GRAIN-DOOR FOR FREIGHT-CARS.

SPECIFICATION forming part of Letters Patent No. 403,208, dated May 14, 1889.

Application filed October 19, 1888. Serial No. 288,549- (No model.)

f all whom it may concern:

Be it known that we, JOHN S. PATTERSON and J OHN R. LAWRENCE, citizens of the United States, and residents of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain. new and useful Improvements in Grain-Doors for Freight-Cars, of

. which the following is a specification.

The object of our invention is to construct a grain-door that may be readily attached to the freight-cars now in common use without employing attachments that would interfere in loading ordinary freight when the grain-door is not used, or that might be liable to be broken or injured, or be in the way when the car is used for transporting ordinary freight.

Our improved door is adapted to be swung up and retained under the roof of the ear, leaving no projecting attachments upon either the floor or uprights and to be readily thrown down and securely locked in place, the door being made in sections, so that the car may be used for transporting either heavy or light grain.

The invention will be first fully described in connection with the accompanying drawings, and will then be particularly referred to and pointed out in the claims.

In the drawings, in which like parts are indicated by similar reference-letters wherever they occur throughout the various views, Figure 1 is a side elevation of a freight-car provided with our improvements. The ordinary door is shown open and the grain-door closed and locked for the reception of grain. Fig. 2 is a vertical transverse section taken through line a: oof Fig. 1. The position in which the grain-door is thrown for ordinary freight purposes is shown in dotted line. Fig. 3 represents in both side and edge elevation the camlever for locking the door in its closed position. Fig.4 is an enlarged detail view of the devices shown in the upper left-hand corner of Fig. 2.

The car A and sliding door B are of ordinary construction, and need not be specifically described.

A represents two of the upright timbers of the car, forming the side stiles of the doorway, against which our improved door closes from the inside. The lower or main section,

0, of the door is hung upon a metal yoke, D, by metal l0op-plates cl. The yoke is hung in loops D, which are secured to the upper frame timbers, A of the car. The upper ends of the yokeD are bent toward each other, and the loops D are secured over these inward bends. The ends of the yoke, inside of the'loops D, are again bent at right angles toward the center of the car-body when the yoke is in its vertical position, for the purpose of preventing end play in the loops, and also to furnish supports for the top edge of the upper section, E, of the door when the lower section is closed. The upper edge of the lower door, 0, and the lower edge of the upper door, E, are matched to fit into each other, the meeting edges being metal cased, if desired, for strength and durability. The upper section, E, which is only used when light grain-as oats, for instaneeis to be shipped, is hung upon the yoke D by links 6, through which the ends of the yoke D pass, the links being hinged in lug-plates e, which are secured upon the inside of the door E, near the upper edge. WVhen the upper section alone is thrown up to the position shown by dotted lines, Fig. 2, its lower edge rests upon the inwardly-projecting ends d of the yoke D. A hook, 6 secured in the roof-timber a takes under the lower edge and retains the section in the upper position.

The lower door-section, O, has secured upon it, near its outer edges, two slotted cam-levers, F, the cam ends of which are to enter slotted plates f, which are let into the upright stiles A. The levers are beveled upon their edges, as seen at f in the edge view of Fig. 3, for the purpose of drawing the edges of the door firmly against the insides of the stiles A as the levers are turned down. The cam ends of the levers, bearing against the upper walls of the slotted plates f, hold the door firmly down, thus preventing its jarring loose and wasting grain when the car is in motion. The

levers F are held to the door by stud-pins passing through slots in the lever, so that when the lovers are thrown up the heavier ends will drop down and prevent locking when the door is thrown up.

The door-sections are provided with metal hand-holes g, for convenience in sliding them up upon the yoke. To throw the sections up so that the car may be used as an ordinary freight-car, the upper section is first thrown up and secured, as above described. Then the section C is pushed up on the yoke I) to its upper limit, after which it and the yoke D are turned up against the root of the car, and the lower bar of the yoke caught upon the hook D as seen in dotted line, Fig. 2.

By arranging the yoke so that its lower bar catches upon the hook I) there is no lia bility of the hook becoming disengaged. N0 locking device is required to hold the yoke and hook engaged.

\Vhat we claim asnew, and desire to secure by Letters Patent, is

1. The combination, substantially as specified, of the ear-body, the yoke D, suspended therefrom, the door the loops coupling it to the yoke, and the hook for catching over the lower bar of said yoke and retaining the door and yoke in the upper position.

2. The combination, substantially as hereinbe't'ore set forth, of the two door-sections, a swinging yoke suspended in the upper tinibers of the car-body for carrying the same, the links connecting the upper section to the yoke,whereby it is movable independently of the lower section, hooks hung from the carroot to catch over the lower bar of said yoke and sustain the sections in the upper position, locking-levers pivoted on the lower doorsection, and catches in. the posts to receive the locking ends of the levers, for the purpose specified.

3. The combination ot the car-body, the swinging door carrier D, having its upper ends bent, as shown, the loops 1), by which the yoke is hinged to the 1.'oot'-timl.)er ot' the car, the door 0 and loops coupling it to the swinging frame, the lovers 1 pivoted upon the door and having their locking ends beveled and cam-shaped, as shown, and the locking-plates f, recessed in the upright doorstiles, substantially as specified.

4:. In a grain-door composed of two sections hung upon. a swingin yoke, the combinatiiiin of: the upper section, E, the swinging links coupling the same upon the swinging yoke, whereby the said upper section is adapted to be pushed up and. swung against the roof of the car independent of the lower section, the inwardly-bent ends of the yoke for sustaining the lower edge of the door in its upper position, and the hooks pivoted upon the rooftinlber for sustaining the opposite edge, substantially as specified.
