page_text: LETTERS PATENT to Robert Halliwell, of Bolton-le-Moors, in the County
of Lancaster, Manager to Messieurs Benjamin Dobson and Edward
Barlow, of the same place, Machine Makers, for the Invention of "CERTAIN
IMPROVEMENTS IN THE MACHINES FOR SPINNING, CALLED SELF-ACTING MULES.'
- A communication.
Sealed the 3rd October 1856, and dated the 4th April 1856.
PROVISIONAL SPECIFICATION left by the said Robert Halliwell at the
Office of the Commissioners of Patents, with his Petition, on the 4th
April 1856.
I, ROBERT HALLIWELL, of Bolton-le-Moors, in the County of Lancaster,
Manager to Messieurs Benjamin Dobson and Edward Barlow, of the same
Place, Machine Makers, do hereby declare the nature of the said Invention.
for CERTAIN IMPROVEMENTS IN THE MACHINES FOR SPINNING, CALLED SELF-ACTING
MULES, to be as follows:-
This Invention consists of an improved combination of parts for regulating
the lifting of the copping faller when the carriage arrives at or near the
drawing rollers. To the copping faller shaft is fixed a quadrant, to which is
fastened one end of a weighted chain, which is taken over a pulley; this pulley
is mounted on a lever, and to it is fixed a toothed wheel with a portion of the

page_text: teeth left out in one place. When the carriage arrives near the drawing
rollers, the click by which the lever is supported is liberated, and the lever in
dropping allows the toothed wheel above mentioned to drop into gear with a
wheel fixed on the shaft, from which the spindles are driven. The lever with
the chain pulley and wheel are raised when the carriage is out by an elbow
lever acting against a fixed stud. When the stretch is finished, the faller in
descending lowers the weight, and during the going in of the carriage tho
faller has risen to the nose of the cop; the catch by which the lever is held up
is then liberated, and the lever drops until the two wheels come into gear; the
faller is now unlatched, but cannot rise till the driving strap is moved on to
the fast pulley, which causes the spindles to revolve.
By making the quadrant on the faller shaft in two parts, and varying their
position, the number of coils of the spindles can be regulated. By the time
the faller has risen to its highest point, the blank space in one of the wheels
comes opposite the other wheel, and the wheels remain in these positions until
the carriage is ready for running in at the subsequent stretch. The carriage
is allowed to run into the beam and make the requisite changes of the
cam shaft; &c. before the driving strap is allowed to go on the fast pulley by
means of a cam and spring or weight attached to the strap fork, thereby
causing the spindles to commence revolving slowly, and the fallers to rise at
the same time.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Robert Halliwell in the Great Seal Patent Office on the
4th October 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
HALLIWELL, of Bolton-le-Moors, in the County of Lancaster, Manager to
Messieurs Benjamin. Dobson and Edward Barlow, of-the same Place, Machine
Makers,.send greeting.

page_text: 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 CERTAIN IMPROVEMENTS IN
THE MACHINES FOR SPINNING, CALLED SELF-ACTING MULES, (a communication froni
a foreigner residing abroad), upon the condition (amongst others) that I, the.
said Robert Halliwell, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should particularly
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 Robert Halliwell, 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):-
:
The nature of the Invention, communicated to me, consists in an improved
combination of parts for regulating the lifting of the copping faller when the
carriage arrives at or near the drawing rollers; and in order that this Inven-
tion may be fully understood and readily carried into effect, I will proceed to
describe the accompanying Drawing, reference being had to the letters and
figures marked thereon. a represents the, framing of the headstock of an
ordinary self-acting mule to which these improvements are applied; b is part
of the rim pulley shaft, on which is fixed the driving pulley. 6'; 62 is the strap
guide; c is part of the cam shaft; d, a section of the carriage; e, the copping.
faller shaft; f, the counter faller shaft; g, the shaft from which the spindles
are driven; and h, the spindles. The foregoing parts, and all those requisite
to complete the mule, which are not particularly referred to hereafter, are
made in the usual manner. To the copping faller shaft e is fixed a bush and
plate e', to which is bolted the quadrant or segment plate for the chain i.:
One end, of this chain is secured to the quadrante, and to the other end is
attached the-weight . The object of making the quadrant 'e and bush e¹ in
two pieces,' connected by bolts, is to be enabled to vary the radius of the
quadrant,, whereby the number of coils of the yarn round the spindles can be
regulated with facility. The chain i is taken round the guide pulley j, and
then over the toothed pulley k attached to the spur wheel k', which is made
with a portion of the teeth omitted or removed in one place. The pulley k
and wheel k' are mounted on a stud fixed in the lever 1, whose fulcrum is at l'.
The wheel is placed immediately above the wheel m³, fixed on the shaft g,

page_text: from which the spindles are driven in the usual manner.
Near the extremity
of the lever is suspended the catch , which is provided with a counterweight
to hold it against the stud n and the link o, jointed below to the horizontal
arm of the elbow lever p. The mode of operation is as follows:-The
Drawing represents the various parts in the positions they occupy when the
carriage, in going out, has performed about half its stretch; the lever is down,
but the blank space of the wheel k¹ being just opposite the wheel m³, allows
the wheel m¹ to revolve without giving motion to the wheel k; the weight i'
is raised up; as soon as the carriage is near the end of its stretch, the vertical
arm of the elbow lever p comes against the stud q, thereby raising the lever
sufficiently to allow the catch to take hold of the stud n; this raising of the
lever allows the wheel ¹ to revolve without touching the wheel m¹, when the
copping faller in descending allows the weight ¹ to drop, and thus to give
motion to the toothed pulley k and wheel k¹, the amount of this motion varying
according to the length of the cop on the spindles. The parts remain in those
positions while the carriage is running in, during which time the faller has
again risen to the nose of the cop; when the carriage arrives near the drawing
rollers, the catch comes against the stud r, thereby unlatching the lever
and allowing the wheels k¹ and m¹ to drop into gear; the faller is at this time
unlatched, but it cannot rise until the driving strap is moved partly on to the
fast pulley b', thereby causing the spindles to revolve slowly; this moving of
the driving strap is effected by the projection d' on the carriage unlatching the
latch c', which liberates the elbow lever c, and allows the weight c* to draw
the strap partly on to the fast pulley 6', the cam c¹ on the cam shaft being
made with a recess to admit the bowl on the elbow lever c, which is jointed
to the stud c³. The slow motion thus imparted to the pulley b' and shaft b
is transmitted in the usual manner to the shaft g and wheel m', and the
wheels m¹ and ¹ being now in gear, the copping faller is allowed to rise in
proportion to the number of revolutions given to the spindles. When the
faller has risen to its highest point, the blank space in the wheel k¹ comes
opposite the wheel m', and the driving strap is then allowed to go entirely on
the pulley b, as shewn in the Drawing; the wheels and m¹ remain in these
positions until the carriage is ready for running in at the subsequent stretch.
Having thus described the nature and particulars of the Invention, as com-
municated to me, I wish it to be understood that I do not limit myself to the
precise details herein set forth, but what I claim is, the improved combination
of parts shewn and described for regulating the lift of the copping faller.
Secondly, making the quadrant on the faller shaft in two parts, for the
purposes described; and,

page_text: Thirdly, the wheel marked k², when applied in combination with machinery
for regulating the lift of the copping faller.
In witness whereof, I, the said Robert Halliwell, have hereunto set my
hand and seal, this Third day of October, One thousand eight hundred
and fifty-six.
