Looms for Weaving.
We, JOHN WILLIAM SHORROCK of 7 Trinity Terrace, and THOMAS BAYNES
TAYLOR of 43 Sudell Road, both of Darwen in the County of Lancaster, do hereby
declare the nature of our Invention for "A NEW OR IMPROVED "SPLIT" OR
SELVAGE MOTION EMPLOYED IN LOOMS FOR WEAVING," to be as follows:-
This invention relates to the construction of improved apparatus for weaving
the inner selvages when two or more "pieces" or cloths are being woven in a loom
and consists in mounting on the top rail or beam carrying the heald shafts a
suitable metallic fixing provided on the bottom end with a tongue or fork. On
the heald shaft is mounted a quadrant to which is attached a leather band or its
equivalent from this band is suspended two "gut" leashes which pass downwards
and round bowls mounted on the ends of the prongs of the fork, from whence they
ascend and are coupled to suitable elastic materials, the latter being attached to a
hook or other equivalents supported from the said top rail or beam. The " "gut"
leashes are guided by a cumber board fixed in any convenient manner to the tongue
or fork fixing, and are provided with eyes through which the warp threads pass,
receiving a rising and falling motion from the combined action of the heald shaft
and the elastic materials.
Immediately above the bowls are disposed suitable eyes through which the warp
threads pass; the lateral or crossing motion requisite to knit the threads together
with the "weft" being effected by the reciprocating motion of the eyes in the
'gut" leashes round the bowls which places the warp threads on each side of the
prongs alternately, the same being kept free from the warp threads by a guide
suspended froni the said fixing.
The novelty of this invention is its simplicity by which an increased number of
'pieces" can be woyen in a loom at a time, enabling the loom to be worked either
way without breaking or interfering with the selvage yarn,

OR
We, JOHN WILLIAM SHORROCK of 7 Trinity Terrace and THOMAS BAYNES
TAYLOR of 43 Sudell Road, both of Darwen in the County of Lancaster, do hereby
declare the nature of our said Invention for "A NEW OR IMPROVED "SPLIT "
SELVAGE MOTION EMPLOYED IN LOOMS FOR WEAVING," 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 construction of improved apparatus for weaving
the inner selvages when two or more "pieces or cloths are being woven in a
loom, and consists in mounting on the top rail or beam, carrying the heald shafts,
a suitable metallic fixing provided on the bottom end with a tongue or fork. On
the heald shaft is mounted a quadrant to which is attached a leather band or its
equivalent: from this band is suspended two leashes which pass downwards and
round bowls mounted on the ends of the prongs of the fork, from whence they
ascend and are coupled to suitable elastic material, the latter being attached to a
hook or other equivalents supported from the said top rail or beam. The leashes
are guided by a comber board fixed in any convenient manner to the tongue or
fork fixing, and are provided with eyes through which the warp threads pass,
receiving a rising and falling motion from the combined action of the heald shaft
and the elastic material.
Immediately above the bowls are disposed suitable eyes through which the warp
tbreads pass the lateral or crossing motion requisite to knit the threads together
with the "weft" being effected by the reciprocating motion of the eyes in the
leashes round the bowls which places the warp threads on each side of the prongs
alternately, the same being kept free from the warp threads by a guide suspended
from the said fixing..
"
The novelty of this invention is its simplicity by which an increased number of
'pieces" can be woven in a loom at a time, at the same time allowing of the
loom being worked in either direction without breaking or interfering with the
selvage yarn.
"
Fig. 1 is a side elevation of our improved "split" or selvage motion for weaving
the inner selvages when two or more "pieces or cloths are being woven in a
loom Fig. 2 is a front view of same and Fig. 3 is a sectional plan through line A. B.
in Fig. 1.
To the top rail or beam C employed for carrying the heald shaft D is attached
the fixing E by the bolt F. The bottom end of the fixing E is provided with the
prongs G forming a fork or tongue. On the bottom end of the prongs G are
mounted the bowls H on the pins or centres I. Immediately above the pulleys H
are disposed the eyes or eyelets R through which the warp threads J pass from the
warp beam. On the heald shaft D is mounted the pulley K-which may be a
quadrant to which is attached the leather or other suitable flexible band Ŏ. To
the band O the leashes M are attached by the cords 2 or other equivalents. The
leashes M descend and pass round the bowls H and ascend on the opposite side

page_text: where they are secured to the elastic band 3, the latter being attached to the
hook N supported from the fixing E as shewn, or from any convenient position of
the top rail or beam C. The leashes M are guided by the comber board P fixed to
the fixing E by the bolt X. The leashes are provided with the eyes or eyelets S
through which the warp threads T pass. The warp threads J and T travel in the
direction indicated by the arrows in Fig. 1. The warp threads T pass through
the eyes 5 of the guide W attached to the fixing E for the purpose of preventing
entanglement. To prevent the warp threads T becoming entangled with the
remainder of the warp threads in close proximity to the apparatus they are
protected by the guard L attached to the fixing E.
This apparatus operates as follows:-The pulley K receives a reciprocating
motion from the heald shaft D by which the leashes M are raised and lowered and
the eyelet holes S place the warp threads T first on one side of the prongs G and
warp threads J and then on the other as shewn in dotted lines in Fig. 3. When
the pulley K is rising the ends of the leashes M attached to the band O the
opposite ends are etretching the elastic band 3, which when the pulley K commences
to make the return stroke the stretched or extended elastic band 3 reverses the
travel of the leashes M; the reciprocating motion of the eyelets S round the
pulleys H being effected by the combined action of the pulley K and the elastic
band 3.
"
Figs. 5 and 6 show an arrangement we adopt for working or operating our
improved "split" or selvage apparatus when applied to looms wherein heald shafts
are dispensed with, being substituted by the "dobby" or index machine. This we
accomplish by mounting the lever 6 on the stud or centre 7 on the side frame 8 of
the loom. The leashes M are attached to the lever 6 by the cord 2, the opposite
ends being attached to the elastic band 3; the latter passes upward from the leashes
and over the guide pulley 9 to the hook N. Owing to the close position of the
index machine or "dobby' to the rail C the rod N is considerably shortened in
height and bent to allow of the necessary length of elastic band 3. To facilitate
the movement of the elastic band 3 the guide pulley 9 is mounted on the rod N as
shewn, over which the band 3 passes from the leashes M to the hook N. The
lever 6 receives its motion from the lever Z attached to the "dobby
or index
machine V by means of the cord 10, or its equivalent. In this case the recipro-
cating motion of the leashes M is effected by the combined action of the lever 6
and the elastic band 3.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is:-
1. The method, substantially as herein described, of operating the leashes M
reciprocally round the bowls H so as to place the eyelets S with their respective
warp threads alternately on each side of the prongs G and warp threads J, by
connecting them to an elastic band and to a pulley, quadrant, or lever receiving a
reciprocating motion from the heald shaft or other equivalent part of the loom.
2. For carrying out the method herein before described, the construction and
arrangement of apparatus, applied and operating substantially as described and
illustrated by the accompanying drawings.
