I THOMAS HENRY JOHNS of 17 Gracechurch Street City of London in the
County of Middlesex, Gentleman do hereby declare the nature of this invention
to be as follows:-
I construct a suitable formed chamber through which the Plates pass from end to
end, the aforesaid chamber contains a liquid that will dissolve the grease off the
Plates as they pass through, such as benzoline, naptha, or any other liquid that
will dissolve grease. At the delivery end of the aforesaid chamber I place one or
more pairs of rollers so arranged to operate on the surface of the Plates that the
liquid will be thoroughly wringed off Should the Plates not be complete at this
stage I arrange a suitable heating apparatus through which the Plates can be
passed by hand or mechanical contrivance.

I THOMAS HENRY JOHNS late of 17 Gracechurch Street City of London in the
County of Middlesex Gentleman now of. 13 Blackfriars Street Manchester, do
hereby declare the nature of this invention for IMPROVEMENTS IN PROCESS AND
MACHINERY FOR CLEANING TIN AND TERNE PLATES and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:
In carrying out the invention I provide a suitable chamber which may with
advantage be made in the form of a balf or part circular bath chamber somewhat
resembling an ordinary grindstone trough in which is placed a liquid prepared and
suited for dissolving or decomposing or removing the grease remaining on the plates
as a result of the tinning process to which the plates are submitted in the ordinary
way or any equivalent way.
The known solvents of grease or oily or fatty matters may be employed.
I have found that benzoline, naptha or, methylated spirits or like solvents may
be advantageously used but equivalent solvents may as is obvious be substituted if
it be found advisable for economical or other reasons so to do.
The plates with the grease adhering to them are caused to pass through the
liquid solvent. and are subsequently treated in a manner which will be better
understood by reference to drawings as will also the machinery and movements of
the process.
"1
I have therefore prepared such drawings as I think calculated to aid in the
structure of the machinery and the practical carrying out of the process which
will be found on the following pages.
I make reference to the same thus :-
A: Is a bath.or chamber which contains methylated spirits, naptha, benzoline
or liquid solvent of an equivalent character or nature.
B. Is a main shaft carrying revolving arms which move and carry the plates
into, through and out of the liquid in the chamber.
C. Is a box into which the plates are placed in a liquid similar in nature to those
named above so as to prepare them for the speedier action of the liquids in the
chamber A.
.
D. Is a self acting plate feeder which delivers in regular succession the plates
after being treated in the grease pot in the ordinary or any equivalent manner to
the revolving arms to be caught and carried by them through the bath of liquid
solvent.
E: Are rollers of composition or similar substance resembling ordinary wringing
rollers, they are arranged and actuated so as to receive the plates one by one on
their emerging from the bath of liquid solvent for the double purpose of wiping
or pressing the moisture from their surface and for passing them forward and
delivering them upon endless travelling bands G. G. which carry the plates between
the surfaces of a heated chamber I I resting on brackets F F. In passing through
the chamber the plates are dried and delivered ready to be sorted for the market.

page_text: In order that the operations and matters may be still more readily understood
I further describe the same as follows viz:-The plates after having been treated
in the grease pot in the ordinary or any equivalent way are placed in the box C
from whence they are taken by an attendant and placed singly upon the self feeding
table D. They are then received and taken through the bath by the arms B;
thereafter they are seized by the wiping and cleaning rollers E and carried on the
endless bands G. G. through the heated chamber and thence delivering them ready
for sorting.
Having thus particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I do not restrict myself to the
precise details which as will be obvious to practical men are easy of variation
without affecting their main features; therefore what I claim is:-
1. The manufacture of Tin and Terne plates by treating them after they have
submitted to the ordinary preliminary processes and passed through the grease pot
in the ordinary or any equivalent manner in a bath of liquid solvent substantially
as described.
2. In the manufacture of Tin and Terne plates the use of a liquid solvent for
the purpose of removing the grease adhering to their surface as a result of the
ordinary process of their manufacture or any equivalent process substantially as
described.
3. The employment of a chamber for the treatment of plates by liquid solvents
substantially as herein described.
4. The combination of parts forming my improved apparatus for treating plates-
and carrying out the process of grease decomposition and plate cleaning, wiping,
travelling and drying substantially as herein described and illustrated by the
annexed drawings.
