page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
TAYLOR, of Manchester, in the County of Lancaster, Machine Maker, send
greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Fourth day of February
instant, give and grant unto me, the said Joseph Taylor, and PETER TAYLOR,
of Manchester aforesaid, Machine Maker, our exors, adñiors, and assigns, His
Majesty's especial licence, full power, sole privilege and authority, that we,
the said Joseph Taylor and Peter Taylor, our exors, admors, and assigns, and
every of them, by ourselves or by our deputies, servants or agents, or such
others as we, the said Joseph Taylor and Peter Taylor, our exors, admors, or
assigns, should at any time agree with, and no others, from time to time and at
all times thereafter, during the term of years therein expressed, should and law-
fully might make, use, exercise, and vend, a certain Invention therein mentioned,
to wit, "A CERTAIN IMPROVEMENT IN A LOOM TO BE USED IN WEAVING COTTON,
LINEN, WOOLLEN, WORSTED, SILK, OR OTHER CLOTH, OR CLOTH MADE OF ANY TWO OR
MORE OF THE SAID MATERIALS," within that part of the United Kingdom of
Great Britain and Ireland called England, the Dominion of Wales, and the
Town of Berwick-upon-Tweed, in such manner as to us, the said Joseph
Taylor and Peter Taylor, our exors, adññors, and assigns, or any of them,
should in our discretion seem meet; in which Letters Patent there is (among
other things) contained a proviso obliging us, the said Joseph Taylor and
Peter Taylor, or one of us, particularly to describe and ascertain the nature of
our said Invention, and in what manner the same is to be performed, by an
instrument in writing under our hands and seals, or under the hand and seal

page_text: of one of us, and to cause the same to be inrolled in His Majesty's Court
of Chancery within two calendar months next and immediately after the
date of the said Letters Patent, as in and by the said Letters Patent, relation
being thereunto had, will more fully appear.
NOW KNOW YE, that in pursuance of and in compliance with the said
recited proviso, I, the said Joseph Taylor, do hereby declare that the nature
of the said Invention, and the manner in which the same is to be performed,
is as herein-after mentioned :-
Our Invention consists of certain machinery applicable to looms, the lathe of
which is moved by the circular motion of two or more cranks, and the object
of our Invention is to cause the lathe to move backward and forward twice,
by means of one revolution of the cranks.
Our machinery consists of the following parts, connected as herein-after
mentioned, viz*:-
A, B, described or delineated in the Drawings in the margin hereof,
are two pieces of iron or other proper material, which we call arms, connected
together in the middle by a circular pin forming a joint, which will move freely
upwards and downwards, one end of which arms so joined is affixed, by means
of a circular pin on which it can freely move upwards or downwards, to one
arm of the lathe about three inches above the level of the top of the reed, (the
lathe being suspended from the upper part of the loom,) and the other end of
which arms so joined is affixed to the side or some other firm and immoveable
part of the loom on the same or nearly the same level by another circular pin
on which it can freely move upwards and downwards, so that when the joint is
either raised or depressed the lathe moves backward, and when both the arms
form a straight line the lathe in weaving is pushed up to the cloth. C, also
described or delineated in the margin hereof, is a connecting rod of iron or other
proper material, one end of which is affixed either on the circular pin which
joins together the two arms A, B, or on some other circular pin near thereto
on which it can freely move, and the other end of which is fixed on the crank,
which turns round to give motion to the lathe, so that every time the crank
turns round it alternately raises and depresses the joint of the arms, and thereby
moves the lathe twice to and from the cloth in every single revolution of the
crank. The like arms are to be fixed in like manner at one end thereof to
the other arm of the lathe, and at the other end thereof to the other side or
other firm and immoveable part of the loom, with the like connecting rod and
the like crank to work the same in order to give an equal motion and power
to each end of the lathe. We usually make each of the arms about eight
inches in length between the centres of the pins on which they move when
calicoes and other light goods are to be woven, and about ten inches in length

page_text: when fustians or other strong goods are to be woven; and we usually make
the connecting rod about two feet in length between the centre of the joint of
the arms and the centre of the crank which moves it, but these lengths may
be varied a little without material injury. And we usually make the crank
about seven inches in length from the centre of the crank shaft to the centre
of that part of the crank which moves the connecting rod when calicoes or
other light goods are to be woven, and about seven inches and an half in
length when fustians and other strong goods are to be woven; and we usually
place the crank shaft under or nearly under the joint of the arms when the
arms form a right line. The crank shaft must be placed at such a distance
below the joint of the arms that the crank in forming a revolution may move
the joint of the arms alternately equal or nearly equal distances above and
below the level formed by the arms when they are in a right line, in order to
make the strokes of the lathe equal. This may be easily adjusted by lengthen-
ing or shortening the connecting rod by any common apparatus in the middle
of the rod for that purpose
We do not claim the crank as any part of our Invention.
In witness whereof, I, the said Joseph Taylor, have hereunto set my
hand and seal, this Twenty-third day of February, in the year of our
Lord One thousand eight hundred and fifteen.
JOSEPH TAYLOR. (L.S.)
