MalcoZ/vz 5 Jo/zwom United States Patent O 1 3,125,966 CAR CONSTRUCTION Malcolm S. Johnson, Flossmoor, Ill., assigner to Illinois Railway Equipment Company, Chicago, Ill., a corporation of Illinois Filed Feb. 27, 1959, Ser. Nc. 796,129 2 Claims. (Cl. 10S- 369) This invention relates, generally, to the construction of railway freight cars and the like and it has particular relation to the provision of lading tie anchors therein. This application is a continuation-impart of application Serial No. 593,063, led June 22, 1956, now abandoned.

It is conventional to construct railway freight cars having the upper portion of the lining formed by matched boards or by plywood and the lower portion, just above the floor formed by steel wall plate. The steel wall plate is employed for reducing the damage to the mterior of the car by fork lift trucks and like devices used for loading and unloading lading. The wood lining is secured to nailing strips associated with vertical metallic car side posts comprising rolled structural members having a Z-shaped cross section. The wall plate overlies the lower portions of the car side posts and is welded thereto along the upper and lower edges. When lading anchor means are applied to such wall plate, the same is likely to be torn loose from the car side posts because of the limited extent of joinder thereto unless special provision is made, as disclosed herein, for preventing such action.

Accordingly, among the objects of this invention are: To secure such wall plate provided with lading tie anchors to the car side posts in such manner that the same remains in place regardless of the stress likely to be applied thereto; to place the lading tie anchors in the wall plate in registry with the car side posts and to secure the anchors both to the wall plate and to the car side posts in order that stress applied to the anchors will be transmitted directly to the car side posts; to provide lading tie anchors in metallic members welded to the inner flanges of the car side posts to the vertical sides of which members the metallic wall plate is welded along the ends thereof; to provide a plurality of lading ties in each member in a new and improved manner; to provide the part of the anchor to which stress is applied by a lading tie in the form of a pair of posts extending toward each other from opposite sides of the lading tie receiving cavity; to provide a concave surface at the end of one of the posts to facilitate entry of a lading tie in the form of a strap or a wire between the juxtaposed ends of the posts; and to shape the rear surface of the other post in such manner as to cause a lading tie in the form of a strap to engage both posts when tension is applied to the lading tie.

FIGURE 9 is a horizontal sectional View taken generally along the line 9-9 of FIGURE 6; and

FIGURE l0 is a horizontal sectional View taken generally along the line IIL-10 of FIGURE 6.

Referring now particularly to FIGURES l and 2 of the drawings, it will be observed that the

reference characters

52 and 53 designate elongated anchor members, preferably formed of drop forged steel, which are arranged to overlie the surface 16 of the inner flange 15 that forms an integral part of a car side post 13 of conventional Z-shape having an intermediate web 14. For simplicity in manufacture the

anchor members

52 and 53 are formed individually.

It will be observed that an upper portion 54 of the elongated anchor member 52 extends into a recess 55 in the lower front surface of a lower lining board 56. It will be understood that the recess 55 can be formed along the lower edge of a length of plywood, if desired. The lower end portion 57 of the elongated anchor member 53 is inclined inwardly to reduce the likelihood of rupturing lading containers such as bags and boxes.

Each of the

elongated anchor members

52 and 53 is provided with vertically spaced lading tie receiving openings 58. As shown, two pairs of these openings 58 are provided in each of the

anchor members

52 and 53. The construction associated with each pair of openings 58 is the same and is illustrated in more detail in FIGURE 5.

As shown in FIGURE 5 the lading tie receiving openings 58 are associated with side walls 59 that extend to the surface 16 of the inner flange 15 and are welded thereto as indicated at 59'. End walls 60 extending horizontally between the side walls 59 are welded, as indicated at 66 in FIGURE 2, to the surface 16. It will be understood that the welding at 59 and 60 is performed through the openings 58 and serves to hold the

elongated anchor members

52 and 53 securely in position on the respective inner flange 15. The side walls 59 and end walls 60 define a cavity 61 which opens to the interior of the car and across which a bar 62 extends for receiving a lading tie therearound. The bar 62 in each instance constitutes a continuation of the main body portion of the

respective anchor members

52 and 53.

Along the lateral sides of the

elongated anchor members

52 and 53 are outwardly extending flanges 63 which, as shown in FIGURES 3, 4 and 5 are spaced away from the inner surfaces of the

anchor members

52 and 53 in the direction of the surface 16 of the inner ange 15. The flanges 63 are provided for receiving wall plates 64 and the thickness of which is such as to equal the spacing of the flanges 63 from the inwardly facing surfaces of the

anchor members

52 and 53. As a result the inner surfaces of the

wall plates

64 and 65 are coplanar with the inner surfaces of the

anchor members

52 and 53 and together they form the lower portion of the lining of the car. The edges of the

wall plates

64 and 65 which overlie the ianges 63 are welded to the

anchor members

52 and 53 as indicated at 66.

A lading tight construction is provided when the

anchor members

52 and 53 are assembled on the surface 16 of the inner flange 15 in the manner described hav ing the

wall plates

64 and 65 welded thereto in the manner indicated. No open joints or cracks are left through which lading might seep for lodgment in inaccessible places where it might decay and cause subsequent damage.

Referring now particularly to FIGURES 6-10 of the drawings, it will be observed that the construction of the

anchor members

52 and 53, insofar as their application to the surface 16 of the inner flange 15 and attachment of the

wall plates

64 and 65 are concerned, is the same as described hereinbefore for FIGURES 1 to 5 of the drawings. The construction is different in that a single continuous bar 62 is not used for receiving a lading tie and the openings 58 are of slightly diferent shape. In order to facilitate the entry of a lading tie 67 Lin the form of a loop upper and

lower posts

68 and 69 are formed integrally with and extend in aligned relation from the upper and lower sides of the cavity 61. A space 70 between the juxtaposed ends of the upper and

lower posts

68 and 69 permits the application of the lading tie 67 in looped form into the interior of the cavity 61. An important reason for employing two posts, i.e., the upper post 68 and the lower post 69, is to permit the lading tie 67 to react against both posts, as shown in the central portion of FIGURE 7, so that the tension stress applied to the lading tie 67 is distributed over two cantilevers rather than being applied to a single cantilever as has been employed heretofore.

The juxtaposed ends of the upper and

lower posts

63 and 69 are specially formed in order to facilitate entry of the lading tie 67 through the space 70 into the cavity 61. The lower end surface 72 of the upper post 68 is of convex shape and faces downwardly over upper end surface 73 of the lower post 69 which is concave and faces upwardly and also is located along an incline 75 for the purpose of receiving the bght 76 of the lading tie 67 in the loop formation and permitting entry into the cavity 61 as shown near the lower portion of FIGURE 7. Such entry is further facilitated by having the lower rear side 78 of the upper post 68 inclined upwardly. The rear surfaces 80 and S1 of the upper and

lower posts

68 and 69 are ilat and coplanar.

In order to make certain that the bght 71 of the lading tie 67 in loop formation overlies the rear surfaces 86 and 81 of both the upper and

lower posts

68 and 69, as shown near the center of FIGURE 7, the upper post 68 is provided with an inclined upper surface 82. It will be understood that the lading tie 67, when applied as indicated at the lower portion of FIGURE 7, overlies the inclined upper inner surface 82 in order for the lower side of the lading tie 67 to clear the upper end of the lower post 69. When in this position on application of tension force, the inclination of the surface 82 is such that the lading tie 67 will slide over it and past a step 83 at the lower edge whereupon it will bear against the

rear surfaces

80 and 81 of the upper and

lower posts

68 and 69 as shown near the central portion of FIG- URE 7.

After the loop in the lading tie 67 is inserted, as shown in FIGURE 7, the lading tie 67 is swung toward the

side wall plate

64 or 65 and preferably is positioned at an angle not greater than 18 away from the inner wall surface in being extended around the lading. Thus, the major component of the tension stress applied to the lading tie 67 is along the car wall.

By providing the upper and

lower posts

68 and 69 and arranging for the lading tie to react against both of them, the tension stress applied to the lading tie 67 is distributed over the two posts. Since the space 70 is centrally located with respect to the cavity 61, there is no likelihood that the lading tie 67 will fall out of the cavity 61 should it become slack.

Because of the concave and convex surfaces at the lower and upper ends of the upper and

lower posts

68 and 69, respectively, a lading tie in the form of a wire can be used of such a diameter that it can pass through the space 70 but which will not be pulled therethrough even though it registers generally with the ends of this space since portions of such a wire will overlie the lowermost part of the upper post 68 or the upwardly extending parts i of the lower post 69. Ordinarily, such a lading tie, when slack, extends around the lower post 69 and thus is prevented from dropping out of the anchored position.

Since certain further changes can be made in the foregoing construction and different embodiments of the invention can be made without departing from the spirit and scope thereof, it-is intended that all matter shown in the accompanying drawings and described hereinbefore shall be interpreted as illustrative and not in a limiting sense.

What is claimed as new is:
