Stafford Tin House Superintendent for an Invention of "IMPROVEMENTS IN

"IMPROVEMENTS IN THE MANUFACTURE OF FLUXES OR MATERIAL USED IN THE
PREPARATION OF PLATES TO BE COATED WITH TIN, TERNE, AND OTHER METALS"
Heretofore attempts have been made to produce a flux for the preparation of
tin plates from muriatic acid and spelter but this material after a time has been
found to eat into the iron causing defects to appear on the surface of the plates
and consequently to reduce their value; now according to our Invention we treat
muriatic acid and spelter or zinc in such manner that the injurious properties are
removed from the acid and the plates after coating are not liable to deterioration
as heretofore
According to our Invention we take spirits of salts or muriatic acid and place
the same in an earthenware or other pan of convenient size to contain the required
quantity and a sufficient amount of spelter or zinc is. put into the acid to complete
the process of boiling it, more spelter or zinc may if required be added to the acid
until the boiling ceases, after which it is allowed to rest and settle, it is then
placed in a receptacle and a quantity of charcoal and lime or chalk or magnesia or
the carbonates of any of the alkaline earths is or are added to it the whole viz the

Patent Office on the 20th October 1883.
HENRY FRANCIS TAYLOR of the firm of Taylor Struvé Eaton and Price of Neath
and Briton Ferry, both in the County of Glamorgan, Mechanical Engineers and
GEORGE LEYSHON of Tividale in the County of Stafford, Tin House Superintendent

Heretofore attempts have been made to produce a flux for, the preparation of
tin plates from muriatic acid and spelter, but this material after a time has been
found to eat into the iron causing defects to appear on the surface of the plates
and consequently to reduce their value, now according to our invention we treat
muriatic acid and spelter or zinc in such manner that the injurious properties are
removed from the acid and the plates after coating are not liable to deterioration
as heretofore.
.
According to our invention we take spirits of salts or muriatic acid of 26 degrees;
Twaddell and place the same in an earthenware or other pan of convenient size to
contain the required quantity, and a sufficient amount of spelter or zinc is put into
the acid to complete the process of boiling it, more spelter or zinc, may, if required
be added to the acid until the boiling ceases, or the muriatic acid and spelter or
zinc may be at the same time further boiled by the action of fire on the cauldron
or pot, after which it is allowed to rest and settle. A suitable proportion for some
cases is about 5 of muriatic acid by weight to 1% of spelter. The flux is then
placed in a receptacle and a quantity of charcoal and lime or chalk or magnesia, or
the carbonates of any of the alkaline earths is or are added to it, the whole vis the
acid, spelter or zinc, charcoal and lime or its equivalent are well mixed together
and then allowed to, settle and when clear it is run off; all acid and corrosive
properties being thereby removed and it is ready for use. About one half pound
of lime and pound of charcoal per gallon of the liquid are approximate
proportions

page_text: Sometimes the charcoal may be dispensed with and sometimes during the boiling
action of the muriatic acid and the spelter or zinc we set fire to the gases which
escape until the burning qualities or gases are exhausted or consumed.
In using this material is a flux we pour a small quantity of grease on the surface
of the molten metal and then add a sufficient quantity of the composition treated
in the manner we have before described although in some cases the grease may be
altogether dispensed with.
The aforesaid flux is especially suitable for and used with a flux box and tinning
pot described in the Specification of our Patent dated 4th May 1882 N° 2106.
Having now described the nature of our said invention and in what manner the
same is to be performed we declare that we are aware it has heretofore been
vaguely proposed to make a flux of chloride or sulphate of zinc with other sub-
stances such as common salt, chloride of lead and manganese but such a flux is
quite unsuitable, but we claim as our Invention :-
A flux consisting of spirits of salts or muriatic acid and spelter or zinc treated
by boiling and treated subsequently with charcoal and lime, chalk or magnesia or
with the carbonates of alkaline earths all substantially as and for the purposes
described.
In witness whereof I the said Henry Francis Taylor, for myself and on behalf
of the said George Leyshon have hereunto set my hand and seal this Eighteenth
day of October in the year of our Lord One thousand eight hundred and eighty-
three.
