Improvements in Apparatus Employed in the Weaving or Manu-
facture of "Slit-ups."
I; JOHN FAIRBURN the Younger of 88 Every Street Burnley in the County of
Lancaster, Temple Maker,. do hereby declare the nature of this invention to be as
follows:-
This invention relates to the manufacture of what are known as slit ups and
consists of an improved construction, arrangement and combination of parts employed
for operating the selvage needles whereby many of the contrivances and parts
heretofore employed are dispensed with and a greatly simplified and less complicated
apparatus is substituted.
I mount on the loom top a bracket or vertical arm, the upper end of which carries
a pair of pulleys, by elastic string or spiral springs connected with a. guide piece
for the upper pair of needles, the lower part of the bracket carries similar pulleys
which by means of straps, cords or chains are connected to the guide piece of the
lower pair of needles, the cords, straps, or chains pass between the lower. guide
pulleys and to studs in a crank arm, disc, or eccentric by the movement of which
the cords or chains is acted upon drawing down one set of needles and also trans-
ferring or crossing the straps or chains to the opposite guide pulleys whereby the
necessary crossing motion of the needles is effected, the other pair of needles being
connected by strap or .chain over the pulleys to the opposite side of the disc crank,
or eccentric, which will be drawn upwards so securing the requisite motion in both
directions. Or but one pair of needles may be operated vertically, but both are
crossed through the action of the crank eccentrics or spur wheel as described above.
The disc, crank, eccentric, or eccentrics receive their motion from cords connected
with. treadles from the under side of the loom driven from the tappet shaft or other
convenient going-part.

Improvements in Apparatus Employed in the Weaving, or Manu-
facture of i: Šlit-ups."
1, JOHN FAIRBURN," the younger of 88 Every Street, Burnley in the County: of
Lancaster Temple Maker, 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 the manufacture of what are known as "slit-ups" and
lenas," and consists of an improved construction, arrangement and combination of
parts employed-for, operating the selvage needles, whereby many of the contrivances
and parts heretofore employed are dispensed with and a. greatly simplified and less
complicated apparatus is substituted.
I.mount on the loom top a bracket or vertical arm, the upper end of which carries
pair of pulleys, by elastic string or spiral springs connected with a guide piece for
the upper pair of needles the lower part of the bracket carries similar pulleys and by
means.of straps cords or chains connects the guide piece of the lower pair of needles,
the cord, strap, or chain passes between the lower guide pulleys and to a stud in a
crank arm, disc, or eccentric by the movement of which the cord or chain is acted
D

page_text: upon drawing down one set of needles and also transferring the strap or chain to the
opposite guide pulley whereby the necessary crossing motion of the needles is effected
the other pair of needles being connected by strap or chain over the pulleys to the opposite
side of the disc or opposite crank, or eccentric, will be drawn upwards so securing
the requisite motion in both directions.
One pair of needles being operated vertically but both are crossed through the
action of the crank, eccentric, or can as described above. The disc, crank and
eccentric receive their motion from cords connected with treadles from the
under side of the loom driven from the tappet shaft or other convenient going
part.
Such being the nature and object of this invention, the following is a complete
description of same, reference being lad to the accompanying drawings in which
Fig. 1 is a front elevation of my improved "slilt up " motion.
Fig. 2 is a side elevation of same.
Figs. 3 and 4 are details or parts detached.
Fig. 14 is a front elevation of a modification of my improved slit up motion.
Fig. 2 is a side elevation of same.
Fig. 3 is a front elevation of the lower portion of the motion showing the crank
arm, eccentric, disc, and fork clearly.
Fig. 4 is a back view of Fig. 3.
Fig. 5 is a side elevation of same.
Fig. 6 is a detail.
According to this my said invention in Figs. 1 and 2 I amount on the loom top
rail, a bracket 1 carrying a vertical arm 2 which latter carries a pair of pullies 3" 4*
over which are passed elastic strings, or spiral springs 5" connected with a guide
piece 3 for the upper pair of needles 5:
The lower pair of needles 10 are also connected by elastic string or spiral spring-5*
with one of the pullies 3 or 4ª, and the lower part of the vertical armi 2 carries two
guide pullies 9 and the upper and lower sets of needles 5 and 10 are by straps,
cords or chains 6 6× connected with crank arms 7 one on each side of the disc or
eccentric 8. The disc or eccentric-8-has cast at the back of it a wheel or pulley 15
which by strap, chain or cord 16 fixed thereto is attached to the treadies on the
underside of the loom, driven from the tappet shaft, or other convenient going part
as usual.
The action is as follows:-
When the crank arm 7 and disc are moved from position a to position & the first
half of such motion draws down the needles 10 meanwhile the opposite strap 6* will
be slacked and the clastic 5 will have drawn up the needles 5 the remaining half of
the motion to point d will cross the straps 6* and 6 to the opposite pulleys 9* at the
same time crossing the needles the straps 6× becomes the pulling strap drawing down
the needles 5 whilst the strap 6 is slacked and its elastic 5 draw up the needles 10.
and such drawing down crossing and running of the needles 5 and 10 is alternately per-
formed at every partial rotation or oscillatory motion of the part 7 in an arc from
say about 4 to 8 o'clock, see enlarged view thus crossing the ends as desired.
A similar construction slightly modified is shown by Figs. 1 and 2ª wherein I
mount on the loom top rail a bracket 1 carrying a vertical arm 2 at the upper, and
lower end of which, are guide pieces 3. 3. these guide pieces 3. 3 carry a light
vertical frame 4 in which frame 4 are mounted the upper needles 5. 5 the vertical
frame 4 is connected by the rod, or bar 6 to the end of the crank 7 on the disc, or
wheel 8 which is mounted, and free to turn on the stud 9, in the lower part of the
vertical arm 2.
The lower pair of needles 10. 10 are carried by the upper end of a flat bar 11
mounted, and free to turn on the stud 12, the lower part of the flat bar 11 terminates in
a fork, or clip 13 which fork or clip 13 partly encloses, or encircles the eccentric,
or cam 14 cast on the back of the disc or wheel 8. The lisc or wheel 8, between the
crank 7 and eccentric, or cam 14 forms a pulley 15 to which is attached the straps,
chains, or cords 16. 16 the other ends of which are connected with the treadles on the

page_text: underside of the loom driven from the tappet shaft or other convenient going part as
ordinary.
The action is as follows.
A part revolution is given to the pulley 15 first in one direction, then in the
opposite one, by the two, straps, cords or chains, 16. 16 and the freadles, as described;
this motion of the pulley 15 imparts a like motion to the crank 7 and eccentric, or
cam 14, the crank by the connecting rod or bar 6 imparts an up and down motion
to the frame carrying the upper needles 5. 5 the vertical frame 4 working in the
guide piece 3. 3.
The eccentric, or cam 14 at the same time imparts a rocking, or oscillating motion
to the forked bar 11 which rocks on the stud 12 so that one set of needles 5. 5 have
an up, and down motion whilst the other set of needles 10. 10 have a to and fro
motion, and consequently the warp threads for forming the slit up which pass through
the eyes in the needles are crossed at every pick of the loom.
"
"
The top set of needles 5.5 carry the warp threads which from the bottom shed,
and the lower needles 10. 10 carry the warp threads for forming the top shed.
By using a combination of several sets of needles mounted in a suitable carrying
frame, or frames this invention can be employed in the weaving of that class of
goods known as "lenas "
the carrying frame being operated in a manner similar to
the single frame 4.
It will of course be obvious that the pulley 15 can be operated in other ways
than that above described as for instance by a toothed rack, the pulley 15 having
teeth on its circumference to engage with the said rack.
Having now particularly described and ascertained the nature and object of my
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The pulley or wheel 15 crank 7 straps 6× 6 for operating the needles 5. 10 as
herein fulley described and illustrated by annexed drawings.
2. The pulley or wheel 15 and crank 7 forked or clipping bar 11 and cam or
eccentric 14 all in combination for operating the needles 5. 5 and 10. 10 as herein
described and illustrated by Figs. 1^ and 24 of accompanying drawings.
