İ; HENRY BERNOULLI BARLOW; of the City of Manchester, Patent Agent,
5 do hereby declaré the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY FOR SPINNING AND DOUBLING," a communication to me from abroad
by Heinrich Zwanziger and William Henry Rhodes, both of Chemnitz; in the
Kingdom of Saxony, to be as follows:-
This Invention is applicable to the machines for spinning and doubling,
known as self-acting mules, in which the spindles are made to recede from
and approach the drawing rollers. In ordinary machines the carriage with
the spindles traverses to and fro horizontally. Now this' Invention consists in
making the carriage and the drawing rollers move up and down diagonally,
and in making the machine either single or double; by this means, and by
the improved. arrangement of the component parts of the machine, the work

page_text: of the tenters can be performed more expeditiously and with less inconvenience
than in mules of the present construction; a great saving in space is also
effected. The roller beam and the carriage for the spindles aro each con-
nected to a rack, and these racks gear into opposite sides of a pinion which
is driven by a mangle wheel; in revolving this mangle wheel causes the
roller beam and the spindles to approach and recede from each other. The
driving shaft is provided with the usual self-acting and other pulleys, with
the backing-off friction box, the rim band pulley, and the pinions for driving
the various parts of the machine. The front drawing roller is driven by a
diagonal shaft with a groove in which fits a key fixed-in a mitre pinion that
slides up and down with the roller beam. The radial arm is jointed to a
stud fixed in the frame supporting the spindles; this radial arm has a screw
and nut as usual for governing the length of the backing-off chain; at the
end of the radial arm is a bowl which acts on a bent bar. The yarn is guided
on to the spindles by means of faller and counterfaller wires, the position of
which is governed by a faller motion and a winding-on motion, both of which
aro adapted to the peculiar arrangement of the other parts of the machine.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Bernoulli Barlow in the Great Seal Patent Office on
the 20th September 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
BERNOULLI BARLOW, of the City of Manchester, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of March, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Henry Bernoulli Barlow, Her special license that I, the said Henry
Bernoulli Barlow, my executors, administrators, and assigns, or such others as
J, the said Henry Bernoulli Barlow, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time, and at all
times thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN MACHINERY FOR SPINNING AND DOUBLING," a communication to me from abroad.
by Heinrich Zwanziger and William Henry Rhodes, both of Chemnitz, in the
Kingdom of Saxony, upon the condition (amongst others) that I, the said

page_text: Henry Bernoulli Barlow, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should par-
ticularly describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed in
the Great Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Henry Bernoulli Barlow, do hereby
declare the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement (that is to say) :-
This Invention is applicable to the machines for spinning and doubling
known as self-acting mules, in which the spindles are made to recede from
and approach to the drawing rollers. In ordinary machines the carriage
with the spindles traverses to and fro horizontally, while the beam which
supports the drawing rollers remains stationary. Now this. Invention consists
in making the carriage and. the drawing rollers alternately to move to and
from each other diagonally, and in making the machine cither single or
double; by this means, and by the improved arrangement of the component
parts of the machine, the work of the tenters can be performed more expe-
ditiously and with less inconvenience than in mules of the present construction,
and a great saving in space is also effected.
And in order that this Invention may be fully understood and readily
carried into operation I will proceed to describe the two accompanying Sheets
of Drawings, reference being had to the figures and letters marked thereon.
On Sheet 1, Figure 1 is an end view, and Figure 2 a front view of a
machine for spinning and doubling, constructed according to this Invention."
a is the driving shaft, supported as usual in fixed bearings in the headstock;
on the shaft a are the three pulleys 9, 9³, and g³, the latter is keyed on the
shaft a; the pulley 9¹ is loose on the shaft a, but fast to the pinion r, gearing
into the carrier wheel which drives the wheel t keyed on the shaft ..
To the wheel t is fixed the mitre wheel t¹ gearing into the wheel m¹; loose on
the diagonal shaft w, but connected to it when required by the clutch box w
at the upper end of the shaft w, is keyed the mitre wheel w³, gearing into
the wheel h¹ on the front roller h. On the shaft a is fixed a pinion y gearing
into the carrier wheel y¹; to this carrier is fixed the pinion y gearing into
the wheel m loose on the shaft l; the clutch box on the wheel m takes into
the clutch box m² fixed to the wheel m³ keyed on the shaft 1. The wheel m
gears into the carrier-m³ fast to the change pinion m* gearing into the wheel
vfixed on the, shaft working in the swing lever to this shaft.is also

page_text: fixed the pinion gearing into the reversible wheel c; the teeth c¹ on
-the circumference of the reversible. wheel gear into the, wheel b¹ fixed to
the shaft . On this shaft aro pinions gearing into the racks d and e,
shewn by dotted lines in Figure. 2; to. the upper end of the; racks; d is fixed
the roller beam d for supporting the drawing rollers h; and the rovings, and
to the lower end of the racks e are fixed. the angle rails e¹ for supporting the
spindles.f; the faller and counterfaller shafts i and i, the tin roller shaft is, and
the winding-on barrel shaft are made as usual and supported in brackets
connected to the racks e. The radial arm zis hinged on the stud . fixed in
the rack e; at the outer end of the radial arm is a bowl bearing upon the
fixed guide plate. The winding-on chain is attached to the nut of the
screw of the radial arm as usual, and after passing around a guide pulley is
coiled around the winding-on barrel on the shaft. The backing-off chain a,
the copping rail, the faller lock lever.a, and the other parts of the copping
motion are made in the usual manner, but modified, to suit the peculiar
arrangement of the other parts of the machine.. The backing off and the
requisite changes are performed by a cam shaft of the usual construction,
.or by the improved machinery. hereafter described. The rod or wire is extends
across the machine immediately behind the yarns, and it is placed about mid-
way between the front drawing roller and the spindles; this rod or wire
prevents or reduces the vibration of the yarn while the twist is put in, and; the
injury, to the adjacent yarns when an end breaks..
The mode of operation is as follows, and, the Drawing represents the parts
in, the positions, they occupy when the twist has been given:The pinion v
in revolving will now gear into the internal. portion of the reversible wheel c,
thereby, giving motion to the shaft 6 in the proper direction for causing, the
drawing rollers and the spindles to approach each other, the winding-on
taking place at the same time; when the roller beam d is, down, as shewn
by dotted lines; and the spindles fare raised, the pinion has arrived, at the
external teeth of the reversible.wheel c; thus reversing the direction of motion
of the shaft b, and causing the drawing rollers and; spindles to recede from
each other during the operation of spinning and twisting,
These improved machines for. spinning and doubling may be used either
single, as shewn in the. Drawing above described, and in Figure 3 on Sheet 2,
.or. they may be double, as shewn in Figure 4.; by this improved arrangement
of the component parts of the machine the work of the tenters can be per-
formed more expeditiously and with less.labour and inconvenience than in the
machines for spinning commonly called. mules, and, a great, saving of space, is
also effected. Figure 5 is a front view, Figure 6, a section, and, Figure 7,

page_text: another front.view, and Figure 8, a side view of a revolving box: of variable
motions for producing the changes of motions necessary for spinning and
doubling..
A is a shaft corresponding to the, ordinary cam shaft situated in the position
indicated by the dotted circle A, in Figure 1; to the shaft A is keyed the
cam. B, to which are jointed the levers C and D; each of these levers is
provided with an antifriction bowl acting against the four swells of the
internal cam E; this cam is stationary, and it is provided with a bush
fixed to the framing of the headstock. The bowls of the levers C and D are
held in contact with the swells of the internal cam by the spring F. The
lever C is made with a double catch taking, when required, into the teeth of
the internal ratchet wheel G, which is cast or fixed to the spur wheel H
gearing into the backing-off wheel a' on the shaft a, see Figures 1 and 2. As
soon as the cam shaft is liberated by the action of the escapement lever in
the usual manner the dwells on the internal cam E acting on the bowls
on the levers C and D allow the double catch to drop into gear with the
internal ratchet wheel G, as shewn in Figure 7 ; but as soon as the cam shaft
has performed one-fourth of a revolution the double catch is drawn out of
gear with the internal ratchet wheel G, as shewn in Figure 5. In the accom-
panying Drawing I have shewn four dwells on the internal cam E, as
required in spinning wool, but it is evident that the said cam may be made with
three or two dwells according to the number of changes required.
Having thus stated the nature of the Invention, and described the manner
of performing the same, as communicated to me by the within-named Heinrich
Zwanziger and William Henry Rhodes, wish it to be understood that I am
aware that attempts have been made to construct mules in which the roller
beam and drawing rollers have a vertical or diagonal up-and-down motion
imparted to them, and the spindles move diagonally or in the arc of a circle.
I therefore make no claim to moving the roller beam and spindle carriage,
except in the manner above described and shewn in the accompanying
Drawings; but what I claim is,―
i
First, the general arrangements and combinations of the parts forming
a self-acting machine for spinning and doubling, as shewn and described.
Secondly, the simultaneous approaching and receding actions of the drawing
rollers and the spindles and their accessories in diagonal lines for producing
the stretch, as shewn and described.
Thirdly, the application of the wire or rod marked at about the centre of
the length of the stretch, for the purposes described.
And, lastly, the revolving box, shewn and described in reference to Figures 5,

page_text: 6, 7, and 8, for effecting the changes of motion in machines for spinning and
doubling.
In witness whereof, I, the said Henry Bernoulli Barlow, have hereunto
set my hand and seal, this Eighteenth day of September, One thousand
eight hundred and sixty-six.
