IMPROVEMENTS TO A LOOM FOR THE WEAVING OF COTTON AND OTHER GOODS BY STEAM OR WATER
Year: 1803

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HORROCKS, of Stockport, in the County of Chester, Cotton Manufacturer,
send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of His United Kingdom, bearing
date at Westminster, the Twentieth day of April, in the forty-third year of
His reign, give and grant unto me, the said William Horrocks, my execu-
tors, administrators, and assigns, His especial licence that I, the said William
Horrocks, my executors, administrators, and assigns, deputy or deputies,
servants or agents, during the term of years therein mentioned, should and
might make, use, exercise, and vend, within England, Wales, and the Town
of Berwick-upon-Tweed, my Invention of "IMPROVEMENTS TO A LOOM FOR THE
WEAVING OF COTTON AND OTHER GOODS BY STEAM OR WATER;" in which said
Letters Patent there is contained a proviso obliging me, the said William
Horrocks, by an instrument in writing, under my hand and seal, to cause
a particular description of the nature of my said Invention, and in what manner
the same is to be performed, to be inrolled in His Majesty's High Court of
Chancery within six calendar months next after the date of the said recited
Letters Patent.

page_text: wheel fixed on the above; C, a pinion wheel twice the diameter of B,
fixed on D, a shaft on which are fixed spiral wheels 1, 1, and E, E, tappets
which work on friction rollers fix'd on F, F, treadles. The greatest radii
of the tappets being fixed transversely on the shaft D, the treadles are
depressed alternately, and thus work G, G, the yealds, which are tied to
them; H, H, arms which connect the main shaft or crank with I, the
lathe; K, K, two levers hanging on centers, the inner ends of which are
heaviest, and are flush with the inside of L, L, the boxes; M, M, two levers
fixed on a rod which runs from one to the other. On the middle of this rod is
fixed N, another lever working with M, M, and which I call the stop; O, a
projecting piece on the front of the lathe. If by any accident the shuttle
should not come into the box, the levers K, K, would turn on their centers
by the pressure of levers M, M, which would remain inert, the resistance of
K, K, being less. Now, the stop N, being fixed on the same rod as M, M,
would remain inert also, and consequently stop the loom when it (N) touched
the projecting piece O, which would happen before the reed came so near the
cloth as to injure the webb. The shuttle coming into the box prevents any
action in K, which then raises levers M, M, and consequently N, high enough
to pass over the stop O. P, a lever, to the end of which are tied Q, cords
tied to R, pickers, sliding in boxes L, L, through a grove at bottom, and
on spindles at top; S, the yarn beam; T, a roller, on which the yealds are
hung; U, the breast beam; V, the cloth beam, to which are fixed
W, W, W, W, W, ratchet wheel, catch, pullies, cord and weight, which
wind the cloth up as wove; 1, 1, spiral wheels on shaft D; 2, 2, levers, to
which weights 8, 8, are hung; 3, 3, cranks (pullies and chains will answer
the same purpose); 4, 4, rods of iron or any other material passed through
cylindrical apertures in levers 2, 2, and secured with a nut. These rods having
room to play through the levers prevent the one acting against the other; 5, a
cross piece connecting the cranks 3, 3, with 6, a crank, fixed on 7, a shaft;
8, 8, weights, which being attached to levers 2, 2, they are alternately raised

page_text: by the revolution of the spiral wheels on shaft D, and depressed by falling
from the longest to the shortest radii of the same. The rods 4, 4, being
connected with the levers 2, 2 and joined to the cranks 3, 3, which are con-
nected with the crank 6 by means of the cross piece 5, the crank 6 works on
the shaft 7 as a centre (these cranks are clearly shewn in Figure 4). To this
shaft is fixed the lever P, to which is tied the cords Q; these cords are tied to
the pickers R, R. Now, supposing one of the levers 2 to be on the longest
radii of one of the spiral wheels 1, by the revolution of the said wheel it
would drop to the shortest radii of the same. This would move the cranks
3, 3, and 6, and consequently the lever P, with a sufficient force to throw the
shuttle from one box to the other, and the depression of the other lever 2
would throw it back again. Those parts of the machine marked with figures,
are what I claim as my own Invention. The machine may be worked by
steam or any other force.
AND BE IT REMEMBERED, that on the same Twentieth day of August,
in the year above mentioned, the aforesaid William Horrocks came before our
Lord the King in His Chancery, and acknowledged the Specification afore-
said, and all and every thing therein contained, in form above written.
And also the Specification aforesaid was stamped according to the tenor of
the Statute in that case made and provided.
Inrolled the Twelfth day of October, in the year above written.
