We, WILLIAM HOLDEN, Overlooker, HENRY HOLDEN, Gentleman,
HOLDEN, Weaver, and JAMES HOLDEN, Overlooker, all of 158, Downham Street,
Blackburn, in the County of Lancaster, and JOHN THOMAS SAGER, of 140, Redlam,
Blackburn aforesaid, Clerk, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in the method of and means employed
for weaving split ups the object being to construct a split up motion which will
be efficient and inexpensive and can be applied to existing looms in a very short
time.
According to this invention we fix to the front heald staves a metal rod or
bracket to which is cast or fixed an inclined guide for effecting the requisite cross-
ing of the warp threads and having in it two vertical holes and through these holes
are passed a pair of needles or eyed wires the lower ends of which are connected
by elastics to the treadle or lamb of the back heald staves.
Two warp threads which are to form the cross shed for one side of the split up
are carried from the warp beam directly under the back rest and over the crank
shaft. One of these threads is then passed between the healds and at one side of the
back heald and at the opposite side of the front heald and then to the shed near
the cloth or piece being woven, and this thread always remains at the bottom of
the shed. the other thread is drawn through the eye in one of the healds in the
back stave, thence to and through the loop or eye of the needle in the front stave.
Each side of the split up is formed in the same manner.
The action is as follows:-When the loom is in motion, and say the back heald
stave rises, the back treadle also rises and this allows the needles to be raised by
the back healds, and the front stave is lowered and the warp end in the needle
is carried up one side of the standing warp end. When the back stave is lowered
and the front one raised, the back treadle falls and takes with it the needles,
carrying with them the warp ends so that the latter are moved to the opposite
side of the stationary warp ends and a cross shed is formed when the operation is
repeated. The inclined portion of the guide causes the warp thread to slip down
easily when required, and the tops of the needles are buried or sunk in the vertical
eyes at this time.

We, WILLIAM HOLDEN, Overlooker, HENRY HOLDEN, Gentleman, RICHARD
HOLDEN, Weaver, and JAMES HOLDEN, Overlooker, all of 158, Downham Street,
Blackburn, in the County of Lancaster, and JOHN THOMAS SAGER, of 140, Redlam,
Blackburn aforesaid, Clerk, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to improvements in the method of and means employed
for weaving split ups, the object being to construct a split up motion which will
be efficient and inexpensive and can be applied to existing looms in a very short
time. The invention consists of a light metal rod or frame fixed to the front heald
staves and to which rod is cast or fixed an inclined guide having in it two vertical
holes through which are passed a pair of needles the lower ends of which are con-
nected by elastics to the treadle or lamb of the back heald staves. One of the
two warp threads which are to form the cross shed is passed between the healds,
and the other is passed through an
eye" or male" in the back heald and thence
through a loop or eye of one of the needles in the front stave. One thread is
always at the bottom of the "
shed""*
eye of the needle form the requisite. "cross" for the split up. The apparatus, is
and this and the one passing through the
less expensive than the chains heretofore commonly used and produces a better
shed.

Such being the nature and object of our said invention, the following is a com-
plete description of same, reference being had to the accompanying drawings, in
which:
Fig. 1 is a front elevation of the improved apparatus for weaving "split ups."
Fig. 2 is a like view of a modified form of the improved apparatus.
Fig. 3 is a sectional plan view drawn to an enlarged scale.
According to this invention we fix to the front heald staves 1-1 a metal rod 2
(see Fig. 1) to which is cast or fixed an inclined guide 3 for effecting the requisite
crossing of the warp threads 7, 8, and 14-15, and having in it two vertical
holes 4, 4, and through these holes 4, 4 are passed a pair of needles or eyed
wires 5-5 the lower ends of which are connected by elastics 6, 6 to the treadle or
lamb of the back heald staves.
In Fig. 2 instead of the rod 2 as shewn in Fig. 1 we employ two rods 2° 2° or
a sheet of metal stamped with a hole or slot 3* and the inclined guides 3, 3 form a
part of such sheet metal. The action of each apparatus is the same.
Two warp threads 7, 8 (see Fig. 3) which are to form the cross shed for one
side of the split up are carried from the warp beam directly under the back rest
and over the crank shaft. One of these threads 7 is then passed between the
healds 9. 9 and at one side of the back heald 10 and at the opposite side of the front
heald 1 so as to be slightly out of the straight line, and then to the shed near the
cloth or piece being woven, and this thread 7 always remains at the bottom of
the shed the other thread 8 is drawn through the eye 12 in one of the healds in
the back stave 10, thence to and through the loop or eye of the needle 5 in the
front stave 1. Each side of the split up is formed in the same manner, the adjacent
threads 14, 15 being threaded as above described.
The action is as follows: When the loom is in motion, and say the back heald
stave 10 rises, the back treadle also rises and this allows the needles 5, 5 to be
raised by the back healds pulling on the warp threads 8, 15 which pass through

page_text: the males and the eyes of the needles 5, 5 and at the same time the front stave 1
is lowered and the warp ends 8, 15 in the needles 5, 5 are carried up one side of the
standing warp ends 7, 14. When the back stave 10 is lowered and the front one 1
raised, the back treadle falls and takes with it the needles 5, 5 carrying with them
the warp ends 8, 15 so that the latter are moved to the opposite side of the station-
ary warp ends 7, 14 and a cross shed is formed when the operation is repeated.
The inclined portion of the guide 3 or 3º, 3º causes the warp threads to slip down
easily when required, and the tops of the needles 5, 5 are buried or sunk in the
vertical eyes (see Fig. 2) at this time, or are below the level of the guides (see
Fig. 1).
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) The improved apparatus for weaving split ups as herein described and sub-
stantially as illustrated by Figs. 1 and 2 of the annexed drawings.
(2) The method of and means employed for weaving split ups as herein described
and substantially as illustrated by the annexed drawings.
