' 7 claims. (01. 10s-9276) l An object of theinvention is to provide an end door for a car of the character described, which will `sustain the loads imposed thereon.

Another object o'f the' invention is to provide a 5' support `for the door when in lowered position.

In the appended drawing, Fig. 1 shows in elevation an end and portion of a side of a car with the end door in lowered position; Fig. 2 shows in elevation `one half of the end of the car of Fig. 1

with the door in raised position; Fig. 3 is a section `on lines 3 3 of Fig. 2; Fig. 4is a plan view of the car of Fig. A2; Fig. 5 shows a section on lines 5-5 of Fig. 2; Fig. 6 shows an enlarged view o! the door support on theunderframe; Fig. '7

r shows a modification oi the end door of Fig. 2. Referring now in detail to the drawing where like reference characters refer to like parts, the car as shown comprises an underframe I having a body 2 provided with end walls comprised of doors 3. The usual construction ofthe car of the type upon which this invention is adapted to be usedfis a side dump car. In sucha car, the body tilts about either or both sides of the 'underframe and is provided with side walls comprising doors hinged adjacent the iioor ofthe body and opening outwardly and' downwardly .at the side' towards which the body is tilted.. Itis to `be understood, however, that the present invention is not limited to such side dump cars but is adaptable to any type car as used in ditching service.

In ditching service, a train of cars are formed 'and loaded by means of a. loading device mounted on the floor of one car during the loading of the adjacent car and then moved along the length ofthe Vtrain as each succeeding car is lled; the licor of the body forms a track for the loading vdevice and the end doors serve to bridge the space between adjacent cars. In moving from one car to another the loading mechanisms, which are usually provided with caterpillar tractor treads Vso as `to be mobile, rst engage with the edge of the car end door and then move across the door before being .supported uponthe car 7 body floor. This causes heavy stresses to be ex- 'erted upon the car 'door and imposes concentrated loads beneath the treads of'theloading mechanism. f i' The door 3 comprises a pair of spaced vertical members 4 hinged to the floor of the body and joined at their upper ends by a member 5. The members 4 are shown as composed of channel shaped members disposed back to back with their Webs normal to the plane of the door. The member 5 'is also shown as a channel with depending flanges. The ends of the channels -4 being coped and secured to the channel 5. To the inner face of the members 4 aresecured planks 6 completing the door. The side and bottom ends of said door are preferably enclosed by angular members to form a protection therefor.

f 'I'he ends of the members 4 are hinged to the body as shown, and with the member 5 form a supporting bridge to be lowered between the cars. For this purpose, the pairs of members4 are spaced apart so as to correspond to the spacing of the tractor treads of the loading mechanism.

In order to retain the end walls in line with Athe iioor of the body when in lowered position, and to assist in supporting the weight of the loading mechanism, supports are provided on the door and car underframe. These supports comprise a member 1 securedto each of thepairs of members4 and bearing member 8 which is secured to the'underframe and adapted to receive the member 1.

Referring now to Fig. 1 of the drawing, where the door 3 is shown in lowered position, it will be observed that the treads of the loadingrmechan'ism 9, shown in dot and dash lines, first engage z the door at the point A, outwardly of the member 1. 'I'he load of -the mechanism 9 is down- Ward, causing ra lifting action at B, at the door hinge, which raises the end of the body 2. Obviously any upward -movement of the body at the point B causes a pivoting of the door upon the member 1 and a limited bodily movement of the door 3 inwardly of the car. To provide for this movement, a flexible connection between the member 1 and the door is provided, comprising a base I0 secured between the channels forming the member 4 and a connection between the member 1 and the base by means of a pin il. Lugs I2 project outwardly from the member 1 adjacent its'connection to the base l0 and engage the base to limit relative movement between the member 1 and the base Ill.v

The advantages of a door construction as described are numerous. By spacing the members 4 to correspond to the usual width of the treads on the loading mechanism, it will be obvious that the

members

4 and 5 form a track over which the mechanism moves. The plank t between the members 4 need form no part of the support for the mechanism and may be relatively light planks or sheet `material stiff enough to resist the thrust of lading when the cars are loaded.

By providing a exible connection between the doo-r 3 and the underframe at the member 1, distortion in the door is prevented and the limited movement of the door inwardly of the car prevents the door from being distorted or the breaking of the member 1.

To retain the door 3 in raised position any suitable means may be employed and to limit the vertical movement of the body a locking mechanism C such as shown in my copending application Serial No. 702,535, now Patent No. 2,081,975, may be employed.

In Fig. 7 of the drawing is shown a modification of the door, wherein the upper edge of the door adjacent the sides is deflected downwardly. The advantage of such a construction will be apparent upon a consideration of the conditions under which the car, upon which it is mounted, is operated. As the usual practice is to lower all the doors in a train of such cars, excepting the one being loaded, it is obvious that the cars moving upon a curved portion of track would swivel relative to each other and where any considerable movement takes place the lowered doors would engage each other adjacent the ends thereof. When, however, the edges lare formed as shown in Fig. 7, suflicient clearance is provided to prevent contact between adjacent doors.

It will be apparent to those skilled in the art, that various changes may be made in the details of construction of the loading mechanism supports 4 and E, in the manner of connecting the door to the cary and in supporting the lowered door upon the underframe without departing from the scope of the invention as set forth in the appended claims.

Having thus described the invention what I claim as new and desire to secure by Letters Patent is: y
