The invention relates to gill frames for draw
ing flax, wool and other long staple ?bers for
. forming slivers or yarn in which the gill bars
are pushed forward along a controlled path as
distinct from faller bars carried forward by
screws.
.
The object of the invention is to provide means
by which the path of the push bars and the angle
of the gill pins thereon relative to the plane of
showing narrow collar which prevents end-wise
travel of the push bar.

2 and 6.
Fig. 9 is a side elevation of alternative shape‘

travel of the ?bers may be so controlled that as
the bars rise at the back and descend at the
front, the rising pins enter the sliver approxi
mately vertically or at right angles to the plane
of the ?bers and very close to the back roller
and the descending pins leave the sliver approxi
mately vertically or at right angles'to the plane
of the sliver and approach very close to the nip
of the front rollers before dropping clear of the
sliver and during the forward traverse of the
bars the distancebetween consecutive‘ rows of
20 pins, measured on the sliver line, is maintained
sliver in the nip, also guard or apron.

According to the invention the gill bars are
each constructed with journals to traverse a ?xed
path from back to front of the machine and with
two cranks having crank pins set at an angle
relative to one another to traverse ?xed cam
paths to control the relative angle of the gill
pins at di?erent positions in the traverse of the
bars.

The gill bars A1 are each constructed with a
journal 11 at each end to traverse a ?xed path A
carried by the frame or carriage plate E of the
machine extending between the back roller F and
the front roller G and leading with an incline
down which the bars slide to a driving sprocket
wheel W below the back roller F by which the
bars A1 are raised and propelled one bar push 35
ing the adjacent one forward. A collar a1 on
the bar ?ts between the teeth of the wheel W.
There are two driving wheels W one at each
side of the machine which engage and lift alter
40
nate bars.
The path A is preferably a casting secured to the
frame by bolts at2 with a removable gate or block
a3 to admit the ends of the gill bars A1. The
collar 111 also serves to prevent end-wise move
ment of the gill bar.
The ?xed path A for the gill bars A1 may be
varied from that shown in Fig. 3 to give a convex
curvature to the straight portion of the reach
and a similar curve to the return slope leading
to the driving wheel W. This reduces the sharp 50
ness of the curve during the descent of the bars
as shown in Fig. 9.
,
Each gill bar A is also constructed with or ?tted
with two cranks B1 C1 set at an inclination
to one another with crank pins b and 0 carried" 55
2
2,111,925
by the cranks B1 and C1 respectively. The crank
pins 1) and 0 while parallel to each other are
disposed in different though parallel planes and
operate in cam paths in different vertical planes.
The crank B1 is set at an angle of about 90° from
the line of the gill pin H and the crank C1 at
an angle of about 45° from the line of the same
gill pin H and the crank B1 (see Fig. 13a) or
parallel with the same gill pin H and at an angle
10 of about 90° from the crank B1 (see Figs. 8, 14a
and 14b).
The crank webs b1, 01 need not be at right angles
to each other as in an ordinary crank thereby en
abling the eccentricity of the crankpins b and c
15 to be much greater than if right angle crank webs
were used, the inclined cranks nesting into each
other.
The two cranks B1 C1 are preferably constructed
or forged at one end of .the gill bar A1 the crank
20 C1 being carried by and extending beyond the
crank pin b of the crank B1 as shown in Figs. 2, 6,
8,
and 141). Or the crank B1 may be forged at
one end of the gill bar A and the crank C1 at
the other end as shown in Figs. 13 and 13a.
25
Two ?xed cam paths or grooves B and C are
aflixed to the frame or carriage plate E of the
machine spaced apart in parallel planes. The
pin b of the crank B1 traverses the cam path B
and the pin 0 of the crank C1 traverses the cam
30 path C.
The crank B1 enters the path or groove B as
the bar is raised by the wheel W and continues
therein as the bar A1 traverses to the front roller
G and causes the pins H to assume a vertical po
36 sition and maintain a constant distance between
the row of pins H of adjacent bars A1 measured
on the sliver line.
The crank C1 transverses a ?xed cam path or
groove C a?ixed to the frame or carriage plate
40 E of the machine. The crank Cl enters the path
or groove 0 as the bar approaches the front
roller G and begins to descend and as the crank
B1 leaves the cam path B the crank C1 as it
moves down the cam path C maintains the de
45 scending pins H approximately vertical and at
right angles to the plane of the sliver and causes
them to approach very close to the nip of the
front roller G thereby reducing the distance or
space between the nip of the rollers and the point
50 where the descending pins I-I leave the sliver.
The crank C1 also controls the position or angle
of the pins H as the bars A1 descend the in
clined part of the path A towards the driving
sprocket wheel W.
55
The crank B1 and the cam path B cause the
pins H to assume on their forward traverse a
position leaning slightly backward in the reach.
This is useful for some types of sliver to prevent
it rising. The cam path B may however be dis
60 posed relatively to the ?xed path A of the bars
A1 that the pins H may travel forward at any
desired angle to the line of the sliver.
The -path B also controls the pins H as they
are rising maintaining them approximately par
65 allel as they enter the sliver.
As the bars A1
begin to descend and the pins H to drop out of
the sliver the crank B1 leaves the path B and be
comes inefiective and the crank C1 enters the
path C and takes control from this point on
70 ward.
As they descend the pins H are caused to lie
closely against the following bar thereby reduc
ing the distance between the last pin H1 and
the nip of the front rollers G G1 to a minimum.
75
As shown in Figs. 2 and 6 the two cranks B1
and C1 re on one end of each bar A1 but the
bars are set in the machine with the cranks alter
natively to right and left to provide room for
them requiring corresponding cam paths B and
C at both sides of the machine whereby one bar
is controlled from one side and the adjacent
bar from the other side of the machine. As
shown in Figs. 13 and 13a the crank B1 is at one
end of the bar A1 and the crank C1 at the other
end of the bar A1. With this construction of
bar the cam path B will be mounted at one side 10
of the machine and the cam path C at the other
side of the machine the cranks and cam paths
operating as above described.
When the cranks B and C are at one end of
15
the bar A the other end is made so short as not
to engage the teeth of a wheel W and discs D
are keyed on the driving shaft to support the
ends of the bars as they are raised and moved
forward by the driving wheel W at the other end.
The driving wheels W are set far back relative
to the back supply roller F, this ensures a verti
cal pinning of the sliver, the pins H of the rising
bars as controlled by the crank B1 and cam
path B are caused to penetrate the sliver ap
proximately vertically or at right angles or nearly
at right angles to itself. This enables a very
small pinning draft to be employed. A brush K
is mounted behind the wheel W or at any con
venient place to clean the pins H.
A sliver plate or bridge piece S (see Figs. 10, 3O
10a and 10b) is placed adjacent to the front
roller G between the last pin H1 and the nip of
the rollers to prevent the sliver lapping round
the pins H with an apron or shield S1 extending
downwards around the roller. It is carried from
the ordinary ?oating conductor or some other
part of the machine.
It may run continuously
from one side of the head to the other or it
may be in separate pieces for one, two or more
slivers.
As shown in detail in Figs. 11 and 12 the gill
gars A1 are constructed with the pins H set
thereon forward of the centre upon the front
or the leading edge the pins being approximately
tangential to the bar instead of radial as is
customary in this type of gill bar. Fig. 11 shows
four out of several different combinations of pin
positions and Fig. 12 four different methods of
securing the pins in position.
Such as at e by
drilled holes, at f by notches or solder, at g by
?at on bar and pins soldered on and at h by a
brass gill stock riveted to the bar. To prevent
the gill pins H on one bar from pushing against
the bar in front of it, projections 7' are soldered
or otherwise fastened thereto at intervals between
the bars, see Figs. 15 and 15a.
