2 center sills) are supplemented on their outer sides by longitudinal wooden beams 22 which are housed within the flanges of protecting longitudinal supplemental channels 2|. These parts aresecured together by through bolts 25, 2S, extending through the webs of the two channels and the intermediate wooden beam. As indicated'in Fig. 7, I prefer 'to provide an angle bar 21 resting on the top iianges 'of both channel beams 20 and 2i andextending down the cuter face oi the outer channel beam and welded at its edges to the channel beams. The construction described is very effective in resisting lateral stresses against `the side of the car, Without unduly increasing the weight ofthe car or its Width.

The side reinforcing may be readily applied to eldsting cars, the reinforcing beams 22 and the protecting channels 2i taking the place of the region ordinarily occupied by stake pockets. Accordingly, by removing the stake pockets and supplying the additional reinforce, I not only strengthen the side sills against lateral distor-y tion, but I'increase the eii'ective floor width of the car without increasing the over--alll dimension. I may utilize the original stake pocket holes in the car sills 20 for placing some of the bolts by which I secure the reinforcing side beam.

As car widths vary somewhat, the wooden filler beams 22 may be of variable widths according to the size of the car, with the result of bringing the entire width up to the standard desirable for carrying demountable bodies.

The normal side sill members 20 and the center sills ordinarily carry the flooring. This may be suitable planking extending from side to side of the car, as indicated at 30 in Fig. 6. Now, when I mount my cross-channels on the car, I omit or remove this planking at stated intervals and insert in place thereof the channel guides which are supported at their ends on-both longitudinal protecting channels 20 and 2| and intermediately on the door planking.

The skid-receiving channel is composed of an approximately V-shaped upper member 4U and a lower member 45. 'Fae upper. member has a iiat central zone 4i, then two outwardly inclined zones 42, and iinally horizontal top edge flanges 43. The member 45 is a flat plate contacting with the flat portion 4| of the channel and welded or otherwise secured thereto. In the spaces between the top flanges 43 and the plate 45 forming the bottom member I mount anglel bars 48. f

The cross-channel rests on the angle bar 21 of the side sills, as shown in Fig. 7, but may shift somewhat longitudinally of the car thereon. 'I'he channel isheld against lateral shifting by strap plates 35 secured to the floor Il) and bent downwardly at their ends at an angle at 36, Fig. '7, across the `correspondingly chamfered ends of the channel guide, the strap plates having finally vertical portions 31. engaging the vertical vwebs of the angle irons 21, and bolted to the entire side sill.

ses

As shown in Fig. y10, the floor `piani-ring 30 is protected by a transverse angle barj32 andsuitable bolts ll pass through the strap plates 35 and the planking 30 to hold these parts together. Between the vertical iianges of the angle bars 48 and the vertical flanges oi' the iloor planking pro. tectors 32, I place suitable yielding cushions, as,"

for instance, the rubber blocks. 5|! of Fig. 10.

It will be seen from the description given, that thechannel guides are nrmly retained on the car against movement crosswise or the car or up or down. but may move slightly in a horizontal plane lengthwise of the car as the rubber blocks 50 on one side or the other are compressed. This shock-absorbing feature reduces the jar on the container and contents in case of sudden starting or stopping of the car.

Fig. shows the yielding resistors for the guide channels as solid blocks of rubber 5i). It is to be understood, however, that other forms of yielding cushions may be employed, as desired. For instance, in Fig. 11, I have illustrated diagonal zig-zag 'rubber 5i; in Fig. l2 cellular rubber 5f?, and other forms of'blocks may be used.

As thetruck bridges D in iny system, which are 'to be temporarily attached to the car sides, cooperate directly with the car channels Ml as the body is being shifted from one vehicle to ythe other across the bridges, I find it .very efficient to attach the bridges directly to 'the ends of the channel guides. This is illustrated particularly in Figs. 6 to 9, and will now be described.

The vertical end portions 3l of the strap plates 35 have welded to them Vertical tubular members 38 adapted to receive hinge pins connected with ears on the attaching brackets 80. Such ears are shown at 6i extending above and below the stationary tubular member 38 and a pintle 53 extends through such aligned parts, so that the brackets are eiiectively hinged to the supplemental car side and thechannel retaining straps. The brackets 60, when not in use, lieiiat against the side of the car, as shown in Fig. 8,

and are there held by a suitable retaining device' carried by the car side. As shown, I have Welded a vertical tubular member 39 to the plate portion E'Imidway between the hinge members 38.'

the pin 10 carries the head 1| above the flanges 6.5, and releases the wings so that they may be swung out at right angles to the car, as shown in Fig. 9.

The attaching wings are shown as having horizontal slots 61 through them, these slots belng adapted to be occupied by cross-members on the ends of the bridges D. As indicated in' Figs. 1 and 3, these bridges carry transversely of their ends suitable tubes d adapted to occupy the slots 81. These tubes may contain rods with downturneduends di, Fig. 3, which may overhang'the brackets and-prevent separation of the parts. When the brackets are to be attached to the bridge-tubes d, the latter are positioned in substantial registration with the slots 81 and the brackets are manually swung inwardly so that the tube extensions pass into the slots while the rodv endsvdl are held projecting horizontally. Then, when the rod end is released, the same drops by gravity into the position shown in Fig. 3, holding the parts together.

The system of locking the bridge to the car by the slotted brackets ard cross-tubes on the -bridge Aand the bent bars occpying the tubes lis claimed in my prior application 32,131, referred to. The feature here claimed is the association of bridgeattaching brackets with the supplemental side 75- dit 'alzarsi sills of the car and the channel guide holding straps.

The attaching straps ss ci this invention preferably have the bracket ear members 38 secured to them inthe shop, and likewise the pin holder 39 secured in the shop to the flange of the angle iron 21. The members dt, it and 43 of the channel guide are also preferably secured together as aunit in the shop. It ls therefore only necessary in preparing the flat car having the usual side channel 2i) and flooring tt to remove the flooring at intervals; apply the protecting bars 32; bolt on the side beams 22 and protecting channels ti tally aligned and adapted to occupy the slots tl t ci the brackets when the latter are against the car side. The final operation of attaching the device to the oar may be the insertion of the bolts dit through the marginal portion of the .straps 35 in the car floor. l

It will be seen that my construction provides for simple and emcient shock-absorbing channel guides for the car; provides for the ready mounting of such guides on ordinary fiat cars; furnishes the desirablecharacteristic of enabling 'effective bracing of the car sides against lateral stresses,

ati, land the desirable characteristic of readily widendit itil

ing existing cars in the region ordinarily occupied by stake pockets, and finally the construction enables the direct anchorage of the truck bridge to parts in the immediate vicinity of the receiving channels to prevent any bending moments ,in such side structure. 1
