IMPROVEMENTS IN DRIVING BELT OR MACHINE STRAP FASTENERS AND IN THE TOOLS FOR APPLYING THE SAME
Year: 1882

page_text: LETTERS PATENT to William Henry Chase of 16 Little Trinity Lane in the
City of London for an Invention of " IMPROVEMENTS IN DRIVING BELT OR
MACHINE STRAP FASTENERS AND IN THE TOOLS FOR APPLYING THE SAME."
PROVISIONAL SPECIFICATION left by the said William Henry Chase at
the Office of the Commissioners of Patents on the 1st August 1882.
WILLIAM HENRY CHASE of 16 Little Trinity Lane in the City of London
"IMPROVEMENTS IN DRIVING BELT OR MACHINE STRAP FASTENERS AND IN THE
TOOLS FOR APPLYING THE SAME
"
This invention relates to belt fasteners made for connecting the two ends of
machine bands together.
Many devices for this purpose have been employed and patented some in the
form of anchor pallets some in the form of loops or, flattened rings leaving eyes at
each end which passed through the leather and were held by cross pins.-these
were punched out of metal but the expense of making them and the cost of the
material hard brass prevented any great adoption of them, where formed out of
brass wire the ends being turned over the material was not strong enough to resist
the pull on the belt and they consequently gave way.
"
In this my invention I use steel only in the form of slightly flattened round wire
a round wire unflattened or square steel wire
This being cut into convenient lengths is bent into an oblong ring each
extremeity of the oblong ring being formed into an eye the ends of the wire
bend down on to and in close contact with the centre the but ends of the wire
nearly touching. The length of the now complete fastener is so calculated that the
turned down ends of the wire are held down by the leather that is the belt being
slotted the eyes project through the leather and a cross pin passes through them
but the ends of the wire in contact with the middle or centre of the wire are
embedded in the leather and thus prevented from rising, the eye of the loop can not
open.

page_text: The further improvement in the tools for slotting the leather consists in
providing a cheaper and equally convenient tool for slotting the leather in place of
the expensive apparatus now used called cutting pliers. In this invention I use a
chisel of the proper width having its edge sharpened like the edge of a turners
chisel the stem of the chisel is surrounded by a perforated collar and from the
collar projects a stem or guide one or two inches and at the distance from the edge
of the leather it is required to cut the slot by means of the chisel the collar and the
guide therefore slide up and down the stem of the chisel and when the guide is
applied to the edge of the leather and the chisel thrust down into the leather the
slot is made at. the proper distance from the edge and every successive slot made
will be equidistant from the edge of the leather

IMPROVEMENTS IN DRIVING BELT OR MACHINE STRAP FASTENERS AND IN THE

"
This invention relates to belt fasteners made for connecting the two ends of
machine bands together.
Many devices for this purpose have been employed and patented some in the
form of anchor pallets, some in the form of loops or flattened rings leaving eyes at
each end which passed through the leather and were held by cross pins. These
were punched out of metal but the expense of making them and the cost of the
material, hard brass, prevented any great adoption of them; where formed out of
brass wire the ends being turned over the material was not strong enough to resist
the pull on the belt and they consequently gave way.
In this my invention I use steel only in the form of slightly flattened round
wire, or round wire unflattened or square steel wire.
This being cut into convenient lengths is bent into an oblong ring each extremity
of the oblong ring being formed into an eye the ends of the wire bend down onto
and in close contact with the centre the butt ends of the wire nearly touching.
The length of the now completed fastener is so calculated that the turned down ends
of the wire are held down by the leather, that is the belt being slotted the eyes
project through the leather and a cross pin passes through them, but the ends of the
wire in contact with the middle or centre of the wire are embedded in or held down
by the leather and thus prevented from rising, the eye of the loop cannot open.
The further improvement in the tools for slotting the leather consists in
providing a cheaper and equally convenient tool for slotting the leather in place of
the expensive apparatus now used called cutting pliers. In this invention I use a
chisel of the proper width having its edge sharpened like the end of a turners chisel
the stem of the chisel is surrounded by a perforated collar and from the collar
projects a stem or guide one or two inches and at the distance from the edge of the
leather it is required to cut the slot, by means of the chisel, the collar and the
guide therefore slide up and down the stem of the chisel and when the guide is
applied to the edge of the leather and the chisel thrust down into the leather, the
slot is made at the proper distance from the edge and every successive slot made
will be equi distant from the edge of the leather.
In the Drawings forming part of this Specification.
Figures 1 and 2 are views of two sizes of the fastener shewing the ends turned
down and butted with the loops for the cross wire.
Figure 3 the pin or wire passing through the eyes.
Figure 4 the belt put together the ends of the eyes being held down by the ends
of the belt and the cross wire passing through
Figure 5. section through the belt, the eye in place, the pin in section
Figure 6 slotting chisel and gauge the chisel stem a. sliding through the socket b
the blade set at / inch space from the guide c. which is held against the end of
the leather belt when the slit is to to be cut by a blow of a mallett on the chisel.
Having now described and particularly set forth the nature of the said invention.
and the manner of carrying the same into effect I would have it understood that
what I claim is :-
1st. The eyes for fastening the ends of leather belts made of steel of either round

page_text: square or oblong section in the shape and form and for the purpose substantially
as described.
2nd I claim the slotting chisel as described for the purpose substantially as
described.
In witness whereof I the said William Henry Chase have hereunto set my
hand and seal this Thirtieth day, of January in the year of our Lord One
thousand eight hundred and eighty three.
