Year: 1855

page_text: LETTERS PATENT to Lewis Harrop, Cotton Spinner, Samuel Barlow,
Overlooker, and Alexander Boyd, Machine Maker, all of Oldham; in the
County of Lancaster, for the Invention of "CERTAIN IMPROVEMENTS IN
SELF-ACTING MULES FOR SPINNING AND DOUBLING COTTON AND OTHER FIBROUS
MATERIALS."
Sealed the 10th June 1856, and dated the 29th December 1855.
PROVISIONAL SPECIFICATION left by the said Lewis Harrop, Samuel,
Barlow, and Alexander Boyd, at the Office of the Commissioners of.
Patents, with their Petition, on the 29th December 1855.
We, LEWIS HARROP, Cotton Spinner, SAMUEL BARLOW, Overlooker, and
ALEXANDER BOYD, Machine Maker, all of Oldham, in the County of Lancaster,
do hereby declare the nature of the said Invention for "CERTAIN IMPROVE-
MENTS IN SELF-ACTING MULES FOR SPINNING AND DOUBLING COTTON AND OTHER
FIBROUS MATERIALS" to be as follows:-
Our Invention relates, to the winding-on motion, and consists in attaching
the fulcrum of the radial arm and of the quadrant to the carriage. The
quadrant is worked by a pinion attached to a drum, which is worked by a
cord or band, the ends of which are secured to the framing of the headstock
or other convenient part. One end of the winding-on chain is connected in
the usual manner to the nut of the radial arm, and the other end is wound on.

page_text: a small barrel attached to the winding-on barrel, from which a chain, cord, or
band is taken to a barrel on the shaft of the twist pulley.
Another of our improvements in the winding-on motion is applicable to
Roberts' self-acting mules, and consists in connecting to the ordinary radial
arm, whose fulcrum is fixed to the headstock, a rail or arm jointed to the
carriage. The winding-on chain is attached to the radial arm as usual; this
chain is taken round a guide pulley at the front of the headstock, and then
secured to the winding-on drum on the tin roller coupling shaft. By this
arrangement the gearing usually employed in Roberts' mule is dispensed
with.
Our Invention also consists in dispensing with the twist pulley employed in
certain self-acting mules, and in working the drums or tiu rollers for driving
the spindles with one band.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Lewis Harrop, Samuel Barlow, and Alexander Boyd in the
Great Seal Patent Office on the 28th June 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, Louis
HARROP, Cotton Spioner, SAMUEL BARLOW, Overlooker, and ALEXANDER BOYD,
Machine Maker, all of Oldham, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of December, in the year of our
Lord One thousand eight hundred and fifty-five, in the nineteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Louis Harrop, Samuel Barlow, and Alexander Boyd, Iler special license
that we, the said Louis Harrop, Samuel Barlow, and Alexander Boyd, our
executors, administrators, and assigns, or such others as we, the said Louis
Harrop, Samuel Barlow, and Alexander Boyd, our 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 "CERTAIN IMPROVEMENTS IN SELF-ACTING MULES FOR SPINNING AND
DOUBLING COTTON AND OTHER FIBROUS MATERIALS," upon the condition (amongst
others) that we, the said Louis Harrop, Samuel Barlow, and Alexander
Boyd, our executors or administrators, by an instrument in writing under our
or their, or one of our or their hands and seals, should particularly describe

page_text: 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 we, the said Louis Harrop, Samuel Barlow, and
Alexander Boyd, do hereby declare the nature of our 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 our Invention consists in an improved combination of parts
for effecting the winding of the yarn on to the spindles during the running in
of the carriage.
And in order that our Invention may be fully understood and readily
carried into effect, we will proceed to describe the means pursued by us,
reference being had to the accompanying Drawing, and to the figures and
letters marked thereon..
Figure 1 is an elevation of the frame of a mule headstock and section of a
carriage, to which our improved winding-on motion is applied; and Figure 2,
a plan of the same. a is the frame of the headstock; b, the front drawing
roller; c, the shaft of the twist pulley d; e is one of the spindles supported in
the carriage f: The parts above enumerated, and all the others (excepting
those herein-after particularly referred to) requisite to complete the mule,-are
made in the usual manner. The brackets 9 of the carriage ƒ support tho
shaft h of the radial arm i, to which is cast or otherwise attached the quadrant
j. The pinion gears in the quadrant j, and is fast to the drum l, which is
fixed to a shaft revolving in bearings in the brackets g. The cord, chain, or
band m is passed around the drum l, and each end of the cord is made fast to
a stud projecting from the frame a. The radial arm i is provided in the usual
manner with a screw n and nut o, to which is attached one end of the
winding-on chain P, the other end of which is made fast to the small barrel
or scroll q, fast to the winding-on barrel r. The pieces q and r are fixed to a
shaft supported in the brackets &, fixed to the carriage. The cord, chain, or
band is made fast at one end to the winding-on barrel r, and at the other
end to the barrel u fixed to the shaft c of the twist pulley d. The mode of
operation is as follows:-When the carriage & moves to and fro, the cord,
chain, or band m causes the drum to revolve, thereby giving motion to the
pinion & and quadrant j; this motion makes the radial arm i assume a vertical
position as the carriage goes out, and a diagonal position, as shewn in
Figure 1, when the carriage is in. The nut o is near the fulcrum of the
radial arm at the commencement of building, the cop, consequently the

page_text: greater amount of winding-on chain is let off during the running in of the
carriage, and the greatest number of revolutions is imparted to the spindles
by the band passing over the twist pulley d, but the distance of the nut o to
the fulcrum of the radial arm is gradually increased until the cop bottom is
completed, by the attendant turning the handle v at the end of the screw n,
whenever the tension of the yarn becomes too great. We wish to remark,
that instead of the cord, chain, or band m and drum l, a rack and wheel may
be used for giving motion to the pinion k.
We stated in our Provisional Specification that "another of our improve-
ments in the winding-on motion is applicable to Roberts's self-acting mules,
" and consists in connecting to the ordinary radial arm, whose fulcrum is
"fixed to the headstock, a rail or arm jointed to the carriage. The winding-
"on chain is attached to the radial arm as usual; this chain is taken round
"a guide pulley at the front of the headstock, and then secured to the
"winding-on drum on the tin roller coupling shaft. By this arrangement
"the gearing usually employed in Roberts's mule is dispensed with. Our
"Invention also consists in dispensing with the twist pulley employed in
" certain self-acting mules, and in working the drums or tin rollers for driving
"the spindles with one band."
We wish it to be understood that we make no claim to the improvements
described in the above in part recited Provisional Specification; but what we
do claim is, the improved combination of parts, shewn and described in
reference to the accompanying Drawing, for winding the yarn on to the
spindles of mules.
In witness whereof, we, the said Louis Harrop, Samuel Barlow, and
Alexander Boyd, have hereunto set our hands and seals, this Twenty-
sixth day of June, in the year of our Lord One thousand eight
hundred and fty-six.
