PROVISIONAL SPECIFICATION.
Improvements in Thread Guides and Fibre Laying Appliances for
Twisting Machines.
We, THOMAS BIGGART AND COMPANY LIMITED, of Bridgend Mills, Dalry, in
the County of Ayr, North Britain, Worsted Spinners, and JOHN WILLIAM HODGSON,
of Bridgend Mills, Dalry, aforesaid, Spinning Master, do hereby declare the
nature of this invention to be as follows, that is to say:-
This invention comprises improvements specially designed for dealing with
yarns which have fibres projecting outwards from them, and the object is by
means of improved guides and connected parts to lay the loose fibres along the
yarn and to prevent those of one yarn from becoming entangled with the other
yarn.
In a machine to which the improvements are applicable the yarns, of which
there may be two to be twisted together, pass entirely round a vertical roller,
which may be of the kind known as a "trap" roller, and thence to the flyer or
equivalent. A guide piece for each pair of yarns is fixed to a rail, and has formed
through it a guide slit for each yarn one being sufficiently above the other to
guide the yarns onto the roller at such a distance apart as to prevent entangling.
At the front and back of the guide piece layers of felt, or flannel, or the like are
applied and are slitted like the guide but so that the yarns pass in contact with
the felt, or flannel so as to have their projecting fibres laid back. And there is
attached to the guide piece or other part an arm provided with a cushion of felt,
or flannel, or the like and adapted to bear against the roller. This cushion has
a further action in laying back the projecting fibres as the yarns pass between it
and the roller.
The improved apparatus may be modified to suit horizontal rollers, and to
operate on more than two yarns to be twisted together.

nature of this invention and in what manner the same is to be performed, to be

page_text: particularly described and ascertained in and by the following statement, that is
to say:-
This invention comprises impiovements specially designed for dealing with
yarns or threads which have fibres projecting outwards from them, and the object
is by means of improved guides and connected parts to lay the loose fibres along
the yarn and to prevent those of one yarn from becoming entangled with the
other yarn.
And in order that the said invention and the manner of performing the same
may be properly understood, we hereunto append a sheet of explanatory drawings
to be hereinafter referred to in describing by way of example, one modification
of the improvements.
Figure, 1, of the drawings is a plan, and Figure, 2, is a side elevation, partly
in section, of the improved apparatus. Figure, 3, is a front elevation, and
Figure, 4, a side elevation partly in section on an enlarged scale, of a main
portion of the improved parts. In these drawings the same reference letters are
used to mark the same or like parts wherever they are repeated.
In a machine to which the improvements are applicable the yarns, A, B, to
be twisted together are made to pass entirely round a vertical roller, C, as shown, of
the kind known as a trap" roller, and thence through guides, D), to the flyer, E,
or equivalent. Between the vertical roller, C, driven by band gearing, R, and
the bobbins, F, a guide piece, G, for the yarns, A, B, is provided which is fixed
to a rail, H, and has formed through it guide slits, J, K, for each yarn, A, and B,
one, J, being sufficiently above the other, K, to guide the yarns onto the roller, C,
at such a distance apart as to prevent entangling. At the front and back of the
guide piece G, layers, L, M, of felt, or flannel, or the like, are fixed, and are
slitted like the guide, but the slits, S, T, formed in them are made somewhat
smaller than the guide slits, J, K, so that the yarns, A, B, in travelling through
the guide piece, pass in contact with the felt or like material and thereby have
their projecting fibres laid back. An arm, N, adjustably fixed to the guide
piece, G, or other part, is provided with a cushion, P, of felt, or flannel or the
like, which is shaped, and fixed in position by adjusting screw, Q, so that it bears
against the vertical roller, C. This cushion, l', has a further action in laying
back the projecting fibres as the yarns, A, B, pass between it and the roller, C.
The improved apparatus may be modified to suit horizontal or other rollers,
and to operate on more than two yarns to be twisted together.
Having now particularly described and ascertained the nature of the said
invention and in what mauner the same is to be performed, we declare that what
we claim is;
-
Improvements in thread guides and fibre laying appliances for twisting
machines, comprising, in combination, a roller round which the yarns are made
to pass, a guide piece formed with a slit for each yarn, layers of felt or like
material fixed to the guide piece, and a cushion of felt or like material arranged
to bear against the roller and yarn substantially as and for the purposes herein-
before described with reference to the accompanying drawings.
