the County of Lancaster, Consulting Engineer and Patent Agent,
for the Invention of "IMPROVEMENTS IN MACHINERY FOR SPINNING,
DOUBLING, AND TWISTING COTTON AND OTHER FIBROUS SUBSTANCES."-
A communication.
Sealed the 28th November 1853, and dated the 9th June 1853.
PROVISIONAL SPECIFICATION left by the said Henry Bernoulli
Barlow at the Office of the Commissioners of Patents, with his
Petition, on the 9th June 1853.
I, HENRY BERNOULLI BARLOW, of Manchester, in the County of Lan-
caster, Consulting Engineer and Patent Agent, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR
SPINNING, DOUBLING, AND TWISTING COTTON AND OTHER FIBROUS SUBSTANCES,"
to be as follows:-
My Invention consists in an improved combination of parts forming
a spindle and flyer and copping rail for throstles or other machines of
the like nature used in spinning, doubling, and twisting. The spindle
rail is stationery, and to it the spindles are fixed; the wharves fit

page_text: loosely on the spindles, and they are furnished with octagon or other
suitably shaped bosses, so that the flyers, which are provided below with
a round plate and above with an inverted footstep, fitting on the top of
the spindle, may be taken round with the wharf. The bobbin on
which the yarn or thread is wound is provided with a bush, fitting on
the spindle, and the bottom of the bobbin is supported by the plate
connecting the legs of the flyer.
The amount of friction given to the bobbin can be adjusted by increas-
ing or diminishing the amount of bearing surface between the bottom of
the bobbin and the upper surface of the plate on which it is supported.
The yarn or thread is guided through a wire loop on the top of the
flyer, and then through one or two loops attached to a circular plate,
which is slidden up and down the legs of the flyer, and revolves with
the flyer. The up and down motion is given to the plates with the
loops by pins projecting from a rail or rails, actuated in the same
manner as the copping rails of ordinary throstles.
The above-described spindle and flyer is particularly applicable for
spinning.
Another of my improvements consist in a new combination of parts
forming a spindle and bobbin particularly applicable for twisting and
doubling silk; the spindles in this case are stationary, as before de-
scribed; the wharf fits on the spindle, and the bobbin fits on the boss
of the wharf, being carried round with it by a pin; the upper end of
the bobbin has a bush which fits on the spindle, to the upper end of
which is fixed a cap, somewhat larger in diameter than the bobbin. The
tension on the yard or thread to be twisted or doubled is given by the
said cap, around which it is drawn as the bobbin revolves.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Bernoulli Barlow in the Great Seal Patent
Office, on the 9th December 1853.

page_text: WHEREAS, in consequence of a communication made to me by a
foreigner residing abroad, I became and am in possession of an Inven-
tion for IMPROVEMENTS IN MACHINERY FOR SPINNING, DOUBLING, AND
TWISTING COTTON AND OTHER FIBROUS SUBSTANCES:" AND WHEREAS
Her most Excellent Majesty Queen Victoria, by Her Letters Patent,
bearing date the Ninth day of June, in the year of our Lord One thou-
sand eight hundred and fifty-three, in the sixteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said Henry Bernoulli Barlow, Her special license that I, the said
Henry Bernoulli Barlow, my executors, administrators, and assigns,
or such others as J, the said Henry Bernoulli Barlow, my 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 the Isle of Man, the said Invention for "IMPROVE-
MENTS IN MACHINERY FOR SPINNING, DOUBLING, AND TWISTING COTTON AND
OTHER FIBROUS SUBSTANCES," upon the condition (amongst others) that
I, the said Henry Bernoulli Barlow, by an instrument in writing under
my hand and seal, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be per-
formed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said Henry Bernoulli Barlow, do
hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascer-
tained in and by the following statement, that is to say:
The Invention consists, first, in an improved combination of parts
particularly applicable to the machines for spinning, called throstles;
these improvements relate to the bobbin on which the yarn is wound,
and to the parts in connection therewith. And, secondly, in an im-
proved bobbin, and parts in connection therewith, particularly applicable
to machines for doubling and twisting silk; and in order that the
Invention may be fully understood, and readily carried into effect, I will

page_text: DESCRIPTION OF THE DRAWING.
Fig. 1, represents a transverse section of the improved spindle and
parts in connection therewith; Fig. 2, is an elevation of the same; Fig.
3, is a plan of Figs. 1, and 2; Figs. 4, and 5, are two views of the rails
by which the yarn guide is moved up and down the flyer; Fig. 6, is a plan
of part of the flyer, and of the wharf by which it is driven; Fig. 7, is a
plan of part of the flyer; Fig. 8, is a side elevation of the yarn
guide; Fig. 9, a plan, and Fig. 10, a section of the same; Fig. 11, is
a section of the wharf taken through the line a, a, on Fig. 12, which is
a plan of the same; Fig. 13, is another section of the wharf, taken
through the line 2, 2, on Fig. 12; and Fig. 14, represents an elevation
of all the above-mentioned parts put together. In Figs. 1, 2, and 14,
a, a, are the spindles, which are stationary and secured into the cross
rails; n, n, arc the wharves fitting on the spindles, and put in motion
in the ordinary manner by a band from the driving drum. The bosses
on the wharves are flattened on four sides, as seen in Figs. 6, and 12,
in order that the motion imparted to then by the driving band may be
communicated to the flyer g, the legs of which are rivetted into the
plate p, which is furnished with a round hole in the centre, and a key
at one side, fitting the flattend side of the boss of the wharf, as
seen in Figs. 6, and 7. The flyers g, are supported above by the top of
the spindle, as seen in Fig. 1. The bobbins b, b, are provided with metal
tubes h; and the under side of the bobbin, which bears upon the plate p,
is levelled off, as shewn in the Drawings. By increasing or diminishing
the amount of contact between the plate p, and the under side of the
bobbin the tension or drag upon the yarn can be regulated. The plates
y, y, which are shewn detached in Figs. 8, 9, and 10, are furnished with
guides fitting on the legs of the flyers g, g, and these plates are moved
up and down in order to distribute the yarn on the bobbin by the
pins i, i, projecting from the rails k, and , the upward and downward
motion of which is produced in the ordinary way for giving motion to

page_text: the copping rails of throstles. When the bobbins are full the upper
rail k, is moved endways in the direction of the arrow in Fig. 4, so as to
bring the upper pins i, beyond the plate y; the attendant can then raise
the flyer g. off the spindle a, and with it the plate y, and the full bobbin,
which is then removed, and an empty one put in its place. In Fig.
14, A, is the front drawing roller; the dotted line represents the yarn
which passes through the loop g', fixed on the top of the flyer g; it is
then conveyed round both of the loops y', attached to the plate y;
from whence it goes to the bobbin b. The advantages obtained by this
mode of construction are, first, increased security at great velocity;
secondly, the amount of twist can be regulated so as to spin either weft
or fine numbers of twist; and, thirdly, a considerable saving in the
motive power, as the plate p, which can be made lighter or heavier,
acts as a fly wheel, and assists in carrying the flyer round.
In Figures 15, and 16, I have shewn the improvements applicable to
machinery for doubling and twisting silk; in these views t, is the
spindle, fixed in the traverse 1; e, is the wharf, fitting loose on the
spindle, and put in motion by a band from the driving drum in the
usual manner; f, is the bobbin, which is carried round with the wharf
by the pin e', shewn in Fig. 16. The bobbin is provided above with a
bush v, fitting on the spindlet; to the upper part of which is also fitted
the cap ; this cap does not revolve, but it can easily be removed
when the full bobbin has to be replaced by an empty one. The requisite
tension for winding the yarn or thread on to the bobbin is produced by
the friction of the yarn or thread passing over the cap q, the diameter of
which can be increased or diminished when more or less tension is
required.
Having now described the nature of the Invention, and the best
means communicated to me for carrying the same into effect, I wish it
to be understood that I do not limit myself to the details hercin set
forth, as the same may be varied without departing from the peculiar
character of the Invention. I would also observe, that I do not claim
any of the parts taken separately; but what I do claim is,―
First, the improved combination of parts above described, and

page_text: referred to in Figures 1, to 14, for spinning cotton and other fibrous
substances; and,
Secondly, the improved combination of parts above described, and
referred to in Figures 15, and 16, for twisting and doubling.
In witness whereof, I, the said Henry Bernoulli Barlow, have
hereunto set my hand and seal, this Eighth day of December,
One thousand eight hundred and fifty-three.
