Improvements relating to the Threading of Loom Shuttles.
I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:-
This invention relates to a device for threading shuttles of looms.
The frequency of chest and throat diseases among weavers and the complaints
which they make of their lungs being fatigued by reason of the energetic and
continued sucking of the weft thread through the eyes or holes in the shuttle have
induced me to study the mode of threading the shuttle so as to avoid the sucking
the thread.
The solution of this problem has been subordinated to the conditions viz., not to
change the mode of development of the thread on leaving the shuttle; not to
increase the difficulty of the threading operation; not to increase the time
required; and not to necessitate any attention on the part of the weaver.
This object is obtained by a simple threader needle or a hook, some slight modifi-
cations being also made in the form of the shuttle.
The aforesaid threader needle is formed of three metallic strips soldered together
in their middle and diverging from each other at their extremities to such an
extent that the thread which is wound from the bobbin may without difficulty pass
between any two of the four couples of branches formed, without any necessity
for the weaver to keep his eyes on the thread.
As soon as the thread has passed. between the branches of the threader needle
the weaver can pass it with the greatest facility through the small eyes or holes in
the shuttle without having to suck the wire through these eyes or holes, as has
heretofore been the case.
The shuttle does not differ from those ordinarily used save that it is provided
with recesses designed to facilitate the introduction of the threader needle or the
hook. It may be provided with either one or two holes in the latter case the
thread may pass through one only, or first through one and then through
the other.

COMPLETE SPECIFICATION.
Improvements relating to the Threading of Loom Shuttles.
I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, do hereby
declare the nature of this invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained, in and by the following
statement:—
This invention relates to a device for threading shuttles of looms.
The frequency of chest and throat diseases among weavers and the complaints
which they make of their lungs being fatigued by reason of the energetic and
continued sucking of the weft thread through the eyes or holes in the shuttle have

page_text: induced me to study the mode of threading the shuttle so as to avoid the incon-
veniences above stated.
The solucion of this problem has been effected subject to the following
conditions, vic., that no change is made in the mode of development of the thread
on leaving the shuttle; that the difficulty of the threading operation is not
increased; that the time required is not increased and that no attention is necessary
on the part of the weaver.
In the accompanying drawing I have shown how my said invention may be
conveniently and a:lvantageously carried into practice:
Figure represents a needle constructed according to my invention for threading
the shuttle.
Figure 2 represents a hook for this purpose.
Figure 3 is tubular pocket adapted to be attached to the front of the loom
to receive the said needle or hook.
Figure 4 is a rear side view of a shuttle.
Figure 5 is a front view of the saine.
Figure 6 is a section of the same on the line ttuu of Figure 5, and
Figure 7 is a section on the line of Figure 4.
The device employed for threading the shuttle consists either of a needle a
similar to that shown in Figure 1 or of a hook 6 as shown in Figure 2.
Figure 3 is a needle holder or pocket which is attached to the front of the
loom in such a position as to be easily accessible to the operator when desired.
The shuttle shown is slightly modified to enable the threader needle or hook to
be used therewith.
The aforesaid threader needle a is formed of three metallic strips at a³ a³
soldered together at their middle and diverging from each other at their extremities
to such an extent that the thread which is wound from the bobbin A may without
difficulty pass between any two of the strips without the necessity of the weaver
keeping his eyes on the thread.
As soon as the thread has passed between any two of the strips of the threader
needle the weaver can pass it with the greatest facility through the small eyes or
holes in the shuttle without having to suck the wire through these eyes or holes, as
has heretofore been the case.
The shuttle does not differ from those ordinarily used save that it is provided
with the recesses k, k' and 2 shown in the drawing to facilitate the introduction of
the threader needle or the hook into the holes through which the weft thread is to
pass.
The thread is made to pass through hole d, e, or through hole f, g, first and then
through hole h, i.
It is understood that in practice the shuttle is provided either with one hole or
with two holes, or the said shuttle may be provided with all the holes above
mentioned.
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 :-
The method of threading loom shuttles by means of needles or hooks so as to
dispense with the sucking action heretofore exerted by the weaver, substantially as
hereinbefore described with reference to the drawing.
