CHARLES MURLAND and CLOTWORTHY WARREN MURLAND, of the firm of
James Murland, Manufacturers, and JOHN MONTGOMERY Mill Manager, all of
Annsborough, Castle Wellan, County Down, Ireland, IMPROVEMENTS IN OR
CONNECTED WITH MACHINES FOR PREPARING FLAX, HEMP, JUTE, AND SIMILAR
FIBROUS MATERIALS."
This Invention relates to improvements in or connected with machines for
preparing flax, hemp, jute, and similar fibrous materials for spinning, such as
spread boards, drawing frames, and roving frames, in which traversing fallers fitted
with gill pins, spikes, or heckle pins are used in drawing out the fibre, and has for
its object to effect automatic stripping or cleaning of the gill pins or heckles of
such machines from dust and pouse or loose fibres.
The improvements comprise a new arrangement and combination in such
preparing machines of the brush or brushes, by means of which the gill pins of the
fallers are cleared or cleaned, with novel lock spring holders or devices for
maintaining in position both the brush and the rubber or felt covered rubber board
which bears against and clears the usual under drawing roller of the machine.
The stripping or cleaning brush consists as usual of a series or row of bristles
which are fixed either directly in the bar of the ordinary rubber, which bears on
the lower drawing roller of the drawing frame, or other preparing machine, or in a
wooden strip fitted to such bar.

page_text: The brushes or bristles are also set in the usual way at an angle inclining
upwards and inwards, so that they press against and partly pass through the gill
pins of each faller as it descends in its guides at the front end of the machine, and
thus free the fullers of any loose fibre, pouse, or dust which may adhere to them;
and this loose fibre is freed from the brush by the lower edge of the succeeding
fuller as it drops, the lower edge of the fallers being rounded to prevent wear of
the brush..
The stripping or cleaning brush may be formed of a continuous strip of
projecting bristles, and it may be fitted to the framing of the machine instead of
to the rubber bar.
The felt covered surface of the rubber or rubber board, which bears longitudinally
against the horizontal under drawing roller, and the stripping brush or bristles
fixed to the rubber, are held up to their work or maintained in position by the
new or improved arrangement of lock springs or holders fitted to the machine
framing, and bearing on the under side of the rubber bar, one at each end. These
lock springs each consist of a short vertical bracket or guide against the front
edge or side of which is fitted a sliding bolt or bar which is held up by a spiral
spring surrounding its lower end, and bearing or pressing between a shoulder on it,
and a projecting guiding eye in the holding bracket. A slot is formed in the fixed
bracket near its upper end, through which a bolt or pin is passed and screwed into
the sliding bar, so that the bolt head retains it in position while allowing it to
move vertically. A swivelling weighted catch is jointed to the inner upper end of
the fixed bracket, and this catch retains or locks the spring bolt or bar when
pulled down by passing into the slot and bearing on the projecting pin or bolt
head.
.
For convenience of removing or adjusting the pin or bolt, the catch is made with
a knob to serve as a weight, and also to catch on to the upper end of the spring
bolt and hold it down. The upper end of the spring bolt is made flat to bear on
the under surface of the rubber, and is forined with a projecting pin to enter a hole
in the rubber. A projecting horn is formed on the spring bolt, by which this bolt
is drawn by hand to be retained and locked by the weighted catch when it is
desired to remove the rubber and brush. When the rubber and brush are again
fitted to the machine, the locking catch is released by hand, and the spring allowed
to act to raise the rubber and cause it to bear on the roller, and also bring the
brush into the cleaning position.

CONNECTED WITH MACHINES FOR PREPARING FLAN, HEMP, JUTE, AND SIMILAR
FIBROUS MATERIALS"
Our said Invention relates to improvements in or connected with machines for
preparing flax, hemp, jute, and similar fibrous materials for spinning, such
as

page_text: spread boards, drawing frames, and roving frames, in which traversing fallers fitted
with gill pins, spikes, or heckle pins are used in drawing out the fibre, and the
Invention has for its object to effect automatic stripping or cleaning of the gill
pins or heckles of such machines from dust and "pouse" or loose fibres.'

Our Invention is illustrated by the accompanying Drawings, in which figure 1 is
a transverse vertical section of part of a drawing frame or machine for preparing
flax, or similar fibrous material, to which our improvements are shown applied.
Figure 2 is a plan, and figure 3 is a front elevation of the same with details
removed. Figures 4, 5, 6 and 7 are elevations to a large scale of our improved
locking spring holders shown applied in combination with the rubber and cleaning
brush, and separately. The preparing machine illustrated is of the ordinary type
in which two or more pairs of rotating screws A, A', carried by a framing B, and
driven by suitable gearing from a counter shaft C, are caused to traverse a series
of fallers D fitted with gill pins or spikes d through which the flax or other
fibrous material under treatment is drawn by drawing rollers E, E¹, fitted in front
of the machine. The fallers are traversed forward as usual by the upper screws A
in, an upper horizontal row, are depressed or drop immediately behind the drawing
rollers E, E, and are traversed by the lower screws A' back as a lower horizontal
row to the rear of the machine where they are raised again to be acted on by the
upper screw shafts A.
The improvements comprise a new arrangement and combination in such
preparing machines of the brush or brushes F (by means, of which the gill pins d
of the fallers D are cleared or cleaned as they drop behind the drawing rollers).
with novel lock springs holders G or devices for maintaining in position both the
brush F and the rubber, or felt covered rubber board, H, which bears against and
clears the usual under drawing roller E of the machine. The stripping or cleaning
brush consists as usual of a series or row of bristles F which are fixed either
directly in the bar of the ordinary rubber H, which bears on the lower drawing
roller E of the drawing frame or other preparing machine, or in a wooden strip
fitted to such bar E. The brushes or bristles F are also set in the usual way at an
angle inclining upwards and inwards as particularly seen in figures 4 and 5, so
that they press against and partly pass through the gill pins d of each faller D as
it descends in its guides a at the front end of the machine and thus free the
fallers D of any loose fibre, "pouse," or dust which may adhere to them. This
loose fibre is freed from the brush F by the lower edge of the succeeding faller as it
drops, the lower.edge of the fallers being rounded to prevent wear of the brush.
The stripping or cleaning brush may be formed of a continuous strip of projecting
bristles F, and it may be fitted to slide in the framing of the machine instead of to
the rubber bar, or it may be suspended from the roller and kept to its work by the
rubber and spring.
The felt covered surface of the rubber or rubber board H which bears
longitudinally against the horizontal under drawing roller E, and the stripping
brush or bristles F fixed to the rubber are held up to their work or maintained in
position by the new or improved arrangement of lock springs or holders G, G,
which are fitted to the machine framing and bear on the under side of the rubber
bar H, one at each end, as shown in figure 3. These lock springs each consist of a
short vertical bracket or guide G against the front edge or side of which is fitted a
sliding bolt or bar G₁ which is held by a spiral spring G² surrounding its lower
end, and bearing or pressing between a shoulder g on the bolt, and a projecting
guiding eye g in the holding bracket G. A slot g' is formed in the fixed
bracket G near its upper end, through which a bolt or pin g³ is passed and screwed
into the sliding bar G', so that the bolt head retains the bar G₁ in position
while allowing it to move vertically.
A swivelling weighted catch G³ is jointed to the inner upper end of the fixed
bracket G, and this catch G³ retains or locks the spring bolt or bar when pulled
down by passing into the slot g², and bearing on the projecting pin or bolt head g³,
as indicated in figures 5, 6 and 7. For convenience of removing or adjusting the

page_text: pin or bolt the catch G³ is made with a knob g' to serve as a weight, and also
to catch on to the uppper end of the spring bolt and hold it down when
required. The upper end of the spring bolt G' is made flat to bear on the under
surfaco of the rubber board H, and is formed with a projecting pin g to enter a
hole in the rubber, or a pin in the rubber may fit in a hole in the bolt G. A
projecting horn G is formed on the spring bolt, by which this bolt is drawn down
by hand to be retained and locked by the weighted catch. C³ dropping into. tho
slot g and bearing on the pin g³ when it is desired to remove the rubber H and
brush F. When the rubber and brush are again fitted to the machine, the locking
catch G is released by hand, and the spring G allowed to act to raise the
rubber H and cause it to bear on the roller E, and also to bring the brush F into
the inclined cleaning position.
Figure 4 shows the lock spring holder G, G¹, holding the rubber Hup to the
drawing roller E, and figure 5 shows it depressed and held down by the catch G³,
so that the rubber and brush may be removed.
Figures 6 and 7 show the bracket part G cast or formed with fitting pieces
adapted for fitting the holdors to different machines or to different parts of the
machines.
Having now described and ascertained the nature of our said Invention, and the
manner in which the same is to be performed, we declare that what we claim as
our Invention is,-
First. The construction or arrangement and combination in a machine for
preparing flax, hemp, jute, and similar fibrous materials of a spring locking holder
or holders G, G', with the rubber board H, and cleaning brush F of such machines,
