PROVISIONAL SPECIFICATION.
Improved Method of and Apparatus for Producing Available
Hydraulic Pressure.
I, ALGERNON JOSEPH YORKE, of No. 1, Princes Square, Bayswater, in the
County of Middlesex, Merchant, do hereby declare the nature of this invention to
be as follows:-
My invention relates to an improved method of and apparatus for producing
available hydraulic pressure, and consists in the combination with an anchored
vessel, of one or more pumps external to the vessel and anchored to the bottom or
slung from the vessel, so that the rise and fall of the vessel, according to the swell
or roll on the water, shall cause the pumps to deliver water under pressure.
In carrying the invention into effect, I provide a pump at, say, each end of the
vessel. Either the pump cylinder or its piston is anchored to the bottom in any
suitable way. Any suitable float or counterpoise may be combined with the pump.
Suitable delivery pipes are led from the pumps into a suitable storage chamber
within the vessel, and from which the water can be drawn as may be required for any
purpose to which water under pressure can be applied.
The operation of my invention is as follows.
As the vessel rises and falls, the pistons of (say) a pair of pumps, one at the bows
and the other at the stern, are worked. Either the pistons are moved up and down
the pump cylinders, or the latter are moved over the pistons.
I do not confine myself to the number of pumps or pairs of pumps which may
be used with any vessel. The details of construction, as well as of their suctions and
deliveries may be of any suitable type according to circumstances and the require-
ments of the invention.

COMPLETE SPECIFICATION.
Improved Method of and Apparatus for Producing Available
Hydraulic Pressure.
I, ALGERNON JOSEPH YORKE, of No. 1, Prince's Square, Bayswater, in the
County of Middlesex, Merchant, 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 :-
My invention relates to an improved method of and apparatus for producing
available hydraulic pressure, and consists in the combination with an anchored vessel,
of one or more pumps external to the same and either anchored to the bottom or slung
from the vessel; so that the rise and fall of the latter according to the swell or roll
on the water shall cause the pumps to deliver water under pressure.
In carrying the invention into effect I provide a pump at, say each end of the
vessel. Either the pump cylinder or its piston is anchored to the bottom in any
suitable way. Any suitable float or counterpoise may be combined with the pump.
Suitable delivery pipes are led from the pumps into a suitable storage chamber
within the vessel, and from which the water can be drawn as may be required for
any purpose to which water under pressure can be applied.
The operation of my invention is as follows:-
As the vessel rises and falls, the pistons of (say) a pair of pumps, one at the bows

page_text: and the other at the stern, are worked. Either the pistons are moved up and down
the pump cylinders, or the latter moved over the pistons.
I do not confine myself to the number of pumps or pairs of pumps which may be
used with any vessel. The details of construction, as well as of their suctions and
deliveries, may be of any suitable type according to circumstances and the require-
ments of the invention.
In order that my invention and the means by which the same is to be carried
into practical effect may be thoroughly understood, I will now describe them in detail,
referring in so doing to the accompanying drawings which are to be taken as part
of this Specification and read therewith.
Fig. 1 is a side elevation illustrating my invention.
Fig. 2 is a plan, and Fig. 3 is a transverse section taken on the line A-B of
Fig. 1.
Fig. 4 is a detail side elevation, partly in section, on an enlarged scale, of one
of the pump gears illustrated in Figs. 1, 2, and 3.
Fig. 5 is a front elevation corresponding therewith.
Fig. 6 is a plan of the suspension brackets.
Fig. 7 is a side elevation of a modified pump gear.
It is to be borne in mind that the above figures are not to be taken as limiting.
the constructional form of my invention, but only as illustrating its nature and
principles and the most convenient methods of applying it. For instance, the
pumps may work through the bottom of the boat instead of being suspended from
the side.
Referring to Figs. 1 to
A is the vessel; and a, a, the fore and aft cables by which it is anchored to the
bottom B, bows on to the swell. Its motion will therefore be a pitching one.
One undulation C is shown as amidships, i.e., half way between the fore and aft
pumps.
The vessel is shewn as fitted with a pump suspended from each bow and one also
from each side as near the stern as practicable.
The details of all the pumps and their gears are duplicates of each other
respectively. They are shewn clearly in Figs. 4, 5 and 6, and are as follows:→
D is a strong bracket or stanchion made fast to the side of the vessel.
E is a float or counterpoise. It is of a sufficient area to present as much
surface to the water above or below it as the case may be, as will tend to
prevent it from being moved out of its normal position by the up or down
motion of the vessel. F is the pump cylinder. Both float and cylinder are
made fast to each other so that they can only move together. G is the pump
piston; and g, its rod. H is a guide ring loosely surrounding the cylinder F,
and
hare a pair of guide rods fast to the said ring by their lower extremities.
The float is bored to allow the rods h h to pass through it; the holes through
which they pass being practically of a larger diameter. i, i are a pair of guides
upon the sides of the pump cylinder in which the rods h, h respectively move.
The upper extremities of both rods h h and of the piston rod are made fast
to the lateral extension d of the bracket D. d¹ is a loop projecting from the
bracket. It serves as a clip to prevent the rods g, h, h from being bent, or moved
outwards from the bracket, and is a second lateral extension adapted to serve
as a distance piece to keep the said rods away from the vessel's side.
J is the suction, and K the delivery pipe. Both are furnished with suitable
non-return valves. The former is long enough for its open end to be always
subinerged. The latter is shewn as led through the vessel's side. It terminates
in a suitable storage vessel (which however is not shewn in the drawings) into
which the water is first pumped, and in which the pressure is subsequently generated
by the continued action of the pumps.
The vessel may be anchored with her beam to the swell if preferred.
The effect of the float in preventing the cylinder from being unduly moved out,
of its position in an upward direction by the pitch or the roll of the vessel, may

page_text: be supplemented by chaining a sufficiently heavy weight to the tail of the pump
cylinder, the chain being preferably just long enough to let the weight rest upon
the bottom. This device is illustrated on the left hand side of Fig. 1.
With the pumps and gear constructed as illustrated in Figs. 1 to 6, the piston is
worked up and down the pump cylinder which remains practically stationary with
reference to its piston.
According to the modification illustrated in Fig. 7, the piston is anchored to the
bottom B by a heavy weight L made fast to the end of the piston rod 9. The
pump cylinder F is suspended from the stanchion D by a ball-and-socket joint f.
fare air-holes to allow of air following after and escaping from before the piston.
I wish it to be distinctly understood that sets of pump gear such as herein before
described in connection with the accompanying figures may be air pumps instead
of water pumps, being fed from the atmosphere instead of from the sea.
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:
The combination of vessel anchored so as to be pitched or rocked, and pumping
apparatus and gear whereby the up and down motion of the vessel shall be the
motor for actuating the pumping apparatus, as and for the purpose set forth.
