'11 Claims. Cl, 105-369) This invention relates, generally, to lading tie anchors for railway cars and it has particular relation to such anchors for gondola cars.

-Among the objects of this invention are: To provide for receiving either lading tie rods or flexible lading ties in the form of straps at spaced locations along the top side chords of railway gondola cars; to space the channels forming the top side chords and facilitate assembly there of; to center and laterally support the lading tie rods while providing for the application of lading tie straps in the absence of the rods; to employ a generally rectangular tubular member for the foregoing purposes; to form the generally rectangular tubular member of two identical drop forgings; and to form the generally rectangular tubular member of a one piece steel casting.

Other objects of this invention will, in part, be obvious and in part appear hereinafter.

This invention is disclosed in the embodiments thereof shown in the accompanying drawings and it comprises the features of construction, combination or elements and arrangement of parts that will be exemplified in the con structions hereinafter set forth and the scope of the application of which will be indicated in the appended claims. i

For a more complete understanding of the nature and scope of this invention reference can be had to the following detailed description, taken together with the accompanying drawings in which:

Figure 1 is a topplan view of a portion of a top side chord of a railway gondola car embodying the present invention;

Figure 2 is a vertical sectional view taken generally along the line 22 of Figure -1;

Figure 3 is a vertical sectional view taken generally along the line 3-3 of Figure 1;

Figure 4 is a view, in front elevation, of one of the drop forgings that is employed to form the generally rectangular tube shown in Figures 1, 2' and 3 of the drawings;

Figure 5 is a view partly in horizontal section and partly in top plan and taken generally along the line 5-5 of Figure.4;

Figure 6 is a horizontal sectional view taken generally along the line 6-6 of Figure 4;

Figure 7 is a vertical sectional view taken generally Figure 11 is a vertical sectional view taken generally" along the line 11-11 of Figure 10; and

Figure 12 is a horizontal sectional view taken general- 1y along the line 12-12 of Figure 10.

Referring now particularlyto Figures 1, 2 and 3 of the drawings, it will be observed that the reference character 10 designates, generally, a top side chord for a railway gondola car. 'It is formed as a box like structure by a lower channel member 11 and an upper channel member 12 which preferably are formed of rolled structural steel shapes. The lower channel member 11 has upstanding side flanges 13 which interfit between depending side flanges 14 of the upper channel member '12. They are secured inseparably together by welding as indicated at 15. 'While the flanges 13 are indicated as being telescoped' between the depending flanges 14, it will be understood that the channel members 11 and 12 can be of identical size'in which case the upper edges ofthe side flanges 13 would register with the lower edges of the depending flanges 14.

The lower channel member 11 is welded at 16 and '17 to a car side plate 18. Since the other portions of the car structure form no part of the present invention and since they are well understood in the art, further description of the car structure will not be set forth herein.

The present invention has to do particularly with the construction of the top side chord 10 so that it is capable of receiving various types of lading ties. As presently constructed gondola cars are manufactured to widths which just comply with maximum allowable clearance lines. Assuming that the top side chord 10 extends along the left side of a gondola car, then the left side of the top chord 10 extends to the limit of the width which is permitted by regulations which provide for a minimum clearance between cars on adjacent tracks. There is then little room for the application of lading tie receiving means beyond the left side of the top chord 10.

Because the gondola cars are used for handling various types of lading, it is desirable to provide for different types of lading ties. In particular it is desirable to provide for the application of flexible lading tie straps as indicated e by broken lines at 21 in Figure 2.- Also it is desirable tie rod 22 having a circular cross section by the same lading tie receiving means.

For this purpose the central portions 25 and 26 of the lower and upper channel members 11 and 12 are provided with registering generally rectangular openings 27 and 28. These openings can be formed by, a suitable punching operation. Interconnecting the registering rectangular openings 27 and 28 is a generally rectangular tube that is indicated, generally, at '29. The tube 29, as

will appear presently, is arranged to receive either the flexiblelading tie strap 21 or the lading tie rod 22 of solid cross section.

pair of drop, forgings 30, one of which is shown in Figure 4, or, as will appear hereinafter, it can be formed of a one piece steel casting. When it is formed of a pair of drop forgings 30, they are of identical construction to reduce cost and facilitate assembly.

As illustrated in Figures 1 and 2 of the drawings, the lower and upper ends of the generally rectangular tube 29 are welded as indicated at 31 and 32 to the central portions 25 and 26 of the lower and upper channel members 11 and 12. Preferably the construction is such that the ends of the generally rectangular tube 29 do not project above or below the outer surfaces of the central portions 2's and 26 of the channel members 11 and 12.

When the channel members 11 and 12 are assembled wood blocks. 1 Since no practical way has been devised for removing the wood spacing blocks after the channel been necessary to leave them in the assembly.

In accordance with the present invention the use of the wood spacing bloclgs can be avoided by the provision of shoulders 33 and 34 near the endsot the generally rec tangular tube 29. It will be observed that these shoulders engage the adjacent faces 35 and 360i the centralportions 25 and 26 and thereby serve to space the channel members 11 and 12 at the proper distance apart to permit the welding at 15 to be carried out. p L 1 With a view to accurately positioning the drop forgings 30 in a pair for forming the generally rectangular tube 29 protuberances 37 and recesses'38 are provided in the juxtaposed edges. As shown in Figure 4 the protuberances 37 are located at the bottom'of one of the forgings 30 and the recesses 38 are located at the top. For the mating forging 30, the same construction is used but it is turned end for end so that the protuberances 37-will register with recesses 38. a v

The inner surfaces of the lower and upper ends of'the generally rectangular tube 29 are rounded as indicated at 41 and 42 in order to avoid the presence of sharp edges which might abrade the flexible tie strap 21 as will be understood readily. I

In order to provide for receiving the lading tie'rod 22 and supportingthe same against lateral movement, ribs 43 are formed integrally with the inner walls of the drop forgings 30. The mid sections or central portions 44 of the ribs 43 provide a circular section 45 of substantial length, as shown more clearly in Figures 1,4 and of the drawings. Since the circular lading tie rod 22 extends through this elongated circular section 45, it is guided thereby and held against lateral movement. In order to provide for the ingress and egress of the flexible lading tie strap 21 in the absence of the lading tie rod 22, the upper and lower ends of the ribs 43 are tapered as indicated at 46 from a maximum height at the mid sections 44 to a minimum at the lower and upper ends-of each drop forging 30.

It is desirable to provide a substantially uniform cross section for the drop forging 30. Accordingly, as shown in Figure 9, grooves 47 are provided in the side'opposite the side provided with the ribs 43.

Referring now particularly to Figures 10, 11 and 12 of the drawings, it will be observed'that the generally rectangular tube 29, previously referred to, is here shown as a one piece steel casting 50. Such a construction can be employed where greater strength is desired and where the additional cost of employing the casting process is warranted. The construction otherwise is the same as for the generally rectangular tube 29, previously described, and made up of two forgings 30.

In assembling the top side chord 10, the generally reo tangular tube 29 constructed of two drop forgings 30 or the one piece casting 50 can be used. The required number of these rectangular tubes are assembled with the lower and upper channel members 11 and 12 so that they are spaced apart by the shoulders 33 and 34 at the lower and upper ends, as previously described. .Then the' side flanges l3 and 14 can be welded together as indicated at 15 and the ends of the generally rectangular tubes 29 can be welded as indicated at 31 and 32. A rigid construction then is provided and it is unnecessary to use the wood spacing blocks previouslyrequired. The rectangular configuration of the tube 29 permits the application of a flexible lading tie strap 21. Since its thickness is relatively small, it does not add substantially to the width of the car. Alternatively the circular section 45 in each of the generally rectangular tubes 29 is adapted to re-' oeive a lading tie rod 22 and to hold the same against lateral movement. 7

Since certain further changes can be made in the foregoing construction and different: embodiments of the in- 4 and scope thereof, it is intended that all matter shown in the accompanying drawings anddescribed hereinbefore shall be interpreted as illustrative and not in a limiting sense.
