IMPROVEMENTS IN COATING METALS
Year: 1859

page_text: LETTERS PATENT to Edmund Morewood, of Enfield, in the County of
Middlesex, for the Invention of "IMPROVEMENTS IN COATING METALS."
Sealed the 30th March 1860, and dated the 3rd October 1859..
PROVISIONAL SPECIFICATION left by the said Edmund Morewood, at
the Office of the Commissioners of Patents, with his Petition, on the
3rd October 1859.
I, EDMUND MOREWOOD, of Enfield, in the County of Middlesex, do hereby
declare the nature of the Invention for "IMPROVEMENTS, IN COATING METALS," to
be as follows:
. One part of my Invention consists in passing in a wet state, sheets, plates,
or pieces of coated or uncoated iron or copper (when to be coated with melted
tin or lead, or compounds thereof) into the flux contained in a suitable appa-
ratus, in contact with such melted metals and rising above them.
Sometimes in order to free plates or suitable pieces of metal coated with
lead or tin, or their alloys from the flux which adheres to them on emerging
from the melted coating metal, I immerse them a second time in melted
metal, which is covered either with no flux, or only with such a flux as does
not cling so much, or is more easily removed, or is otherwise less objectionable.
Another part of my Invention consists, in having a pair of rollers in front
outside the melted metal, to receive the plates or suitable pieces of iron or
copper either coated or uncoated, and by their revolution to introduce them
through the flux, or otherwise into the melted metal, and to assist in passing
them through such melted metal in order to give them a coating either in.
connection with a roller or rollers, or a guide or guides, or both under the

page_text: coating metal; such rollers with suitable arrangements at their ends and sides
may be made instrumental in confining the flux, and the smoke therefrom.
Again, in coating with rollers, I sometimes cause sheets, plates, or suitable
pieces of iron or copper, coated or uncoated, to have a considerable horizontal
or nearly horizontal travel under the surface of the melted zinc, tin, lead, or
their alloys, by placing one or more pair at such distances behind the first, as
to cause the sheets or pieces of metal passing between the rollers to travel the
required distance under the surface of the melted metal in a somewhat hori-
zontal direction.
I also find it important in many cases to use the rollers between which
the said coated or uncoated sheets or pieces of iron or copper pass under the
surface of the melted metal, completely submerged in the melted metal.
And to secure the regular travel of such plates, or pieces of iron or copper,
into the opening between the front rollers which are under the surface of the
melted metal, then from the front to the next pair, and so on through the rest
of their journey, when desirable I use guide pieces or bars of iron, or suitable
material.
And I make them so that that part or surface of the guide along which such
sheet or piece of iron or copper travels, shall present nothing against which
the plate or piece of metal may catch in its journey, or the guide pieces or
bars may be made to act as substitutes for a second or third pair of rollers.
Such guide pieces or bars are also of advantage with deep rollers, and some-
times they may be used without rollers at all. In coating some sheets and
pieces of iron or copper, especially small sized ones, I use an intermediate pair
of rollers between the last pair under the surface of the melted metal, and
the delivering rollers herein-after mentioned, in order to lessen the distances
between those two pairs, such intermediate pair work near the surface of the
melted metal on the exit side.
Another part of my Invention consists in having a pair of rollers so arranged
above the surface of the melted metal, that the sheets or suitable pieces of
iron or copper pass into the opening between them after emerging from the
melted metal, and are carried by their revolution out of the metal, and onward
in such a way that a workman can conveniently receive them. And I some-
times cause such rollers to stretch or draw the surface, and do other useful
work. These I call delivering rollers.
Further behind these rollers, I sometimes place a pair of polishing rollers,
or else I place such polishing rollers in such a position that sheets or pieces of
iron or copper when coated and dried, pass between them in order to obtain a
better surface.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edmund Morewood in the Great Seal Patent Office on the
3rd April 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDMUND
MOREWOOD, of Enfield, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of October, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Edmund Morewood Her special licence that I, the said Edmund
Morewood, my executors, administrators, and assigns, or such others as I, the
said Edmund Morewood, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN COATING METALS," upon the condition (amongst others)
that I, the said Edmund Morewood, my executors or administrators, by an
instrument in writing under my or their, or one of their hands and scals, should
particularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Edmund Morewood, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:―
In order to make iron or copper (either previously coated with other metal
or not) take a coating of melted lead or tin, or alloys of lead and tin. I have
found it important to pass the sheets, plates, or pieces of iron or copper in a
wet or damp state into the flux which is on the surface of the melted coating
metal, and which is contained in what is termed a flux box, or other suitable
apparatus, at the entrance side of the bath of melted coating metal. In
passing the sheets, plates, or pieces in a wet state into the flux, I use a deep
flux, say five or six inches, confined by a flux box, with sides rising eight or ten
inches above the surface of the melted metal. Along or around the inside and the
top of these sides I fasten what I term a cushion of woollen cloth, wool, or such
matter as will readily imbibe and retain a considerable quantity of liquid. The

page_text: workman has thus the opportunity if he finds a sheet or plate, or piece of iron
or copper too wet (and likely to cause an explosion if introduced into the flux
and melted metal) to pass it along or upon such cushions, and thus to remove
any superfluous moisture. The absorbing cushion, from the warmth of its
position above the surface of the melted metal, soon loses by evaporation the
moisture so transferred from the sheet or plate, or piece of iron or copper.
Or, I prefer to pass the sheets, plates, or pieces through the flux and into
the melted metal by a pair of outside front rollers as herein-after described,
and which I call receiving rollers. These I place in such a position on the
entrance side of the bath of melted metal that the opening between the rollers
through which the plates, or sheets, or pieces pass is above the surface of the
melted metal, and such rollers form a barrier between the hands and face of
the workman and any metal that may spurt up. Sometimes on withdrawing
the plates or sheets, or pieces of iron or copper from the melted lead or tin, or
their alloys, the plates, or sheets, or pieces will come out with more or less of
the flux still adhering to them. In order to free them from this adhering flux,
I immerse them a second time in melted metal, which is covered either with
no flux at all, or with only such a flux as is known not to cling, or is more
easily removed, or is otherwise less objectionable that that which adheres to
them in the first instance. Thus, if I cause the pieces, or sheets, or plates
of metal which are to be coated to pass into the melted tin, lead, or alloys
through waste or spent flux, as described in the Specification of my Patent of
the 4th April 1859, and on the withdrawal of the said iron or copper from
the melted coating metal so much of the waste flux clings to the surface that
I wish to remove it, I sometimes immerse it afresh into melted lead, tin, or
alloys, the surface of which I keep as free as I can from such waste or spent
flux by skimming off from time to time such as may be introduced by the
plates, sheets, or pieces. The metal into which the plates are thus immersed
the second time, may either be contained in a separate bath from that con-
taining the metal for the first immersion, or it may be contained in the same
bath, the surface of the melted metal for the second immersion being kept
separate from that for the first immersion by a partition, which I make of iron.
If coating with lead alone, I sometimes use sal ammoniac on the surface of
the melted metal contained in the second bath, or on that part of the melted
metal into which the second dipping of the plates, sheets, or pieces takes place.
But I prefer to keep it as free as I can from any flux.
A third part of my Invention consists in having a pair of outside rollers on
the entrance side of the melted metal, which I call the receiving rollers. One
object I have in view in using these receiving rollers is, that being themselves

page_text: warm from their position, or having warmth communicated to them by being
nade hollow, and by the introduction of steam into such hollow, as is well
understood, they give warmth to the sheet, or plate, or piece of iron or copper
as it passes between them before entering into the melted metal; and thus
essen the chilling effect of the introduction of cold or damp sheets into the
melted metal. Further, such rollers lessen, if they do not altogether prevent,
the risk of injury to the workman putting in damp sheets, or plates, or pieces.
And, also, when a flux is on the surface of the melted metal and immediately
below the rollers, they hinder the escape of the vapour of the flux. I prefer
to place them nearly horizontally in a frame as shewn in the annexed
Drawing, so as to receive between their openings the plates, or sheets, or pieces
of iron or copper, either coated or uncoated, before they enter either the flux
or the melted coating metal. And by the revolution of these receiving rollers,
such sheets, or plates, or pieces of iron or copper to be coated are introduced
into the melted metal, either through a flux or not. And further, by their
continued revolution they assist in passing such sheets or suitable pieces of
iron or copper through such melted metal until they reach another revolving
roller or rollers either under or outside of the coating metal. But I prefer to
use these front outside rollers in combination with rollers and guides as shewn
in the Drawing hereunto annexed, which shews a section of apparatus
combined according to my present Invention. A; A, are the pair of front out-
side rollers. I prefer to place these front outside rollers in such a position
that they form the roof of a space over the entrance side of the melted metal.
Under such roof and on the surface of the melted metal I prefer to place the
flux, the surface of the melted metal being about four or five inches below the
under side of this pair of front rollers. And I prefer further, to confine
the space and exclude the air as much as possible between such rollers and
the melted metal by a piece of iron stretching along on every side except in
front, where I make a door sufficiently large to enable me to introduce new
flux as required and to clear off the dirt or spoiled flux, and thus such iron
inclosure forms a wall between the outside of such pair of front rollers and
the surface of the melted coating metal, such wall dipping slightly below the
surface of such coating metal. I have the roller nearest to the entrance side
of the bath of melted metal slightly lower (say to one inch, if the rollers be
four inch diameter) than the other, so as to give the sheet or plate a slightly
forward inclination towards the rollers in the melted metal as it passes through
such outside pair of front rollers.
I also consider it desirable sometimes to increase the length of time.during
which the sheets or suitable pieces of iron or copper, coated or uncoated, are

page_text: submerged in the melted coating metal, by causing them to have a consi-
derable horizontal, or nearly horizontal travel under the surface of the melted
zinc, tin, or lead or their alloys. This I prefer to do by so constructing the
frame of the rollers as to have one or more than one pair revolving at such
distance behind the first pair under the surface of the melted metal that the
sheets or suitable pieces of iron or copper, coated or uncoated, shall be passed
along by the revolution of the first pair in a horizontal, or nearly horizontal
direction to the succeeding pair, and by their revolution either upwards and
out of the melted metal or still, or in a more or less horizontal direction to
and between other rollers under the surface of the melted metal. In such
case I place the last pair of rollers working in the melted metal one or two
inches nearer to the surface of the melted metal than the preceding pair;
and instead of placing the lower roller of such last pair directly below the
upper roller, I place it (if the diameter of such roller be 4 inches or there-
abouts) about one inch nearer the exit side of the bath containing the melted
metal. And where two or more pair of rollers are used in the melted metal,
I place the lower roller of the front pair in the metal about an inch nearer to
the entrance side of the bath than the upper roller instead of the former
directly below the latter.
In order to cause the pieces of metal to travel with certainty in the required
direction from roller to roller, I use guides, or guide pieces made of iron, as
hereinafter described. I also prefer to have the rollers between which the
pieces, sheets, or plates of iron or copper to be coated travel under the surface
of the melted coating metal completely immersed, as should any portion of
such revolving roller be above the surface of the melted metal, it is apt, in
revolving, to catch or draw down flux or dirt from the surface of such melted
metal. Again, in order to ensure the travel of the sheets, or plates, or pieces
of iron or copper in the direction I desire, first between the outside front
rollers, thence under the surface of the melted zinc, tin, or lead, or alloys
thereof, I use guide pieces or bars of iron, the first of which may (being out of
the melted metal) be simply boards of wood laid nearly horizontally, but with
a slight slope down to the front outside rollers, and so placed as to conduct
such suitable pieces of coated or uncoated iron or copper, first to the outside
front rollers, then by guides of iron I conduct the iron or copper to be coated
into the melted coating metal, and onward to the opening between the front
pair of rollers under the surface of the melted metal. I make this, which I
call the second front guide, which is marked in the Drawing A³, of a piece of
wrought iron, about ths inch thick, in width equal to the length of such
immersed front rollers, which are marked in the Drawing B, B, between their

page_text: axles, and in depth stretching from a point about four inches above the
surface of the melted metal on the entrance side of the bath to such a point
below the surface, that the lower edge of such guide plate lays along the
upper part of the lower front roller working in the melted metal close to the
opening between the pair. I rest the upper part of this second front guide
plate against the flange on the entrance side of the bath of melted metal, to
which I attach it by screws or other fastenings, and it lays in such a direction,
that sheets or suitable pieces of metal passing down and along it, are by it
conducted to the opening between the front pair of rollers under the melted
metal. Sometimes I connect this guide piece to a plate of iron of cor-
responding length resting upon the upper front roller (immersed partially or
wholly in the melted metal,) and rising from such upper front roller to the
surface of such metal. And in such case I prefer to continue this guide
several inches above the surface of the melted metal, so as to form a very
deep flux box, as marked A' in the Drawing, as well as a front guide.
If I work with two or more pair of rollers partially or wholly under the
surface of the melted metal, I use what I call a middle guide, which is marked
in the Drawing B', to conduct the sheets from the first immersed pair to the
next. This middle guide consists of two long plates of wrought iron th inch
thick, so connected together by a bolt, strap, or piece of iron at each end, that
they are nearly horizontal and almost parallel one above the other between
the first and second pair of rollers under the melted metal. The sides of such
guide are open; that which rests against the exit side of the rollers, and at
which the plates enter on leaving the front rollers which work in the melted
metal being about an inch and a half apart, and about of an inch apart
where the sheet leaves such middle guide to enter the opening of the suc-
ceeding pair of the immersed rollers. The sheet, plate, or suitable piece of
iron or copper to be coated thus travels from one pair of rollers to the other
between these plates, and within a space so confined and tending in such
direction as to cause the plate, sheet, or piece of metal to travel from the first
immersed pair of rollers into the opening between the succeeding pair of
rollers which are marked in the Drawing C, C. The length of this guide
piece is equal to that of the rollers between their axles and the width, such as
to reach over the distance between the back of the front pair of rollers, which
work in the melted metal to such point at the opening between the second
immersed or partially immersed pair, as will insure the plates or sheets, or
pieces entering them. These guide plates are fixed in their place by the ends
being fastened by a screw or bolt into the frame of the rollers. Such guide
plates have round holes about an inch in diameter and one inch apart running

page_text: the whole length of the plate, the object of such holes being to permit the
escape more freely of any dross or dirt or foreign matter in the melted metal
or upon the plate. Between these spaces I make the thickness of this guide
plate about of an inch stouter than in other parts, making it project inwards
to that extent in a slightly sloped or arched form so as to cause the sheet,
plate, or piece travelling through the guide to rise somewhat (when passing
these holes) from the level of the other parts of the guide plates, and thus
avoid the risk of the corners of such travelling sheet or plate, or piece catching
in the round holes of the guide plates; and I give the projecting thickness of
metal such a sloping or arched rise as will prevent such projection from
stopping the sheet in its travel through such middle guide.
In order to conduct the plates or sheets or pieces in the required direction
from the last pair of rollers, which work in the melted metal, I use what I
term the back guide, which is marked in the Drawing C' and which conducts
the sheet or plate or suitable piece of iron or copper to be coated from the
back rollers working in the melted metal either to rollers outside of the melted
metal, or to such other point as may be desired. I made this back guide in
the following manner :-I take a plate of iron about an inch thick (or in case
the melted metal be zinc, then two inches thick), and five inches wide, of the
same length as the back rollers in the melted metal between the axles. This
plate I form with such a lateral curve that when it is in its place along and
against the lower back roller, it may allow the sheet or plate or piece of iron
or copper when making its exit from these back rollers to take such a sweep
as may be desirable before or in making its ascent through and from the
melted metal. To this curved piece of iron I fasten bars of half round iron
about an inch thick in such manner that when the curved plate is in its place
upon the back roller the bars shall stretch upwards toward, or to, or beyond
the surface of the melted metal, and present their rounded side to the sheet
or plate which is making its exit from the back rollers, and combine with
the curved plate and other parts of the back guide, to prevent the sheet
or plate travelling otherwise than in the desired direction out of the melted
metal; I strengthen and further connect these half round bars by flat bars of
iron about two inches wide and one inch thick, crossing such bars of half round
iron at right angles, and being about seven inches apart; and I fasten these
flat cross bars to the flat side of the half round iron. I then take another plate
of iron also about an inch thick, and about two or three inches wide, in length
the same as the upper back roller, working in the melted metal between its
axles, and fasten to it also half round bars of iron about an inch thick, and
also strengthened by flat bars fastened across the flat side of the half round

page_text: iron at right angles. When this plate with the bars attached to it is in its
place the lower edge of the plate rests along the upper back roller. And the
half round bars rise from it upwards towards the surface of the melted metal,
or to or beyond it, and in such a direction that when this upper roller plate
with its cross bars or grating is fastened by a bolt or other connection at each
end to the bars or grating of the before-described lower roller plate they form
together a back roller guide, open to the extent of two or three inches at the
point at which the sheet or plate which is travelling through the melted metal
enters between it from the immersed or partially immersed back rollers. The
two parts of this back guide are so connected that the rounded part of all the
half round bars is always presented to the sheet or piece of iron or copper to
be coated when travelling along or up between it. And the bars of this guide
are made of such length as may be found most convenient. They are also
made either to rise upright from the plate sitting against the back rollers in
the melted metal, or to take such a slope or curve as may be preferred, in
order to guide the sheet or plate, or suitable piece of iron or copper to be
coated when travelling between them to the surface of the melted metal or
beyond it in the most desirable direction. As a rule, I prefer to place the
back guide or the back rollers and guide so as to cause the sheet to rise out of
the melted metal as nearly upright as possible. In some cases when this back
guide extends out of and beyond the surface of the melted metal, the sheet or
plate or suitable piece of iron or copper to be coated is liable to be somewhat
scratched or marked in consequence of its surface, whilst the coating is still
soft and warm, touching and rubbing against the half round bars of the guide,
which confine such travelling sheet or plate, and give it the proper direction.
In order more completely to avoid this marking or scratching I attach a rod
of iron about th inch diameter from end to end on the outside of this back
guide. Before fixing it in its place I put it through the hollow of iron rollers,
whose length is such as to allow them when in their position to revolve
between the half round bars of the guide, and also to enable me to introduce
oil for cleaning the rod from time to time. The diameter of these hollow
rollers is about three inches. They have a round hole about one inch through
them, so as to admit of their revolving freely when upon the inch rod.
Before fastening the rod in its place to the back rollers I put it through the
hollow of these three-inch rollers, and then fix the rod from end to end of the
back guide in such a position that the hollowed rollers shall lie horizontally
between the upright half round bars of the back rollers, and project to the
extent of a quarter or half an inch beyond them on the rounded side, up
which the sheet or plate or suitable piece of iron or copper travels, and so

page_text: place them that the surface of the sheet after emerging from the melted metal
shall come upon such roller before, and instead of scratching or rubbing
against the bars and continue its travel kept off the bar by such projecting
roller, to which, by its travel, it communicates a revolving motion; this guide
roller is marked in the Drawing D'. The rod and the hollow of the rollers
should be kept clean, so that the rollers may revolve freely; or such roller
may be fastened to its axle, and have the desired speed given to it by a wheel
geared to one of the other moving wheels of the machine; and such roller
may be placed on a level with or slightly higher than the delivery rollers, and
so as to cause the sheet to take a curve or'bend before falling upon the outside
delivering or back rollers, so as to straighten and stretch it.
When I use only one pair of rollers working in the melted metal, I omit
the middle guide, and cause the sheets to enter the back guide immediately
on leaving such single pair, which work in the melted metal. In such case I
sometimes so shape the back guide that the sheets or plates shall take a sweep
in a horizontal or nearly horizontal direction under the melted metal after
leaving such rollers, and before they rise out of the melted metal. Sometimes
I leave out the rollers in the molten metal altogether, in which case the front
receiving rollers introduce the sheets or plates into the guide in the melted
metal, and by their revolution send it forward through the melted metal and
between the guides, until by travelling along them it reaches the exit surface
and passes out and into the outside delivering rollers. In such case I make
the travel of the sheet or plate to be in a nearly horizontal direction through
the melted metal.
In some cases (especially when coating small-sized sheets or plates of iron
or copper) I find it advantageous to use an additional pair of rollers outside
the metal, but on the exit side of the bath. These rollers I place so near to
the surface of the melted metal on the exit side of the bath, that they support
the plate or sheet over the space between the rollers working in the metal and
the delivery rollers, herein-after mentioned, so that the sheet or plate has not
so long an unassisted travel between the back guide, as it otherwise would
have to the delivery rollers. In coating small plates of the size of tin plates
this distance would sometimes be too great to allow the plate to enter the
rollers, herein after mentioned (and which I term the delivery rollers), before
they were out of the back rollers working in the melted metal, and therefore
they would not make their exit from the melted metal unless otherwise raised
and withdrawn.
In coating with some metal, such as lead, I have the opening between the
rollers, which I call delivering rollers, about fifteen or eighteen inches from

page_text: the surface of the melted metal, in order to avoid any of the coating metal
collecting upon them whilst the sheet is passing between them. If coating
with tin I place them at double, and with zinc at three times this distance. I
cause these intermediate rollers to revolve at a speed about 7 per cent. greater
than the back rollers working in the melted metal.
I place what I term the delivering rollers D, D, in a frame sloping over the
surface of the melted coating metal, as shewn in the annexed Drawing. I
make the upper roller of larger diameter than the lower one (the upper being
9 inches when the lower one is 6 inches diameter), so as to lap over it and
more readily catch the sheet as it approaches the opening between the rollers,
in order to prevent the sheet as it passes out of the delivery rollers taking a
curve downwards, when the lower roller is of smaller diameter than the upper
one. I place a small roller, say about 2 inches diameter, immediately behind
these delivery rollers, and with such arrangements for altering its position by
screws or otherwise that I am enabled to raise or depress it to such an angle with
these delivering rollers as to cause the coated metal, by falling upon or against
it as it passes out from these delivery rollers, to travel in the desired direction.
And I use a suitable guide piece of iron to bridge over the distance between
the lower delivery roller and the small 2-inch roller, so as to prevent the sheet
travelling astray before it reaches the said 2-inch roller. I cause these
delivery rollers to revolve at a speed about 10 per cent. greater than the back
rollers working in the melted metal. And I prefer to place them so that the
sheet or suitable pieces of iron or copper rising from the melted metal shall
ascend perpendicularly from the melted metal into the opening between the
rollers.
Lastly, I sometimes use a pair of chilled or case-hardened rollers hollow
and either heated by steam or not, through which I pass the plates after the
flux or dirt adhering to the surface has been cleaned of. The object of these
rollers is to give a polished or brightened surface to the sheet or plate, or
other suitable piece of iron or copper which has received its coating.
Having thus particularly described the nature of my Invention and the
manner in which the same is to be performed, I would remark that I do not
confine myself to the precise details as herein given, provided the principle of
my Invention be retained; but what I claim is,-
First, the passing in a wet state sheets, plates, or pieces of coated or
uncoated iron or copper (when to be coated with melted tin or lead, or
compounds of lead with tin,) into a flux (on the surface of the melted coating
metal) contained in a suitable apparatus as herein described.
Second, the immersion of sheets, plates, or pieces of iron or copper a second

page_text: time into the melted lead or tin, or compounds of lead with tin, as herein
described, in order to free them as far as possible from such flux as adheres
after the first immersion, when coating with a flux which clings to or rusts the
surface of the plate, such as waste or spoiled flux, or a flux of any metallic
salt, as chloride of tin.
Thirdly, the use of a pair of front outside rollers, as herein described,
between which the plates or sheets or pieces to be coated are passed into the
melted metal, and thence forward through it to a succeeding roller or rollers
as described ; and I also claim the mode herein described of making such
outside front rollers instrumental in confining the vapour of the flux as
described.
Fourthly, the arrangement of the rollers as described, so as to give a
horizontal or nearly horizontal travel to the sheets or suitable pieces of iron or
copper to be coated whilst passing under the surface of the melted metal.
Fifthly, the use of rollers completely submerged in the melted inetal.
Sixthly, the use of guide pieces or bars to conduct the sheets or plates or
suitable pieces of copper or iron to be coated in the desired direction, either
into the outside front rollers, or whilst passing under the melted metal into,
between, or from the pairs of rollers, and also out of the melted metal, as
described.
Seventhly, the use of what I terin an intermediate pair of rollers, as herein
described.
Eighthly, the outside rollers for receiving and delivering the sheets or plates
or suitable pieces of iron or copper after they emerge from the melted metal,
as herein mentioned, in combination with guides and other rollers or either, as
described.
Ninthly, the pair of polishing rollers, as described.
In witness whereof, I, the said Edmund Morewood, have hereunto set
my hand and seal, this Third day of April, in the year of our Lord
One thousand eight hundred and sixty.
