PROVISIONAL SPECIFICATION.
Improvements in Spinning Frames for Flax, Hemp, Tow, Jute, and
other Fibres.
I, JOHN PERRY of Lannoy, Nord, France, Spinuing Mills Manager, do hereby
declare the nature of this invention to be as follows:-
This invention has reference to spinning frames for flax, hemp, tow, jute, China
grass and other fibres and specially to the stand and saddle or carrier at the under-
side of which are placed the bearings of the pressing rollers that work in conjunction
with the drawing rollers.
The characteristic feature of the invention is a novel form or construction of the
stand and saddle above referred to. The back end of the saddle is flat at the sides
and has a vertical notch or opening in the lower edge. This flat part fits with
slight friction and little play in a fork or opening of the supporting head or
bracket and a transverse pin is passed through the fork and through the notch in
the back end of saddle or carrier and retains the saddle in its position. This pin
allows the saddle to move up and down according to the variable diameter of the
pressing rollers; large and small pressing rollers can be employed as required.
The saddle accommodates itself to all requirements. Owing to the guidance of the
pin and the freedom of the saddle to move to different heights according to the
diameter of the pressing rollers, the pressure on the drawing rollers is always
normal and perfect. The back end of the saddle and its guide being flat there is no
wear at this part and however much the bearings of the pressing rollers may
become worn the pressure always remains normal. The saddle carries a removable
bearing for the first pressing roller so that it can be replaced by another whea
worn. The bearing of the second pressing roller is retained by a screw and its
distance from the first bearing is adjustable as usual in accordance with the
distance between the first and second drawing rollers.
The above stand and saddle supply a want which has been long felt particularly
in flax and tow spinning. They afford facility to reduce the reach between the
rollers allowing them to almost touch; a more regular thread and one possessing
greater strength is thus produced.

COMPLETE SPECIFICATION.
Improvements in Spinning Frames for Flax, Hemp, Tow, Jute, and
other Fibres.
I, JOHN PERRY of Lannoy, Nord, France, Spinning Mills 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 has reference to spinning frames for flax, hemp, tow, jute, China
grass and other fibres and specially to the stand and saddle or carrier at the under-
side of which are placed the bearings of the pressing rollers that work in conjunction
with the drawing rollers..
The characteristic feature of the invention is a novel form or construction of the
stand and saddle above referred to. The back end of the saddle is flat at the sides

slight friction and little play in a fork or opening of the supporting head or bracket
and a transverse pin is passed through the fork and through the notch in the back
end of saddle or carrier and retains the saddle in its position. This pin allows the
saddle to move up and down according to the variable diameter of the pressing
rollers; large and small pressing rollers can be employed as required. The saddle
accommodates itself to all requirements. Owing to the guidance of the pin and the
freedom of the saddle to move to different heights according to the diameter of
the pressing rollers, the pressure on the drawing rollers is always normal
and perfect.
The back end of the saddle and its guide being flat there is no wear at this part
and however much the bearings of the pressing rollers may become worn the
pressure always remains normal. The saddle carries a removable bearing for
the first pressing roller so that it can be replaced by another when worn.
The
bearing of the second pressing roller is retained by a screw and its distance from the
first bearing is adjustable as usual in accordance with the distance between the first
and second drawing rollers.
The above staud and saddle supply a want which has been long felt particularly
in flax and tow spinning. They afford facility for reducing the reach between the
rollers allowing them to almost touch, a more regular thread and one possessing
greater strength is thus produced.
The accompanying drawings represent a stand and saddle constructed in
accordance with my invention, Figure 1 being a vertical section, Figure 2 a front
view and Figure 3 a plan; Figure 4 is a side view of the saddle only.
A is the support or carrier of the apparatus, B the supporting head or bracket for
the saddle, C the saddle, E the weighted rod, F the first drawing roller, G the first
pressing roller, H the second drawing roller and K the second pressing roller.
The back end S of the saddle C is flat at the sides and has a vertical notch or
opening Z in the lower edge. The flat part S fits with slight friction and little
play in a fork or opening R in the supporting head B, and a transverse pin P is
passed through the fork R and through the notch % of the saddle and retains the
saddle in position, while allowing it to move up and down according to the variable
diameter of the pressing rollers. The saddle carries a removable bearing D for the
pressing roller G. The bearing L of the pressing roller K is retained by a screw M
and its distance from the bearing of the roller G is adjustable in the slot T of the
saddle as usual in accordance with the distance between the rollers F and H.
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 1
claim in respect of spinning frames is :-
1. The particular construction or form of the back end of the saddle and of the
corresponding part of the supporting head or bracket, substantially as and for the
purpose herein before described.
2. The combination or arrangement of parts comprising the specially constructed
saddle C, and supporting head B, the drawing rollers F, H, and the pressing
rollers G, K, substantially as herein before described and shown in the accompanying
drawings.
