Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I WILLIAM ALBERT JOHNS of Clapton, London in the County of Middlesex
Tin Plate Manufacturer do hereby declare the nature of my invention for
"IMPROVEMENTS IN TINNING AND WASHING TIN AND TERNE PLATES" to be as
follows:-
To accomplish the object of my invention I employ a tinning Bath nearly
S-shaped which is enclosed from end to end with the exception of a narrow opening
at is delivering neck. In this Bath is fixed a series of guides which extends from
end to end of the same. I leave at the entering end a hopper-shaped box containing
the coating composition A number of plates are then dropped into the same
grooved guide, and pushed forward together by a rod or hook worked either by
hand or machinery through the molten metal until opposite the opening at the
delivering end of the Bath; they are then pushed singly into a pair of rollers which
feed them downward 'between a pair of Brushes thereby cleansing them from all
the scruff and impurities which are liable to remain on the plates, they are
afterwards picked up between two pair of finishing rollers.
I so arrange the said Bath that a double quantity of plates can be tinned sufficient
to supply two or more grease and finishing apparatus and it can be employed in
combination with the grease Bath and Machinery which are at present in use,
disposing of the tinning, washing, and soaking Bath hitherto so indispensable.
Though Grease may be used I recommend for coating Ammonia prepared by
being melted on a higher temperature than the Tin or Terne metal until it gets into
a thick liquid.
I may mention that the machine has two side frames and five rollers--three on
the bottom abreast and two above with adjustable springs as is well understood by
practical men in the trade.

Middlesex Tin Plate Manufacturer do hereby declare the nature of my invention
for IMPROVEMENTS IN TINNING AND WASHING 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 :—
The object of this invention is to provide means whereby black plates or sheets
can be passed and guided through a Bath of coating metal without the necessity of
entering into guides where they have to cross each other has hitherto been requisite
in coating and finishing in one bath 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 drawing. Fig: 1 Is a sectional elevation of my
improved Bath Apparatus-Figure 2 is a plan of the same-A is a hopper shaped
box containing the coating composition of Ammonia being prepared by being melted
on a higher temperature than the Tin or Terne-metal. B. are rollers for feeding the
plates into and through the composition of Ammonia. C is a well or a pocket
where a number of plates are ready for the workmen to drop into the finishing
grease bath. D is a partition for separating the scruffy end of the Tinning bath
from the delivery end E are Guide bars for guiding the plates into the finishing
rollers F is a Grease Bath-G is the bottom of the Grease Bath HHHHare
the finishing rollers by which the plates are finished. I. I. are a pair of brushes for
cleaning the scruff off the plates as they enter the finishing Grease bath.
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 A bath which contains a Hopper shaped Box which contains a composition
of Ammonia prepared as herein before described.
2nd Composition of Ammonia prepared as herein described.
3rd Well or Pocket C substantially as herein described and illustrated in my
drawings.
4th A pair of brushes i. i as herein described and illustrated by my drawings.
5th A pair of Guides through which the plates pass from end to end of the
tinning bath as herein described and illustrated by my drawing.
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.
