Sealed the 17th June 1856, and dated the 10th March 1856.
PROVISIONAL SPECIFICATION left by the said James Mills at the Office
of the Commissioners of Patents, with his Petition, on the 10th March
1856.
I, JAMES MILLS, of Oldham, in the County of Lancaster, Machinist, do
hereby declare the nature of the said Invention for "AN IMPROVEMENT IN
SPINDLES USED IN CERTAIN MACHINES FOR PREPARING, SPINNING, AND DOUBLING
COTTON AND OTHER FIBROUS SUBSTANCES," to be as follows:-
My Invention consists in making the spindle with a cast-iron bush or
hollow tube, which slides up and down on the spindle, but is prevented from
turning round upon it by a pin, which passes from the inner side of the bush
into a groove formed in the spindle; or two pins and two grooves, one on each
side of the spindle, may be used.

by the said James Mills in the Great Seal Patent Office on the
8th September 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
MILLS, of Oldham, in the County of Lancaster, Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of March, One 'thousand eight hundred
and fifty-six, in the nineteenth year of Her reign, did, for Herself, Her heirs
and successors, give and grant unto me, the said James Mills, my executors,
administrators, and assigns, Her especial licence that I, the said James Mills,
my executors, administrators, and assigns, or such others as I, the said James
Mills, my executors, administrators, or assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the term
of years 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 IMPROVEMENT IN SPINDLES
USED IN CERTAIN MACHINES FOR PREPARING, SPINNING, AND DOUBLING COTTON AND
OTHER FIBROUS SUBSTANCES," upon the condition (amongst others) that I, the
said James Mills, my executors or administrators, should particularly describe
and ascertain the nature of the said Invention, and in what manner the same
was to be performed, by an instrument in writing under my, or their, or one
of their hands and seals, 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 in compliance with the said proviso, I, the said
James Mills, do hereby declare that the nature of my said Invention, and the
manner in which the same is to be performed, are particularly described and
ascertained in and by the following statement and description, referénce being
had to the accompanying Drawings on one Sheet, and in which description
and Drawings the same letters and numbers of reference are used to indicate
the same parts in all the Figures in which they occur.
My Invention consists in applying bushes or hollow tubes of cast-iron-or
other suitable metal to the spindles used in the 'before-mentioned machines
in such manner that the bush will rotate with the spindle, and at the same
time be at liberty to slide up or down on the same, as may be required.

page_text: DESCRIPTION OF THE DRAWINGS,
in which the Figures are represented of the full size of the parts represented
as employed in a slubbing frame. The size of these parts, as is well known,
varies in the other machines of the kinds before mentioned.
Figure 1 is an elevation, and Figure 2 is a vertical section, of part of a
spindle with my improvement; Figure 3 is an elevation of the bush applied
by me; and Figure 4, an elevation of the bush usually employed.
In the spindle A are cut the two grooves a, which must be of sufficient
length to allow the bush C (the pins c from which enter into the grooves a, as
herein-after described,) to be moved up or down the spindle to the required
extent. In the bush C are fixed the pins c, projecting into the grooves a, and
which cause the bush C to rotate with the spindle, but allow it to be moved
up or down to the extent of the grooves a; if preferred, one pin and one
groove only may be adopted. The bush B is fixed in the lifting rail, and is the
bush usually employed, and in which, according to the ordinary construction,
the spindle A would rotate, but according to my improved arrangement the
bush C, interposed between the spindle and the fixed bush B, rotates within the
the latter, whereby the spindle is protected from wearing away so rapidly as it
does in the ordinary construction when rotating within and in contact with the
bush B, the only friction to which it is exposed, as constructed by me, being
that occasioned by the upward and downward motion of the bush C, whilst
the principal friction will be sustained by the bushes B and C, which may,
when necessary, be renewed at a much less expense than is consequent on the
wearing away of the spindle under the ordinary arrangement. By my arrange-
ment a saving of oil is also effected.
In witness whereof, I, the said James Mills, have hereunto set my hand
and seal, this Sixth day of September, in the year of our Lord One
thousand eight hundred and fifty-six.
30 Signed, sealed, and delivered by the said
James Mills, in the presence of
CHARLES ASTON,
Attorney-at-Law, Manchester.
