Application filed December 24, 1915. Serial No. 68,587.

To all whom it may concern.

Be it known that I, ALLEN E. OSTRANDER, residing at Ridgewood, Bergen county, New Jersey, and being a citizen of the United States, have invented certain new and useful Improvements in Corrugated-Sheet-Metal Cars, of which the following'is afull, clear, and exact description, such as will enable others skilled in the art to which it appertains to make; and to use the same, reference being had to the accompanying drawings,

which illustrate the preferred form of the invention thought 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 modifications thereof will occur to persons skilled in the art.

In said drawings:

Figure, 1 is a side elevation of approximately one half the car, a portion being broken away to show the inside sheet.

Fig. 2 is an enlarged substantially half transverse section, taken on line 2-2 of Fig. 1, an intermediate portion being omitted.

Fig. 3 is an enlarged central longitudinal section of an end portion of the car taken on line 3'3 of Fig. 2, with an intermediate portion omitted, and

Fig. 4 is an enlarged horizontal section taken along line 44 of Fig. 1, intermediate portions being omitted.

a It is the object of the present invention to provide a construction for cars, and particularly that type known as box cars, which shall have :a superstructure which renders the use of the usual side and end framing, carlines and purlins unnecessary;

' By virtue of the properties of corrugated sheets and the proper arrangement and as sociation of a plurality of them, the sideand end walls and the roof possess inherent selfsustaining qualities, and result in'a car having a minimum number of parts.

- Another object is the incorparation of side and end sills inthe side and end walls of the car, or of the end' sills in the end walls alone, or of the side sills in said side walls alone, with independent structural sills substituted where the incorporation does not occur.

Still another object is the prevention of rain or s entering t een t e associ ted sheets and the consequent lessening of their.

lives due to ferrous disintegration. Referring now to the drawings, 1 indicates parallel channels, of a length substantially equal to the car length, and disposed on each side of the longitudinal center line of the car, said channels constituting the center sills. The end portions thereof in conjunction with draft sill extensions 2 form the draft sills.

Said draft sill extensions 2 are attached to the channels 1 and are in-the form of channel pressings Which extend under and project outside of the end walls of the car and assist in supporting striking plate castings 3. -Draft sill extensions 2 also cooperate with said striking plate castings and carry irons 3 in positioning and supporting the coupler shank (not shown).

As shown in Figs. 1 and 1, the usual bolsters A, floor beamsB- and cross bearers C are disposed transversely of the center sills 1, and at their outer extremities support side sills 4, here shown as channels. Transversely disposed end sills, to be later described, connect theends of said side sills.

Each side wall of the superstructure comprises a plurality of conterminous corrugated metal sheets, preferably a pair, the arches and furrows of the outside sheet 5 being vertically arranged, while those of the inside sheet 6 have a horizontal disposition. The vertical corrugations of sheet 5 resist flexure ofsheets 5 and 6 from the vertical, fiexure of said sheets in a horizontal direction being opposed by the horizontal corrugations of sheet 6.

The furrows of sheets 5 and 6 contact at regular intervals, and some of the points of contact'of said furrowsareelectrically or otherwise welded. These welds 7 are usually Each end wall is similarly constructed, having an outside sheet 8 and inside sheet 9, both being corrugated and conterminous, with the corrugations arranged as in the side walls, and said end walls have all the properties and advantages of the side Walls.

A roof, preferably, but not necessarily, a ch d, i ik i e const c d of conte mim ous corrugated sheets, the corrugations of 'inside sheets 6 contact with the furrows of outside sheet 5, and rivets 13 pass through the metal of the furrows of sheets 5, the

. lower uncorrugated portions'of sheets 6 and the websof side sill channels 4, securing them together. portion of each inside-sheet 6 also contacts with the furrows of its associated outside sheet 5, and rivets 14 pass through both said sheets and the internal side plate ,12, binding these elements in permanent relationship.

In each end wall, the corrugations of in side sheet 9 do not extend below the floor line, nor above the bottom of the internal top chord 19 of the end sill. Outside of the end plate 15. The outside sheet 8, inside sheet 9 and the end plate 15 are fastened to each other by rivets 16.

It is well within my conception to arrange the side and end sills, as well as the side and end plate, on the exterior of the side and end walls in instances where it is advantageous to do so. No limitation is, therefore, to be construed by the reference to these parts which designates them as internal members.

Along the lower horizontal edge of sheet- 9 of each end walliis secured thereto and to sheet 8, by rivets 17, an angle 18, and

parallel therewith but spaced above said angle is another similar angle 19, also secured to said sheets 8 and 9 by rivets 20-. Angle 19 is the top chord and anglei18 the bottom chord of the end sill, and the lower portions of sheets 8 and 9 constitute theweb of said sill. Obviously, such a construction may be substituted for the side sill channels 4, if desired.

Said end sills and the side sills 4 are joined at the corners formed by their meet.

ing'ends by flanged gussets 21.

I Rivets 13 bind one flange of each gusset plate 21 to the side sills 4, while rivets 20 secure another gusset flange to the angle vertical end edge portions of the side and end walls. are vertical angle corner posts 22, extending from the bottom of said walls to the top thereof. Said walls are secured to each outside corner post by means of rivets 23 passing through one flange of the corner post and sheets 5 and 6 of the side wall, and

The upper uncorrugatedthrough flange of gusset 21.

floor stringers 31, preferably commercial 1 are wooden floor stringers or nailing strips also by other rivets 24 passing through the other flange of said corner post and sheets i 8 and 9 of the end wall.

The inside faces of the vertical endpedge portions of the side and end walls are joined by connection angles'25, a vertical llIlB Of by their arches and furrows, and one flange of the connection angle 25 associated with each corner post, and another vertical row of. bolts 27 passes through the other flange of each of said outside corner posts, similarly channeled portions of sheets 8 and 9, and the other flange of said interior connection angles 25. Thus, the vertical end edges of the side and end walls -are embraced by or pocketed between said corner posts and corner connection angles and riveted to the first andclamped between both.

The corner posts 22 are each connected at their lower extremities to the ends of the side sills by the two lowest of the rivets 23 and by rivets 28 which pass through one flange of said corner post 22, sheets 5 and 6 of the side wall and the web of the side sill channel 4, and to the ends of the end sills. by the two lowest of the rivets 24 "and by V rivets 29. r r

The rivets 24 which'secure the end walllapping flange of each of the posts to the end sills may be countersunk because of the push pole pocket casting bearing against said flange and said rivets 24 pass through said flange, sheets 8 and; 9 of said end .wall and the vertical flanges -of-the top and bottom chord angles, 19 and 18 of the end sill. One rivet 24 {passes Rivets 29 pass through a flange of .said push pole pocket casting and the other parts v j ust .f enumerated.

In the underframe, the center and draft sill channels 1 are attached tonthe end sillfajo by angular connection plates- 30, crimpedu to fit said end sill. See Figs. 2 and 3. Inter- -mediate the center and draft sill channels 1' and the side sill channels 4 are longitudinal Z-bars, connected to said end sills by angular connection plates 32 crimped tofit said 3 I sills.

Resting on the top flanges of the channels 33 and supported upon said wooden string.- ers 33, Z-bar stringers 31 and the top flanges of side sill channels 4 is a suitable floor 34. The bottom corrugations of the inner sheets of the side and end wallsbear on top of floor 34 and hold it downonthe" top flanges of the 'side and end sills. A beveled grain strip 35 runs about the boundary of the floor in the angles formed by said floor and the side and end walls, wherebywhen the lading is grain, for example, it will not be able to accumulate and remain in the floor corners of the car.

Diagonal braces, running from the corners of the underframe to the center sills, are

present in the form of angles 36 attached to v gussets 21 and to said center sills l, the con jointsbetween the side. walls and the roof throughout the length of the car.

Internal end plates 15 are also flanged at the top, the flanges 40- extending outavardly and abutting the downwardly directed flanges 41 of. roof sheet 10, said flanges 40 and 41 closing all air passages at purpose.

the top of the end walls that would otherwise lead to the interior of the car. End plate flanges 40 also support the ends ofthe roof sheets 10 and 11. v

On top of the roof is mounted a running board 42 supported upon running board saddles 43, bolts passing through the said running board 42, saddles 43, and roof sheets 10 and 11, binding these elements together. The overhanging ends of the running board are tied together by cleats and braced to the end walls by brace rods 44.

Sheets 5 of the side walls are flanged, as at 45, to close'the arches and furrows of its companion sheet, and sheets 8 of the end walls are likewise flanged at 46 for a similar See Fig. 4.

' In general, tight oints between the Walls, the roof and floor are provided and the ducts formed by the arches and furrows of the wall and'roof'sheets are closed, so that the interior of the car is impervious .to the weather, as are also the internalsurfaces of the corrugated sheets comprising thewalls of the car.

' The car may readily be converted into the ventilated type that is used for transporting perishable lading by.,simply preventing the contacting of flanges 37 of the side plates with roof sheets 11, or by leaving spaces between] the downturned flanges 41 of ,roof' sheet :10 and thejuxtaposed edges of flanges -l0 of end plates 15. Also, the car may be ventilated in both manners. To guard against any possible spreading of the walls under the influence of such ladi-ng as grain the tops of the side walls are restrained from outward deflection by tie rods or angles 47 illustrated in Fig. 2 as being connected to said side walls by angular connection plates 48.

' When there are to be door openings in the car, the walls, as for example, the side walls, art interrupted to form such door openings and the inner vertical edge portions'of the side wall sections are attached to a vertical flange of a door post, the latter being a,

pressing 49 of J-shaped cross section from which said door post flange extends. Vertical strips 50 are disposed against the inner ends of sheets 6 of the side walls opposite theflanges of the door posts 49, and a vertical line of rivets passes through each strip 50, sheets 6 and 5 of the side Wall and said flange of the door post 49, binding them to gether and pocketing the side wall between the doo-rpost flanges and strips 50.

\Vithin pressing 49 is a wooden filler 51, and against it is placed a wooden nailing strip 52 to which a grain door may beprovided in the form of angles 55 riveted to the outer faces of the webs of the side sill channels 4.

Push pole pocket castings 56 are securedto the lower corners of the end walls, and both said push pole pocket castings and the striking plate castings'are provided with integral ribs 58 having cylindrical bosses, which occupy positions in the furrows of sheets 8 and interlock said castings with the end walls of the car, restraining them from displacement, and further spaces themin advance of sheets 8 so that'pre'ssure exerted against said castings will not injure said sheets.
