OF NEW YORK, N. Y.

I swrvnnnn WHEEL non sorroa'rmc PORTABLE CONTAINERS.

Application filed December This invention relates to swiveled wheels for portable containers and the like, and is particularly adapted for'use on merchandise containers of large size, which are designed with a view to facilitating the transfer of freight in large units to or from a freight car, warehouse platform or delivery truck.

The general object of the invention is to provide wheels for this purpose of simple and rugged construction, improved means for mounting the same underneath the container,

and means for swinging the wheels to change their direction, so that the container may be moved in any direction desired.

The present invention makes it possible to move the container over the platform in any direction, and is especially useful'in transferring the container to and from box cars, since in that operation the container must be moved within the car in a direction at right angles to the direction of its movement in passing through the door of the car.

When used on box cars, the longest dimension of the container will usually extendapproximately from side to side of the car, and its width will be such that it may pass easily through the door of. the car, this being approximately half the size of the containers which are designed for use on fiat cars. Containers equipped with the present invention are also adapted to be handled on ramp tracks, or on any other loading and un loading or transferring device.

The preferred form of the invention and the principles of its operation will be more particularly described with reference to the accompanying drawings forming a. part hereof.

In the drawings:

Figure 2 is an end elevation thereof.

Figure 9 is a detail view, means for coupling two contamers together.

The merchandise container, in connect-ion with which my invention prises longitudinal sills 10 and transverse sills 11, in the form of I beams connected by corner castings 12. The side sills are also connected by girders 13, which sup ort the floor 14, and to which are secured t e walls 15 of the container. erably reinforced by ribs 16, and hinged doors 17 are provided atone end of the container, furnishing access to the interior thereof.

The corner castings 12 are formed with flanges 18 and 19 which are secured to the I beams 10and 1'1, and each casting is formed with a. cylindrical socket 20 adapted to rotatably receive the block 21, having ball bearings 22 on its upper face on which the is shown, comillustrating the These walls are pref casting is supported. The block 21 is repermit the removal of the block 21 when necessary.

The block 21 is formed with opposed downwardly extending ears 26 for receiving roller bearings 27, in which is supportedthe axle 28 of thewheel 29. A recess 30 is formed in the under face of the block 21 for receiving the upperpart of the wheel 29, and the bearings 27 are so located that the ends of the axle 28 are partially covered by the sides of the socket 20, thus preventmg endwise movement thereof.

The block 21 is formed with a peripheral worm gear 31, which is engaged. by a worm 32, splined on a shaft 33 extending longi tudinally of thecontainer, and journaled in the flange 19, and an ear 34 formed on the casting 12. Under certain conditions, as

hereinafter explained, the shaft 33 is moved longitudinally to a limited extent, while the worm 32 is held against longitudinal movement by the flange 19 and car 34.

As shown in Figure 3, two shafts 33 are provided for each container, and each shaft extends from end to end of the container, and is provided with two worms 32 which mesh with the worm gearson the respective blocks 21, carrying the wheels 29 at that side of the container. ratchet wheel secured to one end thereof,

and a lever 37 is provided which has at one end of the lever 37 being housed between the flanges of the I beam 11, as shown clearly in Figures 4 and 6. A pair of opposed dogs 39 are pivotally mounted between the arms of the yoke 38, and are adapted to be held in engagement with the teeth of the ratchet wheel 35 by means of a leaf spring 40 secured to the'yoke, and having curved seats 41 for receiving the ends of the dogs. VVhen the shaft 33 and lever 37 have been moved to the position shown in dotted lines in Figure 4, the dogs 29 are easily accessible, and either one may be man-- ually adjusted so that by rocking the lever 37 back and forth about the shaft 33 one of the dogs will rotate the shaft step by step in one direction, while the other dog remains inactive.

Each of the shafts 33 is surrounded by an expansile coiled spring 42, seated between one of the girders 13 and a collar 43 secured to the shaft, and this spring urges the shaft toward the dotted line position shown in Figure 4, but the shaft and lever 37 are normally held in'the full line position by a finger 44, which projects from a collar.45 secured to a small shaft 46 journaled in the web of the I beam 11, and which normally hangs downwardly over the lever 37, as shown in dotted lines in Figure 6. The small shaft 46 is held against longitudinal movement in the I beam by the collar 45 and a similar collar 47 secured to the stub shaft on the opposite side of the I beam. A cam 'arm 48 is formed on the collar 47 and projects laterally in parallel relation to the finger 44 for a purpose which will be presently explained.

The block 21 is formed with four equally spaced radial holes 49, two of which are are ranged in the plane of the wheel 29, the other two being arranged in the plane of the axle 28. A locking bar 50 is slidably mounted in a bearing 51, which is secured to the I beam 11, and in a hole 49 formed in the casting 12, and is adapted to be projected into one of the holes 49 to lock the wheel 29 in such a position that the container maybe moved either longitudinally or transversely. An expansile coiled spring 52 surrounds the bar 50 between the bearin 51 and a collar 53 secured to the bar, an

projects the bar toward the block 21, except when the baris positively held in retracted position by the engagement of the cam 48 Each shaft 33 has a.

with a finger 53, which projects laterally from the collar 53, as sh'own'in Figure 7 A collar 54 may be secured to the'end of the bar 50 to limit the extent of its projection.

Provision is also made for coupling the containers together when they are being transported on trucks or on flat cars, or when they are being moved over ramp tracks and the like. For this purpose, each side face of v the container is provided with a pivoted dog 55 and an eye 56, which cooperate respectively with an eye 57 and dog 58 mounted on the adjacent container, as shown in Figures 1 and 9. A rock shaft 59 is mounted on each side ofthe container, and is formed with a crank portion 60, which passes through a keeper 61 formed on an adjacent dog 55 or 58, as the case may be, and each end of the rock shaft is provided with an arm 62 by means of which it may be rocked to raise the dog, and release the eye which it engages. Each dog is provided with an engaging lip 63 having its outer face beveled, so as to automatically lock as the two containers are brought together. a

As above explained, the wheels 29 are nor- SIU mally held either in a longitudinal or transverse plane, and the locking bar 50 engages in one of the holes 49. The shaft 33 is held in-its innerposition, as shown in full lines in Figure 4, and the lever 37 is contained between the flanges of the I beam 11, and retained, in opposition to the pressure of the spring 42, by the finger 44, which normally hangs by gravity in the position shown in dotted lines in Figure 6. When it is desired to shift the wheels 29 so as to move the container in another direction, the finger 44 ,is swung upwardly, releasing the lever 37 and permitting the spring 42 to force the shaft 33 outwardly, bringing the lever 37 to the position shown in dotted lines in Figure 4, and at the same time engaging the cam 48 with the finger 53, retracting the locking bar 50,-and leaving the block 21 free to be rotated by means of the worm 32. One of the dogs 39 is then set so as to engage the teeth of the ratchet wheel 35, while the other dog 39 is left free. The lever 37 may then be manipulated to rotate the shaft 33 and worm 32 to turn the wheels 29 in any direction desired. As soon as the block 21 commences to turn, the finger 44 may be lowered, leaving the lever 37 in its outer position, and as soon as the block 21 and wheel 29 have been turned through an angle of they are again locked automatically by the projection of the lockingbar 50. The finger 44 may then be momentarily raised, while the shaft 33 and lever 37 are restored to the position shown in full lines in Figure 4. The wheels 29 will now be in position to move'the container in a direction at right angles to its side of the container.
