COMPLETE SPECIFICATION.
Improved Means Applicable to Looms for Threading Shuttles.
I, JEAN BOURRY, of Müllerhof Urmatt, Alsace, in the German Empire,
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:-
This invention relates to a device applicable to looms for withdrawing from the
shuttle the end of the shuttle-thread.
It is a well-known fact that the usual practice of simply applying the mouth to
the shuttle to be "started," and thereby sucking the end of the thread out of the
shuttle, is most inconvenient, and moreover injurious to the health of the operatives,
because, together with the thread, any dust or impurities which may have collected
in the shuttle are drawn into the mouth, and thence reach the respiratory organs,
which they harmfully affect.
The object of the present invention is to avoid such inconvenience and danger
by providing mechanism for drawing the end of the thread out of the shuttle.
The accompanying drawing represents in longitudinal section a device constructed
in accordance with the present invention.
The improved device comprises a cylinder A, attached to the loom by any
suitable means, such as the thumb-screw a and the projection a', shown in dotted
lines. Working in the cylinder A, there is a piston or plunger B, operated by a
lever C, which is pivoted to an arm a³, projecting from the cylinder A, and jointed
to the plunger B by a forked link D. The cylinder A is open at its lower end,
while at the top it is closed by a lid or cover E concave on the under side and
having a small central perforation e. Over the lid E is secured a disc or washer F
of flexible material, preferably india-rubber, which contains in the centre a
comparatively large perforation f
The action of the parts is as follows:-
The operative first inserts with one hand the point g of the shuttle G into
the eye as formed in an arın a' projecting upwardly from the cylinder A, and at the
same time firmly presses the shuttle upon the india-rubber washer F, so that the
orifice or passage H leading from the shuttle-eye coincides with the perforation f.
The shuttle lies between a pair of guiding cheeks, one of which (a) is shown in
dotted lines. These cheeks project from the cylinder A. The operative, with his
other hand, then quickly depresses the lever C, whereby the plunger B is caused
to descend and suck the free end of the thread J out of the eye of the shuttle and
through the passage H, the washer F and the lid E into the cylinder A.
Having thus particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I claim :-
1. For threading loom-shuttles, a device arranged or operating substantially as
berein described.
2. For withdrawing from a loom-shuttle the end of the shuttle-thread, the herein-
described device comprising a cylinder with a perforated lid and washer, and a
plunger working in the cylinder and adapted when suddenly depressed to suck the
end of the thread out of the eye of the shuttle.
Dated the 24th day of August 1893.
