EMBOSSED METALLIC PLATE.

Application filed December 2, 1926. Serial No. 152,252.

My invention relates to means of reinforcing a metallic plate by forming integral corrugations, embossments or ribs therein and resides in the particular and peculiar configuration and relation of the corrugations to obtain certain desired results.

An object of the invention is to form and arrange a plurality of corrugations in a metallic plate so as to obtain a desired proportion between strength, rigidity and resiliency.

Another object of the invention is to obtain this result with the least amount of raw material and to provide a finished article of the least possible weight consistent with strength requirements.

Another object of the invention is to obtain the desired strength, rigidity and resiliency by forming a metallic plate with integral embossments, each embossment comprising a plurality of constant width central portions which converge and merge together adjacent the ends of the embossments and also forming corrugations in the same metallic plate between the adjacent ends of the embossments.

Another object is to provide such a corrugated metallic plate which can be formed by pressing it (when heated, if necessary) between dies which move toward each other in one direction only.

The construction may be used wherever a strong, resilient panel is desired, but is especially adaptable for railway car structures, such as end walls, side or end doors, hopper doors, floors, roofs, etc., and while I have shown and claimed herein the construction used as an end wall of arailway car.

It is well known that the end walls of railway cars are more likely to be broken or otherwise injured than the side walls. This is due to the inertia thrusts and pressures caused by the shifting of the cargoes when the train starts or stops. These thrusts may be local, tending to distort the end in some particular spot, as, for example, when a piece of piping or lumber shifts lengthwise imparting a blow against the end wall of the car; or there may be a general tendency to break out the ,end wall as a whole or tear it away from the framing. For the purpose, therefore, of greater strength and durability, car ends have been constructed of metal plates corrugated or formed with ribs to impart the desired Strength, rigidity and. resiliency. My conbe made stronger where greater strength is required. A wooden inside lining is required n a railway house car for blocking the lad mg to and for compliance with the requirements of the Bureau of Explosives of the American Railway Association. Such awooden lining can be easily applied to my construction.

WVhile I have described my configuration and arrangement of corrugations as used to reinforce the plates of an end wall of a railway car, similarly reinforced plates may be used as a side door for a railway car by providing a frame around itsouter edges, or such a reinforced plate may be used as an end door of an automobile railway car by providing the necessary hinges, latches and the usual attachments; also it may be used to reinforce a metallic plate when used as a drop door of a hopper car by providing the hinges and other usual raising and locking mechanisms.

In the drawings:

Fig. 1 shows a railway box car with my de vice applied thereon.

Fig. 2 is a section on line 22 of Fig. 1.

Fig. 3 shows a railway gondola car with my device applied thereon.

Fig. 4 is a section on line 4-4 of Fig. 3.

Fig. 5 is a detail of a plate reinforced by my arrangement of embossments.

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

Fig. 7 is a section on line 7-7 of Fig. 5.

Fig. 8 is a section on line 8-8 of Fig. 5.

Fig. 9 is a section on line 99 of Fig. 5.

Fig. 10 shows a modified form wherein the embossments and corrugations are of the same depth and are of constant depth. Fig. 10 is similar to Fig. 6.

The end wall structure comprises a panel composed. of one or more metallic plates with Furthermore, such my particular configuration and arrangement of embossments formed therein. In Figs. 1 and 2 the embossed plates 1, 2 and 3 extend from top to bottom of the end wall and may be formed with integral flanges 4 along the vertical edges of the outer. plates which overlap and are secured to the side wall 5 of the car by any suitable means. The top edges of the plates are secured beneath the fascia board 7 and the meeting edges of the plate overlap and are secured tog-ether by rows of rivets 8 and the lower edges of the plates are secured to the end sill 9.

Figs. 3 and 4 show a form of my invention applied to a gondola type of railway car wherein only one end panel whichextends from side to side of the car and may be provided along the ill vertical edges with flanges which overlap and are secured to the side walls by any suitable means. The top edge of the plate is secured to a top chord, while the lower edge is secured to the end sill.

The plate is provided with a plurality of parallel embossments, which embossments each comprise a plurality of parallel central portions 11 which are of constant width and preferably of constant depth which merge together adjacent the opposite ends 12 of the embossments. The ends of the embossments may be shallower than the central portions.

The metallic plate is also provided with minor corrugations 13 positioned between the ends of the embossments with their sides preferably parallel to the adjacent embossments. When the central portions of the em possments are relatively deep these minor corrugations preferably correspond in depth to the adjacent ends of the embossments or if the embossments are of constant depth then the minor corrugations are preferably also constant in depth and of the same depth as the embossments or these minor corrugations may decrease in depth toward'the middle of the plate, as illustrated. t

The outer ends 14 of the embossments and minor corrugations terminate into the plate adjacent its edge in line with each other and preferably adjacent the frame member (sill, plate, stile or post) of the car to which the plate is attached. ,The inner end 15 of the minor corrugations terminate into the plate between the embossments. The central portions of each embossment and of adjacent embossments are spaced apart distances equal to their widths so as to form a sinuous configuration; furthermore, the ends of the embossments and the minor corrugations are spaced apart distances equal to their widths to form a sinuous configuration.

The drawings illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modiplate is used to form the fications thereof within the scope of the I claims will occur to I claim:
