PROVISIONAL SPECIFICATION left by the said Edmund Morewood at the
Office of the Commissioners of Patents on the 21st April 1876.
EDMUND MOREWOOD, of Llanelly, in the County of Carmarthen. "IMPROVE-
MENTS IN COATING METALS AND IN APPARATUS EMPLOYED THEREIN."
This Invention has for its object improvements in coating metals and in appa-
ratus employed therein.
In the process of coating iron or other metal sheets with tin or other metal,
I employ what I call a half-round finishing flux pot with machinery and
apparatus so fitted that plates which have been coated with melted metal after
being prepared by tallow, oil, or grease flux may be finished, improved, or
rectified whilst making a somewhat semicircular travel under the hot grease,
tallow, or oil contained therein, by passing between rollers coated with melted
metal.
At the bottom of this finishing flux pot is an opening by which any molten
metal, or scruff, or dirt, or settlings from the grease descend from the said finishing
flux pot into a receptacle which is set below, so that the rollers (some of which
work near the bottom of the finishing flux pot) may (whilst revolving) be as far
as possible out of the way of disturbing dirt, scruff, or settlings, or of planting
any on the plates which pass between them, and from the receptacle the metal,
grease, and dirt can be readily removed.
On the exit side of this finishing flux pot or vessel I cause the plates to pass up
between rollers working in troughs containing melted metal, so that they may be
supplied with fresh coating metal whilst passing between the rollers which revolve
in contact with the coating metal contained in such troughs, or such troughs may
[Price 6d1

page_text: contain fresh tallow, oil, or greasy matter of the quality and condition best suited
to finish such coated plates.
I prefer to use such half-round finishing flux pot in combination with a half-
round tinning pot. And the plates to be coatedfare passed into the melted coating
metal contained in such half-round tinning, pot through grease contained in a
flux box, as described in the Specification of a Patent granted to me and John
Henry Rogers, and dated the 24th March 1874. And on the exit side of such
half-round tinning pot I cause the plates to pass out between rollers revolving
in troughs, as described in the Specification of the Patent, No. 3126, in the year
1873.
I also find it desirable to use an additional pair of rollers close to the surface of
the melted metal on the exit side of the tinning pot, and under or between the legs
of the said trough.
Between the half-round tinning pot and the finishing flux pot I sometimes place
a dipping pot containing melted coating metal of good quality, and into this dipping
pot I occasionally dip the plates as they pass from the said half-round tinning pot
into the said finishing flux pot.
The arrangement of an opening and receptacle for scruff, dirt, or settlings may be
adapted to the grease flux on the exit side of a pot; in which the plates in process
of coating pass up from the coating melted metal to and through the finishing flux
before coming in contact with the air.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Edmund Morewood in the Great Seal Patent Office on the 21st
. October 1876.
EDMUND MOREWOOD, of Llanelly, in the County of Carmarthen. " IMPROVE-
MENTS IN COATING METALS AND IN APPARATUS EMPLOYED THEREIN."
This Invention has for its object improvements in coating metals and in apparatus
employed therein:
In the process of coating iron or other metal sheets with tin or other metal I
employ what I call a half-round finishing flux pot with machinery and apparatus
so fitted that plates which have been coated with melted metal after being prepared
by tallow, oil, or grease flux may be finished, improved, or rectified whilst making
a somewhat semicircular travel under the hot grease tallow or oil contained therein
by passing between rollers coated with melted metal.
At the bottom of this finishing flux pot is an opening by which any molten
metal, or scruff, or dirt, or settlings from the grease descend from the said finishing
flux pot into a receptacle which is set below, so that the rollers (some of which
work near the bottom of the finishing flux pot) may (whilst revolving) be as far
as possible out of the way of disturbing dirt, scruff, or settlings, or of planting any
on the plates which pass between them; and from the receptacle the metal, grease,
and dirt can be readily removed.
Figure 1 is a section of the half-round finishing grease pot; a is the passage for
the escape of molten metal and dirt; it is sealed at its lower end by dipping into
the receiver b, in which the metal is kept melted by a slow fire; c, c, are rollers by
which the plates are conducted through the pot.
From time to time, say once a day, the more solid impurities are removed by
means of a bent tool inserted at the lower end of the passage a, and by this means
the dirt is drawn down through the melted metal in the receiver b.
On the exit side of this finishing flux pot or vessel I cause the plates to pass up
hetween rollers, or preferably between rollers working in troughs containing melted

page_text: metal, so that they may be supplied with fresh coating metal whilst passing
between the rollers which revolve in contact with the coating metal contained in
such troughs. Or such troughs may contain fresh tallow, oil, or greasy matter of the
quality and condition best suited to finish such coated plates.
Figure 2 shews the half-round finishing grease pot combined with rollers working
in troughs containing melted coating metal as above described, the troughs and
rollers are arranged in the manner described in the Specification of my Patent,
No. 1696, bearing even date herewith. The plates first pass up between a pair of
rollers placed between the troughs d, and then through the rollers e which work.
in the troughs containing the melted coating metal.
I prefer to use such half-round finishing flux pot in combination with a half-
round tinning pot. And the plates to be coated are passed into the melted coating
metal contained in such half-round tinning pot through grease contained in a flux
box, as described in the Specification of a Patent granted to me and John Henry
Rogers, and dated 24th March 1874. And on the exit side of such half-round
tinning pot I cause the plates to pass out between rollers revolving in troughs, as
described in the Specification of the Patent, No. 3126, in the year 1873.
I also find it desirable to use an additional pair of rollers close to the surface of
the melted metal on the exit side of the tinning pot, and, under or between the legs
of the said trough, as stated in my Specification bearing even date herewith,
No. 1696.
Between the half-round tinning pot and the finishing flux pot I sometimes place
a dipping pot containing melted coating metal of good quality, and into this
dipping pot I occasionally dip the plates as they pass from the said half-round
tinning pot into the said finishing flux pot.
The arrangement of an opening and receptacle for scruff, dirt, or settlings may be
adapted to the grease flux on the exit side of the pot in which the plates in process
of coating pass up from the coating melted metal to and through the finishing flux
before coming in contact with the air.
At Figures 3 and 4 I have shewn the arrangement adapted to the apparatus
described in the Specification of my Patent bearing even date herewith, in which
apparatus the plates as they rise up from the melted metal in the coating pot are
drawn upwards by a pair of rollers c, situated between the lower ends of troughs d,
and then between rollers e working in melted metal or flux contained in the troughs,
in which apparatus also the ends of the space between the troughs are closed in by
ends or boxes, so that grease may be retained in the lower part of this space and
above the rollers c without spreading over the whole surface of the metal in the
tinning pot.
To be enabled to remove the scruff, dirt, or settlings from the grease so retained
in the space between the trough d, the box at one end of the space is open at the
bottom, and is sealed by this bottom dipping into the melted metal in the coating
pot.
Any scruff or dirt in the grease can be raked towards this end of the
space between the troughs by a tool introduced above the end box into the
space. The scruff or dirt so collected in the end box can be drawn out by a bent
tool through the metal, by which its bottom is sealed, as described in reference to
Figure 1.
Having thus described the nature of my said Invention and the manner of
performing the same, I would have it understood that I claim-
First. The arrangement of what I call a half-round finishing grease pot (in which
the plates have a somewhat semicircular travel) with a passage for the removal of
molten metal, scruff, dirt, and settlings, substantially as described.
Second. The combination of such half-round finishing grease pot with rollers
working in troughs containing melted coating metal or grease, between which the
plates pass as they rise up from the half-round finishing pot, substantially as
described.

page_text: Third. The arrangement for enabling molten metal, scruff, dirt, or settlings to be
withdrawn from the grease or flux on the exit side of a coating pot, substantially as
described.
In witness whereof, I, the said Edmund Morewood, have hereunto set my
hand and seal, this Twenty-first day of October, in the year of our Lord
One thousand eight hundred and seventy-six.
EDMUND MOREWOOD. (L.S.)
