Year: 1865

page_text: LETTERS PATENT to Jehiel Keeler Hoyt, of No. 31, Cheapside, in the
City of London, for the Invention of "IMPROVEMENTS IN BOBBINS OR SPOOLS
USED IN SPINNING AND WINDING YARNS AND THREADS."-A communication
from abroad' by Charles Reynolds, of North Kingston, Rhode Island,
United States of América..
Sealed the 9th March. 1866, and dated the 16th. September 1865..
PROVISIONAL SPECIFICATION left by the said Jehiel Keeler Hoyt at
the Office of the Commissioners of Patents; with his Petition, on the
16th September 1865.
I, JEHIBL KEELER How, of No. 8T, Cheapside, in the City of London, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN BOBBINS
OR SPOOLS USED IN SPINNING AND WINDING YARNS AND THREADS," a communica-
tion, to be as follows:-
During the process of spinning wool and other yarns and threads it is
necessary that the bobbins or spools employed in the process should be held
upon their spindles in such a manner that they will not slip or revolve loosely
thereon, and also that the said bobbins or spools should be so held upon their
spindles as to be easily removed when full without the employment of tools or
instruments for that purpose. It is further necessary that the bobbins or
spools should be easily fixed upon and removed from the spindle of the shuttle,
and that they should be held in a proper position on the said spindle during
the process of weaving.

page_text: My improvements consist in forming a recess or chamber in the base or
lower end of the bobbin, and fitting therein a ring or number of rings of
india-rubber or other like substance, to form an elastic packing, which binds
against the sides of the chamber or recess, and holds the bobbin firmly on the
said spindle when at work, and yet allows of its easy removal therefrom when
required. This packing is conveniently and advantageously formed of sections
of india-rubber tubing of the proper bore and external diameter to adapt it to
the diameter of the spindle and chamber formed in the bobbin: This chamber
may be of a cylindrical, conical, or any other suitable form that will hold the
elastic packing securely when the bobbin is being removed from its spindle,
and will also sufficiently compress the sides of the said packing to make it act
successfully when the bobbin is at work on the said spindle. When the
chamber is conical its diameter must be greatest at the upper part. The
packing from its elastic nature will then form a dovetail joint with the sides of
the chamber and cannot be drawn out therefrom when the bobbin is being
removed from the spindle. I prefer, however, to make the chamber or recess
cylindrical, and of such a length as to admit therein a ring or washer of wood
or other suitable material in addition to the elastic packing. This ring or
washer being glued or otherwise firmly secured in its position in the outer end
of the chamber will keep the packing from being drawn out therefrom. The
chamber is larger in diameter than the bore of the bobbin, the packing there-
fore cannot be displaced and carried up into the said bore when the bobbin is
forced down upon the spindle.
Elastic packing employed in the manner herein set forth is applicable to
any kind of bobbins or spools used in drawing frames or other kinds of
spinning or winding machinery in all cases where it is necessary to prevent
rotation or slipping round on the spindles.
SPECIFICATION in pursuance of the conditions of the Letters Patent, fibed
by the said Jehiel Keeler Hoyt in the Great Seal Patent Office on
the 16th March 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEHIEL
KEELER HOYT, of No. 31, Cheapside, in the City of London, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of September, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth year of Her

page_text: reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Jehiel Keeler Hoyt, Her special licence that I, the said Jehiel
Keeler Hoyt, my executors, administrators, and assigns, or such others as I,
the said Jehiel Keeler Hoyt, 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 BOBBINS OR SPOOLS USED IN SPINNING AND
WINDING YARNS AND THREADS," a communication, upon the condition (amongst
others) that I, the said Jebiel Keeler Hoyt, 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 Inven-
tion, 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 Jehiel Keeler Hoyt, 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 accompanying Sheet of Draw
ings, making a part of this Specification, in which Figure 1 represents a vertical
section of a bobbin, and Figure 2 an end view of the same; Figure 3 repre-
sents a vertical section of a bobbin fixed upon its spindle, and Figure 4 a
vertical section of a bobbin of modified construction. Like letters refer to
corresponding parts in each of the Figures.
During the process of spinning wool and other yarns and threads it is
necessary that the bobbins or spools employed in the said process should be
held upon their spindles in such a manner that they will not slip or revolve
loosely thereon, and also that the said bobbins or spools should be so held upon
their spindles as to be easily removed therefrom when full without the employ-
ment of tools or instruments for that purpose. It is further necessary that
the bobbins or spools should be easily fixed upon and removed from the
spindle of the shuttle, and that they should be held in a proper position on the
said spindle during the process of weaving.
My improvements consist in forming in the lower end or base A of the
bobbin a chamber or recess, and fitting into the said chamber or recess an
elastic packing B, composed of a ring or number of rings of india-rubber or
other similar elastic substance. This packing binds tightly against the interior
surface of the chamber or recess, and its central perforation is of such a

page_text: diameter as to fit tightly on the spindle C. The bobbin is thereby held firmly
on the said spindle while at work, and can yet be easily and quickly removed
from the said spindle when required. The packing B is conveniently and
advantageously formed of short sections of india-rubber tubing or of india-
rubber rings or washers, formed in any convenient manner of the proper bore
and external diameter to fit properly the diameter of the spindle C, and to fill
the interior of the chamber in the base A when inserted therein, or the said
packing may be composed of a washer formed from sheets of rubber. This
chamber may be parallel, conical, or of any other suitable form that will
retain the elastic packing B securely in its place while the bobbin is being
placed upon or removed from its spindle, and that will also sufficiently com-
press the said packing to make it act successfully when the bobbin is at work
upon the said spindle. When the packing chamber is conical, as represented
in Figures 1. and 3, the diameter of the said chamber must be greatest at its
upper part. The packing B must be compressed and forced into the chamber
and will from its elastic nature expand and form a dovetail joint with the
interior surface of the said chamber, and is thereby retained in the chamber
when the bobbin is removed from the spindle. The chamber or recess is,
however, by preference made with its sides parallel, as represented in Fig.
and of such a length as to admit therein a ring or washer D of wood or other
suitable material in addition to the elastic packing B. This ring or washer D
is provided with a central perforation for the spindle C to pass through, and is
glued or otherwise firmly secured in its position in the outer end of the
chamber. This washer retains the packing B in the packing chamber or
recess when the bobbin is being removed from the spindle C. As this pack-
ing chamber is larger in diameter than the bore or perforation through the
tube E of the bobbin there is no danger of displacing the packing B by
pushing it up into the said tube when the bobbin is being forced down upon
the spindle C.
C
Elastic packing constructed and employed in the manner herein set forth is
free from the objections attendant upon the various methods hitherto in use
for preventing the independent rotation of the bobbins upon their spindles,
and from the cheapness and simplicity of the said packing, it is well adapted
to all kinds of spinning and winding machinery, and is applicable in other
cases where bobbins, spools, reels, or other similar articles are employed for
analogous purposes and operated in a similar manner.
Having thus fully described the said improvements, as communicated to me
by my foreign correspondent, and shewn how the same may be conveniently
and advantagely carried into practice, I wish it understood that I do not

page_text: limit myself to the exact details herein set forth and illustrated in the Drawing,
as these may be considerably varied without departing from the nature of my
Invention; but I claim-
1st, constructing a bobbin or spool with a chamber or recess in the
base A for the reception of the packing B, substantially in the manner
described.
2nd, holding a bobbin or spool upon its spindle C by means of the
packing B, for the purpose and substantially in the manner described.
In witness whereof, I, the said Jehiel Keeler Hoyt, have hereunto set my
hand and seal, this Third day of March, in the year of our Lord
One thousand eight hundred and sixty-six.
Witness,
T. E. JULIAN.
