page_text: I WILLIAM ALBERT JOHNS of Clapton, London in the County of Middlesex, Tin
Plate Manufacturer do hereby declare the nature of my invention for "IMPROVE-
MENTS IN THE COATING AND FINISHING OF TIN PLATES AND IN THE APPLIANCES
USED THEREFOR to be as follows:-
"
To carry this invention into practice which has for its object improvements in
the manufacture of Tin and Terne Plates and in the appliances used therefor, and
is more particularly applicable to coating sheets or plates of Steel, Iron or other
metal with tin or terne metals or alloys whereby the same will be coated and
finished in one Bath. I employ a single Bath which contains the molten metal
requisite for the coating of the plates, as also the grease and apparatus through
which the plates are finished. This Bath is heated at the side containing the metal
and that portion containing the grease is heated from underneath so that I am
thereby enabled to procure a higher temperature for the coating and a lower one
for the finishing which is absolutely necessary in the manufacture of tin plates.
In the aforesaid Bath I provide two partitions and lifting apparatus, one of which
partitions extends upwards to the bottoin of the frame which carries six or more
finishing rollers and scruff wipers, and the second extends downwards below the
frame and the surface of the metal. The object of the former is to separate the
coating metal from the grease and machine by which the plates are finished, and
that of the latter to prevent the grease which is used for coating and the scruff
which necessarily accumulates on the surface of the molten metal from spreading
over that portion of the metal where the plates are delivered previous to their
entering the finishing portion of the Bath.
The advantage in my improved Metal Bath and apparatus is that I am enabled
to coat and finish in one Bath, plates with ordinary Palm oil or any other fatted
matter at the same time dispensing altogether with the washman's Brush, which
has hitherto not been accomplished without the aid of acids which are most
injurious to the iron.
In some instances I may mention that I provide a series of slotted guides at the
entering end of the Bath so arranged that a number of plates can enter therein,
being placed either straight or crossways, and they may remain soaking in the
molten metal; they are then pushed over by a curved lever to the other side of
the partition and raised up singly or in quantity into the finishing portion of the
grease Bath.

page_text: I, WILLIAM ALBERT JOHNS of 22 Rushmore Road Clapton in the County of
Middlesex Tin plate Manufacturer do hereby declare the nature of my invention
for IMPROVEMENTS IN THE COATING AND FINISHING OF TIN PLATES AND IN THE
APPLIANCES USED THEREFOR and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
My said invention relates to a combination of Arrangements for coating Tin and
Terne plates and in order that my said invention may be fully understood I shall
proceed to describe the same and for that purpose shall refer to the several Figures
on the sheet of Drawings.
Figure 1 is a Sectional elevation of my improved Bath or Baths and Figure 2 is
a plan of the same A is the Tin and Grease Bath. B is a Box which extends
downwards into the Molten Tin for keeping the Grease or solution through which
the black plates enter into the Tin C is a frame which carries the rollers D. D. D. D..
and the driving Shaft as shewn in plan, Figure 2 E is a Guide Bar to guide the
plates into the Rollers D B.
In Figure 2 is a plan of the Box which contains the Grease or Solution on the
face of the Molten Tin. In order to more fully explain the mode of working the
Bath. F contains the Grease and Machine for finishing the plates.-Bath F contains
the Molten Tin by which the plates are coated.-The workman who attends to the
Tinning passes the black plates singly or in a quantity into and through the Grease
or Solution in the Box B.-they are then raised out of the Molten Metal and
dropped singly into the Bath F and raised along the Guides E into the roller
D. D. D. D. and are finished.-Having now particularly described and ascertained
the nature of my said Invention and in what manner the same is to be performed
I declare that what I claim is :-
1st Bath A with a central partition H as herein described and illustrated by my
drawing.
2nd Box B which contains the Solution as herein described and illustrated by my
drawings.
'In Witness whereof I the said William Albert Johns have hereunto set my hand
and seal this eighth day of October in the year of our Lord One thousand
eight hundred and eighty four.
