PROVISIONAL SPECIFICATION.
Improvements in and relating to Laminated Leather Machinery
Driving Belts.
I, JAMES HENDRY, of 252, Main Street, Bridgeton, in the County of the City
of Glasgow, Manufacturer, do hereby declare the nature of my invention to be
as follows:-
This invention has reference to and comprises improvements in and relating
to laminated leather machinery driving belts of the character described in the
Specification of my and Alexander Hendry's prior Patent No. 504 January 9,
1892, and consists of improvements in the method of connecting two or more
breadths of laminated belting together to form belts of any width.
By one simple method the outside strips of the breadths to be joined together
are made deeper at the meeting sides, so as to project above the other strips
while level with them on the under surface, and these projecting parts are
stitched together in any suitable or ordinary manner. In this way any number
of breadths of limited width may be connected together to form a belt of any
desired width.
By another method one or it may be more loose strips are interposed between
the meeting edges of the breadths and these are then stitched together, the
threads passing through the loose strips and so binding all together. To enable
this to be done an angled groove is cut along the length of the breadths inside
of the outermost strips to allow the thread to be passed through the outer and
interposed strips. The interposed strip or strips would preferably be grooved
along their sides to accomodate the securing threads of each breadth and enable
all the strips to lie close.
By another method the outermost strips of the meeting edges of the breadths
are made of less depth than the others and the next inner strip is made deeper
and turned over to the outside where the meeting strips of the adjacent breadths
are stitched together. Instead of using two strips one broader strip may be
used each side of which is stitched with the breadth and forms the second layer
of same.
The various breadths may also be laced together preferably by leather strips,
though other materials may be used.
In this case the lacing strip is passed between the stitched and inside of each
other strip or strips, preferably two, of the meeting breadths, alternately from
side to side. The outer strips which are thus laced together are preferably
made of less depth than the others so as to keep the surfaces level when the
lacing is effected, any suitable instrument being used to open a space between
the strips to allow the lacing material to be passed through.

Driving Belts.
I, JAMES HENDRY, of 252, Main Street, Bridgeton, in the County of the City
of Glasgow, Manufacturer, do hereby declare the nature of my invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the foliowing statement in writing reference being made
to the accompanying drawings:
This invention has reference to and comprises improvements in and relating
to laminated leather machinery driving belts of the character described in the
Specification of my and Alexander Hendry's prior Patent No. 504 January 9
1892, and consists of improvements in the method of connecting two or more
breadths of laminated belting together to form belts of any width.
By one simple method, as illustrated by Figure 1, the outside strips a, b, of
the breadths A, B, to be joined together are made deeper at the meeting sides,
so as to project above the other strips, while level with them on the under or
working surface, and these projecting parts are stitched together at d in any
suitable or ordinary manner. Figure 2 illustrates a similar method in which
the strips a, b, are made of the same depth as those in the body of the breadths A, B
the edges of the strips c being slightly bevelled as at e¹ to allow the stitching
at d to be effected. In this way any number of breadths of limited width may
be connected together to form a belt of any desired width. Figure 3 illustrates
a modification of the foregoing methods in which the breadths are secured by
stitching together, as at d, the two outer strips a, a, b, b1, of each breadth, the
two next strips e being made of less depth to allow the stitching to be more
easily effected, and the strips a, b, being made of sufficient depth as to fold
down on the top of the strips e, where they may be cemented down if desired.
By another method, illustrated by Figure 4, one or as shown two, or it may
be more, loose strips f are interposed between the meeting edge strips a, b, of
the breadths A, B, and these are then stitched together at d, the threads passing
through the loose strips and so binding all together. To enable this to be done,
an angled groove f is cut along the length of the breadths A, B, inside of the
outermost strips a, b, to allow the thread to be passed through the outer strips a, b,
and interposed strips f. The interposed strip or strips would preferably be
grooved along their sides to accomodate the securing threads of each breadth
and enable all the strips to lie close.
By another method, illustrated by Figure 5, the outermost strips a, b, of the
meeting edges of the breadths A, B, are made of less depth than the others and
the next inner strips a¹, b', are made deeper and turned over to the outside where
the meeting strips of the adjacent breadths are stitched together as at d.
Instead of using two strips a¹, 61, one broader strip a2 may be used each side
of which is stitched with and to one of the breadths and forms the second layer
or strip of each.
The various breadths may also be laced together, as illustrated by Figure 7,
preferably by leather strips, though other materials may be used. In this case
the lacing strip g is passed between the stitches and inside of each outer strip
or strips, preferably two a, a, b, 61, of the meeting breadths A, B, alternately
from side to side. The outer strips which are thus laced together are preferably
made of less depth than the others so as to keep the surfaces level when the
lacing is effected, any suitable instrument being used to open a space between
the strips to allow the lacing material to be passed through.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is-
First. The improvements in laminated leather machinery driving belts by
which belts of any desired width may be formed from a number of breadths
secured together substantially as herein described and illustrated by the accom-
panying drawings.
Second. The method of forming laminated leather machinery driving belts
of any desired width by securing together two or more breadths substantially
as herein described and illustrated by the accompanying drawings.
Third. The method of forming laminated leather machinery driving belts of
any desired width by stitching together the outer strips of two or more breadths
substantially as herein described and illustrated by Figures 1, 2, and 3 of the
accompanying drawings.

Fourth. The method of forming laminated leather machinery driving belts
of any desired width by stitching together the outer strips of two or
breadths with one or more loose strips interposed substantially as herein described
and illustrated by Figure 4 of the accompanying drawings.
Fifth. The method of forming laminated leather machinery driving belts of
any desired width by stitching together two or more breadths by means of
strips a, b, made broader for the purpose substantially as herein described and
illustrated by Figure 5 of the accompanying drawings.
Sixth. The method of forming laminated leather machinery driving belts of
any desired width by securing together two or more breadths by means of the
strip a stitched to and fórming part of each breadth substantially as herein
