Improvements in and relating to the Manufacture of Lead and Tin
Foil, applicable for Wrappers for Tobacco and all other suitable
purposes.
We EDWARD COPE GEM of the Firm of George Johnson & Company of
Montgomery Street Sparkbrook Birmingham in the County of Warwick Metal
Roller and Manufacturer and FREDERICK WILSON TAYLOR of the same place
Clerk to said firm do hereby declare the nature of this invention to be as
follows:-
Our invention relates to an improved method of manufacturing and finishing
lead and tin foil for various purposes and the process of manufacture is thus.
The lead and tin foil (or amalgamation of each metal) is first of all reduced
from the ingot by passing the same through rolls as in the ordinary manner until
the finishing stage is reached wherein our improvements come into effect by passing
both the roll and inctal foil during the final stage through hot water or solution
and also by burnishing the roll with eucalyptus oil or any suitable oil or other
product completing the process by stove drying.
The effect of this final treatment of the foil and also the preparation of the roll
is that a much brighter and more attractive appearance is given to the metal foil
than has hitherto been possible by the other and usual methods of manufacture.
Dated this 17th day of October A.D. 1892.

COMPLETE SPECIFICATION.
Improvements in and relating to the Manufacture of Lead and Tin
Foil, applicable for Wrappers for Tobacco and all other suitable
purposes.
We EDWARD COPE GEM of the Firm of George Johnson and Company of
Montgomery Street, Sparkbrook, Birmingham in the County of Warwick, Metal
Roller and Manufacturer and FREDERICK WILSON TAYLOR of the same place,
Clerk to the said firm 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 :-
Our invention relates to a method or process for the manufacture of lead and
tin foil and other like substance used for tobacco and various purposes generally.
The object of our said invention is to provide improved means for manufacturing
and finishing the lead and tin foil and we carry out our said invention in the
following manner :-
The lead and tin foil or amalgamation of each metal or such like substance or
metal or the amalgamation of metals of any suitable kind for our purpose, is first
of all reduced from the ingot by passing the same through rolls as in the ordinary
method of manufacture.
To imprint the pattern upon the metal foil it is passed between rolls, the top one
being of steel and having the required pattern thereon, the surface of the lower
roll consists of india rubber.
Reference to the accompanying drawing will assist in explaining our process.
The metal foil having been rolled down to the desired thickness is passed
between the rolls A. B. to imprint the pattern thereon.”

page_text: Below the rolls A. B. which are supported by bearings and standards C. in the
usual manner is situated a receptacle or pan D (carried by the standards or
otherwise), containing soap and hot water or other suitable solution, the lower
roll B. revolves in the solution in the receptacle or pan D.
In order to thoroughly cleanse the top roll A from dirt etc. we burnish the
said roll when required, previous to working with eucalyptus oil, or any suitable
oil, or other product, that may produce the desired effect, this latter operation being
performed by rubbing the roll over with the oil, which is for the purpose of
removing any dirt etc. that may be liable to get into the interstices forming the
pattern upon the roll.
When in motion the revolution of the lower roll B. within the receptacle or
pan D containing the solution causes the same to be thrown up onto the metal foil,
passing through the rolls, and also onto the top roll A, and cleanses the same,
moreover the steam arising from the hot water solution or other solution assists
to cleanse both the lower roll B, the metal foil, and the top roll A, from all dirt,
and impurities, the latter roll being also cleansed from the burnishing oil. The
process is then completed if necessary by stove drying.
The result of this treatment of the rolls and the metal foil is that a much
brighter and more attractive appearance is given to the metal foil (than has
hitherto been possible by the other and usual methods adopted in the manufacture
of the same) by reason of the fact of the rolls and foil being kept clean by our
process, this being of great importance to produce the effect.
We do not confine ourselves to the precise method herein set forth, as we may
deem it expedient to somewhat vary the same as occasion may require, without
any departure materially from the process of manufacture.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
Firstly. In the manufacture of lead and tin foil and other like substance, the
method of cleansing the rolls and also the metal foil with soap and hot water or
with solution of any suitable kind and by means of the steam arising therefrom
substantially for the purpose as herein set forth.
Secondly. In the manufacture of lead and tin foil and other like substance the
method of burnishing the said metal roll with eucalyptus oil or other suitable oil
or other product substantially as herein set forth.
Thirdly. In the manufacture of lead and tin foil and other like substance, the
combination of the process of cleansing the rolls and the metal foil with soap and
hot water or solution of any suitable kind and by means of the steam arising
therefrom and the process of burnishing the said metal roll with oil or other
suitable product in manner substantially as herein set forth.
Dated this 18th day of July 1893.
