AnhurE 512121! Patented June 14, 1932 UNETED gTATES PATENT QFFICE ARTHUR E. SMALL, 9F CHICAGO, ILLINOIS, ASSIGNOR TO P. H. MURPHY COMPANY, OF NEW KENSINGTON, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA LOAD LIFTING ARRANGEMENT FOR RAILWAY CARS Application filed May 28,

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

The connec ing member or beam extends longitudinally of the car and is preferably located adjacent the center of the car or 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 from more than one point. The beams may extend the full length of the car and reenforce each and every carline or they may simply include a plurality of carlines and be located as desired. The beams are preferably spaced apart from the roof to provide 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 drawing:

Fig. 1 shows a load lifting beam and assoc'ated parts of the car.

Figs. 2 and 3 show the connection of a load lifting beam to a carline.

F 4 and 5 show a modified form wherein the bracket is eliminated.

Fig. 6 shows the detail of the bracket.

The drawing shows 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 substantially vertical walls 3 having lateral flanges 4 at the upper margin of each vertical wall and a plurality of roof sheets 5 secured to said flanges with certain of said sheets overlapping the channel of the carline. This construction forms a box so that it is impracticable to attach anything to the walls 3 of the carlines on account of the difliculty of getting at the inside head of a rivet (or the nut of a bolt) to remove or replace it. This is a serious condition in building new cars and also in repairing cars. Furthermore, makes 1930. Serial No. 456,577.

it quite difficult to apply a load lifting beam to cars already built.

Fig. 1 illustrates the relation of a load lifting beam 7 to the other parts of the car, such as the side plates 10, carline 2 roof sheet 5 and running boards 11.

In the form illustrated in Figs. 2 and 3 the bracket is secured to the carline by means of a bolt 21 which penetrates through both walls thereof and is held in place by the nut 22 or other means, which arrangement can easily be applied to new or existing equipment. This bracket is preferably provided with spaced apart wings 25 on each side thereof to which the load lifting beam 7 is secured by means of the bolt 26 forming a pivoted connection between the beam and the carline.

The beam is preferably spaced below the roof sheets so as to provide a space (28) over which a rope or chain may be thrown to support a load lifting device, but the bottom of the beam is not lower than the bottom of the carline.

In the form illustrated in Figs. 4 and 5 each load lifting beam 30 is provided with an upwardly projecting flange 31 which preferably engages the adjacent vertical wall 3 of the carline andthe flanges (31) of adjacent beams are secured together and to the carline by means of a bolt 33 or other similar device passing through the carlines and said flanges. The bottom parts (34:) of these beams are not lower thanthe bottom portion (35) of the carline so as not to reduce the inside vertical clear height of the car.

Fig. 6 shows the bracket in detail, which comprises spaced apart portions for engagement with the vertical walls 3 of the carline and a connecting web member 41 and a pair of wings 25 on each side of the bracket which are provided with apertures 42 to accommodate the pivotal connection of the beam.

While I have shown channel shaped beams, it is understood that any other shape beam may be used and still come within the scope of the invention.

' The accompanying drawing illustrates the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof, within the scope of the claims, will occur to persons skilled in the art.

I claim:

1. In a railway car, the combination of a U-shaped carline having spaced apart substantially vertical walls, roofing secured to said carline and closing the channels therein, a bracket having spaced apart portions on opposite sides of the carline, means passing through both walls of said carline and through both portions of said bracket to secure the bracket to the carline, and load lifting beams secured to said bracket of said carline.

2. In a railway car, the combination of a U-shaped carline having spaced apart substantially vertical walls with lateral flanges at the upper margins thereof, roofing secured to said flanges, a bracket having spaced apart portions on opposite sides of the carline, each of said portions having spaced apart wings, means passing through both walls of said carline and both portions of said bracket to secure the bracket to the carline, and load lifting beams secured to said wings.

3. In a railway car, the combination of a Usl1aped carline having spaced apart substantially vertical walls with lateral flanges at the upper margins thereof, roofing secured to said flanges, a bracket having spaced apart portions on opposite sides of the carline, means passing through both walls of said carlines and through both spaced apart portions of said bracket to secure the bracket to the carline, and load lifting beams secured to said bracket of said carline, the bottom of the beam being not lower than the bottom of the bracket.

4. In a railway car, the combination of spaced apart U-shaped carlines, each having spaced apart substantially vertical walls with lateral flanges at the upper margins thereof, roofing secured to said flanges, a load lifting beam spanning the distance between said carlin es, and means passing through both of said spaced walls to secure the beam to the carline.

5. In a railway car, the combination of spaced apart U-shaped carlines, each having spaced apart substantially vertical walls with lateral flanges at the upper margins thereof, roofing secured to said flanges, and a load lifting beam spanning the distance between said carlines with its opposite ends pivotally secured to said carlines.

6. A railway car construction comprising side plates connected by hollow carlines, a load-lifting beam extending longitudinally of the car between carlines, brackets for attaching the ends of said beam to said carlines, and means for securing said brackets to said carlines, said means comprising members passing through alined openings provided therefor in said brackets and in both side walls of said hollow carlines.

7. A railway car construction comprising side plates connected by hollow carlines, a load-lifting beam comprising sect-ions extending longitudinally of the car between carlines, brackets for attaching the adjacent ends of the lifting beam sections to said carlines, said brackets having side portions engaging both sides of said carlines, and means for securing said brackets to said carlines, said means comprising members passing through alined openings provided therefor in both side portions of said brackets and in both sides of said carlines.

8. A railway car construction comprising side plates connected by carlines of substantially channel-shaped cross-section, a loadlifting beam extending longitudinally of the car between carlines, brackets for attaching the ends of said beam to said carlines, and means for securing said brackets to said carlines, said means comprising members passing through said brackets and through both side walls of said carlines.
