- To all whom it my concern:

Be it. known that I, flunris L. SMITH, a citizen of the United States, residing at Dunn, in the county of Benton and State of Indiana, have invented certain new and 'useful Im rovements in Grain-Car Doors, of which t is following is a s eciiication.

This invention coinpre ends certain new and useful improvements in doors for grain cars, and the invention has for its object the simple, durable and ellicient construction of a door adapted to slide sidewise across and away from a door-way and embodying a hinged upper section adapted to,be swung inwardly and secured in a suspended condition to the top or root of the car when not desired for use, and the invention consists in certain cons tructionsand arrangements of the parts that lshall hereinafterv fully de scribe and claim.

For a full understanding of the invention, reference is to be had to the following de scription and accompanying drawings in which:

' Figure 1 is an elevation of a car-door con 'structcd in accordance with my invention;

Fig. Zis a horizontal sectional view thereof;

Fig. 3 is a transverse vertical section; Fig. 4

door posts or j ambs' defining the side walls of the door-way. i

3 designates the upper doonsill of the car, and 4 designates a rail which is secured to saidsill and which extends across the door way and to one side thereof as clearly illusbrat-ed in the drawings.

()utwardly facing hooks 5 that are formed on the. upper ends of suspension bars 6', are

engaged withthe rail 4 and are adaptedto slide thereon, said suspension bars being nv .eted, bolted or otherwise fastened to the main or lower door section 7 at the upper edge thereof, so as to sup ort the door as ii; is

. slid across and to one si e of the door-way. 1'lhedoor 7 is preferably reinforced by trans ycrsoly exten.

opened.

mg steel bars 8 r ivetedthereto. The lower edge of the door 7 is adapted to slide in a groove or channel in thelowcr supporting rail 9.

One edge of the door 7 is formed with an angularly disposed edge 10 which is adapted to scrape against the side wall of the car when the door is moved to an open position so asto prevent any leakage of grain around the side edge of the door, and also to niaintain a secure joint between such side edge and the wall of the closed position.

The door section 7, as is common with. all

car when the door is in a doors of this type, terminates at its upper edge below the upper edge of the door way and'is supplemented by an upper door section which in the present instance is designated -11 and which is secured near its ends to hangers 12 riveted or otherwise fastened thereto. The hangers 12- cXtendu'owardly and are curved as indicated at 13 and extend around and clear of the rail 4 and the upper ends of the hangers 12 are pivotally connected to the brackets 14 secured to the wall 3, so that the upper door section 11 may be closed in the door-way above the upper edge of the main doorL and be swung backwardly and upwardly out of the way and held in an inoperative position against the roof of the car by any desired fastening device (not shown). The upper section ll of the door is grooved near its ends as indicated at 15, the grooves ext-ending vertically and being designed to en-age the suspension bars 6 of the main or ower door? when the upper section '11 is closed, in order to admit of a close joint between the two sections. 7

l6 designates a supplemental door which is mounted in the main door 7 near the lower end tllereof and which is ,adapted to slide in channel irons 17 secured to the main door so as .to open or close anopcniug there in, in order to permit the grain to flow out whenever desired before the main door 7 is It is to be understood that this small supplemental door-'16 is provided with any form of handle so that it may be opened or closed from the outside of the car.

In order to'hold the main door in closed position I have provided latches 18 that are mounted within casin s in the door jarnbs and that are former with hooked ends adapted to be inserted through horizontally elon ated slots 19 formed in the main. door,-

the atohes being turned after their hook-e;

have been inserted through the slots so that thereto above the door, of suspension bars Way, and hangers secured to said upper door the hooks will engage with the rear face of the door and hold the same locked. In order to cover these slots 19 to prevent the grain from leaking out, I have provided caps 20, to be fastened by rivets or the like to the inner face of the door over the slots 'as shown. In order to hold the upper section 11 of the door in closed position I have provided the turn-buttons 21.

Having thus described the invention, What is claimed as new is:

1.,The combination of a car, rovided with a door-Way, and an elevated rai secured nlountedto move in a side-Wise direction on said rail, a main lower door secured to said suspension bars, an upper door section adapted to close the-upper end of the doorsection and pivotally connected to the car above the door Way and arranged to swing transversely of the door-Way, said hanger rods being formed with bent out portions extending around the rail.

2. The combination with a car rovided with a door-way and an elevated rai secured thereto above the door-way, of suspension bars mounted to move in a sidewise dlreetion on said rail, a main lower door secured to said suspension bars, and an upper door section adapted to close the upper end of the door-way, and hangers secured to said npper door section and pivotally connected to the car above the door-way and arranged to swing in a vertical plane, said upper door section being formed with grooves adapted to receive the sus ension bars.
