of said side walls, a pair of wheels for riding on the side por tions of said bottom flange and having axial bores and having their outer faces adjacent the central bore 20. inner faces of said side walls and having the sides A yoke-shaped link 2 l ‘depends from the wheels, of their peripheries adjacent said transverse the link having a horizontal end portion 22 dis ?anges, said side walls having openings with posed in the bore 20 of each wheel. Thus the shoulders, and a yoke-shaped link having its link surrounds the track l6. A split ring 23 is 55 Each wheel has a bevelled inner edge It and a . 3 2,405,020 4 ends engaging into said bores and having its arms extending through said openings and swingingly limited by said shoulders. 2. A hanger, comprising a wheel retainer hav and having their outer faces adjacent the inner faces of said side walls and having the sides of their peripheries adjacent said transverse ?anges, said side walls having openings with shoulders, ing a bottom wall for extending under and against 5 and a yoke-shaped link having its ends engag the bottom ?ange of an I-shaped overhead track ing into said bores and having its arms extending and side walls for extending upwards past the sides of said bottom ?ange and transverse ?anges extending inwardly from each side of said side walls, a pair of wheels for riding on the side por tions of said bottom ?ange and having axial bores through said openings and swingingly limited by said shoulders, said side walls and their openings being triangularly shaped. 10 THEODORE DIERKING.
