Improvements in Smallware Shuttles.
We THOMAS COOPER of 60 Belle Vue Street, West Gorton near Manchester.
Pattern Maker and WILLIAM TEW of 64 Belle Vue Street in the same place, Engineer
do hereby declare the nature of our said invention to be as follows:-
The object of this invention is to so construct a shuttle for a smallware loom that it
shall contain and carry more weft or thread than heretofore and wh ch weft is drawn
off the pin or bobbin in a more direct line and in a less frictional manner than
hitherto.
Our improvements further relate to the means of creating and regulating the
necessary drag upon the contents of the bobbin, with facility for automatically reducing
the drag as the bobbin of weft decreases in diameter.
In performing our invention we employ a shuttle in which the bobbin provided with
wide flanges is mounted upon a vertical axis or transversely to the direction in which
the shuttle reciprocates in the loom. This permits the weft or thread to be carried
more directly to the eye of the shuttle and saves the awkward angles through which
the weft has passed hitherto in drawing off a long narrow shuttle. The eye in this
case is supported in a metal bridge piece extending from one end of the shuttle to the
other.
The improved drag mechanism consists of a pair of lever arms, one mounted on the
base of the shuttle, and carrying a spiral spring capable of being adjusted in tension―
to the greatest nicety by means of a screw and nut secured in position by a lock nut,
and the other arm mounted in the opposite side of the shuttle and being arranged to
be pressed against the weft carried by the bobbin by the extremity of the first mentioned
lever pushing against its side.
In some cases we provide the necessary drag by a clip arranged to press upon the
flange of the bobbin under the influence of a spiral spring and which is adjusted in
tension by an adjustable screw.

Improvements in Smallware Shuttles.
We THOMAS COOPER of 66, Belle Vue Street, West Gorton, near Manchester,
Pattern Maker and WILLIAM TEW of 64 Belle Vue Street in the same place, Engineer,
do hereby declare the nature of our invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
The object of this invention is to so construct a shuttle for a smallware loom that
it shall contain and carry more weft or thread than heretofore and which weft is drawn
off the pin or bobbin in a more direct line and in a less frictional manner than
hitherto.
Our Improvements further relate to the means of creating and regulating the
necessary drag upon the contents of the bobbin with facility for automatically reducing
the drag as the bobbin of weft decreases in diameter.
On the accompanying drawing Fig. 1 is a plan view (partly in section). Fig. 2
an inverted plan view and Fig. 3 a front view of a smallware loom shuttle embracing
our improvements.

page_text: In all the views a is the shuttle body constructed of wood and provided with a
metal bridge piece extending from one side to the other and forming a support for
the eve c.
This arrangement permits more space for the bobbin d which is of larger
carrying capacity than hitherto being provided with wide flanges. It is mounted
upon a vertical pin or axis d' rising from a bracket and is thus arranged trans-
versely to the direction in which the shuttles reciprocates in the loom. With this
position of the bobbin the weft or thread is carried more directly to the eye of the
shuttle and thus saves the awkward angles through which the weft has passed hitherto
in drawing off a long narrow shuttle. The eye in this case is supported in a metal-
bridge piece extending from one side to the other as illustrated.
The improved drag mechanism consists of a pair of lever arms,-one marked e
mounted on the base of the shuttle, and carrying a spiral spring capable of being
adjusted in tension to the greatest nicety by means of a set screw g and nut h secured
in position by a lock nut i and the other arm marked i mounted in the opposite side of
the shuttle and being arranged to be pressed against the weft carried by the bobbin d
by the extremity of the first mentioned lever pushing against its side as illustrated.
In some cases and as illustrated by transverse section in Fig. 4 and plan view
Fig, we provide the necessary drag by a clip k arranged to press upon the flange of
the bobbin under the influence of a spiral spring 7 and which is adjusted in tension by
an adjustable screw m or sleeve piece fixed in position by a lock nut or by a set screw
as illustrated. This clip is capable of being drawn back to release the bobbin by
pressure exercised upon the thumb piece.
Having thus particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is -
1st. The improved construction and arrangement of smallware loom shuttle sub-
stantially as herein described.
2nd. In a smallware loom shuttle mounting the bobbin upon a vertical axis sub-
stantially as and for the purposes herein before described.
3rd. The improved construction of drag mechanism substantially as hereinbefore
described and illustrated on the accompanying drawing.
