As is heretofor indicated,the truck will frequently operate upon an elevated cat-walk below which thestorase bins aredisposed. Where 'the cargo is; ore or coal,'- :it might contai n hard;

lumps which will find their way to thecat-walk." The truck during the course of its travel might be;

However, if the steering mechanism wereof-the self-locking type so that it vwere' non-responsive to jolts of the steered wheels, then the possibility j of accidentally running off of thecat-walk would bemateriallyreduced.

The steering mechanism is arranged to have} 1 a such, a self-locking means andis controlled by a steering wheel '30 which is preferably horizontally disposed'in-'advance*of the control panel 24 as is more clearly seeninFig. 1. Suitably connected to the steering wheelas "by meansof-a key 32 and nut 33 is""a si'lbsha'ftlM' which-is journalled in a block 36. -This bloclc is seen'in detail in Fig. 12 and comprises a bod-y' portion from which projects'afpair'of pivot arms 38.

Thus the shaftifl 'i'sirais'ed or lowered withrespect, to the block 6 or"frame l 5' and bymeans'of 'thebell crank pushes orpulls thesteering reach and ni-anipulates ltheindividual frontaxles. .It will also 'beseenfthat jar's im parted to "the steeringknucklesby' meansjof the V front wheelsicoming in contactw'ith lumps of the character de'sc'ribedfwill notfbe transmitted as rotational energy to the steering wheel and cause the truck to swerve off thecat-wallr.

ters of the steering column. The instant center of the steering column with respect to the frame I5 is stationary and is the axis of the pivot arms 38. .'I'he instant center of the steering column .with respect to the bell crank.55 is at 51. Thus when the steering wheel 30 is actuated, the whole steering column simultaneously pivots about the thereof and will now be described in detail. Thecoupling as distinguished from the power means for driving the same; will be described first, reference bein'g'had particularly to' Figs. band 6. The coupling is in the nature of a wrench which is the driven member'of a universal joint; .The driving member of the universal joint is a square bar 15 which is provided with an enlarged boredend 16. The driven member,.indicatedgenerally by 18, is provided at one end thereof with an axial bore 19 and at theotherendthereof with:a square recess which intersectsjthe bore 19. The square recess80 maybe hexor any other configuration so'tas'to permit it to be coupled toztherailroad carbottom gate actuating shaft. j

" 'For interconnecting the driving and the driven membersthere is projecting intothebore i9 and the bore of the-end'lt an elementBZiwhich, it is to be noted, is of circular transverse:crosssection and .presents av pair of high spots, .one disposed within each of the bores andone'of which isindicated at 83. These high spotsmay, in longitudinal crossrsection, be V or u shape. Thus the element 82 in longitudinalcross section is-in effect substantially aw As is seen in Fig. -6,' the element 82'has extending ,therethrol gh a pin 84 the ends of which occupy circumferential extendingslots' 85 of the end .16. ,A similar pin 84a and slot 85a interconnect the element;82 andthe driven element .'l 8. Pin 84 isdisposed at right anglesto pin 84a. and for permittingplay, the

slots are longer than the transversedimensions of the pins." Hence, the" driven; element 18 may Thus the driven element [8 and the square shaft 15 are interconnected for the transmission of rotational energy even; though they; are swung out of alignment. This universal joint, permitting as is above noted, alimited amount of rotationalplay between and non-alignment of thedriven element It and the square bar 15', is useful in coupling the driven element I8 to the gate actuating shaft and eliminates undesirable inching of the truck for aligning the recess 80 with the gate actuating shaft; g Q For purposes of preventing injury to theflng'ers of the operator, a suitable,,flexible jacket 81 madepof rubber for instance, is provided and covers the entire universal joint. 1 As is above said, the coupling is power driven. The power drive',;however,- not only rotatesthe coupling but also raises and 'lowers'the same-and axis of the-sprocket wheel I. Rotatably jour-' n'aledat one endto the shaft [Stand at the other endto the shaftllil are a pair, of spacerarms 112.. Shaft l'lllis provided at, oneend with a flangejl 13 and at the other end with a washer and nut If" for maintaining in assembled relation the various elements which are supported thereby. It is'thus seen that'as the'driving shaft IBILrotates, the brackets ll 3,;the spacer armsl 35 and H2 all pivot relatively to each other: It, will also be seen that regardless o f;the-elevation of the square bar I5, the same maybe rotated,

By inanipulationof the steering wheel 30 the truck is steered so that the coupling element isv in the,

immediate vicinity of the end of the gate actuatingjshaft. The switch I82 is utilized for raising or lowering the couplingto the same level as the gate actuating shaft. The operator while standing on the platform reaches over thepl'ate 22, grabs the jacketlfl and manuall longitudinally moves the square bar until by means of the play hereinbefore described the-driven element 18 of the coupling is coupled to thegate actuating shaft. Then by manipulation of the switch lever IBI the motor 94 rotates the square shaft and consequently the gate actuating shaft in' one'direction or another for opening or closing such gates.

After the gates areopened or closed the'coupling is disconnected and the truck propelled to' the next car.

The rounding of the corners and generalistreamlining render the device less likely to'engage obstructions so that the same may be operated in relatively close quarters, H I
