Threading the Shuttles.
I, ELI DYSON, of Vickers Street, Miles Platting, Manchester, in the County of
Lancaster, Manager of Chemical Works, do hereby declare the nature of this
invention to be as follows:-
The operation of threading the yarn through the eyes of shuttles for use in looms
for weaving is largely performed by the operative by suction of the mouth. This is
very objectionable as dust from the yarn is at the same time inhaled which in the
case of dyed yarns especially, proves injurious.
The object of this invention is to provide an apparatus by which the yarn will be
threaded through the shuttle eye without the necessity of the operative "putting the
shuttle to the mouth.
A slide or receptacle is provided to the frame of the loom or placed in other suitable
position to receive the shuttle. In proximity to this slide is placed a device made of
indiarubber, leather or other suitable material by which a gentle suction can be
produced. Leading from this device is a hole or passage controlled by a valve against
which the eye of the shuttle is brought and by the suction created the end of the
yarn is drawn through. The apparatus may be worked by hand or power a gentle
reciprocating, longitudinal, or rotary motion causing the apparatus to be alternately
compressed or expanded the required suction being thereby created. Instead of
creating the suction by compressing or inflating a chamber, a fan or similar apparatus
may be used for the purpose but I do not at present prefer it.
The apparatus will be best made as a fixture to the frame of the loom or other
suitable structure though it may be made portable if desired.

Improved Apparatus for Use in Connection with Looms for
Threading the Shuttles.
I, ELI DYSON, of Vickers Street, Miles Platting, Manchester, in the County of
Lancaster, Manager of Chemical Works, 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 operation of threading the yarn through the eyes of shuttles for use in looms
for weaving is largely perforined by the operative by suction of the mouth. This is
very objectionable as dust from the yarn is at the same time inhaled which in the
case of dyed yarns especially, proves injurious.
The object of this invention is to provide an apparatus by which the yarn will be
drawn through the shuttle eye' without the necessity of the operative putting the
shuttle to the mouth.
It consists essentially of a small chamber or cylinder fitted with. a diaphragm,
piston, fan or equivalent by means of which a suction or current of air can be
produced and fitted to, or used in connection with a loom for the purpose of drawing
the ends of thread or yarn through the shuttle eye.
The invention will be fully understood by reference to the accompanying
drawings.
Fig. 1 is a sectional elevation of apparatus constructed according to my invention.
Fig. 2. Front elevation of same.
Attached to the frame A of the loom or in other suitable position in proximity to
it is a chamber B fitted with a diaphragm D or its equivalent. The chamber B is
preferably of the shape shown and the diaphragm D formed of a cup shaped india-
rubber to fit into it. The casing of the chamber B terminates at one end in a nozzle
fitted with a trumpet or flaring end E through which runs a hole or opening into the
chamber. The flaring end E is fitted with a pad of indiarubber F, or other soft
material against which the shuttle is placed with the eye over the hole. The indiarubber"
pad F, acts as the seating or packing of a valve when the shuttle is pressed against
it to prevent escape of air around the shuttle eye. At the other end the chamber B
is enclosed with a plate or cover G through which a few air holes g are bored. To
the diaphragm or cupped indiarubber D is attached a spindle or rod H projecting
through the plate or cover G. By drawing out the spindle H the diaphragm or cupped
indiarubber. Dis drawn forward and the space occupied by it being filled with air an
inward draught or suction through the hole fis'created. The diaphragm D is returned
to its position by the spring 1. As shown, the spindle H is intended to be drawn out
by hand and moved back by the spring I but instead it may be worked by a small
crank receiving motion from some part of the loom.
It will be evident that the chamber B instead of being bell shaped may be made
cylindrical or of other suitable shape and the diaphragm may be displaced by a piston,
or a small fan may be placed in the chamber which would produce a continuous
suction.

The apparatus will be best made as a fixture to the frame of the loom or other
suitable structure though it may be made portable if desired.
'
In operation the yarn will be laid loosely against the eye of the shuttle on one
side and the eye on the outside brought opposite the hole f in the nozzle E. The
spindle or rod H is pulled out with a quick movement which by the suction
created by the movement of the diaphragm draws the end of the yarn through
the eye.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I wish it to be understood
that what I claim is :--
1. The combination or use with a loom of a suction apparatus for threading shuttles
substantially as described.
2. An apparatus for threading shuttles having a diaphragm piston, or fan or their
equivalent fitted in a chamber to create a suction to draw the thread through the
eyes of shuttles substantially as described.
3. In an apparatus for threading shuttles, the combination of the cup shaped
chamber B the indiarubber D the nozzle E and pad F substantially as and for the
purpose described.
