Oakley, Chicago, Ill., assignor to MacLean- Fogg Lock Nut Company, Chicago, 111., a corporation of Illinois Application June 14, 1954, Serial No. 436,525 5 Claims. (Cl. 105-369) This invention relates to anchors for lading straps and the like, and more particularly to an anchoring device for the securement in place of objects of lading relative to the floor of a flat car or the like by straps or ties which may extend from the anchoring devices in any of a plurality of transversely related directions.

It is a general object of the invention to provide an improved anchor for lading straps and the like suitable for use in the floors of railway cars or in other installations where it is necessary or desirable to utilize straps or ties for the securement of lading and in which installations the securement of lading may require straps or ties which extend from the anchoring devices in either or both of transversely related directions.

It is a further object of the invention to provide an anchor for lading straps and the like which has parts so constructed and arranged that a single such anchoring device will accommodate various straps or ties that may extend in different directions simultaneously for the securement in place of objects of lading.

A further object of this invention is the provision of an anchoring device for lading straps and other lading ties which, in view of its multi-directional character, is unusually suitable for a lading area of limited space such as is found in the floor area of a railway car in that a fewer number of such anchoring devices is necessary to secure variously shaped objects compactly in the lading area.

A still further object of the invention is the provision I of an anchor for lading straps and the like which provides ample and convenient tie facilities with a minimum of alteration or installation expense and without a substantial lessening of the supporting strength of the floorp ing in the lading area.

It is another object of the invention to provide a 'multi-directional anchor for lading strapsor ties which may be advantageously employed in lading areas such as in a railway flat car floor, wherein the anchor is. subjected to heavy strains and where it is exposed to detrimental weathering conditions such as ice, snow, ,rain, and dirt.

It is a further object of the invention to provide a multi-directional anchor for lading straps and the like which is of open construction, so as to facilitate the attachment of ladingstraps and ties thereto and so as to maintain the anchoring device in a clean and usable condition at all times.

It is a more specific object of the invention to provide a multi-directional anchor for lading straps and ties which may be readily and conveniently applied to railway cars having either wood or metal flooring. A further object of the invention is the provision of a multi-directional anchor for lading straps and the like flexible lading straps and ties to the floor or underframe Patented Mar. 10, 1959 further indicating the application of lading straps to the anchor;

Having reference to the accompanying drawings, wherein exemplary embodiments of my invention are disclosed for illustrative purposes, it will be seen that a multi-directional strap anchor 10 embodying my invention is readily adapted for use with a railway car floor construction 11. While the improved anchoring device 10 would generally be incorporated in a railway car during the course of construction of the car or when applying new flooring to a used car, its design and arrangement are such that the anchor may be conveniently and efficiently installed at any time as will be hereinafter more fully described.

It is customary in providing lading strap anchors on railway flat cars to locate such anchors in rows aligned laterally and longitudinally of the car floor, that is, along .each side of the center sill at end regions of the car fioor. In this arrangement, the straps and ties for the holding of objects of lading and which provide lateral securement are attached to the anchor rows adjacent the center sill and extend in a direction lateral to the length of the car, while those providing securement longitudinally of the car or at the end anchor rows extend in a direction longitudinal of the car. With the multi-directional anchor embodying my invention it is necessary only to have a sufiicient number of the anchors for adequate securement of the lading without reference to the necessity of providing for extension of lading straps and ties either laterally or longitudinally of the railway car.

Referring in greater detail to the multi-directional lading strap anchor as shown in Fig. 1 and apart from its incorporation in a railway car floor, the anchor 10 comprises a support or supporting frame 11 which is a substantially rigid structure, and which, for convenience of fabrication and assembly of the anchor, is made of two generally U-shaped frame sections 12 and 13 of relatively heavy strap metal with the ends of the U-shaped pieces butted and welded together, as at 14 and 16, to provide a rugged and practically rigid frame of generally rectangular shape. The width of the metal strap material in the frame is desirably such that it extends at least through an opening such as 17 in car flooring 18 when'mounted in flush relationship to the top of the floor. As thuscon- .structed, the frame 11 provides a plurality of vertical Wall portions which enclose a center space or opening 19.

Across the mid-portion of the center space 19, as defined by the supporting frame 11, a substantially rigid metal tie post 21 extends, which tie post is an integrally forged cross-shaped structure or one fabricated from bars but welded together and is secured to the frame by plug weld 22, to frame sections 12 and 13, thereby to further increase the strength and rigidity of the supporting frame. The tie post 21, as shown in Fig. 1, has crossarms constituting tie post portions 21a, 21b, 21c and 21d, such tie post portions being joined together to form a central hub-like juncture 24. The tie post, having this cross-like configuration, is adapted for the attachmentof lading straps or ties 26 to one or more of the tie post portions 21a, 21b, 21c and 21d, as indicated by the dotand-dash lines in Figs. 1 and 3. The tie post 21 for convenience of use, is located adjacent the top of the supporting frame 11 with the tie post portions spaced substantially from the wall portions of frame 11, so as to facilitate attachment of the lading straps 26.

in the multi-directional anchor as illustrated, two of the tie post portions 21a and 21d adjacent and at right angles to each other are of greater length than the two opposite portions 21b and 210, which latter portions are also adjacent and at right angles to one another. This structural arrangement is advantageous in enabling lading straps of varying widths to be anchored in either of two laterally disposed directions withoutslippage and, also, to promote ease of attachment of the lading straps to the anchor.

When constructed as shown in Figs. 1, 2 and 3, the multi-directional anchor embodying my invention will enable at least four lading straps 26 to be attached to the anchor with each strap, if desirable, extending from the anchor in a different direction. This increases greatly the combinations possible for the loading and securement of objects of lading in a given area over that provided by an equivalent number of uni-directional anchors. This greater availability of loading combinations naturally results in eflicient use of available anchors and in decreased time of loading as well as increased compactness of the lading.

In the incorporation of the multi-directional lading strap anchor in a standard railway fiat car having a Wood floor supported by the car underframe, the opening 17 ismade in the flooring 18 and is of a size approximately that of the outside dimensions of supporting frame 11. As shown, the opening 17 may be made at the .juncture of two flooring elements so that such opening extends partially into each of the adjacent flooring elements, thereby avoiding the excessive weakening of any single flooring element. Securement of the anchor 10 to the railway car-floor construction may, of course, be made to the wooden floor 18 but for greater strength and solidity, attachment is preferably made either to the car underframe 27 or to strong metal angle strips 28 on opposite sides of the frame 11, provided for that purpose, and which, in turn, are secured to the car floor 18 by fastening means, such as bolts 29.

- In the type of mounting shown in the drawing, two metal angle strips 28 extend under thefiooring in adirection transverse to'the length of the flooring elements and adjacentthe edges of ilooropening 17. .T he angle strips 28 have arms or flanges secured .to the :car flooring :18, as by bolts 29. It is desirable to have the angle strips extend considerably beyond the floor opening 17 so as to afford greaterstrength to the flooring and thus compensatefor any weakening of the floor as a result ofthe opening 19.

As has been previously pointed out, the width of the material of the supporting frame 11 is such that the anchor extends at least through the opening 17. The lower edge of the anchor 10 wil thus lie adjacent and engage the angle strips 28 to which it is secured as by weld joints 31. Securement of the anchor 10 to the angle strips 28 provides a strong and substantially rigid attachment which, of course, is of importance considering the function of the lading strap anchor. This manner of securement is of particular advantage where the lading strap anchor is being installed in railway car structures at positions spaced from the under-frame parts. Where the railway car construction and the desired location of the anchor permit, securement of the anchor '10 may be H made directly to the car underframe, thereby eliminating the need for one or both of the angle strips.

A modified form of my multi-directional lading strap anchor is depicted in Figs. 4, 5 and ,6, and has a tie post which is of a construction that enables lading straps secured to it to be extended in the directions of either or both of two transverse planes, such directions being generally perpendicular to each other. As illustrated, this form of lading strap anchor 10 includes a substantially rigid tie post 41 secured to supporting frame 11 as by plug welds 42. The tie post 41 is of a general L-configuration the .angularly disposed leg portions of which con- .stitute tiepost portions 43a and 43b to which lading straps- 46 may be attached, as shown in Figs. 1 and.3 by the dot-and-dash lines. The tie post 41 is located adjacent the top edges of the supporting frame, so thatthe lading straps may extend therefrom at a wide variety of angles without effecting any bends or kinks in the lading strap which would be detrimental to its strength. The tiepost portions 43a and 4312 are, of course, spaced substantially from the wall portions of frame 11 which extend in substantially parallel relationship thereto, so as to facilitate insertion and attachment of the lading straps. The supporting frame 11 for tie post 41 is similar to that used in the preferred embodiment of the invention as -is the manner of securement of the modified lading strap anchor to the railway car floor construction. Whenincorporated in a railway fiat car, the L-shaped tie post 41 will enable ties from a single anchor to be made-simultaneously both laterally and longitudinally of the length of the fiat car.

In the attachment of lading straps 26 and 46 to tie posts 21 and 41, as shown in Figs. 3 and 6, the lading strap is turned back or bent at one end and the bent portion inserted or forced downwardly between the tie post portion 'to which it is to be aflixed and the adjacent wall portion of supporting frame 11. After the end of :the ,lading strap has passed the tie post portion, it springs or .is moved toward or against the opposite wall portion of the supporting frame and is then pulled upwardly to be secured to the main part of the lading strap. Such attachment is facilitated by the lading strap anchor 10 beingopen at both ends, so that no limitation is placed on the downward movement of the strap as it is being attached.

The advantages resulting from the lading strap'anchor 10 being open at both ends include that of the anchor being self-cleaning in that foreign objects and debris will pass through the center space or opening 19 defined by the supporting frame 11. This is of particular desirabil- :ity for lading strap anchors used on railway flat cars where they are exposed to adverse weather, ice, snow, rain, and the like, as well as to dirt. By the anchor 10 being open and clean at all times, cleaning out operations preliminary to attachment of the lading straps areelimihated and a'longer life and wear of the anchor and'the adjacent car structure are assured.

The lading strap anchors embodying tie post 21 and tie "post 41 are both multi-directional in that they xenable lading straps .to be extended from the anchors :in a plurality of directions simultaneously. This results from each of the tie post portions 21a, 21b, 21c and 21d and portions 43a and 43b being angularly disposed with respect to its adjacent portion, such angle, of course, causing the lading straps to extend outwardly from the anchor in different directions. In the embodiments shown in the drawings, the angle is approximately 90 degrees which effects a similar angle in the extension of the lading straps. In the lading strap anchor utilizing tie post 41, the tie post may be considered as being of a single length having a 90 degree angle midway of the length and with the two segments of the single length extending from such angle to the wall portion of the supporting frame as constituting tie post portions 43a and 43b. It is, of course, possible to use a tie post of a single length having one or more angles of varying degrees if such is desired.

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 constructions set forth, but desire to avail myself of all changes within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
