improvements in waving
I, IGNACY MACIEJOWSKI, of Zawiercie, District of Petrikau, Poland, Russia,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
The first of my improvements relates to the threading arrangement, and
consists in the employment, as eyelet holes of small tubes which are slit in the
direction of their length, in a right line, obliquely or spirally and are made of
any suitable material, but preferably of porcelain or earthenware.
The small tube may be entirely cylindrical, and may have outside the cylin-
drical part a flat part or flange which serves for fixing the tube into the side of
the shuttle. The tube is let into the wooden side of the shuttle, and for the
introduction of the thread, slots are formed laterally in the side of the shuttle
or all around the upper end of the tubes, such slots communicating with the
slits mentioned above, in the eyelet.
The semi-circular incisions at the lower end of the tubes serve to facilitate
the introduction of the thread into the tubes. The threading itself is quite
clear, and easy, and is effected with the hand, without the necessity of employing
the mouth.
In order to prevent the thread from accidentally falling out of the tube, the
latter is provided with a small projection the extremity of which is formed in
such a manner that it extends beyond the end of the threading slit or slot and
prevents the thread, when once inserted, from falling from the interior of the
tube into the slit.
In a modification of my invention the tube is composed of a flat, and of a
bent part and between these two parts is formed a slit. The whole arrangement
consists in a hole formed in the front end of the shuttle and connected directly
(by means of the horizontal slot in the front (or side) of the shuttle and the
slit communicating therewith), with the interior of the tube which is in the
wall (or side) of the shuttle. The thread can thus be easily introduced by means
of this hole into the interior of the tube. The drawing in of the thread is
superfluous and the threading is effected in the following manner.
After the thread has been introduced directly into the hole in the shuttle, it
is held by the thumb and finger of the one hand in the opening which leads to
the small tube, the thread being then drawn along the slit, until it reaches the
interior of the tube.
+
To prevent the accidental slipping out of the thread in this arrangement, the
projection above mentioned may be employed, or the same result can be obtained
by introducing the front point of the bent part into a hole formed in the flat
part of the tube.
Another improvement in the said shuttles consists in modifying the form of
the point of the shuttle. This modification is such that the upper surface of
the two pointed extremities of the shuttle, is not symmetrical with the lower
surface, as is usually the case, but the ratio of the curve radii of the upper and
lower surfaces gradually diminishes. In this manner, the point is no longer

page_text: half-way in the height of the shuttle, but in the first third of such height, com-
mencing from below.
The object of this modification is to prevent the shuttle from coming out of
the shed. Ordinarily, the shuttle comes out of the relay when its point is raised
by any obstacle encountered in its course, or by a broken chain or one that is
accidentally too low. The point meets the upper chains of the shed in clearing
a way for itself through these chains, and thus arrives by a powerful oscillation
above the shed. It is therefore to prevent the slipping out of the shuttle, that
the point of the same is shifted, and formed as above described.
In this manner, the shuttle cannot be raised except by imperfectly arranged
chains which are still lower than the point of the shuttle. On the other hand,
it may be raised by some other obstacle, but the upper rounded surface pre-
vents the shuttle from coming out of the shed, because the point cannot pene-
trate between the upper chains of the shed; these chains causing the shuttle to
deviate and keeping it in the shed.

I, IGNACY, MACIEJOWSKI, of Zawiercie, District of Petrikau, Poland, Russia,
Manufacturer, 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 present invention relates to improvements in weaver's shuttles..
An example representing the improvements is shewn in the accompanying
drawings.
The first of these improvements relates to the device of threading, as shewn
by Figs. 1, 1" and 1b.
Fig. 1 is a front view of the shuttle; Fig. 1 is a horizontal section on the
line of Fig. 1, and Fig. 1b, is a plan view of the same part of the shuttle.
The device consists of an aperture D in the front wall of the shuttle, which
aperture is by means of the horizontal slot f f' directly connected with the space
serving to receive the small tube B used as an eye.
The small tube B is represented in the Figures 2, 2", and 2b, shewing a plan,
a side view and a front view respectively. The flat part R serves to fix the
tube which is made by bending the material of which it consists. A slit which
communicates with the slot f f mentioned above, and through which the thread
is introduced into the tube, being formed between the curved part P and the
flat part R of the tube B.
The threading operation is effected in the following manner:-
After introducing the thread directly into the aperture D, it is held with the
thumb and finger of the other hand in the aperture K which leads to the seat
of the small tube B the thread afterwards being drawn along the slot until it
reaches the interior of the tube.
The tubes serving as eyes may be made of any material but they consist pre-
ferably of porcelain, earthenware, glass or enamelled metal.
In order to prevent any accidental slipping of the thread, the point of the
bent part Penters into the aperture t which is arranged in the flat part R, as

page_text: it is shewn in Fig. 2, the same result is obtained by the device shown in Fig. 3,
and which consists in a projection e extending beyond the extremity of the
point of the tube.
Another improvement in the said shuttles consists in modifying the form of
the point of the shuttle; this modification is of such a nature that the upper
surface of the two pointed extremities of the shuttle is not symmetric with the
lower surface, as is generally the case, but that the proportion of the radii of
curvature of the upper and lower surface decreases gradually. In this case the
point is not in the middle of the depth of the shuttle but on the level of the
first third part of this space, reckoning from below.
This modification has for its object to prevent the shuttle from leaving the
shed. As a rule the shuttle gets out of this shed when its point is raised by an
obstacle on its path, or by a broken chain or by a chain which happens to be
too high the point meets the upper chains of the shed when it makes its way
through them and it arrives thus by a strong oscillation above the shed. In
order to stop the gliding out of the shuttle the point of the latter is displaced
and given the form shewn in Fig. 1, of the annexed drawings; in this manner
the shuttle cannot be raised anymore unless by chains arranged in a defective
manner and placed still lower than the point of the shuttle. On the other hand
the said point could be raised by any other obstacle, but the rounded upper sur-
face (Fig. 1) does not allow the shuttle to leave the shed, because the point is
not able to penetrate the upper chains of the shed, these chains turning aside
the shuttle by keeping it within the shed.
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 shuttle with a threading device consisting of two apertures connected
together by a slot, one of the apertures containing a small tube serving as an
eye, which tube is provided with a lateral slit through which the thread is intro-
duced into the tube above the first aperture and the slot connecting, the two
apertures, substantially as described above.
2. A weaver's shuttle the two points of which are lower than the centre of the
shuttle, being bent back towards the bottom for the purpose set forth.
