CERTAIN IMPROVE- IN BRAIDING MACHINES
Year: 1864

page_text: LETTERS PATENT to Theophilus Jackson, of Manchester, in the County
of Lancaster, Manufacturer, for the Invention of "CERTAIN IMPROVE-
IN BRAIDING MACHINES."-A communication from abroad by
Thomas James Sloan of Paris in the Empire of France. Engineer.
Sealed the 12th April 1864, and dated the 18th February 1864.
PROVISIONAL SPECIFICATION left by the said Theophilus Jackson at
the Office of the Commissioners of Patents, with his Petition, on the
18th February 1864.
I, THEOPHILUS JACKSON, of Manchester, in the County of Lancaster, Manu-
facturer, do hereby declare the nature of the said Invention for "CERTAIN
IMPROVEMENTS IN BRAIDING MACHINES," (being a communication to me from
abroad by Thomas James Sloan, of Paris, in the Empire of France, Engineer,)
to be as follows:-
My Invention relates to further improvements upon a certain description of
braiding machines for which Letters Patent were granted to John Henry
Johnson, dated October 18, 1861, No. 2604, and the present improvements
consist, first, in the employment and use of a helical spring enclosed within a
small cylinder at the top of the "braiding spindle" acting upon a bent wire
or "dropper" so as to force it down into the notches formed in the top of the
bobbin. This spring is retained from forcing down the "dropper" by means
of the yarn or thread from the bobbin when such remains entire, but in the

page_text: absence or in the disunion of the thread the spring is released and the
dropper" is forced into the notches and prevents the revolution of the bobbin
and the delivery of the thread.
A second portion of the Invention consists in the application and use of
twisted and curled (wire (similar to those used at the extremities of flyers) 5
as a substitute for the eyelet holes now employed to guide the yarn, by the
use of which curled wire the operation of threading the yarn is facilitated and
an economy of time is effected.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Theophilus Jackson in the Great Seal Patent Office on the
18th August 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THEOPHILUS
JACKSON, of Manchester, in the County of Lancaster, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of February, in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-seventh
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Theophilus Jackson, Her special license that I, the
said Theophilus Jackson, my executors, administrators, and assigns, or such
others as I, the said Theophilus Jackson, 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 Invention for "CERTAIN IMPROVEMENTS IN BRAIDING MACHINES,"
being a communication to me from abroad by Thomas James Sloan, of Paris,
in the Empire of France, Engineer, upon the condition (amongst others) that. I,
the said Theophilus Jackson, my executors or administrators, by an instru-
ment in writing under my, 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 months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Theophilus Jackson, do hereby declare
the nature of the said Invention, and in what manner the same is to be

page_text: performed, to be particularly described and ascertained in and by the
following statement and accompanying Drawings (that is to say) :-
My Invention relates to further improvements upon a certain description of
braiding machines for which Letters Patent were granted to John Henry
Johnson, dated October 18, 1861, No. 2604, and the present improvements
consist, first, in the employment and use of a helical spring enclosed within a
small cylinder at the top of the "braiding spindle" acting upon a bent wire
or "dropper," so as to force it down into the notches formed on the top of
the bobbin; this spring is retained from forcing down the "dropper" by
means of the yarn or thread from the bobbin when such remains entire, but
in the absence or in the disunion of the thread the spring is released, and the
dropper" is forced into the notches, and prevents the revolution of the
bobbin and the delivery of the thread.
A second portion of the Invention consists in the application and use of
twisted or curled wire (similar to that used at the extremities of "flyers") as
a substitute for the eyelet holes now employed to guide the yarn, by the use of
which curled wire the operation of threading the yarn is facilitated and an
economy of time is effected.
In order that the Invention may be better understood and explained in
detail, I have hereunto attached a Sheet of Drawings made about the
full size.
Fig. 1 represents a vertical sectional view of the braiding spindle employed
in the description of braiding machines aforesaid, shewing the spring acting
upon the bent wire or "dropper," and also the curved wire or "twirl" applied
to the "stop wire" and guide to facilitate the threading of the yarn; Fig. 2
is a plan view of the same.
In Fig. 1 a, a, is the tube or portion of the spindle enclosing the spring b,
which presses the "dropper" c on the top of the bobbin to effect its
stoppage in the event of a thread breaking. The "dropper" is formed of a
piece of wire, bent as shewn, one end being acted upon by the spring, the
other encircling the outside of the tube, which ensures steady and vertical
movement. The curled wire e is similar to that now employed on "flyers"
for spinning cotton, and is here adapted instead of the usual eyelet holes on
the guide and the "stop wire" 9, and are employed to effect an economy
in time.
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, I wish it to be distinctly
understood that I claim.-

page_text: The application and use of a helical or other convenient spring to act upon
the "dropper."
And, secondly, the adaptation of the curved wire or twirl to the guide and
stop wire instead of the usual eyelet.
In witness whereof, I, the said Theophilus Jackson, have hereunto set
my hand and seal, this Eleventh day of August, in the year of our
Lord One thousand eight hundred and sixty-four.
