EDIVARD A. I'IILL, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO JAMES L. MALLORY AND EDGAR A. HILL, BOTH OF SAME PLACE.

GRAIN-DOOR FOR CARS.

SPECIFICATION forming part of Letters Patent No. 426,183, dated April 22, 1890.

Application filed October 17, 1889.

To all whom it may concern:

Be it known that I, EDWARD A. HILL, of Chicago, in the county of Cook and State of Illi- 1101s, have invented certain new and useful Improvements in Grain Doors for Cars, of which the following is a specification.

The principal object of my invention is to provide an auxiliary grain-door to be used when the car is loaded with the lighter grains such as oatsto retain which the ordinary grain-door is not sufiiciently high.

The object of my invention is, further, to provide an auxiliary grain-door which shall be adapted for use with a main grain-door sliding on fixed vertical rods at each side of the doorway, (such as that shown in Letters Patent of the United States, No. 406,399, granted me July 2, 1889,) and utilize the same rods for its support without interfering with the main door, the connection of the auxiliary door to the rods being such that when the auxiliary door is swung up the main door may be raised or lowered on the rods and swung up under the roof in the ordinary manner.

Another object of my invention is to make the vertical rods on which I hang both the main and auxiliary doors approximatelyflush with the door-posts of the car, so that they shall be out of the way and be protected from injury when the car is used for other freight than grain.

Myinvention consistsin the parts and combinations hereinafter described and claimed.

In the accompanying drawings, Figure l is a side elevation of my improved grain-door as seen from within the car. Fig. 2 is a central cross-section of the door and a part of the car. Fig. 3 is adetail of one of the hooks upon which the auxiliary grain-door is hung when not in use. Fig. at is a view, on an 011- larged scale, of the catches for holding the main and auxiliary grain -doors in contact with the side posts.

2 2 are the posts at the side of the ca1'-door. These posts are grooved at 2* for aportion of their length, and in these grooves the vertical rods 3 3 are fastened, the upper ends extending somewhat above the car-door opening and beyond the ends of the grooves 2. The depth of the groove is made such that the rods 3 3 are flush, or approximately so, with the Serial No. 327,385. (No model.)

inner face of the door-posts 2 2. As shown herein, to these rods the main grain-door 4 is secured by rings 5 5 and pivots 6 (5, and the pivots rest in bends or ledges 15 at the top of the rods when the door is raised, in the manner described in the patent granted to me July 2, 1889, No. 4106,39. The main door, when swung up under the roof of the car,is secured by the catch 7, as shown in dotted lines in Fig. 2.

Sis the auxiliary grain-door, which is attached by rings 9 9 to the rods 3 3, the rings 9 9 being secured to the door 8 by straps or bolts 1O 10, having eyes at their ends through which the rings 9 9 pass.

Fig. 1 shows the auxiliary door in place above the main door 1, and when in that position it is secured against rising and is also kept in contact with the door-posts by the catches ll 11, the preferred form of these catches being shown in the side view 11, a dog 12 dropping into a notch at the back of the catch 11, so tha-tit cannot move back until the dog 12 is turned so as to release it.

\Vhen it is not desired to use the auxiliary grain-door, it is swung up under the carroof, as shown in Fig. 2, so as to be entirely out of the way, and so as not to interfere with the manipulation of the main grain-door, whether it be swung up or lowered. To accomplish this, I provide hooks 13 13, (seen in side elevation in Fig. 3,) which engage in sockets ll 14 at or near the upper edge of the auxiliary grain-door. These hooks are so arranged on 8 5 a line above the ledges at the top of the rods as to elevate the auxiliary door as high as the rings 9 9 will allow it to rise, and the rings 9 9 naturally turn into such a position, as shown in Fig. 2, as to leave the bends 15 in the rods 3 3 free to receive the pivots of the main door.

The inner edge of the auxiliary door when swung up is sustained by the hook 16 in the ordinary manner.

As shown in Fig. 4-, the lower edge of the auxiliary door 8 and the upper edge of the main door 4 are kept in contact with the side posts 2 by the

fasteiiings

18 and 17, respectively. The fastening 18 consists of two links of chain fastened to the door and dropped over a hook attached to the door-posts. The fastening 17 is a hook which drops into a recess in the door 4. Its outer end 17 is extended rearwardly from the pivot, so that the hook may be released by a blow upon said extension. Either form of fastening 17 or 18 may be employed for both doors, to the exolusion of others, or any well-known means can be employed for the same purpose; but I prefer the fastening 18 for general use.

What I claim, and desire to secure by Letters Patent, is

1. The combination ,With the car grain-door working on fixed guide-rods on each side of the doorway provided with ledges at their tops, in which the main door is held when raised, of an auxiliary door independently attached to the guide-rods of the main door by rings encircling the guide-rods and loosely attached to the auxiliary door, and hooks, as 13 13, at-

tached to the car on a line above the ledges of the vertical guide-rods and adapted to en gage in recesses 14L 14 near the upper edge of the auxiliary door, whereby it is held when raised abovcthe ledges of the guide-rods, as and for the purpose described.

2. lhe combination, with the side postsof a car-door having grooves therein, of a vertical guide-rod extending along each of said grooves, so that its face is approximately flush with the inner face of the door-posts, a graindoor provided with pivots extending across said guide-rods, and rings encircling said pivots and rods.
