1, WILLIAM TATHAM of Vulcan Works, Rochdale, in the County of Lancashire,
Machine Maker, do hereby declare the nature of this invention to be as
follows:-
My invention has reference to the flyers of slubbing & roving frames and similar
machines,--one of the two legs of such flyers is commonly made tubular but with
an opening or slit down its outermost side farthest from the spindle. This opening
or slit is for the convenience of passing the thread coming from the rollers into and
down the tube for attaching it to the bobbin or spool on which it is wound.
The two edges of the tube forming the slit between them are even and equally
distant from the centre of the tube or thereabouts, the tubular leg so constructed is
a source of much trouble & bad work, as by the revolutions of the flier and the
centrifugal force acting on the thread in the tubular leg, the thread is forced to the
opening or slit and oftentimes when the thread becomes a little slack it is forced
from the leg through the slit and at other times loose fibres and particles of seed &
leaf which are on the passing thread fasten & accumulate in the slit and obstruct
its passage, in both these cases a stoppage of the machine is necessary, in the
first case to restore the thread to the tube and in the other to remove the
obstruction.
My improvement consists in admitting a current of air into the tubular leg by
which the passing thread may be forced back from the slit so as to prevent it leaving
the leg or of depositing seeds and other foreign matter in the slit for which purpose
I form suitable slits or openings in the leg through which the air may be admitted.
By another modification I construct the slit in advance of the one in common use
that is I form it on the advancing or leading side of the leg and out of the way of
the thread's passage.

COMPLETE SPECIFICATION
Improvements in or applicable to Slubbing and Roving Frames and
similar Machines for Twisting and Winding Fibrous Materials.
I, WILLIAM TATHAM, of 200 Drake Street, and Vulcan Works, Rochdale, in the
County of Lancaster, Machine Maker 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 :-
My invention has reference to the flyers of slubbing, intermediate and roving
frames and similar machines. One at least of the two legs of such flyers is
commonly made tubular, but with an opening or slit down its outermost side which
is farthest from the spindle. This opening or slit is for the convenience of passing
the thread or sliver coming from the drawing rollers into and down the tube in
order to attach it to the bobbin or spool on which it is to be wound. The two edges
of the tube between which the slit is formed are even and equally distant from the
centre of the tube or thereabouts in the ordinary arrangement, and when so con-
structed is a source of much trouble and bad work, as by the revolutions of the
flyer, the centrifugal force acting upon the thread or sliver within the tubular leg
causes the sliver or thread to be thrown to the opening or slit and oftentimes when

page_text: the thread or sliver becomes a little slack it is forced from the tubular leg through
the slit and at other times loose fibres and particles of seed and leaf which are
carried along with the passing thread or sliver adhere and accumulate in the slit
and obstruct its passage, in both these cases a stoppage of the machine is necessary,
in the first case, to restore the thread to the tube of the flyer and in the other, to
remove the obstruction.
My invention consists in making the tubular leg of the flyer with the slit for
introducing the thread or sliver on the "leading" side so that the slit will face in
the direction in which the flyer rotates, and so that the air will thus be driven
directly into the slit in the tubular leg of the flyer, or my invention consists in making
the slit in the flyer in the ordinary position in the tubular leg, but with one edge
of the metal on one side of the slit, nearer to the centre of the tubular part of the
leg of the flyer then the other, so that the opening or slit thus formed will face the
air in the direction in which the flyer rotates.
By this arrangement of the slit, centrifugal action upon the sliver or thread
will not cause it to pass out of the slit in the tubular leg of the flyer when
slack and should it tend to pass out, the air which the slit faces when the
flyer is revolving will drive it back and the air thus passing into the slit will also
tend to keep it free from leaf, dirt or foreign matter tending to obstruct it.
Fig. 1 is a side elevation; Fig. 2 is an edge elevation, and Fig. 3 a plan section
at AB Fig. 1 of a presser flyer according to my invention.
The slit a, is made in the tubular leg, on that side of it towards which the
flyer rotates, and such slit thus faces the air when rotating, which is driven into
the slit.
The flyer is one such as is used when the bobbin "leads" or is rotated faster than
the flyer, but when the flyer or spindle "leads" or goes faster than the bobbin, the
presser is or may be placed on the opposite side of the tubular leg of the flyer the
slit being placed on that side of the tubular leg to face in the direction in which
the flyer rotates.
Fig. 4 is a section of the tubular leg of the flyer according to my invention when
the slit is formed in the ordinary position but with one edge bent in, nearer the centre
of the tubular leg so that the slit or opening between the two edges will face the
air in the direction in which the flyer rotates.
It will be seen in Fig. 4, that one lip b', forming one side of the slit a, is nearer
the centre of the tubular leg b, of the flyer than the other lip b², forming the other
side of the slit a.
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. The construction of flyers for slubbing, intermediate and roving and similar
frames with the slit for the sliver or thread to be passed into the tubular leg on
that side of it, which will face the air when the flyer rotates, substantially as
herein before described and illustrated by Figs. 1, 2 and 3.
2. The construction of flyers for slubbing, intermediate and roving and similar
frames with the slit in the tubular leg of the flyer for the sliver or thread to be
passed into the tubular leg, in the ordinary position, but with one lip nearer the
centre of the tubular leg so that the opening thus formed will face the air when the
flyer rotates, substantially as hereinbefore described and illustrated by Fig. 4 of
the drawings.
