Partington, Overlooker, William Partington, Mechanic, all of
the City of Manchester, in the County of Lancaster, for the
Invention of " TEPDADEMENME TE SHUTTLES FOR WEAVING ”
PROVISIONAL SPECIFICATION left by the said John Wolstenholme,
Thomas Partington, and William Partington at the Office of the
Commissioners of Patents, with their Petition, on the 15th
September 1875..
We, JOHN WOLSTENHOLME, Shuttle Maker, THOMAS PARTINGTON,
Overlooker, and WILLIAM PARTINGTON, Mechanic, all of the City of
Manchester, in the County of Lancaster, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN SHUTTLES FOR WEAVING,"
to be as follows:-
--
The object of our Invention is to dispense with the necessity for
sucking the end of the weft through the eye or eyes of the shuttle,
which is so prejudicial to the health of the weavers, as the loose fibres

page_text: Our Invention consists in arrangements by which the weft from the
cop or bobbin can be passed by hand, almost instantly through the eye
of the shuttle; such arrangements being formed by a bolt passing
through a bush in the shuttle, and having a spring round it to draw the
head of the bolt against the edges of a cavity formed in the shuttle.
When the weft is to be threaded this sliding bolt is forced outwards by
the finger of one hand while the weft is passed round the head of the
bolt by the other hand, the weft passing into the eye through a cut or
gap in its side. The head of the bolt has two projections, one which
closes the gap or space in the side of the shuttle for the weft to pass to
the eye when the spring draws in the bolt, and the other to keep down
the weft against a wire pin.; this projection and the pin giving the
required drag to the weft.
•
The bolt may be secured to a bent flat spring, if desired, dispensing
with the coiled spring and the bush. Or a piece acting in place of the
bolt may be arranged to turn on a fulcrum pin, the tail of this piece
being acted upon by a spring. Or in place of the arrangements above
described the eye may
y be formed by a "curl" somewhat similar to that
upon the leg of a throstle flyer, the parts for giving drag and guiding
the-weft-to-the-curl-being-fixed.

Letters Patent, bearing date the Fifteenth day of September, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said John Wolstenholme, Thomas
Partington, and William Partington, Her special license that we, the
said John Wolstenholme, Thomas Partington, and William Partington,
executors, administrators, and assigns, or such others as we, the
said John Wolstenholme, Thomas Partington, and William Partington,
our 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 SHUTTLES FOR WEAVING," upon the condition (amongst
others) that we, the said John Wolstenholme, Thomas Partington, and
William Partington, our executors or administrators, by an instrument
in writing under our, 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 we, the said John Wolstenholme, Thomas
Partington, and William Partington, 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 and the accompanying Drawings (that is to say) :-
The object of our Invention is to dispense with the necessity for
sucking 'the end of the weft through the eye or cyes of the shuttle,
which is so prejudicial to the health of the weavers, as the loose fibres
and other deleterious matters from dyed weft in the eyes of the shuttle
are liable to pass to the lungs in such operation, and besides accom-
plishing this object we save waste of weft, balance the shuttle, and arc
able to adjust the tension or drag upon the weft, and thus improve the
weaving.

of the shuttle; such arrangements being formed by a bolt passing
:through a bush in the shuttle, and having a spring round it to draw the
head of the bolt against the edges of a cavity formed in the shuttle.
When the weft is to be threaded this sliding bolt is forced outwards by
the finger of one hand while the weft is passed round the head of the
bolt by the other hand, the weft passed into the eye through a cut or
gap g'in its side. The head of the bolt has two projections, one which
closes the gap or space in the side of the shuttle for the weft to pass to
.the eye when the spring draws in the bolt, and the other to keep down
the weft.
The bolt may be secured to a bent flat spring, if desired, dispensing
with the coiled spring and the bush; or a piece acting in place of the
bolt may be arranged to turn on a fulcrum pin, the tail of this piece
being acted upon by a spring; or in place of the arrangements abovė
described the eye may be formed in a thin metal lever acted upon by a
spring, a narrow space being left in the side of the shuttle for the weft
to enter the eye.
Fig. 1 is a plan of one end of a shuttle, full size; Fig. 2, a side view;
Fig. 3, a cross section; and Fig. 4, a longitudinal section, illustrating
.one modification of our Invention.
Figs. 5, 6, 7, and 8, are views corresponding respectively to Figs. 1,2,
3, and 4, of another modification; and Figs. 9, 10, 11, and 12, and
Figs. 13, 14, 15, and 16, are views corresponding respectively to Figs.
1, 2, 3, and 4, of two other modifications of our Invention.
•
In Figs. 1, 2, 3, and 4, a hole is made through the shuttle and
enlarged at each side, as shown, and a metal .bush (a) like an eyclet is
inserted-for-the-stem-of-the-bolt-b-to-slide-in-the-bevelled-head-of-this-
bolt being drawn-against the countersunk bevel in the wood of the
shuttle by a spring c round the stem of the bolt, acting against the
bush (a) on one side, and the nut d of the bolt on the other side, the
latter being screwed on to the stem by means of a two pronged screw-
driver fitting two holes in the head of the nut for which there is an
enlargement in the wood of the shuttle that allows the head of the nut
to be pushed outwards to the extent required, as shown; e is the
ordinary shuttle tongue upon which the cop, bobbin, or pirn, is placed ;
f is a part from the bolt head which keeps the weft down as it passes
from the cop partly round the stem of the bolt, and then through, the

page_text: eye f: This eye (f) has a gap or space in it filled by a part * from
the head of the bolt when it is drawn in by the spring (c) after the
weft has been placed in the eye (f).
Figs. 5, 6, 7, and 8, show another modification where a lever is
employed. This lever has its fulcrum on a pin 6* passing through the
shuttle, and it has a projecting arm 63 that is acted upon by a spring c
inserted in a hole made in the wood of the shuttle, as shown by
pressing upon this arm b³ of the lever it is lifted to allow the weft to be
passed under the lever and through the space into the eye of the
shuttle. The lever b has a projection from it which fills the gap or
space in the eye and side of the shuttle when the spring c is allowed to
force the lever down. The weft passes from the cop round a wire ping,
and then through the eye f. There is an horizontal wire pin h coming into
a groove in the under side of the flat part of the lever which prevents
the weft from rising too high.
.
The modifications shown by Figs. 9, 10, 11, and 12, and Figs. 13, 14,
15, and 16, are similar to each other and only differ in the form of the
lever. The levers in these modifications may be stamped out of sheet
metal, or formed in cast metal if desired. The lever (b), Figs. 9, 11,
and 12, has its fulcrum on a wire pin 6* passing through the wood of
the shuttle; it may be cut out of flat metal and bent to the form shown.
It has a hole and slit in it for the weft to pass through, corresponding
with the hole in the eye ƒ for the weft. This eye in the lever has a
narrow space for the weft to pass through and it corresponds in position *
to a similar space cut at an angle at the side of the shuttle for the weft
to pass through. When one arm of the lever b is pressed, the end of
its other arm comes above the upper surface of the wood of the shuttle,
and the weft is then passed round, and in this position of the lever
the slit in the lever passing to the hole in it, for the weft is opposite.
the slit in the side of the shuttle, consequently the weft can pass
into the hole in the lever, and at the same time into the "eye.” When
the spring c is allowed to bring down the lever the slits are not opposite
but as shown in Fig. 12, so that the weft can pass through in weaving,
but cannot get out of the eye (f) sideways.
In Figs. 13, 14, 15, and 16, there is a washer or boss on one side of
the fulcrum wire b* on which the lever works, and the spring c acts
against the edge of the projecting arm 6³ of the lever, the projecting
