PROVISIONAL SPECIFICATION.
Improvements in Spinning Frames for Flax and other Fibres.
We WILLIAM SCOTT of 76 Agnes Street, Belfast, Co. of Antrim, Ireland, Engineer,
and JAMES MACKIE 4 Albert Street Belfast Co. Antrim Ireland Machine Maker, do
hereby declare the nature of this invention to be as follows :-
This improvement consists in the use in wet spinning frames for flax and other
fibres, of a novel form and arrangement of "saddles" and "stands."
The saddles are made without arms having instead thereof controlling slots of
suitable curve in the top end.
The stands are side-bearing and control the saddle as to height by means of suitable
pins, fixed in correct position, on which the curved slots of sadille move when adjusting
its position to suit varying diameters of pressing rollers.
The curves of saddle are preferably recessed into each side, so as not to pass fully
through, but to leave a central diaphragm of metal sufficient to give strength to that
part of the saddle.
If desired they may pass through in which case a solid portion is left at the end of
the slot. The pins in stand do not meet at the points, sufficient space being left
to allow the central strengthening portion of saddle to pass freely through. The
stands may be fixed on the beam of frame, or on a bar running along the frame above
the rollers. The pins may be fixed directly in the stands, or in sliding brackets at
each side of them, to allow of adjustment of height at will.
If the stands be fixed on a bar they can be made to slide along it for adjusting
rollers endwise. The bar can also be fixed on movable brackets to be set in any
required position.

COMPLETE SPECIFICATION.
Improvements in Spinning Frames for Flax and other Fibres.
We WILLIAM SCOTT of 76 Agnes Street Belfast County of Antrim Ireland, Engineer
and JAMES MACKIE of Albert Foundry Albert Street Belfast County of Antrim Ireland
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 :-
These improvements consist in the use in wet spinning frames, of a novel form and
arrangement of "saddles" and "stands" in which the regulating U or curve is in
the "saddle" and arranged so that it can be cut accurately by machinery and so
secure perfect action of the pressing roller.
The accuracy of cutting permits perfect fitting of the guiding pins of the stand in
grooves of "saddle" giving longer wear and preventing jerking motion of the saddle.
The saddles are made without arms having instead thereof controlling slots of
suitable curve in the side or sides at the top end. These curved slots are preferably
recessed into both sides so as not to meet each other but to leave a portion of metal
in the middle to strengthen that portion of the "saddle" but they may be recessed
into one side only the solid portion being then at one side instead of in the middle.
The curved slots are open at the inside of saddle" for the passage of the pin or pins
of stand but are closed at outside. The saddle otherwise is of the ordinary type the
improvement being contained in the curved slots. The arrangement of the "stand" is

page_text: such as to give freedom to the legitimate movement of the "saddle" to prevent any
twisting and to ensure the maintenance of its correct position relative to the drawing
rollers.
The "stands" have pins in the top end arranged in pairs or singly to suit either
form of "saddle" in both cases space is left to allow the solid portion of "saddle" to
pass through. The stands are otherwise made and secured in the ordinary way, the
improvement in "stands" being contained in the pins.
The arrangements are clearly shewn in the drawings in which the same letters
always refer to the same parts-
Fig. 1 shews a side view of the "saddle" and "stand" as at work in the frame.
The back rollers A1 and A2 the pressing rollers B1 and B2 the saddle C the
stand D the curved slot in saddle E and the pins in stand F.
Fig. 2 shews a front view of same.
Fig. 3 shows a side view of top end of saddle and curved U and cross section of
same with curved slots in both sides and
Fig. 4 shews side and front view of top end of stand and arrangement of pins
suitable for same.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1st. The use of "saddles" having guiding U's or curves in the sides at the top
end as described.
2nd. The use of “stands" having a pin or pins for controlling saddles in the
manner and for the purpose described.
