TRACK FOR DOOR-HANGERS.

Specification of Letters Patent.

REISSD Patented May 23, 1911.

To all whom it may concern:

Be it known that I, PETER FnnN'rz, a citizen of the United States of America, and a resident of Sterling, in the county of Whiteside and State of Illinois, have invented certain new and useful Improvements in Tracks for Door-Hangers, of which the following is a specification.

This invention relates to that type of overhead tracks for sliding doors, in which an extended horizontal wrought metal shell having an inturned or lateral flange at its lower edge provides a track for the usual tandem wheels of the hanger. And the present improvement has for its object to provide a simple and efficient structural formation and combination of parts whereby strength to resist flexure of the track with lightness and economy of material is attained, and with which standard lengths of the track can be coupled togetherin a ready and effective manner to provide a track of any desired extent, all as will hereinafter more fully appear.

In the accompanying drawings :-Figure 1, is a detail front elevation of a track embodying the present invention, and illustrating the coup ing between standard lengths of the track. Fig. 2, is a transverse section on line sc-a', Fig. l. Fig. 3, is a similar view of a modification.

Similar numerals of reference indicate like parts in the different views.

Referring to the drawings, 1 represents portions of two adjoining lengths of the track coupled together by a coupling band or member 2 hereinafter described in detail. In the present construction each length of track comprises an upper vertical attaching web 3, from the lower end of which extends outwardly an inclined shed portion or web 4, and from the outer end of said shed depends a vertical web 5, the lower end of which terminates in an inturned and preferably trough shaped web 6 which constitutes the longitudinal track for the usual tandem wheels of a door hanger, and said vertical web 5 also terminates in an outwardly extendin inclined web 7, which is adapted to very e ciently brace and support the track against ordinary stress in actual use. It is within the province of this part of the present invention to make the inclined bracin(r web 7 integral with the other webs 3, 4 an( 5, and secure the web 6 thereto as a separate part, as illustrated in Fig. 2 or to make the webs, 3, 4, 5 and 6 integral, and secure the web 7 thereto as a separate part, as illustrated in Fig. 3.

'Ihe coupling band 2 above referred to is formed from a flat bar of metal bent to the outer contour of the webs 3, 4, 5 and 7 above described, and adapted to closely lit the outer surface of the same, as shown in Figs. 2 and 3.

8 is a screw passino' through the upper end of the coupling ban 2, to effect an attachment of the track to the face of a wall o1' the like.

9 is an angle bracket arranged in the interior of the track and provided with a vertical member adapted to bear against the wall, and an inclined top member that rests beneath and sup orts the inclined shed portion or web 4 of the track. Said bracket is secured toV the coupling band 2 in spaced relation corresponding to the thickness of the web 4, by rivet-s 10 and interposed washers or collars 1l, as shown.

12 is a support-ing bracket arranged underneath the track and formed with an inclined upper arm which rests beneath and supports the web 6, and with a lower inclined arm that is secured to an adjacent portion of the coupling band 2, in spaced relation corresponding to the thickness of the web 7 by rivets 1B and interposed washers or collars 14 as shown.

Vith the described arrangement of the coupling band 2, and brackets 9 and 12, sockets are provided for the reception of the adjoining ends of track lengths, and in my preferred construction, as shown in Fig. 1, the webs 3, 4, 5 and 7 are separated a distance equal to the diameter of the attaching screw 8, or Washers 11 and 14, while the web 6, which constitutes the track surface, projects beyond the otherwebs to abut against the next adjacent web 6, and provide a continuous track surface.

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

1. A track member formed with an upper vertical web, an inclined web extending outwardly from the lower end of said vertical web, an intermediate vertical web depending from the outer end of said inclined web, an inturned web extending laterally from the lower end of said intermediate web, and an mediate Vertical web, acoupling band formed to lit the exterior of the track l5l lengths, and supporting brackets Secured in separated relation to said coupling band to form receiving sockets for the end of the track lengths, substantially as set forth.

Signed at Chicago, Illinois this 11th day 20 of January 1911.
