The device relates to railway freight cars and comprises means forming a part of the roof structure which provides places for attaching load lifting devices, such load lifting devices being used to move heavy articles into and out of the car or move sucharticles within the car or to place one part of the load over another part, such as double decking automobiles. i

The connecting member or beam extends longitudinally of the car and is preferably located adjacent the center of the carer may be positioned near the side plate or one near each side plate, or, if desired, may be located in both or in all such positions and still come within the scope of this invention. It may be desirable to raise the load simultaneously a from more than one point. 'Thebeams may extend the full length of the car and reenforce each and every carline or they may simply include a plurality of carlinesand be located as desired. The beams are preferably spaced apart from the roof to provlde a space so a chain or rope may be thrown over the beam to support a block and tackle or differential chain or other device.

In the drawings: Fig. 1 shows a load lifting beam and associated parts of the car.

'Fig. 2'is a vertical longitudinal cross-section on the line 22 in Fig. 1, showing the connection of the load lifting beamof the carline.

Figs. 3, l and 5 show modified forms of construction.

The drawings show my improved load lifting device applied to the standard A. R. A. car roof for freight cars, which consists of a channel shape carline 2 comprising substan; tially vertical walls 8, having lateral flanges 4 at the upper margin ofeach vertical wall and a plurality ofroof sheetssecured to said flanges with certain of said sheets overlapping the channel of the carline. This construction forms a boX girder so that it is impracticable to attach anything tothewalls S of thecarlines on account of the difiiculty of getting at the inside head rivet (or the nut of a bolt) to remove or replace 1t. This is a serious condltlon in building new 7 same distance as between the centers of ad-- 1214061113 'carlines These pipes pass through' cars and also in repairing cars. Furtlfer-' more, makesit quite difficult-t0 apply alload lifting beam to cars already-built" i Fig. 1 illustrates the relation of-a loadliftingbeam 7 to the other parts of thecar',such 3 as the side plates 10," carline2, roof: shiaet 5' and running boards 11'. I In the form illustrated the load lifting beam 7 comprises a*plurality.iof pipes, the

length .of each pipe being substantially the apertures in" the walls 30f the 'carlines and are retained therein by a cotter (20) boltor slmilanmeans'which passes through thepipe adjacent each wall oftheicarlinezwrFig.;.-2

Fig. 4 shows a modified form wherein the end of the pipe is deflected 24 out of alignment to accommodate a'sloping wall of a' carline. v

Fig. 5 shows another modified form wherein the pipes forming the beam extend through and are supportedby both walls of the carline and are connected somewhere between adjacent carlines by the coupling 30 or other similar means.v p:
