improvements in the Construction of Vehicle Wheels.
I, EDMUND BROOK NUNN, of Royston, Hertfordshire, Gentleman, do hereby declare
the nature of this invention to be as follows:-
My invention relates to improvements in the construction of wheels for velocipedes
horseless carriages and other road vehicles.
In accordance with my invention I employ a steel or iron ring of suitable cross
section to serve as the rim or felloe of the wheel and I form the same with a transverse
hole at each point where it is desired to attach a spoke, the said hole being of
sufficient size to allow of the introduction as hereinafter described, of a screw-
threaded nipple of the kind ordinarily employed for attaching metal spokes to the rim
of a wheel.
I further provide a suitable radial hole passing from the transverse hole to the inner
periphery of the rim or felloe the said radial hole being of a size to receive the smaller
end of the screw-threaded nipple without giving passage to the enlarged end or butt
thereof.
I then introduce the screw-threaded nipple into the radial hole by passing it
through the transverse hole as above mentioned and proceed to attach the spoke to
the nipple in the usual way. The various spokes having been attached and their
tension regulated as desired I plug up the transverse holes in the rim or felloe with
tyre cement or other suitable material.
By the above means is provided a simple and effective method of constructing
wheels for velocipedes horseless carriages and other road vehicles.
1, EDWARD BROOK NUNN, of Royston, Hertfordshire, Gentleman, 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 :-
My invention relates to improvements in the construction of wheels for velocipedes,
horseless carriages and other road vehicles.
In accordance with my invention I employ a ring of appropriate material and
suitable cross section to serve as the rim or felloe of the wheel, and I form the same
with a transverse hole at each point where it is desired to attach a spoke, the said

which may be of the kind ordinarily employed for attaching metal spokes to the rim
of the wheel. I further provide a suitable radial hole passing from the aforesaid
transverse hole to the inner periphery of the rim or felloe, the said radial hole being
of a size to receive the smaller end of the screw-threaded nipple without giving
passage to the enlarged end or butt thereof.
The screw-threaded nipple is introduced into the radial hole by passing it through
the transverse hole above mentioned and the spoke is attached to the nipple in the
usual way.
In order that my invention may be clearly understood and readily carried into
effect I will proceed to describe the same more fully with reference to the
accompanying drawings in which :-
Figure 1 is a side elevation showing a portion of a wheel constructed according to
my invention, and
Figure 2 is a transverse section thereof taken on the line 1, 1.
A is the rim of the wheel, and a a are the transverse holes formed in said rim for
the passage of the screw-threaded nipples B, to which the spokes c are attached.
a', a' are the radial holes which are formed upon the inner periphery of the rim for
the reception of the smaller end b' of the said nipples.
The various nipples having been introduced into the radial holes a' and attached
to the spokes c, the tension of the spokes is properly regulated by revolving the said
nipples in the usual manner. I then plug the transverse holes a in the rim or felloe
with tyre cement or other suitable material in order to prevent the loosening of
the nipples and to impart a neat appearance to the wheel.
My improved wheel is simple in construction and can be readily repaired in the
event of a spoke becoming bent or broken, by removing the cement from the
transverse hole corresponding to the bent or broken spoke, and detaching the nipple.
The spoke requiring attention can then be repaired or replaced by a fresh one,
and after the replacement of the nipple the transverse hole is again plugged with
cement.
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:
1. A vehicle wheel having its rim formed with a series of transverse holes
communicating with radial holes for the reception of spoke nipples, substantially as
described.
2. A vehicle wheel constructed substantially as described with reference to the
accompanying drawings and for the purpose specified.
