Year: 1869

page_text: LETTERS PATENT to William Helliwell, James Helliwell, Mitchell
Helliwell, and Thompson Helliwell, all of Pudsey Mill, near
Todmorden, in the County of York, Bobbin Manufacturers, for
the Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF BOBBINS USED
MAGUINDO BAD SIIS DOURING AND THING"
PROVISIONAL SPECIFICATION left by the said William Helliwell,.
James Helliwell, Mitchell Helliwell, and Thompson Helliwell, at
the Office of the Commissioners of Patents, with their Petition,
on the 30th December 1869.
We, WILLIAM HELLIWELL, JAMES HELLIWELL, MITCHELL HELLIWELL,
and THOMPSON HELLIWELL, all of Pudsey Mill, near Todmorden, in the
County of York, Bobbin Manufacturers, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF BOBBINS
USED IN MACHINES FOR SPINNING, DOUBLING, AND TWISTING," to be as
follows:-
The nature of our Invention consists in making the bushes for bobbins
of buffalo, bison, or other suitable hides or skins, or of horn or other
similar substance.

page_text: In making these bushes we punch, roll, or mould annular rings
out of the hide or other substance and glue these rings or bushes into
the ends of the bobbin; these bushes are afterwards bored or rimered out
to make them fit accurately on the spindles. These bushes are more
durable than those made of hard wood, and require no oiling after they
have once been saturated in oil.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Helliwell, James Helliwell, Mitchell
Helliwell, and Thompson Helliwell in the Great Seal Patent Office
on the 29th June 1870.
.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
HELLIWELL, JAMES HELLIWELL, MITCHELL HELLIWELL, and THOMPSON
HELLIWELL, all of Pudsey Mill, near Todmorden, in the County of York,
Bobbin Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of December, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said William Helliwell, James Helliwell, Mitchel
Helliwell, and Thompson Helliwell, Her special licence that we, the
said William Helliwell, James Helliwell, Mitchell Helliwell, and Thomp-
son Helliwell, our executors, administrators, and assigns, or such others
as we, the said William Helliwell, James Helliwell, Mitchell Helliwell,
and Thompson Helliwell, 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 THE CONSTRUCTION OF BOBBINS USED IN
MACHINES FOR SPINNING, DOUBLING, AND TWISTING," upon the condition
(amongst others) that we, the said William Helliwell, James Helliwell,
Mitchell Helliwell, and Thompson Helliwell, our executors or adminis-
trators, by an instrument in writing under our, or their, or one of our
or their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be

page_text: 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 William Helliwell, James
Helliwell, Mitchell Helliwell, and Thompson Helliwell, 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 (that is to say) :-
The nature of our Invention consists in making the bushes for bobbins
of buffalo, bison, or other suitable hides or skins, or of horn or other
similar substance.
In making these bushes we cut, punch, roll, or mould annular rings
out of the hide or other substance and glue these rings or bushes into
the ends of the bobbin; these bushes are afterwards bored or rimered out
to make them fit accurately on the spindles. These bushes are more
durable than those made of hard wood, and require no oiling after they
have once been saturated with oil,
And in order that our Invention may be fully understood and readily
carried into operation, we will proceed to describe the accompanying
Drawing which represents the section of a bobbin suitable for an ordinary
throstle spinning frame constructed according to our improvements; we
wish however to observe here that our improvements are also applicable
to bobbins for other machines used in spinning, doubling, and twisting
cotton and other fibrous substances.
The barrel a is made of wood or other material in the ordinary manner
and it is recessed into the flanges b and c; the bushes & and e are
made by preference of buffalo hide, but other hide or skins may be
used, or the bushes may be made of horn or other suitable animal
substance.
In making the bushes d and e we employ a machine similar to the
machines pow in use for making bushes of box wood with a crown
drill, the internal diameter of which corresponds with the outer diameter
of the bush, and an ordinary drill rather smaller than the spindle on
which the bobbin has to work. The bushes so made or made in any other
manner are then glued into the recesses in the ends of the bobbin, the
bush & fitting against a shoulder in the flange b, by which arrangement
the bush is not liable to be displaced when the bobbin is put on its

page_text: spindle. When the bobbins are so far completed the holes in the
bushes are rimered out to fit the spindle. These improved bobbins are
more durable than those that are bushed with hard wood, and a great
economy in oil is effected, as the bobbins with the bushes so made of hide
or horn after being saturated in oil in the usual manner require no oiling
when at work.
Having thus stated the nature of our Invention and described a con-
venient mode of performing the same, we wish it to be understood that
we do not limit ourselves to the mode of making the bushes, as that may
be considerably varied; but what we do claim as our improvements in
the construction of bobbins is, the application and use of bushes made
made of buffalo, bison, or other suitable hides and skins, and of horn or
other suitable animal substance.
In witness whercof, we, the said William Helliwell, James Helliwell,
Mitchell Helliwell, and Thompson Helliwell, have hereto set our
hands and seals, this Twenty-seventh day of June One thousand
eight hundred and seventy.
