TRANSPORTATION UNIT.

Application filed May 10, 1921. Serial No. 488,397.

My invention relates to transportation systems in which carriers and shipping contamers are adapted to be assembled with each other to facilitate the transfer of merchandisc from one carrier to another or from warehouse to carrier, and vice versa.

The general idea of the system is shown in prior patents issued to me, for example, Patent Nos. 885,162, dated April 21, 1908,

997,300, dated July 11, 1911, 1,252,810,.dated January 8, 1918 1,349,209 dated August 10, 1920, and 1,360,412, dated November 30, 1920.

One object of my invention is to provide a shipping container which is adapted when 5 mounted on a flat car with similar units to form therewith a box car of approximately standard type.

Another object of my invention is to provide simple eflicient means for securing such a container in position upon a flat car or other carrier to prevent tilting or other movement of the container relative to the carrier. I

In the drawings which illustrate a selected embodiment of my invention Figure 1 is an end view of one of my con tainers' which may be used to form the end of a box car superstructure and which is mounted upon a .flat car sectioned in this view to more clearly illustrate the assembly of the container with the flat car.

Figure 2 is an enlarged detail of the container locking mechanism shown in Figure 1 Figure 3 is a top view of a plurality of containers assembled on a flat car and broken away in part to illustrate the holding mechanism below.

Figure 4='is a side elevation of the cont'ainers, nal section through the center of the flat car carrier.

Figure 5 is a detail view of a. modified form showing a disappearing form of looking device on the carrier.

Figure 6 is a detail view ofcertain parts shown in Figure 5.

Figure 7 is a perspective of a carrier with several units arranged thereon.

My container comprises a box-like structure adapted to extend across the entire width of a railway car and is provided with doors 2 on at least one side, which are adapted to swing outwardlyvfor loading and unshown in Figure 3 and a longitudiloading purposes. The top 3 of the contamer is antlclinal, or slo es downwardly in e ther direction from the ongitudinal center line to form a water-shedding roof and a runn ng board section 4 is mounted along the longitudinal center line of the container.

When a plurality of containers are assembled, as shown in Figures 3 and 4, sect1 ons 4 combine to form a continuous runnmg board throughout the length of the car.

My container is adapted to be.carried on motor trucks, railway cars, barges, etc., but 1n the accompanying drawings I have shown it only as mounted on a flat car carrier. This flat car is provided with the usual center sills 5, side sills 6, and floor 7. The container is provided with side feet 8 and central feet 9 and the floor 7 of the car has pockets to receive the container feet. At least two of the containers on each fiat car carrier are provided with ladders 10 on one face to enable the trainmen to mount to the top of the container. Similar ladders may be applied to one of the doors 2 or, where doors are provided in one side only of the container, to the blank side wall of the container.

To reinforce the end walls of the container I provide ribs 11 of structural or pressed plate section and preferably arranged as shown in Figure 1 in the form of an inverted W in which two of the braces lead from two

adjacent feet

8 and 9 diagonally upwards to a common'meeting point near the top of the container. Two other braces converge from the other two

feet

8 and 9 to a common point near the top of the container spaced from the meeting point of the first pair of braces. Lifting ears 12 are secured to the wall of the car and to braces 11 and form holding means for the hook of a crane or derrick which will be used for transferring the containers from carrier to warehouse, etc.

To hold the container on the carrier, I provide hooks pivoted to the underframe, which are adapted to extend into recesses in feet 9 and engage same to prevent separation of the container from the carrier. The hook mounting and operating mechanism illustrated in Figures 1 to 4 consists of a square shaft 13 journaled on brackets 14 secured to center sills 5 and a plurality of hooks 15 nonrotatably mounted upon shaft 13. The end of shaft 13 will be provided with a ratchet and pawl arrangement whereby an operator may rotate hook 15 into and out of foot engaging position.

ile a single downwardly pr0 ect1ng centrally located container leg and hook therefor will be suflicient to retain the container on the carrier and prevent any free play between them, it is preferred to provide two s aced central legs as shown and to mount hoo 16 on individual floating shafts 17. Rotation of hooks 16 is obtained by providing the adjacent faces of

hooks

15 and 16 with inter-meshing gear segments 18, whereby operation of the shaft 13 and hooks 15 will positively and simultaneously operate hooks 16 in the opposite direction to function the same way. If the hooks are made the same width as the pockets in feet 9, filling the latter when engaged therewith, the containers will be locked against longitudinal movement on the carrier, as well as against vertical movement.

It will be noted that when the carrier is held down by a single hook centrally located, it will be impossible for the carrier to tilt about any of its edges as a fulcrum.

In Figure 5, I have shown a container whose bottom wall 20 is provided with flan ed floor supports 21, the medially 10- ca one of which is preferably in the form of an I-beam to which are secured fish plates 22 having laterally extending wings 23 at their ends.

Parts

21, 22 and 23 can be made in the form of a single casting, if desired.

24 indicates the floor of the carrier, shown in this instance as a flat car. in which are preferably introduced metal thimbles 25 forming openings in which are located oscillating hook-shaped securing devices for the container having head portions 26 preferably of a size to fill the upper ends of the thimbles 25 and close the o enings through said thimble-the heads 26 eing flush with the floor of the carrier when in a retracted position, thus providin a solid fiat surface. It may be said that the fastening devices disappear when retracted. When said fastenm devices are projected upwardly into loc ing position, they will move continuously in one direction until they engage an appropriate keeper member on the container. 27 indicate the shanks of the fastening devices, preferably pivoted on shafts 28 and having inter-meshing gear teeth 29 when the fastening devices are employed in pairs.

It is obvious that but one fastening device may be used, but I have shown two of such devices which when projected move towards each other into locking position and engage the keeper between the wings 23 whereby the container is prevented from moving vertically or in any lateral direction. By intermeshing the hooks of a pair of fastenin devices, it is possible to operate the meshe pair from a single shaft. It

may thus be said that the companion fastening device is floating in that its position is determined by the shaft operated and driving member. \Vhcn the hooks re raised, they engage the wall of the thim le which constitutes a limit stop, and when the hooks are retracted and lie flush with the floor, the perpendicular face of the head portion engaging a wall of the thimhle also constitutes a limit stop and provides a solid support for the head of the hook so that said hook when retracted offers practically a solid floor support. The end of the head portion of the hook which engages the keeper of the container may be shaped or stepped in any appropriate manner, at the will of the designer.

The construction of the container disclosed herein adapts it for hauling material of various kinds, both loose and package. By the use of this system, delays and damage arising from frequent transfer of merchandise from one carrier to another are obviatcd. The container is designed to provide a maximum amount of strength for its weight and to resist collapsing tendencies when being transferred from one carrier to another. The keeper operating mechanism is sim )le and efficient.

Other modifications of the container and its assembly on the carrier besides those suggested herein may be made without departing from the spirit of my invention, and I contemplate such changes in the commercial development of my invention.

This present invention is a modification of applications, Serial No. 359,071. filed February 16, 1920, and Serial No. 430,902, filed December 15, 1920.
