I EDWARD GRIFFITH BREWER of 33 Chancery Lane in the County of Middlesex,
Fellow of the Institute of Patent Agents do hereby declare the nature of said
invention for "IMPROVEMENTS IN VALVES OR COCKS TO BE USED IN SEWAGE OR
DRAINAGE WORKS" (a communication to me from abroad by Aime Robert of Gilly,
Belgium, Engineer) to be as follows:-
The special object of this invention is the construction of valves of spherical
form applicable to drainage works, passage of rubbish, sand, slush and like materials.
The valve proper is composed of two hemispheres having a suction tube, an outlet
tube and each a half tube the latter for the suction of pure water.
These two hemispheres are coupled to one another by fixed flanges and bolts
holding between them a sphere having three orifices equal to the opening of the
suction outlet and water tubes.
The normal communication between the slush passage and the pump (being
intended to pump the materials to be transported) is in a straight line, there is a
branch at an angle by which pure water arrives when it is necessary to clean the
pump and the column or when the latter is stopped up.
In case it is simply required to interrupt the arrival of the slush this is effected
by pivotting the sphere either on a quarter or half circle by means of an endless
screw gearing into a toothed wheel or pinion keyed on a piece forming a portion of
the internal sphere.
The upper and lower boxes have circular grooves in which caoutchouc washers
are placed in order to obtain a tight joint. The orifices are bevilled consequently
the valve cannot get wedged for the bevilled parts drive before them the foreign
bodies which present themselves.

I EDWARD GRIFFITH BREWER of 33 Chancery Lane in the County of Middlesex
Fellow of the Institute of Patent Agents (a communication to me from abroad by
Aime Robert of Gilly Belgium, Engineer) 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 refers to the construction of valves of spherical form applicable to
drainage works, passage of rubbish, sands, slush and like materials. The invention
will be best understood by reference to the accompanying drawings,
Figure 1 is a sectional elevation, Figure 2 is an end view, and Figure 3 is a plan
of a sluice valve constructed according to this invention. The valve proper is
composed of two hemispheres A baving a suction tube B, an outlet tube Ċ, and
each a half tube D for the water suction.
These two hemispheres are coupled to one another by flanges E and bolts holding
between them a sphere G having three orifices H each being formed equal to the
opening of the suction outlet and water tubes B, C, D. The normal communi-
cation between the slush passage and the pumps (being intended to pump the
materials to be transported) is in a straight line; there is a branch at an angle or
a tube D by which water arrives when it is necessary to clean the pump and the
column or when the latter is stopped up.
In case it is simply required to interrupt the arrival of the slush this is effected
by turning or pivotting the sphere G either at a quarter or half revolution by
means of an endless screw I gearing into a toothed wheel or pinion keyed on the
spindle J forming a portion of the internal sphere. The upper and lower bearing
boxes K have circular grooves L in which caoutchouc washers M are placed in
order to obtain a tight joint. The orifices H are bevilled consequently the valve
cannot get wedged for the bevilled parts drive before them the foreign bodies which
present themselves.
The essential feature of this invention is the spherical form given to the sphere G.
This spheroidal form prevents all sticking in the body of the valve thereby rendering
the working very easy, for example when the valve is used as a sluice gate for
water and other liquids.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim as
the invention communicated to me, is
First. In sluice valves the employment of two spheres one within the other the
internal one of which is movable and free to turn whereby two or three passages

tially as and for the purposes set forth.
Second. The employment of sluice valves as described as a three way cock
whereby passage is afforded for water or other liquid or material in a straight line
or not substantially as set forth.
