PROVISIONAL SPECIFICATION.
Improvements in Spinning Machinery for Pirns or Cops of Flax or
similar Fibres.
THOMAS WATSON of No. 1 Springfield Villas, Springfield Road, Belfast
Co. Antrim, Engineer do hereby declare the nature of this invention to be as
follows:-
These improvements are calculated to make longer pirns or cops than any
heretofore produced without a corresponding lengthening of the spindle blade.
The spindles may thus be driven at the same speed for the longer pirn as for the
shorter, thereby increasing the turn off.
In effecting these improvements 1 employ two fliers, alternately, the longer one
being used to lay on the lower half of the length of the pirn or cop, after this part
has been laid on the flyer is removed & the shorter one substituted to finish the
upper half & complete the cop.
Or, I employ one flyer with legs of unequal length the lower half of the cop or
pirn being made by longer leg & the upper half by shorter leg, the thread or yarn
under process being removed from the former to the latter for this purpose.
In lieu of either of the above methods, I use a flyer having legs of equal length,
having two eyes, one for the first half of pirn or cop at the end of the leg, as
usual, the other at the proper position in the length of second leg to commence &
complete the second or upper half of the pirn or cop as above described.

THOMAS WATSON of No. 1 Springfield Villas, Springfield Road, Belfast,
Co. Antrim, Engineer 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:-
These improvements are calculated to make longer pirus or cops than any
heretofore produced without a corresponding lengthening of the spindle blade.
The spindles may thus be driven at the same speed for the production of long
piros as for short ones with a corresponding increase in the turn off or production
of yarn.
In carrying out these improvements I employ two flyers, alternately, the longer
one being used to lay on the lower half of the length of the pirn or cop; after
this part has been laid on this flyer is removed and the shorter one substituted to
finish the upper portion and complete the cop or pirn.
Or I employ one flyer with legs of unequal length, the lower half of the cop or

page_text: pirn being made by the longer leg and the upper half by the shorter leg: the
thread or yarn under process being removed from the former to the latter for this
purpose.
In lieu of either of the above methods 1 use a flyer having legs of equal length,
furnished with two eyes, one, for the production of the first or lower half of the
cop or pirn being situated at the end of the leg, as usual, the other eye in the
proper position or at the proper point in the length of the second leg for
commencing and completing the second or upper half of the cop or pirn, the
thread or yarn being changed, for this purpose from one eye and leg to the other
as in the case of the flyer having legs of unequal length.
The annexed drawing illustrates the three methods of carrying out my invention:
referring thereto :-
Figures 1 and 2 are front elevations of a pair of flyers, a long one and a short
one, which I use alternately. Fig. 1, the longer one, is employed to produce the
first or lower half of the cop or pirn, the shorter one, Fig. 2, being then substituted
for it to complete the pirn.
Figure 3 is a front elevation of a flyer the legs of which are unequal in length.
The eye, A, of this flyer lays on the first or lower half of the pirn or cop after
which the yarn or thread is removed from eye, A, to eye B, for the completion of
the pirn.
Figure 4 is a front elevation of a flyer having legs of equal length and furnished
with two eyes, one of these eyes, C, is placed at the end of the leg upon which it
is mounted, the other eye D, being placed at a suitable point in the length of the
second leg for effecting the completion of the cop or pirn after the lower half of
same has been laid on by the first eye, C; the yarn or thread being changed from
eye C, to eye D for this purpose.
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 :-
I. The use in pirn or cop spinning machines of pairs of flyers, each pair con-
sisting of a long and a short flyer, the long flyer being used to commence and the
short flyer to complete the formation or production of the pirn or cop as herein-
before described.
II. The use in pirn or cop spinning machines of flyers with legs of unequal
length for the purpose of making cops or pirns by changing the yarn or thread
from one leg to the other as hereinbefore described.
III. The use in pirn or cop spinning machines of flyers, with legs of equal
length, furnished with an eye at the end of one of their legs, as usual, but having,
in addition, an eye on the other leg so far removed from the end of same as I find
convenient for the purpose of effecting the completion of the cop or pirn which
has been partially produced by that leg of the same flyer having the eye at
its end.
IV. The novel construction of flyer, for pirn or cop spinning machines, with legs
of unequal length as described.
V. The construction of flyer, for pirn or cop spinning machines, with one eye
fastened at the end of one leg and an eye fastened upon the other leg at a point
more or less removed from the end of same.
