IMPROVEMENTS IN WET SPINNING FRAMES
Year: 1885

page_text: I, JOHN BARBOUR PIRRIE of Barn Mills Carrickfergus Ireland Mill Manager do
hereby declare the nature of my invention for IMPROVEMENTS IN WET SPINNING
FRAMES to be as follows:-.
These improvements consist of a novel arrangement of saddle for controlling the
position of the top and bottom pressing rollers whereby the required pressure can
be applied to each roller separately and the amount of pressure on each varied
without affecting the other.
This is accomplished by making the saddle in two parts working on a common
hinge or centre this hinge or guiding rod being between the upper and lower
pressing rollers.
This division of the saddles into two parts permits of their being used to control
not merely the parallelism of the pressing rollers to the drawing and retaining
rollers but also their position endways on the rollers for this purpose the bearings
are made larger in the centre and so form the required guide and also retain the
lubricant.
The bushes on the saddles are swivelled so that any slight deviation of the saddle
from being at right angles to the rollers is accommodated and the Butes in the
rollers cannot be crossed.
The pressure is applied to each portion of the saddle by rods which are connected.
to weighted levers placed behind the beam which supports the rollers and below
the ordinary troughs for water.
By the use of separate levers and weights for both the bottom and top pressing
rollers the amount of pressure applied to each can be regulated to any desired
degree so that no undue pressure is applied to the bottom or drawing rollers to
secure sufficient pressure on the top or retaining 'rollers which often occurs by the
ordinary arrangement of saddles in which the pressure is applied by one saddle
acting upon both bottom and top rollers.

page_text: JOHN BARBOUR PIRRIE of Barn Mills Carrickfergus Ireland Mill Manager do
hereby declare the nature of my invention for IMPROVEMENTS IN WET SPINNING
FRAMES 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 of a novel arrangement of saddle for controlling the
position of the top and bottom pressing rollers whereby the required pressure can
be applied to each roller separately and the amount of pressure on cach varied
without affecting the other.
The means whereby this is accomplished will be understood from the following
description reference being had to the drawing herewith in which the same letters
and figures of reference always apply to the same or like parts.
Fig. 1 being a section of so much of a wet spinning frame as is necessary to
shew the application of these improvements.
Figs. 2. 3 and 4 are detached views of parts referred to.
The saddle is made in two parts (a a¹) working on a hinge or centre (6) common
to both this hinge or guiding rod (b) being between the upper and lower pressing
rollers (c c¹).
This division of the saddles into two parts (a a¹) permits of their being used to
control not merely the parallelism of the pressing rollers (c c') to the drawing and
retaining rollers (d) but also their position endways on the rollers (d d¹) for
this purpose the bearings or necks are made larger in the centre as shewn in fig. 4
and so form the required guide endways and also retain the lubricant.
The bushes in the saddle (a) are swivelled the bush proper (a²) having a
projecting pin as shewn detached in fig. 2 which is inserted in the block (3) fig. 3
which is moveable in the saddle (a) to suit the reach so any slight deviation of the
the saddle (a) from being at right angles to the rollers (d d¹) is accommodated and
the flutes in the rollers (c d³) cannot be crossed.
The pressure is applied to each portion of the saddle (a al) by rods (e e¹) which
are connected to weighted levers (e² e³) placed behind the bean (f) which supports
the rollers (d') and below the ordinary troughs (g) for water.
By the use of separate levers and weights (e² e³) for both the bottom (c¹) and
top (c) pressing rollers the amount of pressure applied to each can be regulated to
any desired degree so that no undue pressure is applied to the bottom or drawing
rollers (c¹ d) to secure sufficient pressure on the top or retaining rollers (c d¹) which
often occurs by the ordinary arrangement of saddles in which the pressure is 3
applied by one saddle acting upon both bottom and top rollers.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
(1.) The making of saddles for wet spinning frames in two pieces hinged on
a common or fixed centre as described and
(2.) The making of pressing roller bushes swivelled in the manner described and
illustrated.
