Oakley, Livonia, Mich., assignor, by mesne assignments, to MacLean-Fogg Lock Nut Co., Chicago, Ill., a corporation of Delaware Continuation of application Ser. No. 759,459, Sept. 8, 1958. This application Apr. 15, 1964, Ser. No. 359,917 7 Claims. (Ci. 105 369) This application is a continuation of my application for United States Letters Patent, Serial No. 759,459, liled September 8, 1958, now abandoned and entitled, Freight Car Wall Structure Including Series of Lading Strap Anchors.

This invention relates to lading strap anchors for the inner wall structure of freight cars and the like.

One of the objects of this invention is to provide a multiple lading strap anchor for the inner wall structure of a railway box car or the like, wherein said anchor is secured directly to structural parts in the car wall and wherein said anchor serves as a support for the securement of metal lining panels of the inner car wall.

Another object of this invention is to provide, in an inner wall structure for railway freight cars and the like, a multiple type lading strap anchor embodying a series of unitary sections which each include a plurality of lading strap anchors and which are securable in an end-toend and over-lapping relationship to one another to pro- Vide an inner wall strip of desired length having a series of lading strap anchors spaced therealong.

As another object, this invention comprehends an endto-end series of lading strap anchors which series forms a portion of the inner wall surface of a railway freight car and the like, and serves as a support and securing element for other parts of the inner car wall.

As a further object, this invention provides a lading strap anchor including a plurality of openings at which it is securable to the face of a structural element of a car wall from within the car and which has side support means to which wall elements may also be secured from the interior of the car.

Another object of this invention is the provision of a multiple lading strap anchor which includes means for supporting and securing other elements of the inner wall of a railway car, wherein said multiple lading strap anchor is made as a unitary forging.

Yet another object of this invention is to provide an inner wall structure for railway box cars and the like and wherein multiple-type lading strap anchors are secured directly to structural posts in the car wall, and which lading strap anchors serve as supports for the securement of metal lining panels of the inner car wall.

These and other objects and advantages of this inven-V tion will be apparent from the following description of a preferred embodiment thereof when taken together with the accompanying drawings in which:

In the exemplary embodiment of my invention which is shown in the accompanying drawings for illustrative purposes, a wall structure is shown in an adaptation to a railway freight car 10 which includes ooring 12, end walls such as 13, a roof 14 and a door opening 15 in the mid portion of a side wall 16.

In the hauling of many kinds of freight, in the loading and unloading of cars With freight and in securing lading in place within the cars, the inner lining is subjected to very rough usage, and cars consequently have to be re-` lined many times. To protect the more greatly abused lower portions of the car side walls, metal lining panels are increasingly provided for these portions of the inner lining surface of the car. These metal lining panels, such as steel plates, make it impossible to nail lading securing elements thereunto and necessitate .a wall structure embodying both lading strap anchors and metal panels with secure means for holding each in place.

The freight car depicted in FIG. 1 embodies metal panels 17 which extend to a predeterminedand desired height 18 on the car wall. As is customary in car wall construction, the 4illustrated wall includes structural support posts 19 in spaced relationship longitudinally of the car wall and a door post 20 defining one side of the door opening 15. Exteriorly of the car, the structural posts 19 and the door post 20 are covered by metal sheathing 22. Above the metal panels 17 on the interior of the car wall and interiorly of the structural postsI 19, the wall may be covered with a suitable material of less durability and less weight than the metal panels, such as plywood 23, although the metal panels may be extended to positions nearer the top of the car, if it is considered desirable. Each of the metal panels 17, in the disclosed structure, bridges the space between adjacent structural posts 19 in the car, or the space between the structural posts 19 in the car, or the space between the structural post 19 and the door post 20.

In order to afford lading strap anchors at desirable positions on the inner walls of freight cars and the like, for anchoring lading even though metal lining panels are utilized, and to facilitate the installation and securement of metal lining panels at desired portions of an inner car wall structure, I have provided multiple-type lading strap anchor units 24 of the kind illustrated in FIGS. 2 to 9 inclusive. Each such multiple-type lading :strap anchord unit, as herein depicted, constitutes an integral structure, which has width suicient to overlie an inner face, such as 25, of a structural support post 19 of the car wall structure and a length such that it covers a substantial portion of the structural support post and embodies a plurality of lading strap anchor posts 26a in spaced relationnship longitudinally of the structural support post.

In the form illustrated, the lading strap anchor unit has a front face 27, with which the lading: strap anchor posts 26a are substantially flush and a rear face 27a, said lading strap anchor posts extending rearwardly beyond rear face 27a andhaving rear mounting faces 28, which engage the face 25 of a structural support post when the unit is mounted thereon. Each posts 26a has an opening 3 29 formed therethrough from the front face 27 to the rear face 28, and has a tongue 26 extending downwardly over said opening 29. Said tongue 26 is smaller in the plane of front face 27 than opening 29, so thatl at opposite sides and at the lower end of each tongue 26, there is space for connecting a looped lading strap or other suitable tie to said tongue. This opening'also provides space along opposite sides and at the lower portion of said opening through which the lading strap anchor unit may be secured to face 25 of a structural support post in the car wall by welding, as at 30. The said space provided by opening 29 is large enough to make possible the welding of the unit to a support post from the inside ofthe car.

Each tongue 26 is spaced inwardly of the car from the rear mounting surface 28 of post 26a to provide space behind the tongue for receiving the lading strap (not shown). Also, at the opposite sides of each tongue 26, a side surface 32 of the opening 29 diverges outwardly toward the interior of the car to facilitate the application of weld material to the post 26a and the supporting post surface 25, and additionally to avoid the necessity of bending a lading 4strap abruptly as it passes behind tongue 26 and then laterally outwardly of the unit 24. The preferred thickness of the unit for minimum weight is that shown in sections 33 and 35 in FIG. 3, and the unit is reinforced by a transverse rib 34 located substantially midway between adjacent posts 26a and extending substantially from side to side of the unit, and by a transverse rib 34a located near the bottom end of the unit. Said ribs 34 and 34a extend rearwardly to a co-planar position with respect to posts 26a so that said ribs not only serve to stiffen the sections between posts 26a, but provide additional bearing surfaces to support the said sections directly from the surface 25 of the structural posts of the car.

At the lower end of the lading strap anchor unit, a downwardly projecting flange 42 is provided which is offset rearwardly of front face 27 and is coplanar with and connected to both sideflanges 36. At the upper end 40 of the lading strap anchor unit, side flanges 36 terminate a distance below the edge of said upper end 40 substantially equal to the width of flange 42 so that when a series of lading strap anchor units is mounted along a single structure support post of a car wall in end-to-end relationship to one another, end 40 of one unit overlaps the flange 42 of the adjacent unit.

To facilitate the use of the lading strap anchor units vwith metal lining panels, and to afford structure for supporting and securing such metal lining panels in place along at least one edge of each panel, the disclosed lading strap anchor units are provided with side flanges 36 which extend longitudinally of the opposite sides of each unit and project laterally therefrom. The side flanges 36 are offset rearwardly from the front face 27 of the lading strap anchor unit by substantially the thickneess of one of the metal panels 17, so that when a metal panel overlaps the flange and is supported thereby, the face of the metal panel is approximately flush with the front face of the lading strap anchor unit. In addition to the flanges 36 for supporting the adjacent metal panels, bevelled or recessed side marginal portions 37 are provided at positions spaced between the lading strap anchor posts 26 and adjacent the flanges 36 to provide space for welding the panels to the opposite sides of the mid portion of the lading strap anchor unit, as shown at 37a in FIG. 7. Likewise, adjacent the opposite end portions of the flanges '36, recessed or bevelled side portions 38 and 39 are provided to afford space for welding the metal panels to the end portions of the lading strap anchor units, as shown at 38a and 39a in FIG. 7.

To provide for welding the lading strap anchor units together in end-to-end relationship, bevelled or recessed end surfaces 43 are provided adjacent the lower end flanges 42 to afford space for welding, as at 43a in FIG. 7. When plywood lining, such as 23, is utilized above the 4 metal panels, such siding may be recessed, as at 44 in FIG. 8, to be overlapped by the upper ends 40 of adjacent lading strap anchor units, thereby to provide a closed joint and to aid in holding the plywood lining in place.

The lading strap anchor unit is shaped to adapt it readily to manufacture by a forging process. There are no re-entrant surfaces, and the recesses 37, 39 and 43, which are bevelled to provide space for welding, present surfaces which are well adapted for formation by forging dies. The edges of the flanges may be provided with an appropriate draft without creating undesirable spaces, or without requiring corrective grinding.

In the preferred form of lading strap anchor unit illustrated, the tongues 26 are disposed inward from the ends of the unit a distance equal to substantially one-fourth of the length of front face 27 so that when aseries of units 24 is placed end-to-end, said tongues 26 will be equally spaced from one another. Similarly, in such end-to-end disposition of the units, the combined length of adjacent recesses 3S and 39 is substantially equal to the length of a recess 37, and the combined recess 38-39 is located substantially midway between adjacent tongues 26 of adjacent units 24.

It may be noted that the rearwardly offset location of side flanges 36 and end flange 40 provides additional stiffness and strength along the side and bottom edges of the unit.

In installing the lading strap anchor units of the type disclosed and the adjacent metal panels, a number of lading strap anchor units which is sufficient to provide the desired length to correspond with the height of the metal panels of the wall, may be secured together in end-to-end relationship and the metal panels may be secured to opposite sides thereof to provide a sub-assembly which can later be secured in place against the structural support posts of the car wall as a unit.

While I have illustrated a preferred embodiment of my invention, many modifications may be made without departing from the spirit of the invention, and I do not wish to be limited to the precise details of construction set forth, but desire to avail myself of all changes within the scope of the appended claims.
