The floor rack of the- present invention is in tended'primarily for use of the floors of refrig erator cars or the like and to be substituted in place of the wooden ñoor racks now commonly li in use. ' ` (Cl. 20-78) or fabricated to afford upstanding ribs i3 in the nature of slats which are separated from one another by valleys~ I4. The ribs comprise flat top walls i5, all of which lie in the same plane to present a flush surface for the support of the The floor rack of the present invention together ` kegs, boxes, crates, packages or the like, which with Ithe supports therefor are of metallic con- ' constitute the lading of the car. The ribs also ,_ struction, which possesses positive advantages in comparison with Wooden floor racks, in that the danger of distortion due to swelling or shrinking is eliminated; so that a more even and uniform surface is present-cd for the storage and move ment of the commodities housed within the car or comprise upstanding side walls I6 which are con nected'by base walls i1 constituting the floors of the valleys between the ribs. The terminal rib 10 of a panel has the lower edge of its outer side wall inturned to afford a flange i8, leaving an open space or gap between the panel and the next _other structure.

'I‘he gaps between the panels are of equal width with the valleys, so that the spacing of the Slat-like ribs is uniform from end constitutes a serious objection. ' cto end of the car floor. ' ovrr. makes provision for increased circulation of air and eliminates ythe possibility of impairment A further advantage lies in the fact that the ` ' metallic slats are of uniform thickness, so that, in the case of repair or replacement, exact di-y mensions will be maintained, which accurate fit vting is often -omitted in the repairing of wooden slatted ñoors where new slats of non-uniform 'thickness‘are employed asreplacements, .result no'. Further yobjects and details of the present in-- provided to enable this section to be folded in vention will appear from a description thereof in be swung up into the position shown in dotted 30 lines in Fig. 2 against the side wall of the car, the conjunction with the accompanying drawings, sections being mounted upon hinges 22; wherein,-- ' ' ' Fig., 1 is‘a plan'view showing the slatted sur 35 / face of a refrigerator car floor, the view showing one halfk of the length of the car; _ Fig. 2 is a sectional elevation of the same, show In order to increase the circulation of air, the floors of the valleys between the ribs are provided with elongated apertures 23, which gives to the 35 slatted construction as a whole the character of ing the manner of folding the slatted sections into a foraminous surface to facilitate the flow of air without sacrifice’ of the stiffness and rigidity re vertical relation to the car walls; quired in a structure of this character. ‘ Fig. 3 is an enlarged detail showing the pre ferred construction of the slatted panels; Fig. 4 is a sectional elevation taken on line Il--l of Fig. 3; Fig. 5 is a sectional detail taken on lineîä ofv 45 to the transverse center line of the car and ad jacent to the car door, and the hinges 2| are ‘ wardly upon the adjacent section A. which may ing in inequalities in» the ñoor surface. 40 The innermost section A, as shown, has hinged thereto a center section B connected by hinges 2i with the contiguous section A. The hinged section B occupies a space immediately adjacent 25 Fig. 3; . , . Fig.y 6 is a plan view of a modified form of con struction; l - \ ~ _ Fig. 7 is an edge view of the same; and ' ` Fig. B is a sectional detail taken on line IL-l4 Referring particularly to the construction first q illustrated, the slatted flooring of the car consists . The slatted sections', each comprising three vpanels in the form shown, are supported upon stringers 24 which, as shown, extend lengthwise of the car and which are of channel construction standing on edge to afford a vertical wall 25, and . top and bottom walls 26 and 21, which latter are reinforced at recurrent intervals by vertical plates 2l provided with flanges 29, which rplates consti tute spacers and which are preferably spot welded in position to further strengthen the stringers to thenecessary extent. As shown, the stringers are imperforate, since they extend lengthwise of -the car and do not obstruct the ñow of air be of aplurality'oi sections A each of which consists _of slatted panels l0, il , I2. Each panel is in neath the lading, although, if desired, the walls oi.' the stringers 24 may be provided with aper tegrally formed of plate metal which is pressed tures. v 50 2,107,853 The hinges 2! comprise hinge members Il in the form of brackets secured to the floor sections in conjunction with ilxed brackets Il of anzu _lar` formation fitted into ythe angle between the floor and the. wall of the car, which members are pivoted together upon a pintle 32. It is preferred to spot weld the panels directly to the stringers, -Furthermore, the employment of metal elim inates the absorption of moisture with resultant fodors, which >in _the case of wooden slatted «cars vare frequently present and difficult to eliminate, and are most objectionable in the transportation although other means of securement may be em offfoodstuffs or the like which may be contam inated by such odors. _ 'I'hel construction employing vintegral panels possesses certain special advantages in reduction ployed. Although in the oonstruouon described, theV of manufacturing costs and in rigidity of con 10 stringers run 'lengthwise thereof, a vreversal of this arrangement is contemplated if desired, and struction, since the spacing of the slats is in' herent in the'panel itself and is not dependent' upon the connection of the slats to the string ' it is not the intention to limit the invention to ers as in the case of the individually formed slats. slatted surfaces run crosswise of the car, and the the arrangement shown by way of exempliilca tion in the drawings. ` ì The construction shown in Fig. 6 illustrates a siat arrangement in which ythemetallic slats 33 run lengthwiœ of the car and are supported upon 20 stringers 36 running cros’swise ci’ the car. In >this construction, instead of providing a multi plicity of slats in the form of ribs struck' up wardly from an integral plate of metal, the slats _are individually formed, e'ach 'slat comprising a top wall 35 and side walls or flanges 36,',which I are inturned at their lower edges to afford flanges' ..30 Furthermore, by maintaining accurate spacing` of the slats. the gaps between the same may .be reduced to the extent necessary to prevent -the 4lodgment of materials between the slats, and by the maintenance of uniformity in the plane ' of the slatted floor surface, the movement and storing of commodities is facilitated. Although the invention 'l has been' described with particularity as to detail, it is not the in tention to limit the invention to the forms of construction shown, since modifications thereof are 'within the scope of the invention. 31 which rest upon the underlying stringers. In I claim: this case the individual slats are provided in 1. A slatted iloor for cars or the like, compris their top walls with flanged apertures 38 .like those first described. In order to holdthe stringers 34 in elevated relation to the car floor, each of the stringers is provided with feet 39 which, as shown, are of I trough-shaped formation comprising a base 60 35 and diverging side walls> 4i 'which are spot weld ed or otherwise connected aty their upper edges to the stringer.

'As shown uniform horizontal plane and constituting slats with intervening valleys, the slats being'provided with downwardly flanged apertures to promote 45 in Fig. 6, the slatted section C comprises a plu- f the circulating of air therethrough, and stringers . , located beneath the panels and extending trans rality of individual slats mounted upon tr'ans versely extending stringers,y and the center sec tion D is. secured to the end of the sec _ tion C by hinges I4' to’enable the section D to 50 be swung inwardly against the section C~»when 'the latter is turned upwardlyupon its hinges 45. Although in the form of construction shown Vin Fig. 6 the slats extend lengthwise of the car. -and the stringers extend transversely, it yis ob' vious that a section of this construction might be otherwise arranged to bring the slats into I transverse relation to the car body. In> either form of construction, full provision is made for the circulation of the air which flows 60 longitudinally of the car along the car ñoor and up through the interstices afforded between the slats, whether the latter be formed integrally or individually. The slats andl stringers, being of channel formation, afford great rigidity, and at 65 thev same time the method oi connecting the parts by spot weldingl or the like prevents the possibility of displacement orv distortion diue to warping or rotting of the material. ~This also versely with‘frespect to the slats formed therein for elevatingr the panels above the floor level of the ca'r or the like.
