At the present time there are many thousands Stillanother specic object of theinvention is of wood sheathed box cars owned by various to provide a converted car of thetypeabove in- 5 railroads, which box cars where built several dicated wherein the metal sheathingA replacing 5` years ago.

Referring to Figure 6, the box car prior to conversion, is shown as having the usual outer Wood sheathing 23 extended down below the floor H9 beneath which is disposed a Wood stringer 24 supported at longitudinally separated intervals by short angle irons 25 riveted to the side sill l l l, the lower ends of the outer sheathing boards being retained by a 'longitudinally'extendingangle 26 bolted through the sheathing boards, stringer 24 and side sill l i I.

In making the conversion to the steelshea'th-i ing, the outer sheathing boards V23and angles 2S, stringers 24 and angles 25 are not only taken off but discarded. Temporarily, also, 'the 'corner post i8 is taken out as Well as the inner lining Zal but are later replaced and used as shown in Figures 1 to 5.

In carrying out the invention, the sheet metal,V preferably steel, outer sheathing. designated generally by the reference character A, is made up of a series of panels 2l-2829- A plurality of such panelssufficient to cover that portion of the side Wall extending from a door post to the corner, are Ycut to the proper size and the same riveted together along ,vertical adjacent overlappedv edges, as indicated by the series of rivets 39-39. Also, preferably prior to application to the car structure, the riveted assembly of the panels has secured thereto along its upper edge, a Z-bar 3l riveted Vby the horizontal series of rivets 132. Also preferably before application to the car structure, the panel assembly has secured thereto along its bottom edge another heavier Z-bar 32 as by the horizontal series of rivets 33.Y Similarly, there is secured to the vertical edge of the panel assembly to be associated with the door post, a slightly offset plate 34 asby the series of rivets 35. The Z-bar 3| vand plate 34 aregprovided with holes at suitable spaced intervals for the accommodation of bolts, as indicated at 3B and 3l respectively, and the inner depending ange ofi-the Z-bar 32 is punched at suitable intervals to accommodate the rivets Sil-38. It will also be understood that the Wood side plate I2, and door post l5 are, in the meantime, suitably bored for the reception of the bolts 36 and 37; and the side sill Il drilled for reception of the rivets 38. Also, the intermediate posts I E vare bored at suitable'spaced intervals for the reception of shoulder bolt rivets 3S-39 and the latter set in place, Each of said shoulder bolt rivets 39 comprises a main shank 4! extending through the post and threaded at its inner end for the yreception of a nut 4|; an integral annular shoulder or boss 42 engaging against the outer surface of the post, and an initially outwardly extended rivet shank` 43, indicated by dotted lines in FigureV 2. After-the bolt rivets 39 have been set yin place and the panel assembly having been provided with suitable openings in the riveted lap joints to correspond with the location of the bolt rivets, the assembly is then placed in position, the Z-bar 32 riveted to the side sill l l, the upper Z-bar 3| bolted by the bolts 36 to the sidegplate, and the offset plate 34 bolted to the door post by the bolts 31. As Will be apparent, the plate 3l provides a weather sealed joint or connection between the upper edge of the sheathing and side plate; the Z bar 32 a similar connection'between the lower edge of the sheathing and side sill and the plate 34 a similar connection between the sheathing and door post. At the same' time,

it is obvious that the rivet Shanks 43 will be entered through the corresponding openings of the panel assembly after which the rivet shanks 43 are then upset and the heads formed, the bolt rivets being suitably bucked at their inner ends during this process. The vertical end edge of the panel assembly is also connected to the vertical edge flange fil of the metal end lil as bythe vertical series ofrivets 48, access on the innerside for the bucking up tool being'p'ossible because of the temporary removal of the corner post i8. After the metal sheathing has been secured inplace as described, the corner post i8 may thenbe replaced and also the inner Ylining 2%, as. vfell asl the vertical tie bolts 49 which will also have been previously removed, the lower ends of said tie bolts now being secured to the horizontal .Web of the Z-bar, as best shown in Figure 2.

' With theconstruction shown and described, it isqevidentthat substantiallythe Ventire weight of the metal sheathing assemblyis transferred to` amlsustainedv by the vvlower, Z-bar, ,which in turn `is rigidly and permanently connected to the side sill Hiof the underframe thus relieving all theV Wood frame elements ofthe superstructure from ahyappreciable load, the various bolt at taching means thereto functioning primarily to retain thelsheathing assembly inV place. /lnthis manner, theseveral, seriesof bolts 39, .'iand 3l are substantially entirely relieved of any Weight-V sustainingv function and hence will not Wear loose in their/respective Wood element supports.

It will valso be noted a strong riveted connection,

is provided between the panel structureand the metal end Wall which,.in conjunction With the other connections of the. metal sheathing to the superstructureframeelements and side sill will constitute a very much more rigid lsuperstructure and one less subject to Weaving than thev original Woodsheath construction. Attention is further called to the shoulder .bolt rivets 39 Which-not only provide an exceedingly cheap and eicient mannerA of attachingto theposts and eliminate any necessity for counter-boring the posts forY reception of the heads of. the rivetsV 39,' but additionally insure that Vthe metal sheathing shall be located in the proper plane to maintain the original over-al1 Width of the car. dent from comparison of Figures 2 and 6 where it will be seen that, by use of the spacing'shoulders 42 on the bolt rivets 39, the metal sheathing 'is held in aplaneto compensate for. the diference in thickness of the metal sheathing andthe original Wood sheathing 23. A corner gusset -50 is also preferably riveted to the end Wall l0 and upper end corner of the metal side sheathing, as indicated in Figure l, to further strengthen the assembly against Weaving. Y

After, the metal sheathing has been applied as above described, the Vinner wood lining Z may be replaced 'as well as the grain shedding strips 5l' where the latter are to be employed'.

In the foregoing, only one half', that is, from door post to corner' post of the side wall ofthe car has been referred to specifically but, as will be understood, the structure will be duplicated for the remaining side wall portions of the car. Y

VFrom the'preceding description, it will be seen that all. of. the metal parts may be manufactured at relatively small expense and Vfabricated either at the mills or at the car` repair shops prior to application tothe car. Furthermore the railroads are enabled to salvage Athe greater and still remaining usableparts of those old Woodshe'athed This will be evi--A coicars now in service and which are rapidly failing and, at the same time, obtain a car with a stronger and more serviceable superstructure than originally.

Although the improvements herein shown and described are now considered the preferred manner of. carrying out the invention, the same is by way of illustration only and not by way of limitation, and all changesand modifications coming Within the scope of the appended claims are contemplated.
