Improvements in Fasteners for Application to Woven Driving Belts
I FRANK REDDAWAY of Cheltenham Street, Pendleton, in the County of Lancaster,
Manufacturer of Machine Belting, do hereby declare the nature of this invention to
be as follows:-
My said invention relates to fasteners adapted to secure together the ends of woven
driving belts or bands used for transmitting motion as is well understood. It will be
readily evident that woven belting has peculiarities which may render a fastener which
is effective upon leather belting or other belting of homogeneous material or compound
perfectly useless when applied to a woven belt. For example a fastener which lays
hold upon the weft without securing at the same time the warp is not likely to form a
secure joint. According to my invention I have devised a metallic fastener which is
light and inexpensive and at the same time perfectly secure. The improved fasteners
may be made in various ways and of different metals but I prefer to form them in cast
malleable iron. The fastener consists in its simplest form of a flat or slightly curved
plate of an oblong form and of a length about equal to the breadth of the belt and
furnished on the side next the belt with teeth or prongs made thin and flat so as to
present an oblong or oval in cross section. These teeth may be formed at or near each
side of the backing or plate and may be made in pairs curving away from each other
at the points. The greatest length of the oblong or oval section of the teeth stands
at right angles to the length of the plate so that when laid on or over the abutting
ends of the belt to be connected, and driven in, the teeth enter easily between the
warps and pierce the belt. A metal block or hard substance being provided beneath
the belt, the teeth as they emerge on the inner side of the belt are diverted respectively
in the direction of their curves and are turned over or clenched down on the inner
side of the belt and across the warps which are thus firmly held between the plate and
the clenched teeth or the protruding teeth may be clenched by a hammer or tool:
These portions of the weft which are within the range of the teeth are also laid hold
of and firmly held, the result being that an extremely secure and firm holdfast is
obtained and the joint is practically almost if not quite as strong as any other portion
of the belt. The improved woven belt fastener may be made with modifications in the
grouping number and position of the teeth and in the shape and proportions of the
plate so long as the principle is retained of teeth folding over and clenching down
upon and across the warp in the manner hereinbefore indicated. By a modification
of the invention I might cast, stamp or otherwise produce the plate separately and
punch or form slots in the plate corresponding to the position of the aforesaid fixed
teeth or prongs. I likewise produce separate staple formed or headed teeth or prongs
either curved at the points or straight and formed of the same metal as the plate or
from wrought iron, sott steel or other ductile metal and pass them through the slots or
perforations in the plate and through the belt and turn over or clench the said points
so as to secure the whole firmly together. By a further modification when the plate
is made of sufficiently ductile metal, I might press or stamp a sufficient number of
the said teeth or prongs from the thickness of the plate itself, the teeth being passed
through the belt and turned over or clenched as in the former instances.

Improvements in Fasteners for Application to Woven Driving Belts.
I FRANK REDDAWAY of Cheltenham Street Pendleton in the County of Lancaster
Manufacturer of Machine Belting 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 and accompanying drawings:-
My said invention relates to fasteners adapted to secure together the ends of woven
driving belts or bands used for transmitting motion as is well understood. It will be
readily evident that woven belting has peculiarities which may render a fastener which
is effective upon leather belting or other belting of homogeneous material or compound
perfectly useless when applied to a woven belt. For example a fastener which lays
hold upon the weft without securing at the same time the warp is not likely to form a
secure joint. According to my invention I have devised a metallic fastener which is
light and inexpensive and at the same time perfectly secure.
To render my invention perfectly clear I will now proceed to describe the same with
reference to the accompanying sheet of illustrative drawings.
Fig. 1 is a side view of my improved fastener before being applied to the woven
belt.
Fig. 2 is an end view.
Fig. 3 is a view similar to Fig. 1 showing the fastener applied to the woven belt.
Fig. 4 is an end view.
Figs. 5, 6, 7, 8 and 9 illustrate modifications of the fastener.
The improved fasteners may be made in various ways and of different metals but
under the simplest form they are made of cast malleable iron.
The fastener consists in its simplest form of a flat or as shown in Figs. 1 to 4 a
slightly curved plate a of an oblong form and of a length about equal to the breadth
of the woven helt and furnished on the side next the belt with teeth or prongs c
made thin and flat so as to present an oblong or oval in cross section. These teeth c
may be formed at or near each side of the backing or plate a and may be made in
pairs curving away from each other at the points as shown. The greatest length of
the oblong or oval section of the teeth stands at right angles to the length of the
plate so that when laid on or over the abutting ends bb of the belt to be connected, and
driven in, the teeth c enter easily between the warps and pierce the belt a. A metal
block or hard substance being provided beneath the belt, the teeth c as they emerge
on the inner side of the belt are diverted respectively in the direction of their curves
and are turned over or clenched down on the inner side of the belt as clearly shown
in Fig. 3 and across the warps which are thus firmly held between the plate a and the
clenched teeth c or the protruding teeth may be clenched by a hammer or tool. These
portions of the weft of the helt b which are within the range of the teeth are also
laid hold of and firmly held the result being that an extremely secure and firm holdfast
is obtained and the joint is practically almost if not quite as strong as any other
portion of the belt. The improved woven belt fastener may be made with modifications
in the grouping, number and position of the teeth and in the shape and proportions of
the plate so long as the principle is retained of teeth folding over and clenching down
upon and across the warp of woven driving belts in the manner hereinbefore indicated.
By a modification of the invention which is illustrated in Figs. 5, 6, 7 and 8, I cast
stamp or otherwise produce the plate a separately and punch or form slots a¹ in the
plate corresponding to the position of the aforesaid fixed teeth or prongs c. I likewise
produce separate staple formed or headed teeth or prongs c¹ shown separately at Fig. 8
either curved at the points or straight and formed of the same metal as the plate or
from wrought iron, soft steel or other ductile metal and pass the said staple teeth
through the slots or perforations a' in the plate a and through the belt b and turn over
or clench the said points of the teeth c' so as to secure the whole firmly together. By
a further modification which is illustrated by Fig. 9 when the plate a is made of
sufficiently ductile metal, I might press or stamp a sufficient number of the said

page_text: teeth or prongs c from the thickness of the plate itself the teeth being passed through
the belt and turned over or clenched as in the former instances.
Having now particularly described and ascertained my said invention and in what
manner the same is to be performed I declare that what I claim is :-
1. The improved fasteners for application to woven driving belts consisting of a
plate or backing in combination with teeth either part of the plate or separately formed
therefrom the breadth of the said teeth being at right angles to the length of the plate
and sufficiently thin to enter easily between the warps and to clench down upon and
hold the same and also a portion of the weft substantially as hereinbefore described and
as illustrated.
2. The improved fastener for application to woven driving belts substantially as
described and as illustrated in Figs. 1 to 4.
3. The improved woven driving belt fastener having the teeth formed separately
from the plate substantially as described and as illustrated in Figs. 5 to 8.
4. The improved woven driving belt fastener having teeth pressed from the plate
substantially as described and as illustrated in Fig. 9 of the drawings.
