PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Discharging Ashes from
Steamboats.
I, JAMES JACK GALLOWAY, of 43, Mair Street, Plantation, Glasgow, in the
County of Lanark, North Britain, Engineer, do hereby declare the nature of this
invention to be as follows, that is to say :-
My said invention relates to apparatus to a considerable extent of the kind
described in Patent Specification No. 4033 of 1880; and has for its object to
improve various details and arrangements of or connected with such apparatus.
In carrying out the present invention the motor used may be similar to that
described in the said earlier Specification, or any suitable known and simple kind
of hoisting engine may be employed, its speed being regulated by means of a
cylinder containing oil or other liquid, or being controlled by valve gear of the
kind employed in steering and starting and reversing engines. The motor may be
arranged to work a pump to supply water for a purpose hereinafter explained. In
some cases in which the height of the lift is not great the gearing may be worked
by hand.
As formerly the lifting gearing is arranged to raise the ashes bucket within a
tube or trunk (which will in many cases be that for leading air down into the stoke
hold) to a sufficient height to prevent water reaching the top of it through the
discharge tube, but instead of sloping the discharge tube from the highest point
to the side of the ship, the first part of the discharge tube is directed downwards
to and through the deck, and continued under the deck to the side with little or no
slope. The discharge tube when thus arranged is more convenient and more out
of the way of other things. The tipping of the ashes bucket may be effected in
the manner described in the earlier Specification hereinbefore referred to, and any
of the appliances described in that Specification may be used for moving the ashes
along the discharge tube. It is, however, by the present invention proposed to
employ one or more jets of water suitably applied in the discharge tube for moving
the ashes along that tube, such water being supplied by pumps hereinbefore
referred to, or by any available pumps on board the vessel.
When the ventilator tube or other tube through which the ashes bucket has to
be hoisted has its bottom end at some height above the bottom of the stoke hold, a
movable guide cage is by this invention fitted to the lower end of it, to guide the
bucket up into the tube and to prevent it from swinging about with motion of the
vessel. This guide cage is suspended by ropes or chains passing round pulleys to
counter weights so that it can be moved up within or outside of the ventilator tube
when not in use. Sliding rods may also be fitted to the lower end of the guide cage to
be used when required, to descend about the bucket and retain it in position whilst
being filled. Instead of the guide cage sliding within or on the ventilator tube, it
may be hinged at one side, so that it can be swung or turned out of the way.
Dated this Nineteenth day of April 1893.

.AMES JACK GALLOWAY, of 43, Mair Street, Plantation, Glasgow, in the
County of Lanark, North Britain, 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, that is to say :-
My said invention relates to apparatus to a considerable extent of the kind
described in Patent Specification No. 4033 of 1880; and has for its object to
improve various details and arrangements of or connected with such apparatus.
In carrying out the present invention the motor used may be similar to that
described in the said earlier Specification, or any suitable known and simple kind
hoisting engine may be employed, its speed being regulated by means of a
cylinder containing oil or other liquid, or being controlled by valve gear of the
kind employed in steering and starting and reversing engines. The motor may be
arranged to work a pump to supply water for a purpose hereinafter explained. In
some cases in which the height of the lift is not great the gearing may be worked
by hand.
As formerly the lifting gearing is arranged to raise the ashes bucket within a
tube or trunk to a sufficient height to prevent water reaching the top of it through
the discharge tube; but instead of sloping the discharge tube from the highest
point to the side of the ship, the first part of the discharge tube is directed down-
wards and then led to the side with little or no slope. Jets of water are suitably
applied in the discharge tube for moving the ashes along that tube.
When the tube through which the ashes bucket has to be hoisted has its bottom
end at some height above the bottom of the stokehold a movable guide cage is by
this invention fitted to the end of it to guide the bucket up into the tube.
And in order that my said invention and the manner of performing the same may
be properly understood I hereunto append a sheet of explanatory drawings to be
hereinafter referred to and showing my improved apparatus for discharging ashes
from steamboats.
Figure, 1, of the drawings is a plan, and Figures, 2, and, 3, are respectively
an elevation and a sectional elevation as at right angles to each other, of the
apparatus.
Figure, 4, is a horizontal section and Figure, 5, a vertical section of the tube with
the guide cage applied.
In these drawings the same reference letters are used to mark the same or like
parts wherever they are repeated.
As formerly the lifting gearing, A, is arranged to raise the ashes bucket, B,
within a tube or trunk, C, (which will in many cases be that for leading air
down into the stokehold) to a sufficient height to prevent water reaching the
top of it through the discharge tube, D, but instead of sloping the discharge
tube, D, from the highest point to the side of the ship, the first part of the
discharge tube is directed downwards and then led to the side with little or no
slope. The discharge tube, D, when thus arranged is more convenient and
more out of the way of other things. The tipping of the ashes bucket, B, may
be effected in the manner described in the earlier Specification bereinbefore
referred to, and any of the appliances described in that Specification may be
used for moving the ashes along the discharge tube, D. It is however, by the
present invention proposed to employ one or more jets of water suitably applied,
by means of the pipes, E, in the discharge tube, D, for moving the ashes along
that tube, such water being supplied by pumps (not shown) herein before referred
to, or by any available pumps on board the vessel.

page_text: When the ventilator tube or other tube, C, through which the ashes bucket, B,
has to be hoisted, has its bottom end at some height above the bottom of the
stokehold, a movable guide cage, F, is by this invention fitted to the lower end
of it, to guide the bucket up into the tube and to prevent it from swinging
about with the motion of the vessel. This guide cage, F, is suspended by ropes
or chains, G, passing round pulleys, H, to counter weights, J, so that it can be
moved up within or it might be outside of the ventilator tube, C, when not in
use. The counter weights, J, move in vertical pockets, K, on the sides of the
tube, C, to prevent them from swinging about with the motion of the vessel.
Sliding rods, (not shown) may also be fitted to the lower end of the guide
cage, F, to be used when required to descend about the bucket, B, and retain
it in position whilst being filled. Instead of the guide cage, F, sliding within or
on the ventilator tube, C, it may be hinged at one side, so that it can be swung or
turned out of the way.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. The combination with apparatus for hoisting ashes buckets of a discharge
tube for conveying ashes to the ship's side, such tube being fitted with pipes through
which water is forced by pumps to propel the ashes out of it substantially as
herein before described.
2. In apparatus for discharging ashes from steamboats, fitting at the lower end
of a ventilator or like tube a guide cage which is either suspended by counter-
weighted ropes or chains, or is hinged at one side, and is capable of being
withdrawn upwards, or of being turned to one side, substantially as and for the
purposes herein before described.
