PROVISIONAL SPECIFICATION.
Improvements in Shuttles for Weaving.
We WILLIAM KNIGHT of Edenfield Road, and ROBERT ASHWORTH of Butterworth
Terrace both in Norden Rochdale in the County of Lancaster Managers, do hereby
declare the nature of this invention to be as follows:-
These improvements are principally applicable for weaving fustians in looms
wherein there is no positive taking-up motion, but they may also be employed in
weaving other kinds of fabric wherein it is required to lay two weft picks in the same
"shed of the warp.
The object of the invention is to enable the weaver to put the two weft threads in
the same shed at one pick, and with only one beat up of the lathe, whereby a great
saving in time and labor is effected.
For this purpose we make the shuttle nearly twice the ordinary length with a solid
partition in the centre, and this shuttle we provide with two tongues of the ordinary
construction, the same being preferably so arranged that their points nearly touch the
central partition.
There is a hole through the latter and the threads from the two cops (one on each
tongue) pass out, one through the side and one through the bottom of the central part
of the shuttle through two of the ordinary "pot" eyes.
By these means at every pick of the shuttle across the loom it lays two weft threads
in the "shed" of the warp, which are both beaten up together by one beat of the
lathe.
In some cases we propose to make the shuttle of about double width so that the two
cops may be arranged side by side in which case the lathe and shuttle boxes would
have to be made wider to correspond therewith, but for most purposes we prefer to
increase the length of the shuttle so that the two cops lie point to point as first above
described.

COMPLETE SPECIFICATION.
Improvements in Shuttles for Weaving.
We WILLIAM KNIGHT of Edenfield Road and ROBERT ASHWORTH of Butterworth
Terrace both in Norden, Rochdale, in the County of Lancaster Managers do hereby
declare the nature of this invention and in what manner the same is to he
performed, to be particularly described and ascertained in and by the following
statement:
Our invention relates to improvements in shuttles for weaving, which are chiefly
applicable for weaving fustians in looms wherein there is no positive taking up
motion, but they may likewise be employed in weaving other kinds of fabric wherein
it is required to lay two weft picks in the same shed of the warp.
The object of our invention is to enable the weaver to put the two weft threads in
the same shed at one pick, and with only one beat up of the lathe, whereby a great
saving in time and labor is effected. For this purpose we make the shuttle twice the
ordinary length or thereabout, and we provide the same, with a solid partition in the
centre, and with two tongues of ordinary construction arranged preferably in such a
manner that their points nearly touch the central partition aforesaid. An opening is
formed in the latter through which pass the threads from the two cops (one on each

side and the other in the central part of the underside of the said shuttle.
By these means at every pick of the shuttle across the loom, it lays two weft
threads. in the shed" of the warp, which are both beaten up together at one heat of
the lathe.
In some cases, we may double the width of the shuttle, so that the two cops may be
arranged side by side in which case the lathe and shuttle boxes will likewise have to
be made wider to correspond therewith, but for most purposes.however, we prefer to
increase the length of the shuttle, so that the two cops may be point to point as first
described.
And in order that our invention may be more fully understood, we have shewn the
same in the accompanying drawings, in which
Fig. 1 is a plan, Fig. 2 a longitudinal section, Fig. 3 a cross section and Fig. 4 a
side view of our improved double shuttle.
S is the shuttle furnished with a central partition p, furnished with an opening
formed in the centre thereof. This partition divides the shuttle in two parts, each of
which is provided with a tonguet of ordinary construction hinged at h h near each
extremity of the shuttle S, their points being as clearly shown in Fig. 2 in close
proximity to the partition p. The threads proceeding from the two cops (not shown
in the drawing.) pass respectively through the two "pot" eyes a and a¹, è e¹ are two
cross pins used for strengthening purposes.
e
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The improved shuttle for weaving purposes arranged and constructed substantially
as herein described and shewn in the accompanying drawings, and for the purpose
set forth.
