Gilpin, Chicago, Ill., assignor to Stand ard Railway Equipment Manufacturing Com pany, Chicago, Ill., a corporation of Delaware ` Application June 16, 1943, Serial No. 491,255 s claims. (c1. 10s-«157) 1 My invention relates to car roofs, and more particularly to a metal walk construction for a car roof of the type wherein th‘e roof sheetsare adapted and arranged to form a roof having al ternating flat-topped panels and fiat-bottom channels connected by rigid upstanding seams located in the channels. Theprincipal object of the present invention is to devise a strong and dur 2 ' the seam-caps, as will be apparent from Fig. 1. The panels are `the deepest at the longitudinal center of the car and decrease in depth progres sively from said center toward the eaves of th car where they merge into the flanges 3. ' Rigidly secured to eitherV side of each seam cap at the longitudinal center of» the car is a walk saddle 8, (Fig. 6), which' is of angle shape, the able, simple and economical lightweight metal car vertical flange of whichis secured to the side of walk construction that can be quickly and easily 10 a seam cap so that the top of the horizontal flange applied to roofs of the above type and that will is in a plane with the upper surface of the panels add little or nothing to the height of the car, thus 'l of the roof sheets. ' The saddles are provided permitting the car roof to be positioned as high with~ transverse cut-out slots `9, which, in the as practicable above the rails within the clear formV shown in Fig. 6,» extend around the corner ancelines established by the railroads and so as 15 of the saddle. ' f to provide a maximum loading capacity for the' car. - Longitudinally aligned metal walk members l0 are provided to ‘extend-betweenthe seam caps, Other objects and advantages of the invention each of which memberscomprises a flat metal> will appear in th'e following description thereof. sh‘eet of a, thicknesssubstantially `equal" tothe Referring now to the accompanying drawings, 20 difference between the depth of the panels ‘l and> formingpart of this application, and wherein like reference characters _indicate like parts: .4 Fig'. 1 is a broken perspective view of part of , a car roof illustrating the application of my im proved walk thereto. . . Fig. 2 is a, longitudinal section through a por tion of a car roof adjacent the walk showing one formY of saddle at one seam cap and another form of saddle at theother seam cap. ` ` Fig. .3 is a, side elevation of oneof the walk 30 the top of the seamcap 6 so that Lwhen placed `upon the panel l, transversely thereof-„With theV ends of said members supported upon the saddles Vli, the upper surface ofthe walk members and top. of the >seam-caps, all along the car, will be in the same plane,.with no projections on said surface, and thus such construction of walk com ' plies with the Safety.

Figure 6 is a perspective view of the preferred The sides of th'e walk members are also turned form of saddle. downwardly forming similar iìanges at the sides Y FigureV ’7 is a perspective view of a modified of the ends of the members. The flanges formed form of saddle. at the slits are spaced so as to extend within the In the drawings the invention is illustrated as 40 cut-out slots 9 of the saddles, and the side flanges applied to an all metal car roof which comprises are spaced so as to overlap the ends of the sad a plurality of roof sheets 2 extending between the dles, in which' position the walk members are se opposite side walls of the car, the outer ends of f cured inY any desired manner to said saddles. said sheets being downwardlyflanged, as at 3, The flanges in the ends of the walk’members and rigidly secured to the side _plates 4 of th'e_car.j 45 are extendedv inwardly from the ends of the mem 'I'he side edges of said roof sheets 2 are provided bers a distance equal to the width of that area with upstanding flanges 5, which ñanges 5 of. ad of the roof sheets between the seam‘ñange and jacent sheets abut >one another forming a seam, the panel 1 to adequately reinforce said members which seams are straddled by an overlapping in wh'ere they span rsaid area.

Be tween the seams each roof sheet is provided with a longitudinal central upwardly extending fiatf topped panel 'l which is of slightly less depth than 65 upper surface of the panels are iirst given a heavy coat of .paint or car cement and then the mem bers are applied, thus sealing said members to said panels and preventing moisture collecting by capillary action thereunder. .

In the case of metal members being used, the upper surface thereof would be rough-v ened 0r knurled somewhat, and in th'e case of` a wooden board being used, the upper surface would'be‘ left rough, so that in either event the from a side of said panel to Vthe adjacent seam construction, each of said end parts being formed with a, longitudinal slit'extendin'g substantially . from the end of the member to adjacent the roof car Walk would have anti-slip qualities. sheet panel, and flanges formed in said members Either in lieu of or in addition to the provi sion of a coat of paint or car cement on the pan-ï at the sides of said slit. els under the walk members, for the purposel of preventing moisture collecting thereunder', Vthe sides of said members may be welded to said pan 3.y A structure as defined >in claim l wherein»k said means comprises saddles each provided with a'îvertical arm connected to aseam construction and a horizontal arm'supporting an end .of said member, and wherein the horizontal arm is slot-VV . els and thus more positively secure against water entering between the panels and walk members., ted for the reception of said flanges, said walk In those cases wherein it may not be necessary Y for the ends of the walk membersrto extend up ' saddle supporting saidÍ walk member between. the Vpreferred form oi saddle is used, the modified form’of- saddle, illustrated in Fig. V’7, may be em ployed. _The' only difference between this modi ficationland thai-„illustrated in Fig. 6 is that the member. 4.
