PROVISIONAL SPECIFICATION.
Improvements in Split or Selvage Motions of Looms for Weaving.
We JOHN HUNT of 39 Pitt Street, Accrington in the County of Lancaster,
Overlooker, and HEBER HEAP of 4 Robert Nutall Street Accrington, aforesaid,
Overlooker do hereby declare the nature of this invention to be as follows:--
<
"
This invention relates to improved appliances for weaving the "split" or
selvage" edges where two or more "pieces" are being woven in one loom, and the
object is to so weave and secure the edges or selvages that when cut or split" they
will not fray and this invention consists of improved appliances for crossing and
recrossing the warp threads nearest to the edge to be cut or split over and under the
weft so that the saine is held by and holds the warp and consequently when cut there
is no fraying.
According to this our said invention we fix on the crank shaft of the loom an
eccentric to a vertical arın of which is attached a cranked lover free to turn on a stud
fixed to the top rail of the loom. On the opposite ond of the lever to that attached to
the eccentric is another vertical lever to the lower end of which is fixed a slide piece
which works through the agency of the eccentric with an up and down motion in
bearings fixed by bracket to the top rail of the loom and fixed to the bottom of this
slide piece is a two pronged fork and at the end of each prong of the fork is an
eye "There is also a second two pronged fork having eyes similar to the above this
second fork is fixed to a short arm the fulcrum stud of which is on a bracket fixed
to the bearing through which the slide piece above mentioned works or to the top rail
of the loom To one end of this short arm is fixed a cranked finger on the end of
which is a lump operated upon by a worm on the heald rod,. which first turning one
way and then the other imparts by the worm and cranked finger and arm a to and fro
motion to the second fork.
C
In the two forks there are thus four eyes and through these eyes are passed the
four outside warp threads the top threads in the ordinary shed pass through the bottom
pair of eyes and vice versa so that when the loom is in motion two of the warp threads
receive an up and down motion and two of them a to and fro motion and thus to every
pick of the loom each pair of outside warp threads cross and the weft being picked
between the two is securely held by and holds the warp so that when the piece is 'cut
or "split" there is no fraying of the edges and a strong selvage is formed.

Improvements in Split or Selvage Motions of Looms for Weaving.
We JOHN HUNT of 39 Pitt Street, Accrington in the County of Lancaster,
Overlooker, and HEBER HEAP of 4 Robert Nutall Street, Accrington aforesaid,
Overlooker, 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 for weaving the "split" or "selvage"
edges where two or more "pieces are being woven in one loou, and the object is to
so weave and secure the edges or selvages that when cut or "split" they will not fray
and this invention consists of improved appliances for crossing and recrossing the

page_text: warp threads nearest to the edge to be cut or split, over and under the weft so that
the same is held by and holds the warp and consequently when cut there is no
fraying.
According to this our said invention we fix on the crank shaft of the loom an
eccentric to a vertical arm of which is attached a cranked lever free to turn on
a stud fixed to the top rail of the loom.
On the opposite end of the lever to that attached to the eccentric is another vertical
lever to the lower end of which is fixed a slide piece which works through the
agency of the eccentric with an up and down motion in bearings fixed by bracket to
the top rail of the loom and fixed to the bottom of this slide piece is a two pronged fork
and at the end of each prong of the fork is an
" eye."
There is also a second two pronged fork having eyes similar to the above this
second fork is fixed to a short arm the fulcrum stud of which is on a bracket fixed
to the bearing through which the slide piece above mentioned works or to the top
rail of the loom. To one end of this short arm is fixed a cranked finger on the
end of which is a lump operated upon by a scroll or worm on the heald rod, which
first turning one way and then the other imparts by the scroll or worm and cranked
finger and arm a to and fro motion to the second fork.
In the two forks there are thus four eyes and through these eyes aro passed the
four outside, warp threads the top threads in the ordinary shed pass through the
bottom pair of eyes and vice versa so that when the loom is in motion two of the warp
threads receive an up and down motion and two of them a to and fro motion and
thus to every pick of the loom each pair of outside warp threads cross and the weft
being picked between the two is securely held by and holds the warp so that when
the piece is cut or "split" there is no fraying of the edges and a strong selvage is
formed.
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 forming a part
of this specification in which :-
Fig. I is a front elevation of our improved "split" or selvage motion.
Fig. 2 is a side elevation of Fig. 1.
According to this our said invention we fix on the crank shaft 1. of the loom, a strap
eccentric 2 to a vertical rod or arm 3 attached to the eccentric 2 is connected the
cranked lever or arm 4, free to turn on a stud 5 fixed to the top rail 6 of the loom.
The opposite end of the lever 4 to that attached to the eccentric 2 is connected by
strap or link 7 with a vertical lever or slide 8. The eccentric and connections
imparting to the latter slide piece 8 an up and down motion in its bearing or slide
rest 9 formed in the bracket 10 which is bolted to the top rail 6.
To the lower end of the vertical slide piece 8 is bolted a two pronged fork 11
and in the end of each prong is formed an eye 12. 13.
A second two pronged fork 14 having the eyes 15. 16 is fixed to the arm 17
free to turn on its fulcrum stud 18 in the bracket 10, to the top of this arm 17
is bolted a bent finger 19 at the end of which is a "lump" or segment 21. which
is received in the scroll 22 on the heald rod 23.
When the loom is in motion an up and down motion is given to the first men-
tioned fork 11, by the eccentric 2, as described, whilst a to and fro motion is imparted
to the second fork 14 by the scroll 22.
It will thus be seen that in the two forks 11, 14 are four eyes 12. 13 and 15. 16.
and through these eyes are passed the four outside warp threads which with the
weft form the selvage. The two top threads in the ordinary shed pass through the
bottom pair of oyes 15. 16 which receive the to and fro motion, and the two bottom
threads in the ordinary shed are passed through the eyes 12. 13 or those which
receive the up and down motion. It will thus be seen that at every pick of the
loom each pair of outside warp threads cross and the weft being "picked" between
the two threads are interwoven in such a way that when the piece is cut in the
usual way there is no fraying of the edge but a perfect selvage is formed.

page_text: Having now particularly described and ascertained the nature and object of the
said invention and in what manner the same is to be performed we declare that
what we claim is :-

the purpose described, and substantially as illustrated by the annexed drawings.
