Complete Specification Left, 23rd July, 1900-Accepted, 25th Aug.. 1900
Improved Apparatus for Discharging or Conveying Ashes and the like
out of the Stokeholds of Vessels or Ships.
I, HENRY COUSINS STEPHENS, of "Ravenstone," Corbridge, in the County of
Northumberland, Clerk, do hereby declare the nature of this invention to be as
follows:
This invention relates to an improved apparatus for discharging or conveying
ashes and the like out of the stokeholds of vessels or ships into the sea or vessel
alongside. The apparatus consists of an endless chain or band with buckets at
equal intervals, with approximately vertical motion, the driving sheave being at
the top and enclosed in a suitable casing, the whole constituting an elevator:
a box or hopper in the bottom of the elevator and a shoot from the top of the
elevator to the discharge hole in the side of the vessel preferably above the water
level. A flap valve or door opening downwards is placed in the shoot in a
suitable position to prevent the ingress of the water. The elevator driving pulley

is on a shaft which passes from the stokehold to the engine room.
provided with fast and loose pulleys, and gear for shifting the belt which conveys
the motion from the main engine shaft or propeller shaft to this shaft. When
the apparatus has been set in motion by putting the belt on the fast pulley the
ashes are shovelled into the box at the bottom of the elevator, from which they
are lifted in the buckets and tipped into the shoot and so into the sea or vessel
alongside. Instead of driving the apparatus from the main engine shaft, a small
auxiliary engine may be provided for driving it. Provision may also be made
for working either arrangement by hand power in case of necessity.

what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-

suitable position to prevent the ingress of the water. The elevator driving pulley
is on a shaft which passes from the stokehold to the engine room. This shaft is
provided with fast and loose pulleys, and gear for shifting the belt which conveys
the motion from the main engine shaft or propeller shaft to this shaft. When
the apparatus has been set in motion by putting the belt on the fast pulley the
ashes are shovelled into the box at the bottom of the elevator, from which they
are lifted in the buckets and tipped into the shoot and so into the sea or vessel
alongside. Instead of driving the apparatus from the main engine shafi, small
auxiliary engine may be provided for driving it. Provision may also be made
for working either arrangement by hand power in case of necessity.
The annexed drawings are intended to show a convenient mode of performing
the invention.

Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that
what I claim is:-
:-
The elevator apparatus for discharging and conveying ashes and refuse from
stokeholds consisting in the combination of an endless chain or band
furnished with buckets worked over a driving sheave at the top,
with a nopper at the bottom, a shoot from the top of a suitable casing placed over
the driving sheave to the discharge hole in the vessel, and a flap valve or door,
placed in said shoot to prevent ingress of water, all substantially as described and
illustrated and for the purposes set forth.
