Year: 1871

page_text: LETTERS PATENT to Ellis Butterworth, of Calder Cottage, near
Rochdale, and Matthew Hawksworth, of No. 6, Chester Street,
Rochdale, both in the County of Lancaster, for the Invention of
" IMPROVEMENTS IN LOOMS FOR WEAVING."
Sealed the 7th May 1872, and dated the 9th November 1871.
PROVISIONAL SPECIFICATION left by the said Ellis Butterworth
and Matthew Hawksworth at the Office of the Commissioners
of Patents, with their Petition, on the 9th November 1871.
We, ELLIS BUTTERWORTH, of Calder Cottage, near Rochdale, and
MATTHEW HAWKSWORTH, of No. 6, Chester Street, Rochdale, both in
the County of Lancaster, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING," to be as follows:-
Our Invention relates first to the picking motion, and consists as
follows: On the tappets that work the healds are fastened studs on

page_text: which pullies are mounted, which as they are taken round by the
revolution of the tappet shaft come in contact with and depress pro-
jections on levers which are mounted loosely at one end on a stud, and
to the other end which is free to move up and down is attached a strap,
the other end of which is fastend to and coils round the boss of a pulley
which is mounted on a stud that is fast to the lathe of the loom. On
this pulley is mounted a strap which goes under the lathe and round
a pulley which is mounted on a stud fast to the end of the lathe. To
this strap is fastened the picker which passes up through slots in the
bottom of the lathe. Around the other boss of the pulley on which is
mounted the strap that goes under the lathe is coiled a strap, one
end of which is fast to the pulley and the other end is taken hold of
by a spring which, after the pick is made, pulls the picker back to
the end of the lathe; by this means picking sticks and lathe spindles are
dispensed with.
Secondly. Our Invention relates to the takeing-up motion which we
propose to make as follows:-To the lathe sword we attach a stud in which
goes one end of a connecting rod the other end of which takes holds of a
stud which is fast to a link, this stud takes into a slot in a rocking lever,
in which is a slide or catch which, when going in one direction, pushes
a pulley part of a revolution, which through a train of wheels turns the
cloth roller. The link mentioned above is taken hold of by a lever
mounted on a shaft, and on this shaft is another lever which presses
against the cloth on the roller, and thus as the cloth roller gets
larger in diameter the stud in the slot of the rocking lever is moved so
as to take up the cloth at or near an uniform speed.
Instead of a pulley a ratchet wheel with straight, bevelled, or stepped
teeth, moved by three, four, five, or more catches (made of steel or
other metal) mounted on a stud on the rocking lever may be used. Or
instead of the above arrangement of mechanism, when a weighted takeing-
up motion is required, we use a cranked weighted lever_ as usual, but
on the catch stud, instead of having a catch, we place one end of a
connecting rod, the other end of which goes on to a stud which
into
goes
a slot in a rocking lever which oscillates on the stud that carries the
ratchet wheel or pulley; on this lever is a stud on which is mounted the
catches or slide for moving the wheel or pulley. Above the cloth beam
and with one end resting on the cloth is a lever, in the other end of

page_text: which is a stud on which is hung a connecting rod, in the lower end of
which is a stud in which one end of the connecting rod that is fast to
the weighted lever goes. This stud also takes into the slot in the rocking
lever; by this means the cloth will be taken up at or near an uniform
tension, whether the cloth beam be full or empty.
SPECIFICATION filed in pursuance of the conditions of the Letters
Patent and of an Order of the Lord Chancellor, by the said Ellis
Butterworth and Matthew Hawksworth in the Great Seal Patent
Office on the 20th May 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ELLIS
BUTTERWORTH, of Calder Cottage, near Rochdale, and MATTHEW
HAWKSWORTH, of Number 6, Chester Street, Rochdale, both in the
County of Lancaster, send greeting.
.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of November, in the
year of our Lord One thousand eight hundred and seventy-one, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Ellis Butterworth and Matthew
Hawksworth Her special license that we, the said Ellis Butterworth
and Matthew Hawksworth, our executors, administrators, and assigns,
or such others as we, the said Ellis Butterworth and Matthew
Hawksworth, our executors, administrators, and assigns, should at any
time 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 In-
vention for “IMPROVELIENTS IN LOOKS FOR WEAVING," upon the condition
(amongst others) that we, the said Ellis Butterworth and Matthew
Hawksworth, our executors or administrators, by an instrument in
writing under our, or their, or one of their hands and seals, 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

page_text: rocking lever is moved so as to take up the cloth at or near a uniform
speed.
Instead of a pulley a ratchet wheel with straight, bevelled, or stepped
teeth moved by four, five, or more catches (made of steel or other metal)
mounted on a stud on a rocking lever may be used. Or, instead of the
above arrangement of mechanism, when a weighted taking-up motion is
required, we use a cranked weighted lever as usual, but on the catch
stud, instead of having a catch, we place one end of a connecting rod,
the other end of which goes on to a stud which goes into a slot in the
rocking lever, which lever and the other parts of the mechanism we
propose to have the same as mentioned before. By this means the cloth
will be taken up at or near a uniform tension, whether the cloth beam
be full or empty.
And in order that our Invention may be fully understood and readily
carried into operation, we will proceed to describe the accompanying
Sheet of Drawings, reference being had to the figures and letters marked
thereon.
Figure 1 shows one arrangement of our picking motion as applied to a
loom for weaving calicoes. a, is the lathe of the loom; b, parts of the
frame sides, care levers which, when the shuttle is required to be picked,
are depressed by bowls which are mounted on studs fast to the tappets
that work the healds when depressed; the levers c pull down the strap
d, the upper end of which are coiled round and fast to a boss of the
pulley e, thus causing it to move part of a revolution; f, is an endless
strap which passes round and is fastened to the pulley e, and passes over
the pulley g; and round the pulley h, to this strap is fastened the picker
or picker holder i. This picker or picker holder passes up through a slot
in the lathe from the bottom to the top of the lathe; k, are spiral
springs, one end of which are attached to the frame side, and the other
take hold of a strap which is fast to and coils round a boss of the
pulley e; thus these springs pull the picker back after it has made
its pick.
Figure 2 is a front, and 3, a side elevation of another arrangement of
the picking motion. a, are the frame sides; b, the lathe; c and c¹, the
picking treddles; d, a strap that is fast to the treddles, and goes
over and is fast to the boss of the pulley e, which is mounted loosely on

page_text: under the pulley e, and fast to it
strap 9, which passes over the
a stud f, which is fast to the lathe
passes the lower side of an endless
pullies h and h³, and round the pulleys i, to this strap are fastened the
pickers or picker holders; and ; thus, by depressing c or c¹ the shuttle
may be picked across the loom.
Figure 4 shows part of a loom with our improved taking-up motion
applied. a, is the loom side; b, the cloth roller on which the cloth is
wound after being woven; c, is a stud which is fast to the lathe sword,
and moves to-and-fro with it. This stud works in the slot of the
lever d, and causes it to oscilate on the stud e; on the top of this lever
is a stud f, which is taken hold of by the connecting rod g, the other end
of which takes hold of a stud h, which passes through the slot in the
rocking lever i, and is fast to the link j, the lower end of which goes on
to the stud k, which is fast to the slide 1, the top end of which rests on
the cloth on the cloth roller. The rocking lever i oscillates on the boss of
the pulley m, which is fast on the shaft n, which revolves in the boss of
the bracket o. On this shaft n is fastened a wheel which, through a
train of other wheels drives the cloth roller. On the lower end of the
rocking lever i is a stud, on which is mounted a slide or catch r, which
when the lever is going in one direction pushes the pulley part of a
revolution; 8, is a detaining slide or catch.
The action of the apparatus is as follows:-When the cloth roller is
empty the slide by means of the stud / and link ; pulls the stud h
which actuates the rocking lever down towards the centre on which the
rocking lever oscillates, and as the stud / always moves to-and-fro the
same distance it causes the rocking lever to oscillate more, and thereby
move the pulley m a greater part of a revolution, and thus turns the
cloth roller more than if the stud h was nearer the top of the slot; thus
if the cloth roller is empty, the slide 7 pushes the stud h near the centre
on which the rocking lever oscillates, and thereby turns the cloth roller
faster; and as the cloth beam fills the slide lifts the stud h higher in
the slot, and thereby turns the cloth roller slower, and thus the cloth
will be taken up at or near a uniform speed whatever diameter the
roller may be.
Figure 5 shows part of a ratchet wheel with straight teeth, and
Figure 6, catches of various lengths on one stud. This ratchet wheel
be used instead of the pulley m, Figure 4, and the catches instead
may

page_text: of the slides and 8; instead of the ratchet wheel having straight teeth
it might have bevilled or stepped teeth, when the catches might all be
of one length.
When a weighted taking-up motion is required, we propose to make
the lever d, see Figure 4, the same as the lever d, see Figure 6, in which
Figure c is the stud that is fast to the lathe sword, and moves the
leverd, and e are weights suspended to the lever d to pull round the
cloth roller.
Having now described the nature of the said Invention, and how it
may be carried into effect, we wish it to be understood that we do not
limit ourselves to the details herein set forth, but we claim,–
-
First. Picking shuttles in looms by means of bands passing over or
fastened to pulleys or segments of pulleys attached to the lathe, as shown
and described.
Secondly. Taking-up by means of a plate or pulley actuated sub-
stantially as described; or by a ratchet wheel with straight, bevilled, or
stepped teeth, which is actuated by four or more catches mounted on a
stud on the rocking lever, substantially as described.
In witness whereof, we, the said Ellis Butterworth and Matthew
Hawksworth, have hereunto set our hands and seals, this Eighth
day of May, in the year of our Lord One thousand eight
hundred and seventy-two.
