IMPROVEMENTS IN MACHINERY FOR PREPARING AND SPINNING COTTON AND OTHER FIBRES
Year: 1872

page_text: LETTERS PATENT to John Bullough, Machinist, and James Leachman,
Moulder, both of Accrington, in the County of Lancaster, for the
Invention of "IMPROVEMENTS IN MACHINERY FOR PREPARING AND SPINNING
COTTON AND OTHER FIBRES."
PROVISIONAL SPECIFICATION left by the said John Bullough and
James Leachman at the Office of the Commissioners of Patents,
with their Petition, on the 12th December 1872.
We, JOHN BULLOUGH, Machinist, and JAMES LEACHMAN, Moulder,
both of Accrington, in the County of Lancaster, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR PRE-
PARING AND SPINNING COTTON AND OTHER FIBRES," to be as follows:―
•

page_text: Secondly. An improvement in the spindles employed on such frames,
whereby more space is obtained for the reception of oil, causing the
spindles to require lubricating less frequently, and more complete and
regular lubrication of the foot of the spindle and facility for cleansing is
ensured, and less oil is required.
Thirdly. A more economical and secure construction of foot steps for
such spindles.

We construct the "collars "
as follows:-Below the flange of the
collar is a short cylindrical length or tube, the end of which is slightly
rounded off. This portion is received in a hole bored or formed partly 1
through a lug cast to the spindle rail. The bottom of this hole is
slightly concave, to fit the rounded or convex foot or end of the collar,
and the hole in which the said foot or end rests is bored in continuation
(but of less diameter) completely through the said lug. The flange of
the collar has bored through it and tappet or screwed three or more ]
holes, through which and into corresponding holes formed in the lug set
screws are introduced, which secure the collar to the lug, and perfect
perpendicular of the said collar is ensured by adjusting the screws as
required, that is, any irregularity or inequality may at once be corrected
by means of the said screws. Or in lieu of the adjusting set screws we ?
cast or secure to the spindle rail a bearing, on the upper surface of which
are a number of small heads or beads. On these a lug cast to the collar
rests. A bolt and nut and a lock pin are employed for the purpose of
securing the lug upon these heads or beads and to the bearing of the
spindle rail before referred to. The regulating the collars perpendicular
is effected by filing away a portion of one or more of the said heads or
beads, so as to bring the collar to the position required.
The second part of this our Invention relates to the spindles of such
machinery, and consists in forming a recess or chamber, in which oil for
lubricating the foot step of the spindle is contained. This recess or
chamber is formed by “turning down" or reducing the diameter of a
portion of the spindle near to its foot, and which chambered portion is
within the foot step, so that on oil or lubricating matter being intro-
duced to the foot step, the spindle's foot on being placed therein will
displace the lubricant from the bottom of the foot step and force it
upwards, whereon it enters the chamber or space formed as described
between the turned down portion of the spindle and the interior of the

page_text: foot step. Spindles so formed are much more readily cleaned than the
foot steps wherein grooves are cut for the purpose of containing oil.
Thirdly. We cast to the foot steps a lug. The latter is, by means of a
bolt and nut, secured to the bottom rail, thereby dispensing with the old
method of boring the spindle rail.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Bullough and James Leachman in the Great.
Seal Patent Office on the 12th June 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
BULLUOGH, Machinist, and JAMES LEACHMAN, Moulder, both of Accring-
ton, in the County of Lancaster, send greeting.
WHEREAS 'Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of December, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said John Bullough and James Leachman, Her
special licence that we, the said John Bullough and James Leachman,
our executors, administrators, and assigns, or such others as we, the said
John Bullough and James Leachman, 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 "IMPROVEMENTS IN MACHINERY FOR PREPARING
AND SPINNING COTTON AND OTHER FIBRES," upon the condition (amongst
others) that we, the said John Bullough and James Leachman, our
executors or administrators, by an instrument in writing under our, 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 we, the said John Bullough and James
Leachman, do hereby declare the nature of our said Invention, and in

page_text: and ascertamed my
Sheet of Drawings, that is to say :-
This Invention relates,―
Firstly. To improved means of and apparatus for adjusting and
securing to a true perpendicular the "collars" employed in preparing
cotton and other fibres on slubbing, intermediate, and roving frames.
Secondly. An improvement in the spindles employed on such frames,
whereby more space is obtained for the reception of oil, causing the
spindles to require lubricating less frequently, and more complete and
regular lubrication of the foot of the spindle and facility for cleansing is
ensured, and less oil is required.
Thirdly. A more economical and secure construction of foot steps for
such spindles.
We construct the "collars " as follows:-Below the flange of the
"collar" is a short cylindrical length or tube, the end of which is slightly
rounded off. This portion is received in a hole bored or formed partly
through a lug cast to the spindle rail. The bottom of this hole is slightly
concave, to fit the rounded or convex foot or end of the collar, and the
hole in which the said foot or end rests is bored in continuation (but of
less diameter) completely through the said lug. The flange of the collar
has bored through it and tapped or screwed three or more holes, through
which and into corresponding holes formed in the lug set screws are
introduced, which secure the collar to the lug, and perfect perpendicular
of the said collar is ensured by adjusting the screws as required, that is,
any inequality or irregularity may at once be corrected by means of the
said screws. Or in lieu of the adjusting set screws we cast or secure to
the spindle rail a bearing, on the upper surface of which are a number of
small heads or beads. On these a lug cast to the collar rests. A bolt
and nut and a lock pin are employed for the purpose of securing the lug
upon these heads or beads and to the bearing of the spindle rail before
referred to. The regulating the collars perpendicular is effected by filing
away a portion of one or more of the said heads or beads, so as to bring
the collar to the position required.
The second part of this our Invention relates to the spindles of such

page_text: lubricating the foot steps of the spindles is contained. This recess or
chamber is formed by "turning down" or reducing the diameter of a
portion of the spindle near to its foot, and which chambered portion is
within the foot step, so that on oil or lubricating matter being intro-
duced to the foot step, the spindle's foot on being placed therein will
displace the lubricant from the bottom of the foot step and force it
upwards, whereon it enters the chamber or space formed as described
between the turned down portion of the spindle and the interior of the
foot step. Spindles so formed are much more readily cleaned than the
foot steps wherein grooves are cut for the purpose of containing oil.
Thirdly. We cast to the foot steps a lug. The latter is by means of a
bolt and nut secured to the bottom rail, thereby dispensing with the old
method of boring the spindle rail.
Such being the nature of our said Invention we will now proceed to
explain the same by the aid of the accompanying Sheet of Drawings.
At Fig. 1, A is the collar, the lower portion B of which is slightly
rounded off, as shown. The portion B enters the hole formed in the
lug C, cast to or forming a part of the spindle rail. The flange E of the
collar is bored, and corresponding holes in the lug C are tapped or
screwed; the set screws D in these holes are for the purpose of securing
the true perpendicular of the collar, as well as to hold it securely on the
lug. Fig. 2 is a plan view of Fig. 1.
•
In some cases the spindle rail G is cast with a semicircular recep-
tacle G³ for the foot of the collar A, as shewn at one side of Fig. 4, so as
to dispense with boring, the other portion to complete the circle being
cast to the lug C, as shewn at Fig. 3.
Figs. 4 and 5 shew sectional elevation and plan of the bearing F cast
to the spindle rail G. On the upper surface of the bearing are a
number of projections H, H, H, on which the lug O rests. J is a lock pin.
The projections H, H, H, may be filed down as required when adjusting
the perpendicular of the collar, and the lock pin J prevents the collar
turning should the bolt K become loose. L is the spindle, which is
"turned down " or reduced in diameter at M, forming, when the spindle
is within its foot step N (as shewn), a chamber in which oil for lubri-
cating the foot of the spindle lodges.
At Fig. 6 P is a lug cast to the foot step N, which lug is. by bolt R
