Address for Service: Complete specification for the invention entitled: TIPPING DEVICE The following statement is a full description of this invention, including the best method of performing it known to me 1

A

la TIPPING DEVICE This invention relates to a tipping device and more particularly to a tipping device to allow tipping of a bin pallet or other load supporting device adapted to be handled by the forks of a <fork-lift truck.

Many goods, loads and materials are handled by a fork-lift truck, either by being in a bin, or on a pallet or the like. Where material is carried by a •bin it is desirable to be able to tip the bin into another container or bulk transport vehicle or the like.

Thus it is an object of this invention to provide a device which is operable to allow tipping of a bin or pallet or the like supported on the forks of a fork-lift truck.

2 It is a further object of this invention to provide a tipping device for a bin or pallet or the like, in which the tipping is controlled by the operation of the fork-lift truck in an automatic or semi-automatic manner.

Thus there is provided according to the invention a tipping bin for use with a fork-lift truck said bin having fork receiving means pivotally connected to the base of said bin, the arrangement of said fork receiving means and the pivotal connection thereof to the base being such that, in a carrying position of the bin, the forks of the 4 'receiving means to underlie a forward region of said base to thereby prevent rotation of the bin relative to said fork receiving means, and, in a tipping position of the bin, the forks are partially withdrawn from said fork receiving means so that they do not extend beyond the pivot point of the receiving means to the bin, whereby the bin can pivot relative to said fork receiving means, and wherein said fork receiving means are elongate and extend, in the carrying position of the bin, so as to be at least adjacent to the rearward portion of 'the base.

The invention also provides a tipping bin ,for use with a fork-lift truck said bin having fork receiving means including elongate members mounted relative to the base of said bin such that they are capable of receiving respective forks of the fork-lift truck and of pivoting relative to the base about at least one axis transverse to the base of 3 the bin, the arrangement of said fork receiving means and the mounting thereof to the base being such that, in a carrying position of the bin, the forks of the fork-lift truck are received within respective elongate members and underlie a forward region of said base and rotation of the bin relative to said fork receiving means about said axis cannot occur, and, in a tipping position of the bin, the forks are moved relative to the base of the bin so that they do not extend forwardly of said axis, whereby the bin can pivot relative to said fork receiving means about said axis.

Prc.ferably, the bin has a front sidewall, rear sidewall and lateral sidewalls which extend upwardly from the base characterised in that the front sidewall is inclined forwardly relative to the forward edge of the base.

In order to more fully understand the invention description will now be made of a preferred form of the invention utilising a bin I adapteu to be carried and supported by the forks of a fork-lift truck.

t tf 'I In the drawings: FIGURE 1 shows the bin in the loading position; and r FIGURE 2 shows the bin in the tipping position.

In the preferred form of the invention bin 1 is provided with a base 2 having guides or slots therein for the reception of the forks of a r 4 fork-lift truck. The base 2 is divided into two portions, a forward portion 3 and a rear portion 4.

The forward portion 3 is situated on the bin on the forward side of the bin, that is remote from the fork-lift truck. Pivoted to this forward portion 3 there is a rear base portion 4 also having guides and slots for the reception of the forks, preferably the pivot being generally centrally of the bin. The forward portion 3 can comprise a pair of channel members 5 fixed to the base of the bin i.

The rear portion 4 comprises a pair of square tubular or partially closed members 6 braced by cross members 7 to form the base, and which is pivoted by transverse pivots 8 to the forward portion 3.

Thus it will be seen that when the forks 9 of the fork-lift truck are inserted and full distance into the members 5 that they pass through the rear portion 4 and through the membec 6 with the members 5 and 6 being aligned when the bin is resting on a surface, thus in effect locking the two portions together so that the pivoting cannot occur.

It will be realised thus that if the forks are then withdrawn to be engaged only in the rear portion 3, and that the forks do not extend past the pivot point, that on raising the forks that the bin will thus be raused to be tilted forwardly to discharge the contents of the bin. It will be seen from the drawing that the forward sidewall 20 of the bin is inclined forwardly. This facilitates discharge of the contents of the bin.

AL

0k In order to prevent the bin from inadvertently being removed from the forks of a fork-lift truck, a safety chain 14 is provided which is attached to the base portion 4 and to the fork-lift truck itself, this chain being adjusted so that the forks can only be withdrawn a distance to clear the pivot 8. As shown in the drawings the forks are withdrawn from the fully inserted position to the withdrawn position In order to limit the tipping and tilting, o a further chain or like flexible member (not shown) may be attached to the bin, and also to the mast of •i the fork-lift truck or other movable or controllable member so that this chain limits the tilting of the bin.

a oo .0 o This further chain also has the advantage s of allowing the automatic resetting or moving the bin back to its upright position.

0 0o It will be realised that the bin can be o: operated at a height so that the bin will tip into a container or the like or even a bulk transport o. vehicle, so that by elevating the bin, and resting the base portion of the bin on the edge of the container, withdrawing the forks until they pass the pivot point, that the bin if it does not automatically tilt and tip to its discharge position could be caused to do so by slight elevation of the forks themselves. With the bin then again resting on the edge of the container to prevent the bin moving forwardly, forward movement of the fork-lift truck will cause the forks to re-engage right r6 through into the base portion of the container whereby the container can then be lifted and then removed to its next position to be reloaded or the like.

Alternatively the bin can be returned to its erect position by lowering the fork-lifts to the ground where the bin will be returned by slight rearward movement of the fork-lifts to its upright condition, and forward movement will re-engage the forks in the member The upper edge of the bin includes a projecting flange or lip 22. This lip or flange stiffens the upper edge. The part 23 at the top of the forward sidewall 20 can be brought into engagement with the edge of the container to facilitate tilting of the bin.

Alternatively instead of the rear and forward portions being formed with rectangular tubular or channel members, a base can comprise a framework having vertical studs to form the fork J ,guides.
