This invention relates to certain parts of the frames in which flax or similar
fibres are spun by the wet process and is designed with the object of providing
saddle for the rollers. by which the weight or pressure on the top rollers can be
adjusted or distributed at will onto the drawing and retaining rollers without
altering the position or line of the weight wire.
It consists essentially of a double saddle or the combination with the saddle of
a second or supplementary saddle resting upon it the point of contact of the two
being adjustable so that the weight, may be varied or adjusted from one roller to
the other.
The invention may be carried out in several ways either by pivoting one saddle
and allowing the top slide from the other to pass through it or by pivoting or-
supporting both one above the other or by pivoting or supporting the top one
alone the top one being provided with a movable or adjustable knife edge which
bears upon the lower one the weight wire being in either case attached or
connected to the upper one.
In one form the ordinary saddle is supported by the U's on the arms of the
stands with a journal at or near the end to support the pressing drawing roller.
The top slide is carried by an outer bar or supplementary saddle and passes
through a slot or slit in the lower saddle to reach the journal of the top retaining
roller. Or the top slide may be forked or slotted for the lower saddle to pass
through it. The position of the top slide is adjustable. To the supplementary
saddle attached a movable or adjustable bearing piece preferably in the form
of a knife edge which bears upon the lower saddle. The lower saddle is also
preferably fitted with an adjustable bearing piece formed with a V groove or nick
to receive the knife edge. On the top surface the supplementary saddle is
provided with a nick or groove to receive the knife edge of the "humbug" which
holds. the weight wire in the ordinary, way. The position of the top slide and of
the bearing pieces can both be altered to adjust the distance between them and
the weight wire and thereby the weight or pressure on the two rollers can be
adjusted without altering the position or direction of pull of the weight wire.
In another form the lower saddle is like the ordinary saddle carrying a journal
at its end for the pressing drawing roller and the movable top slide for the
pressing retaining roller. The second or supplementary saddle is pivoted upon or
is supported by the drip pipe, the stand arms or other suitable supports. It is
provided with a movable or adjustable knife edge or other projecting piece which
bears upon the, top of the under saddle. The "humbug" of the weight wire
presses against the supplementary saddle and the weight or pressure on the under
saddle is adjusted by altering the position of the knife edge or bearing piece.

Improvements in the Saddles of Machines for Spinning Flax and
similar Fibres.
We, FRANK NAYLOR, of 96 Dover Street, Belfast, in the County of Antrim,
Ireland, Draughtsman, JOSHUA VALENTINE EVES, of Forth River Mili, Falls Road,
Belfast, aforesaid, Manager, and ARTHUR GREEVES, of Forth River Mill, Falls
Road, Belfast, aforesaid, 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 certain parts of the frames in which flax or similar
fibres are spun by the wet process and is designed with the object of providing a
saddle for the rollers by which the weight or pressure on the pressing rollers can be
adjusted or distributed at will on to the drawing and retaining rollers without
altering the position or line of the weight wire.
It consists essentially in the construction of a saddle having a second or supple-
mentary saddle in combination with and resting upon the ordinary or main saddle
the supplementary saddle being provided at the drawing end with an adjustable
connecting or bearing piece which rests upon the other saddle and at the retaining
roller end either carries the top slide for the pressing retaining roller or is pivoted to
a fixed support, the weight or force exerted on the rollers being varied or adjusted
by moving the adjustable connecting piece whilst the weight wire retains its original
position.
The invention may be carried out in several ways as will be fully described with
reference to the accompanying drawings.
Fig. 1. transverse sectional elevation of the beam stand and rollers showing one
form of the improved saddle applied thereto.
Fig. 2. front elevation of the supplementary saddle..
Fig. 3. end elevation of the two saddles.
Fig. 4. side elevation of ends of saddles showing connecting piece attached to one
fitting into nicks or grooves cut in the other.
Fig. 5. sectional elevation of beam stand and rollers showing a modified form of
the improved saddle.
The beam A the stand B the drawing roller C the pressing drawing roller D
the retaining roller E and the pressing retaining roller F are constructed in any
ordinary or convenient manner and the improved construction. of saddle may be
applied to any arrangement of these parts where it is desirable to do so.
Referring to Figs. 1 to 4. The saddle G which takes the place of the ordinary
saddle is supported by or pivoted upon the U brackets on the arms 6 of the
stand B. It is provided at one end with a pin or pivot y to engage with the
U brackets and at the other with a journal or bearing to engage with the axle of
and support the pressing roller D in position over the drawing roller C. It is also
formed with a slot g' through which the top slide H passes without coming into
contact with it, the top slide being carried by the supplementary saddle I. The
supplementary saddle I is placed above the other saddle G and to the drawing
roller end is a movable or adjustable connecting or bearing piece J preferably with
a knife edge at its lower end which bears or rests upon the lower saddle G. To
the other end of this supplementary saddle I is adjustably attached the top slide H
the position of which can be moved or adjusted to correspond with that of the
bottom slide and the retaining roller E. The top slide H passes down through a
slot g'in the saddle G or it may be slotted or forked for the saddle G to pass
through it. The adjustable connecting piece J is attached to the supplementary
saddle I by a small set screw or other suitable means and the saddle G is prefer-
ably fitted with an adjustable bearing piece K formed with a V groove or nick k
to receive the knife edge of the connecting piece J. Instead of the bearing

page_text: piece K grooves may be cut in the surface of the saddle G as shown in Fig. 4..
On the top surface the supplementary saddle I is provided with a nick or groove i
to receive the knife edge of the "humbug" L which holds the weight wire M in
the ordinary way. The position of the connecting or bearing pieces J and K are
moved or altered to adjust the distance between them and the weight wire M and
thereby the weight or pressure on the two pressing rollers D and F can be adjusted.
without altering the position or direction of pull of the weight wire M.
Referring to Fig. 5 the lower saddle G is shown in shape like the ordinary saddle.
carrying a journal at its end for the pressing drawing roller D and the movable top.
slide H for the pressing retaining:roller F. The second or supplementary saddle I
is pivoted upon or is supported by the drip pipe N or it may be supported by the
stand arms or other suitable supports.
Ꭻ
Between its pivoted end and the weight wire M which passes through it we attach
to the supplementary saddle I the movable or adjustable connecting or bearing.
piece J provided with a knife edge which rests upon the top of the other saddle G..
The "humbug" L of the weight wire M presses upon the supplementary saddle I
and the weight or pressure on the under saddle G is adjusted by altering the position
of the knife edge or bearing piece J.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. A saddle for the rollers of spinning frames constructed in two parts, one part.
pivoted at one end and supporting the pressing drawing roller in position and the
other part resting thereon provided with an adjustable connecting piece at one end
which bears upon the first part and at the other end carrying the top slide for the
pressing retaining roller which passes down through or past the first part the weight.
or pressure of the weight wire being adjusted by moving the connecting piece
substantially as described.
2. A saddle constructed with an ordinary or main saddle pivoted in U brackets in
combination with a supplementary saddle resting therein and provided with an
adjustable connecting piece placed at the end over the drawing roller whereby the
pressure or weight on the roller is adjusted without removing the weight wire
substantially as described and shown.
3. The arrangement and combination of parts forming a saddle for the rollers of
spinning frames substantially as described and shown with reference to Figs. 1 to 4
or Fig. 5 of the drawings.
