Year: 1875

page_text: LETTERS PÅTENT to Alexander Mullord, of Hoxton, in the County
of Middlesex, for the Invention of "IMPROVEMENTS IN ⚫ SATINING
OR IMPREGNATING WITH CERTAIN SUBSTANCES TISSUE AND OTHER PAPER.”
PROVISIONAL SPECIFICATION left by the said Alexander Mullord at
the Office of the Commissioners of Patents, with his Petition, on
the 22nd December 1875.
I, ALEXANDER MULLORD, of Hoxton, in the County of Middlesex,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN SATINING OR IMPREGNATING WITH CERTAIN SUBSTANCES TISSUE AND OTHER
PAPER," to be as follows:-
,
"
satining" tissue and
paper transparent or
My Invention relates to the process known as
other paper, and which consists in rendering the
nearly transparent by impregnating it with wax or other analogous
material.

page_text: My Invention consists in satining or impregnating paper in the roll
instead of in sheets, as heretofore.
According to my Invention the paper in a continuous length, or it
may be sheets of paper cemented together to form a continuous length, is
unwound from the roll, and passed through a trough or other receptacle
containing melted wax or other "satining" material, and thence over
a scraper or roller and under a pad or another scraper or roller pressing
on the first, and then to a roll on which the paper is wound, and by
which it is drawn continuously through the trough and between the
scrapers or rollers. The latter serve to remove the superfluous wax or
other material used.
Instead of passing the paper through a bath of the material I may
sprinkle the same in a cold and powdered state on the continuous length
of paper, which is then brought into contact with hot surfaces or rolls,
whereby the "satining" material is melted and absorbed by the paper.
Another method consists in sprinkling the satining material on the
paper as it is being wound up in the form of a roll, so that between
each two convolutions of the paper there is a layer of satining
material. The roll is then placed in an oven or other hot receptacle until
the roll becomes heated through, and the wax or other material melts
and permeates the whole of the paper.
SPECIFICATION filed in pursuance of the conditions of the Letters
Patent, and of an Order of the Lord Chancellor, by the said Alexander
Mullord in the Great Seal Patent Office on the 7th July 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDER
MULLORD, of Hoxton, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of December, in
the year of our Lord One thousand eight hundred and seventy-five, in
the thirty-ninth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Alexander Müllord, Her
special licence that I, the said Alexander Mullord, my executors, ad-
ministrators, and assigns, or such others as I, the said Alexander Mullord,"

page_text: Another method consists in sprinkling the wax on the paper as it is
being wound up in the form of a roll, so that between the convolutions
of the paper there is a layer of wax. The roll is then heated in an oven
until the wax is melted and permeates the whole of the paper.
In order that my Invention may be more readily understood I will
proceed to describe the process and machine more in detail with
reference to the accompanying Drawings, in which Figure 1 represents
a side elevation (partly in section) of the machine for satining a con-
tinuous length of paper by passing it through a bath of the melted wax;
Figures 2, 3, 4, and 5 illustrate details; they represent cross sections
and part elevations of the different arrangements of scrapers, pads, and
rollers which I may employ with this machine.
Figures 6 and 7 respectively illustrate the process of satining paper
by sprinkling the wax upon it in a powdered state, and melting it by
passing the paper upon or between heated surfaces.
Referring to Figure 1 A is a cauldron heated by steam coil, gas, or
otherwise, and containing the wax; B is a trough kept heated in a
similar way, and supplied by a pipe C with melted wax from the
cauldron A. This trough is of rather greater length than the width of
the sheet of paper to be satined; D is a roller dipping in the trough B, 1
beneath which the sheet of paper. is passed; E is the roll of paper carried
on a spindle supported and turning in bearings in two end frames F,
which are connected rigidly together by cross bars so as to form one
frame, which is suspended from a chain G passing over pulleys H over-
head and counterweighted so as to be readily raised from the trough
when desired; I are guide rollers mounted to turn loosely between the
frames F around one or more of these rollers I the paper (represented
by a thick line) is led, and thence beneath the roller D, which is
immersed in the bath of wax. The paper E..after passing through a
bath of melted wax, is carried between a scraper L and pad M, as shown
more clearly in Figure 2, or between a pair of scrapers L, L, as shown
in Figure 3, or a pair of rollers P, P, as in Figure 4, or a pair of
pads M, M, as in Figure 5 (according to the kind of paper), the scrapers,
rollers, or pads being weighted or otherwise pressed together in order to
retain the superfluous wax and return it to trough B. From thence
the paper passes to a roller N placed at a sufficient distance from the
trough to allow of the wax cooling, which may be assisted by a blast of
..

page_text: cold air directed against the paper from pipe O. The roller N is
mounted in bearings, and turned by hand. or power to draw the paper
from the roll E through the trough and scrapers, rollers, or pads, and
wind it on the roller N. The scraper L is of metal, and the pads M. of
leather or other suitable material. The rollers P are of metal, and
should be heated by gas or steam if they are not sufficiently heated by
their proximity to the trough B. As the rollers are free to revolve with
the paper the latter is not subject to so great a strain as when passed
between fixed scrapers, which is an advantage with certain kinds of
papers.
Referring to Figure 6 E is the roll of paper, as before, and R is a
hopper or receptacle for the wax in a cold powdered state; S is a hot
plate placed immediately beneath hopper R, and kept heated by steam,
gas, or otherwise, along which the paper from the roll E is drawn, and
as it passes beneath the hopper R it is sprinkled evenly with the wax,
which is melted and absorbed by the heated paper. The latter then
passes on to a roller N, upon which it is wound after being cooled, as
before described.
In Figure 7 a pair of rolls T, T, heated internally by steam or gas
introduced through their axes is substituted for the hot plate S. The
paper as it is drawn off from the roll E is sprinkled with wax from
hopper R, and then passes through the heated rolls T, is cooled and
wound on a roller as before.
I use
For the third method, which consists in winding up the paper with a
layer of wax between it, and then heating the whole in an oven,
the arrangement above described, and shown in Figure 6, but without
heating the plate S. The paper, sprinkled with powdered wax, as before,
is wound up in a roll at N, with a layer of wax between the convolutions,
and then heated as above mentioned.
) Having described the nature of my Invention, and the manner of
performing the same, I declare that what I claim as the Invention to
be protected by the herein-before in part recited Letters Patent is,-
1st. The process or processes of " I satining" a roll or continuous
length of paper, and which consists in impregnating paper with wax
5 or similar substances while in a roll or continuous length, as herein
specified.

page_text: 2nd. The several apparatus herein described and illustrated in the
Drawings when used for "satining" continuous lengths of paper, sub-
stantially as herein specified.
In witness whereof, I, the said Alexander Mullord, have hereunto
set my hand and seal, this Sixth day of July, in the year of 5
our Lord One thousand eight hundred and seventy-six.
