END STRUCTURE FOR RAILWAY CARS.V

Application med october 19, 1923. semina. 669,522.k

My invention relates to the construction of railway cars having metal end or side structures or walls made of one or more metallic plates or panels formed with integral vertical or horizontal reinforcing, stiffening and bracing corrugations or panels to resist the thrust of shifting loads. While efforts are made to block the lading in the car, the shocks caused by the heavy locomotives, the emergency air brake and the classification hump tear the lading away from its moorings and throws it against the end of the car, and the lateral weaving of the car throws it against the side of the car.

" The invention is readily adaptable to box,

gondola and other types of railway cars.

One of the objects of the invention -is to provide a wall element which has great strength to resist the torsional and weaving stresses which exist in a railway car when moving in service. These stresses are caused by the inert-ia of the roof and superstructure when the train is suddenly stopped; rough or uneven track; the superelevation of the track on curves; the lateral inertia in rounding curves; eccentric thrust due to the lading being secured to one side of the car; the cars being cornered; the use of push pole pockets; etc. Such stresses rackand distort the superstructure which decreases the life of the car, and also causes the car to leak grain, sand, and other such material. Furthermore, such stresses cause leaky roofs and leakyv and inoperative side and end doors.

The tendency of an all metal end wall to bulge is resisted partially by the corrugations, stilfening members or whatever means have been provided to transmit such stresses to the side wall or frame members of the car. Such tendency is also resisted by the corner post of the car acting as a vertical beam supported at top and bottom and sustaining a horizontal load; in other words,

' the bulging of the end would pull the opposite corner posts toward each other. This bulging also tends to pull the end or side plate downwardly and the end or side :fl-ill upwardly. Another object of the invention is to reinforce the frame members against thrust perpendicular to their length by means forming a part of a corrugated or otherwise reinforced metallic end wall.

Since the corrugated metallic wall is braced against buckling it in itself has considerable resistance to the lateral stresses but the wall must be` well secured to the frame members, (post, sill and plate) in order to secure the co-operation between these frame members and between the metallic wall and the frame members. Another object of the invention is to obtain an improved method of securing a corrugated metallic wall to the frame members of the car.

In my construction the central portion of the metallic plate is pressed so as to form a continuous web substantially perpendicular to the plane of the wall. This central" portion is reinforced with'corrugations or other well known means, but ysuc-h reinforcements terminate short of the web so that the web extends continuously and uninterruptedly on three (or preferably four) sides of the wall. This web may rest against and be secured to the adjacent frame member, such as cornery post, end sill or end plate. A metallic plate thus formed constitutes a yoke connected by a member, which member is prevented from buckling by stifening means. Such a construction when installed on a vfreight car has great strength to resist the lateral stresses set up by the car in motion. Another object of the invention is to provide `and continuously carry such a web around a corner ina steel plate in such a manner that it is practical to form by pressing without tearing the metal.

rlhe end sill 1; end plate 2, ridge pole 3;

fascia 4;; roof 5; corner post 6; outside sheathing 7 g side lining 8, and end lining 9 are all the usual parts of a railway box car.

The metallic wall 10 is secured to the end sill 1 by truss rods 11 and bolts 12; to the end plate 2 by bolts 13 and to the corner post 6 by bolts 14, all of customary construction.

The central part 15 of the end wall is pressed inwardly so as to form

webs

16, 17 and 18 which are substantially perpendicular to the plane of the wall 10.

Webs

16, 17 and 18 are in reality one continuous web forming the tour sides of a rectangular depression, which construction materially reinforces the metallic end wall to enable it to resist the lateral weaving of' the car.

1t is difficult to press such a construction in steel without tearing the corners where the webs intersect, therefore, li have provided a special construction where

webs

16 and 18 intersect and 17 and 18 intersect, which is shown in Fig. 7. The web 18 is substantially perpendicular to the plane ot the plate between points 19 and 2O and web 16 is substantially perpendicular to the plane of the plate between points 21 and 22 and web 17 is substantially perpendicular to the plane oit the plate between points 23 and '24. At. the corners, for instance, between points 2O and 22, the web changes from a perpendicular to an oblique position and back to a perpendicular position so as to relieve the metal in the pressing operation, and at the same time, strengthen the corner against lateral weaving stresses. The central portion 15 is reinforced against horizontal loads and buckling by integral stiffening ribs or corrugations oit any desired form.

The central portion 15 is preferably formed so that the web 16 is in contact with the end sill 1 and may be secured thereto by bolt 25; web 17 may be in contact with end plate 2 and secured thereto by bolt 26 and side webs 18 may be in contact with corner post G or side wall 27 and secured thereto by bolts 28. VJith this construction the central portion 15 is depressed so that this surrounding` continuous web is in contact with and may be secured to the adjacent f'ame mem bers of the car, thus greatly strengthening the frame of the car against torsional lateral weaving. This continuous web may or may not be secured directly to the adjacent frame 7 members.

Fig. 5 shows a modification wherein the metallic end wall is extended and flanged as at 3() so as to overlap the corner post (and possibly the sheathing 7) of a double sheathed type of box car. Bolt 29 may extend to engage both webs 18 and flange 30.

Fig. 6 shows a modification of the construction described in Fig. 5 applied to a sin- `ale sheathed type of box car (or a gondola. car) with a wooden side wall. Flange 31 is extended to accommodate another row oi bolts 32. It will be noted that the construction shown in Figs. 5 and 6 form a channel section between lines 33-34 and 35-36 respectively against loads in the direction of

thearrows

37 and 38.

Fig. 8 shows a construct-ion wherein both the side and end walls overlap the corner post 6 and are extended and bent to form flanges. A system of bolts is shown which ties the side and end wall plates together and to the corner post.

Figs. 9. 10 and 11 show a modification wherein the central portion is pressed outwardly to form

webs

51, and 53 which are joined at the corners to form a continuons web. In this modification the construction is applied to a steel frame car having end sill 541; end plate 55; corner post 56; side sheathing 57; and inside lining 58, all of usual construction. The end may be lined with end lining 59 and nailing strips 60 if desired.

A different type of integral reinforcing corrugation is shown in this group than `is shown in group Figs. 1 to 3.

The continuous web (51, 52 and materially reinforces its adj acent frame members. particularly at the corners of the wall, to resist lateral weaving of the car.

The reinforcing ribs or corrugations 39 are forme-d in the central portion and extend continuously transversely across the een tral portion but terminate within the central portion so as not to intersect the web. 1With this construction the continuous web extends uninterruptedly around the perimeter of the depressed central portion.
