TRACK FOR DOOR-HANGERS.

Specification of Letters Patent.

Patented Aug. 1s, 190s.

Original application led March 4, 1907, Serial No. 360,344. Divided and this application filed March 2, 1908. Serial No. 418,639.

To all whom it may concern:

Be it known that I, SAMUEL W. BEEsoN, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Tracks for Door-Hangers, of

which the following is a specification.

This invention relates to a track which is more particularly designed for supporting door hangers of boX freight cars, but the same may also be used for other purposes.

The object of this invention is to produce a track for this purpose which is simple and durable in construction, which will reliably support the hanger and the door suspended by the same, which can be produced and maintained at comparatively small cost and which is not liable to become deranged and rendered inoperative by the jarring or straining of the car.

This application is a subdivision of an application for atent filed by myself March 4, 1907, Serial o. 360,344, and patented-April 8,1908,N0.s33,775.

In the accompanying drawings: Figure l is a fragmentary perspective view of a box freight car having its door suspended from my im roved track. Fig. 2 is a fragmentary vertica transverse section taken in line 2 2, Fig. 3. Fig. 3 is a fragmentary longitudinal section in numbered line 3 3, in Fig. 2.

Similar letters of reference indicate corresponding parts throughout the several views.

Those parts of the car or other structure which receive my im roved track are preferably constructed as ollowsz-A represents a supporting beam secured lengthwise and horizontally on the outer side of the side plate B by means of a plurality of horizontal bolts l) passing transversely through these parts at intervals. On the underside of this supporting beam the same is provided with a longitudinal groove or seat c which is semi-circular or nearly so in cross section. In this groove is seated the upper side or half of a longitudinal tubular guide, way or track D which is rovided on its underside with a longitudina slot d. This tubular track or guide is iirmly secured in the groove of the supporting beam by means of a plurality of vertical bolts e passing through the upper portions of the track and the su porting beam and each bearing with the hea at its lower end against the bore or inner side of the track while its nut bears against the upper side of the supporting beam and is prevented from becoming oose by means of a cotter pin, as shown in Figs. 2 and 3,or any other suitable means.

The horizontal bolts which connect the supporting beam with the plate B and the vertical bolts which connect the tubular track with the supporting beam are preferably so dis osed that each horizontal bolt b is arranged c ose to one of the vertical bolts e, as shown, so that a firm connection is made between the beam and plate immediately at the oint where the vertical bolts connect the eam with the track, thereby reliably connecting the track with the car body and effectually securing against warping or displacement of the same under the jars or other destructive action to which the car is subjected. The suspending device whereby the door is slidingly supported from said tubular guide or track consists preferably of two hangers or shoes F. Each of these hangers consists of an upper enlargement, head or runner f which 1s adapted to slide lengthwise in the bore of the tubular track, a reduced portion or neck g projecting downwardly from the underside of the head through the slot in the bottom of the track, and a socket h which is arranged at the lower end of said neck and in which the upper edge of the adjacent ortion of the door 1s secured by means of bo ts i or otherwise. The upper side of the head is concaved or recessed lengthwise so as to form a clearance space for avoiding interference with the heads of the vertical bolts e which are arranged in the upper part of the track.

Inasmuch as the tubular track is confined on opposite longitudinal sides by the walls of the groove of the supporting beam the metal of the track on opposite sides of its slot is held against spreading under the downward pull of the hanger, thereby always retaining the guiding and supporting devices of the door in their operative condition. The inner wall of the groove of the supporting beam is confined between the tubular track and the adjacent plate of the car body, whereby this wall is positively held against displacement. In order to also guard against any possibility of the outer wall of said su porting beam from becoming displaced a plhrality of clips are'provided each of which consists of a vertical body plate K secured tothe outer side of the sup- Aporting beam by one of the horizontal bolts b and a lip Z projecting inwardly from the lower porting beam in the manner described, the

same is held perfectly straight at all times and prevented from becoming accidentally bent, thereby insuring a smooth surface Jfor the supporting'shoe or hanger to run on and enabling the door to be easily opened and closed at all times. The lower edge of the door is prevented from swinging outwardly away from the car body by the usual door track brackets m, but if these should be accildentally knocked ol, the door would still be prevented from swinging outwardly by engagement of the outer sides of the necks of the hangers with the stationary edge of the tubular track, thereby avoiding interference and damage by collision of the door with other cars or obstructions which would be liable to occur if the tubular track were not held rigidly in position.

I claim as my invention:

1. rlhe combination oi' a horizontally disposed tubular track of circular cross section having a longitudinal slot in its underside, with a longitudinal supporting beam provided on its underside with a longitudinal groove of semi-circular cross section in which the upper' half of said track its snugly, whereby the lower parts of the track on opposite sides of its slot are sustained against spreading under the weight of a door hanger resting thereon, means for connecting the top of the track with the beam, and means 'for connecting the beam with a support.

2. The combination with an upright support and a horizontally disposed beam having a groove in its under side, bolts connecting said beam and support, A of a horizontally Ydisposed tubular track having a longitudinal slot in its under side and adapted to be seated inisaid groove, bolts connecting said track and beam, and clips each having a vertical body which is secured to the outerside of said beam by one of said horizontal bolts and a lip arranged on said body and `engaging with the adjacent lower edge of said beam, substantially as set forth.
