page_text: I, EDWIN TRAFFORD, of London Mills, London Street, Leek, in the county of
Staffordshire, Silk Manufacturer, do hereby declare the nature of my invention
for "IMPROVEMENTS IN
WINDING ON SPOOLS DEFINITE LENGTOS
SEWING SILK TWIST, to be as follows:-
OF TAILORS'
On a very large bobbin (A in the accompanying drawing in duplicate) placed on
a horizontal spindle supported by the stand C, upon which spindle it is free to
revolve, there is wrapped a large quantity of the silk twist which has to be wound
on spools.
This silk twist, for tailors' use, has to be wound on spools in several threads
(varying in number according to the order of the buyer) running together, and
therefore on the large bobbin several threads of silk twist running together are
wrapped in one continuous length before the machine which I wish to patent
is used.
B is an iron bar hinged at one end on to the stand C, and the other end resting
on the edge of the large bobbin A prevents the bobbin turning by its own impetus,
and thus unwinding its silk twist on to the floor or table.
The several threads of silk twist running together are drawn off from the large
bobbin A, causing its revolution, by being wound on to the spool D, which is made
to revolve by being fixed on a spindle turned by the hand-wheel and strap E.
The silk twist in its passage from the large bobbin A to the spool D is made to
pass round the wheel F which it causes to revolve, and it is by means of this
wheel F and the apparatus with which it is connected by the shaft running
through its axis and which supports it in its revolution, that the silk wound on to
the spool D is measured.
The distance round the wheel F is exactly 36 inches, or in other words the
distance from the edge G of any one of the six light portions which project from
its axis to the edge of that next to it is exactly six inches-Each of these
projecting portions is very light, and they are made of thin wood except that
marked H in the drawing which is made of thin iron, and is made in two parts,
one fixed to the axis and the other movable, so that it may be lengthened by
drawing out the movable part which can be fixed to the desired length by means
of a small screw shown in the drawing. The reason why provision is made for

page_text: lengthening the projecting portion H is that it is sometimes desired to increase the
distance round the wheel F to somewhat more than 36 inches.
Every complete revolution made by the wheel F causes the teeth wheel I to
revolve the distance of the space occupied by one of its teeth, and thus when the
teeth wheel I has made one revolution the number of its teeth is the same as the
number of revolutions made by the wheel F, and, therefore, the number of yards
of silk twist wound on the spool D. And before the machine is started with the
spool D empty, the teeth wheel I is placed so that the peg K which is fixed to it
has the end of the light iron bar L resting upon it, and when on working the
machine by turning the hand-wheel E the peg K again comes in contact with
the light iron bar L, we are told that the teeth wheel I has made exactly one
revolution.
Therefore by using teeth wheels like I having the requisite number of teeth we
can measure accurately on to the spool D whatever number of yards of silk twist
we wish.
If it is wished to increase very slightly the length of silk twist wound on to
the spool D without changing the teeth-wheel I recoure is had to increasing
the length of the projecting portion H until the distances between its edge and the
edge of the light wooden projecting portion on each side of it are increased to the
requisite extent abovo six inches, and these two increases taken together give
the increase per yard of silk twist wound on to the spool D).

page_text: I, EDWIN TRAFFORD, of London Mills, London Street, Leek, in the County of
Staffordshire, Silk Manufacturer do hereby declare the nature of my invention
for IMPROVEMENTS IN WINDING ON SPOOLS DEFINITE LENGTHS OF TAILORS'
SEWING SILK TWIST and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
On a very large bobbin (A in the accompanying drawing in duplicate) placed on
a horizontal spindle, supported by the stand C, upon which spindle it is free to
revolve, there is wrapped a large quantity of the silk twist which has afterwards
to be wound on spools for sale, each of which spools has to contain a definite
length of silk twist.
This silk twist, for tailors' use, has to be wound on the spools in several threads
(varying in number according to the order of the buyer) running together, and
therefore on the large bobbin A several threads of silk twist running together are
wrapped in one continuous length before this bobbin is fixed on the spindle and
before the improvement which I wish to patent is used.
The line marked M is therefore a compound thread consisting of several threads
of silk twist running together.
B is an iron ar, hinged at one end to the stand C, and the other end resting on
the edge of the large bobbin A. acts as a break, prevents the bobbin turning by its
own impetus, thus unwinding its silk twist on to the floor or table and keeps the
silk twist wrapped sufficiently tightly round the wheel F to cause its revolution
to be in exact proportion to the length of silk twist which may pass round it.
The several threads of silk twist running together are drawn off from the large
bobbin A, causing its revolution, by being wound on to the spool D (upon which it
is desired to, wind a definite number of yards for sale) which is made to revolve by
being fixed tightly on a spindle turned by the hand-wheel and strap E.
The silk twist in its passago from the large bobbin A to the spool D is made to
pass round the wheel F, which it causes to revolve, and it is by means of this
wheel F and the apparatus with which it is connected by the shaft running
through its axis and supporting it in its revolution, that the silk wound on to the
spool D is measured.
The distance round the wheel F is exactly 36 inches, or in other words the
distance from the edge G of any one of the six light portions which project from
its axis, to the edge G of that next to it is exactly six inches. Each of these
projecting portions is very light, and made of sheet iron in two parts, one fixed to
the axis of the wheel F and the other novable, so that it may be lengthened by
drawing out the movable part which can be fixed at the desired length by means
of the small screws shown in the drawing. The reason why provision is made for
lengthening the projecting portions is that it is sometimes desired to increase the
distance round the wheel F to somewhat more than 36 inches.
The small holes in the movable part of each projecting portion through which
the screws pass securing the movable part to the fixed part, are an equal and
definite distance apart so that the extent to which each projecting portion is
lengthened and consequently the increase of distance round the wheel F is
accurately known.
Every complete revolution made by the wheel F causes the teeth-wheel I to
revolve the distance of the space occupied by one of its teeth, and thus when the
teeth wheel I has made one revolution the number of its teeth is the same as the
number of revolutions made by the wheel F, and therefore, the number of yards of

page_text: silk twist wound on the spool D. And before the machine is started, with the
spool D empty, the teeth-wheel I is placed so that the peg K which is fixed to it
has the end of the light iron bar L resting upon it, and when on working the
machine by turning the hand-wheel E the peg K again comes in contact with
the light iron bar L we are told that the teeth-wheel I has made exactly one
revolution.
Therefore by using teeth-wheels like I, having the requiste number of teeth, we
can measure accurately on to the spool D whatever number of yards of silk twist
we wish.
If it is wished to increase very slightly the length of silk twist wound on to
the spool D without changing the teeth-wheel I recourse is had to increasing the
length of the projecting portions of the wheel F to the required extent.
N, of course, is really a screw, the worm of which extends about three times
round it, and as it revolves it causes the revolution of the teeth-wheel I.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:
The wheel F, or any modification of it in size or shape or material, which is
caused to revolve by tailors' sewing silk twist, coming from any source, such as
the bobbin A, passing around it, for the purpose of measuring the length of this
silk twist wound on to the spool D.
