CORRUGATED STRUCTURE FOR RAILWAY CARS.

Application filed October 23, 1925.

My invention relates to the construction of railway cars having parts formed of metallic plates which are subjected to lateral, buckling and sometimes torsional stresses. Said parts are made of one or more metallic plates or panels formed with vertical or horizontal corrugations or other integral stiffening or bracing means to resi t such stresses. While eiforts are made to block the lading in car, the shocks caused by the heavy locomotives. the emergency air brake and the classification hump tear the lading away from its moorings and throw it against the end of the car, the lateral weaving of the car throws it against the side of the car, and the impact throws it against the bottom of the car. My invention is adaptable to several parts of a railway ear, such as side doors, side walls, floor sheets (sloping or otherwise), hopper doors. roof sheets, etc, but it is especially adaptable for use as the end wall of a railway car and is also adaptable to box, gondola or other types of cars.

One ofthe objects of the invention is to provide metallic parts of a railway car which have great strength to resist the torsional and weaving stresses which exist in a railway car when moving in service. These stresses are caused and superstructure when the train is suddenly stopped; rough or uneven track; the superelevation of the track on curves; the lat.- eral 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 rack and distort the superstructure which decreases the life of the car, and also causes the car to leak grain, sand an other such material. Furthermore, such stresses cause leaky roofs and leaky and inoperative side and end doors.

The tendency of an all metal end wall to bulge is resisted partially by the corrugations. stiffening members or whatever means have been provided to transmit such stresses to the side wall or frame-members of the ear. Such tendency is also resisted by the corner post of the car acting as a vertical beam supported at its 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) sill upby the inertia of the roof Serial No. 64,466.

wardly. 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 con siderable 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.

A part of the metallic plate is pressed to form a panel 14 surrounded by an integral part of the plate positioned angularly to the plane of the panel. If this surrounding partconstitutes the edges of the plate then it would technically be called a flange. However, it may be provided with a laterally extending part- (or flange 28-27) so that the surrounding part would then technically be called a web. This laterally extending part is not an element of the broader claims of this application, therefore. to avoid the use of two different words to designate the same element. in different claims, the word web is used to designate that part of the plate surrounding the panel and positioned at an angle thereto whether it constitutes the edges of the plate or not.

It has been proposed to press the central portion of a metallic plate (or plates) so as to form a continuous Web or flange surrounding a panel and to reinforce this panel by horizontal corrugations or other integral reinforcements which traverse the panel and terminate adjacentthe opposite portions of lll) (all

the web or flange. In such an arrangmuent the load upon the horizontal corrugations is transmitted to the continuous web or flange only through the intermediate means of the flat portion of the plate lying between the end of the horizontal corrugations and continuous web or flange. It has also been pro posed to press the central portion of a metallic plate (or plates) so as to form a web or flange (supposedly) surrounding a panel and to reinforce this panel by horizontal corrugations or other integral reinforcements which are the same depth as the web or flange where they merge into it. In such an arrangen'ient the web or flange, as a beam,

is destroyed. In my construction the trans verse corrugations destroy only a part ol the value of the web, leaving a remaining portion which extends continuously around the panel to receive the stresses from the horizontal corrugations and to function as a beam and a stiffener. Such stresses are transmitted direct y to the remaining portion of the web. 7

That portion of the web between the corrugations serves as an excellent place for an attaching bolt or rivet because a bolt or rivet so positioned then also restrains the corrugations against deflection. Further more, a bolt or rivet so positioned prevents the web from buckling as it has a tendency to do when acting as a beam.

, In the drawings the usual parts of the car are shown such as the end sill 1; end plate 2; side sill 3; side plate 4; side girth 5; corner post 6; side lining 7; side sheathing 8 end lining 9 and end fascia 10.

In my construction the central portion of the metallic plate 11 (or plates 1112) is pressed to form a continuous web 1316 surrounding a panel 14. This panel 14- is reinforced with corrugations or integral ribs, some of which 70 traverse the panel (in the preferred form) and merge into a part of the opposite portions 16 of the continuous web, while other shorter corrugations 74 traverse a partof the panel and merge into the panel preferably adjacent the opposite portions 72.73 of the web. The two types of corrugations 7074l may be positioned alternately but their relative number and position may be diversified to suit conditions. The shorter corrugations Tel are preferably shallowerthan the longer corrugations 70. The remaining portion 26 of the continuous web extends continuously and uninterruptedly on three (or preferably four) sides of the wall. This Web receives the load from the corrugations and formsa beam or stiffener to prevent bulging in transmitting the load from the corrugations to the frame of the car. These remaining portions of the vertical parts 16 of the continuous web are prevented from buckling or deflecting by being formed integral with the horizontal parts 13 of the continuous web preferably by radial portions 17). The web preferably lies against the adjacent frame member, such as corner post 6, end sill 1 or end plate 2 and is secured thereto by bolts 18 which are preferably positioned between the corrugations. Other means 19 are provided to secure the plate to the frame member which are preferably positioned in alignment with the corrugationsi' These two means may be used jointly or severally. The plate is secured to the end sill l. by bolts 202l and to the end plate by bolts 2223.

Figs. 9 and 10 show an enlarged section of the corner post and illustrates the relation of the web, the corrugations and the attaching bolts 18 and 1.9.

\Vhile I have shown and described the corrugations positioned horizontally, it is understood that the corrugations may extend vertically or otherwise, and still come within the scope of the invention, and, fur thermore, while I have described and claimed the wall made of a plate, it is understood 7 that .it may be made of one or more united plates and still come within the scope of the invention.
