OR BOBBINS FOR SEWING THREAD." Communicated to him from abroad by

of the Commissioners of Patents on the 8th August 1882.

EDMUND HUNT, of Glasgow, in the County of Lanark, North Britain, Patent
Agent, "IMPROVEMENTS IN SPOOLS OR BOBBINS FOR SEWING THREAD Com-
municated to me from abroad by Ina Craven Davis residing at Mo[u]ut Clair, New
Jersey, United States America.
This Invention comprises two improvements in spools or bobbins for sewing
thread.
One improvement consists in forming on the head or end which is to be
undermost when the spool or bobbin is placed on the holding spindle of a sewing
machine, a boss or concentric projection which is grooved or undercut so as to have
the outer part larger than a part nearer the head. The object of this improvement
is to prevent the thread from winding on the spindle as it is apt to do when
slipping over the head or end of an ordinary spool or bobbin.
With the improved
spool or bobbin the thread catches in the groove of the boss, and has more power
to turn the spool or bobbin than when it gets on the spindle. Grooved bosses may
be formed on both heads or ends.
The object of the second improvement is to allow of the fineness or color or
quality of the thread being ascertained in a better inanner than it can be from the
closely set and compressed coils, and without requiring to pick out the end with a
pin and to unwind a portion of it, and also without leaving a sufficient portion
loose. In carrying out this improvement the usual fastening nick is used, and in
addition a second nick or other suitable fastening device is provided and a portion

page_text: of the thread after being fixed in the first nick is extended so as to lie across or
over a part of the head or end and the extreme end is fixed in the second nick or
device. In this way a portion of the thread is displayed upon the head or end
so that its quality can be easily seen. A boss or projection may be formed on the
end or head of the spool or bobbin and the thread may be led more or less round
it. Or the end of the thread may be led across the bore hole of the spool or bobbin
Bo as to be forced up by the spindle when the spool or bobbin is placed thereon.
The extreme end of the thread may be secured by means of the usual label on the
end of the spool or bobbin or by means of one or more nicks in the end or in a
boss or projection thereon.

EDMUND HUNT, of Glasgow, in the County of Lanark, North Britain, Patent
Agent "IMPROVEMENTS IN SPOOLS OR BOBBINS FOR SEWING THREAD
A com-
munication to me from abroad by Ina Craven Davis residing at Mo[u]nt Clair,
New Jersey, United States America,
The said Invention comprises two improvements in spools or bobbins for sewing
thread.
One improvement consists in forming on the head or end which is to be
undermost when the spool or bobbin is placed on the holding spindle of a sewing
machine, a boss or concentric projection which is grooved or undercut so as to have
the outer part larger than a part nearer the head. The object of this improvement
is to prevent the thread from winding on the spindle as it is apt to do when
slipping over the head or end of an ordinary spool or bobbin. With the improved
spool or bobbin the thread catches in the groove of the boss, and has more power
to turn the spool or bobbin than when it gets on the spindle. Grooved bosses
may be formed on both heads or ends.
The object of the second improvement is to allow of the fineness or color or
quality of the thread being ascertained in a better manner than it can be from the
closely set and compressed coils, and without requiring to pick out the end with a
pin and to unwind a portion of it, and also without leaving a sufficient portion
loose. In carrying out this improvement the usual fastening nick is used, and in
addition a second nick or other suitable fastening device is provided, and a portion
of the thread after being fixed in the first nick is extended so as to lie across or over
a part of the head or end and the extreme end is fixed in the second nick or device.
In this way a portion of the thread is displayed upon the head or end so that its
quality can be easily seen. A boss or projection may be formed on the end or head
of the spool or bobbin and the thread may be led more or less round it. Or the
end of the thread may be led across the bore hole of the spool or bobbin so as to be
forced up by the spindle when the spool or bobbin is placed thereon. The extreme
end of the thread may be secured by means of the usual label on the end of the
spool or bobbin or by means of one or more nicks in the end or in a boss or
projection thereon,
And in order that the said Invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings to
be hereinafter referred to and representing spools or bobbins as made or provided
with the improvements
Figures, 1, and 2, on the accompanying sheet of drawings represent spools or
bobbins as made with modifications of the first improvement, each spool having on
one end a concentric boss or projection which tapers or diminishes in diameter
from a sharp outer edge for the purposes hereinbefore explained.
Figures 3, to 11, on the accompanying sheet of drawings represent spools or
bobbins with various modifications of the second improvement. In figure, 3, the
spool end is made with diametrically opposite nicks and the thread is placed in
both so as to have a portion displayed across the end of the spool. In figure, 4, a
larger portion of the thread is displayed by carrying the part of it between the
two nicks round a slightly projecting boss formed on the end. In figure, 5, instead
of the second nick in the edge of the spool end a nick or groove for the thread is
formed across a boss on the spool end. Figure 6, is similar to figure, 4, but shows

page_text: a large portion of thread wound or laid round the boss on the spool end. In
figure, 7, the thread is placed in a nick in one end then carried round in a groove
in a boss and finally led to a nick in the other end of the spool. Figure, 8, is
similar to figure, 5, but with the groove or grooves in the boss made so that the
thread crosses the bore hole. In figure, 9, a groove or cut for the thread is formed
in the edge of the boss close to the spool end. In figure, 10, the thread instead of
being secured in a second nick is laid across a boss on the spool end and secured
by a label being gummed over it; and in figure, 11 the thread end is secured in a
similar way on a flat spool end made without a boss.
Having thus particularly described the said Invention and the manner of
performing the same I have to state that what I believe to be novel and original
and claim as the Invention secured to me by and in terms of the hereinbefore in
part recited Letters Patent is :-
1. A spool or bobbin having on its head a projecting boss which is smaller than
the head and which tapers from a sharp outer edge inwards towards the head
substantially as and for the purpose herein before described.
2. The providing of spools or bobbins with a second fastening for the thread
such second fastening being arranged in any of the modes herein shown and
described so as to display a portion of the thread on the end of the spool or
bobbin.
In Witness whereof, I, the said Edmund Hunt, have hereunto set my hand
and seal this first day of February in the year of our Lord One thousand
eight hundred and eighty-three.
EDMUND HUNT. (L.S.)
