This invention relates to improvements in loom shuttles.
In the accompanying drawing,
Fig. 1, is a plan view of a shuttle, supplied with the improvement.
Fig. 2, is a cross sectional view of the same, taken at the point indicated by the
dotted line x, a, on Fig. 1.
Fig. 3. is a view in perspective of the device, removed from the shuttle body,
showing the thread in the act of passing into the eye.
Fig. 4, is a sectional view, taken in the plane indicated by the dotted line y, y,
on Fig. 3.
Referring by letter to said drawings, A. indicates the shuttle body, and B. the

provided in one of its side walls near its forward end, with an orifice a, and the
bottom or floor of said body is pitched slightly towards the orifice, shown at b, for
the purpose of seating the device, as will be presently described. C, represents
the threading device. This device may be formed of metal or other suitable
material, and for the sake of cheapness and durability, is formed from a single
piece, comprising a base c, having apertures d, for the reception of screws or other
suitable devices, whereby the whole may be secured in the body of the shuttle.
Rising from the base, is a post or upright e, upon which is formed a cam shaped
plate f, which in practice, extends inwardly and forwardly, within the shuttle
body.
Rising from the base, on the outer side of the cam shaped plate f, is a guide
post g, which is designed to guide the thread into the eye h, which is exposed
through the orifice a, of the shuttle. The threading device or casting C, is further
provided with a recess i, which is also designed to be exposed through the orifice
of the shuttle body, so as to permit the partial insertion of the operative finger, to

formed at the base of the guide post g, and partly within the cam or guide flange,
at the base of the plate f.
D. indicates a vertical flange, which is arranged on the inner side of the casting,
between the base and cam plate, for a purpose which will be presently described.
In connection with the threading device, we have provided a means for removing
kinks and detecting knots in the thread. This device comprises a clamp E, which
is placed upon the flange D, and carries an upwardly curved branch k, which may
be formed of wire or other suitable material, and which is designed to touch or
nearly touch at its free end, and at the under side of the plate f, and two shorter
arms or branches 1, which are directed downwardly and may touch the base plate,
so as to present a flairing entrance for the passage of the thread between the
respective arms or branches as better shown in Figs. 2, and 4, of the drawings.
In placing the improvement upon old shuttles, it is simply necessary to cut an
orifice a, in one side, and bevel the bottom, as shown at b, and in a plane with
the bobbin; while with new shuttles, they may be so constructed in the
manufacture.
After the body has thus been formed, the casting should be placed so that the
eye, the guide post g, and also the aperture or recess i, will be exposed through

page_text: the orifice a; when the base plate may be secured by screws, or other suitable
fastening devices.
To thread the shuttle, the thread should be taken from the bobbin, and a loop
formed, after which, it should be placed over the cam plate f, or loop taker, as it
may be termed, and drawn, until said loop is guided by the beveled edge, or cam
surface m, of said plate aided by the guide post g, down to the eye h. In this
position, the thread will be exposed through the orifice a, and also in the recess i,
when by simply inserting the finger of the other hand into said orifice, the free end
of the thread will be drawn out of the shuttle, through the recess i, and orifice a,
where it will be properly held in the eye, ready for use.
While we have described the plate, as being cam shaped, yet it is only
necessary that it should be so constructed, as to receive a loop from the bobbin,
and have a bevel, such as m, to guide the loop down into the eye, and we therefore
do not wish to be understood as confining ourselves to the exact form of loop
taker, which we have shown and described. A device of the character may be
very cheaply manufactured, and at a minimum expense, may be placed in Dew
shuttles as well as in such shuttles as are at present in use; and by reason of the
device, being placed on a pitch or incline, the drawing of the loop into the eye, is
much facilitated.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim, is―
1st. In a self threading shuttle, the combination with the body, having an orifice
in one of its side walls, of a cam shaped plate, or loop taker, arranged in the body,
and having an eye at its base, said eye being exposed through the lateral orifice of
the body and the guide post, rising from the base of the loop taker at the side of
the cam plate and the eye, and also exposed in the orifice of the body, substantially
as specified.
2nd. In a loom shuttle, the threading device comprising the base and cam plate,
and having the flange D, arranged between said base and cam plate, in combination.
with the clamp, removably secured to the said flange, and carrying the long
upwardly curved arm, and the two short downwardly curved arms, to receive
between them, the thread from the bobbin, substantially as specified.
3rd. The shuttle body, having the lateral orifice at its forward end, and also
having its base or floor inclined as described, in combination with the casting,
secured upon said inclined base and in the orifice, and having the loop taker, and
also the recess i, the vertical guide post arranged at the side of the loop taker, and
the eye at the base of the post and on the outer side of the Icop taker; said eye,
the guide post, and the recess i, being exposed in the orifice of the shuttle body,
substantially as specified.
