We, CHARLES WILLIAM SMITH and WILLIAM MOULD, of Belmont, in the
County of Lancaster, and SAMUEL COOK and WILLIAM HENRY HACKING, of
Bury, in the said County, Machinists, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING," to be as
follows:-
This Invention consists, (first, of an improved taking-up motion for the
purpose of giving any desired number of picks to the inch without the aid of
the usual emery roller. We employ a rod or roller which is in contact with
the cloth on the cloth beam; from this rod is swung a straight lever, to which
an oscillating motion is given by the slay sword or tappet shaft of the loom by
means of a connecting rod. This lever imparts its motion to an upright double
lever, fixed on a stud in the frame side by means of a pin or stud working in
a slot at one extremity of the double lever. At its other extremity a forked
lever is swung by means of a pin, to which the same oscillating motion is
given. Working loose on a pin in the forked lever, a ratchet wheel, suitably

page_text: provided with one or more palls, is carried, and to which is attached a small
spur wheel gearing into a large spur wheel on the ordinary change wheel shaft
of the loom. It is evident that when a forward motion is imparted to the
forked lever by means of the before-described train of levers, the small spur
wheel, being prevented from revolving by the palls of the ratchet wheel to
which it is attached, will cause the large spur wheel into which it gears to
make a partial revolution, and that when the backward motion is given to the
forked lever, the small spur wheel being then released will revolve in the same
way as the sun-and-planet motion until it comes into the position it at first
occupied. The large spur wheel is prevented from revolving in the wrong
direction by means of one or more catches.
In another arrangement, in place of the forked lever, we use a filbow or fork
which clips the large spur wheel on each side, and is swung on the change wheel
shaft of the loom. The small spur wheel and ratchet wheel already described
are carried by the filbow or fork, which is operated upon by a modified arrange-
ment of the levers already mentioned. As the cloth accumulates on the cloth
roller or beam, the rod which presses against it will descend, and cause the
stud to fall in the slot of the double lever, and thereby decrease its motion in
the same proportion as the beam is filled.
Secondly, of a positive break or stop motion, which always stops the loom in
any given place. This arrangement consists of a lever which is provided with
a catch, the lever being so made as to fit the surface of a pulley or fly wheel
with which it has to come in contact. The pulley is also provided with a notch
or dent, and the catch is made to project a little through or past that part of
the lever which comes in contact with the surface of the pulley, and thereby
stops it from revolving when the lever is pressed against it. To prevent any
strain being given to the loom, the pulley or fly wheel is put loose on the first-
motion or crank shaft. A spring is attached to the first-motion or crank shaft,
and is also connected to the before-mentioned loose pulley. When the catch
comes in contact with the notch or dent, the. spring yields to a certain extent,
so that the loom may be stopped when running at any speed. The break lever
and catch are brought in contact with the pulley by a connecting rod, which is
in a horizontal position. This rod is in two parts, and is connected in
the middle by a spiral spring, so that when the weft fork lever is moved
it causes the rod to move and draw the break into contact with the pulley or
By wheel.
Thirdly, of a compound weighting lever, which dispenses with three-
fourths of the weight ordinarily used. We place the weight lever on a stud

page_text: about two inches from one end of it, and at a short distance below it a
grooved pulley is carried on another stud. The rope or chain is passed from
the yarn beam round or under the pulley, and then to the short end of the
weight lever.
