COMPLETE SPECIFICATION.
Suction Apparatus for Withdrawing Thread Ends from Weaving
Shuttles.
I, HENRY GARDNER of 166 Fleet Street, in the city of London, Patent Agent
do hereby declare the nature of this invention which has been communicated to me
from abroad by Florian von Grubinski of Warsaw, Russia, and in what manner
the same is to be performed, to be particularly described and ascertained in and by the
following statement :-
According to existing practices the spool thread of a weaver's shuttle is drawn
through the very narrow exit hole in the shuttles, by the weaver sticking his point or

page_text: needle into the spool thread in the exit hole and then by sucking it with his mouth
completely draws the thread through the exit hole of the shuttle.
This method has the great objection, that the weaver in sucking the thread, draws
the very fine dust which during work has accumulated near the exit hole of the
shuttle, not only into his mouth, but the great part of it becomes lodged in his lungs.
It follows that this method is extremely injurious to health. To remedy this evil an
apparatus is specially constructed for the purpose, the apparatus is a kind of elastic
ball, which allows itself to be drawn or compressed and automatically swelling or
expanding again to suck air into itself.
The accompanying drawings show two modifications of the apparatus for the purpose
above mentioned, according to Figures 1 and 2 it consists of a reservoir A having
mouth or opening through a pipe y provided at its outer part with an india rubber
ring or short tube h which reaches beyond and overhangs it.
The reservoir A is composed of a cylindrical part a of metal and sides b, b, of soft
leather bound thereto by means of the ring or fluted plates e, c. The middle parts of
the said leather covers b, b, are strengthened with sheet metal discs d, d. A spiral
spring e fitted in the interior presses the sides bb away from each other as indicated
at Figure 1. Upon the cylindrical portion a is a handle, to which a string may be
attached so that the weaver can hang the apparatus round his neck or over his shoulder
from his waist or otherwise.
When the sides b b of the reservoir are forced together the spring being compressed
causes the air in the reservoir A to be forced out, the rubber nozzle is then pressed
over the hole K in the shuttle shown at Figure 3, and as soon as pressure is removed
the sides will, by the expansive action of the spring e be forced apart and by this
means air will be sucked into the reservoir A, the end of the thread coming through
it. The end of the tube is stuck into the hole K of the shuttle so that the thread i is
drawn completely through the said hole K.
The apparatus is applied to the shuttle by the pressure of the palm of the hand
against the ring f, the sides bb being compressed together by the thumb and other
fingers.
In Figure 4 I show a modification of the apparatus in which the reservoir A
consists of stiff sheet metal portion a and a flexible compressible side b. On the sheet
metal part a is the knob f for the purpose of pressing the apparatus into position on
the shuttle. In other respects, the construction, the application and mode of using is
the same as in the case of Figures 1 and 2.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed I declare that what I claim is :-
1. The apparatus shown on the annexed drawings Figures 1 and 2 and its employ-
ment for drawing the spool thread through the opening in a shuttle by suction as
described.
2. I also claim the apparatus shown at Figure 4 consisting of rigid portion a and
an elastic compressible part & forming a reservoir with handle and mouth tube with
india rubber ring as set forth.
