Year: 1883

page_text: LETTERS PATENT to William Bracewell, Christopher George Bracewell and
Alfred Pilkington, all of Barnoldswick in the County of York, for an
Invention of IMPROVEMENTS IN AND RELATING TO SPINNING AND DOUBLING
PROVISIONAL SPECIFICATION left by the said William Bracewell,
Christopher George Bracewell, and Alfred Pilkington at the Office of the
Commissioners of Patents on the 12th February 1883.
IN
WILLIAM BRACEWELL, CHRISTOPHER GEORGE BRACEWELL, and ALFRED
PILKINGTON, all of Barnoldswick in the County of York. IMPROVEMENTS
AND RELATING TO SPINNING AND DOUBLING COTTON OR OTHER FIBROUS
MATERIAL
Our Invention relates more particularly to those frames or machines used in
spinning which are provided with fixed and loose tubes, the former answer as a
bearing for the spindle and on the latter is placed the bobbin. Now our Improve-
ment consists of an adjustable projection or overlap outwardly applied in such
manner as to be readily turned on or off a flange or rim formed on the loose tube
whereby the said tube may be easily removed from or secured steadily in position
on the fixed tube, and to reduce any unnecessary drag or resistance to the loose
tube its upper end may bear against the spindle or against a collar or ring freely
mounted on the top of the fixed tube.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said William Bracewell, Christopher George Bracewell, and Alfred
Pilkington in the Great Seal Patent Office on the 9th August 1883.
WILLIAM BRACEWELL CHRISTOPHER GEORGE BRACEWELL and ALFRED
PILKINGTON all of Barnoldswick in the County of York. IMPROVEMENTS IN
AND RELATING TO SPINNING AND DOUBLING COTTON OR OTHER FIBROUS
MATERIAL
Our invention relates more particularly to those frames or machines used in
spinning which are provided with fixed and loose tubes, the former answer as

page_text: a bearing for the spindle, and on the latter is placed the bobbin. Now our
improvements consist of an adjustable projection or overlap outwardly applied in
such a manner as to be readily turned on or off a flange or rim formed on the loose
tube, whereby the said tube may be easily removed from or secured steadily in
position on the fixed tube, and, to reduce unnecessary drag or resistance to the
loose tube, its upper end may bear against the spindle, or against a collar or ring
freely mounted on the top of the fixed tube In Order that our invention may be
fully understood and readily carried into effect, we will describe the accompanying
sheet of drawings reference being had to the figures and letters marked thereon
Fig 1 is an elevation. Fig 2 a section, and Fig 3 a plan, in which is represented
the adjustable projection or overlap which formes an essential feature of our
invention. Fig 4 represents a solid collar or ring, and Fig 5 the position the
collar or ring assumes when mounted on the fixed tube. Fig 6 is a section, and
Fig 7 a plan in which views the collar or ring is dispensed with, the upper end of
the loose tube bearing bearing against the spindle. In Figs 1 and 2, A is the
spindle, B the rail, to which is secured the fixed tube C, on which revolves the
loose tube D, its upper end bearing against the solid collar or ring-E which is
freely mounted on the top of the fixed tube C, or against the spindle A as seen in
Fig 6 so that the loose tube D may be relieved from unnecessary drag or resistance
which would otherwise impart an irregular amount of tension to the thread being
wound upon the bobbin. In Figs 1, 2 and 3 the adjustable projection or overlap
is represented by the head of the screw nail F a portion of which is removed so
that the loose tube D may be readily released from or steadily secured by the use
of a screw driver, or similar instrument to bring the full part of the head of the
screw nail F immediately over or off the flange or rim of the loose tube D.
Fige 6 and 7 the adjustable projection or overlap is represented by the pin attached
to the spring G forming a kind of latch capable of shooting over the Hange or rim
of the loose tube D, when placed in position, it will be obvious that the pin of the
spring G will require to be relieved before the said tube can be removed
In
Having now particularly described and ascertained the nature of our said
invention and the manner of carrying the same into practical effect, We Claim as
our invention
Firstly the adjustable projection or overlap substantially as described for
the purpose set forth.
Secondly the spindle as a bearing for the upper end of the loose tube as
described and set forth.
Thirdly the solid collar or ring E as described and set forth.
In Witness whereof we the said William Bracewell Christopher George
Bracewell and Alfred Pilkington have hereunto set our hands and seals this
fourth day of August in the year of our Lord One thousand eight hundred and
eighty threa
