Year: 1861

page_text: LETTERS PATENT to Henry Bernoulli Barlow, of the City of Manchester,
Patent Agent, for the Invention of "CERTAIN IMPROVEMENTS IN MACHINERY
FOR SPINNING."-A communication from abroad by Messieurs Jules
Harmel, Leon Harmel, and Ernest Harmel, of Paris, in the Empire of
France, Spinners.
Sealed the 5th November 1861, and dated the 3rd July 1861.
PROVISIONAL SPECIFICATION left by the said Henry Bernoulli Barlow
at the Office of the Commissioners of Patents, with his Petition; on the
3rd July 1861.
I, HENRY BERNOULLI BARLOW, of the City of Manchester, Patent Agent,
do hereby declare the nature of the said Invention for "CERTAIN IMPROVEMENTS
IN MACHINERY FOR SPINNING," a communication to me from abroad by Messieurs
Jules Harmel, Leon Harmel, and Ernest Harmel, of Paris, in the Empire of
France, Spinners, to be as follows:-
These improvements are more particularly applicable for spinning wool and
other animal fibres. The Invention consists,-
First, in imparting a variable speed to the carriage of the spinning machine,
which speed can be modified according to the nature and quality of the
fibres.
Secondly, in performing the two operations of roving, or coarse spinning
and fine, spinning in the same machine, thereby economising time and

page_text: obtaining the same result as has heretofore been produced by two separate
operations.
Thirdly, the application of self-acting mechanism to machinery for spinning
carded wool or other animal fibres, by which the running in of the carriage,
the backing off, the winding on, and the other motions required to render the
machine self-acting are effected.
And, fourthly, the application of differential motion to the spindles while
the twist is being given to the yarn.
The machinery for effecting the operations above referred to consists of a
friction disc, on the face of which two friction pulleys operate; one of these
pulleys is for driving the spindles while the twist is given to the yarn, and the
other gives the requisite variable motion to the carriage; both these pulleys
are actuated by inclined planes, cams, or eccentrics, or cones may be used
instead of the friction disc and pulleys above described.
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 31st December 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
BERNOULLI BARLOW, of the City of Manchester, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of July, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Henry Bernoulli Barlow, Her special licence that I, the said Henry
Bernoulli Barlow, my executors, administrators, and assigns, or such others
as I, 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 Isle of Man, an Inven-
tion for "CERTAIN IMPROVEMENTS IN MACHINERY FOR SPINNING," a communica-
tion to me from abroad by Messieurs Jules Harmel, Leon Harmel, and
Ernest Harmel, of Paris, in the Empire of France, Spinners, upon the con-
dition (amongst others) that I, the said Henry Bernoulli Barlow, my executors
or administrators, by an instrument in writing under my, or their, or one of
their hands and seals, should particularly describe and ascertain the nature of

page_text: 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.
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 ascertained in and by the
following statement, that is to say) :-
These improvements are more particularly applicable for spinning wool and
other animal fibres. The Invention consists,-
First, in certain improved combinations of machinery for imparting a
variable speed to the carriage of the spinning machine, which speed can be
modified according to the nature and quality of the fibres to be spun.
Secondly, the performing the two operations of roving or coarse spinning
and fine spinning in the same machine, thereby economizing time and
obtaining the same result as has heretofore been produced by two separate
operations.
Thirdly, the application of self-acting mechanism to machinery for spinning
carded wool or other animal fibres, by which the running in of the carriage,
the backing off, the winding-on, and the other motions required to render the
machine self-acting are effected.
And, fourthly, the application of differential or variable motion to the
spindles while the twist is being given to the yarn.
And in order that this Invention may be fully understood and readily carried
into effect, I will proceed to describe the accompanying Sheet of Drawings,
reference being had to the figures and letters marked thereon.
Figure 1 is an elevation of part of the headstock of a mule for spinning
wool, to which my improvements are applied; Figure 2 is a plan of the same;
and Figure 3 is a detached view of the excentric W.
A is the driving shaft, which by a pair of bevel wheels gives motion to the
vertical shaft A', to which is fixed the friction disc B; C is a friction disc for
driving the spindles while the twist is given; this disc slides on the shaft C',
to which is fixed the twist pulley D. F is the friction disc for giving motion
to the carriage of the mule while it is running out; the disc F is loose on the
shaft F; both the discs C and F are moved to and fro on their shafts by the
cams R, which have inclined planes on their edges, so as to bring them nearer
to or further from the centre of the disc B, thereby varying their velocity; the
cams R act on levers S, which are forked at one end and have studs taking
into grooves in the bosses of the discs C and F.

page_text: -Instead of the cams R, eccentrics similar to that shewn at W, Figure 3,
may be employed.
By means of the improved combination of machinery above described, the
following operations are performed,-
First, the requisite variable speed is given to the carriage of the mule,
according to the quality and condition of the fibrous materials under operation,
which speed is governed by an inclined plane or an eccentric.
Secondly, the combining in a single machine the two operations of roving or
coarse spinning and fine spinning, with the same preparatory operations as
hitherto required for the distinct operations.
Thirdly, the application of self-acting machinery to spinning machines for
carded wool.
And, fourthly, the application of a variable motion to the spindles of spinning
machines during the twist, whether such motion is produced in the manner
above described or by eccentrics, or horizontal or vertical axes.
Having thus described the nature of the Invention, as communicated to me,
and the manner of performing the same, I declare that I claim the friction
disc B and the friction pulleys C and F, with the parts acting in combination
therewith, when used in the manner and for the purposes described.
In witness whereof, I, the said Henry Bernoulli Barlow, have hereunto
set my hand and seal, this Twenty-eighth day of December, in the year
of our Lord One thousand eight hundred and sixty-one.
H. B. BARLOW. (L.S.)
