PROVISIONAL SPECIFICATION.
Improvements in the Joining or Piecing of Yarns, and in Apparatus
therefor.
I, JAMES WALES of the Firm of J. Wales & Son, Peveril Works, Peveril
Street, in the Borough of Nottingham, Silk Spinner, do hereby declare the nature
of this invention to be as follows:-
This invention relates to the joining, piecing or connecting of silk cotton or other
yarns without knots and without forming thick or lumpy places at the point of
connection and to apparatus for holding the yarn while the joint is made.
In carrying out this invention the apparatus for holding the ends of the yarn is
preferably formed by a foundation plate to which are secured four spring clips
preferably fixed in a vertical position in a straight line and at a suitable distance
from each other. These clips are adapted to securely hold the yarn or yarns which
are pressed between the two inner faces of the clips."
Between the two inner clips and preferably arranged centrally on each side of
the foundation plate are two double clips each adapted to hold two or more
threads.

When making a joint the two pieces of yarn are each secured in the two outer
clips with their ends slightly overlaying in the centre of the foundation plate, the
strands in each end are then divided and pulled open so as to force the twist back
towards the end clips where it is retained by pushing the yarn into the inner clips
the divided strands are then pushed into the central side clips.
When the ends of both pieces of yarn have been opened out in the manner
described the separated strands of each piece of yarn are independently connected
or pieced to a strand in the other part as follows:-
A strand is taken from each piece of yarn and the two are overlaid, the two ends
of the strands are then untwisted and the surplus length pulled out and both are
then twisted together.
When all the strands have been independently connected in this manner both
pieces of yarn are released from the two inner clips and the twist at once returns,
with a little assistance, to the separated strands and twists them together again
and the joint is complete. The yarn may then be removed from the outer clips.
With the foregoing arrangement two pieces of yarn may be joined or pieced
together and the joint can scarcely be detected and it is specially applicable to
yarns which are worked up in machines in which yarns containing knots cannot be
employed or are very objectionable.
In place of the spring clips other suitable arrangements may be employed for
holding the yarn during the operation.

Improvements in the Joining or Piecing of Yarns, and in Apparatus
therefor.
I, JAMES WALES of the Firm of J. Wales & Sons Peveril Works, Peveril
Street, in the Borough of Nottingham, Silk Spinners do hereby declare the nature
of this invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
This invention relates to the joining, piecing or connecting of silk, cotton or
other yarns, without knots and without forming thick or lumpy places at the point
of connection, and to apparatus for holding the yarn while the joint is made.
It will be best understood by reference to the accompanying drawings in which
Figure 1 is a side elevation.
Figure 2 a plan, and
Figure 3 an end view of the apparatus constructed according to my invention.
Like letters indicate like parts throughout the drawings.
In carrying out this invention the apparatus for holding the two ends of the yarn
is preferably formed by a foundation plate a to which are secured four spring
clips b b c c arranged as shown. The clips b b c c may each be formed by bending
a strip of metal as shown, one part being bent or doubled over the other so as to
form a clip into which the yarn is pressed and securely held.
Between the two inner clips c c and preferably on the sides of the foundation
plate are two clips ff each adapted to hold two or more threads or strands and
preferably constructed by bending a strip of metal in the manner shown and similar
to that hereinbefore described, with reference to the clips b c.
When making a joint the two pieces of yarn d are each secured in the two outer
clips 66 with their ends overlaying in the centre of the foundation plate a, the
strands e in the ends of the yarns d d are then each in turn divided and pulled open
so as to force the twist back against the outer clip b. When the strands are
divided up to the inner clip e the yarn is pushed into this clip and the twist from
the separated strands is retained between that point and the outer clip b. The
divided strands e may be then held by pushing them into the clips ff till required.
When the ends of both pieces of yarn have been opened out in the manner
described the separated strands e of one piece of yarn are independently connected
or pieced to the strands in the other piece in the following manner.
A strand e is taken from each piece of yarn and the two overlaid, the ends of
both strands are then untwisted, the surplus length pulled out and the two ends
then connected by twisting the loose fibres of one end with those of the other as
shown at g.
When all the strands e have been connected in this manner both pieces of yarn
are released from the inner clips c c and the twist returns with a little assistance to
the separated strands and twists them together again.
The joint is then complete and the yarn may then be removed from the outer
*clips b b.
With the foregoing arrangement two pieces of yarn may be expeditiously joined
or pieced together, and the joint can scarcely be detected and it is specially
applicable to yarns which are worked up in machines in which yarns containing
knots cannot be employed or are very objectionable.
In place of the spring clips other suitable arrangements may be employed for
holding the yarn during the operation of joining or piecing.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is ;-
1. In the joining piecing or connecting of yarns separating the strands retaining
the twist during the process of connecting the strands and returning it to the
separated strands again substantially as herein described.
2. In apparatus for use in the piecing or connecting of yarns the combination
with a plate a of clips such as b and c or their equivalent for holding the yarn and
retaining the twist substantially as described and illustrated in the accompanying
drawings.
3. In apparatus for use in the piecing joining or connecting of yarns the
combination with a plate a and clips such as bc of one or more clips such as f
substantially as described and illustrated in the accompanying drawings.
4. The combination and arrangement of parts constituting the complete apparatus
for use in the piecing joining or connecting of yarns substantially as herein
described and illustrated in the accompanying drawings.
Dated this 14th day of July 1894.
