PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Elastic Boot Webs.
We, JACKSON RÖHRS & CO. LIMITED of Parliament Street Mills, Derby, in
the County of Derby, Elastic Web Manufacturers and JOSIAH WOOD of
109 Whitecross Street, Derby, Weaver, do hereby declare the nature of this
invention to be as follows:-
The object of our invention is to produce an elastic boot web in which the face
of the web is covered with a minimum quantity of silk and to throw the whole of
the silk used in the manufacture thereof upon the face of the said web and further,.
to effect the proper balancing of the front and back of the web.
It is in connection with the motion of the binder threads that our invention more
particularly relates and we will now give a description of the said motion. At the
first shute of the shuttle or shuttles No. 1 binder stands at the top, No. 2 and No. 4
at the bottom and No. 3 in the centre. At the second shute No. 1 binder is at the
top, No. 2 at the bottom and No. 3 and No. 4 at the centre. At the third shute
No. 1 and No. 3 are at the bottom, No. 2 at the top and No. 4 in the centre. At
the fourth shute No. 1 is at the bottom, No. 2 at the top, No. 3 and No. 4 at the
centre.
The above operation is continually repeated by the binder threads producing the
web as already mentioned.
The 1st and 2nd binders may be operated with half tappets changing every other
shute and the 3rd and 4th binders with three-quarter tappets changing every fourth.
shute, standing for three in centre then dropping for one shute.
We may produce the motion by the use of nine shafts, and seven rocking poles.
or four rocking poles and barrel to control same, although the said motion may
possibly be produced by other means or arrangements.
The material produced will be considerably cheaper than that made by the
methods generally in use, only about one quarter of the silk being necessary to
produce an ordinary face, the quantity of silk will however depend upon the kind
of face required.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Elastic Boot Webs.
We,
JACKSON RÖHRS AND COMPANY LIMITED of Parliament Street Mills,
Derby in the County of Derby, Elastic Web Manufacturers, and JOSIAH WOOD
of 109 Whitecross Street, Derby aforesaid, Weaver, 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 :-
The object of our invention is to produce an elastic boot web in which the face
of the web is covered with a minimum quantity of silk or other facing yarn or
material, and to throw the whole of the said silk or facing material (carried by the
top shuttle) used in the manufacture thereof upon the face of the said web and
further, to effect the proper balancing of the front and back of the web.

page_text: It is in connection with the motion of the binder threads that our invention more
particularly relates and we will now describe the said motion, reference being had
to the accompanying drawing and to the letters of reference and numerals marked
thereon, the said drawing being an enlarged longitudinal section shewing the
construction of the web and upon which the back threads are omitted to avoid
confusion and as forming no part of our invention: the four binder threads are
lettered A, B, C, and D, the rubber is lettered E, "a," "a," is an imaginary centre
line and the different "picks" or "shutes" of the weft are shewn by the black dots
numbered 1, 2, 3, 4, 5, 6 &c.
As already mentioned it is in connection with the peculiar motion of the binder
threads A, B, C, D, that our invention more particularly relates and it may be
briefly described as follows. At the first shute of the weft No. 1 binder (A) stands
at the top, No. 2 (B) and No. 4 (D) at the bottom, and No. 3 (C) in the centre :
at the second shute of the weft, binder A. is at the top, B at the bottom, C and D
in the centre at the third shute of the weft, A and C are at the bottom, B at the
top, and D in the centre at the fourth shute, A is at the bottom, B at the top,
Cand D in the centre. This operation of the binder threads is continuously
repeated, which in conjunction with the motion of the rubber and back threads
forms the improved web having the whole of the silk or other facing material
thrown upon the face, the top side F being the face and bottom side G the back.
The rubber E as will be seen upon referring to the drawing rises and falls at every
shute of the weft.
It will be understood from the foregoing description that the 1st and 2nd
binders A and B stand at the top and bottom respectively and change to the bottom
and top respectively every other shute of the weft, and that the 3rd and 4th
binders C and D each stand in the centre for three shutes of the weft and drop to
the bottom for one shute, alternately.
The first and second binders may be operated with half tappets changing every
other shute and the third and fourth binders with three-quarter tappets changing
every fourth shute, standing for three in the centre and then dropping for one
shute. We may produce the motion by the use of nine shafts and seven rocking
poles or four rocking poles and barrel to control same, although the said motion
inay possibly be produced by other means or arrangements and we have in
consequence not illustrated any particular means of operating or producing the
motion of the various threads and rubber.
The material produced will be considerably cheaper than that made by the
methods generally in use only about one quarter of the silk or other facing
material being necessary to produce an ordinary face, the quantity of silk or other
facing material will however depend upon the kind of face required. The rubber
also is more protected and does not wear so quickly.
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
In the manufacture of an elastic boot web the action of the 1st and 2nd binders A
and B standing for two shutes of the weft at the top and bottom alternately and
the action of the 3rd and 4th binders standing for three shutes of the weft in the
centre and falling for one shute alternately substantially as and for the purposes
herein described and illustrated.
