JOHN W. DELLINGER, OF DECATUR, ILLINOIS.

CAR-DOOR.

SPECIFICATION forming part of Letters Patent No. 499,909, dated June 20, 1893.

Application filed December 3, 1892. Serial No. l=53,99'7. (Ne model.)

To all whom it may concern:

Be it known that I, J OHN W. DELLINGER, of Decatur, in the county of Macon and State of Illinois, have invented certain new and useful Improvements in Oar-Doors, of which the following is a specification.

This invention relates to the doors of grain cars. It is intended to provide improved mechanism for fastening such doors closed, for giving them initial opening motion, and for swinging them upward against the top of the car; and it is embodied in the details of construction and combinations of parts hereinafter set forth and claimed. 4

In the drawings forming part of this specification Figure 1 is an elevation of the exterior surface of a door constructed in accordance with my invention. Fig. 2 is an elevation of the interior surface of the same, and Fig. 3 is a section lengthwise of a slide for a swinging guide bar, showing the catch that retains the door in position on the bar when the door and bar are swung upward.

' The door 1 overlaps the inner surfaces of the casing, and its overlapping ends are provided with sliding bearings, or keepers, 2, through which the swinging bars 4: extend. The bars are hinged to the upper part of the casing, as shown at 5, and they have catch blocks 6 at their upper ends, and somewhat similar blocks, 7, at their lower ends, as seen clearly at the left side of Fig. 2, where the upper end of a keeper is broken away to expose the block. Each keeper or slide bearing is provided with a catch as 3,seen in'Figs. 2 and 3, which engage the blocks of the bars and limit the motion of the door on such bars. The door is preferably provided on its inner surface with ahandle as 8. Lock bars 10 and 11 are pivoted at 12 and 13 respectively on the outer surface of the door, and their inner ends extend through link 17, while their outer ends are adapted to engage the recesses 19 in the sides of the door casing. Lever 14 is pivoted at 15, and it has the curved extension 16 which also extends through the link below the ends of the lock bars. Rest blocks 9 are secured to the door casings immediately below the recesses 19, and they support the lock bars when the latter are in the position indicated by dotted lines in Fig. 1. Hook, or

' link, 13 is swung on pivot bolt 13, and it is used to hold the end of lever 14, as shown. When the door is closed the ends of the lock bars engage the recesses of the casing, as seen in solid lines in Fig. 1, and are locked in that position by catching link 18 over the end of handle 14.. When it is desired to open the door, the handle of the lever is released and swung downward as indicated'by dotted lines in Fig. 1, thereby raising the door and drawing the lock bars out of the recesses. This permits the grain to discharge through the opening below the bottom of the partly raised door until the door is relieved from pressure, and then the door is slid upward on the guide bars 4 until catches 3 pass above blocks 6, as indicated in Fig. 3, when the bars and door are swung upward on hinges 5 and suitably secured to the roof of the car. The lock bars hold the door against motion in all directions, and they lift evenly on both sides when the lever is turned down.

The swinging guide bars provide means for raising the door entirely out of .the way, and are themselves swung entirely out of the way by same operation, thus leaving the door opening unobstructed when the car is used for carrying other commodities besides grain.

I claim 7 1. The combination with the door and the casing having lateral recesses, of the lock bars, the link and the curved lever, constructed and arranged substantially as set forth.

2. The combination with the door and the casing having lateral recesses, of the rest blocks on the casings below the recesses, the lock bars, the link, and the curved lever, all constructed and arranged substantially as set forth.

3. The combination with the door and the casing having lateral recesses, of the lock bars, the link, the curved lever, and the catch or link adapted to secure the lever, substantially as set forth.

4:. In grain car doors, the combination of the guide bars hinged at their upper ends, the door mounted slidingly on the bars, the casing having lateral recesses, the lock bars, the link, and the curved lever, substantially as set forth. i

In testimony whereof I sign my name in the presence of two subscribing witnesses.

JOHN W. DELLINGER.
