I EDWARD FISHER BAMBER of St. Swithin's Lane in the City of London,
Civil Engineer do hereby declare the nature of this invention to be as follows:----
.
.
An open box or tray is so constructed that the back end, the bottom and sides
are when in use rigidly connected, whilst the front end is movable, either sliding or
hinging on to the rigid portion, whilst the box is being loaded the movable end
is secured or fastened, so as to be opened either by hand or automatically The top
of the movable end is attached by a chain or otherwise, to a ring, the back end
being attached to the same ring, so that the box is thus held firmly either
horizontally or in an inclined position; the front part of the box is hung
separately so that it can be lowered and raised or raised automatically. In this
position the box is closed and the material is loaded into it-By letting go the
chains or other arrangement, attached to the front of the box, while the movable
door and back remain stationary, this end is opened, the bottom forming an
inclined plane down which the material slides gently, instead of being suddenly
ejected as in the ordinary forms of tipping tub.
}
By another arrangement of chains and levers the front end of the box or tray is
lowered (the sliding door remaining nearly stationary) so far as the sliding door
allows it to travel, the bottom of the box or tray forming an ipclined plane as
already described.-Or by lowering the front end of the box or tray secured by
levers, catches or an arrangement of chains, levers or pulleys &c. and opening a
hinged door the box or tray falls as far as the hinged door, levers or chains are
arranged to allow it to. The box or tray is hoisted or lifted to its original
horizontal position or nearly horizontal position as may be required, either by
hand, with chains, levers, pulleys or counterbalances, or may return to its horizontal
or nearly horizontal position automatically by an arrangement of levers or counter-
balances When it has returned to this position the sliding or hinged door closes,
and is secured as already described. For weighing purposes the box is attached to
a steel yard, when after the weight is adjusted the material is discharged.

I, EDWARD FISHER BAMBER of 6 St. Swithin's Lane, London, Civil Engineer
do hereby declare the nature of my invention for FACILITATING THE HOISTING
WEIGHING AND DISCHARGING OF MATERIALS (being a communication from Sandford
James Kilby of Calcutta) and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The invention consists of a box or tray of suitable material closed in on the
bottom sides and back. The sides of the box at front are cut at an angle, but any
other form may be used; near the front edges of the two sides slots are cut, and
the front end of the box or tray is closed by a loose door, working inside it, having
parts projecting through or into the slots, which thus become guides for the door.
The box is suspended near the centre by rods or chains attached to a crosshead,
which has a hook or other means by which it is suspended in the centre from a
steelyard or hoisting gear. On the top of the sliding door a chain, rod, or rope is
fixed, which is attached at the other end to the centre of the cross-bar by a ring.
As thus described the box or tray is hung almost in the middle, while the
sliding door is attached to the cross head. When being loaded it is kept in a
horizontal position by one or more levers on the cross-head. The front end of the
box is attached by chains or other means to the small ends of the levers, and the
long ends of the levers are kept down by hooks or other attachments at the back
end of the box or tray.
When the box or tray is filled the long ends of the levers are detached which
allows the front end of the box to fall, the front portion being somewhat heavier
than the back, the sliding door being attached to cross-head and thus stationary,
the front end opens of itself and the contents are shot out.-A stop catch fastened
outside on the front end catches the suspending rods and prevents the box or tray
from tipping backwards.
When the machine is required to be used under conditions to prevent the proper
working of the levers above described, or when being used for hoisting materials
out of the holds of vessels, the levers are removed and two hinged clutches, which
are fastened to the sides of the box or tray close on the suspending rods; in this
way they hold the tray in a horizontal position and prevent it from tipping either
way; by lifting up the clutches the tray tips forward and discharges itself. By
pressing down the back end the front end is raised, and the sliding door by its
own weight slides down the groove and closes itself, the hinged clutches are closed
on the rods, and the tray is again fixed in the horizontal position. By weighting
the ends of the levers or the back ends of the box or tray it can be made to return
from the tilting to the horizontal position automatically.
For the better understanding of my invention a side and an end elevation of the
apparatus are attached in which A is the side of the box, B shows the angle at
which the front part of the sides are cut away, C is the slot of which there is one
on each side of the box, D is the sliding door, E the pins attached to the door

page_text: projecting through the slots C, which form guides for the sliding door and prevent
it from falling out, H are the suspending rods, J is the hook for suspending the
box to a steel yard or hoisting gear, K is the chain or other means for attaching
sliding door D to crosshead H, M is the stop catch which by projecting and
catching suspending rods F prevents the box or tray tilting backwards, N is the
hinged clutch which when closed on the suspending rods F F prevents the box
tilting either way, P are the levers, R. the chains or other means, of attaching
short end of levers to front end of box S are attachments at back end of box to
catch and hold the long ends of levers, U is a guide for the sliding door fixed on
the insides of the box, V is an iron ring for hoisting or lowering the machine, and
W a slide into which an automatic counter may be fixed.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, 1 declare that what
I claim is
1. The arrangement of parts as described, by which a box or tray can be easily
loaded and its contents weighed and rapidly discharged, while the box is easily and
quickly brought into position to be filled again.
2. The system of fixed door by which the box opens and closes itself when
tilted, by the opening of levers or clutches, and thus allows its contents to slide
easily down an inclined plane.
3. That the movements of lowering and raising the front end of the box or
tray enable a separate automatic counter to be attached by which the quantities
weighed may be automatically registered.
