PROVISIONAL SPECIFICATION.
Improvements in Ball Cocks and Syphons for Water Closet Cisterns
or other Vessels.
I, DONALD MACKENZIE, 24 Queens Square Dublin Co. Dublin, Ireland,
Plumber, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved form of ball cock actuated directly from
the ball without the intervention of levers &c. as now generally used--and consists
in mounting the ball on a suitable spindle provided with an indiarubber, metal, or
other valve.
This spindle works vertically in a valve casing fitted with a seating for valve and
inlet and outlet for water and connected with water supply either through bottom
of vessel or otherwise.
To overcome the objectionable noise caused by the water entering the vessel as
at present, I fit a deflector to the outside of the aforesaid spindle of the ball, to
direct the water downwards, and under the surface of the water in the vessel,
thereby rendering the action of the apparatus perfectly noiseless.
For the purpose of adjusting the weight of the ball, spindle, &c. to suit all cases
of varying water pressure, I use either removeable weights or a spring to depress
the ball and open the valve when the water falls below its proper level in the
vessel.
My improved syphon consists in attaching the service or syphon pipe (which may
be bent so as to form a syphon at its upper end or attached to any form of pipe
for the same purpose, or to an internal or external pipe so as to act as a syphon)
to a cylinder which may be placed either horizontally or vertically as may be most
convenient.
This cylinder is fitted with an outlet or discharge opening to basin or pan of
closet and with a piston which when in its normal position, is on the syphon or upper
side of discharge pipe to basin. By pulling the handle or pull or by action of a
moveable seat or other device as at present in use, this piston is caused to move a
sufficient. distance to exhaust the air from the syphon, thereby charging same and
passing the outlet opening to basin, admits the whole contents of cistern to flush
same.
Dated this 11th day of June 1890.

DONALD MACKENZIE 24 Queen's Square in the City & County of Dublin
Plumber 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 improved form of ballcock is designed to dispense with levers etc. as at
present used and to simplify their construction generally.
By preference I construct them as shown in the accompanying drawing in
which
A. A are the inlets A' the outlet B an equilibrium valve connected direct to the
stem or stalk D of the ball E. C is a deflector F F are cup washers and Ga
shaal nin

page_text: When the water in the cistern or tank falls below its destined level the weight
of the ball spindle and valve causes the valve to open, but in cases of very high
pressure, a small additional weight may be added at the end of the spindle at G
or otherwise.nub
The valves may have leather, indiarubber, or metal or other seats and faces, and
the deflector may be formed as a tube or inverted syphon instead of the form
shown.
I do not confine myself to the exact form of valves, or general design shown,
which may be varied in part or whole so as to secure the advantages above
named.
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.
1st. The general design and construction of the valve as shown for the purposes
herein before described..
2nd. The direct attachment of the ball to a vertical spindle for the purposes
herein before described.
3rd. The use of a metallic or other deflector.
