T all whom it may concern Be it known that I, HENRY RHoBEoKER,

a citizen of the United States of America,

residing at Columbus, in the county of Franklin and State of Ohio, have invented new and useful Improvements in Car Doors, of which the following is a specification.

The object of the invention is. to provide a simple, efiicient and. durable freight car door which is protected against attack from the outside by levers or tools designed to force the same from its mountings to give surreptitious access to the car, which is adapted to prevent the escape of goods even of the granular form from the interior of the car, which is adapted to be locked against entrance at one side from the interior of the car so that but one sealing or sealed lock is required, and to provide a door mounting whereby the opening .and closing movement thereof when released is facilitated and whereby damage to the door by contact with exterior objects adjacent to the car is eliminated to insure full closure of the structure; and with these objects in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the accompanying drawings, wherein Figure 1 is a side view of a car having a door construction embodying the invention.

Figure 2 is a horizontal section of the same showing one of the doors interiorly and the other exteriorly locked.

Figure 3 is a vertical section on the plane indicated by the line 3-3 of Figure 2.

Figure 4 is a detail view of the interior lock.

Figure 5 is a vertical interior lock Figure 6 is a detail view of the interior look bolt.

Figure 7 is a similar iock shackle.

The door 10 is mounted for horizontal sliding movement between the car wall 11 and a guide 12 whereby it is housed andrprotested when in an open posit on, the lower edge of the door extending through a slot 14. of the car and resting upon hearing rollers 15 extended transversely hetween and mounted in angle bars 16 and 17 which marginally'proteet the guide slot and sustain the wear incident to the sliding movement of the door. The upper edge'of the door is mounted in suitable channeled sectional view of the view of the exterior guide 18 also preferably of metal which is extended to form a protection 19 for the upper wall of the door opening just as the horizontal flange 16 of the angle bar 16 constitutes a sill plate to protect the lower wall of thedoor openin The door is adapted in its closed position I to be received by a keeper; 20 arranged vertically at the inside of the vertical wall of the door opening adjacent to the free edge of the door, and the latter overlaps the jamb or wall of the door opening as indicated in Figure 2. The door carries a stop flange 21 for abutting engagement with the wall or jamb of the door opening at the free edge of the door when the door is in the closed postion and in this stop flange is provided an opening for the' reception of a staple 23 vwith which is engaged the looped shackle 24 held to the frame of the door by means of retaining chain 25 and provided with the usual slots 26 in the arms thereof for the reception of the sealing strip or band 27.

Where the car as in the construction illustrated is provided with a door at each side, each door is preferably provided with an exterior fastening means such as above descr'bed including the stop flange, staple and shackle, and in addition thereto each door is provided with an interior fastening device indicated at 28 and consisting of a bolt 29 extending through a seating block 30 on the frame of the car to span the guide in which the door operates in the path of the adjacent or rear edge of the door to obstruct and prevent the movement thereof, the terminal ofsaidbolt being engaged with a socket 30' in the wall of the car. This bolt is held in place against loss or removal by a suitable retaining chain 33 and is adapted to be secured in its door engaging position by a locking pin 32 also having a retaining chain 31. I

Thus when it is desired to load the car it is preferable to secure one of the doors at the inside so as to avoid the necessity oi sealing both doors exterior-1y; and after the car has been loaded the other door may be locked by means of the exterior means above described, and sealed-to atl ord tection in the event that the door should he surreptitiously opened. The arrangement of the doors at the inner surfaces of the walls of the ear protects them from contact with adjacent objects and from being opened by prying them ioose nee means of de what is car wall and having upper and lower guides for the corresponding edges thereof and a housing guide extending from the rear edge thereof and parallel with the side wall of the car for the recept'on of the door when open, the door being adapted at its free or front edge to overlap the inner surface of the door jamb or frame in its closed position, a guide clip disposed to receive the overlapping portion of said edge, and an outwardly extending stop flange being provded adjacent to the free or front edge of the door and extending the full height thereof for abutting contact with the inner surface of the door jamb or frame.

2. A car door mounted for horizontal sliding movement at the inner surface of the car wall and having upper and lower guides for the corresponding edges thereof and a housing guide extending from the rear edge thereof and parallel with the side wall of the car for the reception of the door when open, an interior lockin means bein provided for the rear edge 0 the door an consisting of a bolt for spanning said housing guide in the path of the door, and means for securing said bolt in its operative position.

3. A 'car door mounted for horizontal sliding movement at the inner surface of the car wall and having upper and lower guides for the corresponding edges thereof and a housing guide extending from the rear edge of the door and parallel with the side wall of the car for the reception of the door when open, and an interior locking means provided at the rear edge of the door and consisting of a seating block mounted on the inner face of the housin guide, a bolt passing transversely throug the seating block and adapted to span the space between the housing guide and the car wall adjacent the rear edge of the door when closed, and a pin removably engaged with an axial bore in the seating block and passing transversely through a registering hole in the bolt when the latter is in spanning relation with the door edge.

In testimony whereof he afiixes his signature.

HENRY RHOBECKER.
