TOTE BOX TILTER
ABSTRACT OF THE DISCLOSURE:
A bin positioning device has a wheeled chassis with a pivotally mounted platform for picking up a bin, transporting the bin, and selectively raising and tilting the bin to a predetermined angle by use of a motorized hydraulic ram, to facilitate access to the bin, to the limit where the contents of the bin are dumped. Bin retaining catches to stabilize the bin when tipped to an angle exceeding 90° may be provided, also a protective apron to safeguard the mechanism of the device from damage by bin contents when being dumped.

chassis includes a pair of spaced apart base members Eitting in one embodiment in close, overlying relation with tne support chassis and its wheels. In an alternative embodiment the base mem~ers of the auxiliary chassis lie between the wheeled members of the support chassis. A motor driven hydraulic pump connected in pressuriziny relation with the ram, which is generally o-f the slmple, single actiny piston and cylinder type, permits the upward pivotal displacement of the auxiliary chassis base members beneath a bin, to raise the feet of the bin clear of the ground.
; The positioning device can then be wheeled away, transporting the ra~sed bin and its loa~ to a desired locatlon. At such location, as for instance a machinists work station, further actuation of the moror and pump causes greater extension oE the ram, to raise the bln upwardly in tiltin~ re:Lation until a desired bin position is achieved to af~ord the required access by the machinist to the contents~of the bin, or to dump the contents.
In the event that the contents oE the bin require to be dumped, or so as to provicle greater unimpeded access to the interior of the bin, the ram may be extended to tilt the bin throuyh an angle in excess o~ 9~~

DE~CRIPTION OF T~IE PK~FERXED _M~ODIMENTS:
Referring to Figure 1, the bin positioning device 1~ has a support chassis 12 including a pair of base members 14, front 2Q wheels 16 extencliny forwardly of the members 14 in tixed relation therewith and a pair of rear wheels 18 pivotally mounted in castoring relation from support brackets 2~. A platform 22 carries a battery 24 to energize mo~or 26 in driving relation ~ wlth pump;2~. The control 3~ controls energization of motor 26.
: ~ A pair of mast portions 32 extend upwarclly from the support brackets J~O
An auxiliary chassis 4~ has base member means 42 ot invertecd channel section (Figure 3) and radius arm means 44 pivotally mounted at axis 46 by pivot pins 48 (See Figure 5~.

~ ydraulic fluid is admitted to or released from cylincler 54 ~y way of concluit 6~.
~ eferriny to ~`icJures 6 and 7, a pair of side plates 7(i and apron 72 are secured to the radius arm means 44.
lOBin restraint latches 74 are piv~ted at 76t each havin~
; counterweight 7~, positioning stop 8U and bin contact bar 82 mounted on radiu~ arm 8~1.
In the position shown in Figure 6 having the bin 9U in the "down" position, the counterwei(~ht 78 raises the bin contact bar 82 above and clear of the bin top e~ge, to permit free access of the bin 9~.
With the bin tippeci upwardly to a dumping condition, each counterwei~ht 78 rotates a bin contact ba3- 82 into constra1ning relation against the bin upper eage. The positioning stop 8~ determines the over-centre position of the contact bar ~2/ so that it cannot be displaced by the bin, and the bin 9U is positively latched.
In the raised position of the bin 9~, the apron 72 serves to deflect any articles sliding lrom -the bin, so as to fall clear of the battery and other functional components.
It will be understood that in place of battery 2~ an electrical extension cord can be utiliæed. Thus, at the loadinc~
zone, the bin 90 could be lifted by enercJizincJ the motor and :

While Fic3ures 1 and 3 disclose an embodiment wherein the auxiliary chassis 4~ has base mernbers 42 overlying the base members 14 o~ the device 1~, a further ernbodiment has the base members 14 thereo~ in widespread relation, having the auxiliary chassis base members 42 located therebetween. This further embodiment permits the device 1~ to straddle both sides oE a suitable load, while also permitting the auxiliary chassis base members 4~ to have a reduced ground clearance. This enables the entry cf base members 42 into more restricted pick-up spaces, as in the case c,f smaller tote-boxes.
; ~Referring to Figure 1, a handlebar 92 has arm portions 94 attachecd by plates 95 an~l pivots 96 in frictional engac3eme-nt with brackets 97. The upper and lowe extremities of the plates 95 serve to limit the extent to which the handlebar 92 can be raised or depressed. The frictional enc3agement of pivots 96, generally achieved by use of a bevelled washer, is sufficient to maintain the handlebar 92 in a selected position, to the extent of enabling the transmission of effective pulling, pushing and steerlng forces by a user to the device 1~.
