Improvements in Fastenings for Metal Tyres or Rims for Velocipedes,
and for like purposes.
I, GEORGE DENIS ROLAND BUNTING, a Member of the Firm of Robert
Bunting and Sons, of The County Steel Works, Arundel Lane, Sheffield, in the
County of York, Manufacturer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to the manner in which I construct and arrange fastenings
for use upon steel or metal tyres or rims, whereby I am enabled to employ strip or
strips of metal or sheet metal of even thickness, or uneven thickness with a bead or
beads running the length of the strips, instead of tubes in the construction of the
wheel rims, and to produce a strong and secure joint of such rims.
In carrying my invention into effect I employ a steel or other metal wire or strip
which I arrange within the rim of the wheel and I bring the ends of this wire
together to form a ring hoop or band for fastening and holding together the rim
itself. This tightening ring I prefer to arrange one on each side of the central
portion of the rim within a specially formed groove or channel formed within the
rim for the purpose. The ends of the loops or bands I bring together by means of
a socket or nut working upon a thread or threads arranged preferably as right and
left hand so that both ends may be drawn together at once. Instead of employing
a nut and socket I sometimes make each end to engage with the other by means of
claws or shoulders formed thereon, or 1 place a collar or sleeve over the end of the
wire or band and braze or solder the joint to form one piece or hoop when brought
together in position to secure the rim from opening.
I am enabled by this system of holding the rim together to employ strip metal
instead of tubular for the construction of the wheel rims, and I arrange my loops
or bands within the rims so as to be capable of working with any desired form of
tyre or section of rim which it may be desired to employ.
Instead of using round wire I sometimes make my loops or bands of flat steel or
other section and I secure the ends together by means of rivets or other like
attachments.
I prefer to apply my securing rings of wire to wheels in which the section of the
rim is such that two ribs or channels are formed for the rings to lie in, one on each side
of the centre of the rim, but I do not limit the application of my tightening rings
or securing loops to any particular shape of tyre or rim; and I sometimes dovetail
or solder the meeting surfaces of the rim together in addition to employing the
tightening or securing bands. The dovetailing or soldering being necessary to
enable me to keep the rim temporarily in position and also for the purpose of
forming an even surface to the metal.

Improvements in Fastenings for Metal Tyres or Rims for Velocipedes,
and for like purposes.
I, GEORGE DENIS ROLAND BUNTING, a Member of the Firm of Robert
Bunting and Sons, of The County Steel Works, Arundel Lane, Sheffield, in the
County of York, 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 :-
This invention relates to the manner in which I construct and arrange fastenings
for use upon steel or metal tyres or rims, whereby I am enabled to employ a strip
or strips of metal, or sheet metal of even thickness, or uneven thickness with a bead
or beads running the length of the strips, instead of tubes in the construction of
the wheel rims, and to produce a strong and secure joint of such rims.
In the accompanying sheet of explanatory drawings,
Figure 1 is a sectional elevation of my improved rim, and Figure 2 is a sectional
view of the rim with its attachments shown in perspective.
Figures 3, 4, 5, 6 and show the methods of connecting the ends of the fastening
or binding wires together.
Figure 8 is a side elevation of a portion of my rim showing the joint.
Figure 9 is a general front elevation of the wheel with a tyre attached.
In carrying my invention into effect I employ a steel or other metal wire or
strip A, which I arrange within the rim B of the wheel, and I bring the ends of
this wire together to form a ring hoop or band for fastening and holding together
the rim itself. These tightening rings A A' I prefer to arrange one on each side
of the central portion of the rim B within a specially formed groove or channel B¹ B'
formed within the rim for the purpose. The ends of the loops or bands I bring
together by means of a socket or nut (, working upon a thread or threads arranged
preferably as right and left hand, so that both ends A may be drawn together at
once. Instead of employing a nut and socket I sometimes make each end to engage
with the other by means of claws a a¹ or shoulders formed thereon, or I place a
collar and nut F or a jointing sleeve E over the end of the wire or band, and I then
braze or solder the joint or sleeve to form one piece or hoop when the ends are
brought together in position to secure the rim A from opening.
Within the central portion of the rim I place a bed strip or plate K which I
carry round the entire circumference of the rim sometimes uniting the ends by
riveting brazing or soldering. I prefer to form this band or bed strip with
channels or ear grooves k, k, for the binding wires or loops to fit or rest in as
shown in Figure 2. When dispensing with end connections for this inner band or
bed strip K, I cause the binding wires or loops A A' to keep the band in position
upon the rim.
I am enabled by this system of holding the rim together to employ strip metal
instead of tubular, for the construction of the wheel rims, and I arrange my
loops A A' and band K within the rim, so as to be capable of working with any
desired form of tyre H, or section of rim which it may be desired to employ.
Instead of using round wire I sometimes make my loops or binding bands of flat
or other section and of steel or other suitable metal, and I secure the ends together
by means of rivets or other like attachments.
The three thicknesses of metal at the central lower portion of the rim, enables
me to make a substantial attachment thereto by the spokes, which I secure in any
ordinary manner.
I prefer to apply my securing bands or my rings of wire to wheels in which the
section of the ring is such, that two ribs or channels are formed for the bands or
rings to lie in, one on each side of the centre of the rim; but I do not limit the
!

page_text: application of my tightening rings or securing loops to any particular shape of tyre
or rim, and I sometimes dovetail or solder the meeting surfaces of the rim together
as shown at b Figure 8 in addition to employing the tightening or securing bands.
The dovetailing or soldering being desirable to enable me to keep the rim
temporarily in position and also for the purpose of forming an even surface to the
metal.
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 construction of metal wheel rims for use upon cycles and for like purposes
in which strip, or sheet metal is employed, the ends of the strip or sheet being
joined together and kept in position by means of binding wires, loops or bands of
metal, substantially as, and for the purposes herein before described and as
illustrated in the accompanying drawings.
2. In a cycle or like wheel, the combination of metal binding loops or bands
with a central bed strip or inner band carried within a metal rim which is formed
out of sheet or strip metal, substantially as hereinbefore described and as illustrated
in the accompanying drawings.
Dated this 28th day of February 1894.
