Son, Patent Agents, 123, Chancery Lane, London, for the Invention of
"IMPROVEMENTS IN BOBBINS."-A communication from abroad by Frederick
Wolcott Northrop, of New Haven, in the County of New Haven, State
of Connecticut, United States of America, and Ezra Silliman Munson,
of North Haven, in the County of New Haven, State of Connecticut,
United States of America.
Sealed the 25th October 1867, and dated the 29th April 1867.
PROVISIONAL SPECIFICATION left by the said Edward Thomas Hughes
at the Office of the Commissioners of Patents, with his Petition, on the
29th April 1867.
I, EDWARD THOMAS HUGHES, of the Firm of Hughes & Son, Patent
Agents, 123, Chancery Lane, London, do hereby declare the nature of the said.
Invention for "IMPROVEMENTS IN BOBBINS," a communication to
abroad by Frederick Wolcott Northrop, of New Haven, in the County of New
Haven, State of Connecticut, United States of America, and Ezra Silliman
Munson, of North Haven, in the County of New Haven, State of Connecticut,
United States of America, to be as follows:-
This Invention relates to improvements in the construction of bobbins
employed in the manufacture of yarns or fabrics, the object being to overcome

page_text: the well-known objections to the use of common wood bobbins, and consists in
constructing the spindle of each bobbin of a metallic tube, combined with or
connected to a hollow metallic base, and also in forming upon the spindle at
the base one or more inverted conical shoulders or flanges for the purpose of
causing the thread to cling more readily to the spindle upon the start or upon
motion being communicated thereto.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Thomas Hughes in the Great Seal Patent Office on
the 28th October 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
THOMAS HUGHES, of the Firm of Hughes and Son, Patent Agents, 123,
Chancery Lane, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of April, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Edward Thomas Hughes, Her special licence that I, the said Edward Thomas
Hughes, my executors, administrators, and assigns, or such others as I, the
said Edward Thomas Hughes, 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 "Im-
PROVEMENTS IN BOBBINS," a communication to me from abroad by Frederick
Wolcott Northrop, of New Haven, in the County of New Haven, State of
Connecticut, United States of America, and Ezra Silliman Munson, of North
Haven, in the County of New Haven, State of Connecticut, United States
of America, upon the condition (amongst others) that I, the said Edward
Thomas Hughes, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, 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 Edward Thomas Hughes, do bereby
declare the nature of the said Invention, and in what manner the same is to

page_text: be performed, to be particularly described and ascertained in and by the fol-
lowing statement (that is to say) :-
This Invention relates to improvements in the construction of bobbins, the
object being to overcome the well-known objections to the use of common wood
bobbins, and to produce a bobbin more durable and free from the aforesaid
objections, and consists in forming the spindle of a metallic tube combined
with a hollow metallic base, and also in the peculiar formation of the base of the
spindle, whereby the thread upon the start more readily clings to the base so
that it cannot slip up."
And in order that the Invention may be clearly understood, as well as to
enable others to construct the same, I will proceed to a description thereof,
reference being had to the accompanying Sheet of Drawings, on which
Figs. 1, 3, and 5, are side views respectively of a warp, a filling, and a twist
bobbin; Figs. 2, 4, and 6, are respectively vertical central sections of the
same; and Figs. 7, 8, and 9, respectively lower end views.
The metal which I employ is zinc, and form the tubes A in like manner as
for organ tubes, filling the upper end B, as seen in Figs. 2, 4, and 6, and the
upper end is of larger diameter than the lower end as in common bobbins;
the base c is formed of the same metal, only of sufficient thickness to afford
the necessary strength. The base is formed and secured to the tubes, as seen
in the several Drawings; those of the filling and twist, which in the ordinary
wood bobbins are provided with a pin, I form with a recess or recesses a,
leaving solid parts 6 for the same object that the pins are set into the wood
bobbins (see Figs. 8 and 9). The warp bobbin requiring nothing of this
kind the base is left smooth and apparently solid, as seen in Fig. 7. At the
base of the warp and filling spindles I form several shoulders, each shoulder
being the section of an inverted cone, so that the base of each shoulder is of
smaller diameter than at the top. By this arrangement when the thread is
placed at the base and the winding commences, after having passed two or
three times round, the thread is prevented by the inverted cone-shaped
shoulders from slipping up on the spindle, and no difficulty is experienced at
the commencement of the winding as in common wood spindles; neither can
the thread after being wound slip from the bobbin when it is so firmly beld
at the base, and therefore it is not necessary to form the spindle so much
larger at the top than at the bottom as in the common wood bobbin; the
shoulders upon the cone of the twist bobbin are formed in like manner, as
seen in Figs. 5 and 6, and for the same purpose. Constructed in this manner
the shuttles are extremely light, very smooth, and durable, do not absorb the
oil, are very cheap in their construction, cannot be split, a difficulty so

page_text: common with a wood bobbin, and when, if ever, from accident or otherwise,
the spindles become bruised they are easily repaired so as to be as good as
new, therefore, although the cost of these bobbins is a trifle more at first,
they are in the end cheaper by far than the common wooden spindle.
I am aware that metal tubes for bobbins are not new, and therefore do not
claim constructing a bobbin with a metallic tube; but having thus fully
described the Invention, what I do claim as new and useful and desire to
secure by Letters Patent is,
First, the combination of a hollow metal base C with a tubular metal
spindle A, substantially as and for the purpose set forth.
Second, I claim the inverted conical shoulders formed at the base of the
spindle, substantially as and for the purpose set forth.
In witness whereof, I, the said Edward Thomas Hughes, have hereunto
set my hand and seal, this 28th day of October, in the year of our
Lord 1867.
EDWARD THOMAS HUGHES.
