Year: 1865

page_text: LETTERS PATENT to Demas Ellis and Matthew Hillas, of Dudley Hill,
Bradford, Yorkshire, Manufacturers, for the Invention of "IMPROVE-
MENTS IN APPARATUS EMPLOYED IN WEAVING BROCADED AND ORNAMENTAL
FABRICS."
Sealed the 7th November 1865, and dated the 11th May 1865.
PROVISIONAL SPECIFICATION left by the said Demas Ellis and Matthew
Hillas at the Office of the Commissioners of Patents, with their Petition,
on the 11th May 1865.
We, DEMAS ELLIS and MATTHEW HILLAS, of Dudley Hill, Bradford, York-
shire, Manufacturers, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN APPARATUS EMPLOYED IN WEAVING BROCADED AND ORNA-
MENTAL FABRICS," to be as follows:-
This Invention has for its object improvements in apparatus employed in
weaving brocaded and ornamental fabrics, and consists in certain construc-
tions and arrangements of the apparatus used for introducing the weft in such
fabrics as hereafter explained. For these purposes a swivel shuttle used in
swivel shutting brocading, is arranged to receive in one part a bobbin barrel,
cylinder, coiler, or clue, on to which, as heretofore, the weft to be intro-

page_text: duced into the woven fabric is wound, and in another part of the shuttle
another bobbin barrel, cylinder, coiler, or clue is introduced, on to which the
weft passes and the drag on the weft is thereby regulated.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
.
by the said Demas Ellis and Matthew Hillas in the Great Seal Patent
Office on the 10th November 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, DEMAS
ELLIS and MATTHEW HILLAS, of Dudley, Hill; Bradford; Yorkshire, Manu-
facturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of May, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Demas Ellis and Matthew-Hillas,-Her special licence, that we,
the said Demas Ellis and Matthew Hillas, our executors, administrators,
and assigns, or such others as we, the said Demas Ellis and Matthew
Hillas, our exécutors, 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, withini the. United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
APPARATUS EMPLOYED IN WEAVING BROCADED AND-ORNAMENTAL FABRICS," upon the
condition (amongst others) that we, the said Demas Ellis and Matthew Hillas,
our executors or administrators, by an instrument in writing under our, or
their hands and seals, or under the band and seal of one of us or them, 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 we, the said- Demas Ellis, and Matthew Hillas, do
hereby declare the nature of the said Invention, and in what, manner the
same is to be performel, to be particularly described and ascertained in and
by the following statement thereof, that is to say :-
This Invention has for its object improvements in apparatus employed in
weaving brocaded and ornamental fabrics, and consists in certain construc-
tions and arrangements of the apparatus used for introducing the weft in such

page_text: fabrics as hereafter explained. For these purposes a swivel shuttle used in
'swivel shuttle brocading is arranged to receive in one part a bobbin barrel;
cylinder, coiler, or similar instrument, on to which, as heretofore, the weft to be
'introduced into the woven fabric is wound, and in another part of the shuttle
another bobbin barrel, cylinder, or similar instrument is introduced on to
which the weft passes, and the drag on the weft is thereby regulated.
Figure 1 is a plan, and Figure 2 a transverse section of a swivel brocading
shuttle arranged according to our Invention. a, a, is the body of the shuttle,
it is usually made in boxwood, a' are rack teeth formed therein to receive
the rack by which the shuttle is actuated; 6 is a bobbin on which the weft
is wound, it is as is usual carried upon a pin c, coiled to form a spring at one
end, where it is held in a notch in the shuttle body, its other end enters a
groove in the shuttle body and springs into a recess; at the bottom of this
groove d is a wire also held at one end in a notch in the shuttle body, it is by
a spring e (which is made in one piece with the pin c,) caused to bear lightly
on the surface of the bobbin b, this arrangement is employed as heretofore to
prevent the bobbin turning too freely; f is a barrel let into a recess formed
for it in the shuttle body around its axis or centre, and fixed thereto at one
end is a coiled spring g, the other end of which is fixed to the shuttle body; h
is a metal plate let into the shuttle body, and forming the bottom of the
recess in which the barrel f is contained; i is a metal strap embracing the
'neck of the barrel f, and attached by screws to the shuttle body, it holds the
barrel fin its place. The weft as it is drawn from the bobbin 6 passes down
the hollow neck of the barrel f, and through the passage f¹ to the periphery
of the barrel; it makes about a turn and a half, or it may be more, around
the barrel, and is led out through the eye a³ at the front of the shuttle body.
It will be seen that when the shuttle is at work and a strain comes on the
weft the barrel f turns, winding up the spring 9 until its tension is sufficient
to draw off weft from the bobbin 6, and then afterwards when the pull on the
weft ceases at the return motion of the shuttle, the barrel f winds up
again on to itself so much of the weft as would without this arrangement
be for the moment left slack, and thus sudden strains on the weft are
avoided.
Figure 3 is a plan, and Figure 4 a longitudinal section of another similar
arrangement where the weft is wound upon an upright barrel; a is the body
of the shuttle in which two recesses are formed, they are closed at the bottom
by the metal plate h, in which are holes to receive the centre pins or studs of
the barrels b and f, which are contained in the recesses. The weft is wound
upon the barrel b, which is kept in its place by a spring cross wire k, held at

page_text: one end in a hole in the shuttle body, and at the other end catching into a
notch therein. The barrel f is furnished with a spring 9, and is otherwise
arranged in the manner described as respects Figures 1 and 2. The weft is
led from the barrel 6 through the passage a¹ in the shuttle body, thence down
through the neck of the barrel f, and through the passage f¹, therein then as
before it makes a turn and a half or thereabout around the barrel, and it
issues by the eye a².
Figure 5 is a plan of another arrangement suitable for taking weft wound
into small cops; a is the body of the shuttle, and 1 is a spring pin or brooch,
on which the weft cop m is placed, this pin l is wound into a spiral near its
inner end to give it sufficient elasticity, and it is fixed in a notch in the
shuttle body; f is a roller which contains a spiral spring, and turns on a
stud n fixed to the shuttle body, the spring is fixed at one end to the roller,
and at the other to the stud n, on which the roller turns, so that the spring
allows the roller to revolve several times before the spring is fully wound up.
The weft passes from the cop to an eye in the end of the roller, it passes
through this eye, and out at another eye in the side of the roller, the weft then
takes three or other number of turns around the roller and then passes to the
eye a at the front of the shuttle.
It will be seen that in each of these arrangements the same principle is main-
.tained of causing the weft after it is drawn from the bobbin or instrument on
which it is wound to pass around another bobbin or similar instrument, which
is provided with a spring, causing it to wind up any weft which otherwise
would beconie slack.
In witness whereof; we, the said Demas Ellis and Matthew Hillas, have
hereunto set our hands and seals, this Third day of November in the
year of our Lord One thousand eight hundred and sixty-five.
