SHEET-STEEL OAR END.

Application filed March 29, 1915, Serial No. 17,840. Renewed July 18, 1919.

T 0 all whom it may concern:

Be it known that I, VINroN E. SIssoN, a citizen of the United States, residin' at Chicago, in the county of Cook and tate of Illinois, have invented certain new and useful Improvements in Sheet Steel Car Ends, of which the following is a specification.

My invention relates to an end structure for railway box cars, and its principal ob ject is to provide a sheet metal end structure of novel and improved design and construction in which the metal end sheet or sheets are provided with strengthening ribs or corrugations which extend vertically substantially from top to bottom of the car.

A further object is to provide a sheet metal car end so constructed that when applied to a box car the usual end plates may be dispensed with.

A further object is to construct the car end having vertically extending corrugations in such manner that the lower portion of the structure is stronger and more capable of resisting thrusts and pressures than the upper part. The advantage of this arrangement is that the structure may be thereby lightened without diminishing its effective strength so far as cargo thrusts are concerned. The end of a railway box car is likely to be subjected to very severe stresses due to the tendency of the cargo to shift, due to inertia, when the train starts and stops. Inertia thrusts of this sort are much more likely to be against the lower part of the structure than against the upper part since heavy articles likely to move longitudinally, such as rails, piping, or the like, are usually placed in the bottom of the car.

The invention has for further objects such other new and improved constructions, arrangements and devices relating to sheet metal end structures for railway cars as will be hereinafter described and claimed.

The invention is illustrated, in certain preferred embodiments, in the accompanying drawings wherein- Figure 1 is an elevation of the end of the superstructure of a box car constructed in accordance with my invention.

Figs. 2 and 3 are sectional plans on lines 22 and 3-3 of Fig. 1.

Fig. 4 is a vertical section on line 4-4. of Fig. 1.

Specification of Letters Patent.

Patented Nov. 16, 192d.

Serial No. 311,907.

Fig. 5 is a plan view of the end of the car with the roof boards removed.

F ig. 6 is a vertical sectional view on line 66 of Fig. 5.

Like characters of reference designate like parts in the several figures of the drawings.

Referring to the drawings, 10 indicates one of the end sills of a railway box car, 11, 11 the corresponding corner posts, which are shown as angular in cross section, 12, 12 the side sills,and 13, 13 the side plates which are shown as angle bars. The end structure comprises, in this embodiment of the invention, a panel consisting of metal end sheets 14, 15 which extend from top to bottom of the car and are secured together at their meeting edges. The sheets are formed with vertical corrugations 16 which terminate within the edges of the sheets, the latter preferably extending substantially from the floor of the car to the roof. The sheet 14 has a flat, marginal portion 17 which extends back of the edge corrugation 16 of sheet 15 and is secured thereto by two lines of rivets '18. The outer edges of the sheets are secured to the corner posts 11 by rivets 20. The lower edges of the sheets are riveted to the end sill 10. The upper portions of the sheets are preferably bent over on lines diagonal to the edges of the sheets so as to provide flanges 21 for supporting the roof of the car. For ex ample, the purlins 22 of the roof structure may be riveted to flanges 21.. The inner ends of the flanges 21 are preferably joined by a gusset plate 23 which provides a support for the ridge pole 241-. The outer ends of the flanges are riveted to the side plates 13. Preferably the connection is made more secure by means of gusset plates 25. In order to further rigidify and strengthen the upper part of the end structure and the adjoining portion of the roof a structural steel beam, for example a channel bar 26, extends across the car from side to side. The bar is bent at the middle to correspond with the slope of the roof and its ends are sheared ed as indicated at 27 (Fig. 6) and rest upon the side plates 13. One of the bolts 28, which secure the ridge pole 24: to thegussetplate23,preferablyextendsthrough the channel bar 26, the outer leg of which is riveted to the panels 14, 15. In order to check weaving strains T preferably connect the flanges 21. on the end sheets with the side plates 13 by diagonally extending braces 31 which may be secured to the intervening purlins.

' It will be seen that the flanges 21 serve the purpose of the ordinary end plates.

-This is feasible because by forming the end sheets with vertical corrugations they become capable of carrying a part of the weight of the roof, the corrugations 16 acting as a series of posts.

The corrugations .16 are made deepest along a line below the center of the car. From this place the corrugations taper toward their extremities as shown. By making the corugations deepest along a line below the center of the end structure the lower portion is strenghtened, as against cargo thrusts, at the expense, of course, of the upper portion of the structure. The weakening of the upper portion, however, may not in all cases be important as, for the reasons stated, the upper part oi the end of a railway car is not subjected to the heavy cargo thrusts which the lower part has to withstand.

I claim:

1 In a box car, an end structure comprising two metal end sheets each extending from top to bottom of the car, secured together along their meeting edges, and formed with corrugations of varying lengths which extend from approximately the floor of the car to: within a short distance of the roof thereof and terminate within the edges of said sheets, the inner lateral edge of one of said sheets extending back of the adjacent corrugation of the other sheet and being secured to said other sheet by lines of rivets on both sides of said corrugation, said corrugations having their greatest cross sectional area along a line below the center of the end structure and above the floor and being of diminished cross sectional area above and below said line.

2. The combination with a box car, of an end structure for the same comprising a pair of metal sheets extending from top to bot tom of the car and overlapped at the center thereof, the overlapping portion of one of said sheets being provided with a vertical corrugation which extends substantially from top to bottom of the sheet, terminates within the edges thereof, and has its greatest cross sectional area at a point below the center of the end structure and above the floor, said overlapping portions being secured together on opposite sides of said corrugation, said end structure being provided at the top of said overlapped portion with an inwardly protruding rigidly fixed metal plate to which said ridge pole is rigidly secured.

3. In a box car, an end structure comprising two metal sheets each extending from top to bottom of the car secured together along their meeting edges, and termed with corrugations which extend from approximately the iioor of the car to within a short distance of the roof thereof, the inner lateral edge of one of said sheet-s extending back of the adjacent corrugation oi the other sheet and being secured to said other sheet by lines oi rivets on both sides of said corrugation, said corrugations having their greatest cross-sectional area along a line below the center of the end structure and above the floor and being of diminished cross-sectional area above and below said line.

l. The combination with a box car, of an end structure for the same, comprising sheets extending from top to bottom of the car and overlapped at the center thereof, the overlapping portion of one of said. sheets being provided with a vertical corrugation which extends -from approximately the floor of the car to withina short distance of the roof thereof, and having its greatest crosssectional area at a point below the center of the end structure and above the floor, said overlapping portions being secured together on opposite sides of said corrugation, the overlapped portion of said sheets being provided witlr attaching means adapted to be rigidly secured to the ridge pole of the car.
