Improvements in the Method of and Means Employed for Removing
Ashes on Board Ship.
I JOHN BRIERLEY HOWARD of the Firm of Brierley & Howard Penny Bank
Chambers Halifax in the County of York Patent Agents do hereby declare the
nature of this invention which has been communicated to me by H. Wehner
of Kiel in the Empire of Germany and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to improvements in the method of and meaus employed
for removing ashes and spent fuel from ships especially during the navigation or
progress of same.
Such being the nature and object of my said invention the following is a
complete description of same reference being had to the accompanying drawings in
which:-
Figs. 1, 2, 3 and 5 are sectional side elevations of apparatus for purpose herein
described.
Fig. 4 is a plan view of the apparatus.
Fig. 6, 7, 8 and 9 are details drawn detached in order to shew their construction
more clearly.
Fig. 10 is a sectional side elevation of the improved apparatus drawn to an
enlarged scale.
Figs. 1 and 5 shew a box "g" fastened in the ship on the shell of same and
placed under the water-level and such box may be opened or closed either at the
top or bottom.
In order to have the ash removing apparatus working safely and free from
danger it is fitted as follows:-
The top of the box or vessel "g" is closed with a cover "1" (Fig. 3 and 4)
which is kept down by means of a bolt or strap "6" and catch "u" (Fig. 3
to 5).
Upon the vessel "g" there is fixed a cockbox with cock "a" (Fig. 3 to 5)
provided with a side opening which may form a communication between the
vessel "g" and the conducting tube "m (Fig. 1 to 4 and 6 to 7) which leads
to a valve "v" (Figs. 1 and 2) or communicates with a channel "t" above the
lower valve (Fig. 3 to 10) the cock "a" may also be put in communication
with the conducting tube "" (Figs. 2, 4, 6 and 7) leading to an air or water
pressure pump or to a steam boiler by means of which a downward pressure may
be exerted on the contents of the vessel "y," or the cock may communicate with
the atmospheric air by means of a tube "c" (Figs. 4, 5 and 7). The vessel "g" is
closed at its lower end by a valve "k" (Figs. 3 and 5) which may be turned
outwardly and opened by means of connecting gear. A second valve "42"
(Figs. 3, 5 and 10) above the lower valve "k" generally remains open, but may
be closed by drawing on the chain "z" (Figs. 3, 5 and 10) as shewn by the dotted
line in Fig. 3 so that the vessel "g' can thereby be closed.
The valve ""may be employed when, in case of an accidental failure of the
lower valve "," the water enters the ship by the open upper valve "k" in which
case the rising water raises the float "s higher and higher.
The lower valve "3" the cock "a" and the upper cover are kept locked by the

page_text: disc "a" fixed on the cock "a" (Fig. 3 to 7 and 10) in the following way :-The
disc "x"
may be seen by Figs. 8 to 9 (Fig. 8 presenting a section on line "A. B"
of Fig. 4) consists of two single discs of the same thickness fastened flatly one above
the other, rigidly on the cock. This disc only allows the spindle "4" to be turned
(Fig. 3 to 7 and 10) and in consequence the valve "3" to be opened or closed
when the cock "a is in the position shewn in Fig. 6 as then the bracket "o"
is not prevented moving up and down the disc segment (Fig. 6) by means of
its screw.
Beneath the directing handle of the bracket "o" there is a T-shaped piece
(Fig. 8) sliding in a sledge fastened on the cock box in order to allow only an up
and down movement of the bracket.
On the other hand the bracket "o "in its lowest position (valve "3" open)
(Fig. 4) only allows the cock to be turned from this position in the direction of the
arrow and until the position shewn in Fig. 6 is obtained and not further.
When the valve "3" is closed the bracket "o o" rises at the same time and
allows the cock to be still more turned, as now the upper part 3. 2 of the disc ""
may slide through the bracket until the position shewn by Fig. 7 is attained.
The catch "u" may now be removed, the bolt "6" raised and the cover "1"
opened.
Suppose the apparatus is in action so that the single parts are in the position
shewn in Figs. 3, 4 5 and 10 it will be clearly seen from Figs. 1 and 2, that, during
the navigation of the ship in the direction of the arrow the water pressing against
the valve "3" with a great pressure, will pass into the vessel "g" by the
valve "" and passing by the cock "a" (Figs. 3, 4 and 10) will then press the
ashes out.
After the ashes are removed from vessel "g" in order to fill it again it is
necessary to shut the valve "3" and this is done by the bracket "o griping
the disc ""(only possible in case the cock "a" is turned till it is in the
position of Fig. 6). Now the valve "3" may be turned inwards by turning the
spindle "" and consequently the vessel "g" closed at the bottom.
The bracket "o" rises to its highest position and therefore allows the cock "a"
to be turned into position Fig. 7.
Instantly the water which is contained in vessel "g" above the mouth of the
tube "c will by the air pressure stream out by the tube "c." If this ceases
very soon it may be concluded, that the lower valve "3" fits tightly and then the
cover "" may safely be opened as soon as the bolt 6 (Fig. 3) and catch V are in
position.
Now the vessel g is ready for again filling with ashes. A grating "" (Fig. 3)
prevents throwing in of too large pieces of slack. Water remaining in the vessel
will cool down the hot ashes and finally will be obliged to overflow by the ashes
cast in the vessel. As soon as the vessel is filled the cover "k" is placed on it,
and the bolt or strap "6" and catch "" are fixed. The cock "a
turned in an opposite direction to the position Figs. 6 and 4 the thickness of the
upper and the lower part of the disc "a" (Fig. 7) prevents a further turning to
the right.

в до
When in the position Fig. 6 the valve "k" has to be opened before the
vessel "g
can be put in communication with the conducting tubes "m" or
by means of the cock "a."
In order to prevent the backwater entering by the tube "m" and losing
considerable power it may be conducted into the vessel "g" below as is shewn by
the arrows in Fig. 10.
The locking is then effected by interposing rods "h" (Fig. 10).
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
An natur

page_text: navigation consisting of a valve "" opening outwards in the direction of the
course, said valve, when open, forming a guide or breakwater so that the water
enters the vessel "g" with increased pressure by the valve or channel "t" and
the pipe
passing to the ashes as and for the purpose herein described.
2. The method of and means employed for controlling the apparatus as herein
described and substantially as illustrated by the annexed drawing.
"
3. The general construction arrangement and combination of part constituting
the improved apparatus operated and operating as and for the purpose herein
described and substantially as illustrated by the annexed drawings.
