PETER FBANTZ, OF STERLING, ILLINOIS, ASSIGNOILTO FRAN'IZ MANUFACTURING CO.,- F STERLING, ILLINOIS, A CORPORATION OF ILLINOIS.

TRACK FOR DOOR-HANGERS.

To all whom it may concern:

Be it known that I, PETER FRANTZ, 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 rovide a simple and efiicient structural ormation 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 together in a ready and eifective manner to provide a track of any desired extent, alljas 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 couplin between standard lengths of the track. l ig. 2 is a transverse section on line w w, Fig. 1. view of a modification.

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

Referrin to the drawings, 1 represents portions 0 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 constitute the longitudinal track for the usual tandem wheels of a door hanger, and said vertical web also terminates in an outwardly extending inclined web 7, which is adapted to very eflieiently brace and support the track against ordinary stress in actual use. It is within the province of this part of the pres ent invention to make the inclined bracing web 7 integral with the other webs 3, 4 and Fig. 3 is a similar Specification of Reissued Letters Patent. Rgfssued Dec; 17, 1912.

5, and secure the web 6 thereto as a se arate part, as illustrated in Fig. 2, or to ma e the webs 3, t, 5 and 6 integral, and secure the web 7 thereto as a separate part, as illustrated in Fig. 3.

The 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 fit the outer surface of the same, as shown in Figs. 2 and 3.

8 is a screw passing through the upper end of the coupling band 2, to effect an attachment of the track to the face of a wall or 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 bencath and supports the inclined shed portion or web 4 of the track.' Said bracket is secured to the coupling band 2 in spaced relation corresponding to the thickness of the web 4c, by rivets 10 and interposed washers or collars 11, as shown.

12 is a supporting 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 13 and interposed washers or collars 14. as shown.

With 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 1st, while the web.

6, which constitutes the track surface, prof" inturned vweb extending laterally from tile lower end of said intermediate web, and an outwardly inclined web depending from the,

lower end-of said intermediate vertical web,

substantially as set forth, and a supporting member provided with means for engaging the outer surface of the track, the-inner surface of the said lower inclined'weh, and the bottom of said inturned web.

2. A track comprising in combination a pair oftrack len the each formed with an upper vertical we an inclined Web extending outwardly from the lower end of said.

5. A sheet metal door hanger track comprising track sections disposed end to end, and I supporting member provided with means for removabl said sections, and h bracket secured upon the insideof the lower end portion of said member, with space between for'the thickness of the sheet metal,

and the up er end of said bracket being bent inwar to engage the, bottom of the track;

6. A-sheet metal door hanger track comprising track sections disposed end to end, and a supporting member provided with the track engaging the ends of r spacing the sections nrpart endwise, said means including a said sections, and for spacing the sections apart endwlse, said means including abracket secured upon the inside of the lower end portion of said member, with space between for the thicknesses of the sheet metal,

means for remova-bly engaging the ends of and the upper end of said bracket being bent inward to engage the bottom of the track, together with rivets inserted through the said member and bracket, said rivets having portions which space the member and bracket apart.

7. A sheet metal door hanger track'comprising track sections disposed end to end provided with separated end edges, and a supporting member provided with means for removably engaging the ends of said sections between said end edges, saidsec- -.tions providing a continuous track surface interiorly thereof.
