RAILWAY CAR SIDE DOOR Filed Aug. 2, 1928 4 Sheets-Sheet 4 Patented Sept. 16, 1930 fuaireu sTATns PATENT OFFICE GEORGE E. GOUTANT, OF DECATUR, ILLINOIS RAILWAY- CAR SIDE DOOR Application filed August 2, 1928. Serial No. 296,943.

device relates to a railway car having a door opening in its side wall and a door arranged to move horizontally to close the door opening. Such a door may be supported upon the side sill by brackets with anti-friction rollers mounted therein, (as illustrated) or it may be supported by suspension hangers engaging a track supported 'byfthe side plates adjacent the top of the door opening. The front vertical edge of the door is provided with a stiffener or frame member having a tongueor extension which engages a front door stop mounted on the front door post and the rear vertical edge of the door is provided with a stiffener or frame member having a tongue or extension which engages a rear locking strip mounted on the rear door post. These front and rear tongue engagements form weatherproof and burglar-proof joints. The upper horizontal edge of the door is provided with a stiffener, frame member or a top interlocking strip and the bottom edge is provided with a frame member of perhaps a bottom track with a vertical depending lip behind the supporting bracket (as illustrated).

The front, rear, top and bottom stiifeners may be secured together at the corners of the door to form a rectangular frame. It is common practice tostifl'en the four sides of a wooden door with such frame members and to stiffen the wooden door with battens, stiles and intermediate horizontal metal stiffening strips, but 'my device is an improvement thereon and contemplates the use of a rela tively thin metallic plate rigidly secured to such a frame (or formed integral therewith) and'may be reinforced with integral horizon tal, vertical or diagonal corrugations or embossments formed therein which transmit any loads or thrusts imposed thereon to the frame members. A side door is subjected to tion is caused by the door opening being out of square. Such forces are also caused when the door suddenly hits the back door stop an eccentric blow. The crow-bar when used to open a door is another source of trouble.

Considerable difiiculty is experienced by the shearing of the rivets which secure the metallic plate to the frame members or stiffeners. This is caused by the rivet heads hitting the frame members of the car when being moved horizontally to open or closed position. It is not unusual for a rivet head to come in contact with a door post, whereupon the hasp is put over the staple and hit with a sledge, causing a sheared rivet or broken hasp. Countersunk rivets in such a thin metallic sheet are impracticable. (Such sheets aer usually thick.)

The object of the invention is to provide a door for a railway freight car made of a thin metallic sheet, having stiffening members riveted to one or more margins thereof. and to oil'set said margin or margins so that the heads of the rivets will be within the plane bounding the main body of the door so that such rivet heads will clear the car body when moving to open or closed position; or in other words, the main body of the door sheet will prevent the rivet heads from striking the car body.

Another object is to protect the front or back spark strip by positioning it adjacent the vertical door stifiener (or securing it thereto) so that any blow upon the spark strip will be partially transmitted to the stiffener.

Figs. 1, 2, 3 and 4 show sections through front, back, top and bottom, respectively, of my preferred construction.

Figs. 5, 6, 7 and 8 show a modified construction.
