IMPROVEMENTS IN SHUTTLE TONGUES
Year: 1866

page_text: LETTERS PATENT to Samuel Nelson, of the City of Manchester, in the
County of Lancaster, for the Invention of "IMPROVEMENTS IN SHUTTLE
TONGUES."
Sealed the 14th August 1866, and dated the 17th February 1866.
PROVISIONAL SPECIFICATION left by the said Samuel Nelson at the
Office of the Commissioners of Patents, with his Petition, on the
17th February 1866.
I, SAMUEL NELSON, of the City of Manchester, in the County of Lancaster,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
SHUTTLE TONGUES," to be as follows:-
Instead of brazing, rivetting, or otherwise permanently fixing the point of
each spring to the point of each tongue as at present adopted, I make those
parts separate and distinct from each other, and hold the point of the spring
to the tongue by entering it into a hole or indentation at or near the point of
the said tongue. The other end of the spring passes through a hole in the
sbank or tumbler, and is placed in contact with a tumbler lever or move-
ment, which allows the spring to be close to the tongue when the tongue is
turned out of the shuttle, but swells or curves the spring when the tongue is
turned into the shuttle, and at the same time leaves that end of the spring

page_text: free when the tumbler lever is turned back. My improved system of keeping
the point of the spring and tongue separate from each other avoids the
expense of fastening them together, prevents the softening of the spring, and
enables the spring to be removed for repair, or another supplied in its place
with facility and dispatch without taking the tongue out of the shuttle.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samuel Nelson in the Great Seal Patent Office on the
16th August 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
NELSON, of the City of Manchester, in the County of Lancaster, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of February, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Samuel Nelson, Her special license that I, the said Samuel
Nelson, my executors, administrators, and assigns, or such others as I, the
said Samuel Nelson, 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
SHUTTLE TONGUES," upon the condition (amongst others) that I, the said Samuel
Nelson, 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 Samuel Nelson, 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 (that is to say):
Instead of brazing, rivetting, or otherwise permanently fixing the point of
each spring to the point of each tongue as at present adopted, I make those
parts separate and distinct from each other, and hold the point of the spring

page_text: to the tongue by entering it into a hole or indentation at or near the point.
of the said tongue, which improved system of keeping the point of the spring;
and tongue separate from each other avoids the expence of fastening them
together, prevents the softening of the spring, and enables the spring to be,
removed for repair or another supplied in its place with facility and dispatch
without removing the tongue from the shuttle.
The manner in which this Invention is to be performed will be clearly,
understood by referring to the figures and letters on the accompanying Sheet.
of Drawings, in which are represented various descriptions of shuttle tongues
constructed according to my improvements..
:
:
Figs. 1 and 2 are longitudinal sections of an ordinary shuttle provided with
my improved shuttle tongue in connection with a tumbler lever for enabling
the spring to be swelled and contracted, the shuttle tongue being, shewn iny
the position for placing or removing the cop in Fig. 1, and in the position-for-
weaving in Fig. 2; Figs. 3 and 4 are side views, and Figs. 5 and 6 top.
views of the spring and tongue detached from the shuttle.
a represents the tongue; b, the spring; c, the shank or tumbler'; and d the
tumbler lever. At or near the point of the tongue there is a hole or indenta-
tion 6, and in the shank or tumbler c. there is a groove or recess f.. The
point g of the spring is entered into the hole or indentation e, and the other or
back end of the spring is entered into the recess.f and placed in contact with
the tumbler lever d which allows the spring 6 to be close to the tongue when
the tongue is turned up out of the shuttle, as in Fig. 1, and causes the spring
to swell or curve upwards when the tongue is turned into the shuttle, as shewn
in Fig. 2, and when the spring has to be loosened or removed, the tongue is
turned out of the shuttle and the tumbler lever turned back. Fig. 7 is a side
view, Fig. 8 a longitudinal section, Fig. 9 a top view, and Fig. 10 a
transverse section of a round tongue provided with my improved separate
spring. The only difference between this tongue and that before described is
that it is formed of a round shape and has a long groove h for the spring b to
bed in when the tongue is turned up out of the shuttle for placing or removing
the cop.
Figs. 11, 12, and 13 are longitudinal sections of some of the various
arrangements of the springs of shuttle tongues to which my improvements can
be applied. At or near the points of the tongues there are holes or inden-
tations into which the points of the springs are entered, but the back ends of
the springs are connected to the shank or tumbler in different ways. In
Fig. 11 the back end of the spring b is bent at right angles and passed
through a hole in the sbauk or tumbler c, and when the tongue is in the

page_text: shuttle the bottom of the end i is in contact with the ordinary spring 1, and
the spring is swelled or expanded for tightening the cop, but when the
tongue is turned up out of the shuttle the end i is at liberty, and the spring b
can be pressed close to the tongue for enabling the cop to be placed on or
removed from the tongue. In Fig. 12 the back end of the spring 6 is placed-
in a small spiral spring m embedded in the shank or tumbler c, which spring
contracts by pressure for enabling the cop to be placed or removed, but
expands and swells out the spring 6 when the pressure is taken off. In
Fig. 13 the back end of the spring 6 is entered into a hole in the shank c,
and the spring is in contact with the spring n fixed to the tongue, the action
of which produces the same effect as the spiral spring m, Fig. 12.
Having now described the nature and particulars of my said Invention, and
the manner in which the same is to be performed, I desire it to be understood
that I claim in shuttle tongues the system of making the point of each spring
and the point of the tongue separate and distinct from each other and holding
the point of the spring to the tongue by entering it into a hole or indentation
at or near the point of the tongue, as such improvements are herein described
and illustrated in the accompanying Sheet of Drawings.
In witness whereof, I, the said Samuel Nelson, have hereunto set my
hand and seal, this Fourteenth day of August, in the year of our
Lord One thousand eight hundred and sixty-six.
Signed, sealed, and delivered by the
within-named Samuel Nelson, in
the presence of
E. J. HUGHES,
Patent Agent
Manchester.
