I, JOSEPH HUTCHINSON HARRISON, of 2, Exchange Place, Middlesbrough, in
the County of York, Consulting Engineer, do hereby declare the nature of this in-
vention to be as follows
It consists of the parts hereafter described:-
i
1. A tank into which water is allowed to flow continuously at a rate which may
be graduated according to circumstances.
2. A syphon attached to the tank large enough to drain it faster than the water
flows in.
3. A hollow float which rises & falls with the varying level of the water, but
furnished with an opening so placed as to admit water into its interior when suffi-
ciently immersed.
4. A syphon attached to the float so arranged as to drain it after its descent.
The action of the apparatus is as follows:-
As the water rises in the tank the float also rises until it comes in contact with
a fixed stop at the top of the tank.
The water still further rises until it reaches the opening in the float, the interior
of which then fills until it is heavy enough to sink. In the act of sinking the
float forces the level of the water in the tank above the crown of the syphon which
then commences to work & rapidly drains the tank. At the same time the float
falls to its lowest point & is itself drained by its own syphon ready for its next
ascent.
A reciprocating motion is thus obtained which is applicable to many purposes
where a comparatively slow succession of alternate strokes is desired.

Buoyancy Water Motors.
I, JOSEPH HUTCHINSON HARRISON, of 2, Exchange Place, Middlesbrough, in
the County of York, Consulting Engineer, do hereby declare the nature of this in-
vention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:
It consists of the parts hereafter described:-
-
1. A tank into which water is allowed to flow continuously at a rate which may

2. A syphon attached to the tank, large enough to drain it faster than the water

furnished with an opening so placed as to admit water into its interior when suffi-
ciently immersed.
4. A syphon attached to the float so arranged as to drain it after its descent.
The action of the apparatus is as follows:-
As the water rises in the tank the float also rises until it comes in contact with
a fixed stop at the top of the tank.
The water still further rises until it reaches the opening in the float, the interior
of which then fills until it is heavy enough to sink. In the act of sinking the
float forces the level of the water in the tank above the crown of the syphon which
then commences to work and rapidly drains the tank. At the same time the float
falls to its lowest point and is itself drained by its own syphon, ready for its next
ascent.
A reciprocating motion is thus obtained which is applicable to many purposes
where a comparatively slow succession of alternate strokes is desired.
Referring to the annexed drawing Fig. 1 shows a convenient form of the appa-
ratus. Water is allowed to flow continuously into the cylindrical tank A. by the
pipe B. As the level of the water rises in the tank A, the cylindrical hollow float C
is lifted off the four rests D (two only of which are seen in this view) and continues
to rise until the top of the float comes into contact with the fixed stop .E. The
water level in the tank A, still continues to rise until it reaches the hole F in the
float C, which is very slightly below the top of the syphon pipe G the short leg of
which is attached to the bottom of the tank A, and the longer leg arranged to dis-
charge at a lower level. The water still rising in the tank A flows through the
hole F into the float C causing it to sink and thereby displacing sufficient water in
the tank A to raise its water-level higher than the top of the syphon pipe G which
is thereby set into action and being larger than the inlet pipe B removes the water
from the tank A. The float C sinks in the tank A. till it comes onto the four
rests D, where it remains and becomes filled with water.
Meanwhile the water in the tank A is being drawn out by the syphon pipe G
and as soon as the water level comes below the upper part of the float C, the syphon
pipe H inside of the float C begins to work and draws the water out of the float C
as the water level of the tank A goes down until all the water is drawn out of the
float C and that out of the tank A down to the point where the syphon pipe G
is attached to it, when the syphon pipe G ceases to act.
Water continuing to flow in at B fills the tank A causing the float C to rise again
as before described.
Thus the float C continues to rise and fall automatically giving a comparatively
slow succession of alternate strokes, which, by attaching a rod, tube, chain or wire J
to the upper part of the float C may be used for many purposes where such a motion
is required.
The top of the float C is perforated with holes K to allow of the exit of air when
the float C is being filled with water.
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
'
A self controlled apparatus as above described, whereby water continuously fed
into a suitable tank causes a float to rise and fall alternately, from which power
may be transmitted for many useful purposes.
