Improved Means for Facilitating the Hoisting, Weighing, and Dis-
charging of Salt, Coal, Metals, Grain, or any other Material.
I EDWARD FISHER BAMBER of 22 Addison Road North in the County of Middlesex
Civil Engineer do hereby declare the nature of this invention to be as follows:
--
It comprises improvements on iny invention the final specification of which was
filed on the 28th October 1886, and numbered 3081; by means of these improve-
ments the case rapidity and economy of working are increased.
In my former specification, a vessel is described closed in on the bottom sides and
back, suspended near the centre, with a sliding door so arranged that on moving
certain clutches the box tray or bucket moved away from it, and the contents
were discharged.
In my present invention a box tray bucket or other vessel is suspended near the
centre on trunnions, pintles or gudgeons by rods attached to a crosshead, or in a
frame, or is supported below by a cantilever. The front end of the vessel is closed by
a door fitting either its inner sides or against the outer faces of the sides and bottom.
The door can be connected either with the cross head or with the rods which suspend
the vessel by a bar or bars or other suitable means of attachment, which may be
fitted on to the crosshead or suspending rods so as to be capable of motion as the
door opens or they may be rigidly fixed. When the bars or attachments are capable
of motion, the opening of the door is arranged by means of connecting pieces attached
to the vessel and the door, or to the bars or attachments connecting the door with
the crosshead or suspending rods. On the front end of the vessel being lowered, the
back end raises the connecting pieces, and the door opens much wider than the
distance through which the front end of the vessel travels when tipped. When the
bars or attachments are rigidly fixed the size of opening will depend upon the angle
of tip, and is arranged by means of suitable cluiches. Moveable stops are employed
to regulate the extent of the forward and prevent backward_tip,, the latter being also
effected by the closing of the door against the bottom. Whilst being loaded the
vessel is kept in the horizontal or other determined position, and the door closed by
clutches or other suitable arrangement, the moving of which allows the door to open
and the contents to be shot out. The vessel returns to the horizontal position and
the door is also closed automatically by the weight of the door being thrown by
means of the connecting pieces on the back end of the vessel, thus causing the front
end to close up by means of catches against the bottom of the door.

COMPLETE SPECIFICATION.
Improved Means for Facilitating the Hoisting, Weighing, and Dis-
charging of Salt, Coal, Metals, Grain, or any other Material.
EDWARD FISHER BAMBER of 22 Addison Road North Notting Hill in the County
of Middlesex Civil Engineer (being a communication from Sandford James Kilby
of Calcutta) do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
It comprises improvements in my invention No. 3081 the final specification of

page_text: which was filed on the 28th October 1886; by means of these improvements the
ease, rapidity and economy of working are increased.
In my former specification a vessel is described closed in on the bottom sides and
back suspended near the centre, with a sliding door so arranged that on moving
certain catches the box, tray or bucket moved away from it, and the contents were
discharged.
The present invention has for its object the arrangement of the door of the box
tray or hacket described in my former specification in such a way that a wider
opening may be obtained and its contents may be more easily rapidly and economi-
cally weighed and discharged while the box tray or bucket is more easily brought into
position to bo filled again. For the better understanding of my invention drawings
(Figures I, II, II and IV) are annexed. These drawings show four varieties of
the box tray or bucket in which my invention is adopted and the letters indicate the
corresponding parts in all four drawings. The box iray or bucket is suspended near
the centre on trunnions pintles or gudgeons G by rods I attached to a crosshead A as
in figs. I & II, or in a frame as A A in fig. 4 or is supported from below in the
manner shewn as IU in fig. III. Instead of the sliding door described in my former
invention adopt the following arrangement.
The front end of the box tray or bucket is closed by a door C made to fit correctly
either on the inner sides of the box tray or bucket (see figs. I & IV) or against the
outer faces or edges of the sides and bottom (see figs. II & III) which sides and
bottom may have such additional closed ledges rims or projections to ensure the
door keeping closed as may be found convenient as in figs. I & IV. The door
can be connected either with the crosshead or with the rods which suspend the
box tray or bucket by one or more bars or other suitable means of attachment B.
The upper ends of the bars or attachments may be fitted on to the crosshead A
or suspending rods I or the connection V, so as to be capable of movement as the
door opens or they may be rigidly fixed. When the bars or attachments are capable
of movement (see figs. II, III, & IV) if a wide opening is desired a lever D
(or levers) motion bar (or bars) or connecting rod (or rods) is or are attached
to the side (or sides) of the box tray or bucket at W the other end X or ends
being attached either to the door itself or to a bar fitted on to the door or to the
bars or attachments connecting the door with the crosshend or suspending rods
(see fig. 1V). On the front end of the box tray or bucket being lowered the back
end raises tho lever motion bar or connecting rod and the door is opened wide.
The opening can thus be made much larger than the distance which the front end
of the box tray or bucket has travelled downwards while tipped. When the bars or
attachments are rigidly fixed (see fig. 1) the opening will be large or small
according to the angle at which the box tray or bucket is allowed to tip or fall
downwards from: the door. If at one time a large opening and at another time a
smtill opening is required the door may be made either movable or fixed at will
by means of clutches suitably arranged.
The box tray or Bucket tips as far as it is allowed to by the stops O placed on
the back end of the sides which intercept the suspending rods I in figs. I and II and I U
infig: II.
The position of these stops can be altered and the most suitable angle
for discharge can be thus secured.
While being loaded the box tray or bucket is kept in a horizontal position with
the door closed by one or more clutches or latches or some other suitable arrange-
ment either fixed on the sides of the box tray or bucket and catching the suspending
rods as at N in fig. I or fixed on the crosshead and falling into suitable grooves or
catches inade in or attached to the edges of the sides of the box tray or bucket as at N
in fig. I or fixed on to A or I and working as shown in figs. IV and III.
As soon as the box tray or bucket is filled the clutches or latches keeping, it in
a horizontil position are raised, when the front end being somewhat heavier than the
back end falls downward of itself while the door opens upwards as shown in
figs: IIIII, and IV or therbox, tray or bucket, falls away from the door as shewn in
fig. I and the contents are shot out.

page_text: A stop catch E fastened outside on the front end (see figs. I and IV) catches the
suspending rods and prevents the box tray or bucket from tipping backwards. In
the arrangements shewn in figs. I and IV this is also prevented by the door itself
closing down against the bottom. A small wheel or roller S fig. I can also be
placed on the bar which is fixed across the front opening so as to prevent any
outward motion of the door and also to act as a guide. In the arrangement shewn
in figs. II, III and IV the weight of the door when opened being thrown by the
lever motion bar or connecting rod on the back end of the box tray or bucket
The
at W the back end falls downwards as soon as the contents are shot out.
front end in coming upwards meets the door the clutches or catches N are closed
and thus the opening is kept securely shut until the box tray or bucket is again
refilled and ready to empty. By this arrangement (figs. II, II and IV) the box
tray or bucket returns to the horizontal position and the door is closed automatically.
To close any crevice or space between the edges of the door and the sides or
bottom of the box tray or bucket as well as to stiffen and strengthen the front end a
raised rim or projecting edge F figs. I and IV can be fixed on the inside of the
sides and bottom of the box tray or bucket such projection being bevelled towards
the inside and thus offering no obstruction to the free discharge of the contents when
the box tray or bucket is tilted.
The arrangement of the door above described adds greatly to the ease and
rapidity of the work of hoisting weighing and discharging salt coal metals grain or
other articles. The opening of the box tray or bucket being larger it is of greater
utility in the case of bulky articles such as rock salt or coal.
The work can also be carried on more economically than by my former invention
as fewer men are required to open the clutches or latches in order to cause the box
tray or bucket to tip and to return again to the horizontal position.
The door being arranged to open clear of the box tray or bucket there are
greater facilities both for discharging its entire contents and also of cleaning the
interior when required.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what I
claim is :
The improved methods in the construction and arrangement of the door of the
box tray or bucket described in the above named specification No. 3081 of 1886,
which are effected substantially in the manner hereinbefore described.
