Year: 1875

Lancaster, Machine Maker, and Charles Butterworth, of Sudden,
in the said County, Carding Master, for the Invention of "IMPROVE-
PROVISIONAL SPECIFICATION left by the said John Oliver and
Charles Butterworth at the Office of the Commissioners of Patents,
with their Petition, on the 3rd December 1875.
We, JOHN OLIVER, of Manchester, in the County of Lancaster,
Machine Maker, and OHARLES BUTTERWORTH, of Sudden, in the said
County, Carding Master, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN BOBBINS FOR SLUBBING OR ROVING FRAMES,"
to be as follows:-
Our Invention refers firstly to the bobbins of those machines in
which the spindle passes through a tube or collar, as for instance, in
that arrangement commonly known as Mason's, and consists in an

page_text: adaptation whereby the bobbin may be placed either end upward. For
this purpose we place within the bobbin a loose bush, capable of sliding
therein, and constituting a bearing wherein the spindle may run. When
the bobbin so arranged is adapted for work, and either end upward, the
loose bush is pushed upward, and remains there as a bearing for the
spindle.
The bobbin may be made in any way now practised, with the exception
that the part used for the "braid " must be at both ends, but we prefer
making the said bobbin of thin steel, and forming recesses therein to
gear with the "braid."
Another part of our Invention consists in making the bobbin with a
longitudinal slot, so that it is capable of compression and expansion as
regards its diameter, to facilitate which we propose to form it of thin
sheet metal, steel by preference.
in
The connection for the "braid" may be made as above described, or
other suitable manner.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Oliver and Charles Butterworth in the
Great Seal Patent Office on the 3rd June 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
OLIVER, of Manchester, in the County of Lancaster, Machine Maker,
and CHARLES BUTTERWORTH, of Sudden, in the said County, Carding

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of December, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc--
cessors, give and grant unto us, the said John Oliver and Charles
Butterworth, Her special license that we, the said John Oliver and
Charles Butterworth, our executors, administrators, and assigns, or such
others as we, the said John Oliver and Charles Butterworth, our
executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during

page_text: the term therein expressed, should and lawfully might use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
MENTS IN BOBBINS FOR SLUBBING AND ROVING FRAMES," upon the con-
dition, amongst others, that we, the said John Oliver and Charles
Butterworth, by an instrument in writing under our hands and seals,
or under the hand and seal of one of us, 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 I, the said John Oliver, and of the said
Charles Butterworth, 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 accom-
panying Drawing (that is to say) :-
Our Invention refers firstly to the bobbins of those machines in which
the spindle passes through a tube or collar, as for instance, in that
arrangement commonly known as Mason's, and consists in an adaptation
whereby the bobbin may be placed either end upward. For this purpose
we place within the bobbin a loose bush, capable of sliding therein,
and constituting a bearing wherein the spindle may run. When the
bobbin so arranged is adapted for work and either end turned upward
the loose bush is pushed upward, and remains there for a bearing for
the spindle.
For this part of our Invention the bobbin may be made of any
suitable material, but the notches or other such parts for connection
with the "braid" must be at both ends; we prefer however making the
bobbin of thin steel.
Another part of our Invention consists in making the bobbin with a
longitudinal slit, so that it is capable of compression and expansion as
regards its diameter.
The first part of these improvements is shewn adapted to a spindle at
Figs. 1 and 2, and in the detached views of the bobbin, Figs. 3, 4.
At a is the spindle running in the tube or long collar 6, commonly
known as Mason's arrangement, the usual braid being at c. The

page_text: bobbin is at d formed of thin sheet metal, and provided at each end
with recesses e for engaging with the projections on the braid c. Within
the bobbin d is a loose bush f, which at present we form of wood, but
it may be made of metal, and at 9 are circular indentations formed
around the bobbin; the bush ƒ therefore may slide freely within the
bobbin, but is prevented from passing therefrom by the said indentations g,
or it may be retained therein by bending over the ends of the bobbin,
or by other inwardly projecting parts.
When the bobbin is held upright the bush f will slide downward and
rest upon the bottom indentation g, as seen at f*, but when it is adapted
it comes in contact with the top of the tube or collar 6, which pushes it
upward into the position shewn at Fig. 1, and it there constitutes a
bearing for the spindle a. By this arrangement therefore it does not
matter when fresh bobbins are adapted which end thereof the attendant
has upward, by which means a saving of time is effected, and in the case
of adapting filled bobbins to a creel to be doubled they may be turned
end for end, so as to wind off the same way, which is an advantage
well known to spinners.
The bobbin has been described as of metal, but it may be made of
wood or other suitable material.
Our other improvement is shewn in the detached views of a bobbin,
Figs. 5, 6.
At h is the bobbin formed of thin metal, but parted in its circum-
ference by a slit i extending throughout its length. When the material
is wound upon this bobbin the tension causes it to spring slightly
inward, but as its tendency is to return outward it causes the material
to be wound tightly.
The Drawing shews the bobbin with the bush of our first im-
provement.
In Figs. 1, 2, 3, 4, the slit i is not shewn, but the two parts of our
Invention may be combined if desired.
Having thus described and ascertained the nature of our said Inven-
tion, and the manner in which the same is to be performed, we desire it
to be understood that we claim as secured to us under the above in part
recited Letters Patent and for the purposes above set forth,-
Firstly. The use of the sliding bush ƒ.
-

page_text: Secondly. Forming the bobbin of thin metal with a springing slit as
at i.
In witness whereof, we, the said John Oliver and Charles Butter-
worth, have hereunto set our hands and seals, this Second day
of June, in the year of our Lord One thousand eight hundred
and seventy-six.
