do hereby declare the nature of this invention to be as follows;-
-
This invention relates to an improvement in shuttles for embroidering machines
and the like.
In shuttles hitherto used with this class of machinery (as is well known) the
bobbins are usually inserted by hand in the shuttles, and the thread, after it has
been passed under the cover spring, is inserted through the wall of the shuttle
by the same means.
The invention on which Letters Patent are now sought comprises a device for
passing the end of the thread from the bobbin in the shuttle, and inserted under
the cover spring, automatically through the side wall of the shuttle, For this
purpose there is provided in place of the usual round thread hole a slot or length-
ened opening in the shuttle wall, which admits of the passage of a hook, which-
hook can take firm hold of the end of the thread, and draw it through the wall
of the shuttle.
In the accompanying drawing a constructional form of the shuttle provided
with the thread hole in the form of a slot is shewn.

Figure 2 a plan view of the shuttle, which also is designed to shew clearly the
cover.

A communication by STICKEREI FELDMÜHLE VORMALS LOEB, SCHOENFELD & Co.,
of Rorschach, in the Republic of Switzerland.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both
in the County of Lancaster, 118, New Street, Birmingham, in the County of
Warwick and 322, High Holborn, in the County of Middlesex, Civil Engineer,
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 follow-
ing statement:-
This invention relates to an improvement in shuttles for embroidering machines
and the like.
In shuttles hitherto used with this class of machinery (as is well known) the
bobbins are usually inserted by hand in the shuttles, and the thread, after it has
been passed under the cover spring, is inserted through the wall of the shuttle
by the same means.
The invention on which Letters Patent are now sought comprises a device for
passing the end of the thread from the bobbin in the shuttle, and inserted under
the cover spring, automatically through the side wall of the shuttle. For this
purpose there is provided in place of the usual round thread hole a slot or length-
ened opening in the shuttle wall, which admits of the passage of a hook, which
hook can take firm hold of the end of the thread, and draw it through the wall
of the shuttle.
In the drawing accompanying the Provisional Specification, a constructional
form of the shuttle provided with the thread hole in the form of a slot is shown.
Figure 1 is an elevation; and
Figure 2, a plan view of the shuttle, which also is designed to show clearly the
cover.
The
The shuttle a is provided with a cover c hinged on the axle b, and below which
the so-called shuttle bobbin is placed. In the cover c is formed the aperture co
through which passes the thread d as it is unwound from the bobbin.
thread d is devised to pass through the shuttle wall after it has been passed under
the spring e. The shuttle wall is provided with a slotted opening f, serving as the
thread hole. The slotted form facilitates the entrance of a hook, which can
seize the thread d at the point of the cut-out piece of the cover c¹ and draw it
through the slotted opening f.
By means of the above described longitudinal or slotted form of thread hole,
in which the direction of the slot is planned to be as far as possible perpendicular
to the track of the shuttle, the hook can enter from below upwards through the
aperture c¹ and can draw the thread downwards, and through the slot f.
The essential feature of the invention consists in the thread hole being formed
as a slot in the vertical wall of the shuttle and perpendicular to or approximately
perpendicular to, the direction or track of the shuttle.

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to
me by my foreign correspondents, I declare that what I claim is:-
1
An improved shuttle for embroidery machines, characterised by the thread
hole being formed as a slot in the vertical wall of the shuttle and perpendicular
to, or approximately perpendicular to, the direction or track of the shuttle,
with the object of allowing an automatically moved hook coming sideways from
below to reach the cover of the shuttle and there to securely grip the end of the
thread and draw it through the wall of the shuttle in order to thereby render
the shuttle ready for use for the embroidery in an automatic manner substan-
tially as described.
