RAILWAY FREIGHT-CAR DOOR.

SPECIFICATION forming part of Letters Patent No. 300,315, dated June l0, 1884.

A pplcation filed April 15,1884. (No model.)

.T al?, whom it iii/(ty concern;

Be it known that l, BEN EYsTER, of Chi cago, in the county of Cook and State of I1linois, have invented a new and useful Improvement in Doors for Railway Freight-Gars, of which the following is a description, reference being had tothe accompanying drawings, in which Figure l is a side elevation viewed from the Io inside of the car. Fig. 2 is a transverse vertical sectional view on the line :c m, Fig. l. Fig. 3 is a modification of the construction shown in Fig. l, being a like view of aportion of the inside of the car and of a part of i 5 the door. Fig. i is a transverse sectional view of the traveler or guide-rail as constructed of T-iron, and showing the manner of attaching the door thereto; and Fig. 5 is a detail view showing a face-plate upon the door-jamb with 2o my improved device for securing the door when closed.

Like letters of reference indicate like parts in the different figures.

The object of my invention is to provide an inner door for railway freight-cars used in the transportation of various kinds of loose grain, which door may be cheap in its construction, and simple, durable, and effectual in its operation, and so secured to the car that whileV 3o it may be moved entirely out of position when necessary, it may yet remain firmly secured thereto.

In the drawings, A represents the side of an ordinary box or freight car, B B being upright pieces which serve as door-posts and constitute a part of the frame. Said car is provided with the usual outside sliding door A. (Shown in Fi g. 2.) In loading such cars with grain, it is customary to fill them to the depth io of about three feet, and to place one or more wide boards across the doorway to the necessary height to prevent the grain from ruiming out. rlDhese boards are pushed up from the bottom in unloading the car and the grain permitted to run out from beneath. The objections to this are that the loose doors or boards are in the way when not in use, and are liable to be stolen, while the ears are injured by the use of nails and other like means for securing 5o the same in position.

In the drawings, C represents my improved door, one end of which is adapted to rest loosely against the inside of the post B, or may lit into a socket or jamb attached thereto, as may be desired, while the opposite end rests in a similar manner against the inside ofthe post B.

Bolted or otherwise secured to the jamb or post Bl is a block, b, Figs. l and 2, to which is iirmly secured in like manner the bottom of a flat iron guide-bar, b, which latter extends 6o above the top of the door about the length of the block Z), when it is bent inward,d as shown in Fig.- 2, and bolted to said post B. That portion of the door C above the block b is sut ficiently elongated to extend through between 6 5 the bar b and the post B', as clearly shown in the drawings, which said extension is provided with an iron strap rigidly secured to said door G by bolts or screws, the upper or projecting end of which forms a loop or slot, c, as shown. 7o

Rigidly secured to the post B', at a point at or'about the top of the door C, is one end of a bar or guide-rail, D, which, passing through the loop oi' the iron c, is extended upward about the height of the block b, and thence, preferably, in a horizontal line somewhat more than the length of the door C, when the opposite end is rigidly bolted to the car at d.

E represents the usual wainscoting of the car, corresponding in height to that oi' the 8o door C, which is even with the inside of the post B. The loop c is so bent laterally as to permit the same to move up or down or horizontally upon the bar D when said door is operated. rlhe door is first raised vertically by being pricd upward from the bottom, when the grain runs out beneath it. Said door is then raised until the bottom rests upon the top oi' the block Z), when the loop c will have reached the horizontal portion of the bar D. 9o Said door may then be pushed backward to the position indicated by the dotted lines in Fig. l, when the bottom of the end upon which said loop is secured rests upon the block b2, the bottom of the opposite end being support- 9 5 ed upon the block Z). The top of said block b2 is provided with an upwardly-projecting guard-iron or clip, bi, to hold the door securely in position. The guide-rail D, as shown in Fig. l, is secured only at two points, and hence roo is more or less ilexible. The same is preferal as shown,

bly so made in order the better to accommodate itself to the movement of the loop thereon.

It is obvious that when the door is rst raised, so that its end rests upon the block b, a considerable leverage or prying force may be exerted upon the rail D; and to prevent the same from being displaced I secure a guardiron, f, to the frame-work of the car, beneath which the guide-railD passes, and which is sufiiciently distant from the rail to 'permit the passage of said door and loop. as shown in Fig. 2. Y

In Fig. 3 the guide-rail D, Ainstead of being straight, is shown as having an upward curve for raising the door in its backward passage, whereby the grain against the wainscoting E may not interfere with such backward movement of the door. Said rail (shown in Fig. 3) isfastened to the car at a sufficient number of points to render the same rigid and inflexible.

Said'rail is preferably made from T-iron, in 1 which event the connecting-iron or sliding dog c is correspondingly modified, as shown. in Fig. 4. Said iron D maybe bolted or spiked, as shown, or secured in anymanner which convenience and experience may suggest.

It is essential that the door C be rmly secured against the posts B B', as well as downwardly against the Hoor, thus preventing a leakage of grain. To accomplish this I preferably secure a metal plate, G, upon the face of the post B, to which in turn is loosely fastened a dog, H, having a slot, h, whereby the same may be moved up and down upon the rivet h. Said dog is provided with teeth h2 h3, the former being adapted to grasp the top of the door C, while the latter engages with a in h so thatadownward )ressure u on said p 7 7 p dog may exert a pressure against the post B, while at the same time the door is forced downward. To effect this downward pressure I provide an eccentric, I, above said dog,which is pivoted at i. To release the dog, said eccentric may be revolved sufficiently to permit the former to be raised, when it may be drawn outwardly and allowed to hang upon the bolt h', wholly without and disconnected from the door C, when the latter may be raised at will,

and slid back upon the guide-rail 5o D. A corresponding dog and eccentric may be used upon the post B; but it is believed that one will be sufficient. 'p

Having thus described my invention,what I claim,'and desire to secure by Letters Patent, is-

l. In a freight-car, the combination of the door C, adapted to rest against the inside of the usual door-posts of such car, having a slotted iron or loop rigidly secured to one end, and attached to and adapted to slide up on a stationary guide-bar commencing at or near one of said door-posts, and extending thence upward about the height of the block b, and thence horizontally to a point near the end of 6 5 said car, whereby saiddoor may be guided upward and backward and retained in position upon the side and between the doorway and the end of said car, substantially in the manner and for the purposes set forth.

2. In a freight-car, the combination of the door C, adapted to rest, when closed, against the posts B B, guide-bar b, looped or slotted iron c, guide-rail D, and means for locking said doorin position when closed, substantially 4as and for the purposes set forth.

3. In a freight-car, the combination of the door C, adapted to rest, when closed, against the posts B B', guide-bar b', looped or slotted iron c, guide-rail D, and dog II, substantially as and for the purposesispeciied.

4. The combination, with a freight-car, of the door C, adapted to rest, when closed, against the posts B B', guide-bar b, blocks b b2, looped or slotted iron c, guide-rail D, and guard f, for the uses tially as described.

5. In a freight-car, the combination of the dog H, having teeth h2 h3, pin h, and adapted to be raised and lowered upon a pin or bolt by means of a slot, h, an eccentric, ,or equivalent means for securing the same in position, and a sliding door, C, substantially as and for the purposes set forth.

and purposes substany BEN EYSTER. Vitncsses: p
