WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. 'IMPROVEMENTS IN MACHINERY FOR SPINNING
WOOL AND OTHER FIBROUS MATERIALS." [A communication from abroad by
John Abbott, of Philadelphia, Pennsylvania, United States of America].
This Invention relates to improvements in mules and jacks adapted for spinning
woollen yarns and wool carded cotton yarns, and which may be applied to hand
or self operating machines.
Heretofore slubbings or slivers from which. yarn is spun on woollen mules and
jacks have been delivered through one set of rollers, and the draft or drawing of
the fibres has been between the rollers and the spindles.
The object of this Invention is to wholly or partially draw and reduce the
slubbings between two or more sets of rollers by which I am enabled to spin fine
yarn from heavy and coarse slubbings, and produce a greater length of yarn and
better thread from the same material and in the same time than has been practicable
heretofore when using one set of rollers.
The said Invention comprises the employment of a front line of rollers and one
or more lines of rear rollers rotating at different degrees of speed whereby slubbing
may be reduced directly from the card without intermediate preparation.
It also comprises arranging the upper and lower rollers at an angle, by means of
which the slubbing is caused to move in a direct right line with the bearing centre
of the rollers.
Also adjustably mounting the rear rollers whereby they may be set nearer to or
farther from the front line of rollers, and thus adapt the bearing centres of said
rollers to the length of staple to be drawn.

page_text: In carrying the said Invention into practice rear rollers are arranged one above
the other, the upper one being mounted on a stand which is adjustably secured to
the frame by means of screws which pass through slots in the stand and are fitted
to the frame, and the lower roll is mounted on a stand which is also adjustably
secured to the frame by means of screws.
If desired another line of rollers may be employed, and they are mounted on the
aforesaid stands.
The upper rollers of the several lines rest freely on the lower rollers thereof, and
are driven by frictional contact therewith. The lower rollers are geared or driven
in such manner that they rotate at different degrees of speed.
A wheel on the front roller may be changed for varying the draft as desired, and
if desired all of the draft may be between the two lines or three lines of rollers, or
it may be distributed between said rollers and the carriage, as will be clearly under-
stood by spinners.
By means of the aforesaid adjustable bearings or stands for the rear rollers the
latter may be set nearer or farther from the front line of rollers, and thus adapt the
bearing centres of said rear rollers to the-length of different kinds of staple to be
drawn.
The rollers of the rear line may be in "threes," similar to the front line of rollers,
or in "twos."

WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN MACHINERY FOR SPINNING
WOOL AND OTHER FIBROUS MATERIALS." A communication from abroad by John
Abbott, of Philadelphia, Pennsylvania, United States of America.
This Invention relates to improvements in mules and jacks which are adapted
for spinning woollen yarns and wool carded cotton yarns, and which may be applied
to hand machines or self operating machines..
Heretofore slubbings or slivers from which yarn is spun on woollen mules and
jacks have been delivered through one set of rollers, and the draft or drawing of
the fibres has been between the rollers and the spindles.
The object of this Invention is to wholly or partially draw and reduce the
slubbings between two or more sets of rollers by which I am enabled to spin fine
yarn from heavy and coarse slubbings, and produce a greater strength of yarn and
better thread from the same material and in the same time than has heretofore
been practicable when using one set of rollers.
The said Invention comprises the employment of a front line of rollers and onc
or more lines of rear or back rollers rotating at different degrees of speed, whereby
the slubbing may be reduced directly from the card without intermediate
preparation.
It also comprises the arranging of the upper and lower rollers at an angle, by
means of which the slubbing is caused to move in a direct right line with the bearing
centre of the rollers...
Also adjustably mounting the back rollers so that they may be set nearer to or
farther from the front line of rollers, and thus adapt the bearing centres of the said.
rollers to the length of staple to be drawn.
In the accompanying Drawing,-
Figure 1 is a vertical section of improved machinery constructed according to
this Invention; and
Figure 2 is a plan or top view of the same.
Similar letters indicate corresponding parts in both Figures.
A represents one of the frame ends of a mule or jack, and B, B', a front line or
pair of rollers mounted thereon; C represents the drum; D, the sliver spool, and
D', the spindle carriage; all of which are operated substantially in the same manner
as usual in hand or self-acting machines.
E, E', represent another line of rollers or back rollers arranged one above the
other, the upper roller E being mounted on a stand F, which is adjustably secured
to the frame A by means of screws F¹ which pass through slots in the staud and
are fitted to the frame, and the lower roll E¹ is mounted on a stand G which is also
adjustably secured to the frame A by means of screws G¹.
If desired another line of rollers E, E, may be employed and respectively
mounted on the aforesaid stands F, G.
The upper rollers of the several lines rest freely on the lower rollers thereof, and
are driven by frictional contact therewith. The lower rollers are geared or driven
in such a manner that they rotate at different degrees of speed the several rollers
rotating in the direction of the arrows.
The operation of the above described mechanism is as follows, that is to say
The woollen or cotton slubbings are delivered by the drum C from the spool D,
and pass between the rollers E, E, and E', E, and thence to the front line of
rollers B, B', between and from which they pass and are delivered to the spindle of

page_text: 4
the carriage D', by which the slivers are twisted and spun into yarn and wound on
a bobbin or tube on the spindle. By the employment of the gearing for the rollers,
as shewn in the Drawing, the front line of rollers will run one fourth faster than the
back rollers, and the draft is three to four, that is to say, the back rollers deliver
three inches of slubbings, to the front rollers which will draw it into four inches
and deliver it to the spindles on the carriage, and if desired_the spindle carriage
may still further draw the slivers as they are being twisted into yarn.
The wheel on the front roller may be changed for varying the draft as desired,
and if desired all of the draft may be between the two lines or three lines of
rollers, or it may be distributed between said rollers and the carriage, as will be
clearly understood by spinners.
By means of the aforesaid adjustable bearings or stands for the rear or back
rollers the latter may be set nearer to or farther from the front line of rollers, and I
thus adapt the bearing centres of said back rollers to the length of different kinds of
staple to be drawn.
The upper and lower rollers are set at an angle to each other, as shewn, whereby
the slubbing is caused to move in a direct right line with the bearing centre of the
rollers.
The rollers of the back line may be in "threes" similar to the front line of
rollers, or in "twos," as shewn in the Drawing.
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
that I claim,
First. The combination with the front line.of rollers of one or more lines of
back rollers rotating.at different degrees of speed, substantially as above set forth
and for the purpose specified.
Second. The front line of rollers in combination with one or more lines of back
rollers, and with the sliver-spool, drum and spindle carriage, substantially as and
for the purpose specified.
Third. The upper and lower rollers set at an angle to each other, whereby the
slubbing is caused to move in a direct line with the bearing centre of the rollers,
substantially as above set forth and for the purpose specified.
Fourth. The combination with the front and back lines of rollers of the adjustablo
bearings or stands, substantially as and for the purpose set forth.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Twenty fifth day of February, in the year of our Lord
One thousand eight hundred and eighty.
