PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Discharging Ashes from Ships
and Vessels.
We WILLIAM ADAMSON of Langham Tower Sunderland Shipowner and
THOMAS ROBSON LEE, of No. 20 Azalea Terrace South, Sunderland aforesaid,
Ship Broker, do hereby declare the nature of our said invention to be as
follows:-
The object of our invention is to effect improvements in apparatus for discharging
ashes from ships and vessels.
Our invention as applied to the stoke holds of steam vessels, consists in fitting
endless or other chains or ropes, actuated by a winch, and carried up to a shoot
fitted above the deck to receive buckets fixed to the chains.
The winch for actuating the chain, is preferably fitted in the stoke hold, and the
bucket is fixed to the chain or rope in such a manner that by the action of the
winch the bucket, filled with ashes, is raised up to the covered shoot. The point
of attachment of the bucket to the chain is so arranged that, when it arrives at the
upper end of the lift, it is turned over, and thereby caused to discharge the ashes
into the shoot, from whence the ashes are carried overboard.
The tilting of the bucket may be effected by weights, check lines, or other
suitable means, and the return of the bucket to its normal position is effected by
similar means.
The apparatus is modified to suit the position of the stoke hold, or other part of
the vessel where the accumulation of ashes or other refuse takes place, and the
most convenient part of the vessel for discharging the ashes overboard.
Two or more sets of apparatus may be fitted in a large vessel, as near the ashpits
of the furnaces as possible, to save labour.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Discharging Ashes from Ships
and Vessels.
We, WILLIAM ADAMSON, of Langham Tower, Sunderland, Shipowner, and
THOMAS ROBSON LEE, of No. 20 Azalea Terrace South, Sunderland aforesaid,
Ship Broker, do hereby declare the nature of our said invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The object of our invention is to effect improvements in apparatus for discharging
ashes from ships and vessels.
Our invention, as applied to the stoke holds of steam vessels, consists in fitting
endless or other chains or ropes, actuated by a winch, and carried up to a shoot
fitted above the deck to receive buckets fixed to the chains.
And in order that our said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which
similar figures of reference indicate corresponding parts.

page_text: Fig. 1 is a thwart-ship sectional elevation, showing one method of fitting a steam
vessel with our invention.
Fig. 2 is a side view of a bucket and fittings, drawn to a larger scale.
Fig. 3 is a front view of the same, and Fig. 4 is a horizontal view.
5 is a guide bar, preferably formed of H iron, secured in a vertical position, and
extending from the floor of the stoke-hold to the mouth 6 of the shoot 7. 9 is a
slide block, fitted to slide freely up and down the guide bar 5. The slide block 9
carries a semicircular head 10 and two vertical bars 11, 11, having forks 12, 12,
and swing stops 13, 13. 14 is a bucket fitted with pivots or trunnions 15, 15, about
one-third from the bottom. These pivots work in the forks 12, and thereby
support the bucket 14. 16 is (preferably) a steel rope. The lower end of this
rope is secured to the slide block 9, a groove being formed in the block to receive
the rope. The rope 16 is carried up and passes over a pulley 17 fitted to the upper
end of the bar 5. The rope then descends to the winch 19, passing over any
necessary pulleys, as shown at 18.
The shoot 7 is fitted at a suitable angle to enable the ashes to fall through it to
the outside of the vessel, the end 8 being fitted with a flap valve to permit the
escape of the ashes and prevent an indraught. The shoot may be of any convenient
form, and either curved or straight, the form and arrangement being varied to suit
the build of the vessel. In Fig. 1 a ventilator tube 20 is shown, fitted with a
cowl 21, to form a wind shaft. The upper end of the shoot is attached to the
tube 20, and the lower end to the ship's side.
The ashes are filled into the bucket in the stoke-hold. The bucket is then
hoisted up by the winch 19, until the bucket reaches the position shown at 22 in,
Fig. 1. The upper end of the bucket being then free of the bar 5, is thrown over
by a bent bar 23, as shown, and, after being emptied into the shoot, the bucket
rights itself on being lowered again. The tilting and righting of the bucket may
be effected by weights, check lines, or other suitable means, instead of that above.
described.
The apparatus may be modified to suit the position of the stoke-hold, or other
part of the vessel where the accumulation of ashes or other refuse takes place, and.
the most convenient part of the vessel for discharging refuse matters overboard.
Two or more sets of apparatus may be fitted in a large vessel, preferably as near
the ashpits as possible, to save labour.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
1. In apparatus for discharging ashes from ships and vessels, the combination of
a bucket pivoted to a frame, capable of being hoisted by chains or ropes; appliances
for tilting the bucket; and an enclosed shoot for conveying the ashes overboard;
substantially as hereinbefore described and illustrated by the drawings.
2. The improvements in apparatus for discharging ashes from ships and vessels,
substantially as described.
