Thisl invention relates to car doors for railway house cars and more particularly it relates to a track means for supporting said doors for sliding movement. Y

At the present time it is the almost universal practice in steel car and steel door construction to utilize brackets, known as track brackets, connected to the side sill of a steel car, which brackets carry and support the track for sliding steel doors used on such cars. This construction necessitates the use of a large number of castings, usually of malleable iron, which. castings are of uncertain quality and are subject to shrinking, cracking and are expensive. Further, in riveting these brackets to the Side sills of a car a total of six (6) rivets for each bracket is often required, involving consequently a great deal of labor and added expense.

This invention has, for an object. to obviate the expense and labor incident to the use of track brackets for supporting a track.

It is also an object of this invention to introduce a very desirable economy in car door construction by the elimination of the use of track brackets.

It is a further object to reduce the number of parts heretofore employed in steel door construction by dispensing with the track brackets and by securing the track or tracks directly to a part of the steel car.

This invention has. for an object, the drainage of water and proper disposal of other foreign matter which may fall upon .the track.

Referring first to the construction shown inFigures 1 to 3, inclusive, of the drawing, the numeral 10 designates an all steel or metal doorshown in the present embodiment as a bottom :supported door.'A Secured Lby means of rivets 12 adjacent the lower corners of the doorY are hangers 11. A roller 13 iscarried Vby `each of these hangers and is *rotatably mountedjtherein by means of'a pin 14C.'4k Projecting downwardly from each vof the hangers on, the outside of thetrack 16 are extensions 15 which limit the inward Opening movement of the vdoor is limited by Stops 25. The track 16, upon which' the door slides, is positioned' below the floor A24L of the carand iS clearlyy shown. in Figure 3 of the 70 22'without the' intervention of track brackets. .The track may be, and preferably is, formed of rolled steel. Y. The track is provided with ya downwardly extending flangeV 17,l through which rivets 23 extend in fas-1 ,teningthe'track directly to the side sill. Extending horizontally' and forming preferably, though not necessarily, anv integral portion of the track is the flange 18 adapted so byl the door hangers.

It is evident that other foreign substancesfwill also be shed from the track due to the arrangement of the angu- Vlarlvy connecting anges;

To further aid in the proper drainage and disposal of foreign subject matter from the track. filler or spacing plates 21 are employed. These filler plates are interposed between Vtheattaching flange 17 and the side sill 22. which filler plates are positioned at im posal of other matter is permitted.

of the car for a purpose hereinafter referred to. By the use of these filler or spacing plates the track is spaced from the side sill, consequently providing openings between the track, the side sill and adjacent filler or spacing plates, permitting disposal of water and other foreign substances from the track.

To maintain the desired relation between the track, the filler plates and the side sill, the rivets 23 are extended through the members mentioned, there being preferably two rivets used with each fillerplate. The filler plates are so spaced relative to each other that the ordinary spacing used where track supporting brackets are employed', is maintained.v Because of this fact, it is apparent that no additional labor or fabricating of holes in the side sill is required.

Referring to the modification shown in Figures fi andr 5 of the drawing, the track is designated by the reference numeral 2G. The track is preferably formed with an integral secured directly to said sill and having a vertical securing flange, a horizontal flange extending outwardly from said securing flange, said horizontal flange lying below the floor of said car and the lower edge of said door, a vertical flange extending upwardly fromvsaid horizontal ange, the track terminating outwardly of said car in a horizontal tread, said horizontal flange and said last mentioned vertical flange presenting an angle directed toward said sill and lying below the floor of the car, said lower edge of said door being positioned between said last mentioned rvertical fla-nge and the sill of said car.

This Aconstruction is quite similar to that illustrated in Figure 3 of the drawing. It is noted, however, that. the flange 29 shown iin Figure 5 of the drawing is inclined downward-ly relative to theflange 30 for. the purpose of aiding in the disposition of water and other foreign substances.
