page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENJAMIN
BLACKMORE, of Wandsworth, in the County of Surry, Bolting Cloth Weaver,

WHEREAS His most Excellent Majesty King George the Third did, by

at Westminster, the Thirty-first day of March, in the fortieth year of
His reign, give and grant unto me, the said Benjamin Blackmore, my
executors, administrators, and assigns, His special licence, full power, sole
privilege and authority, that I, the said Benjamin Blackmore, during
the term of years therein expressed, should and lawfully might make, use,
exercise, and vend, within that part of the Kingdom of Great Britain
called England, the Dominion of Wales, and Town of Berwick-upon-Tweed,
my
Invention of "AN ELASTIC SPRING, FOR THE IMPROVEMENT AND MORE COM
PLEAT MANUFACTURING AND FORMING OF BOLTING CLOTHS WITHOUT SEAMS, TO BE
USED BY MILLERS FOR DRESSING OF FLOUR;" in which said Letters Patent"
is contained a proviso, requiring me, the said Benjamin Blackmore, under my
hand and seal, to describe and ascertain the nature of my said Invention, and
in what manner the same is to be performed, by an instrument in writing
under my hand and seal, and cause the same to be inrolled in His Majesty's
High Court of Chancery with one calendar month next and immediately after
the date of the said recited Letters Patent, as in and by the same, relation
being thereunto, may more fully and at large appear.
NOW KNOW YE, that in pursuance of and compliance with the said
proviso, I, the said Benjamin Blackmore, do hereby declare that the nature

page_text: of my said Invention, and the manner in which the same is to be performed,
are described and ascertained as herein-after set forth, and by the Plans thereof
drawn at the foot of these Presents, and the references thereto hereafter also set
forth, (that is to say):-
The warp being put into the loom in the ordinary way, is passed through the
harness from thence, and also through the reed, at the rate of four threads to
each dent; it is then tied to the breast roll, and set to work in the following
manner The harness is tied from near. the ends of the virgeezes to the
extremities of two sets of tumblers at the top of the loom; the upper set of
lams is fastened with cord to the centre of the harness, which set is denominated
fallers; then from the center of each of the under set of lams, called risers, is
fixed a cord, which supports them, and is brought through the upper lams,
harness, and warp, and leads to the center of the two sets of tumblers, where it
is fastened. The treadles, being eight in number for the fine sorts of cloths,
and four for the coarse, are fastened to the cordage of both sets of lams. There
is also an additional treadle to each kind of work, fastened.as the others, "for
the purpose, of dividing the two parts. of the harness for the upper and lower
part of the cloth, by which they appear as two distinct harnesses. The work is:
then commenced by treading two treadles to make an opening, and throwing
the shuttle from the right hand to the left; then by treading two.treadles more
to make an opening for the, under part of the cloth, and throwing' the left hand
to the right; then by treading two treadles more to make a cross opening for the
upper part of the cloth, and throwing the shuttle from right to left: This
coarse is continued till an inch or two of cloth is made; an instrument called
a pair of temples is thien passed between tlie upperrand. under part of the cloth
to stretch, it as wide as the warp is extended in the reed: A tool, called a
regulator, and foined according to the, quality and dimensions of the reed of a
number of pieces of lead wire, known by the name of lingols, suspended by as
many single or, twisted horse hairs from a perforated piece of cane," is then
introduced by dropping, each lingol, so as that the hair. by which they are
suspended, shall equally divide the four threads of the warp between each dent
in the reed...The cane which composes the upper part of the regulator is then
drawn up into, a cavity plowed out in the hand ball, and all the lingols are then
suspended in an, opening,, made in the under ball of the batterns so as to keep.
tight the hairs, which are now before the,reed, and resting against a brass bolster.
The patent elastic spring is composed of horse-hair line, catgut, or any other elastic.
spring and two worms, made of iron, brass, copper, or any other wire. The cat-
gut or such like being, doubled, is then passed froni end, to end of the regulator
between each hair, or each piece of twisted hair, or between every two, hairs,

page_text: in such a manner, that those single hairs, twisted hairs, or each two hairs
(according to the will of the Patentee) which are before one part of the doubled
catgut or cord shall be behind the other part. To each end of the
double catgut is then fixed one of the worms, which when the catgut is drawn
tight are hung on two hooks, one at each end of the opening in the under
ball of the batterns, and just below the brass bolster, before mentioned; when
the batterns are screwed close the work is proceeded on in the manner before
described; the spring will then operate as a preventative to any of the lingols
rising to break the warp or to do any other, yet in so gentle a manner that
they themselves will not be damaged by the resistance of the springs, nor make
the cloth streaky, by tightening too much the hairs by which they are
suspended. The lingols are hereby also kept from intersecting each other.
In witness whereof, I, the said Benjamin Blackmore, have hereunto set
my hand and seal, this Twenty-ninth day of April, in the fortieth year
of the reign of our Sovereign Lord George the Third, by the grace of
God, of Great Britain, France, and Ireland, King, Defender of the
Faith, and so forth, and in the year of our Lord One thousand eight
hundred.
Inrolled the same Twenty-ninth day of April, in the year above written.
