ROBERT HASWELL 11 Union Street Hartlepool Durham Naval Architect do hereby
declare the nature of this invention to be as follows :-
It consists of a reservoir or tank made of any material and shape having any number
of holes for the influx and efflux of the fluid. Inside and made to fit close to it, is a
float made like a bottle with the mouth down, and so arranged that with the confined
air it rises to the top upon guide rods, with the fluid that is admitted into the tank.
When it is near the top the influx fluid is stopped, and the air allowed to escape
whereby filling itself with the fluid, loses its buoyancy and acting with the head of
the fluid causes a pressure at the efflux hole, the fluid being prevented from getting
above it by means of leather and other packing round the edges. When near the
bottom the fluid inside the float escapes thro' and air admitted by a valve in the
bottom of the tank, and regains its buoyancy.

page_text: ROBERT HASWELL 11 Union Street Hartlepool Naval Architect, 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 consists of a reservoir, or tank having inside a weight constructed so
as to float on a fluid as it flows into the reservoir or tank, and to lose its buoyancy when
at or near the top, thereby causing hydraulic accumulation.
It is shewn on the drawing in sectional elevation.
The reservoir or tank is figured A, and made of any material in any shape, or
number of parts to construct the whole, having any number of holes B and C in or
near the bottom, for the influx and efflux of the fluid respectively and so arranged,
that while one is open the other is shut by any contrivance, or one hole can be made
to answer both purposes.
Inside, and made in any shape, thickness or number of parts is the weight D
corresponding to the reservoir, or tank at its sides, and so made that the leather
collar, or other packing E can be fitted. Inside, or fitted above or below it, is a
chamber F of any size, or shape, through the bottom of which is an opening
having a projection G to which is fitted a leather collar, or other packing H by any
contrivance.
The leather collar, or other packing H may be fitted round the mouth of I.
Corresponding to the projection G and in the bottom of the reservoir, or tank is
the pipe or box I containing a valve worked by a lever and rod. The projection G
may be fitted complete to the mouth of I, and to work into the chamber F.
Through the top of the chamber F, a valve K, or cock is fitted, opened and shut by
any contrivance.
The fluid flows into the reservoir, or tank A thro' the hole B. The weight D on
account of the confined air, or other gas, inside the chamber F floats until at or near
the top of the reservoir, or tank, where the air or other gas is allowed to escape
through the valve K opened by the rod L, allowing the chamber to be filled with the
fluid, whereby the weight loses its buoyancy and causes an accumulation of fluid,
which is prevented from getting above by means of the leather collar, or other
packing E.
The hole B is now closed, and C opened for the efflux of the fluid.
When the weight D is at, or near the bottom of A the projection G goes into I,
and opens the valve by bearing on the lever or rod allowing the fluid inside the
chamber F, to escape, and at the same time the fluid inside A being prevented by the
leather collar, or other packing H fitted to G. The valve K is opened by atmospheric
pressure, or other means to admit a fresh supply of air, or other gas into the chamber,
so that the weight D regains its buoyancy.
The sides of the weight D may be extended above the top or below the
bottom.

page_text: It may be made to work up and down upon guide rods, which may have holes
down the interior for the same purpose as the valve K.
The opening G may be closed by a ball float, cock or other contrivance after the
chamber has filled itself.
Any number of chambers F with openings, and air valves may be fitted.
Gun turrets can be raised and lowered by being mounted upon the weight D.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what I
claim is:
1. For the arrangement of a weight to rise inside a reservoir, or tank, by means of
air, or other gas, confined in a chamber, fitted to, or inside it.
2. For the arrangement whereby the weight loses its buoyancy.
3. For the arrangement whereby hydraulic power is accumulated.
4. For the arrangement whereby the weight regains its buoyancy.

day of
1888.
