AN IMPROVED MODE OF DRIVING THE SPINDLES USED IN MACHINES FOR SPINNING, DOUBLING, AND WINDING FIBROUS MATERIALS.
Year: 1873

page_text: LETTERS PATENT to Richard Shaw, of Higher Walton, near Preston,
in the County of Lancaster, for the Invention of "AN IMPROVED
MODE OF DRIVING THE SPINDLES USED IN MACHINES FOR SPINNING, DOUBLING,
AND WINDING FIBROUS MATERIALS.'
"
Sealed the 10th October 1873, and dated the 10th April 1873.
PROVISIONAL SPECIFICATION left by the said Richard Shaw at the
Office of the Commissioners of Patents, with his Petition, on the
10th April 1873.
I, RICHARD SHAW, of Higher Walton, near Preston, in the County
of Lancaster, do hereby declare the nature of the said Invention for
"AN IMPROVED MODE OF DRIVING THE SPINDLES USED IN MACHINES FOR SPINNING,
DOUBLING, AND WINDING FIBROUS MATERIALS," to be as follows:-
This Invention relates to spindles the wharves of which communicate
by bands or straps with a driving cylinder or drum, each band or strap
in the machines at present in use passing partly round the wharve in an
angular direction to and from the cylinder or drum.

page_text: My improvements consist in employing at the front of the wharves a
roller working in stationary or moveable bearings, and passing each
band or strap from the cylinder or drum entirely around the circum-
ference of the wharve, and partially round the roller to the cylinder or
drum.
As the band passes round the entire circumference of the wharves the
friction is more equalized than at present, and they may be made of
smaller diameters, and the spindles driven at a quicker speed.
In throstles and other machines in which the bobbins have to be
doffed I place the additional roller in bearings worked by cranks or :
eccentrics and handles so that the bands can be slackened to allow the
bobbins to be removed and replaced, and afterwards tightened.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Richard Shaw in the Great Seal Patent Office
on the 10th October 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
SHAW, of Higher Walton, near Preston, in the County of Lancaster,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of April, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Richard Shaw, Her special licence
that I, the said Richard Shaw, my executors, administrators, and
assigns, or such others as I, the said Richard Shaw, 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 "AN IMPROVED MODE
OF DRIVING THE SPINDLES USED IN MACHINES FOR SPINNING, DOUBLING, AND
WINDING FIBROUS MATERIALS," upon the condition (amongst others) that I,
the said Richard Shaw, my executors or administrators, by an instru-

page_text: ment in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Inven.
tion, 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 Richard Shaw, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Figures on the accom-
panying Sheet of Drawings, and to the letters of reference marked
thereon (that is to say) :-
:-
This Invention relates to spindles the wharves of which communicato
by bands or straps with a driving cylinder or drum, each band or strap
in the machines at present in use passing partly round the wharve in an
angular direction to and from the cylinder or drum.
My improvements consist in employing at the front of the wharves a
roller working in stationary or moveable bearings, and passing each
band or strap from the cylinder or drum entirely around the circum-
ference of the wharve and partially round the roller to the cylinder or
drum.
As the band passes round the entire circumference of the wharves
the friction is more equalized than at present, and the wharves may
be made of smaller diameters, and the spindles driven at a quicker
speed.
In throstles and other machines in which the bobbins have to be
doffed I place the additional roller in bearings worked by cranks or
eccentrics and handles, so that the bands can be slackened to allow the
spindle motion to be reversed, the flyers unscrewed, and the bobbins
doffed.
Figs. 1 and 2 on the accompanying Sheet of Drawings are views of
the application of my additional roller to the front of the wharves of
spinning mules, one of the spindles being marked a, its corresponding
wharve b, the additional roller c, and the driving drum d.
Having now described the nature and particulars of my said Invention,
and the manner in which the same is to be performed, I desire it to be
understood that I claim the improved mode of driving ths spindles used

page_text: in machines for spinning, doubling, and winding fibrous materials,
as herein described and illustrated on the accompanying Sheet of
Drawings.
In witness whereof, I, the said Richard Shaw, have hereunto
set my hand and seal, this Third day of October, in the year of t
our Lord One thousand eight hundred and seventy-three.
Signed, sealed, and delivered by the
before-named Richard Shaw, in
the presence of
JOHN BRIERLEY.
RICHARD SHAW. (L.S.)
