Improvements in or connected with Means or Apparatus for the
Removal and Discharging of Ashes and other Matters from the
Holds of Navigable Vessels.
1, JAMES BROWN, of 11, Seacome Street, Liverpool, in the County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
According to this invention the ashes to be discharged from the stoke-holds of
ships are elevated therefrom in buckets or tubs having a tumbling bottom, or
buckets of the kecking or reversing type, such buckets being elevated from the
stoke-hold to the deck through a ventilating, or special, tube or shaft. The bucket
is filled in the usual way in the stoke-hold and then brought under the elevator and
hoisted up.
When at the point where it is to be discharged, the bottom is caused
to open, or the bucket is kecked or reversed, as the case may be, and the contents
shot into and passed down a shoot, such shoot either leading to the side of the ship,
or to a gang-way, or other suitable spot.
The emptying of the buckets may be effected by hand or by automatic means.
When the discharging is effected automatically, a suitable tumbling and kecking
arrangement is provided in connection with the tub and the tube or shaft through
which it is elevated, whereby, when the tub arrives at the top of its travel, the
actution of the mechanism is effected, the bottom of the tub is released, or the tub
kecked or tumbled, and the contents discharged therefrom.
In the case of a tub having a tumbling bottom, when the bottom is released, it
falls down about its hinge and it makes in conjunction with the shoot before
specified, a continuous way, down which the ashes or other matters can pass
overboard, or to other point of delivery.
The aperture in the tube or shaft, through which the contents of the bucket are
discharged, may be adapted to be closed when not being used; and when a special
door is not used for this purpose the shoot or a part thereof may be adapted to
move and serve as a door or be used for the purpose. This discharge aperture is
in all cases where convenient, provided athwartships, so that a direct discharge of
material to the gang-way or overboard is afforded.
For the purpose of diminishing the effect of the tubs or buckets coming into
contact and rubbing against the surface of the tube or shaft, up which they are
moved, I provide on the tubs or buckets wood or other suitable material in such a
manner as to form a buffer, or a yielding surface. Or, the bucket or tub may be
guided within the shaft or tube in such a manner as to prevent it rubbing against
the surface thereof. In the latter case the guiding means should be so arranged
that the tub enters the tube or shaft without nice adjustment, that is, with ease;
and the tubs may be provided, if desired, with wheels by which they may be
moved about the stoke-holds more easily.
It is to be understood that this invention may be applied to different purposes,
and it may be carried out in connection with the existing means for raising and
lowering tubs or buckets or the like; or, it may be carried out by means of
elevating mechanism and shafts or tubes specially provided, and for the purposes
of this invention. It is also to be understood that in carrying out the invention
different forms of tubs or buckets may be used.

page_text: Improvements in or connected with Means, or Apparatus for the
Removal and Discharging of Ashes and other Matters from the
Holds of Navigable Vessels!
I, JAMES BROWN, of 11, Seacome Street, Liverpool, in the County of
Lancaster, Engineer, 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 :-
According to this invention, the matters, such as coal, ashes, and other substances,
to be discharged from the holds of vessels, are elevated therefrom in buckets or
tubs having a tumbling bottom, or buckets of the kecking or reversing type, such
buckets being elevated from the hold to the deck or other part. The bucket is
filled in the usual way in the hold and then hoisted up by the elevator. When at
the point where it is to be discharged the bottom is caused to open, or the bucket
is kecked or reversed, as the case may be, and the contents shot into and passed
down a shoot, such shoot either leading to or through the side of the ship, or to a
gang-way, or other suitable spot.
The emptying of the buckets may be effected by hand or by automatic means.
When the discharging is effected automatically, a suitable tumbling and kecking
arrangement is provided in connection with the tub and the way or tube on or
through which it is elevated, whereby, when the tub arrives at the top of its
travel, the actuation of the mechanism is effected, and the tumbling part of the tub
is released, or the tub kecked or tumbled, and the contents discharged therefrom.
In the case of a tub having a tumbling bottom or part, when the bottom or part
is released, it falls down about its hinge and it makes, in conjunction with the
shoot before specified, a continuous way, down which the ashes can pass overboard,
or other matter such as coal, passed to its point of delivery.
In the case of the application to discharging ashes, the aperture in the tube
through which the contents of the bucket are discharged, may be adapted to be
closed when not being used, and when a special door is not used for this purpose
the shoot or a part thereof may be adapted to move and serve as a door or be used
for the purpose.
This discharge aperture is in all cases where convenient,
provided athwartships, so that a direct discharge of material to the gang-way or
overboard is afforded. In this case also for the purpose of diminishing the effect
of the tubs or buckets coming into contact and rubbing against the surface of the
tube, up which they are moved, I provide on the tube or buckets wood or other
suitable material in such a manner as to form a buffer, or a yielding surface. Or,
the bucket or tub may be guided within the shaft or tube in such a manner as to
prevent it rubbing against the surface thereof. In the latter case the guiding
means should be so arranged that the tub enters the tube or shaft without nice
adjustment, that is, with ease, and the tubs may be provided, if desired, with
wheels by which they may be moved about the stokeholds more easily.
It is to be understood that this invention may be applied to different purposes,
and it may be carried out in connection with the existing means for raising and
lowering tubs or buckets or the like; or, it may be carried out by means of
elevating mechanism and means specially provided, and for the purposes of this
invention. It is also to be understood that in carrying out the invention different
forms of tubs or buckets may be used.
In the drawings which serve to illustrate this invention, I shew two applications
or forms of apparatus. One, that shewn in Figures 1 and 2, being for discharging
ashes, and that shewn in Figures 3 to 7 being for discharging coal from a vessel
into a ship, that however shewn in Figures 1 and 2 may be used also to discharge
coal from one vessel to another.

page_text: Figure 1 is a side view of the apparatus, shewing the ship in cross section; and
Figure 2 is a sectional plan of the tube-shewing also the bucket - taken at the
line XX Figure 1.
Figure 3 is a sectional view shewing my improvements applied to discharging
coal (or other material) from one vessel (say a float or lighter) to a ship.
Figures 4, 5, 6 and 7 are details of parts of the apparatus shewn in Figure 3.
Like or equivalent parts are marked with the same letters and figures of reference
wherever they occur in the drawings.
With reference to the drawings, the tub or bucket is designated a, and the tube
or other guide in or on which it runs is b. c denotes the tumbling door of the
bucket or tub; d is the shoot or hopper into which the contents of the tub or
bucket are shot.
Referring now more particularly to Figures 1 and 2, the tube may be taken to
represent one of the ordinary ventilating tubes of a ship, say of the stoke hold.
This tube is provided with an aperture at e through which the contents of the
tub a pass, its lower end being open in the ordinary way. The tub is hauled up and
lowered by a hand or power winch by the rope f, which passes over the guide
pulleys
The tumbling door c of the bucket or tub is hinged at c', and the opening in the
tub is partly at the bottom and partly at the sides and the front and is represented
in the figures by the line a. The bottom part of the tub may be inclined, to
render self emptying certain, as shewn by the dotted line a². The door c as shewn,
covers the aperture of the tub at the side thoroughly and forms part of the bottom
of the tub, and it is locked and unlocked by the snack c*. But any other fastening
and releasing device may be used and may be of the non automatic, or of automatic
kind adapted to be released by coming in contact with a projection or equivalent
provision on or in connection with the tube b.
The contents of the tubs are led by the shoot d into a tube g when it is desired
to discharge them overboard. This tube is, in the example shewn, fastened
to the deck and skin i of the ship. A door g¹ is provided to close the
mouth of the tube g when it is not being used for the purpose of discharging
ashes overboard.
The aperture of the tube bat e is also closed by a door, if desired, when not
being used as a guide to the tubs a.
In operation, when a tub or bucket a is full, it is elevated up the tube b until it
takes the position shewn in dotted lines opposite the aperture e, when the snack c
is removed, and the door falls forward into the position shewn, and the contents
are shot out into the shoot d. From here, of course, they pass by the tube
overboard. When the tub a is empty, it may be lowered without shutting its
tumbling door by hand, as in its descent the tube b causes the door to shut and the
snack may then be moved to catch it.
The tube is shewn provided with a wood or other guiding stop j, by which
the tub is steadied in its ascent and descent. Like strips may be placed in other
parts of the tube to further steady the tub. Or, these strips may be provided on
the tub a itself.
In the application of my invention shewn in Figures 3 to 7, coal or other
material from one vessel is discharged into another. In Figure 3, 1 represents the
vessel from which the coal, or other material, is being discharged, and 2 is the
vessel into which it is being charged from the tubs a. The tubs a in this example
run on a guide frame b, in lieu of in one as in Figures 1 and 2.
The tumbling door, in this example, is not locked, but is kept closed normally by
a bar or bars (forming, as it were, a continuous "snack") c³; but this snack bar
ceases at a point just above the mouth of the hopper or shoot d, and as soon as the
door c is past the bar c', when being hauled up, the door tumbles or falls open and
the coal or other material is shot out into the shoot or hopper d. In the return of
the tub, the door e is automatically shut in the same manner as set forth with
reference to Figures 1 and 2, and is kept shut by the "snack” bar c³.

page_text: The bars in Figure 7 are connected to cross bars b', which are removed at the
part of the frame b where it is desired the tub door c should tumble; whilst in
Figures 4, 5 and 6, the said bars c* are of telescopic construction, the upper end of
the top one being fastened to whichever of the cross bars it is desired it should be.
In changing its attachment from one cross bar to another, the said upper bar c
telescopes into the other. The tub is guided by the straps thereon which fit over
the edges of the guide frame 6 as shewn.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, what I claim in respect
of the herein described invention is :--
°
1. The herein described improvements connected with the discharging of sub-
stances such as herein specified or referred to, from navigable vessels, consisting of
a bucket adapted to be filled with the material to be discharged and to empty as
described, and working, that is raised and elevated, in connection with a guide or
guides; substantially as herein set forth.
2. The herein described improved apparatus for discharging substances, such
as herein specified or referred to, comprising a bucket a and guide frame b
arranged and adapted to operate substantially as set forth with reference to the
drawings.
3. The herein described construction of bucket or tub for the purposes specified,
consisting of a body a, a tumbling door e hinged at c', arranged and operating as
set forth with reference to the drawings.
