COMPLETE SPECIFICATION.
Improved Apparatus for Threading Weavers' Shuttles.
I, NEWNHAM BROWNE, of 73 Cheapside in the City of London, Chartered
Patent Agent do hereby declare the nature of this invention and in what manner
the same is to be performed which has been communicated to me from abroad by
Edward Wagner, of Lodz, in the Empire of Russia, Engineer, to be particularly
described and ascertained in and by the following statement :-
This apparatus which I designate Pneumofilos and which is shown in the
accompanying drawings obviates the necessity for sucking the thread through the
appropriate opening of a weavers shuttle by the action of the operators lungs, and
my invention thus protects the weavers using it against lung-disease acquired in
this manner, and also prevents the transmission of infectious diseases by the same
means.
A special feature of this apparatus is its easy applicability, its use does not
require to be learned by the workman and therefore its adoption does not necessitate
loss of time it needs no practice to acquire facility in its use and it is therefore
equally available for the old hand and the apprentice.
In the accompanying sheet of drawings
Fig. 1, is a transverse sectional elevation of my apparatus in the position it
occupies when ready to operate, and with the shuttle to be threaded placed on it,
Fig. 2, is a longitudinal sectional elevation showing the piston depressed and the
thread drawn through.
The construction is very simple, it comprises a cylinder A, preferably of thin or
sheet metal, with its top B, fixed to the weavers bench or loom-table C. The
lower end of the cylinder has a lid, preferably of the like material, with an
aperture for the air to pass through. In the interior of the cylinder there is a
piston D, to which is attached the tube F with the lateral apertures g. On the
upper end of the tube F, extending outwards, is a sheet-metal box H, which serves
to guide the shuttle so that it will readily, and without trouble to the operator,
present its aperture to the aperture of the suction tube F. For the purpose of
obtaining a better connection the opening of the box is padded as shown at I.
A spring K acts on the piston to keep it normally raised and ready for use.
The apparatus is used as follows: Take the shuttle with the spool therein, place
the thread to the aperture o, put the side of the shuttle against the guide-box so as
to fit it to the aperture of and rapidly depress the piston. This, producing &
vacuum in the upper part of the cylinder, causes air to flow rapidly through the
tube F and the aperture g, and thereby draws the thread through.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed as communicated to me by my
foreign correspondent I declare that what I claim is :-
(1.) The improved apparatus for threading weavers shuttles whereby the
necessity of drawing the thread through by means of the operators lungs is
obviated substantially as herein before described.
(2.) An apparatus for drawing through the thread in a weavers shuttle
comprising an air chamber A, a piston D, a suction tube F, guide box H, padding I,
and spring K, substantially as described and shown in the drawings.
Dated the Third of September 1896.
