PROVISIONAL SPECIFICATION.
Improvements in Driving-belts.
1, JOHN TAYLOR of Whitewell Bottom Mill, Newchurch Lancashire, Manufacturer,
do hereby declare the nature of this invention to be as follows:-
The improvements relate to driving belts, and have for object the manufacture of
woven belts in such manner that they may have conveniently inserted in the edges
thereof, buffalo hide, leather, gutta-percha or other substance, which may form what
is known as a safe edge.
To accomplish this and to effect my improvements, I arrange the warp threads in
such manner that what will be understood as four fabric or four shed weaving will be
the result, and in which the top and bottom fabrics are arranged wider than the two
middle ones.
One shuttle is used as is the common method, and the order of
weaving is as follows:-The top shed is opened, at the first pick, the second shed, at
the second pick, the third shed at the third pick, and the fourth shed at the fourth
pick. Then the fourth shed is opened in reverse at the fifth pick, the third shed in
reverse at the sixth pick, the second shed in reverse at the seventh pick, and the first
shed in reverse at the eighth pick; when the whole operation is repeated. The
whole is bound together by means of binder warps as will be readily understood;
but at the edges, the top and bottom fabrics are not bound together, binding warps
only being employed in the central portion where the four fabrics are all super-
imposed.
By this means a woven belting is produced having indentations at each edge in
cross section, which may be of any depth desired.
Into these indentations I place the strips of buffalo hide, leather, gutta-percha, or
other substance and fasten therein by means of stitching or rivetting in the ordinary
manner.

COMPLETE SPECIFICATION.
Improvements in Driving-belts.
I, JOHN TAYLOR of Whitewell Bottom Mill, Newchurch Lancashire, Manufacturer,
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 improvements relate to driving belts, and have for object the manufacture of
woven belts in such manner that they may have conveniently inserted in the edges
thereof, buffalo hide, leather, gutta-percha, or other substance, which may form what
is known as a safe edge.
To accomplish this and to effect my improvements, I arrange the warp threads in
such manner that what will be understood as four fabric or four shed weaving will
be the result, and in which the top and bottom fabrics are arranged wider than the
two middle ones. One shuttle used as is the common method, and the order of
weaving is as follows:-
:-
The top shed is opened at the first pick, the second shed at the second pick, the
third shed at the third pick, and the fourth shed at the fourth pick. Then the fourth
shed is opened in reverse at the fifth pick, the third shed in reverse at the sixth pick,
the second shed in reverse at the seventh pick, and the first shed in reverse at the
eight pick; when the whole operation is repeated. The whole is bound together by

page_text: means of binder warps as will be readily understood; but at the edges, the top and
bottom fabrics are not bound together, binding warps only being employed in the
central portion where the four fabrics are all superimposed.
By this means a woven belting is produced having indentations at each edge in
cross section, which may be of any depth desired.
Into these indentations I place the strips of buffalo hide, leather, gutta-percha, or
other substance and fasten therein by means of stitching or rivetting in the ordinary
manner.
But that the improvements may be better understood, I will by the aid of the
accompanying drawings, proceed more fully to describe means employed by me.
Fig. 1 is a diagram shewing the order of
eaving; and
Fig. 2 is a transverse section illustrating the form of my improved woven driving
belt, while
Fig. 3 is a transverse section shewing the insertion, in the edges thereof, of buffalo
hide, leather, gutta-percha, or other substance, for the forming of what is known as
a safe edge.
Figs. 4, & 5, are plan views, shewing two modes of securing such inserted edge.
In Fig. 1, the numerals to the left represent picks or motions of the loom, while
those along the top represent warp threads. The crosses shew when such warp
threads are lifted or operated by the healds. The numbers representing warp threads
bracketed together into four pairs shew the four sheds of warp threads in the reed.
The top shed is opened at the first pick by lifting number one shaft; the second shed
is opened at the second pick by lifting number three; the third shed is opened at the
third pick by lifting number five; and the fourth shed is opened at the fourth pick
by lifting number seven. Then the fourth shed is opened in reverse at the fifth pick
by lifting number eight; the third shed is opened in reverse at the sixth pick by
lifting number six; the second shed is opened in reverse at the seventh pick by
lifting number four; and the first shed is opened in reverse at the eighth pick
by lifting number two; when the whole operation is repeated.
Fourfold fabric thus produced, is bound together in the central portion, where the
four fabrics are all superimposed, by means of binding warps, as will be readily
understood, but which binding warps are not shewn in the diagram.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
―
1. The weaving of fourfold fabric for woven belting, wherein the top and bottom
fabrics are wider than the two centre ones, and wherein indentations at each edge in
'cross section are produced, for the purpose and in manner substantially as herein
shewn and described.
2. Woven belting having indentations at each edge in cross section, and having
inserted therein strips of buffalo hide, leather, gutta-percha, or other substance, for
the purpose and in 'uianner substantially as berein shewn and described.
