Improvements in Weaving Shuttles.
A communication from abroad by XAVIER DÉPIERRE, of 19, Rue Cambon, Paris,
France, Manufacturer.
I, JOHN CORRY FELL, of the Firm of Fell and James, of 1, Queen Victoria
Street, London, E.C., Chartered Patent Agent, do hereby declare the nature
of this invention and in what manner the same is to be performed to be parti-
cularly described and ascertained in and by the following statement; -
This invention relates to an improvement in weaving shuttles and has for
its object the production of a better tension in the shuttle thread and a more
true and perfect selvage to the fabric.
In shuttles as at present in use, the shuttle thread is passed through an eye
of porcelain or metal or through a hole pierced through the shuttle with splayed
and rounded edges, pierced about 15 or 20 millimetres beyond the point of the
shuttle bobbin which holds the shuttle thread or weft.
The thread passing through this eyelet or hole lies during the travel of the
shuttle in a recess on one side of the shuttle and thus is protected from rubbing
during the entry or exit of the shuttle to or from the shuttle box.
This known system however produces only imperfect selvages in the fabric,
and necessitates the employment of appliances to give greater tension to the
thread
To avoid these inconveniences the improvement has been devised as herein-
after fully described with reference to the drawings annexed hereto.
Figure 1 shows a
plan of a shuttle as at present in use with the said improve-
ment added, the shuttle thread passing through a hole placed in a side slot or
recess of the shuttle.
Figure shows a side elevation of the same.
Figure 3 is a plan of a shuttle especially designed for the said new improve-
ment, the shuttle thread passing through a hole in the bottom of the shutle and
Figure 4 is a broken vertical section through the same following the
line 1, 2, 3.
To carry out this invention, at a distance of about 15 to 20 millimetres in
front of the point of the bottom p is placed a screw or hook or an equivalent
in any suitable metal through or over which the thread f from the bobbin is
caused to pass. Where this fitting is adapted to a shuttle as already in use as
in Figs. 1 and 2 with a side recess or groove r adapted to protect the thread
during work, a hole is pierced about 15 or 20 millimetres behind the point of
the bobbin spindle the shuttle or weft thread is passed through it the hole
being situated exactly in the centre of the said recess or groover at the side of
the shuttle.
In this way a better tension on the thread is obtained and by this fact selvages
absolutely straight and perfect in the fabric result.
Equivalently the same screw or hook as before described is applied to a
shuttle especially designed for the purpose and the shuttle thread f' is brought

page_text: out through a hole a pierced in the bottom of the shuttle under the end of the
bobbin spindle about 10 or 20 millimetres behind the point of the spindle.
The thread will lie at its issue in a recess or groove in the base of the shuttle
and will be thus protected from rubbing during work.
By this last arrangement a recess or groove at one side of the shuttle is dis-
pensed with, thus preserving all the strength to the wood and enabling such
shuttles to be utilized either to the right or left of the looms.
By both these arrangements the same perfect result as regards the selvages
is attained and further the thread is prevented from becoming hooked over the
picker as so frequently happens.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1st. The combination in a shuttle for weaving of a screw, hook or equivalent
placed in front of the bobbin spindle adapted to receive and guide the shuttle
thread and an orifice for the issue of the thread, placed a short distance behind
the point of the bobbin spindle, substantially as and for the purposes described.
2nd. A weaving shuttle, without side external recess or groove for the recep
tion of the shuttle thread, having, in combination, a screw, hook, or equivalent,
fitted in front of the bobbin spindle, adapted to receive and guide the shuttle
thread, an exit hole for the shuttle thread under the bobbin spindle placed a
short distance behind the point of the said spindle, and a recess or groove about
the said exit hole in the bottom of the said shuttle, substantially as and for the
purposes described.
