nature of the said Invention for "IMPROVEMENTS IN THE FITTINGS OF
BILGE PUMPS AND INJECTION COCKS OF IRON STEAMERS AND SAILING VES-
SELS" to be as follows :-

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Alexander Crichton, in the Great Seal Patent
Office, on the 14th October 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
ALEXANDER CRICHTON, of 4, Saint George's Terrace, Park Road, Liver-
pool, in the County of Lancaster, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of April, in the year
of our Lord One thousand eight hundred and fifty-three, in the six-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Alexander Crichton, Her special
licence that I, the said Alexander Crichton, my executors, admi-
nistrators, and assigns, or such others as I, the said Alexander
Crichton, my executors, administrators; and assigns, should at any
time agree with, and no others, from time to time and at all times.
thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom
of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for "IMPROVEMENTS IN THE FITTINGS OF BILGE
PUMPS AND INJECTION COCKS OF IRON STEAMERS AND SAILING VESSELS,'
upon the condition (amongst others) that I, the said Alexander
Crichton, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said In-
vention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Alexander Crichton, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof (that is to say):
This Invention consists of applying a drain perforated with nume-
rous holes on the keel, and under one or more floorings, into which
drain the pipes of bilge pumps and bilge injections are to be led.and
fitted to.

page_text: Having thus stated the nature of my said Invention, I will proceed
to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1, shows a cross or midship section of an iron steam ship or
sailing vessel, Figure 2, is a longitudinal section, taken through the
centre of the vessel; and Figure 3, is a plan. In each of these
Figures the same letters are used to indicate the same parts. a, a, is a
perforated cast iron drain, which, in building a ship or vessel, is placed
on the keel under the floor; b, b, are doors, which can be lifted, when
desired, to allow of drawing a chain with a brush thereon to and fro
within the drain a, to clear and clean the interior'; d, d, are pulleys,
which guide the chain when being moved to and fro within the
drain a; on the drain are branches e, e, to which the bilge pumps and
the bilge injection pipes are attached. By these arrangements it will
be seen that each perforated drain is made to communicate with the
spaces between several frames or floors; and, when desired, the drain a,
may be placed above the frames, as well as under them. The drain a,
is perforated with numerous holes, which increase in diameter inwards,
so as to insure them from being stopped up.
Having thus described the nature of my Invention, and the manner
of performing the same, I would have it understood that what I claim
is the mode of constructing and applying perforated drains a, a, com-
municating with several spaces between the frames and floors, and also
the apparatus above described for cleaning them.
In witness whereof, I, the said Alexander Crichton, have hereunto
set my hand and seal, this Eleventh day of October, in the
year of our Lord One thousand eight hundred and fifty-three.
ALEXR CRICHTON. (L.s.)
