Year: 1875

page_text: LETTERS PATENT to Alfred Moore, of No. 356, Euston Road, in
the County of Middlesex, for the Invention of "IMPROVEMENTS IN
APPARATUS FOR APPLYING A LIQUID COATING TO FLEXIBLE METALLIC FABRICS
OR SHEETS."
"
PROVISIONAL SPECIFICATION left by tho said Alfred Mooro at tho
Office of the Commissioners of Patents, with his Petition, on the
6th March 1875.
I, ALFRED MOORE, of No. 356, Euston Road, in the County of
Middlesex, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR APPLYING A LIQUID COATING TO FLEXIBLE
METALLIC FABRICS OR SHEETS," to be as follows:-
My Invention relates to apparatus for applying a coating to flexible.
metallic fabrics or sheets, as in the process of galvanizing iron, by
drawing the articles to be coated through a bath of molten metal or
other coating liquid and cleansing and smoothing the coating applied.

page_text: The chief object of my Invention is to increase the amount of surface
that can be coated with a bath of given dimensions to economisc time
and to effect at the same operation the cleansing and smoothing of the
coated surface. For this purpose I mount in the bath and under the
level of the liquid contained therein two rollers, one above the other.
I pass the fabric, such as netting, or the sheets linked together down
into the bath at one side thereof, and under the roller therein, that is to
say, one line of such fabric or sheets under the one roller and another
such line under the other roller, and I bring them up at the other side
of the bath through the sand or other materials employed for removing
superfluous coating liquid, and thence over rollers or guides to winding
drums or reels. Between the said rollers or guides and the winding
drums or reels I mount revolving brushes, which act on the surface of
the fabric or sheet passing under them, so as to cleanse and smooth it.
These brushes may be driven from any convenient primo mover, but I
prefer to drive them by straps or other suitable gearing from the
winding drums or recls, so that the movement imparted to the latter
for advancing the material acted on serves at the same time to work the
brushes.
Instead of two sets of submerged rollers with their guides, brushes,
and winding drums, there may be three or more sets arranged as I have
described, so that through a singlo bath a number of lines of fabric or
sheets can be drawn at the same time.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Alfred Moore in the Great Seal Patent Office on 2
the 4th September 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
MOORE, of No. 356, Euston Road, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her 3
Letters Patent, bearing date the Sixth day of March, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-eighth year of Her reign, did for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Alfred Moore, Her special

page_text: license, that I, the said Alfred Moore, my executors, administrators, and
assigns, or such others as I, the said Alfred Moore, 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
5 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 APPARATUS FOR APPLYING A LIQUID COATING TO FLEXIBLE METALLIC FABRICS
OR SHEETS," upon the condition (amongst others) that I, the said
O Alfred Moore, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, 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
5 months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Alfred Moore, 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
O by the following statement thereof, reference being had to the accom-
panying Sheet of Drawings and to the figures and letters marked thereon,
that is to say :-
My Invention relates to apparatus for applying a coating to flexible
metallic fabrics or sheets, as in the process of galvanising iron, by
3 drawing the articles to be coated through a bath of molten metal or
other coating liquid and cleansing and smoothing the coating applied.
The chief object of my Invention is to increase the amount of surface
that can be coated with a bath of given dimensions, to economise time,
and to effect at the same operation the cleansing and smoothing of the
) coated surface. For this purpose I mount in the bath and under the
level of the liquid contained therein two rollers, one above the other.
I pass the fabric, such as netting, or the sheets linked together into the
bath at one side thereof and under the roller therein, that is to say, one
line of such fabric or sheets under the one roller, and another such line
under the other roller, and I bring them up at the other side of the bath
through the sand or other materials employed for removing superfluous
coating liquid, and thence over rollers or guides to winding drums or

page_text: reels. Between the said rollers or guides and the winding drums or reels
I mount revolving brushes, which act on the surface of the fabric or
sheet passing under them, so as to cleanse and smooth it. These
brushes may be driven from any convenient prime mover, but I prefer
to drive them by straps or other suitable gearing from the winding 5
drums or recls, so that the movement imparted to the latter for
advancing the material acted on serves at the same time to work the
brushes.
Instead of two sets of submerged rollers with their guides, brushes,
and winding drums, there may be three or more sets arranged as I have 1
described, so that through a single bath a number of lines of fabric or
sheets can be drawn at the same time.
The accompanying Drawing shows a transverse section of my before
described improved apparatus for coating metal fabrics or sheets.
A, A¹, are reels containing the wire netting or metal sheets to be 1
coated. The reels are mounted on trunnions in a framing B, and the
wire netting or sheet metal represented by the dotted lines C, C', is led
from these round two guide rollers D, D', immersed in the bath E
containing the molton metal or other liquid with which the wire netting
or sheets are to be coated. From these guide rollers the wire netting
is led upwards, passing first through the receptacle F containing sand or
other material for removing the superfluous coating of liquid, and
thence over guide rollers G, G, H, II', carried by the framing N to
winding reels I, I', on which the coated metal is wound. Between tho
rollers G, G', and H, H', aro mounted revolving brushes K, K³, which
act on the surfaces of the netting or sheet metal C, C³, so as to cleanse
and smooth them. These brushes are driven by means of straps L, L,
and pullics from the gearing M, M', by which the recls I, I', are rotated,
the gearing for each winding reel being either worked by hand or from
any convenient source of motive power, and either separately or
together.
It will be understood that there may be several such sets of reels,
guide rollers, and brushes arranged side by side in the length of the
machine so as to operate on a number of lengths of netting or sheet
metal at the same time.
Having thus described the nature of my Invention, and in what
manner the same is to be performed, I claim, the use of apparatus

page_text: arranged and operating substantially as herein described for applying-a
liquid coating to flexible metallic fabrics or sheets, wherein two or more
lengths of such metallic fabrics or sheets are passed one above the other
round two or more guide rollers immersed in the liquid bath, whenco
they are passed over guide rollers to winding reels, the superfluous
coating being removed from the surfaces of the metallic fabric or sheets
by means of revolving brushes.
In witness whereof, I, the said Alfred Moore, have hereunto set my
hand and seal, this Thirty-first day of August, in the year of
our Lord One thousand eight hundred and seventy-five.
