PROVISIONAL SPECIFICATION left by the said Astley Paston Price at the
Office of the Commissioners of Patents on the 22nd December 1883.
ASTLEY PASTON PRICE of 47 Lincolns Inn Fields in the County of Middlesex
Gentleman "IMPROVEMENTS IN RECOVERING AND OBTAINING TIN FROM TINNED
METALLIC SURFACES
This Invention relates to the effecting the recovery and the obtaining of Tin
from the Surfaces of Tinned Metals.
In carrying out my Invention I place the tinned metal or metals to be treated,
such for example as tinned iron, commercially known as tinplate, into a solution of
caustic alkali-such for example as Caustic Soda in such a manner as that it shall
hereafter constitute a terminal of a galvanic or Electric battery, whilst in the same
alkaline Solution a plate of suitable material or substance shall form the other
terminal; so that if a current passes, the tin will be dissolved from the Tinned
Metal or Tin plate, and after the Alkaline Solution, or bath having become
sufficiently saturated with tin, the tin will be deposited on the other terminal and
may be removed from it; or the tin may be separated from the solution by other
means. or the Stannate of Soda or other Stannate thus formed may be employed for
purposes useful in the arts.

This Invention relates to the effecting the recovery and the obtaining of Tin
from the Surfaces of Tinned Metals.
In carrying out my Invention I place the tinned metal or metals to be treated,
such for example as tinned iron, commercially known as tin-plate, into a solution of
Caustic Alkali-such for example as Caustic Soda in such a manner as that it shall
hereafter constitute a terminal of a galvanic or Electric Battery, whilst in the same
alkaline solution a plate of suitable material or substance shall form the other
terminal; so that if a current passes or is made to pass, the tin will be dissolved
from the Tinned metal or Tin plate, and after the alkaline solution or bath has
become sufficiently saturated with tin, the tin may be deposited on the other
terminal as is well understood and may be removed from it; or the tin may be
separated from the solution by other means--Or the Stannate of Soda or other
Stannate thus formed may be employed for purposes useful in the arts.
Having now described and particularly ascertained the nature of my said
Invention and the manner in which the same is or may be used or carried into
effect I would observe in conclusion that what I consider to be novel and original
and therefore claim as the Invention secured to me by the hereinbefore in part
recited Letters Patent is :-
Effecting the removal and the recovering of the Tin existing upon the surface of
what is known as Tin plate substantially in the manner as hereinbefore described.
In witness whereof I the said Astley Paston Price have to this my Specification
set my hand and seal this seventeenth day of June One thousand eight hundred and
eighty-four
