We, CHARLES MORRIS, and GEORGE BIRKBECK both of the Gower Iron and Tin
Plate Works Limited Penclawdd in the County of Glamorgan Tin Plate Manufacturers
do hereby declare the nature of this invention to be as follows:-
Several methods have lately been introduced in the manufacture of tin and terne
plates to avoid the costly "brushing process" by passing the plates or sheets to be
coated through a flux box and then through the coating pot by means of rollers or
other machinery and our invention has for its object to dispense with such rollers
or machinery in the coating of terne plates and also to effect considerable economy.
Now our improvements consisting in adapting a flux box made of sheet iron or
other suitable material to the ordinary "coating pots" (or if desired to other "pots
of various descriptions) or the flux box may be cast in one part with the pot.
"
This flux box is placed above the surface of the metal (and filled with flux or
grease which being lighter than the metal cannot escape) in such a position that the
metal sheets or plates may be readily passed through the flux or grease by means of
a hook or prong or other suitable holder and after having passed the bottom edge
of the flux box into the terne metal they come out ready coated with metal without
the aid of rollers or other machinery and in a convenient position for the worker
to hand them over to the finishing grease pot where they are finished in the ordinary
manner.
"
Sometimes a "dipping pot is used containing metal in which case the before
mentioned pot is made double-i.e. there is a division placed down the middle
thereof so that no connection takes place between the two compartments the plates
being first passed through the flux box as before described into the "coating" metal
and then taken out and dipped" in the next compartment containing the "clean
metal.
دو

page_text: The two divisions in the same "pot" being both heated by the same fire or furnace
and thus effecting an economy of fuel.
By this simple adaptation of the flux box as before described wo find that we can
work terne sheets or plates without using the brushing process and thereby save the
labour known as the "washman."

We CHARLES MORRIS and GEORGE BIRKBECK both of The Gower Iron and Tin
Plate Works Limited Penclawdd in the County of Glamorgan Tin Plate Manufacturers
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:-
Several methods have lately been introduced in the manufacture of tin and terne
plates to avoid the costly "brushing process" by passing the plates or sheets to be
coated through a flux box and then through the coating pot by means of rollers or
other machinery and our invention has mainly for its object to dispense with such
rollers or machinery in the coating of terne plates and also to effect considerable
economy.
Now our improvements consist in adapting a flux box made of cast iron or other
suitable material to the ordinary "coating pots" (or if desired to other pots of
various descriptions) or the flux box may be cast in one part with the pot.
This flux box is placed above the surface of the metal (and filled or partly filled
with flux or grease which being lighter than the metal cannot escape) in such a
position that the metal sheets or plates may be readily passed through the flux or
grease by means of a hook or prong or other suitable holder and after having passed
the bottom edge of the flux box into the terne metal they come out ready coated
with metal without the aid of rollers or other machinery and in a convenient position
for the worker to hand them over to the finishing grease pot where they are
"finished" in the ordinary or any suitable manner.

page_text: Sometimes a "dipping pot" is used containing metal in which case the before-
mentioned pot is made double i.e.-there is a division placed down the middle thereof
so that no connection takes place between the two compartments the plates being first
passed through the flux box as before described into the coating metal and then
taken out and "dipped" in the next compartment containing the "clean" metal.
The two divisions in the samo pot may be both heated by the same fire or furnace
and thus effecting an economy of fuel.
Or if desired the dipping pot when used may be mado separato from the coating
pot..
By this simple adaptation of the flux. box as before described, we find that we can
work terne sheets or plates without using the brushing process and thereby save the
labour known as the "washman " brushman."
وو
or
:
And in order that our invention may be the more easily understood and readily
carried into practice we will proceed to describe the same more fully with reference
to the accompanying drawings.
Figure 1 shows a view of the hook or prong for pushing the plates down through
the flux box into the terno metal.
Figure 2 shows a sectional side elevation of a terne "set" having our improvements
applied.
Figuro 3 shows a plan view of same.
Figure 4 shows a sectional side elevation of another arrangement.
Similar letters of reference indicate corresponding parts in all the Figures.
Referring to Figures 1 to 3 a is the flux box having lugs or cars a¹ cast or
mounted thereon through which it is bolted or secured to the top part of the pot b.
About the centre of each side of this pot beads or projections 6 aro cast or
mounted which serve as guides to hold and retain the division plate c which is placed
there (or this division plate c may be cast in with the pot b) to divide the pot 6 into
two compartments d and e; d being the "coating pot" above which is mounted
the flux box a, and e being the "dipping pot."
The material in the flux box a (advantageously flux) floats upon the surface of the
molten terne metal but cannot escape therefrom as the lower edges of the flux
box a project some distance below the surface of the molten terne metal 9 as shown
in Figure 2.
The operation is as follows:
The "black" plato to be coated is by means of a hook or prong such as that
shown in Figure pushed down edgoways through the flux box a until its upper
edge is below the lower edge a² (Figure 2) of the flux box a beneath the surface of
the molten metal g.
The plate is then pushed under the edge a² and released from the prong or 'hook
and it then rises by its own buoyancy and comes partly out of the metal g at d.
It is then lifted out and "dipped" in the next compartment f.o. in the dipping
pot e and afterwards "finished" in the "finishing grease pot" h in the ordinary or
any suitable way and thus dispensing with the operation known as brushing and
thereby effecting considerable economy.
In the modified arrangement Figure 4 the operation is identical the only difference
being that the coating pot d with flux box a mounted thereon is made separate from
the "dipping pot"-e as shown.
If desired the "dipping pot" e may be dispensed with and the plates after coming
out of the "coating pot" d may be finished at once in the "finishing grease pot" h
as is well understood.
We would remark that we do not confine ourselves to any particular materials
sizes or shapes in the construction of the apparatus to carry out our process as these
may vary within suitable limits.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what we
claim is :-
1. In the process of terning metal sheets or plates the use and application of a
flux box such as a mounted or arranged on or over the "coating pot" without the
use of any rolls or machinery in either and the lower edge of the flux box being
below the surface of the molten terne metal in the "coating pot" substantially as
and for the purposes herein before set forth.
2. In the manufacture of terne plates the improved process of passing the metal
sheets or plates to be coated through a flux box such as a mounted or arranged on
or over the coating pot d by hand by means of a suitable hook or prong the plates
on being released therefrom rising of themselves to the top of and partly out of the
molten terne metal outside of the flux box from whence they are lifted by manual
labour and "finished" without brushing in the ordinary or other suitable way either
with or without being "dipped" in the "dipping pot" all substantially as herein-
beforo described with reference to the accompanying drawings.
