8 Claims.

The invention relates to railway cars and more particularly to vertical walls for box or other house cars or open top railway cars, suc as hopper cars and gondola cars.

The invention is particluarly adaptable for use in side walls of railway'ca'rs, which walls perform two functions; first, they are the load retaining means, and secondly, theyare girders or trusses carrying the major portion of the weight of. the" lading. to the body bolsters from whence it is transferred to the trucks.

An object of the invention is to provide a very light and strong car wall which may be quickly and economically. made, installed and repaired and wherein the wall plates thereof may be made indies on reciprocating presses.

Such walls must be verylight, as it is expensive totransport dead weight in a car. and such walls must be very strong tocarry the vertical load as girdersv or trusses and also to resist the horizontal thrust of plastic lading, such as grain, etc., orof ashifting load. Theparts of the wall I must be capable of easy assemblage, because replacements frequently are necessary on account of wearing out of parts, corrosion and wrecks.

Another object of the invention is to provide a car wall so that the component parts thereof may be secured together by either bolting riveting or welding.

In the drawings: I v

Fig. 1 is a typical application of my device to the side Wall of a railway box car.

Fig. 2 is a section on line 22 of Fig. 1.

Fig. 3 is a section online 3-3 of Fig. 1.

Figs. 4, 5 and 6 show the relation between the side plate and junction of adjacent side wall sheets.

Fig. '7 is a horizontal. cross section through a modified construction.

In the form of invention illustrated the upper frame member 2 and the lower frame member 4 may be considered as a side plate and side sill, respectively, of a railway box or house car, or may be considered as atop reinforcing member and side sill, respectively, of a gondola, hopper. or other open top car. In either event, they are the upper and lower chords, respectively, of the wall when considered as a girder or truss. The wall plates form the web of the girder and the panels hereinafter described are the stiffeners of the web plate, or when considered as a truss, the panels form the compression members and the plates themselves form the tension members.

In the preferred form the wall comprises a plurality of wall plates with their adjacent margins secured together and extending between the upper and lower frame members. These wall plates are secured to the inner side of the upper frame member 2 and to the outer side of the lower frame member 4 to form a shingle construction.

In the preferred form each of said wall plates is provided with an outwardly projecting panel 6 adjacent each of its vertical margins which extend from adjacent the lower part of the upper frame member 2 to and beyond the upper part of the lower frame member 4. Each wall plate is also provided with an inwardly projecting panel 3 preferably extending continuous: ly between the outwardly projecting panels 6 which extend from adjacent the upper part of the lower frame member 4 to and beyond the lower part of the upper frame member 2. The overlapping of the outwardly projecting panels 6 upon the lower frame'members 4 strengthens the end of the beam-column at line 1010 and the overlapping of the inwardly projecting panel 8 upon the upper frame member 2 strengthens the beam-column at line 12-42. The adjacent inner and outer panels preferably merge into each other, as shown in Fig.7.

The. plate is secured to the upper frame member .2 by rivets 20 in the flat marginal portion of jtherplate in alignment with the side marginal panel 6. The plate is also secured to the upper frame member 2 by the rivets 22 in the marginal portion 'of the plate in alignment with the central panel 8. The wall plate is secured to the lower frame member 4 in a similar manner. An additional row of rivets (24) are desirable.

1 .The total width of the two side marginal panels 6 is preferably substantially equal to the width of the central panel 8 when the panels are of equal depth so that the neutral axis of the paneled plate will be midway between the bounding planes of the side and central panels soas to develop the maximum strength of the metallic plate as a vertical beam. (See'Fig. 7 wherein 26 plus 28 equals 30).

The wall plate is provided with a flange 32 at one vertical side thereof, which flange is preferably provided with a re-flange 34. to stiffen the flange 32 against buckling. If an interior lining is desired a nailing strip 36 is secured to the flange by the bolt 38 and the lining 40 is nailed to this nailing strip. With this arrangement the bolt does not extend to the outside of the car, thus eliminating a possible leak. The lining is preferably spaced away from the central panel at 42 to prevent sweating of the plate; to allow the plate to dry to prevent corrosion; to giveroom for grain to fall down to the floor and to allow compressed air to be blown between the plate and the lining for cleaning. Numeral 44 is the floor.

' Theaccompanying drawings illustrate the preferred form of the invention, though 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, within the scope of the claims, will occur to persons skilled in the art. v
