Improvements in or connected with Certain Parts of Machines for
Spinning Flax and similar Fibres.
I JOSHUA VALENTINE EVES, of the Forth River Mills, 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 :-
The object of this invention is to provide a simple method of preventing the
loose ends of yarn left after doffing from lapping round the drag race of the bobbin
or pirn and from getting below the bobbin and lapping round the spindle blade.
In consists in surrounding the base of the bobbin or pirn with a ring or sheath
the upper edge of which being above the line of the drag band the loose end will
be guided on to that part of the bobbin or pirn intended to receive the yarn when
it is carried round by the flyer instead of as at present lapping in the drag race or
running in below the base of the bobbin and lapping round the spindle.
It will be fully described in reference to the accompanying drawings in which
Fig. 1. Section of part of traverse rail of spinning frame with the improve-
ments applied thereto.
Fig 2. Perspective view of washer.
Fig. 3. Same in modified form.
Fig. 4. Another modification.
Fig. 5. Sectional elevation of traverse rail showing another form of the
) invention.
The traverse rail A the bobbin or pirn B and the spindle C are constructed in
the usual way.
The base of the bobbin or pirn B I surround with a washer or sheath D. This
washer or sheath D is formed from sheet metal with a bottom plate d upon which
the pirn rests and with one two or more arms d' stamped out with and projecting
upwards from the bottom plate d. The arms d' serve to carry the ring at the
desired height (see Fig. 2).
Or I may use a cylinder d¹ Figs. 3 and 4 of drawn spun or cast metal with or
without a bottom plate d for the pirn to rest upon. One side of the cylinder is cut
away to allow the drag band to come into contact with the base of the bobbin.
It is obvious that instead of a washer or sheath D for each spindle a sheath may
be formed by means of a plate or plates extending the length of the traverse rail
with holes formed therein for the base of the pirns to pass through. Such an
arrangement is shown in Fig. 5 wherein the plate or rail E is supported over the
traverse rail A by studs e and constructed with the holes F forming rings
surrounding the base of the pirns B.
The washer or sheath which surrounds the base of the pirn rests upon or is
attached. to the traverse rail A or is so arranged as to rise and fall in unison
with it.
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 flyer frames for spinning flax or other fibres a sheath or ring surrounding
the base of the pirn and traversing in unison with the builder or traverse rail upon
which the pirn rests to guide the free or loose end of the yarn hanging from the
flyer eye after doffing onto the bobbin or pirn substantially as described.
2. In a machine for spinning flax or other fibres the combination with a bottom
plate or washer of a ton ring surrounding the base of the pirn supported by an

page_text: upright arm or cylinder with an opening in the side to admit the drag band sub-
stantially as and for the purposes described.
