Year: 1876

page_text: LETTERS PATENT to Edward Heywood Stutter, of Arundel, in the County of
Sussex, Joseph Stubbs, of Manchester, in the County of Lancaster, Machine
Maker, and John Corrigan, of the same Place, Mechanic, for the Invention of
"IMPROVED APPARATUS FOR THREADING OR PASSING WEFT YARNS OR THREADS
THROUGH THE EYES OF SHUTTLES USED IN LOOMS FOR WEAVING."
COMPLETE SPECIFICATION filed by the said Edward Heywood Stutter, Joseph
Stubbs, and John Corrigan at the Office of the Commissioners of Patents on
the 6th October 1876.
EDWARD HEYWOOD STUTTER, of Arundel, in the County of Sussex, JOSEPH
STUBBS, of Manchester, in the County of Lancaster, Machine Maker, and JOHN
CORRIGAN, of the same Place, Mechanic. "IMPROVED APPARATUS FOR THREADING
OR PASSING WEFT YARNS OR THREADS THROUGH THE EYES OF SHUTTLES USED IN
LOOMS FOR WEAVING."
This Invention consists in the arrangement and construction of a simple and
economical apparatus for producing a partial vacuum, to be employed for drawing
or sucking the yarn or thread through the eye of the shuttle, and thereby avoid the
necessity of the operative drawing or sucking the end through the eye by a deep
inspiration of the breath, a practice which is well known to cause disease and
sometimes death.
The apparatus consists of two sheet metal cylinders one within the other, with
only sufficient space between the two to allow the inner one to be moved up and
down or to and fro.
The outer cylinder is held firmly to the framework of the loom, and has at the
bottom a central tube through which is passed a suction tube fixed to the top of
the internal cylinder, and when the end of the yarn or thread is placed against one
side of the eye, and the other side of the eye pressed against the suction tube, and
the tube and cylinder pressed up, down, or sideways, the internal cylinder moves
out of the external one and gives sufficient vacuum to immediately draw the end
through the eye of the shuttle.
On the accompanying Sheet of Drawings Fig. 1 is an outside view of our improved
apparatus for threading shuttles, and Fig. 2 a section of the same,

page_text: The apparatus consists of two sheet metal cylinders a, d, one within the other,
with only sufficient space between the two to allow the inner one to be moved up
and down.
The outer cylinder a is fixed or held firmly to the framework of the loom by the
bracket 6 cast or fixed to the disc c, the internal cylinder d having a weighted
cover e placed at the top, to which is fixed a central suction tube f, having holes g, h,
near the top of the internal cylinder d.
When the eye of the shuttle is placed to the mouth-piece j, and the end of the
weft or yarn is placed against one side of the eye, and the shuttle pressed up
sufficient vacuum is caused to immediately draw the end of the weft or yarn
through the eyes of the shuttle.
Although we have only shewn the apparatus in a vertical position it may be
placed horizontally or at any required angle, and if desired the two cylinders can
be held in their contracted positions by springs or weights.
Having now described the nature and particulars of our said Invention, we
desired it to be understood that we claim, the improved apparatus for threading
or passing weft yarns or threads through the eyes of shuttles used in looms for
weaving, as herein-before described and illustrated on the accompanying Sheet of
Drawings or any mere modification thereof.
In witness whereof, we, the said Edward Heywood Stutter, Joseph Stubbs,
and John Corrigan, have hereunto set our hands and seals, this Twenty-
seventh day of September, in the year of our Lord One thousand eight
hundred and seventy-six.
