$6 IMPROVEMENTS IN BRAIDING MACHINES."
Sealed the 25th September 1868, and dated the 2nd April 1868.
PROVISIONAL SPECIFICATION left by the said Andrew Jackson and
John Hartley at the Office of the Commissioners of Patents, with
their Petition, on the 2nd April 1868.
We, ANDREW JACKSON, of the City of Manchester, in the County of
Lancaster, Braid Manufacturer, and JOHN HARTLEY, of the same Place,
Foreman Mechanic, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN BRAIDING MACHINES," to be as follows:-
This Invention consists in improved mechanism for giving revolving
motion to the carriers. Instead of employing a small centre wheel on
the centre stud gearing into intermediate wheels which gear into the
driving carrier wheels we fix on the centre stud a bevil wheel into
which is geared a bevil pinion fixed to the driving shaft of the machine

page_text: and below the bevil wheel is fixed a large crown or centre wheel gearing
into long pinions fixed on every other carrier, which pinions gear into
shorter pinions on the other carriers, the long pinions being for the
purpose of enabling the shorter pinions to gear with them and yet be
out of gear with the large crown wheel so that the carriers having the
longer pinions shall turn in one direction and those with the shorter
pinions in the opposite direction, which arrangement enables the spindle
to have a steadier motion than before attained, and the loss of time
which frequently occurs with the old machines from the slipping of the
driving carrier wheels and consequent twisting of the head is altogether
avoided.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Andrew Jackson and John Hartley in the Great
Seal Patent Office on the 2nd October 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ANDREW
JACKSON, of the City of Manchester, in the County of Lancaster, Braid
Manufacturer, and JOHN HARTLEY, of the same Place, Foreman
Mechanic, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of April, in the year
of our Lord One thousand eight hundred and sixty-eight, in the
thirty-first year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Andrew Jackson and John Hartley,
Her special license that we, the said Andrew Jackson and John
Hartley, our executors, administrators, and assigns, or such others as
we, the said Andrew Jackson and John Hartley, 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 Invention for "IMPROVEMENTS IN
BRAIDING MACHINES," upon the condition (amongst others) that we, the said
Andrew Jackson and John Hartley, our executors or administrators, by
an instrument in writing under our, or their, or one of our or their hands
and seals, should particularly describe and ascertain the nature of the

page_text: 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.
KNOW NOW YE, that we, the said Andrew Jackson, and John
Hartley, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the folowing statement (that is to say) :-
:-
This Invention consists in improved mechanism for giving revolving
motion to the carriers. Instead of employing a small centre wheel on
the centre stud gearing into intermediate wheels which gear into the
driving carrier wheels we place loose on the centre stud a bevil wheel
into which is geared a bevil pinion fixed to the driving shaft of the
machine and below the bevil wheel is placed loose a large crown.or
centre wheel gearing into long pinions fixed on every other carrier,
which pinions gear into shorter pinions on the other carriers, the long
pinions being for the purpose of enabling the shorter pinions to gear
with them and yet be out of gear with the large crown wheel so that
the carriers having the longer pinions, shall turn in one direction and
those with the shorter pinions in the opposite direction, which arrange-
ment enables the spindles to. have a steadier motion than before attained,
and the loss of time which frequently occurs with the old machines
from the slipping of the driving carrier wheels and consequent twisting
of the head is altogether avoided.
This Invention will be clearly understood by referring to the Figures
and letters on the accompanying Sheet of Drawings, in which Figure 1
is an elevation, and Figure 2 a vertical section of the lower part of a
braiding machine provided with our improvements; Figure 3 is a
sectional plan of Figure 1 at the line A, B, and Figure 4 a sectional plan
of Figure 2 at the line C, D.
a represents part of the framework of the machine; b, the lower
parts of the carriers; c, the driving shaft, and d, the fast and loose
pulleys. To the bottom footstep plate e is. fixed the ordinary centre
stud fon which is placed loose the large crown wheel g and also the
bevil wheel h which gears into the bevil pinion i on the driving shaft c.
The large crown wheel g gears into the long pinions k on every other
carrier, the long pinions gearing into shorter pinions on the other
carriers. In connection with the crown wheel g and bevil wheel h there

page_text: is an ordinary catch m for enabling them to be independent of each other
or be held together, and when the driving strap is on the fast pulley
and the wheels not held together the bevil wheel turns loose on the
centre stud and the crown wheel is stationary, but when the wheels are
held altogether the crown wheel turns with the bevil wheel and turns
the longer pinions and the carriers to which they are fixed in one
direction, the longer pinions at the same time turning the shorter
pinions and carriers to which they are fixed in the opposite direction.
Having now described the nature and particulars of our said Inven-
tion and the manner in which the same is to be performed, we desire
it to be understood that we claim in braiding machines the bevil wheel
and large crown wheel on the centre stud in connection with the
longer and shorter pinions for enabling every other carrier to be turned
in one direction and the other carriers in opposite directions as all such
improvements are herein described and illustrated on the accompanying
Sheet of Drawings.
In witness whereof, I, the said Andrew Jackson, for and on behalf
of myself and the said John Hartley, have hereunto set my
hand and seal, this First day of October, in the year of our Lord
One thousand eight hundred and sixty-eight.
Signed, sealed, and delivered by
the within-named Andrew
Jackson, in the presence of
