IMPROVE- MENTS IN BOBBIN HOLDERS
Year: 1865

page_text: LETTERS PATENT to John Goulding, of Worcester, in the State of
Massachusetts, United States of America, for the Invention of "IMPROVE-
MENTS IN BOBBIN HOLDERS."
Sealed the 21st November 1865, and dated the 21st September 1865.
PROVISIONAL SPECIFICATION left by the said John Goulding at the
Office of the Commissioners of Patents, with his Petition, on the 21st
September 1865.
I, JOHN GOULDING, of Worcester, in the State of Massachusetts, United
States of America, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN BOBBIN HOLDERS," to be as follows:-
The said Invention relates to a spring bobbin holder attached to the spindle
in spinning and similar machines, and consists of a series of bow springs
surrounding the said spindle, and beld together at the top and bottom ends,
and hence the spring bobbin holder has the general form of an elongated
spheroid, and upon this the bobbin is easily slidden or removed, the springs
flattening or setting closer to the spindle when the bobbin is slidden over
them afford the friction necessary to rotate the bobbin, and the spring holder
is adapted to bobbins with slightly varying holes. This holder may be made of
separate springs, united by a ring, said ring being driven over the spindle, and
retaining the springs in place, or the springs may be formed, of a piece of sheet

page_text: metal slotted longitudinally, so as to form springing ribs, said ribs each being
curved in the shape of an elliptical spring, said piece of sheet metal is to be
rolled or bent up cylindrically to set over the spindle, and form the spring
bobbin holder as aforesaid.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Goulding in the Great Seal Patent Office on the 16th
March 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
GOULDING, of Worcester, in the State of Massachusetts, United States of
America, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of September, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Goulding, Her special license that I, the said John Goulding,
my executors, administrators, and assigns, or such others as 1, the said John
Goulding, my 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 BOBBIN HOLDERS,'
upon the condition (amongst others), that I, the said John Goulding, by an
instrument in writing under my hand and seal, 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
aaid Letters Patent.
"
NOW KNOW YE, that I, the said John Goulding, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, reference being had to the Drawing hereto annexed, and to the
letters and figures marked thereon (that is to say) :-
Fig. 1 is a vertical central section of a spindle, bobbin holder, and bobbin.
"
""
2 is a bobbin holder shown separately from the spindle; and,
3 shows the way in which a piece of sheet metal is cut out to form the
said bobbin holder.

page_text: Heretofore it has been usual to drive the bobbin upon the spindle, and a
winding of yarn has been resorted to to give the necessary friction when the
bobbins have become loose on the spindles. The operation of placing the
bobbins on or removing them from the spindles is liable to bend and injure
said spindles, and to crack the bobbins, beside occupying more time than
necessary. Elastic holders have been employed in the form of linings to the
holes of the bobbins, but they are costly, and troublesoine to fit, and liable to
injury from grease and oil employed on the spindle. All these objections are
obviated by my Invention, which is simple, cheap, and durable, and can easily
be applied to old or new spindles.
The said Invention relates to a spring bobbin holder attached to the spindle
in spinning and similar machines, and consists of a series of bow springs
surrounding the said spindle, and held together at the top and bottom ends;
and hence said spring bobbin holder has the general form of an elongated
spheroid, and upon this the bobbin is easily slidden or removed, the springs
flattening or setting closer to the spindle. when the bobbin is slidden over
them, afford the friction necessary to rotate the bobbin, and the spring holder
is adapted to bobbins with slightly varying boles. This holder may be made
of separate springs, united by a ring, said ring being driven over the spindle,
and retaining the springs in place, or the springs may be formed of a piece of
sheet metal slotted longitudinally, so as to form springing ribs, said ribs each
being curved in the shape of an elliptical spring; said piece of sheet metal is
to be rolled or bent up cylindrically to set over the spindle, and form the
spring bobbin holder as aforesaid.
In the Drawing, a represents the spindle with the pulley or whirl b; this
spindle is to be supported in the rails or bearings in any usual or desired
manner; c is the bobbin of the required shape, with a hole in the center;
and d is my spring bobbin holder, secured to the spindle, and upon which the
bobbin is slidden, and said holder retains the bobbin, causing it to revolve
with the spindle, and from which holder the bobbin can be removed with ease
by simply drawing it off, thus avoiding the concussion or strain heretofore
usual in withdrawing the bobbin. The spring holder d is formed of a series
of elliptical springs i, i, standing around the spindle, and parallel, or nearly
so, to the axis of said spindle, and these springs may be formed separately,
and connected to each other by a ring at the bottom, but I prefer that a piece
of sheet metal be formed into springing strips by longitudinal incisions or
mortices cut through the same, as represented in Fig. 3, thereby the top and
bottom ends of the springs will remain connected to each other, and said
piece of sheet metal being bent up into a cylindrical form, and the spring

page_text: strips bent outwards into an elliptical.or curved form will produce the said
bobbin holder, which is slipped over the spindle, and driven down to its place.
A ring may be employed as at e, Fig: 1, to hold the ends of the springs
together, or to ensure a more firm attachment to the spindle when the holder
is driven upon the same, and this ring e also becomes a seat for the bobbin to
rest upon. The number of springs in each bobbin holder may be greater
or less than represented, and only one might be used, but I prefer two or
more.
What I claim and desire to secure by Letters Patent is,―
First, a spring holder formed substantially as specified for retaining the
bobbin on the spindle, as set forth:
Second, in combination with the spring bobbin holder I claim the ring e,
forming a seat for the bobbin, substantially as specified.
In witness whereof, I, the said John Goulding, have hereunto set my
hand and seal, this Twenty-sixth day of February, A.D. One thousand
eight hundred and sixty-six.
