IMPROVEMENTS IN SHUTTLES- ⚫ OR SHUTTLE TONGUES
Year: 1855

page_text: LETTERS PATENT to John Barton, of Stockport, in the County of Chester,
Shuttle Manufacturer, for the Invention of "IMPROVEMENTS IN SHUTTLES-
⚫ OR SHUTTLE TONGUES."
Sealed the 17th June 1856, and dated the 24th December 1855.
PROVISIONAL SPECIFICATION left by the said John Barton at the
Office of the Commissioners of Patents, with his Petition, on the 24th
December 1855.
I, JOHN BARTON, of Stockport, in the County of Chester, Shuttle Manu-
facturer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN SHUTTLES OR SHUTTLE TONGUES" to be as follows :-
In the common shuttle the tongue or peg on which the cop or bobbin is
placed is made with a piece extending the length of it, which is generally
soldered at one end to the point of the peg, the other end being free in a hole
formed in the "shank "or "tumbler" part of the peg. The piece so fixed is
bent or made to "swell" from the- peg, to give an elastic action when the cop
or bobbin is placed on the peg, which prevents the cop or bobbin from passing
off from it while the shuttle is weaving. Now this swell spring fixed to the
shuttle peg is objectionable in placing on or taking off the cop from it, causing
great waste in weft by disturbing and entangling the interior of the cop, as
the elastic force of the peg is only required to be exerted when in the position

page_text: for weaving. The object of these improvements is to remedy this objection,
by causing the elastic force on the interior of the cop or bobbin to be exerted
only when the peg is in the position for weaving, which I accomplish by the
following arrangements, in which my Invention consists:- I make the peg with
the attached piece elastic, as in the common shuttle herein-before described,
with these exceptions: the spring or attached piece is made to lic close or
nearly close to the peg "when it is up (or not otherwise acted upon), and not
swell or bow from it as in the common peg; the hole in the tumbler or shank, in
which the end of the attached spring piece is free, is drilled through it to the
back, so that the end of the spring piece can pass through and project a little.
The spring which acts on the square of the "shank" or "tumbler "part of the
peg to keep it in its proper positions, is so arranged that it will act on the end
of the spring piece projecting from the hole drilled in the "shank
"tumbler," when the peg is in the position for weaving, as well as on the
square of the shank or tumbler. By so doing it causes the spring piece
attached to the peg to swell or bend from it, or to swell and exert an elastic
force on the interior of a cop or bobbin when placed.on it; but when the peg
is turned up for removing or placing a cop or bobbin, it is so arranged that the
act of turning up the peg removes the projecting end of the attached spring
piece away from the spring acting on the squares of the shank or tumbler, and
thus allows the attached spring piece to assume by its own elasticity its nearest
position to the peg, and admit of the cop or bobbin being freely removed and
replaced.

:.
NOW KNOW. YE, that I, the said John Barton, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, and the accompanying Drawings (that is to say):-
In the common shuttle the tongue or peg on which the cop or bobbin is
placed is made with a piece extending the length of it, which is generally
soldered at one end to the point of the peg, the other end being free in a hole
formed in the "shank" or "tumbler." part of the peg. The piece so fixed is
bent or made to "swell" from the peg, to give an elastic action when the cop
or bobbin is placed on the peg, which prevents the cop or bobbin from passing
off from it while the shuttle is weaving. Now this swell spring fixed to the
shuttle peg is objectionable in placing on or taking. off the cop from it, causing
great waste in weft by disturbing. and entangling the interior of the cop, as
the elastic force of the peg is only required to be exerted when in the position
for weaving. The object of these improvements is to remedy this objection
by causing the elastic force on the interior of the cop or bobbin to be exerted
only when the peg is in the position for weaving, which I accomplish by the
following arrangements, in which my Invention consists:-I make the peg
with the attached piece. elastic, as in the common shuttle herein-before
described, with these exceptions: the spring or attached piece is made to lie
close or nearly close to the peg when it is up (or not otherwise acted upon),
and not swell or. bow from it as in the common peg; the hole in the tumbler
or shank, in which the end of the attached spring piece is free, is drilled
through it to the back, so that the end of the spring piece can pass through
and project a little. The spring which, acts on the square of the "shank" or
"tumbler "part. of the peg to keep it in its proper positions, is so arranged
that it will act either directly or through a lever on the end of the spring piece
projecting from the hole drilled in the "shank" or "tumbler," when the peg
is in the position for weaving, as well as on the square of the shank or

page_text: tumbler. By so doing it causes the spring piece attached to the peg to swell
or bend from it, or to swell and exert a pressure on the interior of a cop or
bobbin when placed on it; but when the peg is turned up for removing or
placing a cop or bobbin, it is so arranged that the act of turning up the peg
removes the projecting end of the attached spring piece or lever by which it
is acted upon, away from the spring acting on the squares of the shank or
tumbler, and thus allows the attached spring piece to assume by its own
elasticity its nearest position to the peg or tongue, and admit of the cop or
bobbin being 'freely removed and replaced. The annexed Drawing exhibits
four modifications of my Invention, A, B, C, and D; under each letter three
Figures are shown, Fig. 1 being a sectional view of the shuttle, with the
tongue or peg in the position for placing or removing the cop or bobbin;`
Fig. 2; a similar view, with the tongue or peg in the position for weaving; and
Fig. 3, a detached view of the upper side of the shuttle tongue or peg; a is
the shuttle tongue or peg; a¹, the "swell" or spring pièce which acts on the
interior of the cop or bobbin; a³, "shank or tumbler " part
of the tongue or
peg; b, pin or axis upon which the tongue or peġ turns; c, pin against which
the shank rests when in the position for weaving.
The object of my Invention, as before stated, is to cause the spring piece a
to assume the position shewn by Fig. 1, when the peg or tongue is in the
position for placing or removing the cop ór bobbin, and to rise or swell from
the
peg or tongue, and exert a pressure on the interior of the cop or bobbin,
when in the position for weaving, as shewn by Fig. 2; the amount of swell
depending upon the size of the interior of the cop or bobbin. In the modifica-
tion represented by the Figures under the letter A, the spring d, which is
employed to act on the shank (a²) of the shuttle peg, to hold it in the required
positions, is of the helical class, and it acts against the end of the shank when in
the position for weaving, and against the side of it when in the position for
removing or replacing a cop or bobbin. In the other modifications B, C, and
D, the spring (d) employed is that in common use, pressing against the side
of the shank a² when in the position for weaving, and on the end of it when
in the position for removing or replacing the cop or bobbin. In the modi-
fication A, the spiral or helical spring d acts against a loose piece e, and this
pieces presses against the end of the swell piece a', projecting through the hole
drilled through the shank (a²) when in the position for weaving, as will be
readily understood by inspecting the Figures under this letter. In the modi
fication B, the hole in the shank of the peg for the end of the "swell" piece
a¹ is drilled diagonally to the back side; the action of the spring d will be
obvious. In the modifications C and D, a lever is used to transmit the elasti

page_text: force of the spring d to the end of the "swell". piece a'. The fulcrum of
the lever in the modification C, is formed by the axis on which the tongue or
peg turns, and that of the modification D, by a separate pin 6 passing through
the shank. It will be seen (by the Figures 3), that in these modifications the
shank is cut to receive the piece f, forming the lever. It will be readily
understood, when the peg or tongue is in the position for weaving, that the
spring d will act against one side of the lever piece f, and cause the other to
be forced against the projecting end of the "swell" piece a¹. In all the
modifications the shanks of the tongues or pegs (a²) are shewn in section in
the Figures 1 and 2, so as to expose the end of the "swell" piece (a), pass-
ing through the hole in the shank, and the side of the lever pieces f.
I have now particularly described the nature of my Invention, and the
modes of carrying it into effect. I desire it to be understood that I do not
confine myself to the exact details shown in the Drawings, as modifications
may be made without departing from the peculiar characteristics of my In-
vention. I claim as my Invention in shuttles, arrangements whereby the
spring employed to act on the shank of the tongue or peg to hold it in the
required positions, is made to exert a pressure on the interior of the cop or
bobbin when in the position for weaving, by pressing upon the swell (a¹), or
part corresponding to the swell (a'), of shuttle tongues or pegs directly, or by
the intervention of a piece corresponding to the lever piece f.
In witness whereof, I, the said John Barton, have hereunto set my
hand and seal, this Twentieth day of June, in the year of our Lord
One thousand eight hundred and fifty-six.
