IMPROVE- MENTS IN THE CONSTRUCTION OF SHUTTLE TONGUES
Year: 1866

page_text: LETTERS PATENT to Thomas Ivers, of Farnworth, near Bolton, in the
County of Lancaster, Manager, and Jesse Haddock, of Ratcliffe, near
the City of Manchester, Shuttle Maker, for the Invention of "IMPROVE-
MENTS IN THE CONSTRUCTION OF SHUTTLE TONGUES."
Sealed the 5th January 1867, and dated the 9th July 1866.
PROVISIONAL SPECIFICATION left by the said Thomas Ivers and Jesse
Haddock at the Office of the Commissioners of Patents, with their
Petition, on the 9th July 1866.
We, THOMAS IVERS, of Farnworth, near Bolton, in the County of Lancaster,
Manager, and JESSE HADDOCK, of Ratcliffe, near the City of Manchester,
Shuttle Maker, do hereby declare the nature of the said Invention for "Im-
PROVEMENTS IN THE CONSTRUCTION OF SHUTTLE TONGUES," to be as follows:-
In shuttle tongues of the usual construction a considerable amount of
weft is wasted owing to the spring not holding the cop uniformly on the
shuttle tongue or skewer. Now our Invention consists in so connecting the
spring to the tongue or skewer that an uniform pressure is obtained throughout
the entire length of the cop. In performing our Invention instead of fitting
the end of the spring into a horizontal hole in the head or tumbler of the tongue,
which hole is in a line with the skewer, we fit it into a diagonal hole in

page_text: the top of the head or tumbler, so that when the cop is on the action of the
spring is distributed evenly on the inside of the cop instead of in the centre
only as heretofore.
Another mode of construction consists in the application of an additional
spring acting on the end of the present spring by which the cop is held on the 5
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Ivers and Jesse Haddock in the Great Seal
Patent Office on the 8th January 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
IVERS, of Farnworth, near Bolton, in the County of Lancaster, Manager, and
JESSE HADDOCK, of Ratcliffe, near the City of Manchester, Shuttle Maker,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of July, in the year of our
Lord One thousand eight hundred and sixty-six, in the thirtieth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Thomas Ivers and Jesse Haddock, Her special license that
we, the said Thomas Ivers and Jesse Haddock, our executors, adminis-
trators, and assigns, or such others as we, the said Thomas Ivers and
Jesse Haddock, our executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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 "IMPROVE-
MENTS IN THE CONSTRUCTION OF SHUTTLE TONGUES," upon the condition (amongst
others) that we, the said Thomas Ivers and Jesse Haddock, our executors or
administrators, by an instrument in writing under our, or their, or one of our
or their hands and seals, should particularly describe aud ascertain the nature
of the said Invention, and in what manner the same was to be perfornied,
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.

page_text: NOW KNOW YE, that we, the said Thomas Ivers and Jesse Haddock,
do hereby declare the nature of our 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):
:-
In shuttle tongues of the usual construction a considerable amount of
weft is wasted owing to the spring not holding the cop uniformly on the
shuttle tongue or skewer. Now our Invention consists in so connecting the
spring to the tongue or skewer that an uniform pressure is obtained throughout
the entire length of the cop. In performing our Invention instead of fitting the
end of the spring into a horizontal hole in the head or tumbler of the tongue,
which hole is in a line with the skewer, we fit it into a diagonal hole in the top
of the head or tumbler, so that when the cop is on the action of the spring
is distributed evenly on the inside of the cop instead of in the centre only as
heretofore.
Another mode of construction consists in the application of an additional
spring acting on the end of the present spring by which the cop is held on the
tongue.
Our Invention is particularly beneficial when applied to cops that are
wound on tubes, but it may be used when such tubes are not employed.
And in order that our Invention may be fully understood and readily
carried into operation, we will proceed to describe the accompanying Sheet of
Drawings, reference being had to the figures and letters marked thereon.
Figure 1 is a section of a shuttle to which our improved shuttle tongue is
applied; Figure 2 is a plan of the same.
a is the shuttle tongue or skewer; b, the swell or spring piece which acts
on the interior of the cop or bobbin; c is the head or tumbler forming part
of the tongue, and d the pin on which it turns ; e is the usual spring acting
on the tumbler to hold it in position when up to put on the cop or bobbin and
when in the shuttle for weaving; there is a slot in the top of the tumbler,
and a diagonal hole slanting from it to admit the bent end of the spring b,
and this diagonal hole is made at such an angle that the spring b will yield
when the cop or bobbin is forced on the tongue a, and that its pressure will be
distributed uniformly on the interior of the cop when on.
Figure 3 represents a modification of our Invention; in this view the end
of the spring b fits in a hole in the top of the tumbler and is acted upon by
the small spiral or other spring f which is contained in a recess in the
tumbler c; this spring f forces up the end of the spring b, and securely holds
the bottom of the cop when weaving.

Figures 4 and 5 represent another modification of our Invention, in these
views the bent end of the spring 6 passes through the tumbler c, and when
the tongue is up, as shewn in Figure 4, the end of the spring 6 is at liberty
to pass through and beyond the tumbler c, thereby facilitating the putting
on of the cop, but when the tongue is lowered into the shuttle, as shewn in
Figure 5, the end of the spring 6 is acted upon by the usual spring e, and
the spring b is thus made to act with the required force on the interior of
the bottom of the cop. In all the shuttle tongues above described the end of
the spring 6 is brought up to the top of the tumbler, consequently when the
cop is on the skewer the elasticity of the spring causes the bottom of the cop
to be securely held.
Having thus stated the nature of our Invention, and described the manner
of performing the same, we declare that we claim the improved modes of
constructing shuttle tongues as described and shewn in the Drawing, and for
causing the swell or spring to act on the interior of the bottom of the cop or
bobbin when the tongue or skewer is within the shuttle.
In witness whereof, we, the said Thomas Ivers and Jesse Haddock,
have hereunto set our hands and seals, the Fifth day of January, One
thousand eight hundred and sixty-seven.
