As vmy `invention pertains to thek means for 1 hingedly connecting the respective floor-rackl sectionst'oeaoh other, a detailed ldescription `ofthe car proper need not be entered into. y

"Thefloor-racks are generally made `in se'o- A tions'of suitable length to extend intermediate ofthe 4car-door openings andthe endsl Aof the freightholding portion ofY the car,

with separate sections at the door openings, and of width substantially equal to half the width of the car interior, in order that similar sections may be arranged on each side of y, the longitudinal lcenter line of the car.

'Thai bolts 718 preferably are ilffasidiowzm in miglia-et,- soiaslnotlto interfere with proper movement mf :the imneetig member 22. One end of member 2Q is piuotllyaequmd by meansfia suitable rivet-amt 23 W, to plate 1l? `attached to -stringer f1.4, eee Figure 4. Theladg'went .end of Stringer 16 `.ofthelom1:a.ck section 13 iis :likewise gproate 17 y:secured .tothe longitudinal face of t e strngerf'as'previously describedA and .this rplate has the .opposite end of the ACorine'ctingig member 22 pivote-ily secured thereto'at 23, see Figures 2, 3 ,and L5. As shown, in FigureZ the plates 17 are secured 'to `the opposite sides or longitudinal ,130 faces offthestringers Maud 16 in order thatA the non-flexing connecting element 23 may extend parallel.withthe` stringers.`

The connecting member 22 preferably consists of a somewhat`Ushape`metaly strap with the pivot-forming` rivets 23 disposed thiough the ends ofthe member which are secured to the plates jat a pointv just beneath the runners or planks 15. 'These connecting members 22 are of such length that the spacing between the connected floor-rack sections will be equivalent to or not greater'k than the predetermined designated spacing between the superposed planks l5 yof a section, as will be seen in Figures 1,2 and 3. At

the same time the ends of the connectingf `member 22 are a distance apart approximating the vertical width of-eitherlsleepers or stringers 14 or 1.6 in order to permit the stringers of two pivotally connected sectionsy to be vmoved into lparallel nestingrelation as shown in Figurey 5`- and atthe lower yside of Figure l to the right. of the doory opening 11,-thus permitting the connectedrack-sections to be disposed parallel withfeach other j inV lthe baclr-to-bac-k compact relation disclosed. When thev sections Vare/folded into Y 1 back-to-back relation, theconnectingmember 22 will be disposedina horizontalfplane; whereas when a section is foldedgoveronto an adjacent section in face-to-face relation the connecting member 22 will be vertically disposed as shown in dotted linesY in Figure 3, at which time the connecting member will s-traddle the endy planks 15 of the two connected sections. A i Y lt is apparent from the construction shown l that no lateral or sidewiseV play of the connected sections is otal connection between the lsections is such that la free swinging movement into either of the positions mentioned may be quickly madel without special adjustment or movement oth! er than the lifting opta-section upwardly and f onto the lowered floor-rack section forfaceto-face relation, or swinging the free ,end through the are ota horizontally disposed circle after the largepermanently-secured section has been swung upwardly against the side of the car wall. A With my improvedvconnecting means a binding of the 'connecting means is j possible and'that the piv- Y bination with a pair of aligned sections, a single piece member, the opposite ends whereof are pivotally connected to the opposing endsfof said floor-rack sections, while the intermediate portionoi' said member is disposed toward one side of the pivotal axes ofsaid endsf l 2.
