County of Middlesex, Capsule Manufacturer, for the Invention of "À
NEW MANUFACTURE OF GLAZED OR ENAMELLED PAPER."
NEW MANUFACTURE OF GLAZED OR ENAMELLED PAPER."
Sealed the 14th August 1858, and dated the 20th February 1858..
PROVISIONAL SPECIFICATION left by the said William Betts, at the
Office of the Commissioners of Patents, with his Petition, on the 20th
February 1858.
.I, WILLIAM BETTS, of Wharf Road, City Road, in the County of Middlesex,
Capsule Manufacturer, do hereby declare the nature of the said Invention for
"A NEW MANUFACTURE OF GLAZED OR ENAMELLED PAPER," to be as follows:-
I
prepare the paper by the application of size and colour in the usual
manner employed in the manufacture of fancy colored papers, applying thereto
French chalk or other similar material, and I then pass the paper so prepared
through a pair of rollers similar to the rollers employed in the manufacture of
tinfoil paper; and in calendering, whereby a glazed or enamelled surface
varying in the degree of burnish may be communicated to the paper.

by the said William Betts, in the Great Seal Patent Office on the
20th August 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BETTS, of Wharf Road, City Road, in the County of Middlesex, Capsule
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of February, in the year of our
Lord One thousand eight hundred and fifty-eight, in the twenty-first year
of Her reign, did, for Herself; Her heirs and successors; give and grant unto
me, the said William Betts, Her special licence, that I, the said William
Betts, my executors, administrators, and assigns, or such others as I, the
said William Betts, my executors, administrators, or assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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 "A NEW
MANUFACTURE OF GLAZED OR ENAMELED PAPER," upon the condition (amongst
others) that I, the said William Betts, 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 months next and
immediately after the date of the said Letters Pätênt:
NOW KNOW YE, that I, the said William Betts; do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
My Invention is described and ascertained in manner following, that is to
say:
The new manufacture of glazed or enamelled paper consists in preparing
paper with size and color, and burnishing the same by means of rolling friction
produced by the surfaces of two rollers, moving in the same. manner as the
rollers of an ordinary rolling mill, except that the surface of one of such
rollers revolves with a different velocity to the surface of the other, and
for that purpose I first prepare paper by the application of a mixture of size
and color, and brush such paper with French chalk in the usual manner of

page_text: preparing colored paper for enamelling; but instead of placing such prepared
paper between plates of metal, such as copper or zinc, and then passing such
plates & paper together thro' the rollers of a flatting or rolling mill, or
burnishing such paper by means of hand friction with an agate or other
suitable rubber, I pass the sheets of such prepared paper separately between
rollers.
Figure 1 in the accompanying Drawings shews a side view of the machinery
I employ for this purpose, and Figure 2 is a front view. In both of which
the ordinary gear work of such machinery is shewn. The paper when pre-
pared is passed between the top roller A and the centre roller B, this centre
roller is of paper. The rollers C and A are of iron, D is a small piece of
wood or other suitable material attached to the framework of the machine, to
which is attached a small spring E, which presses flatways below the axis of
the roller A; this spring is made of zinc, or other metal of such softness that
the constantly pressing on the roller A, it will not cause it to wear away,
and the object of this spring is to prevent the sheets of paper from coiling
round the roller as they might otherwise do occasionally. I lubricate the
rollers for the purpose of preventing the leaning or crumpling of the paper,
and the means I adopt for this purpose are as follows:-
Parallel with and above the axis of the roller C, and in such a manner as
to rest upon its surface, I fasten a piece of wood moving on a hinge shewn
separately Fig. F; which wood is covered with with cloth or flannel, and
upon this cloth I put sufficient mutton suet to keep such roller constantly and
evenly lubricated, and when the machine is in motion the other rollers are
also lubricated by contact of the roller C with B, and of B with A. Care
must be taken not to put so much grease as to stain the paper. Parallel
with the axis of the roller A, I suspend a bar of iron with adjusting screws,
this bar and the adjusting screws are shewn separately, G, Figure 4, and is
covered with several folds of cloth or canvas, and when the machine is in
motion the screws are adjusted so as to cause such covered bar to press
against the roller A, and thereby the same is kept perfectly free from dust or
dirt. His the ordinary adjusting lever, but instead of using weights, I fix on
the stretcher of the framework small standards of iron I, and by means of the
screw K. working in such standards, and attached to the lever H, I raise or
depress the rollers as may be required.
I wish it to be understood that I do not claim the exclusive use of the
several processes herein-before described or referred to, of coloring, brushing,
lubricating and rolling, except when the same are employed for the purposes

page_text: of my Invention. And I hereby declare that I claim as the Invention intended
to be secured by the said Letters Patent, the manufacture of glazed or
enamelled paper, by rolling and burnishing pressure as herein described.
In witness whereof, I, the said William Betts, have hereunto set my
hand and seal, this Twentieth day of August, in the year of our Lord
One thousand eight hundred and fifty-eight.
