PROVISIONAL SPECIFICATION.
Improvements in Machinery for the Preparation of Flax, Hemp,
Jute, and other like Fibres.
JAMES BARBOUR of Falls Foundry, Belfast, County Antrim, Ireland, Machine
Maker, do hereby declare the nature of this invention to be as follows:-
These improvements relate to preparing machines used for the drawing of flax,
hemp, jute and other like fibres, and comprises improvements connected with what
is technically known as the spring wires and gibs, which are used in conjunction
with the usual levers and weights for giving the required pressure to the drawing
rollers.
The improvements comprise the application and employment of adjustable guides
applied to the spring wires, said guides and the junction of the spring wires with
the weighting levers prevents any lateral movement of the gibs or presser roller
bearings. A length of the upper end of the guide wire is serrated or toothed
and corresponding teeth and indentations are made in the eye or hole in the gibs
for reception of the guide wire, so that the pull on the latter causes the serrations
of the gib and the guide wire to engage and automatically lock the gib and wire
together, this construction of connection affords great facilities for ready adjustment
of the guide wires to the gib.
The outer ends of the gibs being fitted or set to the inner face of the collars on
the roller axle so that the presser rollers are held in required working position
without the aid of the U's or U horn bars and axle nuts heretofore necessary and
which U's or U horn and axle nuts are dispensed with and there is less liability of.
the formation of laps thus making a more perfect drawing action and in addition
to this makes the machine more efficient and greatly simplifies the construction.

1,JAMES BARBOUR of Falls Foundry, Belfast, County Antrim Ireland, Machine
Maker, do hereby declare the nature of this invention and in what mauner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
These improvements relate to preparing machines used for the drawing of flax,
hemp, jute, and other like fibres, and comprise improvements connected with what
are technically known as the spring wires, and gibs, which are used in conjunction
with the usual levers and weights for giving the required pressure to the drawing
rollers.
The improvements comprise the application and eniployment of adjustable guides
applied to the spring wires, said guides and the junction of the spring wires with
the weighting levers prevents any lateral movement of the gibs or presser roller

page_text: bearings a length of the upper end of the guide wire is serrated or toothed and
corresponding teeth and indentations are made in the eye or hole in the gibs for
reception of the guide wire, so that the pull on the latter causes the serrations of
the gib and the guide wire to engage and automatically lock the gib and wire
together. This construction of connection affords great facilities for ready adjust-
ment of the guide wires to the gib.
The outer ends of the gibs being fitted or set to the inner face of the collars
on the roller axle so that the presser rollers are held in the required working
position without the aid of the U's or U horn bars, and axle nuts heretofore
necessary and which U's or U horn bars and axle nuts are dispensed with.
By this combination the machine is less liable to form laps, a more perfect
drawing action is obtained and the construction is greatly simplified.
Such being the nature and object of my said invention the following is a
complete description of same, reference being had to the accompanying drawings
in which:-
Fig. 1 is a front elevation of my improvements applied to the pressing rollers.
Fig. 2 is an end view partly in section of part of the framing with my improve-
ments applied thereto.
Fig. 3 is an end elevation of the guide drawn to an enlarged scale.
Fig. 4 is a plan view of Fig. 3.
Figs. 5, 6 and 7 are details drawn detached.
At is the spring wire extending from the weighting lever 2 to the gib 3
through an eye in which is passed the upper end of the spring wire as shewn.
The side of the eye of the gib is serrated and the corresponding side of the
upper part of the spring wire 1 is also serrated.
The fixed guides 4, 4 are connected to the sliver plate or the framing of the
machine, said guides receive the spring wires 1 and prevent any movement of the
upper part of the spring wires other than the direction given to them by the weighted
levers.
The lower ends of the spring wires 1 are connected to the weighted lever 2 by
the junction or cross rod 5, or direct to the lever 2 when latter occupies position as
shewn in detail Fig. 7.
The rod 5 serves to space and guide the lower ends of the spring wires 1 so
that the latter are absolutely controlled by the guides and rod 5 against side
movement.
The serrated portion of the eye of the gib 3 and the serrated part of the spring
wire 1 serve to hold and lock the gib 3 to the spring wire I so long as weight is
applied to the weighted lever 2, and when the weighting is removed from said
lever 2 the gil 3 admits of immediate adjustment by raising and lowering on the
spring wire as may from time to time become necessary by reason of the changed
diameter of the pressing rollers or for removal of the pressing rollers.
It will be seen that the inner face of the collars of the pressing rollers fit to the
outer ends of the gibs 3 and as the spring wires 1 are stayed and controlled by
the parts 4, 5 as described, the pressing rollers, are governed and controlled so
as to prevent any sideways or lateral movement thereof, and that the U's or U horn
bars and axle nuts heretofore employed are no longer necessary and the construction
is simpler and the number of parts less and greater facility of access is obtained
to the working parts of the machine.
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 is:-
1. In machines for purposes aforesaid spring wires having a serrated side and
gibs serrated, said spring wires being controlled as to movement other than the
direction given to them by means of parts such as 4 and 5 all in combination and
as described herein and illustrated by drawings annexed.

page_text: 2. In machines for purpose aforesaid, the employment of gibs controlled by
spring wires the collars and necks of pressing rollers fitting to the gibs as described
and illustrated by annexed drawings.
