Year: 1832

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
BROWN, of Heaton Norris, in the County of Lancaster, Cotton Manufacturer;
and THOMAS HEYS, of Heaton Norris aforesaid, Book-keeper, send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by Ilis Letters Patent under the Great Seal of Great Britain, bearing
date at Westminster, the Eighth day of September, in the third year of His
reign, did, for Himself, His heirs and successors, give and grant unto us,
the said John Brown and Thomas Heys, our exors, admors, and assigns, or
such others as we, the said John Brown and Thomas Heys, our exors, admors,
or assigns, should at any time agree with, and no others, from time to time
and at all times during the term of years therein expressed, should and
lawfully might make, use, exercise, and vend, within England, Wales, and
the Town of Berwick-upon-Tweed, our Invention of "AN IMPROVEMENT IN
THE MACHINERY USED FOR SPINNING COTTON, SILK, FLAX, AND OTHER FIBROUS
SUBSTANCES COMMONLY CALLED THROSTLES;" in which said Letters Patent is
contained a proviso obliging us, the said John Brown and Thomas Heys, by an
instrument in writing under our hands and seals, particularly to describe and
ascertain the nature of our said Invention, and in what manner the same
is to be performed, and to cause the same to be inrolled in His said
Majesty's High Court of Chancery within two calendar months next and
immediately after the date of the said recited Letters Patent, as in and by
the same, reference being thereunto had, will more fully and at large appear.

page_text: Invention to consist of an improved method of causing the bobbin of the
throstle to move up and down for the purpose of having distributed on it the
yarn, and for preventing the vibration and decreasing the friction of the
spindle; and in further compliance with the said proviso, we, the said John
Brown and Thomas Heys, do hereby describe the manner in which our said
Invention is to be performed, by the following description thereof, reference
being had to the Drawing annexed, and to the figures and letters marked
thereon; that is to say:-
DESCRIPTION OF THE DRAWING.
Figure 1 represents a front view, and Figure 2 a side view of a portion
of the throstle frame. A is a lifting plate for the purpose of lifting the
bobbin, and it and the spindle rail B, keep the spindles fixed in their proper
stations. The plate A and the rail B are made of similar strength and
dimensions as the common throstle plates and rails, or may be varied
according to the work for which they are required. c is the spindle which
may be of similar length and strength to the common spindle, or varied
according to the work for which it is required, and in common throstles may
be made much thinner and lighter than those now in use; it is connected with
the tin roller in the usual way, by a pulley and string, or list. The top and]
bottom parts of the spindle e, e, e, e, must be made or turned so as just to
allow the lifting plate.A, the spindle rail B, and the bobbin b, b, b, b, to move
up and down the spindle, such spindle remaining stationary, except as to its
rotatory motion. C is the bottom spindle rail, in which are the usual steps,
made of brass or other metal, f. f,f,f, for the foot of the spindle to rest on.
These steps are made flat at the bottom, on which the spindle rests, to allow
the spindle to find it's own centre, and to save friction. In the lifting plate
A, and spindle rail B, are brass bolsters g, g, g, g, for the spindle to run
in; these confine the spindles tight, in order to prevent vibration, and yet not
so tight as to prevent the lifting plate A, and the spindle rail B, moving up
and down the spindle in the direction e, e, e, e. The bolsters are secured in
the lifting plate and spindle rail by set screws or other fastenings. The
lifting plate A, on which the bobbin rests, is covered with cloth or leather
in the usual manner; in order to retard the speed of the bobbin, and enable
it to take up the yarn. This lifting plate A is connected firmly with the
spindle rail B, by iron pillars E, of which there must be more or less,
according to the length of the throstle. The lifting plate A, and the spindle

page_text: rail B, are moved up and down the spindles by the sliding rods F, one of
which rods is placed between every ténth spindle, or at a greater or less
distance, according to the usual manner. of placing lifting rods in throstles.
This lifting rod is connected with the lifting shaft D, in the usual manner, by
an iron plate W, and by a chain and screw x, or other fastening. The rod
F slides parallel with the spindles through the bottom rail C, and lifts the
lifting plate A, and the spindle rail B, up and down. The bobbins b, b, b, b,
rest in the usual manner on the lifting plate A, and move up and down with
the lifting plate A, and the spindle rail B, within the flyer, as in the old
plan or principle, whereby the yarn is distributed on the bobbins. By these
means the lifting plate A is made to answer more efficiently all the purposes
for which in the old throstle the top spindle rail and lifting plate were
required. The advantages to be derived from this improvement are:
First, the spindle will last longer, as the wear will, by reason of the lifting
plate A and the spindle rail B, being firmly connected together, and moving
up and down the sides of the spindle, be distributed over a greater portion of
the spindle, instead of all being on one place, as in the old plan.
Secondly, the bobbin being always close to the lifting plate A, and moving
up and down with it, has a constant support.
Thirdly, the speed of the spindle may, when necessary,
much.
be accelerated very
Fourthly, the spindle may be made much thinner, and there will, conse-
quently, be less friction than by the usual plan or principle, whereby a saving
of power will arise; and,
Fifthly, there will be a less waste of oil, as by applying a sponge, wet with
oil, to any portion of the spindle traversed by the lifting plate and spindle rail,
their motion up and down will distribute the oil more economically than in
the old plan or principle, which was by dropping oil into the bolster.
Now, whereas we claim as our Invention the following improvement, that
is to say, causing the lifting plate A alone to answer the purposes for
which in the old throstles the top spindle rail and lifting plate together were
required, by firmly connecting it with the spindle rail B, and causing both
the lifting plate A, and the spindle rail B, closely fitted as aforesaid to the
spindles, to move up and down the spindles, whereby the bobbin is moved up
and down, as in the old plan or principle, within the flyer, without the
inconveniences usually attendant on this movement; and such our Invention
being, to the best of our knowledge and belief, entirely new, and never before
used within that part of His said Majesty's United Kingdom of Great Britain
and Ireland called England, His said Dominion of Wales, or Town of Berwick-

page_text: upon-Tweed, we do hereby declare this to be our Specification of the same, and
that we do verily believe this our said Specification doth comply in all respects
fully, and without reserve or disguise, with the proviso in the said herein-
before in part recited Letters Patent contained; wherefore we do hereby
claim to maintain exclusive right and privilege to our said Invention.
In witness whereof, we, the said John Brown and Thomas Heys, have
hereunto set and put our hands and seals, the Fifth day of November,
One thousand eight hundred and thirty-two.
