Improvements in Apparatus for Use in the Wet Spinning of Flax.
I, JOSHUA VALENTINE EVES, of Forth River Mill, Falls Road, Belfast, in the
County of Antrim, Ireland, Mill Manager, do hereby declare the nature of this
invention to be as follows :-
This invention relates to the pirns or shells or shell carriers used in the process of
spinning and it is designed to provide appliances better adapted for the purpose
than those at present in use.
I construct the pirn or shell carrier or bush which rests upon the spindle of sheet
metal (or other suitable material) and provide it with a base to receive the drag
band or cord. This base I make hollow and sufficiently large in diameter to stand
out from the body of the carrier to allow the paper pirn or shell which fits on it to
pass down below the level of the drag band. I an thus enabled to wind the yarn
close down to the drag band and retain a margin of paper unwound upon when the
pirn or shell is removed from the spindle.
I make a pirn or tube of paper and metal combined to give sufficient stiffness or
rigidity without increasing the size or bulk and to render it to a greater or less
extent impervious to moisture. I either take a very thin metallic sheet backed
with paper and roll it up into the form of a pirn or tube or the thin metallic sheet in
strips or otherwise is rolled up into the tube of paper being caused to adhere by
paste or adhesive substance or cement. The metallic sheet or strips are preferably
so rolled into the tube as to present a metallic surface in contact with the spindle
at the top and bottom and the metallic surface may be carried round the base on
the outside if desirable.
These pirns or tubes may be placed on the spindle with or without a carrier
or may be used with my "loose bush" described in the Specification of Patent
No. 15,047 of 1889.
Instead of strips of thin metallic sheets being inserted in the paper tubes a bush
may be applied at either or both ends or a piece of thin wire may be rolled up with
the paper during the formation of the tube.

Improvements in Apparatus for Use in the Wet Spinning of Flax.
I, JOSHUA VALENTINE EVES of The Forth River Mill, Falls Road, Belfast,
in the County of Antrim, Ireland, Mill Manager, 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 tube or shell and also to the pirn or shell carrier

page_text: It consists essentially in constructing the pirn bobbin or shell carrier which rests
upon the spindle with the base to receive the drag band or cord so formed that the
lower edge of the cop tube or shell shall get below the plane of the drag band or
cord and in constructing the cop tube or shell of paper and metal combined to
increase its stiffness or rigidity and render it more impervious to moisture without
increasing it in size or bulk.
The invention will be fully described with reference to the accompanying
drawings.

Fig. 9. Another modification.
The pirn bobbin or shell carrier A may be made of sheet metal wood or a com-
bination of these or other suitable material. I find sheet brass aluminium or other
non-corrosive metal very suitable for the purpose.
I construct the pirn bobbin or shell carrier A with the base a to receive the
drag band or cord C standing out at the bottom from the body of the carrier A
with a hollow or recess a¹ to allow the end of the cop tube or shell B which fits
over it to pass down below the level or plane of the drag hand C. I am thus
enabled to wind the yarn close down to the drag band and retain a margin of the
tube unwound upon when it is removed with the yarn upon it.
I make the cop tube or shell B of a very thin metallic sheet & backed with
paper rolled up into a tube as in Fig. 7 or I roll up thin metallic strips 6" along
with a sheet of paper b as in Figs. 8 and 9 the edge of the paper being caused to
adhere around the metallic strips 611 by means of paste or other adhesive substance
or cement. The metallic sheet & or strips are preferably so rolled into the
tube as to present a metallic surface in contact with the spindle at the top and
bottom and the metallic surface 6111 may be carried round the base on the outside
if desirable.
Instead of strips of thin metallic sheets being rolled up in the paper tubes a
bush of metal may be applied at either or both ends of the paper tube or a piece of
thin wire may be rolled up with the paper during the formation of the tube.
These cop tubes or shells B may be used with the pirn bobbin or shell carrier A
or with any other form of pirn or they may be used as a pirn without a carrier and
be placed direct upon the bare spindle or they may be used with my
"loose bush"
described in the Specification of my former Patent No. 15,047 of 1889.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In apparatus for the wet spinning of flax a pirn, bobbin or shell carrier
constructed with a base a standing out from the body of the pirn with a recess a
to receive the lower end of the cop tube B and allow it to extend below the level
or plane of the drag band C substantially as and for the purpose described.

page_text: 2. For use in the wet spinning of flax a cop tube or shell constructed of paper
and metal combined to increase its stiffness or rigidity and render it more
impervious to moisture substantially as described.
