IMPROVEMENTS IN THE. MANUFACTURE OF TIN PLATES
Year: 1882

page_text: LETTERS PATENT to Clement Sankey Best Gardner, of Neath, in the County of
Glamorgan, Manager of Works for an invention of "IMPROVEMENTS IN THE.
MANUFACTURE OF TIN PLATES"
PROVISIONAL SPECIFICATION left by the said Clement Sankey Best
Gardner at the Office of the Commissioners of Patents on the 28th March
1882.
CLEMENT SANKEY BEST GARDNER, of Neath, in the County of Glamorgan,
Manager of Works "IMPROVEMENTS IN THE MANUFACTURE OF TIN PLATES"
My invention relates to an improved method of manufacturing crystallized tin
plates, whereby they may be produced more expeditiously and more economically
than hitherto; and it consists essentially in chilling the plate at a certain point of
its manufacture, in lieu of first completing the manufacture of the tin plate and
then producing the crystallization; as is now ordinarily practised.
In the usual method of tinning iron sheets, they are first plunged into hot
grease, then into molten tin, then passed through rollers working in molten tin
and lastly allowed to cool; the tin plate being then finished.
Now, when I desire to produce a crystallized tin plate, I direct by means of a
large syringe with a fine rose or in any suitable manner, a spray of water upon the
plate after it issues from the rollers working in the molten tin (the tin upon the
plate being still in a melted state); having chilled the plate by this shower bath
I then dip it into an acid solution and the crystallization is thus produced in the
manufacture of the tin plate.
