Improvements in Shuttles for Weaving.
I ALBERT ABEGG of Weinbergstrasse 15 Zurich Switzerland, Mill Furnisher,
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 the shuttles used in looms for weaving and especially to
the porcelain or earthenware eyes or eyelets thereof through which the weft thread
passes the principal object of the improvements being to enable a greater or less
tension, to be exerted upon the weft in passing through the same so as to increase
or diminish the tightness of the thread, as may be required.
The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference
to the annexed sheet of illustrative drawings and the following explanation
thereof.
Fig. 1 on the drawings is a partial sectional plan view of one end of a loom
shuttle, shewing also in section the application thereto of my improved eyelet.
Fig. 2 is a similar view shewing the eyelet in elevation.
Figs. 3 and 4 are views of the respective sides of the shuttle Fig. 3 showing the
"reed" side and Fig. 4 the side through which the weft thread passes.
Figs. 5 and 6 are similar views of a modification of the same.
Referring to Figs. 1, 2, 3, 4, the shuttle is bored straight through, a is an eyelet
consisting of a cylindrical or conical piece of porcelain earthenware or other
suitable material, bored only partly through as plainly shown at Fig. 1. It is made
with a shoulder at +
so that when passed in from the right hand it cannot penetrate
beyond the point shown.
It is held in place by means of a metallic screw c, an india rubber or other
washerd being interposed between the two surfaces.
The eyelet a is provided with a hole b at right angles through which the weft
thread from the cop passes into the eyelet.
In Fig. 1 this hole 6 is shown in such a position that the weft thread passes in a
direct line from the cop into the eyelet and in this position the tension upon the
weft thread is at the minimum, but by loosening the screw c and turning the
eyelet a partly round so that the hole is brought into a vertical position as shown
at Fig. 2 a greater amount of tension will be put upon the thread, and if desired a
still greater amount of tension may be put onto the weft thread by turning the
eyelet round still further. When the required position of the hole has been
adjusted the eyelet is fixed by tightening the screw c.
In the modification shown at Figs. 5 and 6 the shuttle is only partially bored
through, the metallic screw c is made hollow or tubular and is applied to the
delivery side of the eyelet.
In another modification of which I have not thought it necessary to show a
drawing the exterior of the porcelain or earthenware eyelet a is made slightly
conical, the shuttle being bored to correspond, in which case the shoulder
may be
dispensed with, and for the cheaper class of shuttles the screw c may also be
dispensed with, the eyelet a being simply kept in its place by forcing it tight into
the conical hole in the shuttle.
A further improvement in the shuttle consists in cementing to the "reed" side
thereof a thin slab or strip of the composition known as "vulcanized fibre." This
slab or strip may be let in "flush" and is glued or otherwise attached to the wood.
This material takes a high polish and diminishes the friction of the shuttle in
passing the reed and being of a harder nature than the wood it considerably.

weight of the same.
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 :-
First. The improvement in shuttles for looms consisting in the combination
therewith of a porcelain or earthenware eyelet (either cylindrical or conical) bored
partly through and having a hole at right angles, so that the same can be turned
partially round so as to increase or decrease the tension on the weft thread
substantially as herein before described and illustrated by the drawings annexed, and
Secondly. I claim the improvement in shuttles for looms consisting in the
protection of the "reed" side thereof by a thin strip or slab of the composition known
as "vulcanized fibre" glued or otherwise cemented thereto substantially as and for
the purposes herein before set forth.
