The invention relates to the bracing of loads in the load carrying compartments of freight cars or similar vehicles wherein it is desired to secure the load against shifting during transit, and the primary object of the invention is to provide anchor members which will enable an eflicient temporary bracing of the above character to be readily and economically applied and removed, and avoid the likelihood of injury to the walls of the compartment, or to the operative in applying and removing the bracing. Further objects and advantages of the invention will be in part obvious and in part specifically referred to in the description hereinafter contained which, taken in conjunction with the accompanying drawing, discloses suitable ways of carrying the same into effect; such disclosure, however, is to be regarded merely as illustrative of the princlples of the invention. In the drawing- Fig. 1 is a perspective view of the interior of a freight car compartment having load bracings applied thereto in accordance with the invention.

Figs. 2 and 3 are also perspective views illustrating somewhat more ramifled ways of carrying out the invention.

Fig. 4 is a plan view of one form of face plate adapted to be used in carrying out the invention.

Fig. 5 is a section on line 55 of Fig. 4.

Fig. 6 shows a simple form of anchor which may be conveniently used to engage the ends of lengths of flexible metal strapping detachably with face plates of the form shown in Figs 4 and 5.

In Fig. 1 the invention is shown as applied to the bracing of a load I against the end wall 2 of a freight car compartment. The side walls 3 and 4 of the car are shown as provided with a plurality of fixtures or anchor members constructed in accordance with the invention. These fixtures or face plates are permanently set into the walls of the compartment'and lengths I of flexible metal box strapping are detachably engaged in suitable manner (one device suitable for the purpose being later described in detail) with conveniently located face plates 6. The lengths of strapping I thus anchored to the compartment, are then tightened up with respect to the load I to be braced, and tied in tightened position. In the form shown in Fig. 1, what may be termed the central ends of the lengths l of strapping overlap across the inner face of the load I, and may be tightened up by means of tensioning mechanisms such as are already known and available in the box-strapping art, and a seal 8, also as heretofore employed in the box strapping art, may be applied by such mechanism to tie the tightened lengths of strapping together; or if the strapping be in the form of wires, wire-tying mechanisms as known in the art may be employed for the above mentioned tensioning and tying purposes. Fig. 1 shows two bracings of the character above described, applied to the load at different levels.

To disconnect the bracing it is merely necessary to cut the strapping I which is so inexpensive that it may be thrown away and new lengths employed for bracing the next load to be carried. Once the tension on the strapping isreleased, it may be readily disengaged from the flxtures or face plates 6, leaving the latter in proper condition to receive the next strapping to be applied. These fixtures 6 constitute the only permanent bracing equipment, and the operations of installing and removing the bracing therefore are simple and inexpensive; and avoid the likelihood of injury to the walls of the compartment, such as frequency has happened in the past where tenrporary bracings of a make-shift character have been nailed to the walls of the compartment with the likelihood of injury thereto, as well as to the operatives or the material being shipped.

Fig. 2 shows a somewhat more ramifled form of applyingthe invention wherein lengths 1a of flexible metal strapping are engaged at one end with the fixtures 8 and tied at their remaining ends to a metal rod 9, to which latter supplementary pieces of strapping lb are then secured at one-end. The ends of the pieces of strapping lb may then be passed around the load to be braced and engaged with similar pieces of strapping (not illustrated) coming from the opposite side wall of the car, and tightened and tied in the same manner as is above described in respect to the inner ends of the starpping 1 shown in Fig. 1.

Fig. 3 illustrates another somewhat more ramifled application of the invention which is particularly useful in refrigerator cars and other constructions in which the face plates 6 should be confined to certain restricted locations, in order to avoid impairment of special wall constructions such as the insulation used in refrigerator cars. In Fig. 3 two of the face plates 6 are shown at the right attached to the door frame of the car, and two more adjacent the ice bunker 2a at the end of the car. Lengths of strapping 1c may then be attached, for example, to the upper face plates 6 of Fig. 3, having their adjacent ends tied together by a seal 8w similar to the seal 8 above described, in such manner that the composite piece of strapping thus formed lies substantially Ampplcmentaty totheeenl thenbetledtothelormotthea aeallwatanypolnt andtbe wall thecar. it above deacrlbed.
