Additional objects of my invention will be brought out in the following description of a preferred embodiment of the saine taken in conjunction with the accompanyin drawings, wherein Figure l is a three dimensional view of a single section binding strap anchor means embodying the features of the present invention;

Figure 2 is a View in section through a wall of a freight car, as viewed on substantially a 45 angle, and depicting one manner of installation of the device of Figure l;

Figure 3 is a View in section taken in the horizontal plane through the horizontal center line of the crossshaped cut-out of Figure 4;

Figure 4 is a view depicting the manner in which binding straps may be anchored;

Figure 5 is a schematic view of the interior of a freight car to illustrate a suggested arrangement of' binding strap anchor means of the present invention into the wall construction of such a car.

Referring to the drawings for details of my invention in its preferred form, the binding strap anchor means may comprise one or` more hollow sections 1 of shallow rectangular cross-section, and preferably formed of sheet metal of a gauge sufiiciently heavy to withstand the stresses to which the anchor means will be subjected in use. In such form, the anchor means involves a base strip 3, a face strip 5, both joined in spaced relationship to each other by side walls 7 and 9.

Each such face strip has at least one cut-out 11, preferably of cross-shape located intermediate the ends of such section, to form four

anchor tabs

13, 15, 17 and 19 behind any successive pair of which, one might slip a sub stantially rectangular conventional anchor plate 21, such, for example, as is disclosed in my patent for Binding Strap Anchor Means, No. 2,581,529 of January 8, 1952. The cross-shaped cutout is preferably disposed so that one arm extends transversely of the face strip, preferably from one side wall to the other, with 'the other arm extending longitudinally of the section. When so disposed, there results two longitudinal pairs of anchor tabs and two transverse pairs.

When the anchor means comprises but a single section, the face strip is provided at each end with a notch 23 of width suflicient to permit of the withdrawal of a binding strap. When the anchor means, however, comprises two or more of such sections in series, such end notches will match up with adjacent end notches of` adjacent sections to form rectangular cut-outs 25 intermediate the cross-shaped cut-outs in the face strip.

The conventional anchor plate is a flat rectangular i piece of metal having a rectangular slot 27 therein through which to thread one end of a binding strap 29 to form a loop 31, which when folded about the anchor plate, will result in the loose end of the strap loop being snubbed against the plate and security held against slipping when tension is placed on the strap.

ln utilizing such anchor plate in connection with the anchor means of the present invention, the plate, after the strap has been threaded therethrough and snubbed in the manner indicated, is slipped into position behind any pair of adjacent anchor tabs, the particular pair of tabs selected depending upon which direction it is desired to lead the strap. If the anchor plate is to be disposed behind a longitudinal pair of tabs in order to lead the strap off in a lateral direction with respect to the anchor means, the proximate side Wall will act as a stop or abutment stesse for the anchor plate when tension is placed upon the strap,

When the strap is to be taken off tudinally of the anchor meansrby disposing theanchor plate behind a transverse pair of tabs, the freeend of.' the strap is first preferably passed through the cross-shaped. cut-out and snaked longitudinally of the interior. pas?.

sage of the anchor means untilgsuch free end .appears at one or another of the cut-outs along the face strip, through any desired `one of which the strap may be withdrawn until the anchor plate can be conveniently inserted behind the appropriate pair of anchor tabs.

- To preclude such anchor plate from -being pulled into the anchor means passage and out` of reach, stop means are provided which will notinterfere with movement or positioning of the binding strap. Such stop means may take the form of one or more tabs 33 'upset4 in a downward direction from'the -faceA strip-at appropriate points therein, though preferably such tabs are located adjacent the ends of the longitudinal arms of each crossshaped cut-out,to form longitudinal wall sections depending from the edges of such arms adjacent the ends thereof, and extending to the back strip. Such wall sections being then disposed edgewise tothe anchor plate, they offer maximum resistance to bending or tearing under the conditions to which they will be exposed in use. -By joining such wallsections to the backing plate, preferably as by welding, the strength thereof is not only enhanced, but the anchor means in general becomes strategically reinforced. A

The anchor means is preferably fabricated from a pair of intertting

channels

35, 37 welded along exposed contiguous edges, thus creating side walls of double thickness. l

The binding strap anchor means of the present invention may be built as original equipment or may be utilized in the lmodernization of old equipment, and has particular application-tov freight vehicles. such as railroad freight cars. In connection with one type of such freight which may be of heavy gaugesheet metal such as aluminum ory steel which is applied to and supported on the outer flanges of the ribs, while the innerV wall is aixed tothe surfaces provided by the inner fianges and the wood inserts. t

In incorporating` the present invention into the wall construction of such vehicle, a plurality of multiple binding strap anchor means are disposed horizontally in vertically spaced relationship across the inner flanges of the side wall ribs from Aeach end of the car to the doorway of each side Wall and welded to such flanges, following which the intermediate spaces between such multiple binding strap anchor meansy may be filled in preferably by -boards or siding 49 of thickness comparable to the height of the anchor means side walls, so as to present a flush surface in conjunction with the face strips of the binding strap anchor means. Such boards or siding may be fastened into position by nailing them to the wood inserts previously referred to.

The end walls of the car may be similarly constructed, with the anchor means arrangement on one end wall preferably `matching the arrangement of the anchor means on the opposite end wall of the car.

In lieu, however, of -applying multiple bindingstrap anchor means to the end Walls, it is contemplated that in some instances it would be preferable to utilize single in a. direction longi..

section anchor means, and when such are used, each will be disposed vertically along a rib and welded thereto at each end, thus strongly securing the same into the wall construction. The number and location of such single section anchor means in the end walls of the vehicle is determined with the View Of obtaining maximum utilization and efficiency. In fact, it may even be desirable to incorporate a number of such single section anchor means in the floor of the car, preferably adjacent the end walls thereof.

lt will be apparent, in view of the fact that the binding straps may -be takenoff `in any of four different directions from each cross-shaped cut-out, that the anchor means of the present invention, when installed in the side and end walls of a freight car or similar vehicle, provide facilities. for binding freight in one or more horizontal planes throughout the height of the car, as well as one or more vertical planes either transversely of the car or longitudinally thereof, thus making it possible to securely bind such freight against shifting in any direction.

The multiple binding strap anchor means, with its successive cross-shaped cut-outs, makes it possible to anchor the binding, straps at regularly occurring selected points along the car walls, and by spacing such take off points at frequent intervals, say of the order of twelve inches, the binding straps may be standardized as to length. The importance of this lies in the fact that no longer will it be necessary to follow the prior practice of xing the binding strap to a point on a side wall of the car and then run the strap out through the door of the vehicle to a length which the operator would have to estimate as suicient to meet the requirements of a particular cargo or shipment of freight to be stowed in that particular car. Y

Aside from the manner of use just described for the anchoring of freight n in a `car` or lthe like, the anchor means ofthe present invention offers facilities for suspending freight in air, that is at an elevation above the oor of the vehicle should the nature of the freight call for the suspension thereof in transit. This can be readily visualized by extending supporting straps from anchor means on one side wall of the vehicle to the corresponding anchor means on the opposing side wall to form a bed or sling on which to dispose the freight or cargo, which may thereafter be retained thereon, if necessary, by binding straps across the top thereof.

Straps anchored to binding means on the end walls might conceivably be interwoven with the transverse straps and crimped at their free ends to the transverse strap nearest the middle of the car, to form a reticulated network which would be much stronger and more efficient. Such flexible suspension of freight or cargo serves to point up the flexible character of the present system of anchoring freight.

A feature of the construction of the binding strap anchor means of the `present invention, lies in the fact that it is totally enclosed on three sides by the rear strip and the side walls, leaving the interior exposed only through the cut-outs in the face strip. The significance of this lies in the fact that in shipping bulk freight such as grain, the face strip, if desired, may be readily masked, but even if not masked, no such bulk material can gain access to interior of the car walls. Any such bulk material gaining access to the interior of the anchoring means, will for the most part, automatically flow out through the cross-shaped cut-outs since the transverse arms of such cut-outs extend to the side walls of the i anchor means. Any material remaining within the anchor means upon unloading of-a car, will be insignificant, and even this may be readily blown out with an air hose.

It` ,will be apparent from the foregoing description of my invention in its preferred form that the same is subject to alteration and modification without departing from the underlying principles involved, and while I have illustrated and described my invention in its preferred form and in considerable detail, I do not desire to be `limited in, my protection tosuChtdetaiIS-as I have :illustrated and described except as may benecessitated by the appended claims.
