(ci. 1ct- 356) lil Claims.

YEhis invention relates to anchor means for containers and particularly to anchor means for containers carried upon moving vehicles such as railway cars.

A considerable percentage of freight is now handled in small containers which may be lifted bodiiy with their contents from the road or rail vehicle and transported to the discharge point for unloading thereby obviating a large amount of manual handling. During transport of the containers in groups on rail or road vehicles it is absolutely necessary that the containers be held against shifting on the supporting structure. It is, of course, obvious that the higher a container may be gripped the easier it becomes to anchor the same to the supporting structure, but when high retaining means have been Used in the past it necessitated excessive lift of the containers to remove them from the transporting structure. As a consequence practically all high sided container carriers were provided with one or more sides capable oi holding downward, but with such a construction the sides could form no structural part of the car, that is, could not carry any load and the underirame had to carry the entire load imposed upon it by the containers. It is an object, therefore, of the present invention to provide a container car in which the entire side wall surface has a girder to carry the container load.

A further object of the invention is the provision of a low side rigid wall container car allowing removal of the containers without excessive vertical lift.

A still further object of the invention `is the provision of a container car of rigid low wall construction having means for gripping and positively anchoring the containers at relatively high points upon the container sides.

A yet further object of the invention is the provision of collapsible anchor means for containers and which anchor means locks all containers together longitudinally of the transporting vehicle.

Referring now to the drawings in detail and in particular to Figures l and 7, it will be seen that the container car has been illustrated as a railway car supported in any suitable manner upon trucks T adapted to run on rails or other supporting structure. The car is built as a side carrying car having plate side walls 2 attached to a top angle form chord l and a bottom an le form chord ii, thus forming a plate girder side wall. The plate girder side wall is connected adjacent its ends to holsters 3 and is also oonnected between the ends to cross bearers These bolsters and cross bearers are connected to built up sh belly center sills i2 having bottom angles i4 and cover plate l. Stringers i3 rest upon the holsters and cross bearers and support intermediate portions of the car liooring 2t which is supported at the center of the car upon center sill cover plate and at the ends upon plate girder side walls through the medium ci angle Portions of the car floor are cut away in order to accommodate stub center posts of cruciiorm cross section attached directly to the top cover plate of the center sill. rIhese stub posts are formed, as clearly shown in Figs. 1 and 3, of four pressings 24, 25, 26 and 2, each of general channel cross section, with the flanges welded together to form the cruciform center post. The pressings have the upper ends narrowed down to provide guide surfaces 28 and attaching portions for longitudinal channels 3Q and transverse channels 32. The ends of the transverse channels are attached to the upper ends of pressings Se attached to the plate girder side walls and to the angles 22 and of identical form with the individual pressings of the cruciform center posts. In this manner the car interior betweenthe plate girder side walls is divided into a plurality of longitudinal and transverse pockets bounded by channels 3@ and 32 and by side and center posts adapted to receive and guide the containers into place and prevent shifting of the lower part of the container.

The 'containers carried by the car may be of any desired form but in the present case are rectangular containers provided with discharge outlets in the bottom thereof. Containers as disclosed are built with a bounding framework et to which is attached side walls lli and inclined closed top portion d2. The bottom of the container is formed by converging walls ist providing in enect a hopper closed by any suitable hopper discharge gate mechanism or, if desired, equipped for discharge by air pressure. Gusset plates it are connected to the framework and to the side Wall structures as well as to the ends of upwardly diverging straps i8 anchored at their lower ends to the container framework. As clearly shown in the figures and particularly Fig. 2, the plates d and straps 48 are pierced to provide inclined elongated slots 59.

It will be seen from the preceding description that the containers will be securely anchored in the low side car at their bottom portions only and it will be obvious that the containers, unless otherwise anchored might be thrown from the car in case of derailment or excessive train shocks. Accordingly improved anchor means have been applied to the car for gripping the containers at points relatively high on the side walls. The anchor means, as clearly shown in the figures, consists of a plurality of cast or pressed anchor plates lili, having laterally extending arms Si formed on their ends with inwardly projecting lugs 62 adapted to t within inclined slots Eli, previously referred to. These anchor plates are also formed with an inclined part @d pierced to receive the threaded end of a long rod 55 extending transversely of the car and formed at its inner end with an elongated eye 63 adapted to engage over a pin it welded or otherwise secured to the side arms of a U-shaped bracket 72 welded or otherwise secured to the channels 3d and 32 at the center cruciform posts. The threaded part of these rods is provided with a nut i3 adapted to engage the inclined portion 6d of the anchor plate and the nut is held against loss by upsetting the threaded end of the rod. Each of the central anchor plates is also provided with a depending portion pierced as at 'iii to receive eye 75 formed on a substantially vertically extending rod i6. The lower ends of these vertically extending rods extend through openings in the top chord i and have their ends threaded to receive a nut 'Il held against loss by upsetting the end of the rod. Since the top chord is of bulb angle formation, small bearing blocks i8 are attached to the top chord beneath the web thereof in order to bring the nuts 77 in position for ready adjustment on the vertical rods it. In order to anchor the end containers end anchor plates Se are provided and each is formed as substantially a duplicate of half of the anchor plates GE? and accordingly, insofar as possible, the same reference characters have been applied thereto. In the case of the corner or end anchor plates, however, angular projections S2 are formed thereon to engage the end walls of the container and these projections are buttressed to the inclined portion iid by gussets 83. Also the projecting lugs Sli are mcdied to provide lips 35 adapted to interlock the corner plates and container, all as clearly shown in Figs. 5 and t'. These corner or end anchor plates are held in position by the saine type of transversely and vertically extending rods as were previously described in connection with the centrally located anchor plates and accordingly the same reference numerals have been applied thereto.

assvgiei The operation of the improved anchoring means is as follows, assuming the car to be in fully loaded condition as shown in Fig. 7 and with the anchor means in the positions shown at the right half of Fig. 1 and. by Fig. 2. Any authorized person desiring to remove the containers first backs off nuts 73 and 'il on the transversely extending and vertically extending rods, after which the central anchod plates @El and corner or end anchor plates dil may be disengaged from the slots 5d and allowed to drop. Dropping of the anchor plates will cause the parts to assume the full line position shown in the left hand part of Fig. 1 and the containers may now be readily removed from the car without excessive lifting. It should here be noted that when in a collapsed position the anchor eans cannot project beyond the clearance limits of the car and, therefore, cannot foul trackside obstructions in case the car is moved with the anchor means in collapsed position. During loading of the container car the containers are dropped into position and the anc-hor plates lifted until their lugs engage the inclined slots lill, after which nuts "i3 are tightened to hold the plates against the containers, then nuts il are 'tightened on rods l, pulling the projections G2 of the anchor plates downwardly in the inclined slots 5i? until the containers are tightly gripped and urged toward each other. This operation will place a small amount of slack in rod S3 and this must then be taken up by tightening nuts it. When the nuts 'i3 and "il are properly tightened the containers are held against Vertical lift by rods it and against outward movement by rods t6. Also the anchor plates dii, due to their lugs S2, securely tie the containers together longitudinally of the car and at a point above the top chord of the car wall. Accordingly, longitudinal shifting movement of the rows of containers is prevented. t will be obvious that the improved anchor means and container positioning means may be readily applied to existing low side gondolas merely by securing the positioning means in the car and attaching the anchor means thereto. Thus the railroads or their carriers can readily convert existing cars for use as ecient container carriers and without excessive material or labor.

While the invention has been described more vor less in detail with specic reference to the figures showing' one modication, it will be obvious `to persons skilled in the art that various other modiiications and rearrangements of parts may be made and all such modifications and rearrangements of parts are contemplated as will fall within the scope of the appended claims defining our invention.
