CORNER POST FOR DROP-END GONDOLA CARS.

Application filed July 30, 1925. Serial No. 47,032.

This invention relates to corner post for that type of railway freight train equ1pment known as the drop end gondola car. Such a car is provided with rigid side walls but the end walls are hinged at their bottom edge so that they may be lowered or dropped so as to lie on the floor of the car. The object of such an arrangement is to permit the car to be used in transporting material which is too long to be carried in one car such as rolled steel beams, pipe and fabricated structural material. When the doors are in an upright or closed position, the car is used as an ordinary gondola car.

The corner post of such a car performs several functions and resists numerous different stresses. The corner post is the end member of the side truss or grider which is the main load carrying member and at the same time constitutes the side retaining wall. The corner post is one of the numerous side stakes which resist the lateral thrust of the lading against the side retaining wall, which thrust is augmented by the shifting of-the lading. WVhen the end gate is in an upright position its opposite ends bear against the opposite corner post so that these posts constitute the stakes for the end retaining wall and, furthermore, the post resists the longitudinal thrusts due to the shifting of the lading. They also provide a place for the latches which hold the door in an upright position.

The corner post must be strong enough to perform its functions and yet occupy the minimum amount of space so as not to interfere with the lading and to allow the greatest amount of clearance.

An object of the invention is to providea corner post having great strength to resist the various stresses imposed upon it and at the same time provide sufiicie t clearance so as not to interfere with the ading.

Another object of the invention is to obtain a corner post of minimum weight consistent with the required strength.

Fabricated or built-up corner posts are expensive and heavy and castings. are impractical on accountof replacements and re pairs; therefore, I prefer to make the corner post from a flat metallic (preferably steel) plate and form it into the required shape by pressing it in dies, preferably after heating. it. e v

' Another object of the invention. is to form a corner post from a fiat steel plate.

In the drawings:

Figure .1 shows an end elevation of a railway car with my device applied thereon. In the left hand half the'door is shown in a closed position while in the right hand half the door is shown in an open position, the door having been opened inwardly.

Figure 2 shows the fragmentary side elevation of Figure 1. I

Figure 3 is a sectional view of line 3-3 of Figure 1. Y

Figure 4 is a side elevation of the corner post in detail.

Figure 5 is anend elevation of corner post in detail.

Figure 6 is a section on line 6-6 of Figure 5.

The side wall 1 of the car comprisesthe top chord 2 and the side sill 3. The floor 4, and sill 5. striking casting 6, carry iron 7 and end sill angle 8 are all the usual part of the car.

The corner post comprises a. side portion 10 at the side of the car and an end portion 11 at the end of the car which portlons are substantially perpendicular to each other.

The side portion 10 is attached to the top side chord 2 at 12 and to the side sill 3 at 13 and is wider at the bottom than at the top to better resist the shifting tendency of the load longitudinally of the car. The side portion is provided with a vertically extending corrugation 14 which terminates within the ends of the post. This corrugation strengthens the post against the lateral forces in the car. and is terminated within the post to provide room for the attachments to the side chord (12) and side sill ('13) respectively. p

The end portion 11 of the corner post is preferably secured to the top side chord 2 and is also secured to the end sill at 15. The upper part of this end portion is conion stant in width (16) for the major portion to its length and is then curved (17) to form a wider lower part 18 for connection to the end sill or underframe of the car. By maintaining a constant width, the clearance for the lading is materially increased. The outer rim of the upper part and also preferably the rim of the curved part, is formed with an outwardly projecting flange 19. This flange materially increases the strength of the corner post on a horizontal section that is in planes parallel to line 33 in Figwere used it would soon he buckled and damaged and perhaps torn or split by contact with the iading. flhis flange increases the strength of the end portion of the post at its outer edge and enahles it"tobetter resist the stresses due to the shitting lading. When such lading as fabricated griders, pipe, telegraph'poles, otc., ei\*tend'heyond the corner 1 post they frequently come in contact with it, thereby causing 'it to act as a post and-also such lading EOlR'GtllHBS'lllOVG longitudinally of thecar and 'ii' the post was not flanged '(flange 19 the rim oif thesteel'plate might damage the lading or vice-Versa, the lading might dama 'e the-post.

The all "20 0f the'eorrugation 1'4 in the side portion is flush with the end portion 11 of this pest :asshown in Figure 6.
