PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Syphon Cisterns or Water
Waste Preventers.
I, SAMUEL GEORGE MASON of Dale End Birmingham in the County of
Warwick Brassfounder, do hereby declare the nature of this invention to be as
follows:-
My invention relates to a new method of manufacturing the cisterns or boxes,
and the auxiliary parts in connection therewith.
Hitherto it has been the usual practice to cast the cistern body and internal
parts or to make up the same of sheet metal or other material and to rivet or
otherwise connect the parts together.
My invention consists in the first place of raising, pressing, stamping, drawing,
or otherwise in similar or other suitable manner forming the cistern body out of
one piece of sheet steel, iron, or other metal without any join whatever. The cover
may be produced in a precisely similar way, also the internal parts, with the
exception obviously of the brass work.
In connection with my improved cistern I also propose to finish the same by a
process of enamelling (similar to the present system of enamelling holloware
vessels) either internally or externally of the cistern, or both, as also the internal
accessories where required.
A further improvement consists in making the syphon pipe of steel or iron tube
or other suitable metal in the same manner as described for the other parts.
By my method of manufacture the cistern will be about one half of the weight
only of present ones, and any liability of their bursting in frosty weather is
entirely obviated, moreover by reason of the smoother and clearer surface of the
walls etc. they can be coated by any suitable substance (besides the enamelling)
which will overcome any possibility of contamination by the water, thereby
reducing liability of rusting to a minimum.
Dated this 3rd day of September 1895.

Improvements in the Manufacture of Syphon Cisterns or Water
Waste Preventers.
I, SAMUEL GEORGE MASON of Dale End Birmingham in the County of
Warwick Brassfounder, 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 :-
In manufacturing syphon cisterns or water waste preventers for water closets
and urinals the practice hitherto adopted has been to form the box by casting, or
by riveting the sides and ends together and it has also been the practice to cast
the internal parts.
Cisterns so made however have many disadvantages the chief

exceedingly difficult to ensure uniformity of size, moreover there is considerable
liability to bursting in frosty weather. The surfaces of cisterns which have been
cast are usually very rough and in the case of riveted boxes there is great liability
of leaking and the rivet joints opening owing to pressure by freezing. By my
method of construction I obviate these disadvantages, as I construct the cistern
body by raising, pressing stamping or drawing it out of one piece of sheet metal
and for this purpose I prefer to use sheet steel or aluminium as these metals give
the greatest strength combined with lightness but I may use any other suitable
metal. I may also make the internal parts, that is the stand pipe, the well, the
dome, the bell, and the lever of the cistern in the same way, but for ordinary
purposes it may be found more suitable to form these internal parts by casting.
Another advantage of so constructing the cistern is that a much higher degree
of finish can be obtained for enamelling, and thereby the risk of contamination by
corrosion is more completely obviated.
I am aware that small boxes for purposes other than cisterns, have been made
by raising, pressing, stamping, and drawing but,
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.
In syphon cisterns, or water waste preventers for water closets, and urinals, the
combination of cistern boxes constructed by raising, pressing, stamping, or
drawing, sheet metal, with the internal parts which may either be cast, or made by
raising, pressing, stamping, or drawing, substantially as described.
