GEORGE T. COOKE, OF NEW YORK, N. Y.

RAILWAY CAR.

To all whom it may concern:

Be it known that we, IRA EVERETT and GEORGE T. CooKn, citizens 0 States, residing, respectively,

and State of Pennsylthe county of Bradford Vania. and at New York and New York, in State of New f the United at Sayre, in

the county of York, have invented a new and useful Improvement in Railway Cars, of which the following is a specification.

This 1nvention relates to improvements in railway cars of the type used ore or similar granu cars are usually constructbottoms with an ing coal, coke,

ed of metal having sloping for transportlate opening for the discharge of'cargo and are generally known as hopper cars. This invention relates more particularly to the construction" of a charge opening metal door to close ofa hopper car.

the dis It is an object of this invention to provide a strong, ight weight hopper cars w hich, should the metal door for doorbe prevented from closing tightly, will prevent the lading from sifting out during transportation, and another object is to provide a door of this character which will not necessitate the cutting away of any of its parts for the application of the usual strengthening bar that joins Hopper cars are which one general it T800 the adjacent doors.

gnized type in form comprises bottoms which slope downward from each end toward other portions sloping downward theretowards from the center sills passing through the edges of the end slope sheets an sheets with the hopper pairs on opposite sides of the central slope doors arrange 1n of the center sills adapted to close charge opening between the the center of the car,

lower d body the disend slope sheets and central slope sheets and it is, therefore,

not considered necessary descrlbe in more detail this car.

tion is illustrated upon 'th drawing, yet it is to minor detail changes may departing from to illustrate and 1 sides and bottom edges of the hopper door general type 0 While the preferred form of this invene accompanying be understood that be made without the scope thereof.

Fig. 1 illustrates this improved hopper door in vertical section through portion thereof.

Fig. 2 is a view in perspe proved door detached from the. central cave of this am the car body.

parallel longitudinal d sired, which are preferably Serial No. 501,591.

The embodiment of this invention as illustrated includes a hopper door attached by hinge butts to the under side and above the bottom edge of an end slope sheet between the center and side sills. The body 1 of the door is shaped to correspond with the discharge opening and extends slightly above and on the under side of the lower edge of the end slope sheet 2 and below and beyond the lower edge of the central slope sheet 3. The body of the door may be provided with corrugations 4, if depressed upward from the outer side of the door and extend in the general direction of the discharge of the load. The'door is secured to the hinge butts 5 by hinge straps 6 secured to the under side of the door body as shown. The bottom and'sides of the door body are provided with a continuous upwardly extending flange 7 so as to receive the side wallsand central slope sheet of the hopper when the door is closed, as shown in Fig.

That part of flange 7 which is integral with the lower edge of the door is bent to form an obtuse angle with the body 1 of the door so that when the door is open this flange is positioned so that the lading will not be retained thereon but will 'slideofi'. This eliminates the necessity of the cars being cleaned after each trip. It also permits a full head rivet to be used to secure the bottom stiffener angle to the central slope sheet 3.

The door is adapted, under normal conditions, to make a tight closure with the bottom edges of the wall of the hopper but often during travel from different causes the tight closure becomes imperfect and the jolting of the load during the movement of the car will cause the lading to leak or sift through between the door and walls of the hopper. The upstanding flange on the embracing the hopper walls will insure the retention of the lading when the closure between the door and perfect.

It is customary to rigidity metal hopper doors by down turned flanges along the bottom and side edges and also to connect the pair of doors operating together on the same side of the transverse center of the car by a rigidifying brace, as illustrated, usually in the form ofchannel irons 8 secured to the hopper walls 15 1mx door bodies which necessitate another operation in the manufacture of the door as the down turned flanges on the adjacent sides of the doors must be cut away in order that the connecting brace may be secured to the door body.

The hopper door constructed in accordance With this invention simplifies the manufacture, allows for the ready attachment of the connecting brace and prevents the loss of the lading if the doors are imperfectly closed.

What We claim is:

1. In a railway car having hopper walls, a metallic door provided with a continuous flange about the side and bottom edges there of extending upwardly from the door body so as to embrace the lower edges of said hopper Walls, said flanges deflected from the door body to such an extent that the upper part of said flange is further away from said hopper Wall than the lower part of said flange.

2. In a railway car having hopper Walls, a metallic door provided With a continuous flange about the side and bottom edges thereof extending upwardly from the door body meaeoe so as to embrace the lower edges of said hopper walls. the flange on the'bottom edge deflected from the door body to such an extent that the upper part of said flange is further away from said hopper Wall than the lower part of said flange.

3. In a railway car having hopper Walls, a metallic door provided with a continuous flange about the side and bottom edges thereof extending upwardly from the door body so as to embrace the lower edges of said hopper walls. the angular relation of said flange to the body of the door being different than the angular relation of the said hopper Walls to the body of the door.

l. In a railway car having hopper Walls, a metallic door provided with a continuous flange about the side and bottom edges there of extending upwardly from the door body so as to embrace the lower edges of said hopper walls, the angular relation of said flange to the body of the door being greater than the angular relation of the said hopper walls to the body of the door.
