To allwhom'itma concern.

Be it known t at I, GLAUS' J. WERNER America, and resident of Davenport, Scott county, Iowa, have lnvented a certain new and useful Improvement in Railway-Car Construction, of which the following is a specification.

My invention relates to railway-cars-and has particular reference to the frame-work and metal sheeting forming the supers'truc- A ture of an all steel box car, and is directed more particularly to the method of securing,v

the sheets, forming the sides of the car superstructure, to the framing members, whereby a flexibility is elfected, at the connection of the sheet to the framing members, to a debuckling strains in the side sheets due to the deflection of the car sides under heavy. load and thus make'possible the successful use of unusually light "or thin sheets in the.

make up of the envelop or superstructure of the car.-

In a ea? in which the superstructure framing, consisting of vertical posts diago nal braces connected at their lower ends with the side sills of the underframe-and at their f upper ends to the top side-plate, together with the side sheets, form deep girders supported at the body bolster, they can be and are utilized as the principal load carrying members. When a load is imposed upon a girder of this character and which is sup- V tions of s1de sheets, arranged 1n panels thesheets from their original rectangular form to that of a parallelogram or trapezoid and thereby cause them to wrinkle or buckle. Int the interest of low costof production and the avoidance of dead weight (the constant transportation of which is one of the greatest items of non-productive expense incident to practical railroading) sheets of.

sufficient strength and thickness to withstand these buckling strains cannot be employed. My invention is thereforedirected to .providing means whereby the development of these buckling strains is prevented,

thus making possible the use of sheets of unusually light gage.

It also consists in providing a' frame- Specification of Letters Patent.

somewhat exaggerated view of the joint or connection between the marginal flanges of two sheets, viewing same from the interiorof the car.

Fig. III is an enlarged sectional View of this joint at the upper end of Fig. II and Fig, IVv is a similar View of the lower-end of"Fig. II;-'

i Similar reference numerals represent similar parts throughout theseveral views.

. As the underframe of the carforms no part of my present invention, further refer-. ence, thereto is deemed unnecessary other.

than to say it is to be equipped with the 'usualside sill to which my improved car side is to be attached. This is equally true of the roof, as my car side is designed to be -.used in connection with roofs generally used.

The vertical posts 1 and the diagonal braces 2 are preferably .made of Z bars which may be described asa bar having op tral axis thereof. By perforating the web of'the 2 bars with rivet holes near its neutral axis, practically the entire strength of the original bar is preserved.

It will be noted by reference to Figs. III

and IV that in placing the sheets in position the flanges of adjacent sheets are brought in direct contact with each other and both positioned on the same side of the 2 bar web to which they are riveted. The rivets are placed nearer the outside edge of the flanges, forming an absolutely tight joint at these'edges. The distance from the center of the rivet in the flange to the body of the sheet can be greater than the distanc'e from the center of the rivet to the free edge of flange. This length of flange from the rivet to the body of the sheet can.

be such as to permit of a slight separation of the flangeswhen the entire side structure issubjected to deflection through heavy load, allowing the seam to gap as at% at .the inside and still maintain a weathertight seal at the outside. Thus it is that a degree of flexibility is effected at thejoint between the sheets and the posts'that prevents the.

accumulation of distorting or buckling strains. As seen in Fig. II with the car 4 side slightly deflected under load, the seam would be closed at the upperend of the sheet and gapped or opened at the bottom to an extent as determined by the amountof deflection of the girder formed by the car side.

Thus it is that through this flexible joint the use of excessively heayy and stiff sheets, capable of themselves resisting these buckling strains, is avoided and'the use of -unusually light sheets is made possible. This method of securing theflanges of the sheets to the web of the posts greatly facilitates the constructionof the car-as the entire rivet is exterior of the car where it is more readily riveted and by much simpler ap-' pliances than if the'rivet passed through the side of thecar by riveting the sheet to the flange of the Z bar post.

What I claim as new is: 1. In a railway box .car, the combination of the car sides including a'plurality of vertically disposed posts of Z bar section, me-y tallic sheets having their vertical edges flanged, said flanges being connected to the web of said vertical posts at or about the neutral axis thereof,

'2. In a railway box car, the combination of the car sides including a plurality of parallelv vertically disposed posts, having op-' positely extending flanges and a connecting :web, metallic sheets having their vertical" edges flanged connecting said posts at their webs, the flanges of adjacent sheets abutting -each other and positioned on the same side of the post web 'to. which they are connected.

3. In a railway box car,-the combination of a steel frame-work for-the superstruc--- ture thereof, including vertically disposed posts having oppositely'exte'nding flanges and a connecting weband abutting flanged sheets, expansively connecting the webs of Said vertical posts.

4. In a car side formed of rectangular.

metallic plates having their vertical edges flanged, vertical posts having oppositely exrectangular metallic sheets with flanged ver- *tical edges connecting said posts at or about the neutral axis thereof, the flanges of adjacent sheets abutting each other and connected on a'vertical line nearer the free edge of said flanges thanthe body of. the sheet whereby that portion of the'opposing faces of the flanges between the body of the sheet and the line of connection are capable of receding from i and approaching, one another when said sheets are under strain.
