(01."280-3) i e l The Vdriving sprockets I 1, I8 for these 4traction This invention relates to shipping containers of the kind used by railroads Vin the transporta- .tion of freight in less than carload lots. Suchv containers are ordinarily `proportioned and der signed for close arrangement in serial orderon flat freight cars, and adapted to be transferred sidewise from the cars to Station platforms orto motor trucks, trailers, etc., and-vice versa.

The chief aim of our invention is, to make possible the transfer 4of shipping ,containers ofthe kind referred .to without necessitating the aid of powerhoisting devices or lifting cranes,r(which are not always available, particularly at wayside railway stations), throughindividual incorporai tion with the containers,of"manuallyeoperable propelling mechanism toeffect either straightaway or curvilinear progression of thecontainers.

Our inventionis moreover directed toward securing the above desideratum in a manuallyoperative propelling` mechanism which is compact and' so organized and :allocated that it does -not interfere with thev usual close arrangementof the containers on the railway cars -or trucks,

AY,Still Vother objects and attendant advantages of this invention will be `manifest from the detailed description which follows of the drawings, wherein Fig. I is a side elevation of a shipping container conveniently embodying our invention in Aone form.

The shippingY container delineated inA Figs. rI-VI is, generally speaking, of standard constructiomthe same` havingsolidlend walls I I, and ,side walls i2 with doors I3 by which access is had Yto the interior. In accordance Vwith our invention welmountthe container ona chassis I4 which comprises two laterally-spaced fendless sprocket chain traction belts I5, I5 that'V extend Llengthwise of the oppositeendsof thercontainer.

the propelling mechanism of `the belts are respectively secured to aligned sections I9, .20 of a split shaft, having journal support in suitable .bearings 2|, 22 aiforded by the chassis. Fast on the contgu-ousinner ends of the shaft sections I9, 20 are opposing bevel gear wheels 23, 24 respectively. At right angles to `the split sprocket shaft and .extendingfrom one side I2 to the other of the container belovT the floor `25 of the latter is an actuating shaft 26`whereofthe 10 polygonal ends l21, zsproject somewhat beyond said container'sidesIZ. The shaft 2,6 is free within a split ,sleeve composed of twosections 29, 30 having'journal support in bearings 3I, 32 and 33 of the chassis I4. As'shovvn, the sleeve sections 29, 3U respectively terminate in squared ends 34, 35-sovmewhat inward of the polygonal ends 21, 28 of the shaft 26 which latter carries` a bevel pinion 36 that meshes with the bevel gear wheel 24 on the sprocket shaft section 20. Afjxed to the inner end of the sleeve section 25J-lare a bevel pinion `3`I which meshes with the bevel gear wheel 23 onltheother sprocket shaft section I9 and a spur pinion 38 which meshes with a mating pinion `39`on one end of another cross shaft 4I) which is journalled in the bearings 3I, 32 at a level Vabove the shaft 26. At its opposite end, the shaft 40 carries a spur pinion' 4I like the pinion 39, which .meshes with a companion spur pinion 42 on the inner end of thesleeve section 30. Y

'At143 is shown an actuating handle, which, within'a bifurcation at its lower end, carries, with capacity for Aindependent rotation, a pair of ratchetV wheels 44 and 45 respectively having axial polygonal openings to t the polygonal [ends .21, 28 and 34, (-115` respectively of the actuating shaft 26 and the sleeve sections 29, 3B. A pair of vdoubled-ended reversing pawls 46,41 for cooperating respectively with the ratchet wheels l,44, 45,,areindependentlypivoted on a .pin 48 which extends crosswise of the bifurcation of the handle 43 ,abovesaid ratchet wheels. Influential upon the pawls46, 41 are arcuate bale-like springs 4,9, U50, respectively, each `having three notches for lselective engagement withixed studs 5I, 52 on l the handle 43. o

i To manipulate the container, `the actuating Vhandle 43V is applied for example to the corresponding `polygonal ends of theshaft 25 andthe sleeve section 29 at one side of the container `as shown in Figs. I, I-IIand VL 'I"hepawls 46, `4'! lare next set by adjustment ofthe bale springs 49, SI1inaccordance `with the directionin which the `container is to bervprogressed. For straight-away ,progressienpf fthe-container inthe direction in Cil tion through motion imparted to them by theV intermeshing bevel gear couples 24, 35 and 23, 3l. By setting the pawls 455, 4l so that their left hand ends simultaneously engage the ratchet wheels 44, 45, and thereupon swinging the han- Y dle 43 as before, the` container will obviously be progressed straight-away in the direction opposite to that shown by the arrows in Figs. II and III. Again, with the pawl 45 in neutral as in Fig. VI and the right hand end of the pawl 41 in action, only the sleeve section 29 will be turned anti-clockwise. through,cooperation of the bevel gear 23 and pinion 3l with consequent impartation upon swinging of the handle 43, of movement tothe traction belt l5 alone, the container being thereby caused to turn leftward while the traction belt l@ remains idle. Similarly, with the pawl 4l in neutral and the left hand end of the pawl 46 inaction in Fig. VI, the container will be turned'rightward incident to progression in the direction of the arrow in Fig. III upon actuation of the handle '43, .To operate the traction belt i6 alone, the pawl 4l is placed in neutral and either the right hand or left hand end of the pawl 45 placed in action, whereby, upon swinging the handle, the container is correspondingly steered either to the right Aor left incident to its progression with the traction belt` I5 idle. By applying the handle to the corresponding ends of the transverse shaft and sleeve at the opposite sides ofthe container, and'proceeding as above explained, the container may be progressed either forwards or backwards or along curvilinear paths Veither. leftward or rightward in identically the same manner as before, the movements of the sleeve section 3S being communicated to the sleeve section through the spur gear couples 4l, 42 and 38, 39 and the cross'shaft 40. Thus, through our invention, it is possible for one man aloneto manipulate the container as desired or required to move it onto or off a railway car, station platform or'truck, the operation being com- Vparativelyreasy by virtue of the-reducing differential ratio of the bevel gear couples 23, 31V and .24, 36'. While the actuating shaft 26 mayif desired, be otherwise located, `we prefer to place it near one end ofthe container so that during the actuation of the handle, the operator can see around the corresponding corners of the container and better direct its progress. c

The modified formfof our invention shown in Fig. VII is like that of Figs. I-VI but capable of operation from one side only of the container.y ,In this case, the actuating shaft 26a is comparatively short with only one of its ends 27a polygonally configured and projecting beyond a door side 82a ofthe container. As before, the shaft 26a `carries a bevel pinion 36a that meshes with a bevel gearwheel 24a on the sprocket shaft section 2M. Moreover in this case, but one sleeve 29a is employed, the same having its ends squared as at 34a, carrying a bevel pinion 31a which meshes with a bevel gear wheel 23a on the sprocket shaft section 19a' 'for the traction belt ld, the sleeve section 3l), the spur pinions 38, 39, 4I and v42 andthe'shaft 40" of the rst described embodiment being entirely dispensed with here. All other identical features` not specifically referred to in the modification are identified with the same reference numerals used in Figs. I-VI with the addition, in each instance, of the distinguishing character afi The operation of the modified form of our invention is obviously identical with that of the rst described embodiment. By reason of the allocation of the connections for attachment of the actuating handle 43 in both cases at the door sides l2 of the containers, the closed ends Il of the latter are left free of any projections which might tend to interfere with the desired close arrangement of the containers on the railway cars or motor trucks.
