Year: 1858

page_text: LETTERS PATENT to Henry Bayley, of Staleybridge, in the County of Lan-
caster, Cotton Manufacturer, and John Greaves, of the same Place,
Manager, for the Invention of "IMPROVEMENTS APPLICABLE
MACHINES FOR SPINNING AND DOUBLING FIBROUS SUBSTANCES."
Sealed the 30th September 1858, and dated the 9th April 1858.
PROVISIONAL SPECIFICATION left by the said Henry Bayley and John
Greaves at the Office of the Commissioners of Patents, with their Petition,
on the 9th April 1858.
We, HENRY BAYLEY, of Staleybridge, in the County of Lancaster, Cotton
Manufacturer, and JOHN GREAVES, of the same Place, Manager, do hereby
declare the nature of the said Invention for "IMPROVEMENTS APPLICABLE TO
CERTAIN MACHINES FOR SPINNING AND DOUBLING FIBROUS SUBSTANCES," to be as
follows:-
Our Invention relates to spinning and doubling machines, such as mules,
where tubes are employed as foundations for the bottoms of the cops, and
refers to arrangements for facilitating the placing of such tubes on the
spindles, and it consists in a rail or its equivalent passing from end to end of
the machine in front of the spindles and mounted on the "faller" shafts, or on the
framing carrying the spindles, in such manner that it can be moved from a con-
venient position, in which it is out of the way of the operating parts of the
machine when at work, to a position over the points of the spindles. This rail, or
its equivalent, has holes or receptacles formed in it, one for each spindle, in which

page_text: the tubes are placed, one tube in each hole or receptacle, by the attendants at
intervals of time when unoccupied during the formation of the cops, so that
when the cops are "doffed" and a new set is to be formed the rail or its
equivalent is moved into the position over the points of the spindles, in which
position all the tubes will leave the holes or receptacles in the rail or its
equivalent at the same time and drop upon the spindles. Arrangements are
applied to the rail or its equivalent which prevent the tubes from falling out
when the rail or its equivalent is inverted as it approaches the points of the
spindles till the required time. Instead of the rail or its equivalent being in
one connected length from end to end of the machine, it may be divided into
several sections of any convenient length, arranged as before described. By
these means there is a considerable saving of time in "doffing" and starting a
new "set," during which time the machine is stopped and unproductive.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Bayley and John Greaves in the Great Seal Patent
Office on the 8th October 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
BAYLEY, of Stalybridge, in the County of Lancaster, Cotton Manufacturer,
and JOHN GREAVES, of the same Place, Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of April, in the year of our Lord One
thousand eight hundred and fifty-eight, in the twenty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Henry. Bayley and John Greaves, Her especial license that we, the said Henry
Bayley and John Greaves, our executors, administrators, and assigns, or such
others as we, the said Henry Bayley and John Greaves, 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 APPLICABLE TO CERTAIN
MACHINES FOR SPINNING AND DOUBLING FIBROUS SUBSTANCES," upon the condition
(amongst others) that we, the said Henry Bayley and John Greaves, by an
instrument in writing under our 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

page_text: Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that we, the said Henry Bayley and John Greaves, 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 and accompanying Drawings (that is to say):-
Our Invention relates to spinning and doubling machines, such as mules,
where tubes are employed as foundations for the bottoms of the cops, and
refers to arrangements for facilitating the placing of such tubes on the spindles.
Since the filing of our Provisional Specification we have discovered that Letters
Patent had been granted prior to our application for provisional protection,.
for an Invention having the same object as that described in our Provisional
Specification, which said Invention to some extent diminishes the novelty of
our Invention, as stated in our said Provisional Specification; consequently wo
limit and define our Invention to consist in the arrangement and construction
of mechanism for facilitating the placing of cop foundation tubes on the
spindles of mules for spinning and doubling fibrous materials, that is, in
attaching the rails in which the tubes are placed to arins centered on one of the
faller shafts, in such manner that they can be moved from a convenient
position, in which they are out of the way of the operating parts of the
machine when at work, to a position over the points of the spindles; and in an
improved mode or modes of constructing the rails or receptacles for the tubes,
by which they are readily liberated at the time required, and are caused to
pass freely from the rail on to the spindles. The rails for the tubes are made
in lengths equal to the space between the bolsters or supports of the faller
shafts.
The manner of constructing and arranging the rails for the tubes herein-after
more particularly described, we have found after considerable experience to
be the only one which can be adopted that will give entire satisfaction, and
our Invention can be applied in all cases without any change or modification
in the mules, as commonly arranged and constructed, and it enables the
operation of "doffing" to be performed quite as soon, if not sooner, with tubes
than without tubes, thereby removing the principal objection to their
employment.
The accompanying Drawing exhibits several methods of constructing the
rails to contain the tubes, which are to be placed on the spindles, and also
shows the manner in which the rails are attached to the arms which are
centered on one of the faller shafts.
Fig. 1 is a front, Fig. 2 an end, and Fig. 3 a plan view of a rail con-

page_text: structed according to one modification of our Invention (which we prefer to
use), and Figs. 4, 5, and 6, and Figs. 7, 8, and 9, are respectively views cor-
responding to Figs. 1, 2, and 3 of two other modifications. In the modifica-
tions represented by Figs. 1, 2, and 3, and Figs. 4, 5, and 6, a is the rail
having holes in it, at the same distance apart as the spindles; b is an iron
guard secured to the side of the rail upon which the ends of the tubes (f) rest
when they are placed in the holes formed in the rail as shown. This guard
prevents the tubes from sticking in the holes when they should drop upon
the spindles; c is a cover, which, when in the position in which it is shown in
Figs. 1 and 3, and Figs. 4 and 6, prevents the tubes from leaving the holes in
the rail, when it is turned over; these covers are hinged to the rail (a), the
centre of the hinge d being placed at the lowest edge of the rail or that edge-
furthest from the cover (c); e is a spring, one end being secured to the cover (c),
the other passing through a staple (g) fixed in the rail (a); this spring (e)
serves to latch and hold the cover (c) in its two positions, shown in full and
dotted line in Figs. 2, 5, and 8, the position represented by dotted line being.
that in which the tubes may be placed in the holes or allowed to drop out..
The rail represented by Figs. 7, 8, and 9 is formed by parts a, c, d, and e,
corresponding to those to which these letters are applied in the modifications:
represented by Figs. 1, 2, and 3, and Figs. 4, 5, and 6, but the tubes (f) are
carried and kept in their places by pegs or pins fixed in the rail. In this
modification the guard 6 used in the modifications shown by Figs. 1, 2, and 3,
and Figs. 4, 5, and 6, is unnecessary; Fig. 10 shows the manner in which
the rails are applied and used; and Fig. 11 is an edge, and Fig. 12 is a side
view of one of the two levers or arms to which each rail is attached. The
boss part of these arms (h) are constructed so that they can be fixed upon
the faller shaft (i) without disturbing it, one side of the boss (h') being re-
moveable, the part being secured, when the arm is placed on the faller shaft (i).
by a set screw (h). The ends of the arms (h) are bent, and have a slot
formed in them to receive a part k fixed to the rails (a), that forms the
means of adjusting the rails to the spindles. In Fig. 10, is the bolster or
support of the fallers i; m, the faller shaft; h is the arm centered on the out-
side faller i. The rail and arm is shown in full line over the point of the
spindles (n), in which position the tube (f) will fall out of the rail and drop
upon the spindles, when the cover c is released, and the rail and arm are
shown in dotted line in that position, which they occupy during the time the
machine is spinning, and when they are to be filled with tubes. When the
rail is in the correct position to drop the tubes on the spindles, the arms (h),
rest upon or against the faller shaft (m), as shewn. The boss part of the

page_text: arms () are made to come close against the bolsters (b), or the bosses of the
faller "sickles" to prevent end movement in the rails (a).
We have now particularly described the nature of our Invention, and the
mode of carrying the same into effect, and claim as our Invention,―
Firstly, the methods of constructing rails for facilitating the placing of
foundation tubes on the spindles of mule spinning and doubling machines, as
herein-before described.
Secondly, the centering of arms, carrying rails or their equivalents, for faci-
litating the placing of foundation tubes on the spindles of mule spinning and
doubling machines on the faller shafts, as herein-before described.
In witness whereof, we, the said Henry Bayley and John Greaves, have
hereunto set our hands and seals, this Fourth day of October, in the
year of our Lord One thousand eight hundred and fifty-eight.
