Improvements in Pots or Machines for Tinning Metal Plates, and
for like purposes.
We, ERNEST TRUBSHAW, Tin Plate Manufacturer of Aelybryn, Llanelly, and
WILLIAM DUMMER, Tin House Superintendent of 13 Marsh Street, Llanelly,
both in the County of Carmarthen, do hereby declare the nature of this invention
to be as follows:-
Our invention has reference to the construction and arrangement of a machine or
are enabled to
apparatus for tinning or coating- metal plates, whereby we
automatically deliver the plates to the rollers while within the entering pot, and
thus to effectually cover the plate, and to produce a uniformity of coat in an
economical manner.
}
In carrying our invention into effect we arrange our improved machine, or
apparatus in combination with the ordinary pot having the ordinary rolls arranged
within it and we place in connection with the same our entering pot which receives
the black plate from our improved carrier or slide. We cause the entering pot to
be shaped to suit the width or length of plate which is to be covered and we place'
within it a slide which has a ledge and hook upon it suitable for carrying the plate
nd for covering the upper edge of the plate when thus carried, and we cause this
slide to travel up and down within our entering pot in one convenient manner by
means of a crank shaft or crank disc which by its revolution draws up a chain and
drawing it up draws the slide up through the molten metal within the pot; we
prefer to make the slide and its attachments heavy enough to produce the downward
or return motion by its own weight and when it reaches the bottom of the entering
pot we cause it to rest upon the foot of a rocker which rocker has arms or'
knockers carried upon it so that the weight of the slide causes the knockers or
arms to throw off the plate from its upright position, and to cause it to fall in an
inclined position towards the outlet mouth of the entering pot. When the plate
has been thus inclined or thrown off the hooked fork into the outlet mouth the
upward movement of the slide carries the plate towards the rolls placed within the
pot and the rolls by suitable guides receive the plate and carry it through the pan;
and through the palm oil floating upon the surface of the tin so that it passes from
one pair of rolls and through other pairs of rolls oxidation being prevented as it'
travels through the oil and thoroughly tinned before it leaves the final pair of rolls
at the upper end of the pot. Within our eutering pot we arrange the guides:
suitable for the slide with its hooked fork to travel up and down in, and we make
the framework within the pot suitable for the guiding plate when it has been
drawn over from off the fork by the rocker placing suitable baffle plates or striking
plates within the pot to prevent the plate from being carried upwards when the
upward motion of the slide is being made.
We arrange two or more slides within the same pot to suit the number of sheets
that it is desired to coat in the same machine at the same operation, and-we
arrange..any number of pulleys with their connections similarly to the manner
herein before described to actuate the slides within the pot.
"
The arrangement of the oil and the tin within the roll pot and the guides for the
plate to be directed from one set of rolls to the other, we make in any usual well
known manner, and we employ any well-known flux to cover the surface of our tin'
3 or terne or other metal, within the entering pot for the plates to pass through.

page_text: We do not limit the application of our invention to any particular form or
shape of entering chamber and we combine the chamber with existing pots when
making the same to suit machines at present in use or we may construct the whole
combination in one piece of apparatus, being jointed and connected together in any
manner suitable for such purpose. Similarly we modify the method of raising and
lowering the slide to suit the machinery or power which is to be employed in
connection with the apparatus.

Improvements in Pots or Machines for Tinning Metal Plates, and
for like purposes..
We, ERNEST TRUBSHAW, of Aelybryn, Llanelly, Tin Plate Manufacturer, and
WILLIAM DUMMER, of 13 Marsh Street, Llanelly, Tin House Superintendent,
both in the County of Carmarthen, 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:-
Our invention has reference to the construction and arrangement of a machine
or apparatus for tinning or coating metal plates, whereby we are enabled to
automatically deliver the plates to the rollers while within the entering pot, and
thus to effectually cover the plate, and to produce a uniformity of coat in an.
economical manner.

Figure 1 is a sectional elevation of our improved pot and machine.
Figure 2 is a-plan. of same....
Figure 3 is a sectional end elevation one half being taken on the line X+X; the
other.half on the-line Y Y.
In carrying our invention into effect we arrange our improved machine, or
apparatus, in combination with the ordinary pot Ar having the ordinary ·
rolls B.B BB arranged within it and we place in connection with the same
our entering pot C which receives the black plate from our improved carrier or
slide D.G. We cause the entering pot to be shaped to suit the width or length of
plate which is to be. covered, and we place within it a slide Gwhich has a
ledge H and hook K. upon it suitable for carrying the plate F and for covering
the upper edge. of the plate when thus carried; we cause this slident travel up
and down within. our entering pot in one. convenient manner by means of a crank
shaft L Lor crank disc which by its revolution draws up a chain M M', and
drawing it up draws the. slide..up through the molten metal within the pot; we
prefer to make the slide G. and its attachments. heavy enough to produce the
downward or return-motion by its own weight and when it reaches the bottom of
the entering, pot.we cause it to rest upon the foot: N¹ of a rocker. N which rocker
has arms or knockers O carried upon it so that the weight. of the slide causes the
knockers or arms to throw off the plate F from its upright position and to cause it
to fall in an inclined position towards the outlet mouth C. of the entering pot C.
When the plate has been thus inclined or thrown off the hooked fork sinto the
outlet mouth the upward movement of the slide. carries the plate towards the
rolls P-placed within the pot, and the rolls by suitable guides Rareceive the plate
and carry it through the pan a and through the palm-oil floating upon the surface
of the tin so that it passes from one pair of rolls B and through other pairs of
rolls B.B' B, oxidation being prevented as it travels through the oil and becomes

bot. Within our entering pot we arrange the guides S S₁ suitable for the slide
with its hooked fork to travel up and down in, and we make the framework within
he pot suitable for guiding the plate when it has been drawn over from off the
fork by the rocker, placing suitable baffle plates T or striking plates within the
pot to prevent the plate from being carried upwards when the upward motion of
the slide is being made.
We arrange two or more slides D D' within the same pot to suit the number of
sheets that it is desired to coat in the same machine at the same operation, and we
arrange any number of pulleys U U¹ with their connections similarly to the
manner hereinbefore described to actuate the slides within the pot.
The arrangement of the oil and the tin within the roll pot and the guides for
the plate to be directed from one set of rolls to the other, we make in any usual
well known manner, and we employ any well known flux to cover the surface of
our tin or terne or other metal, within the entering pot for the plates to pass.
through.
We do not limit the application of our invention to any particular form or shape
of entering chamber, and we combine the chamber with existing pots when making
the same to suit machines at present in use, or we may construct the whole
combination in one piece of apparatus, being jointed and connected together in
any manner suitable for such purpose. Similarly we modify the method of raising
and lowering the slide to suit the machinery or power which is to be employed in
connection with the apparatus.
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 improvements in machines and apparatus for tinning or coating metal
plates substantially as and for the purposes hereinbefore described and as illustrated.
in the accompanying drawings.
2. In a tinning or metal coating machine the combination with an ordinary pot
having rolls within it of an entering or receiving pot into which the plate is first
introduced before it is transferred to the rolls in the ordinary pot substantially as
herein before described and as illustrated in the accompanying drawings.
3. In tinning or metal coating machines the combination and arrangement of a
5 sliding plate carrier with a rocking or moving bar or frame which alters the
position of the plate so that it may when lifted be directed towards the rolls
substantially as herein before described and as illustrated in the accompanying
drawings.
