I HENRY HARRIS LAKE of the firm of Haseltine Lake & Co. Patent Agents
Southampton Buildings, in the County of Middlesex 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 :-
This invention relates to bilge water pumps and consists in the novel construction
and arrangement of parts hereinafter more fully set forth.
In the accompanying drawings
Figure 1. is a longitudinal sectional view of my invention with the lower point of
the pump set in position.
Figure 2 is a longitudinal sectional view of the same with the lower point of the
pump drawn up against the bottom of the vessel.
Figure 3. is a longitudinal sectional view of the same showing the manner of
protecting the lower point of the pump in rivers and shallow waters in which case the
lower point of the pump pipe is made of some flexible material.
Figure 4. is a top view of the netting made of iron, steel wire, or other suitable
material.
Figure 5 is a view showing the rear face of the lower end of the pump pipe and of
the strainer.
Figure 6. represents a cover to close the upper end of the pump so that should the
valve fail to operate from any cause, it will prevent the water from rising into the
vessel.
Figure 1 represents the pump in working order when the vessel is passing through
the water, and will drain in proportion according to the speed, and will drain according
to the diameter of the pump, and the length in proportion to do its work.
pump
The consists of a tube a, which is divided into two parts and hinged together
by a hinge b, just below the bottom of the vessel. The upper part of the tube a, has

page_text: extending from its upper end a flange by which it is secured to a solid timber a¹, or,
in case the bottom of the vessel is made of iron, the said tube a, may be secured
directly to the inner face of the bottom of the vessel. The lower end of the tube a³,
has its rear side cut off at an angle leaving the front coming down to a point. The
hinged part of the tube a' has secured in its front side, by any usual method, a
circular brace a, the free end of which passes through an opening c¹, in the bottom of
the vessel, thence through c², which is a rubber plate or other suitable stuffing to keep
the vessel from leaking at this point. c³ is a sleeve through which said brace c,
passes, and is secured in place by a pin which passes through the perforation c*, in
said brace and a corresponding perforation in said sleeve. The free end of the
brace c has its upper end turned out squarely forming an arm d, which is adapted to
be hooked over the arm d', of the bar d, one end of which is secured to the bottom of
the vessel in rear of the pump. Over the top of the pump and inside of the vessel
there is secured a strainer e, made of suitable material to prevent any large substances
from running into the pump and choking it. At the lower end of the shell or pipe a,
is secured another network e¹. to prevent drift wood, or any large substances from
passing up into the pump and choking it. In the said pipe a, and near its upper end
is secured two hinged valves f, which, when the vessel is in motion and the pump is
in operation, fall down and rest against the block f¹, which is large enough to hold
them out at a considerable angle so that when the vessel stops, the force of the water
will throw them back against the shoulder f, inside the pipe.
When it is desired to unship the pump, I draw up through the bottom of the vessel
the circle c, which brings the hinged end a² of the pump up against the bottom of
the vessel so that the drift wood will shear off. The arm d, of said brace is hooked
over the arm d¹, of the bar d³, which holds the said point a², up in place against the
bottom of the vessel, and a pin is then put through the perforation c³, and the
sleeve c³, which makes an additional fastening.
The bilge water pumps when made for vessels that navigate rivers or other shallow
waters have their lower end a² made of flexible material and the vessel has on its
bottom a recess g, into which the said flexible end of said pipe may be drawn until its
rear or lower face is flush with the bottom of the vessel. In all other respects it is
like the one above described. The operation of the pump is as follows:
When a vessel moves forward the lower end of the pipe ploughing through the
water leaves behind it a track and produces suction which draws the water from the
bottom of the vessel into the stream. When the vessel stops, the hinged valves f, are
immediately closed by the pressure of the water below as no water escapes up through
them into the vessel, because they are made perfectly water-tight. When I do not
wish to operate the pump, I draw the lower end of the pipe up against the bottom of
the vessel as above described.
The upper end of the pipe a³, is adapted to fit in the collar a³, in the lower end of
the pipe a, so that it is perfectly water tight.
When a vessel is standing still as shown in figure 2, the valves are closed and rest
against the collar or flange f¹, thus stopping all water from coming into the hull.
This pump is made of brass, copper, or other suitable material for lakes, or seas, and
can be hung up in the holds of vessels to be used on short notice by the help of a
diving armor to make connection with the circle, and with the shell or pipe a.
These pumps are to be made of suitable sizes varying with the tonnage of the
vessel.
I purpose to secure to the bottom of the vessel, particularly those that are designed
for rivers or other shallow waters, a guard or protection in front of the pump to keep
it from being broken by stumps, logs, or other obstacles.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is:
First. A bilge water pump consisting of the shell a, secured in the bottom of the
vessel, having on its interior face the shoulders f³, and near. its lower end screen or

page_text: strainer e¹ hinged in the centre of said shell a; the valves f, held open by a block f¹,
and adapted to shut up against the shoulder f; the lower pipe a², secured to the
lower end of shell a, and having its rear side cut off at an angle; circular brace c
having perforations c, and c, and on its free end an arm d, one end secured in the
lower end and front side of the pipe a³, and its free end working through an opening c¹,
in the bottom of the vessel, through collar e, and sleeve c³; bar d³, one end secured to
the bottom of the vessel, its arm d³, adapted to hold the arm d, of brace c, substantially
as shown and described.
Second. A bilge water pump consisting of the shell a, secured in the bottom of the
vessel, having on its interior face shoulder f, and near its lower end strainer e³, and
hinged in its centre valves f, held open by block f, and adapted to shut up against
said shoulder f; lower pipe a³, fitted to the lower end of shell a; circular brace c,
having one end secured in the lower end and the front side of pipe a³, its other end
working through opening e', in the bottom of the vessel, and sleeve c³ provided with
suitable stuffing; arm d, adapted to fit over arm d¹, of bar d², or other equivalent
fastening substantially as shown and described.
