Improvements in Split Up Motions of Looms for Weaving.
We JOHN HARDMAN BLACKBURN Book-keeper, ROBERT BLACKBURN, Weaver,
THOMAS FARRER-BAYNES and PERCY FARRER-BAYNES Manufacturers all of
India Mill, Blackburn in the County of Lancaster, do hereby declare the nature
of this invention to be as follows:-
This invention relates to improved appliances to be employed in connection with
looms when weaving "split ups" i.e. two or more widths or pieces in one loom, the
object being to ensure the outer warp threads being crossed whilst at the centre of
the shed, and with an equal strain or tension on each of the four ends.
According to this our invention we employ a light bracket fixed to the top rail
of the loom, and in the top of this bracket is a stud carrying a pulley which is
partly rotated in one direction by means of a strap connected in the heald_shafts
or the dobby, and in the reverse direction by means of a spiral spring. On the
stud is a disc to each opposite side of which is attached a rod and the lower ends
of these two rods work through a guide piece carried on the bracket. The lower
end of each rod carries a pair of needles one pair pointing upwards and the other
pair downwards and through the eyes of these needles, four adjoining warp threads
are passed two on each side of the split.
.
The action is as follows: When the loom is in motion the disc is partly rotated
first in one, then in the other direction, and the disc carries the upper ends of the
rods first to one side then to the other, and the needles at the lower ends also rise
and fall and cross from one side to the other and always at about the centre of
the shed. By this means the warp threads are crossed and interlaced with the
weft threads in the manner well known when weaving "split ups."
A guard is fixed to the bracket to prevent the warp threads being entangled.

Improvements in Split Up Motions of Looms for Weaving.
We JOHN HARDMAN BLACKBURN Book-keeper, ROBERT BLACKBURN, Weaver,
and THOMAS FARRER-BAYNES, and PERCY FARRER-BAYNES, Manufacturers,
all of India Mill, Blackburn, in the County of Lancaster, 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 improved appliances to be employed in connection with
looms when weaving "split ups," i.e. two or more widths or pieces in one loom,
the object being to ensure the outer warp threads being crossed whilst at the
centre of the shed, and with an equal strain or tension ou each of the four ends,
by the use and employment of apparatus hereinafter described, which is both
simple in its construction and efficient in its action.

page_text: Such, being the nature and object of our said invention, the following is a
complete description of same, reference being had to the accompanying drawings,
in which
Fig. 1 is a side elevation of the improved apparatus for purpose herein set
forth.
Fig. 2 is a front elevation of Fig. 1.
According to this our said invention, we employ a light bracket 1 fixed by
arm 2 and bolts to the top rail of the loom. In the top of the bracket 1 is a
stud 3 carrying a pulley 4, which is partly rotated in one direction by means of a
strap 5, connected to one of the heald shafts or to the dobby, and in the reverse
direction by means of the strap 6 and spring 7. On the stud 3 is also a disc 8, to
each opposite side of which is attached a rod 9. 10, and the lower ends of these
two rods 9. 10 work through a guide piece 11 carried on the bracket 1. The lower
end of each rod 9. 10 carries a pair of needles 12. 13, one pair 12 fixed to the rod 9
pointing upwards, and the other pair 13 fixed to the rod 10 pointing downwards;
and through the eyes of these needles 12. 13, the four adjoining warp threads are
passed, two on each side of the split. A guard 14 is fixed to the bracket I to
prevent the warp threads being entangled.
The action is as follows:-When the loom is in motion, the disc 8 is partly
rotated, first in one, then in the other direction, and the disc 8 carries the upper
ends of the rods 9. 10, first to one side, then to the other. The rods 9. 10 and
needles 12-13 rock in the guide piece 11 which forms a fulcrum, and the
needles 12. 13 at the lower ends are caused to rise and fall, and cross from one
side to the other, and always at about the centre of the shed. By this means the
warp threads are crossed and interlaced with the weft threads in the manner well
known when weaving "split ups."
"
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 ie:-
(1.) The general construction, arrangement, and combination of parts constituting
the improved split up motion, as and for the purpose herein described, and substan-
tially as illustrated by the annexed drawings.
(2.) The frame 1 disc 8 rods 9. 10, carrying the needles 12. 13 and the guide
piece 11, all in combination as and for the purpose herein described and substantially
as illustrated by the annexed drawings.
Dated this 10th day of January 1895.
