PROVISIONAL SPECIFICATION.
Improvements in and relating to Loom Shuttles.
We, WILLIAM SARGENTSON, of Glenthorne, Padfield, Waste Dealer, and
JAMES GILBERT, of Railway Street, Spinner, both of Hadfield in the County of
Derby, do hereby declare the nature of this invention to be as follows:-
This invention relates to shuttles for use in looms and its object is to provide
means whereby such shuttles may be more easily threaded than at present without
their efficiency being affected when in use.
In carrying this invention into practice a slot or groove is formed in the body
of the shuttle extending from the open part towards the tip and a second slot or
groove is formed which extends from the first and passes obliquely over the shuttle
and terminates at the delivery point.
Within this slot is placed a wire which is suitably bent and coiled so as to form
two eyes or thread guides one of which is at the junction of the grooves and the
other at the delivery point. The threading is accomplished by laying the thread
within the first groove and pulling it sideways and down' into the second slot
by which action the thread is passed into the two guides or eyes formed in the
wire.
The delivery guide is so formed that although the thread enters. with the
greatest facility it cannot possibly be withdrawn by the usual working of the
shuttle.

COMPLETE SPECIFICATION.
Improvements in and relating to Loom Shuttles.
We, WILLIAM SARGENTSON of Glenthorne, Padfield, Hadfield, in the County
of Derby, Waste Dealer, and JAMES GILBERT, of Railway Street also of
Hadfield, Spinner, 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 shuttles for use in looms and its object is to provide
means whereby such shuttles may be more easily threaded than at present without
their efficiency being affected when in use and without suction.
In carrying this invention into practice a slot or groove is formed in that part
of the shuttle extending from the open part towards the tip, and a second slot or
groove is formed which extends from the first and passes obliquely over the shuttle
and terminates at the delivery point.
Within this slot there is placed a wire suitably bent and coiled so as to form
two eyes or thread guides, one of which is at the junction of the grooves and the
other at the delivery point. Or, in substitution for the bent and coiled wire, an
equivalent plate and thread guide may be employed, an eye or thread guide being
formed in the plate in place of the eye which in the case of the wire is at the
junction of the slots..
We will more particularly describe our said invention with reference to the
accompanying drawings, in which
Figure 1 shews a perspective view of a front part of a shuttle having our
improved threading device applied thereto.
Figure 2 is a sectional elevation of the same, and

Figure 4 is a side elevation and Figure 5 a plan of the threading device detached
from the shuttle.
Figure 6 is a partial perspective view corresponding with Figure 1, with the
plate substituted for part of the wire device therein shewn.
Figure 7 is a vertical section of Figure 6, and
Figure 8 is an inverted section shewing the shuttle ready for the reception of
the device.
Figure 9 is a side elevation of the plate, and
Figure 10 a plan including the thread guide which is not shewn in Figure 9.
In each of the figures in which the parts are represented, A is the body of the
shuttle, C the tongue, D the cop thereon.
In the form of the threading device illustrated in and by Figures 1 to 5
inclusive, a suitable length of brass or steel wire is screwed at one end and bent
to the form shewn by Figures 4 and 5, and so as to produce the two eyes or thread
guides E E, of which E will come at the junction of the before mentioned slots,
and E' at the point of delivery in the side of the shuttle. The longitudinal slot F
is formed from the hollow of the shuttle to a point near the tip, and the diagonal
slot G connects the point of delivery with the longitudinal slot as shewn by
Figures 1 and 6. This slot is also shewn in Figures 3 and 8 at its junction with
the longitudinal slot. At the delivery point a hole is bored for the reception of
the thread guide E¹ which lies flush with the side of the shuttle.
In order to enable the threading device illustrated by Figures 4 and 5 to be
fitted to the shuttle, two additional temporary slots K K' are made. Of these,
the slot K' is made in the bottom of the shuttle for the passage of the screwed
end of the device, and K in the side of the shuttle, for the passage of the thread
guide. The device is applied as illustrated by Figure 3, where its first position is
shewn by the full lines. From this position the device is pushed along the slots
towards the tip of the shuttle until it finally occupies the position shewn by the
dotted lines. The side slot K so far as it is unoccupied by the thread guide is
then filled up. At the outer part of the portion of the slot K' which is finally
occupied by the end of the screwed stem, a recess is formed for its nut H. Å
collar or nut I is also arranged on the screwed part to act as a stop.
To thread the shuttle, the end of the weft from the cop is taken between the
finger and thumb, passed along the longitudinal slot F, returned around the point B
of the device,-passed-into-and-down-the-diagonal-slot-G-by-which-the-thread-is-
brought down and into the thread guide E. The weft is now outside the eye at
the delivery point, and in order to make it enter this eye E¹ it is only necessary
to pass the weft around it until it enters, the eye being constructed similarly to
the well known pig-tail thread guide, but flatter, as shewn. It will be understood
that for the purpose of enabling the weft to enter the eye E¹ there must be a little
clearance around it for the movement of the yarn.
The modification of the device represented by Figures 6 to 10 inclusive has been
designed to obviate the necessity for the temporary slots and to secure greater.
strength. With the exception of the temporary slots K K' the slots for the device
are the same as those already described. The eye E is formed in the plate P and
a slit connects this eye with the point B. The eye E' is formed in a separate
piece of wire the inner end of which is turned up so as to engage with the plate P
and prevent its withdrawal so long as the plate is in position. The eye E is
rounded to prevent its cutting the weft, and there may be a shallow groove formed
in the plate leading from the direction of the nose of the cop up to the eye, for
the weft to travel along.
The screwed stem may be in the position indicated by the drawings, or at or
nearer to the end of the plate next to the cop, in which case that part or some
part of the plate under the slit connecting its eye with the point B may be
removed.

page_text: The method of connecting the device with the shuttle is illustrated by the
Figure 7. First, the separate piece of wire in which the eye E¹ is formed is
inserted as shewn, with its returned end pointing upwards. The nut H having
been removed, the plate is brought into the position indicated by the dotted lines
and is then dropped into the slot F. A hole and recess being provided for the
screw and nut H the device is made fast by screwing up the nut on the stem.
The shuttle is threaded precisely as described with reference to the wire device.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is-
'
1. A shuttle threading device consisting of a longitudinal and diagonal slot F G
two thread guides or eyes situated at the junction of the slots and at the delivery
point respectively, and a bent wire or equivalent plate in the longitudinal. slot
around the point of which the weft is passed threading the shuttle, substantially as
described and as illustrated by the accompanying drawings.
2. A threading device for loom shuttles, constructed arranged and operated
substantially as hereinbefore described and as illustrated by the accompanying
drawings.
