[A communication to him
This invention relates to the arrangement of the rollers in spinning machines.
Heretofore the intervals between the rollers in spinning machines, whether self
acting or driven by straps, were so arranged, that the "line of contact" along
which the worsted (which I hereinafter term "the spool") moves between the
rollers was a straight line and followed either a horizontal or an oblique course.
I hereinafter term this line the "line of intervals." This arrangement of a straight
line of intervals has various defects, whether the line follows a horizontal or an
oblique course
Some of the ordinary defects of the straight " line of intervals" respecting self
acting rollers or rollers driven by means of straps, are, that in a horizontal course
the spool has too little contact with the intermediate grooved rollers, that is, with
the rollers which are situated between the first and last row of rollers, and the
said spool is not held firm enough, the result of which is that irregular intervals
are caused, this happens especially with the " pressure rollers" which have not a
soft covering and work only by their own weight as is the case in worsted spinning
machines.; and in an oblique course the work is done in a manner still more
defective on account of the awkwardness of the position, the unsafe bearings
resulting therefrom, and the manner of working the pressure rolls of the second
[Price Gd1

page_text: row of rollers and of all the following rows, however many there may be; the
less the weight of these rolls, the more defective being the work produced.
The working is especially deficient in machines where the pressure rollers of the
second row or subsequent rows of rollers, however many there may be, work by
their own weight and press on the spool, receiving their motion only from the
grooved rollers beneath. The shafts of these pressure rollers suffer from their
weight and are subjected to a strong friction from the sides of the slots or guides
which they move, this friction prevents a regular revolving of the said pressure
rollers and consequently occasions irregular intervals.
Some of the special defects of the straight line of intervals, when rollers are
driven by means of straps, are that as the spool comes from between the second
row of drawing rollers it is pushed forward, especially when the sliver is not much
twisted and this occurs without any rotatory movement whatever and without
the spool being tangential to the rollers. When the spools are not tied and are
too weak to withstand the tension which is created by the process, a good many
breaks and slips occur and some of the outward filaments are severed so that
nothing is left but a weak sliver full of irregularities.
According to the present invention all these defects are remedied by arranging
the rollers out of line which I hereinafter term the broken "line of intervals";
by means of this arrangement the spools are caused to twist faster but yet
sufficiently by contact with the grooved intermediate rollers; the pressure rollers
in the first row of drawing rollers are caused to lean as far towards the spindle
as is necessary for the twisting of the sliver to take place without obstruction
until the spools issue from the drawing rollers. This was not possible with the
straight "line of intervals" following a horizontal course, whilst the distance
between the line of contact of the drawing rollers and that of the second row of
rollers was too great, which caused irregularities in the slivers, and notwithstanding
the fact that the pressure rollers are brought forward, the pressure rollers belonging
to the second row of rollers and those of all the following rows will be perpen-
dicular to the grooved rollers which was impossible in the case of a straight "line
of intervals "following an oblique course.

WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, and Co, Patent
"IMPROVEMENTS RELATING TO THE
Agents, Southampton Buildings, London,
a communication to
ne from abroad by Ernest Mehl, of Augsburg, in the Empire of Germany
ROLLERS OF MACHINES FOR SPINNING TEXTILE MATERIALS.'
This invention relates to the rollers of spinning machines and comprises the
novel arrangement hereinafter described
In the accompanying drawing
Figure 1 is a side view showing the rollers arranged in a straight line
horizontally
Figure 2 is a similar view showing the rollers arranged obliquely
Figure 3 is a view hereinafter described, and
Figure 4 shows the arrangement of the rollers according to this invention.
Heretofore the rollers of spinning machines, whether self-acting or driven by
straps, were so arranged, that the points of contact of the several pairs of rollers
between which the material moves, were in a straight line hereinafter termed the
"line of intervals" and arranged as in Figure 1 horizontally, or as in Figure 2
obliquely. This arrangement of a straight line of intervals has various defects,
Some of the ordinary
whether the line follows a horizontal or an oblique course.
defects of the straight " line of intervals," respecting self acting rollers or rollers
driven by means of straps are, that in the horizontal arrangement the material
has too little contact with the intermediate grooved rollers, that is to say with the
rollers which are situated between the first and last pairs of rollers, and the said
material is not held firm enough, the result of which is that irregularities are
caused; this happens especially with the "pressure rollers" which have not a soft
covering and work only by their own weight as is the case in worsted spinning
machines; and in an oblique arrangement the work is done in a manner still more
defective on account of the awkwardness of the position of the pressure-rollers and
the manner of operating the same; and the less the weight of these rolls the more
defective is the work produced.
The operation is especially defective in machines where the pressure-rollers of
the second row or subsequent rows of rollers, however many there may be, work
by their own weight and press on the material, receiving their motion only from
the grooved rollers beneath. The shafts of these pressure-rollers suffer from the
weight and are subjected to a strong friction from the sides of the slots or guides
in which they move. This friction prevents a regular rotation of the said pressure-
rollers and consequently occasions irregularity.
Some of the special defects of the straight line of intervals, when rollers are
driven by means of straps, arise from the fact that as the material comes from
between the second row of drawing rollers it is pushed forward from a to b as
shown in Figure 1 especially when the sliver is not much twisted and this occurs
without any rotatory movement whatever and without the material being tangential
to the rollers. When the fibres are not tied and are still too weak to withstand
the tension many breaks and slips occur and some of the outer filaments are
severed so that nothing is left but a weak sliver full of irregularities
Figure 3 is a view shewing the untwisted portion of the sliver between the
points a and b.
According to the present invention all these defects are remedied by arranging

page_text: the rollers out of line with each other as shown at A. B. C. D, Figure 4. By means
of this arrangement the fibres are caused to twist faster, but yet sufficiently, by
contact with the grooved and intermediate rollers B and C, and the pressure rollers
in the first row of drawing rollers are caused to incline as far towards the spindle
as is necessary to enable the twisting of the sliver to take place, without obstruc-
tion, up to the point at which it issues from out of the drawing rollers. This was
not possible with the straight "line of intervals" following a horizontal course,
whilst the distance between the line of contact of the drawing rollers and that of
the second row of rollers was too great, which caused irregularities in the slivers,
and notwithstanding the fact that the pressure rollers are brought forward, the
pressure rollers belonging to the second row of rollers and those of all the following
rows will be perpendicular to the grooved rollers which was impossible in the
case of a straight "line of intervals "following an oblique course.
Having thus fully described the said invention as communicated to me by my
foreign Correspondent, and the manner of performing the same, I wish it understood 1
that I Claim:-
Arranging the rollers of a spinning machine substantially as described with
reference to Figure 4 of the drawing for the purposes specified.
In witness whereof I the said William Robert Lake have hereunto set my hand
seal [sic] this Twenty seventh day of October in the year of our Lord One thousand 2
eight hundred and eighty three.
