Chester. "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SPINNING AND
DOUBLING COTTON AND OTHER FIBROUS MATERIALS."
"
Our said Invention relates to spinning or doubling frames in which the upper
part of the spindle runs in a long sleeve or bearing secured to the rail and
provided with a loose, separate, and concentrically mounted bobbin carrier as is
well understood. The said bobbin carrier usually consists of a steel tube bored so
as to run loosely upon the aforesaid fixed sleeve or bearing, and turned on the
outside so as to slip easily into the central hole of the bobbin. In removing or
doffing" the bobbin from the said carrier it is necessary to provide means for
preventing the removal of the carrier from the sleeve at the same time. According
to our Invention we obtain this result in the following manner:-We bore the
carrier until within a short distance from the foot to fit loosely upon the sleeve,
and complete the bore for the remaining short distance to the foot to a diameter
slightly less than the bore above, so as to present a slight tapered shoulder. The
foot of the carrier is rendered elastic by the formation of two or more slits or
sawgates. The upper part of the supporting sleeve is turned slightly tapered in
form so as to enter the bobbin carrier easily at the top, but to be slightly more
than the bore of the carrier at the lower part of the bearing. At this enlarged
part the sleeve is partly reduced or checked so as to present a shoulder similar to
that within the carrier. When the carrier is slipped upon the sleeve a slight
amount of force will required to be exerted to cause the reduced slit part of the
Dins G71

page_text: carrier to pass the enlarged portion of the sleeve bearing. Immediately however
upon passing this enlarged portion the resilience of the split portion of the carrier
causes it to contract and bring its internal shoulder opposite to the shoulder or
check on the sleeve bearing. The carrier is thus prevented from being removed
along with the bobbin, as the force necessary to "doff" the bobbin from the carrier
is not sufficient to overcome the elastic adhesion between the carrier and the sleeve.
When desired however the carrier may be removed from the sleeve by employing
sufficient force to overcome the resistance of the elastic carrier foot. Our Invention
further consists in forming at the lower part of the fixed sleeve a recess or well
which acts as a step for the carrier to run in, and also serves to catch and retain
any oil which may come from the bearing or bearings above. The oil is thus
prevented from reaching the rail or from flowing past the upper bearings to the
lower part of the spindle. The prolongation of the carrier running in this step
is preferably utilized as the spring clip portion of the carrier herein before
referred to,

ISAAC BUCKLEY and EDWIN CROSSLEY, both of Dukinfield, in the County of
Chester. "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SPINNING AND
DOUBLING COTTON AND OTHER FIBROUS MATERIALS."
Our said Invention relates to spinning or doubling frames in which the upper
part of the spindle runs in a long bolster or bearing secured to the rail and
provided with a loose sleeve or bobbin-carrier as is well understood. The said
bobbin-carrier usually consists of a steel tube bored so as to run loosely upon the
aforesaid bolster or bearing, and turned on the outside to suitably fit the hole in
the bobbin. The object of our Invention is to provide means for preventing the
removal of the carrier from the bolster when "doffing." We bore the carrier to
within a short distance from the foot to fit loosely upon the sleeve, and complete
the bore for the remaining short distance to the foot to a diameter slightly less
than the bore above so as to form an internal shoulder. The foot of the carrier is
rendered elastic by the formation of two or more slits or sawgates. The bolster is
formed with a shoulder similar to that within the carrier. When the carrier
is placed upon or removed from the bolster an amount of force will be required to
cause the slit part of the carrier to pass over the larger diameter of the bolster.
The carrier is thus prevented from being removed along with the bobbin, as the
force necessary to "doff" the bobbin from the carrier is not sufficient to overcome
the elastic adhesion between the carrier and the bolster. Our Invention further
consists in forming at the lower part of the bolster a recess or well which acts as a
step for the carrier to run in, and also serves to catch and retain any oil which
may come from the bearing or bearings above.
And in order that our Invention may be fully understood we have attached
hereunto a Sheet of Drawings to which reference will be made in this place. In
the said Drawings Fig. 1 represents a sectional elevation, and Fig. 2 an outside
view of a bolster and carrier or sleeve constructed in accordance with our
Invention; and Fig. 3 is a separate view of the said carrier. In the said Figs. a is
the bolster, and b is the carrier. The bolster is formed for attachment to the rail,
indicated by c, as is usual, and is turned with two collars d and e which loosely fit
the interior of the carrier when it is in its place upon the bolster. The carrier is
formed with a collar b¹ upon which the bobbin and washer rest as is usual, and
with a tubular extension 6 which is slit or cut with saw-gates, one of which is
seen at f in Fig. 3. A slight shoulder is formed within the carrier at the lower
end of the extension 62, as seen at g in Fig. 1, this part of the carrier being bored
a little less in diameter than the remainder of the carrier extending from the
shoulder to the upper end, and also less in diameter than the collar e upon the
bolster. When the bobbin is doffed the tendency of the carrier to leave the bolster
with the bobbin is checked by reason of the shoulder g coming in contact with the
shoulder formed by the lower edge of the collar e, and the carrier is thereby
retained upon the bolster. When it is desirable for any reason to remove the
carrier entirely from the bolster it is only necessary to exert a little more force
than is required when doffing, when the extension 6' will spring by reason of the
saw-gates or slits, whereby the shoulder g will be enabled to pass over the collars
on the bolster. In the same way the exertion of a little force is simply necessary
to "spring" the carrier when replacing it upon the bolster. We do not confine
ourselves to the precise forms of the bolster and carrier so long as the shoulders e
and 7 and the saw-gates or slits are retained with the described object.

page_text: On referring to Fig. 1 it will be seen that the collar a¹ on the bolster is made
deeper than is usual and that a deep annular shaped well is turned or formed in
this collar. This well serves to contain the spring extension 62, and also to retain
any oil which may flow down from the upper bearing, as herein before mentioned.
Such oil is thus prevented from flowing over the edge of the collar a¹ with which
the drag washer usually comes into contact in this description of apparatus. A
spiral groove may also be cut upon the bolster to lift the oil from the well to the
upper bearing or bearings.
Having now fully set forth and indicated the nature of our said Invention, and
the manner in which we carry the same into practical effect, we would have it to
be understood in conclusion that we claim,―
First. The parts of spinning apparatus formed substantially as and for the
purpose set forth and indicated hereinbefore and in and by the accompanying
Drawings.
Secondly. The carrier slit to spring and formed with a shoulder g in connection
with a bolster formed with a shoulder e, substantially as and for the purpose set
forth and indicated.
And, Lastly. The well h, for the purpose or purposes set forth and indicated.
In witness whereof, we, the said Isaac Buckley and Edwin Crossley, have
hereunto set our hands and seals, this Ninth day of March; in the year of
our Lord One thousand eight hundred and eighty-two.
