SPECIFIGATION forming part of Letters Patent No. 746,400, dated December 8, 1903.

Application nea september 1219013. serial N0.173,o13. (No model.)

To all whom it may concern:

Be it known that I, ANDREW G. STEINBREN- NER, a citizen of the United States, residing in the city of St.`Louis, in the State of Missonri, have`invented certain newand useful Improvements in Grain-Car Doors, of which the following is a full, clear, and exact description, reference beinghad to the accompanying drawings, forming part of this specification.

My invention relates to an improvement in doors for grain-cars, and has for its object the productionof a door that may be the most easily swung upwardly to the roof of the car in which it is positioned when the doorway is open and lowered from its elevated position to again close the doorway. v

The invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a front elevation of my grain-car door. Fig. II is a vertical section through the door. Fig. III is a rear or inside elevation of the door. Fig. IV is an edge view of the door, partly broken out. Fig. Visa section of one corner of the door shown connected to one of the upper hanger-brackets from which the door-supporting rods are suspended. Fig. VI is a horizontal section taken on line VI VI, Fig. III. Fig. VII is a horizontal section taken on line VII VII, Fig. IV. Fig. VIII is a perspective viewof one of the corner-hooks carried by the door. Fig. IX is a horizontal section taken Vthrough one of the securing-bolts ofthe door.

1 designates the posts of a grain-car doorway, and 2 the roof of the car.

3 designates the car-door, which is positioned against the inside faces of the posts 1, and 4t is an apronsurmounting the door 3 and connected thereto by hinges 5 to provide-for its being folded downwardly in the direction indicated by dotted lines in Fig. II, so 'that it will lie against the inside face of the door when the car is empty and the door is to he elevated away from the doorway it controls. The apron is when surmounting the door upheld by catch-hooks 6, that are pivoted to the door-posts 1.

7 is a swinging catch mounted'on the door 3 and adaptedvto be swung into engagement I with the apron -Lwhen saidV apron is folded thereto. i

Sdesignates bolt-boxes fixed to the door 3 and containing slide-bolts 9, by which said door may beheld to the door-posts. When it is in position to close the doorway,these slide-bolts are adapted to enter keepers 10, (see Fig. IX,) fitted to the door-posts in alinement with the locations of the slide-bolts.

In the door 3 are discharge-apertures 11, which are controlled by shutters 12, that ride in guides 13. These openings and shutters do not form any part of my present improvement, and no invention is herein claimed for them.

14 designates strips secured to the ends of the door 3, near the top thereof, and provided with pivot-studs 15. A

l'designates hanger-brackets :secured to the upper ends of the door-posts 1l and bearing-studs 17 projecting from their inner side faces. Within these hangerbrackets are transverse pivots 18. 19 designates swinging rods having elongated eyes 20 at their upper ends that are fitted to the pivots 18 of the hanger-brackets 16 and having at their lowerY ends eyes 21, that are fitted vto `the pivot-studs 15 of the strips 14.

22 designates hooks secured to the door 3 at its lower corners, the said hooks being preferably set into the door, as seen in Fig. IV.

In the practical use of my door it is readily disposed of by swinging it to the roof of the car after the car has been partially emptied and upheld in such position by a suitable supporting-catch 23. (See Fig. II.) When the door is to be swung into elevated position, as mentioned, the apron 4 is first released from its supportingcatches 6 and folded downwardly onto the door. tire door is then swung upwardly, as shown by the short dotted lines, Fig. II, it being pivotally supported and moved on the pivotstems 15, which are mounted in the lower eyes 21 of the swinging rods 19. When the movement of the door, as stated, has been accomplished, the door is in inverted position and occupies the upper part of the doorway only. On the door being inverted the cor- The enner-hooks 22at the bottom of the door, which are at such time elevated to the hanger-brackets 16, are slipped onto the studs 17 of said hanger-brackets, so that the door will be swingingly supported in its inverted position. The top of the door, which is then lowermost, is next grasped and is swung on the studs 17 and elevated vto the roof of the car, as seen by dotted lines, Fig. II, `Where the door is upheld by the lvupportingcatch 23. As the door is raised to the roof of the car the swingrods 19 travel therewith owing to their connection to the strip 14 and its Vpivot-studs, and said rods therefore remain connected to the door ready to serve as supports for the door when it is next lowered for service as before.

I claim as my invention- 1. In a grain-car door, the combination with the door and door-posts, of hangers fixed to said posts, swing-rods forming connection between said hangers and said door, and means carried vby said door to engage with said hangers when the door is inverted and its lower end israised to said hangers, substantially as set forth.

2. In a grain-car door, the combination with a door and door-posts, of hangers secured to said posts, studs projecting from said hangers, swing-rods forming connection between said hangers and said door, and hooks located at the bottom of said door for engagement with said hanger-studs when the door is in inverted position, substantially as set forth.

3. In a grain-car door, the combination with a door and door-posts, of hangers secured to said posts, studs projecting from said hangers, swing-rods having their upper ends loosely connected to said hangers, studs projecting from said door and receiving the loose connection of said swing-rods, and hooks carried by'said door at its lower end to engage said hanger-studs when the door is in inverted position, substantially as set forth.
