Year: 1853

page_text: LETTERS PATENT to Edward Oldfield, of the firm of Messieurs
Oddy, Robinson, and Company, of Salford, in the County of
Lancaster, Machine Makers, for the Invention of "IMPROVEMENTS
PROVISIONAL SPECIFICATION left by the said Edward Oldfield
at the Office of the Commissioners of Patents, with his Petition,
on the 6th December 1853.
I, EDWARD OLDFIELD, of the firm of of Messieurs Oddy, Robinson,
and Company, of Salford, in the County of Lancaster, Machine Makers,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN MACHINERY FOR SPINNING AND DOUBLING" to bе дs follows:-
My Invention consists, first, in an improved mode of giving motion
to the spindles of self-acting or other mules. Within the carriage is a
longitudinal shaft, on which are fixed any convenient number of grooved
pulleys; each grooved pulley is provided with a band, which is carried
round the wharves of twelve or other convenient number of spindles.

page_text: thereby giving motion to them; by this means the tin drums, rollers, or
gearing are dispensed with.
Another improvement consists in dispensing with the long boss
pulley on the rim band shaft of Robert's self-acting mules, and applying
a clutch box to the putting up wheel. The loose catch box on the rim
band shaft is drawn out of gear during the backing off and putting up
of the carriage, and put into gear when the spinning is being performed.
By this arrangement the driving strap remains at all times on the
driving pulley.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Oldfield in the Great Seal Patent Office
on the 6th June 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
EDWARD. OLDFIELD, of the firm of Messieurs Oddy, Robinson, and
Company, of Salford, in the County of Lancaster, Machine Makers,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of December, in the year
of our Lord One thousand eight hundred and fifty-three, in the seven-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Edward Oldfield, Her special license
that I, the said Edward Oldfield, my executors, administrators, and
assigns, or such others as I, the said Edward Oldfield, 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," upon the condition (amongst
others) that I, the said Edward Oldfield, by an instrument..in writing.
under my hand and seal, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to bo
performed, and cause the same to be filed in the Great Seal Patent

page_text: Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Edward Oldfield, 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, that is to say:-
The nature of my Invention consists in an improved mode of giving
motion to the spindles of self-acting mules and other machines of the
like nature, used in spinning and doubling cotton and other fibrous
substances; and in order that my Invention may be fully understood
and readily carried into effect, I will proceed to describe the 'means
pursued by me, reference being had to the annexed Drawing, and to
the figures and letters marked thereon.
DESCRIPTION OF THE DRAWING.
Figure 1 is a sectional elevation of the carriage of a mule to which
my improvements are applied. Figure 2 is a front elevation of part of
the carriage representing fifteen spindles driven by the same band; and
Figure 3 is a plan of Figure 2. a is the wood work of the mule
carriage; b, the cast iron end frame of the carriage; c, a shaft extending
the whole length of the carriage; and d, d, are double grooved pulleys
fixed on the shaft c, which is driven in the same manner as the tin
ruller sometimes employed for giving motion to the spindles; e is the
band for driving the spindles f, which are marked from 1 to 15 con-
secutively. The band e, after leaving the left hand groove of the pulley
d, is taken round the wharve of the seventh spindle, then it passes in
front of the spindles to the first spindle, then along the back to the
tenth spindle, then in front to the second spindle, and then along the
back to the eleventh spindle, and so on until it goes along the back
from the sixth spindle to the fifteenth spindle; then it is brought in
front to the ninth spindle, from whence it is taken to the right hand
groove of the pulley d, over which it passes, and then, after being taken
round the eighth or centre spindle, it goes back to the left hand groove
of the pulley d, from whence it started. I also propose to drive 16 or
other convenient number of spindles by the same band, and to fix two

page_text: wharves upon one of the centre spindles, in order that the band may
exert the same or nearly the same power on all the spindles; in this
instance the band, after going from the fifteenth to the upper wharve
on the niuth spindle, is taken to the sixteenth spindle, and then to the
lower wharve on the ninth spindle, then it goes to the right band
groove in the pulley d, and from thence to the eighth spindle, as before
described. By this means any convenient number of spindles are driven
by the same band; consequently, a considerable saving is effected in the
length of banding required, and the tin drums or tin rollers or gearing
usually employed are dispensed with; the power required for driving
the spindles is reduced, and a more equal motion is given to the
spindles.
Having thus described the nature of my Invention, and the manner
of performing the same, I wish it to be understood that I do not limit
myself to the details herein set forth, as the same may be varied without
departing from the peculiar character of my Invention; but what I do
claim is, driving any convenient number of spindles by the same band,
to which motion is given by grooved pulleys fixed on a horizontal shaft,
as herein-before shewn and described.
In witness whereof, I, the said Edward Oldfield, have hereunto
set my hand and seal, this Fifth day of June, One thousand
eight hundred and fifty-four.
EDWARD OLDFIELD. (L.B.)
Signed, sealed, & delivered by the
within-named Edward Oldfield, in
the presence of
H. B. BARLOW,
Patent Agent,
Manchester.
