Application inea october i7, 1917', serial no. 197,107. Renewed may 31,1921. serial No. 473,779.`

My invention relates to railway cars, particularly cars of the gondola type although 'I0 applicable to other types of cars, and has for lits object to providea new and improved car end structure ,which will be inexpensive to manufacture .and which will have the necessary strength and rigidity to withstand the various stresses to which car ends-are subjected when in service. IWhere the contents of a car consist of 'material in bulk, such as coal or crushed stone, for example, the greatest stress imposed on the car end is in the region of the lower half` of the end. This portion of the car end is also subjected to severe stresses incident to the cargo thrust ydiie to the sudden starting or stopping of the car, particularly when the cargo consist's of heavy movable objects such as railroad rails or car wheels.` Accordingly it is an object of my invention to provide a car end structure which is so formed and reinforced as to be strongest in the region of greatest stress. My invention also conteinplates the'provision of a suitable lining which rooperates with the other elements ofthe end structure so as to reinforce the same.

My invention consists in the novel arrangement, construction and combination of parts hereinafter. described and claimed for carrying out the above stated objects and such other incidental objects as will appear from the following description.

My invention is illustrated, in certain preferred embodiments, in the-accompanying drawings, wherein Fig. 1 is an elevation of my end structure applied to a gondola car.

E. SissoN, a

Fig. 9 is a horizontal section on line 9---9 of Fig. 7, and Fig 10 is a sect-ion similar to that shown iii/Fig. 9 showing a modified form of end pos i i Like characters of reference indicate like n parts in the several figures of the drawings.

f Considering first Figs. 1 to`3vi13lusive, of the drawings, l is an end ariel consisting, in .the embodiment of the invention shown, of a single sheet having a'series of horizontally disposed corrugations 2 yrunning vfrom edge to 'edge of the sheet. l. The corrugations preferably increase .in depth uniformly from` y the top to the bottom of the sheet, as shown at 3 1n Fig, 2, so'asto provide the greatest kstrength at the lower part of the end. The

upper edge .of the sheet is. bent inwardly to provide a horizontal flange 4 which is riveted to an angular end plate reinforcing member 5 whichfrun's across the top of the car. The ends of said reinforcing member are preferably bent at the corners of the carP and secured to the sidewalls thereof. `T he vertical edges of the sheet aresecured to the car body between pairs of angular attaching members 6 and 7. Asshown. in Fig. 3these attaching members are provided with flanges 8 and4 9 which are rivetedto opposite faces of the side sheet or to the carbody, as the case may be. The margins of the end sheet extend between the attaching members and for this purpose the inner attaching members are inclined so as to contact with the inner portions of each corrugation. The attaching members are preferably riveted to thev end sheet at several points of contact, that is, at 4the corrugations. as shown, so as to provide, in effect, a restrained'beam. The lower portion of the end sheet is provided with a flatmargin 10 which is riveted to lthe Z-bar `end sill 11, as shown in Figs. 1 and 2. 'y

ln this' construction' I have shown'the end provided with a wooden lining consisting of boards 12 extending at rightangles to the corrugations 2. The upper ends of the boards extend back-of the angular reinforcing member 5 and the lower ends of said boards fit into a groove `provi-ded between the flooring 13 and the vertical 'flange 14 of the Z-bar 11. lIf desired, the lining may be further secured to the end sheet by ifneans` of bolts 15')` `which pass'tlirough the filler blocks 16 and end sheet 2. It will A sured against leakage betweenthe corrugated edges and the attaching members, and is also reinforced in a manner to prevent the corrugations from spreading, intermediate their ends, under strains due to the cargo thrusts. It will also be noted that the lower edge of the lining bearing against the Z-bar end'sill will transmit a certain por tion of the stress due to cargo thrusts directly to the end sill. 17, 17 designate the draft sills of the car which are preferably channel-shaped in cross-.section and are riveted to the horizontal web 18 and downwardly projecting flange 19 vof the Z-bar 11. The coupler 20 may be supported in any suitable manner between the draft sills, for example, by means of the metal stripor coupler carrier iron 21 secured to the lower horizontal Hanges of the draft sills.

In Figs. 4, 5 and 6, I have shown a modified form of end construction in which the outer attaching members 22 are corrugated so as to fit thecorrugations in the end sheetV 24. VIn this modification the outer attaching members 22 are provided with flanges 25 secured to the car sidesI 26 in much the same manner as shown in Figs. 1, 2 and 3. The other portions of the members 22 overlap the side margins of the end sheet at 27 and, as stated, are corrugated. to fit the corrugations 28. The end sheet and attaching members are preferably riveted at each corrugation by rivets 29. The inner attaching members 30 are secured to the inner face of the l side sheet, as shown in Fig. 6. These attaching members may be made either straight, contacting with the end sheet only at the inmost points of the corrugations, or they may, if desired, be corrugated as in the case of the outer attaching members. The end sheet 24 is secured to the car body along its upper and lower edges in the same manner as shown in Figs. 1, 2 and The lower end of the inner attaching members 30 are preferably secured to the side sills 31 by means ofthe gussets 32. In this construction it will ordinarily be unnecessary to usevalining to prevent leakage between the ends of the corrugations and the attaching members as all joints are tightly closed by means of the corrugationsl in the attaching member.. It will be obvious, however, that this construction could be reinforced, if desired, by the use of a lining substantially the same as that illustrated in Figs. 1, 2 and 3. I do not make specific claim herein to the form of the invention shown in Figs. 4, 5 and 6 as this Imodification forms the subject matter of a divisional application filed June 9, 1922, Serial No. 567,019.

In the modification shown in Figs. 7 to 10 inclusive, the ends of the corrugations in the end sheet 33 terminate within the edges of the sheet, thus leaving a lflat margin 34 along. the vertical edges of the sheet. The marginal portions are preferably bentat right angles to the body of the sheet to provide angular attaching flanges 35 which are securedto the corner posts 36. In this construction I also preferably provide angular attaching and stiffening members 37, the flanges 38 of which arel secured to the corner posts.I It will be seen from Fig. 8 that in this construction the corrugations, increasing uniformly in depth, extend outwardly from the plane of the car end. i Accordingly the attaching members 37 must be constructed with. the flanges 38 wider at the bottom than at the top in order to properly secure the margins of the end sheet to the'car.

The lower edge of the sheet is riveted to the end sill'40 which, in turn, is secured to the side sills 41 and draft sills (not shown) in any suitable manner. The upper edge of the end sheet is provided with a horizontal flange 42 extending across the top of the car and secured thereto.

In the modification showni in Fig. 10, I

use a modified form of corner post 43. This is in the nature of a gusset stay which extends to the height of the car sideand is riveted to the end sheet and to the side sheet and attaching flanges.

In'the modifications shown in Figs. 7 to 10, leakage is prevented by the flat margins extending along the sides and bottom of the sheet in a lmanner to provide a tight joint vbetween the sheet and the car sides and' bottom. The construction shown in Figs. 7 to 1G, inclusive, is not claimed specifically herein as it is the subject matter of a divisional application filed'April 18, 1921, Serial No. 462,147.

In the drawings I have shown an end sheet in which the corrugations merge one into the other and increase in depth fromthe top to the bottom; This is for the purpose of increasing the strength of the end sheet at the bottom, or near the bottom, where vthe greatest stress is imposed due to cargo 4thrusts caused by' shifting of the contents of the car, and also due to internal pressure which is in the nature of a hydrostatic pressure'formed by contents of the car which are not self sustaining as, for instance, coal or ore.
