I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool and 6 Bank Street,
Manchester both in the County of Lancaster and 323 High Holborn in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this
invention to be as follows:-
The always evident need of rendering less unhealthy the work of the female
weavers has already caused a large number of hygienic appliances to be invented
for removing the causes of the numerous maladies which, unfortunately, are
prevalent in various industries.
The arrangement forming the object of this invention is designed to do away
with the sucking up of the threads by the mouth in order to insert them in the
eyelets, the effect of which is, as may easily be seen, to cause the dust deposited ou
the shuttle to enter the lungs, which is very injurious to health. This object,
which it is desired to attain, meets, in practice, with several difficulties; in the
arrangements previously invented, the hygienic advantage was obtained either by
means of complications in the shuttle itself, or by having recourse to auxiliary
appliances which caused much loss of time. If it be remembered that the operative
during her work must not have her attention drawn away, it will easily be seen
that a shuttle, in order to present the qualities hereinbefore enumerated, must,
above all, be very simple.
These advantages are obtained in this improved shuttle. The spindle is inserted
in the shuttle in the usual manner, that is to say, movably, ou springs, on an axis
parallel to the plane of the movement, and perpendicular to the direction of the
latter. The bobbin (spool) is fixed on this spindle, also in the ordinary manner by
raising the spindle, which is done by inserting the fingers in the lower opening of
the shuttle and pushing it upwards.
The spindle is then brought back to its ordinary position by means of the
expansion of a spring. This improved arrangement is situated near the eyelet at
the corresponding end of the shuttle. It consists, above all, in the substitution for
the eyelet of an actual slot which is prolonged up to the upper side of the shuttle,
and which allows the thread to be inserted without any difficulty when the end is
held in the hands. When the thread is inserted in the eyelet, it is necessary that
it shall not be able to slip out again, which it would do, doubtless, if the slot
remained open.
With this object, the slot is closed by the arm of a movable
spring hinge piece which serves to enclose the thread in an actual conduit in which
it can slide as freely as in the ordinary shuttles. It is also necessary that the
thread, in its movement, should encounter the least possible resistance, which is
obtained in the following manner :-
The thread, on leaving the bobbin, spreads along the axis of the movement, and
enters into a framing, which is itself covered by the hinge. When the thread
comes opposite the slit which serves as eyelet, it is bent round at right angles by
pressing on a little wire hook it then enters the slot and passes out of the shuttle.
On the outer side of the eyelet, an assistant wire crook is arranged, encased in the
slot, which serves as a final support for the thread; in this manner, the thread, in
unwinding from the bobbin, reaches the first hook and immediately afterwards
the end of the eyelet, without touching the shuttle at any other point. In
order to prevent the thread from changing its points of support, the first hook

page_text: is bent back in the form of an arc. With the arrangement hereinbefore described,
it is very easy to insert the thread in the eyelet; for this purpose, it suffices to
open the hinge arranged on the upper side of the shuttle, raise the spindle, fit
the bobbin thereon and return it to its ordinary position. The thread, which
unwinds from the bobbin, is held by the fingers of the right hand, and, using one
finger of the left hand on which the thread rests, the latter is inserted in the hook
and then placed in the slot, forcing it to pass into the section of the eyelet. The
hinged piece is then shut down, and the shuttle is ready to be used.

I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6 Bank Street, Manchester,
both in the County of Lancaster and 323 High Holborn in the County of
Middlesex, Civil Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :--
The always evident need of rendering less unhealthy the work of the female
weavers has already caused a large number of hygienic appliances to be invented
for removing the causes of the numerous maladies which, unfortunately, are
prevalent in various industries.
The arrangement forming the object of this invention is designed to do away
with the sucking up of the threads by the mouth in order to insert them in the
eyelets, the effect of which is, as may easily be seen, to cause the dust deposited on
the shuttle to enter the lungs, which is very injurious to health.
This object,
which it is desired to attain, meets, in practice, with several difficulties; in the
arrangements previously invented, the hygienic advantage was obtained either by
means of complications in the shuttle itself, or by having recourse to auxiliary
appliances which caused much loss of time. If it be remembered that the operative
during her work must not have her attention drawn away, it will easily be seen
that a shuttle, in order to present the qualities herein before enumerated, must,
above all, be very simple.
These advantages are obtained in this improved shuttle, which is shown on the
accompanying drawing-
Figure 1 being a plan view of the front part of the shuttle with the hinge piece
closed;
Figure 2 a plan view of the same part of the shuttle with the hinge piece
raised;
Figure 3 a longitudinal section of the shuttle on line A. B, Figure 2, and
Figure 4 a section of the shuttle on line D G.
The spindle is inserted in the shuttle in the usual manner, that is to say, movably,
on springs, on an axis parallel to the plane of the movement, and perpendicular to
the direction of the latter. The bobbin (spool) is fixed on this spindle, also in the
ordinary manner by raising the spindle, which is done by inserting the fingers in
the lower opening of the shuttle and pushing it upwards.
The spindle is then brought back to its ordinary position by means of the
expansion of a spring. This improved arrangement is situated near the eyelet at
the corresponding end of the shuttle. It consists, above all, in the substitution for
the eyelet of an actual slot which is prolonged up to the upper side of the shuttle,

page_text: and which allows the thread to be inserted without any difficulty when the end is
held in the hands. When the thread is inserted in the eyelet, it is necessary that
it shall not be able to slip out again, which it would do, doubtless, if the slot
remained open. With this object, the slot is closed by the arm d of a movable
spring hinge piece c pivoted at which serves to enclose the thread in an actual
conduit in which it can slide as freely as in the ordinary shuttles. It is also
necessary that the thread, in its movement, should encounter the least possible
resistance, which is obtained in the following manner :-
The thread, on leaving the bobbin, spreads along the axis of the movement, and
enters into a framing, which is itself covered by the hinge, c. When the thread
comes opposite the slit which serves as eyelet, it is bent round at right angles by
pressing on a little wire hook a: it then enters the slot and passes out of the shuttle.
On the outer side of the eyelet, an assistant wire crook is arranged, encased in
the slot which serves as a final support for the thread; in this manner, the thread,
in unwinding from the bobbin, reaches the first hook a and immediately afterwards
the end of the eye slot, without touching the shuttle at any other point. In order
to prevent the thread from changing its points of support, the first hook a is bent
back in the form of an arc. With the arrangement hereinbefore described, it is
very easy to insert the thread in the eyelet; for this purpose, it suffices to open
the hinge arranged on the upper side of the shuttle, raise the spindle, fit the bobbin
thereon and return it to its ordinary position. The thread, which unwinds from
the bobbin, is held by the fingers of the right hand, and using one finger of the
left hand on which the thread rests, the latter is inserted in the hook a and then
placed in the slot b, forcing it to pass into the section of the eyelet. The hinged
piece is then shut down, and the shuttle is ready to be used.

Figure 3 shows how the thread is inserted beneath the hook a by holding it
with one finger until the end is lodged in the slot of the eyelet: the hinge piece
is then shut down and held by a spring e and the end of the thread pulled, when
the latter will be placed on the lower part of the arc hook a, that is to say, in its
final position.
Modifications may of course be introduced in the details of this invention without
affecting its essential principle.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
1. An improved shuttle for looms in which the necessity for sucking up the
threads by the mouth in order to insert them in the shuttle is avoided by the
substitution, for the usual eyelet, of a slot extending to the upper side of the shuttle,
the slot being closed by means of a hinged piece acting under spring pressure, with
the object of preventing the thread from slipping out, substantially as herein before
described and shown on the accompanying drawing.
2. In an improved shuttle such as described in Claim 1, the arrangement for
facilitating the passage of the thread consisting of a recess which is covered by the
spring hinge c, into which recess the thread passes after leaving the bobbin, and of
a little wire hook round which the thread passes before leaving the shuttle through
a suitable slot, in which latter the thread is preferably guided and supported by
means of a second wire crook, substantially as described and shown.
