DOOR-HANGER.

' Specification of Letters Qatent. Patentd $30, 1909.

Application and October 5, 1907. Serial in). 396,080.

To all whom it may concern:

Be it known that I, WILLIAM D. THOMP- soN, a citizen of the United States of America, residing at Detroit, in the county of IVayne and State of Michigan, have invented certain new and useful Improvements in Door-Hangers, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to a combined door hanger and track especially designed for use in connection with freight cars, and consists in the novel construction thereof and in the peculiar arran ement and combination of parts as more 'ully hereinafter set forth.

In the drawings,-Figure 1 is a vertical cross section through an embodiment of my invention; Fig. 2' is a view in side elevation thereof; Fig. 3 is a perspective view'of the end of the housing and Fig. 4 is a section through line a"w Fig. 1.

The reference-letter A designatesa freight car of ordinary construction, having the usual door opening B formed in its side.

C designates the sliding door for the opening, D the track upon which the door travels,

and E hangers secured to the door carrying suitable rollers engaging the track.

The hangers described are preferably in the form of castings, each comprising a retaining section a bolted upon the inside of the door near its top edge, an upwardly and outwardly inclined bracket arm b carrying a roller 0, a transverse section cl extending across the door top, and preferably set in so that its top will be flush with the top edge of the door, and carrying trough-shaped sections 6, the function of which will be hereinafter set forth.

My improved track and guard 1 form preferably from a single bar of iron rolled to form a vertical supporting section F extending longitudinally of the car above-the 'door, and adapted to be bolted at its upper edge to a strip F on the car side; a transverse inwardly-extending section forming the track proper,indicated by the reference-letter D,-and a depending section G extending downwardly in alinement with the supporting -section F below the track and door top, and covering the top joint.

The track described is of a length to slightly exceed twice the width of the door, so as to permit its being fully opened. The strip F to which the bar forming-the track This, however, isnot essential, and a zeris secured is of a corresponding length, and projects at some distance from the car side, forming in connection with the track a housing in which the hangers travel. The ends of the housing are closed by end-blocks F which prevent the beating in of the rain or snow.

The trough-shaped sections e uponnthe hangers receive and frictionally engage with the depending guard section, the verticallyprojecting portions or lips E constituting wear-plates or irons, and the frictional engagement between the parts servin to prevent the door from sliding to and fro when unlocked due to the motion of the car.

While I have shown the preferred form of track and guard, I do not desire Ito be limited to the same, although on account of its simplicity and convenience of construction I deem the same preferable in use. 1

I have also shown the track proper, as inclined downwardly for the purpose 0 cansing the door upon its travel to and r0 to move inwardly for'the purpose of 0 using a frictional engagement between the wearirons and the guard before referred to.

fectly horizontal track may be e:nploye if desired.

What I claim as my invention is:

1. The combination with a car having a door opening formed therein, of a door therefor, a track above the door extending longitudinally of the car and provided with a guard flange, and hangers upon the door carrying rollers engaging the track, each hangercomprising a casting consisting of a vertical retaining section secured to the inner side of the door near its top, a roller-' section upon the outer side of the door adapted to receive and engage the guard flange.

2. The combination with a car having a door opening, of a door therefor, a combined track and guard for the door consisting of asin le-piece bar fashioned to form a downward y extending supporting section spaced from and secured to the car above the door. an inwardly extending section forming the track proper, and a depending section extending outside of and below the upper edge of the door, and hanger mechanism upon the door engaging the track section.

per edge of the door, and a wear member upon the door engaging the outer face of the housing.

In testimony whereof I aifix my signature in presence of two witnesses.

WILLIAM D. THOMPSON.
