page_text: LETTERS PATENT to Daniel Hussey, a resident of Nashua, in the State
of New Hampshire, of the United States of America, for an Invention
"HAVING REFERENCE TO BOBBINS AND THE WINDING OF ROVING OR YARN
THEREON.
COMPLETE SPECIFICATION filed by the said Daniel Hussey at the
Office of the Commissioners of. Patents, with his Petition and
Declaration, on the 25th June 1863, pursuant to the 9th Section of the
Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, BE IT
KNOWN, that I, DANIEL HUSSEY, a resident of Nashua, in the State of
New Hampshire, of the United States of America, have made a new and
useful Invention "HAVING REFERENCE TO BOBBINS AND THE WINDING OF ROVING
OR YARN THEREON," and I do hereby declare the nature of my said Inven-
tion, and the manner in which the same is to be performed, or in other
words its construction and mode of operation to be fully described in the
following Specification, and represented in the accompanying Drawings.
The nature of my Invention consists in an.improved double-coned bobbin or
spool. Also, in a peculiar mode of winding or laying the roving or yarn thereon,
such consisting in increasing the width of each successive layer of the roving
or yarn until the cones and the body or part uniting them shall be completely.

page_text: covered, and subsequently diminishing the width of each succeeding layer of
such yarn or roving until the requisite amount thereof shall have been wound
on the bobbin.
I would observe that ordinary spools for spooling roving are made cylindrical
from end to end, and are provided with a recess and cross notches at
each end.
Figure 1 denotes a side view, Figure 2 an end view, and Figure 3 a
longitudinal section of a bobbin or spool so made; Figure 4 is a side view,
Figure 5 is an end view, and Figure 6 is a longitudinal section of a spool
constructed in accordance with my Invention. The common cylindrical spool
or bobbin shown in Figures 1, 2, and 3 is constantly liable to be broken at
one or both of its ends, where it is very weak, and, furthermore, the pin
notches at the ends are apt to catch and entangle roving or yarn. In my
improved roving spool or hobbin each of the end parts A, A, is of greater
diameter than the body B, and consists of a conic frustrum united thereto and
arranged therewith, as shown in Figures 4 and 6.. A cylindrical chamber a.
is made axially and concentrically in each part A, and is furnished at its open
end with four radial pin. notches b,.b, b, b, which are formed within the base,
but do not open out of its edge or circumference, as do the corresponding
notches b', 6, 6, 6', of the ordinary cylindrical spool represented in Figures 1,,
2, and 3. The said arrangement of the notches b, b, b, b, which are to receive
a pin or stud of the spindle, is highly favorable to the durability of the spool or-
bobbin. Figure 7 denotes a section of a cylindrical spool and the roving as
wound thereon; Figure 8 represents one of my improved spools of the same
length and diameter of body, and with roving laid on it in accordance with my
Invention, the cylindrical parts of the mass of roving on each spool being
equal in diameter. With my improved method of laying the roving on the
bobbin a great gain in the amount wound thereon results in comparison with
the mode of winding on the cylindrical bobbin or spool. This will be apparent
from Figure 9. If we suppose A in. the said Figure 9 to exhibit a cylindrical
bobbin, and f, c, the slope of the conical frustum of roving to be laid at each
end of each bobbin, we shall find. the said conical frustum to be generated by,
the triangle.f, b, c, revolved about the cylinder A.
.
Again, suppose we desire the slope of the conical frustum at each. end of the
improved double-coned bobbin. to be the same as that of the cylindrical bobbin.
In this case the conical head or frustum at the end of the bobbin A would be
generated by the trapezoid a, d, i, g, revolved about the cylinder A. The line a, e,
would be parallel to the line f, e, and instead of the triangular section f, b, c,
resting on the base b, c, we should have the figure a, d, b, c, e. As the two

page_text: triangles f, b, c, and a, b, c, have the same base and altitude, they measure the
same area, consequently the figure a, d, b, c, e, will exceed the triangle f, b, c,
by the two triangles a, d, b, and a, c, e, or by the parallelogram a, e, c, h, which,
in a manner, will represent the gain by the employment of the conical head
and the process of winding the yarn or roving in accordance with my Inven-
tion. The gain is greater, because much more yarn or roving would be wound
in the triangular spaces a, k, h, and a, h, c, than can be in those marked f, k, d,
and a, d, b. In the process of winding the layers of roving on the double-
coned spool or bobbin, each successive layer is to be increased in width until
the two cones are covered by the yarn or roving. After which each successive
layer laid on should diminish in width until the cylinder wound on the bobbin
receives a length equal to the distance between the two cones or conical frustra.
composing the two heads.
I claim the improved double-coned bobbin or spool as made with each of
its pin notches, formed and arranged relatively to the outer edge of the head,
substantially as described.
And I also claim my improvement in the manner of laying the roving on a
double-coned bobbin, the same being substantially as described.
In witness whereof I have hereunto set my hand and seal, this 5th day
of June 1863.
