An improved Device for Threading weavers putties.
I ADOLF HARDMEYER, of Goerz, in the Empire of Austria, Director, 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:-
Hitherto the threading of weavers' shuttles has had to be effected by the person
attending to the loom, the eye of the shuttle being placed to the mouth and the
loose end of the thread wound on a bobbin or spool being then drawn through by
strong suction. This operation, which as is well known is very frequently
necessary, not only causes severe exertion but also is deleterious to health as by
the suction or inhalation fine dust particles such as accumulate in shuttles con-
stantly in the form of fine particles of thread or fibres are drawn into the lungs.
Numerous experiments have been made to effect this drawing in of the thread
by means of apparatuses which had to be set in action as soon as the threading
became necessary by means of pressure by the hand or by the foot, or which were
connected with the loom and operated from the latter, by which connection of
course the practical handling of the loom itself was rendered more difficult.
All these separate arrangements which are exclusively intended for use with a
loom and which have to be operated; when threading is necessary, by a special or
separate pressure push or the like, have moreover the drawback that particles of
thread, dust and the like torn off accumulate therein which interfere with the
working of the separate parts so that a constant certain working of these devices
or apparatus is prevented.
This invention has for its object an arrangement which is shown in the accom-
panying drawings which effects the drawing in as will appear from the following
specification in an independent, automatic, certain, convenient and extremely
rapid manner.
The arrangement consists of a pipe or rather of a series of pipes A connected as
shown in Figure 1, with a suction apparatus B in the form of a fan, pneumatic
ball, suction pump or the like which produces in the interior of the series of pipes
a vacuum, and which series of pipes is so arranged in any suitable manner in the
weaving room or shed that it may be conveniently reached from any loom.
In this above mentioned series of pipes, small openings (holes) are formed at
suitable places and in proximity thereto bye-passes or attachments of the kind
shown in Figures 34, 3, 3° or other suitable form mounted in such a way on the
pipe that as soon as the shuttle is inserted with its point in such an attachment or
projection it lies with its eyelet exactly on the hole there formed in the pipe.
In place of simple openings, suction pipes of straight or bent form may be
inserted in the series of pipes either directly in the pipe A or on shaped pieces C,
such as shown as an example in Figure 2 in side view partly in section and in
Figure 3 in plan view, the said shaped pieces being inserted or connected with the
pipe A, the open ends of the said small suction pipes being formed to suit the

page_text: eyelets of the shuttles. To these small suction pipes in turn in immediate proximity
the already mentioned connections or fittings are mounted and fixed at a suitable
height on the pipe or rather on the shaped pieces C, so that on the insertion of the
end of the shuttle in the connection the eyelet-is directed or fitted exactly on the
suction, pipe standing in front of it.

The above mentioned inserted shaped pieces C shown in Figure 2 are short pipes,
the ends of which are inserted or connected in the pipe A by means of a screw
thread c formed thereon to engage in nuts a plugs or flanges.
In addition to the attachments shown in Figures 3* 3° 3° support pieces may be
mounted or cast on the pipe or rather on the shaped pieces C in order to enable
the shuttle which is to be threaded to be inserted more conveniently. Such a
shuttle receiving addition ² cast on the shaped piece C is shown for instance in
Figure 3.
. "
The person attending to the loom, in order to thread the shuttle need only insert
the end of the shuttle which is provided with the eyelet into a suitably formed
attachment, whereupon the eyelet will itself lie with the thread or yarn end which
is to be threaded on the opening or rather on the pipe cl, and the constantly
working suction apparatus B will at once draw the end of the thread through the
...eyelet.
If the pipe A for any reason be laid along the floor or on the ceiling or along
the walls instead of having its arrangement as was hereinbefore assumed running
along the looms immediately at the correct height for use, stand pipes or branch
pipes are inserted therein, the ends of which are carried to the places where the
apparatus is to be used and in which the openings to, or rather the suction pipes e,
together with the fittings or attachments hereinbefore described, must be attached
in a suitable manner.
In addition to the optional shaped pieces C or rather the small pipes c', one or
more boxes D may also be inserted in the pipe, which boxes are closed by means
of lids d to keep out the dirt but in such a way as to be accessible and are provided
internally with sieves or strainers E, as shown in Figures 4 and 5, (which are
respectively a longitudinal section and cross section of such a box). These boxes
form filter boxes and have for their object to catch particles of dust, pieces of
thread and the like drawn in through the pipes c¹ in order that such particles
may not pass into the suction apparatus B.
The sieves E which may have a rectangular form as shown in Figures 8 and 11,
pyramidal as in Figure 6, conical as in Figure 7, or be of other suitable form may
be all of equal fineness in the box D or may alternate in series according to the
fineness so that for instance at the entrance to the box Figure 4 on the left hand
side, a sieve of the fineness shown in Figure 8 is employed, to which the sieve
shown in Figures 9, 10 and 11 follow so that the last sieve is the finest and retains
the finest particles of dust. In this manner it is possible to retain the finest
particles in the box D without the sieve becoming too rapidly choked.
The opening at one side of each sieve has for its object to diminish as little as
possible the inlet diameter in the box D. As may be seen in Figure 5, the
sieves E are inserted in the box 1) in such a way that the opening of the first
sieve stands for instance to the left, that of the second sieve to the right, that of
the third sieve again to the left and so forth. Moreover for instance in Figure 5,
the foremost sieve E is of the fineness of the one in Figure 9, with a left hand
opening, the sieve standing behind (with its opening to the right) is shown of the
fineness of Figure 10. In this way the air is not compelled to simply move in
'the box D through the meshes of the sieve, but it is also free to flow between the
sieves through the alternate openings therein which self evidently considerably
diminishes the friction of the air in the said box.
It is apparent from the foregoing that the position, arrangement and fitting of
this pipe or piping or rather of this series of pipes A and also of the filter boxes D
with the sieves E, for the present object may undergo considerable modifications
without thereby proceeding beyond the scope of the invention.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is:
1. A device for threading weaving or weavers' shuttles consisting of a pipe or
series of pipes (A) closed at the end and connected with a constantly acting suction
apparatus (B), which pipe (A) is provided with suitable openings or rather with
suction pipes (c) fitting the eyelets of the shuttles in such a way that the drawing
or suction of the end of the yarn or thread through the eyelet, that is to say the
threading of the shuttle, may be effected automatically by means of the vacuum
constantly present in the series of pipes the moment the eyelet of the shuttle is
brought into communication with one of the said openings or suction devices (c¹)
substantially as herein before described.
2. A device for threading weavers' shuttles such as described in which filter
boxes (D) provided with sieves (E) are inserted in the series of pipes A in order
to catch by means of said sieves any impurities, pieces of thread, dust or the like
which are drawn into the pipe and to not allow them to pass into the suction
apparatus (B) substantially as herein before described.
