2 Claims. (Cl. 105-369) improved. construction of door post or framing post for. freight cars for facilitating mass production of 'a com posite post and lading strap anchor member in freight car construction. t

Another object of my invention is to provide a construction' of lading strap anchor member having coined depressions formed in spaced positions along the length.

thereof for providing passages for a lading strap, the anchor being welded to a door or framing post at opposite sides of each coined depression, all portions of the anchor being confined within planes co-extensive with the sides of the door orv framing post eliminating all sharp edges which might cause damage to the lading,

particularly where the lading consists of fragile Ipac'kages. 7 t V Still another object of my invention is to provide a composite lading strap anchor member and door A or- 0 4 training post for freight car construction wherein the lading strap anchor member is welded at spaced interstalled in accordance with my invention for securing lading adjacent the side doors of the freight car; Fig. 2

is a view similar to the view illustrated in Fig. l but illustrating a fragmentary portion of the freight car adjacent the center door openings thereof and showing particularly the versatility of the composite structure of my invention which enables the lading straps to be installed transversely of the freight car to form bulkheads or partitions rather than securing means at the open doors of the freight car as in Fig. 1; Fig. 3 is a vertical sectional view taken substantially on line 33 of Fig. 1 and illustrating the manner of installing the lacing strap between the composite door or framing posts and the lading strap anchor members associated therewith; Fig. 4 is a transverse sectional view taken on line 44 of Fig. 2 and illustrating the lading strap installed in position on the post showing the angularly inclined facethereof on which 7 the anchor strap, member of my invention is secured and showing particularly the manner of confining the end ofrthe lading strap at the commencement and end of the p vals along an angularly inclined corner surface Qfthe door or framing post where the portions of the lading- I anchor are coined in the spaces between the welds for offsetting the materialof the anchor to projected posi tions sufficient to provide openings for lading straps between the coined portions but restricted to positions not protruding beyond planes extending. coplanarwith ad jacent side walls of the door or framing post.

Another object of my. invention is to provide'a composite construction of lading strap anchor'member and door or framing post for freight cars where the lading v strap anchor nemberincludes coined portions spaced along the length thereof and forming slots for the pas- I sage of lading straps with the anchor welded to the post adjacent opposite ends of the coined portions and wherein the material of the anchor on oppositesides of the coined portions is displaced to positions which aresub stantially tangent to planes extending coincident with adjacent side walls of the door or framing posts;

Other and further objects of my invention reside in a practical construction of composite lading strap anchor. member and door or framing posts for freight cars which is capable ofinexpensive production and assembly in mass production of freight cars, asset forth more fully in the specification hereinafter following by reference to the accompanying drawings, in which:

-My invention is'directed to a composite structural unit' of door or framing post'and a coined lading strap anchor I member for freight "carswhere the coined lading strap anchor-'member is so associated with an angularly dis posed corner surface of the door or framing post that the lading strap anchor member does not project beyond adjacent faces of the door or framing post. Moreover,

the structural unit of my invention presents a surface to the lading which is free of sharp edges, thereby preventing damage to the lading particularly where the lading consists of relatively fragile packages. The lading strap anchor member is readily formed inexpensively and rapidly on a mass production scale by coining the lading strap anchor member in spaced intervals for displacing the material thereof at spaced intervals to provide sutficient space between the inclined wall of the door or fram- Patented Nov. 6, 1956' ing post. andthesaid member at the coined positions therein for thepassage. of a lading strap, the saidmember.

being welded to the inclined surface of the door or corner post at each endof the coined portions thereof The lading strap anchor member is so positioned with respect to the inclined wall surface of the dooror framin-gpost that planes drawnsubstantially tangent to the surface of the coined portion of the lading strap anchor member substantially coincide with pianos through the surface of adjacent side wallsof-thedoor or framing post By this arrangement the composite door or framing post and lading strap anchor member may be utilized in installing partitions or bulkheads across the door openings and/ or transversely of the freight car.

Referring to. the drawings in detail, reference character 1- in Fig. 1- designates a conventional freight car loaded withthe lading which I have represented at 2; and which maybe packed-entirely acrossithe side door openings 3 and 4-of the freight car. The composite door or framing post and lading strap anchor member has been shown installed at

positions

5, 6, 7 and 8 in Figs. 1 and 2. The structure of' each composite door or framing post and lading strap anchor memberis symmetrical and for purposes ofexplaining the construction in Fig. 7', post 8 is represented-as typical of each of=the illustrated positions. In Fig. 71 haye shown the door or framing post at 9 comprising a vertically extending metallic section projecting from thebase structure of the freight car to the roof structure thereof and comprising a linear section of approximately lsl shaped contour with one side exceeding the length of the other side forming a pair of substantially parallel extending spaced side walls 10 and 11 interconnected by end wall 12. The end wall 12 consists of a portion 12a extending normal to the side walls 10 and 11 and "a portion 12b extending at substantially 45 degrees to the surface ofend wall 12a and side wall 11. The position-ofthe angnlarly disposed portion 12b of the end wall isselectedin coordination with the mounting of the lading strap anchor member 14 to enable the door or framingpost to be used either as a part of, the side door structure of. the freight car or as part of a transverse partition across the freight car. That is to say, the corner of the door or framing post 9 is mitered and the lading strap anchor membersubstantially fills the corner portion but does not project beyond the limits defined by planes projected from the adjacent side and end wall ofthe door or framing post. The openings 15 areso disposed that the lading strap can be directed into the door orframing post from a direction substantially. coplanar. either with the end or adjacent side wall of the door b framing post.

The lading, strap anchor member 1 comprises a circular steel bar ofapp'roximately diameter for a door Orfra'mingpQSt having a transverse width of 3 across the vexternal faces ofsidewalls 1t) and 11. The dimenw sional proportion forthe width of the end wall portionofthe ,bar;for a distance of approximately. providing an- .openi ng15, 15a, 15b; 15c, etc. sufficient for the insertion andpassage ofa lading strap. The lading strap maybe a, ,band vof flexible metal or stout interwoven hemp. The lading strap anchor member 14 is welded to thelcenter of- -the inclined end wall 12b on each side of the coinedxdepression as represented at 16 and 16a for securingthe lading strap anchor member in a ppsition ihede ma o o he c on; f he aLhQwe e s;

restrictedin one directiontovai plane coincident with the external surface 14 of the lading strap anchor mem-. ber 14. the lading strap anchor member 14 are restricted to positions which do not protrude beyond planes coincident with the end. wall portion12aand the side wall 11 of the door or framing post 9. Inthe preferred construction of my invention the enlarged projections 14a and 14b of the lading strap anchor member 14 are formed on curves with respect to which planes extending from the external surfaces of'the end wall portion 12a and the side wall 11 are substantially tangent. I have found this construction particularly effective in eliminating sharp edges or obstructions which can cause damage to the lading.

The interior surface of the side walls 10 and 11 0f the door or framing post 9 are interconnected by a transverse plate 17 welded thereto at each end of the plate. The reenforcement means for the side wall structure of the fright carhas been shown generally at 18, 19 and 20 i to which the door or framing, post 9 is secured by bolt member 21. The side wall of the freight car is represented at 22 extending over the reenforcement means 19 and over the sidewall 142 of the door or framing post 9.

The lading strap is shown at 23 in Fig. 3 laced through the

openings

15, 15a, 15b, 150, etc. between the door or framing post at positions 5 and 6 for protecting lading against shifting adjacent the

door positions

3 and 4. In Fig. 4 I have shown the manner of utilizing aligned. door or framing posts at positions 5 and 7 for lacing the lading strap 23 transversely of the. freight car and providing a partition or bulkhead for preventing the shifting of the lading intothe transverse space at the door positions of the freight car. The lading strap 23 islooped through the opening 15 in the ladingstrap anchor member 14 adjacent the top of the, freight car as represented at. 25 in Fig. 5 andrthe end of the ladingstrap secured upon itself by useof a special tool that pullsthe adjacent aligned portions ofthe' 'strap tight and in a second operation applies and crimps a securing band26 transversely of the straps. The ladingstraps are laced horizontally as shown with their ends extending through the openings 15 in the ladingjstrap member 14. as represented in Fig. 6. Each lacing is made individually and thefree end of the lading strap represented at 25 in 'Fig. 5 secured to the adjacent aligned portion of the strap 23 by thecrimping tool which squeezes the aligned portions of the strap together as shown at 26. In Fig. 51 have shown but one end of the lading strap 23 secured by the cross band 26, but it will be understood thatthe opposite end of thelacing strap is the straps are individually applied.

The angularly disposed endwall 12b for each of the door or framing posts serves as apocket for. the mounting of the lading strap anchor member 14 in such position that minimum obstruction is offered toloading and un loading operations dnring the frequent ingress and, egress it be understood that no lirnitations upon my invention are I intended other thanmay be imposed by the scope of theappended claims,

The projecting side portions 14a and 14b of" What I claim as new and desire to secure by Letters Patent of the United States is as follows:

1. A composite door post and a lad-ing strap anchor member comprising a vertically extending metallic member having a pair of substantially parallel side walls and an end wall angularly mitered at one corner thereof and a lading strap anchor member attached to the mitered corner of said metallic member and having bodily displaced portions disposed at spaced intervals along the length of said anchor member, said displaced portions being directed away from the surface of the corner of said metallic member for providing spaced openings for the passage of a lading strap between said anchor member and the mitered corner of said metallic member, said lading strap anchor member being of substantially circular section with the bodily displaced portions transversely enlarged at said spaced openings and formedion curves with which planes contiguous with the end and the side wall immediately adjacent the mitered corner of said metallic member are substantially tangent.
