Nov. 26, 1929. R. F. WHITE I GRAIN CAR noon Filed Feb. 18, 1927 Jrzzrazzibr Patented Nov. 26, 1929 UNITED STATES PATENT OFFICE GRAIN CAR DOOR,

Application filed February 18, 1927. Serial No. 163,288.

My invention relates to improvements in grain car doors, and the object of the invention is to so construct the doors that the grain dischar e orifice may be located centrally of the door and inaxinnun capacity and at the same time reinforce the bottorn edge of the door so that it will be grain tight and it consists essentially of the arrangement and particularly explained.

Fig. 1 is a front elevation of my door.

Fig. 2 is a horizontal section showing 31y door in place between two verticals forming the door opening of a grain car.

Fig. 3 is a vertical section on line 33 Figure 1.

Fig. 4 is a vertical section on line 4t- 1 Figure 1.

In the drawing lil-Ie characters of reference indicate corresponding parts in each figure.

1 and 2 indicate two verticals forming the side posts of the door of a grain car. 3 indicates the body of my door provided on its outer face with two

verticals

4 and 5 which when the door is in place bear against the inner iaces oi the side posts 1 and 2. 6 and 7 are verticals located interniediately between the verticals 1 and 5 and equi-distant on each side of the centre of the door body 8 is a 39 discharge opening formed in the door body in proximity to the bottom thereof. 9 is a spacing piece extending between the verticals (3 and 7, and 10 and 11 are spacing pieces which extend between the verticals at and 6 on one side of the ooor and 5 and 'i on the opposite side.

12 is an angle bar which is secured to the low *1 ends of the verticals a, 6, 7 and 5 by the bolts 12* extending through. each vertical and the ertical flange of the angle bar. The horizontal flange of the angle bar extends beneath the lower ends of the

verticals

1, 6, 7 and 5 and the

spacing pieces

9, 10, 11, thereby reintorcin the whole lower end 01 the door between the side posts 1 and 2 of the car between which the body of the door fits.

10 is a bar extending between the

outer verticals

4 and 5 and against which the upper ends of the

verticals

6 and 7 bear.

14; and 15 are securing plates connecting construction of parts as hereinafter more the upper ends 01 the

verticals

6 and 7 to the bar 10*. 15 is a plate provided with a segmental spherical orifice 16. The plate 15 is secured to the door body by means of the bolts 1'? and the verticals 6 and '7 and spacing piece 9 which overlaps the edges of the plate to hold it in position.

18 is a segmental spherical plate which is swung upon a bolt 1'? and is inserted between the plate 15 and the door body so as to form a cover for the discharge opening 8. The plate 18 is provided with a pin 19 by which it may be manually swung upon the central bolt 17 so to assume an inverted position to open the discharge opening 8 to permit the grain to be discharged.

When it is desired to close the discharge orifice the plate 18 is swung to the position snown in the drawing, the pin 19 being engaged by a latch 20 holding the plate in a locked and closed position.

The door is held between side posts 1 and 2 of the car by any suitable locking devices such as indicated at 21, plurality ot levers 22 swung upon bolts 28 and provided with ratchet teeth 24 adapted to be forced into the wood forming the side posts 1 and 2 of the car door so as to lock the door firinly in place.

h at I claim as my invention is z- T he combination with a grain car of a. door having a segmental orifice approaching a sen'ii-circlc, a pivot bolt extending through the door concentric to the centre of the orifice, a plate swung centrally upon the bolt forming a closure for the orifice, a frame plate conforming to the shape of the orifice and overlapping the eiilge thereof, securing bolts extending through the 113.1116 plate and door clear oi the cover plate, a handle extending outward from the cover plate, a gravity latch swung upon the frame plate and adapted to automatically engage the handle when the cover plate is brought to the closed position to lock the cover plate in such position.
