Appljcation filed November 21, 1917. Serial No. 203,132.

To all whom it may concern:

Be it known that I, ViNToN E. SIssoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Railway-Car Construction, of which the following is a specifieation.

My invention relates to the construction of railway cars, more particularly. box cars; and the primary object of the invention is to provide a sheet metal wall structure more particularly for the end of a railway car comprising one or more sheets formed with corrugations which run to the edges of the sheet, together with novel means for securing said sheet or sheets to the frame of the car, whereby a wall structure is formed which will be very strongand well adapted to resist cargo thrusts, and which, when employed at the end of the car, will rigidify this part of the car, and, in fact, the entire superstructure of the car, against weaving and other like strains. A further object is to provide a car wall construction which can be inexpensively manufactured and readily applied either to new cars or to the repair of old cars.

The invention consists in the novel c0nstructions and arrangements to be hereinafter described and claimed for carrying out the above stated objects and such other incidental objects as will appear from the following description.

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

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

Referring first to Figs. 1, 2 and 3, the end construction herein shown employs a sheet metal end panel 25 consisting of a single sheet of metal extending across the car from side to side and from top to bottom, formed with projecting corrugations 26 which run to the upper and lower edges of the sheet. In this construction the end sill of the car consists of a Z-bar 27, the upper horizontal flange 28 of which supports the floor boards 29 of a car, while the lower horizontal flange 30 supports the end panel 25,the lower edge of which is secured to the vertical web 31 of the Z-bar by means of rivets 32 arranged, preferably, between each of the corrugations. The end plate-33 is also a Z-bar and is bent novel form of end plate and means different to correspond with the slope of the roof. The lower vertical flange 34 of the Z-bar 33 overlaps the upper edge of the end panel and is riveted to the several corrugations thereof, as indicated at 35. The vertical edges of the end sheet are secured by rivets 36 to the angle bar corner posts 37. Regarding the corrugations as the ribs of the sheet which project outward from the car, it will be seen that each corrugation is riveted to a rigid member, the end plate 33, while the inwardly projecting ribs, that is, the portions of the sheet between the corrugations, are riveted to a rigid member, namely, the end sill, at the bottom of the car. The corrugations perform the function of beams, in respect to cargo thrusts orother stresses exerted against the end wall of the car. These thrusts-are transmitted to the end sill and end plate and the attachment of the sheet to these members is such that the corrugations function, in effect, as restrained beams.

The end plate is formed so that it extends over the upper edge of the end sheet so as to make a waterproof joint at this place. The lower edge of the sheet overlaps the end sill of the car below the floor level so that the construction at this point would probably be fairly tight without further precautions. However, in order to prevent leakage and insure perfect waterproofing at the bottom of the car, I preferably insert filling elements, wooden blocks 38 in the bottoms of the corrugations cementing them in place by any suitable cementitious material. In order to support theridge pole 39 and purlins 40 from the end plate an angle bar 41 is riveted to the end plate on which;

the ends of these elements rest. A. wooden fascia plate 42 may be supported on the end plate 33 so as to provide a nailing strip for the roof boards 43.

A sheet metal end panel, in which the corrugations run to the edges of the sheet may be manufactured more cheaply than a sheet metal wall element in which the corrugations terminate short of the edges. A sheet of the latter type has to be pressed hot and the peration involves the use of expensive apparatus. The loss of plates due to the rupturing of the metal and to warping, may be considerable if, as desirable, the corru gations are made deep. By having the corrugations extend to the edges of the sheet. the corrugating operation may be performed by a cold rolling process. The corrugations may be given any desired depth without involving'the thinning or stretching of the metal.

In the construction shown in Figs. 4 to 6 inclusive, attaching means for the upper and lower edges of the sheet is provided which increases the rigidity of the corrugations and their efficiency, considered as means for carrying the cargo thrust load to the upper and lower frame members. In this construction the corrugated end sheet 44 is seated on the horizontal web 45 of the Z-bar end sill 46. The web 45 is wider than the depth of the'corrugations, making place for the angle bar restraining strip 47 riveted to the end sill outside of the edge of the end sheet. The upper edge of the sheet is secured, as in the construction previously described, to a Z-bar end plate here designated 48. On the inside of the sheet is arranged an angular brace 49 riveted at 50 to the sheet between each corrugation thereof. The ends of the brace 49 are bent diagonally, as indicated at 51, and are again bent, as shown at 52, and secured by rivets 53 to the side plates 54 of the car. In this construction the car is provided with a wooden lining consisting of horizontally arranged boards 55.

In Figs. 7 to 10 inclusive, the panel consists of two vertically corrugated sheets 55,

55 the latter having a flat margin 56 extending back of the marginal corrugation 57 of sheet 55 and secured thereto by two rows of rivets 58. This arrangement provides the end with a stiffening element of the box girder type and also furnishes an effective means for waterproofing the same between the sheets. In this construction I have shown 1 the sheets as provided with flanges 59 on their outer vertical edges which take the place of the usual angular corner posts in cars of this general type. The lower edge of the sheets (not shownlmay be secured to the body of the car in any desired manner, for example, as in either of the two constructions previously described. The end plate shown in the construction of Figs. 7 to 10 is provided with a vertical flange 60 which overlaps and is secured to the upper edges of the sheets and with transverse flanges.61 having the slope of the roof, the latter flanges being preferably increased in width toward the sides of the car so that they have wide bearings on the side plates 62 of the car to which they are secured by rivets 63. An end plate of this construction aids in giving the framing of the car the rigidity necessary to withstand the tendency of the car toweave. In Fig. 11 the end sheet 64 is provided, for the purpose of giving added stiffness and strength, with an additional outwardly projecting flange 66.

In Figs. 12 to 16 inclusive, I have shown an end panel consisting of three corrugated end sheets. The middle sheet 67 is preferably of heavier gage metal than the side sheets 68. It is preferably secured to the side sheets so'as to provide two box girder reinforcements 69, 69. In thisv construction the upper edges of the sheets do not have the slope of the roof. The roof slope is taken care of by providing a Z-bar end plate 70 which is of greater height and least width adjacent the middle and diminishes in height and increases in width toward the sides of the car. end plate is a T-iron 71 having a flange 72 to which the inwardly projecting ribs of the end sheets are secured. The upper vertical flange of the T-iron 71 may be cut away near the side of the car to clear the horizontal web of the Z-bar end plate 70. Attached to the horizontal flange 73 of the T-iron are a pair of braces 74 which inter? sect and are riveted together at 75 and have their extremities secured to the'side plates 7 6 of the car, as shown in Fig. 16.

A construction, modified so far as the end plate is concerned, is shown in Figs. 17 to 19 inclusive. The end plate here provided is made by splitting the vertical web 77 of an I-beam and expanding the I-beam so that it has the gable shape necessary to give proper slope to the roof of a car. The opening 78 in the I-beam is covered by a wooden fascia plate 79. The metal roof sheets 80 at the end of the car are bent at 81 to engage the upper flange 82 of the I-beam. The end sheet or sheets 83 are secured to the end plate bymeans of a pair of angle bars 84, 85. The vertical flange 86 of the angle 84 preferably extends around the corner and is secured to the side plate 54. The angle 85 may be secured to the side plate in any suitable manner, for example, by means'of the angular gusset 87.

In Figs. 20 to 22, inclusive, I have shown another modification in the means for attaching the end sheet to the car frame. In these figures the sheet 87 is formed with angularly disposed flanges 88 suitable for attaching the vertical edges of the sheet to the side wall of the car. At the lower edge of the sheet 87, metal strips 89, 9O traverse the corrugations and are secured at their points of contact to the inner and outer surfaces of the end. sheet, the ends of the strips being secured to the side sills 91, 91. This construction makes the usual end sill unnecessary. The lower edge of the end sheet and the metal strips 89, 90 will function as a restrained beam extending from side to side of the car and will be sufficiently rigid 'to withstand the stresses to which car end sills are subjected. The lower ends of the corrugations are preferably closed by means of filler blocks 92. Metal strips 93, 94, are riveted to the sheet 87 near the upper edge thereof. The ends of these metal strips are riveted to opposite faces of the vertical side plates 95, or

otherwise suitably secured to the side of the car. This construction, it will be noted, provides a restrained beam adjacent the roof of the car. The numerals 96 designate the draft sills, the upper flange 97 of which is riveted to the lower edge of the end sheet and to the metal strip 89, as indicated at 98 Secured to the back of the I claim:
