PROVISIONAL SPECIFICATION left by the said Edward Wadsworth
at the Office of the Commissioners of Patents, with his Petition, on
the 25th November 1862.
I, EDWARD WADSWORTH, of Macclesfield, in the County of Chester, and
of the Firm of John B. and Edward Wadsworth, Silk Manufacturers,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY USED IN THE MANUFACTURE OF CERTAIN DESCRIPTIONS OF BRAID,'
to be as follows:-
"
My improvements in braiding machinery are applicable to those machines
in which gut, india-rubber, or other thick threads are interwoven with or
covered by the braiding thread, and consist in effecting, the stoppage of the
braiding machinery by so arranging or connecting a lever or weight with such
thick or foundation threads that in the event of their becoming detached or
broken, or not forming one continuous thread from the supply spools or

page_text: bobbins to the manufactured braid, the said lever or weight shall come into
contact with any suitable arrangement of mechanism which may be designed
to stop the machinery, thus making the disunion of the thread stop the
machine by self-acting means, the arrangement of the mechanism I prefer
being as follows:-
Underneath the braiding spindles and in a convenient position between the
framing of the machine, a horizontal shaft is situated, and supplied with a
number of bent or bell-crank levers, each lever at its upper end having a small
bowl or pulley around which the gut. or india-rubber thread passes from the
supply spool to the manufactured braid, the opposite or lower end of the said
levers being slightly weighted and recessed at the extremity for the purpose
of fitting into a vibratory bar corresponding with such recess, the said vibratory
bar being placed immediately below the horizontal shaft supporting the before-
mentioned bent or bell-crank levers; the rise and fall or vibratory motion of
such bar being obtained through an arrangement of levers from a grooved cam
on an upright shaft deriving its motion from the driving shaft of the machine
through the medium of a clutch box, so that in the event of such clutch box
being disconnected the upright shaft is thrown out; of gear and so effects the
stonnage of the machine

Britain and Ireland, the Channel Islands; and Isle of Man, an Invention for
"IMPROVEMENTS IN MACHINERY, USED IN: THE MANUFACTURE OF CERTAIN
DESCRIPTIONS OF BRAID," upon the condition (amongst others) that I, the
said Edward Wadsworth, 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 immediately after the date of the said Letters Patent::
NOW KNOW YE, that I, the said Edward Wadsworth, do hereby
declare the nature of my said Invention, and in what manner the same is
to be performed, to be particularly, described and ascertained in and by the
following statement and accompanying Drawings (that is to say) :-
My improvement in braiding.machinery is applicable to those machines in
which gut, india-rubber, or other thick threads are interwoven with or covered
by the braiding thread, and consists in effecting the stoppage of the braiding
machinery by so, arranging or connecting a lever or weight with thick or
foundation threads that in the event of their becoming detached or broken,
or not forming one continuous thread from the supply spools or bobbins to
the manufactured braid, the said lever or weight shall come into contact
with any suitable arrangement of mechanism as may be designed to stop
the machinery, thus making the disunion of the thread stop the machine
by self-acting means, the arrangement of the mechanism I prefer being as
follows: 1
2 W
.
a
Underneath the braiding spindles and: in a convenient position between
the framing of the machine, a horizontál shaft is situated, and supplied with a
number of bent or bell-crank levers, each lever at its upper end having
small bowl or pulley, around which the gut or india-rubber thread passes.
from the supply spool to: the manufacturéd braid; the opposite or lower end
of the said levers being slightly weighted and recessed at the extremity for
the purpose of fitting into a vibratory bar corresponding with such recess,
the said vibratory bar being placed immediately below the horizontal shaft
supporting the before-mentioned bent or bell-crank levers, the rise and fall or
vibratory motion of such bar being obtained: (through an arrangement of levers
from a grooved cam on an upright shaft,..sucht shaft deriving its motion from
he driving shaft of the machine through the medium of the clutch box, so that'
n the event of such clutch box being disconnected the upright shaft is thrown
out of
gear,
and so effects the stoppage of the machine.

page_text: In order that the Invention may be better understood and explained in
detail, I have hereunto attached a Sheet of Drawings made upon a scale of
about three inches to the foot, similar letters of reference being marked upon
corresponding parts.
Fig. 1 being a side elevation of part of a braiding machine as employed
for such purposes, having any improvements attached; Fig. 2 is an end view
of the same; Fig. 3 is a plan view shewing the stop circle and lever, and
Fig. 4 is a detached view shewing the spools and levers, the latter being in a
vertical position as when effecting the stoppage of the machine.
That the effect of the several parts may be more readily understood, I will
proceed to describe their movements and action; let it be supposed that the
manufacture of braid is proceeding, and the gut or elastic a, shewn in red,
is in one continuous length between the supply spools and the braid into
which it is being woven, the tension of the gut at such times. passing
underneath the bowl or pulley c on the bent or bell crank lever d will cause
the lower portion of such lever d' on the opposite side of its fulcrum or
horizontal shaft to be in a diagonal position to such shaft, as seen in Fig. 1,
thereby allowing a free swing or vibratory motion to the bar e immediately
beneath, but as soon as the gut or elastic becomes. disconnected or broken
between the spool and the braid the small bowl or pulley on the upper end
of the bell-crank lever is no longer retained thereby, consequently the weighted
or opposite end of such lever immediately assumes a vertical position under-
neath the horizontal shaft f, as in Fig. 4, and forms a stop or impediment to
the vibratory bar, and so causes the fulcrum 9 of the lever h, in connecting
with the grooved cam i, to yield or rise, which said action displaces a finger k
from a recess or notch on the rod l, which is in connection with the ordinary
stop circle m, and so allows of the free upward action of the spring n, which
is connected to the clutch box, and which thereby throws it out of gear,
effectually stopping the machine. When it is required to set the machine
in motion, the shaft or rod o is to be turned by the handle p, which depresses
the spring n to its former position and replaces the clutch box in gear. The
driving of the machine is effected by the shaft q and bevel wheels r, which give
motion to the clutch box.
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 the employment and use of self-acting mechanism for
effecting the stoppage of braiding machines wherein india-rubber or gut or
other thick threads are covered by and interwoven with the braiding threads,

page_text: either by a mechanical equivalent which depends upon the disunion or
absence of the said thicker threads to effect such stoppage, or by the
arrangement and combination of mechanism as herein-before described, set
fortb, and fully illustrated in the Drawings attached.
In witness whereof, I, the said Edward Wadsworth, have hereunto
set my hand and seal, this Twenty-second day of May, in the year
of our Lord One thousand eight hundred and sixty-three.
EDWARD WADSWORTH. (L.B.)
