The object of this Invention is to effect economy in the manufacture
of articles of tin ware, and in the consumption of tin or tinning alloy
used in the preparation of tinned plates.

page_text: Tinned plates as at present sold in the market are of oblong or square
form, so that when pieces of the desired shape for the manufacture of
useful articles of tin ware are cut or punched from them, there must
necessarily be much waste not only of sheet iron in the form of scraps,
but of the tin or alloy with which such scraps are coated. This waste is
obviated according to this Invention by first cutting or punching from
sheet iron pieces of the shape desired for conversion into parts of articles
of tin ware, and then tinning the pieces preparatory to such conversion.
For example, the pieces of sheet iron may be of the shape of a crescent,
hexagon, triangle, segment of a ring, circle ellipse rhombus, lozenge,
trapezium, or other suitable form to meet the requirements of different
articles of tin ware, the plates being subjected to the tinning bath after
being thus cut to shape, and before they are used in manufacturing tin
articles.
Economy in the consumption of tin or tinning alloy must necessarily
be the result of this plan of first shaping and subsequently tinning sheet
iron pieces. The pieces thus tinned after they are cut to shape possess
another prominent advantage, which distinguishes them from similarly
shaped plates cut from ordinary tinned sheets. In the latter the iron is
necessarily exposed at the edges wherever the sheets have been applied,
whereas this exposure is prevented in carrying out this Invention for
both sides, and all the edges of every plate are coated with tin, and thus
facilitate the making of perfectly soldered joints.
The improved tinned plates of a proper size and shape for conversion
into standard articles of tin ware without shearing may be sold to
manufacturers whose operations will be materially facilitated.

page_text: of our Lord One thousand eight hundred and seventy-five, in the
38th year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Henry Johnson, Her special
license that 1, the said John Henry Johnson, my executors, admini-
strators, and assigns, or such others as, I, the said John Henry
Johnson, my exccutors, administrators, or assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN TINNED PLATES AND IN THE MANUFACTURE OF THE SAME," a
communication to me from abroad by George Edwin Taylor, of Phila-
delphia, Pennsylvania, United States of America, upon the condition
(amongst others) that I, the said John Henry Johnson, my executors or
administrators, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Henry Johnson, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in
and by the following statement, reference being had to the accom-
panying Drawings, and to the letters and figures marked thereon, that
is to say :-
-
The object of the said Invention is to effect economy in the manu-
facture of articles of tin ware, and in the consumption of tin or tinning
alloy used in the preparation of tinned plates.
Tinned plates as at present sold in the market are of oblong or square
form, so that when pieces of the desired shape for the manufacture of
useful articles of tin ware are cut or punched from them, there must
necessarily be much waste not only of sheet iron in the form of scraps,
but of the tin or alloy with which such scraps are coated. This waste is
obviated according to this Invention by first cutting or punching from
sheet iron pieces of the shape desired for conversion into parts of articles
of tin ware, and then tinning the pieces preparatory to such conversion.
In the accompanying Drawing are shewn a few examples of pieces of
sheet iron of different forms of plates to meet the requirements of

page_text: different articles of tin ware, the plates being subjected to the tinning
bath after being thus cut to shape, and before they are used in manu-
facturing tin articles.
Economy in the consumption of tin or tinning alloy necessarily results
from this plan of first shaping and subsequently tinning sheet iron
pieces. The pieces thus tinned after they are cut to shape possess
another prominent advantage, which distinguishes them from similarly
shaped plates cut from ordinary tinned sheets. In the latter the iron is
necessarily exposed at the edges wherever the sheets have been severed,
whereas this exposure is prevented in carrying out this Invention, for
both sides and all the edges of every plate are coated with tin, and thus
facilitate the making of perfectly soldered joints.
The improved tinned plates of a proper size and shape for conversion
into stardard articles of tin warc without shearing may be sold to
manufacturers, whose operations will be materially facilitated.
Having now described and particularly ascertained the nature of the
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 herein-before in part recited Letters Patent is,-
First. As a new article of manufacture and commerce plates of sheet
iron tinned on both sides and at all the edges, and shaped for conversion
into or for forming parts of articles of tin ware, without being sheared
prior to such conversion, all as set forth.
Secondly. The mode herein described of preparing plates of tinned
iron for the manufacture of tin ware, that is to say, first cutting the
plates from sheet iron to the desired shape and then tinning the shaped
plates, as set forth.
In witness whereof, I, the said John Henry Johnson, have to
this my Specification set my hand and seal, this First day of
December, One thousand eight hundred and seventy-five.
J. HENRY JOHNSON. (L.S.)
