AN IM- PROVEMENT OR IMPROVEMENTS IN MILL BANDING." PROVISIONAL SPECIFICATION
Year: 1853

page_text: LETTERS PATENT to John Turner Wright, of Birmingham, in the
County of Warwick, Manufacturer, Edwin Payton Wright, of
Birmingham aforesaid, Manufacturer, and William Asbury, of
Birmingham aforesaid, Engineer, for the Invention of "AN IM-
PROVEMENT OR IMPROVEMENTS IN MILL BANDING."
PROVISIONAL SPECIFICATION left by the said John Turner
Wright, Edwin Payton Wright, and William Asbury at the
Office of the Commissioners of Patents, with their Petition, on
the 31st October 1853.
We, JOHN TURNER WRIGHT, of Birmingham, in the County of
Warwick, Manufacturer, EDWIN PAYTON. WRIGHT, of Birmingham
aforesaid, Manufacturer, and WILLIAM ASBURY, of Birmingham
aforesaid, Engineer,. do hereby declare the nature of the said Inven-
tion for "AN IMPROVEMENT OR IMPROVEMENTS IN MILL BANDING" to be as
follows:
Our Invention relates to such mill banding as is usually made of

page_text: gutta percha, whether the same be round (or cylindrical) or flat, or
of other figure. The object of our said Invention is to prevent the
elongation which the said banding experiences when in use, as well as
to strengthen the same. Our said Invention consists in introducing
into the said banding wires, cords, threads, catgut, or wires or lines of
any other suitable substance, not liable to permanent elongation. In
applying the said wires, &c. to flat banding, we introduce the same
between two strips or bands of gutta percha, and by means of heat and
pressure combine the said strips or bands together so as to form one
band, with the wires, &c. embedded in the middle thereof. In applying
our Invention to round (or cylindrical) banding we introduce the said
threads, wires, &c. into the said banding by any of the well known
methods of coating or covering wire with gutta percha.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Turner Wright, Edwin Payton Wright,
and William Asbury in the Great Seal Patent Office on the
29th April 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, . we,
JOHN TURNER WRIGHT, of Birmingham, in the County of Warwick,
Manufacturer, EDWIN PAYTON WRIGHT, of Birmingham aforesaid,
Manufacturer, and WILLIAM ASBURY, of Birmingham aforesaid, En-
gineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirty-first day of October, in the
year of our Lord One thousand eight hundred and fifty-three, in the
seventeenth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said John Turner Wright, Edwin
Peyton Wright, and William Asbury, Her special licence that we,
the said John Turner Wright, Edwin Payton Wright, and William
Asbury, our executors, administrators, and assigns, or such others as
we, the said John Turner Wright, Edwin Payton Wright, and William
Asbury, our executors, administrators, and assigns, should at any time

page_text: 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
"AN IMPROVEMENT OR IMPROVEMENTS IN MILL BANDING," upon the con-
dition (amongst others) that we, the said John Turner Wright, Edwin
Payton Wright, and William Asbury, by an instrument in writing under
our hands and seals, or under the hand and seal of one of us, 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 Patent.
NOW KNOW YE, that we, the said John Turner Wright, Edwin
Payton Wright, and William Asbury, 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:
Our Invention relates to such mill banding as is usually made of
gutta percha, or compositions of which gutta percha is the principal
ingredient, and is applicable to mill banding which is round (or
cylindrical), or flat, or of other figure. The object of our said Invention
is to prevent the elongation which is produced in mill banding made
of gutta percha, or compounds of gutta percha, by usc, as well as to
strengthen the said mill banding. Our said Invention consists in intro-
ducing into mill banding made of gutta percha, or compounds of guttą
percha, metallic wires or cords, or threads made of hemp or other
fibrous substance, or catgut, or wires, lines, cords, or threads of any
other material having suflicient flexibility, and not liable to permanent
elongation by long continued moderate tension. In applying the said
wires, cords, threads, or lines to flat mill banding, we take two flat
strips or bands of gutta percha, or compound of gutta percha, the com-
bined thicknesses of the said two strips or bands being about equal to
the thickness which it is intended the finished mill banding shall have;
we place the said wires, cords, threads, or lines between the said strips
or bands of gutta percha, or compound of gutta percha (the said wires,

page_text: or com
cords, threads; or lines being by preference placed parallel to and
equi-distant from each other, and parallel to the sides of the bands or
strips-of-gutta-percha, or compound of gutta percha); we then apply
heat and pressure to the said strips or bands of gutta percha,"
pound of gutta percha, and thereby combine the said strips or bands
together, so as to form one band with the wires, cords, threads; 'or-linies
embedded therein. In applying our Invention to round (or cylindrical)
mill banding, we coat or cover each of the said wires, cords; threads,
or lines with gutta percha, or compound of gutta percha, by any of the
well known processes of coating or covering wires with gutta percha, and
we afterwards combine any required number of the coated wires; lines,
threads, or cords together by heat and pressure, so as to produce á
cylindrical or other shaped band of gutta-percha, or compound of gutta
percha, with the wires; threads, cords, or lines embedded therein.. In
joining together the ends of mill banding, made according to our
Invention, we effect the same by fusing or uniting the gutta percha,
or compound of gutta percha, by heat; or we remove the gutta percha,
or compound of gutta percha, from the ends of the wires, cords, threads,
or lines, and-join the opposite ends of each wire, cord, thread, or line by
soldering, hooking, tyeing, twisting, or otherwise fastening the same
together, and we afterwards cover the joined ends of the wires, cords,
lines, or threads, with gutta percha, or compound of gutta percha.
Having now described the nature of our said Invention; and the
'manner in which the sanie is to be performed, we wish it to be under-
stood that we do not limit ourselves. to the precise methods of carrying
our Invention into effect herein described, as the same may be varied
without departing from the nature of our said Invention; for example,
although in making flat mill banding, we prefer introducing wires,
threads, cords, or lines between two-strips or bands of gutta percha, and
combining the said strips or bands by heat and pressure, yet three or
other number of such strips or bands of gutta percha or compound of
gutta percha may be used, and wires, cords, lines, or threads intro
duced between all the opposed surfaces of the said strips or bands.
But we claim as our Invention the introduction of wires, lines, threads,
or cords of metal or other material having flexibility, and not being

page_text: liable to permanant elongation by tension, into mill bandings made of
gutta percha, or compound of gutta percha, as herein-before described.
In witness whereof, we, the said John Turner Wright, Edwin
Payton Wright, and William Asbury, have hereunto set our
hands and seals, this Twenty-eighth day of April, in the year of
our Lord One thousand eight hundred and fifty-four.
