GRAIN-CAR DOOR.

Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed January 25.1905. Serial No. 242,637-

To all whom, it may concern:

Be it known that I,WILLIAM H.MCMACH-EN, a citizen of the United States, residing at Superior, in the county of Douglas and State of Wisconsin, have invented certain new and useful Improvements in Grain-Car Doors, of which the following is a specification.

My invention relates to the construction of grain-car doors and the means for fastening doors in position, and has for its object the provision of a door that is grain-proof and that is provided with simple and easily-0perated means for fastening the door in position.

My invention will be described in detail hereinafter and illustrated in the accompanying drawings, in which Figure 1 is a view of a fragment of a car, showing the inside and the door in position and locked; Fig. 2, a similar view of the exterior of the car and door in a locked position; Fig. 3, a horizontal sectional view of the door and'casing; Fig.4,a view showing the means for locking the sides of the door; Fig. 5, a de- I tail view of one of the side-locking means Figs. 6 and 7, detail views of the eccentric for securing the bottom of the door; Fig. 8, a

View of the plate for closing the small opening in the door, and Fig. 9 a fragmentai view pif the edge of the bottom of the door and the cor.

In the drawings similar reference characters indicate corresponding parts throughout the several views.

A represents the side of the car, B the doorcasing, and C the fioor, having a groove 0' therein across the inside of the door. On each side of the casing B is secured a metal strip D, which is bent so as to form a V- shaped bead d. p

E represents the door divided in two unequal portions and secured together by hinges F on the inside of the door, while G represents handles on the outside of the door for manipulating it. The ends of the door E are grooved, as shown at e, to receive the beads d, and the edges slotted, as shown at H,

to receive the links I, secured in eyebolts i in casing B, J being keys to fit into the protruding ends of links I.

K represents wear-plates on the ends of the door having their outer edges turned outwardly, so as to form a flange 7c to hold the keys J in place.

The bottom of the door fits into groove 0 and is locked to the floor by means of links L,

mounted in eyebolts Z, secured to floor 0, and eccentrics M, journaled on the door by means of shafts N, which have on their other ends a handle N for rocking the shafts. The edge of each eccentric M is grooved, as shown at m, to receive the link L in looking the door, the edge of the disk nearest the shaft N being smooth and tapered to an edge, as shown at m, so as to insure the link dropping off of the eccentric in unlocking the door.

0 represents angle-iron guides at the lower end of the door.

A small hole P is provided in the door. for extracting the grain before the door is removed, which is covered by a plate Q, having slots in each end adapted to fit staples R on the door, the plate being held in position by keys S.

In operation the door is secured in position by swinging the links I into slots H and inserting the keys J into the protruding ends thereof and by securing the links L on the eccentrics M. When the car is loaded with grain, it will be readily seen that the beads 61 and grooves e and the bottom of the door fitting in groove 0 in the floor of the car prevents the escape of the grain. To remove the contents of the car, the plate Q is first removed from the hole P, which allows sufficient grain to run out to permit the insertion ofthe operators arm in the opening P to remove the keys J from the lower sectlon of the door. The handles N are then operated to turn the eccentrics M from engagement with the links, and the lower part of the door may be swung inwardly and upwardly, so that the contents of the car may be got at by the operator. Should it be desired to remove the Whole door from the casing, the keys J in the links I in the upper section of the door should be removed.

It will be readily seen that the links I permit the swinging of the door on hinges F, which could not be done by having fixed studs without having the slots I-I so large that the fasteningof the door would be insecure. Having thus described my invention, what I claim is 1. In combination with a grain-car and door, links secured in the floor of the car inside of the door, and eccentrics ournaled on the door having the edges of their widest part provided with grooves to receive the links and the edge of the narrowest part tapered, substantially as shown and described.

2. In combination with a grain-car and its door-casing, links secured in the sides of the casing and also in the floor of the car, a door having slots in its ends to receive the links in the casing, and eccentrics journaled on the door to engage said links, said eccentrics having their widest parts provided with grooved edges and the narrowest part tapered, sub stantially as shown and described.

I 3. In combination with a grain-car and its door-casing, links secured in the sides of the casing and also in the floor of the car, a door having slots in its ends to receive the links in the casing, keys to fit in said links, and eccentrics journaled on the door to receive said links, said eccentrics having their widestparts provided with grooved edges and the narrowest part tapered, substantially as shown and described.

4. In combination with a grain-car and its door-casing, vertical beads on the sides of said casing, links secured adjacent to said beads, the floor of the car having a groove adjacent to the door-casing, links secured to the floor adjacent to said groove, and a door having grooves adjacent to its side edges to fit the beads on the casing and slotted to receive the links on the casing, the bottom of said door adapted to seat in the groove in the floor, and eccentrics journaled on the door and adapted to engage the links secured to the floor, said eccentrics having their widest parts provided with grooved edges and the narrowshaped beads on the casing and the end of the door slotted to receive the links on the casing, a strip of metal secured to the sides of the door and turned outwardly to form a flange at each end of the door, keys adapted to seat in the ends of the links protruding from the slots in the door, the bottom of the door adapted to seat in the groove in the floor, eccentrics j ournaled on said door and having the edge of their broad part grooved to receive the links secured to the floor, the narrow partsv of said eccentrics being tapered, an opening in the door, and a plate adapted to be secured over said opening, substantially as shown and described. v

In testimony whereof I hereto afiiX my signature in the presence of two witnesses.
