which allows the other set to be drawn away and an opening left to allow of the plate
rising up between them. At other times the arms are pressed together by their own
weight or by counterbalance weights carried from their axes.

between arms and carried by them from one pot to the other they might be allowed to
rise up between fixed guides or arms and their lower ends be brought above lifters
levers or fingers carried by a horizontal rock shaft and the lifters levers or fingers then
by a half turn or any required motion of this shaft caused to carry the lower end of
the plate over or above the second pot and allow the plate to slide off and descend into
this pot. This may be effected by mounting a horizontal axis above the abutting ends
of the two pots and having lifters levers or fingers extending from it which when the
axis is turned into one position lie within grooves formed around one of the rolls of
the upper pair of withdrawing rolls of the first pot and by making this roll also with
longitudinal grooves or corrugations so that when the bottom of the plate has been
carried above the nip of the rolls the longitudinal grooves in the roll shall cause the
bottom of the plate to be carried over from the one side of the roll to the other and
deposit it on to the tops of the lifters levers or fingers-then by giving a half turn or
any requird motion to the axis which carries the lifters levers or fingers, the lower end
of the plate may be carried over and brought above the second pot and be then allowed
to slide off the lifters levers or fingers and drop into this second pot.

Improvements in Apparatus for Coating Metal Plates with Tin or
other Metal.
We, DANIEL EDWARDS, Tinplate Manufacturer, RICHARD LEWIS, Foreman,
PHILIP JONES, Mechanic, all of the Dyffryn Iron & Tinplate Works,. Morriston,
Swansea, 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 :-
In the Specification of a former Patent granted to us No. 5702 in the year 1885
we described means whereby with a "tinning" pot or bath of suitable dimentions we
were able to allow each plate which was to be coated to dwell for a time in the melted
coating metal and yet to carry on the coating continuously and uniformly.
We also described using with such apparatus a "dipping" pot containing finishing
coating metal the plates being introduced into such "dipping" pot by band after
coming from the "tinning" pot.
In the Specification of a subsequent Patent granted to us No. 7139 in the year 1887
we described a way in which the plates as they emerged from the tinning might be
guided downwards into the dipping pot. The way described in the Specification of
that Patent is well adapted for coating thin plates.
The object of our present invention is to facilitate the passing of thicker plates from
the first or "tinning" pot to the second or "dipping" pot.
For this purpose we cause each plate as it is raised by withdrawing rolls from the
first pot to pass up between arms which are suspended from axes at their upper end.
At the time the plate is rising up between the hanging arms one arm or set of arms is
held away from the other by manual or other means and when the plate has passed
the nip of the rolls the set of arms which are under control by the aforesaid means
are pressed against the plate and force the plate against the other set of arms so that the
plate gets nipped between them and being continued to be pushed the arms are rocked
into a position to carry the lower end of the plate above the second pot the arms are
then made to separate and allow the plate to drop down to the rolls in this second pot.
Afterwards the bar or handle by which the arms were previously pressed forward is
drawn back and allows the arms to swing over into position for another plate to rise
up between them from the first vessel-one set of arms then comes against a stop
which allows the other set to be drawn away and an opening left to allow of the plate
rising up between then. At other times the arms are pressed together by their own
weight or by counterbalance weights carried from their axes.
Figure 1 of the drawings annexed is a vertical section of apparatus arranged as
above described. A is the upper part of a tinning pot and B the upper part of a
dipping pot. CC are the uppermost pair of the rollers through which the plates are

page_text: drawn upwards from the tinning pot and DD the rollers to which the plates are
passed in the dipping pot. E F are arms carried at their upper ends by axes E' F'.
F2 is a weight on an arm projecting from the axis F by which the arms F
are pressed towards the arins E-the plates G as they rise up from the
tinning pot pass between these arms. The arms E can be pressed by the work-
man towards the arms F by a rod which passes from an arin on the axis E¹ to
the front end of the tinning pot. When the arms E are drawn back by the workman
into the position shewn in the drawing the arms Fare held away from them by an
arm on the axis F' coming against a fixed stop H as shown. A space is thereby
left between the arms up through which the plates can rise freely from the tinning
pot.
When a plate G has risen up between the arms as shown by the drawing, the
workman presses the arms E towards the arms F thereby moving the lower end of
the plate towards the arms E and then nipping the plate between the arms and
carrying it between them until the lower end of the plate is brought into position for
the plate to be dropped into the dipping pot, the arms F are then caused to move away
from the arma E by a pin I on the upper end of the arm F coming to the end of a slot
in the link J which is jointed to the upper end of the arm E at a greater distance
above the axis E' than the pin I is above the axis F¹.
In place of the plates when they have risen up from the first pot being nipped
between arms and carried by them from one pot to the other they might be allowed to
rise up between fixed guides or arms and their lower ends be brought above lifters
levers or fingers carried by a horizontal rock shaft and the lifters levers or fingers
then by a half turn or any required motion of this shaft caused to carry the lower end
of the plate over or above the second pot and allow the plate to slide off and descend
into this pot. This may be effected by mounting a horizontal axis above the abutting
ends of the two pots and having lifters levers or fingers extending from it which when
tho axis is turned into one position lie within grooves formed around one of the rolls
of the upper pair of withdrawing rolls of the first pot and by making this roll also
with longitudinal grooves or corrugations so that when the bottom of the plate has
been carried above the nip of the rolls the longitudinal grooves in the roll shall cause
the bottom of the plate to be carried over from the one side of the roll to the other and
deposit it on to the tops of the lifters levers or fingers-then by giving a half turn or
any required motion to the axis which carries the lifters levers or fingers, the
lower end of the plate may be carried over and brought above the second pot
and be then allowed to slide off the lifters levers or fingers and drop into this
second pot.
Figure 2 of the drawings annexed is a vertical section of apparatus constructed
in the above manner. A is the tinning pot, B the dipping pot CC the rolls by
which plates are lifted up from the tinning pot. E and F are fixed arms between
which the plates rise. K is a rock shaft mounted above the edges of the two
pots where they meet together. On it are fingers K-when the shaft is in the
position shewn in the drawing the ends of these fingers pass into grooves formed
around the roller C which is next to them-longitudinal grooves are also formed
in this roller as shewn more clearly on a larger scale at Figures 3 and 4.
Preferably the central part of this roll is of slightly less diameter than the ends
of the roll so that the plates are only nipped at their edges between the rolls CC¹
and the central part of the plate is not liable to be marked by the grooves in the
roll C.
When a plate has been drawn up from the tinning pot by the rolls CC the
lower edge of the plate drops into one or other of the longitudinal grooves in the
roll C and as the roll revolves it carries the bottom edge of the plate on to
the top of the fingers K¹. The workman then gives a half turn or thereabouts.
to this shaft K and thereby causes the fingers to carry the bottom edge of the
plate over the tinning pot and the plate slides off the fingers into the pot.
The workman then rocks back the fingers to their former position to bring them
into position for receiving another plate from the tinning pot.

page_text: 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:
-
1. The arrangement of mechanism substantially as herein before described with
reference to figure 1 for transferring plates from a tinning to a dipping pot.
2. The arrangement of mechanism substantially as herein before described with
reference to figures 2, 3 and 4 for transferring plates from a tinning to a dipping
pot.
