Car End Constructions, of which the following is a full, clear, and' exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in whichl l Figure 1 is an elevational view of a car end ofmy improved construction.

My invention relates generally to railway car end construction, and more particularly to the car end wall. Y

In railway cars, and particularly those designed for and used in freight service, the end portions of the car body, and particularly the end walls, are subjected to severe stresses and strains' resulting from shocks and vibrations, and by reason of the sudden starting and stopping of the cars and the shifting of the load or contents, of the cars while the latter are in transit.

I propose to construct a car end wall from sections of sheet metal, the same being provided with pressed ribs or corrugations arranged so as t materially strengthen and stiften the end wall and the anels thereof, thereby providing a construction which will eectually resist internally or externally applied pressure and the resulting stresses and strains. y

The principal object of my invention is to construct a car end wallfrom a plurality of sections of material, preferably sheet metal, each section being reinforced and stiffened by means of ribs or corrugations pressed in the sheet metal, thus providing a comparatively simple, inexpensive vconstruction which can 'be readily utilized in connection with an Ordinary car underframe and superstructure, and which end wall f r -plate will be eective in resisting all stresses resulting from, shifting loads, ordiparatively narrow. The main sections 1 and.

2 are preferably formed of lapproximately rectangular pieces of sheet metal, and the upper edge of the top section 2 is shaped so as to conform with the shape of the car roof.

The side and lower edges o f the section 1 and the side and upper edges of the section 2 are bent at right angles to the plane occupied by the main body portion of said sections in Order to form marginal flanges l, whereby the end wall or plate may be readily attached to the framey of the car body.

The horizontally disposed section 3 is, as heretofore stated, comparatively narrow and its ends are bent rearwardly, as designated by 5 to correspond with the bent side edges of the sections l and 2, and are arranged for attachment to frame portions of the car body. -The lower edge of the section 2 overlies the upper edge of the intermediate' section 3, and the lower edge of said interribs or corrugations 7, the same being pressed from the material of which said sections are formed, and said ribs or corrugations are preferably deepest at their centers and gradually decrease in depth toward their ends. These ribs or corrugations are preferably arranged at equal distances apart 'and the series of ribs or corrugations in one of Vso the plates are preferably in alinement with the corresponding ribs and corrugations of the other plate.v .4

Formed in the lower plate 1 adjacent to the outermost pair of ribs or corrugations are ribs or corrugations 8 which converge upwardly, and these ribs or corrugations are preferably deepest at their centers and gradually decrease in depth toward their ends.

Formed in the upper section 2 and preferably in alinement with the converging ribs or corrugations 8 are corresponding ribs or corrugations 9 which converge upwardly, and these last mentioned ribs or corrugations are formed like the other ribs or corrugations,.-that is, they are deepest at their centers and gradually decrease in depth toward their ends.

Formed in the intermediate narrow section 3 and extending practically the entire length thereof isV a rib or corrugation l() which is preferably deepest at its central portion, and which gradually decreases in depth toward its ends. The intermediate section 3 which is stiifened and reinforced by the rib or c orrugation 10 is rigidly fixed to the corresponding edges of the main sections 1 and 2, and thus forms a very strong and rigid reinforcement for the end wall or plate at a point approximately midway between its upper and lower edges, and said end wall or plate v4is further reinforced and stiifened by the vertically disposed ribss or corrugations 7 and the inclined ribs or corrugations 8. Such construction provides a car end wall or plate which is very strong and durable and which is particularly effective against stresses tending to distort said end Wall.

My improved construction effects a considerable saving in the initial cost of construction ofthe car end walls in the cost of repairs and by forming the entire end in sections the latter can be much more easily handled by the workmen during the formation of the ribs or corrugations and in the assembling or repairing of the structure than where an end plate or wall is formed in a single large piece. f

The ribs or corrugations are arranged and disposed so as to stifen and reinforce the en d wall to a maximum degree, and the impact of all internallyan'd externally applied shocks or blows and all service strains and vibrations will be transmitedv directly to the' underfraine sills and plates forming a part of the car body frame.

It will be readily understood that minor changes in thesize, form and construction of the various parts of my improved car end can be made and substituted for those herein shown and described without departing from the spirit of my invention, the scope of which is set forth 1ntheappended claims.

I claim:

1. As a new article of manufacture a car end comprising a comparatively wide upper section, a comparatively wide lower section, and a comparatively narrow intermediate section, the`upper edge of which intermediate section lies inside and is fixed to the lower edge of the upper section, the lower edge of which intermediate'section lies outside and is liXed to the upper edge of the lower section, and said intermediate section having pressed therein a longitudinally reinforcing and sti'ening rib or corrugation, thereby. forming a transversely disposed reinforcement at a point substantially midway between the upper and lower edges of the car end.

2. As a new article of manufacture, a car end-comprising a comparatively wide lower section, a comparatively wide upper section, a comparatively narrow intermediate section, the lower edge of which upper section overlies the upper edge of the intermediate section, the lower edge of which intermediate section overlies the upper edge of thel lower section, and each of which sections has pressed therein a reinforcing and stiffening rib or corrugation.

As a new article of manufacture, a car end comprising a comparatively wide corrugated lower section, a comparatively wide corrugated upper section, a comparatively narrow corrugated intermediate section, the

lower edge of which upper section overlies the upper edge of the intermediate section, and the lower edge of which intermediate section overlies the upper edge of the lower section.

gated sections of sheet metal, the corrugation of one section lying approximately at right angles to the corrugation of the other lsections, the lines of separation between said sections being horizontally disposed and the sections being arranged so that a watershed is provided on the exterior of the car end forming a protection against the entrance of water and dust into thecar through the joints between said sections. v 5. A car end comprising a series of sections of sheet metal, each of which is provided with a pressed stiffening rib or corrugation, the rib or corrugation of the intermediate section lying substantially at right angles to the ribs or corrugations of the other sections, the joints between which said sections are horizontally disposed, and said sections being arranged so that a watershed is provided on the exterior of the car end forming a protection against the entrance of water and dust into the carv upper panel, a lower panel, and an intermediate panel connecting the two, said upper and lower panels being provided with transversely extending corrugutions und with 0bliquely extending corrugntions, the transvereely extending corrugutions of the upper panel being disposed in alinexnent with the transversely extending eorrugutions of the lower panel, and the obliquely extending corrugations of the upper panel being disposed in nlinenient with theololquely eX- tending eorrugzltione of the lower panel, and the intermediate panel being provided with u longitudinally extending eorrgzttion tel i lninzlting adjacent its extremities ind adapted to receive moments transn'ntted by the corrugatlons ot the upper mid lower panels.

In testimony lwhereof I hereunto ntiix my signature in the presence of vtwo Witnesses,

this eighth day of January, 1913.
