Improvements in or connected with Rims or Felloes for Wheels.
I, WILLIAM BOWDEN of Barlow Range, Chorlton-cum-Hardy, in the Count v
of Lancaster Director do hereby declare the nature of this invention to be a >
follows:-
This invention relates more particularly to wheels to be fitted with pneumatic
and other flexible tyres and consists in improvements in the construction of rims
which thereby may be made readily applicable to wheels having wooden felloes,
the objects of this invention being chiefly to obviate the necessity of shrinking an
endless hoop or rim upon the felloe or of removing an existing hoop when it is
desired to fit a pueumatic or other flexible tyre or tread to such felloe or wheel
and to construct a special rim in such manner that it is secure as well as readily
removable.
In carrying out my invention, in some cases I form a light metal rim of H section
or approximately so and bend the rim round so that the channels lie one above the
other, the upper or outer one being for the purpose of containing the flexible tyre,
and the lower one being formed to sit upon the wooden felloe or upon the metal
rim or hoop secured thereto. I form the H section rim so that the ends may butt
together at the joint and I may secure this rim by screws or bolts at the joint or at
intervals round the rim to the wooden felloe or to the iron rim or hoop binding
the felloe together. Preferably however I form the centre web of the H section
felloc at one end to overlap that part of the other end, at the joint and secure
the two parts together by bolts or screws, or to the felloe or binding hoop in a
similar manner.
In some cases I form the H section rim-length or bar from a flat strip of metal
by turning or bending up the edges to first form deep sides then turning or bending
over outwardly the edges for a portion of their depth so that the sides project
below the bottom or web and form an inverted channel.
In other cases I may form the H section rim from two separate lengths of
channel bar by securing together in any convenient way such as by rivetting or
screwing or otherwise the two lengths bottom to bottom.
The upper or outer channel may be modified in form or section to suit flexible
tyres of any construction, for instance in some cases 1 may close inwardly the
sides so as to form a dovetailed groove and in other cases I may form a central
ridge and retain or dispense with the sides of the rim above the transverse web.
I may, sometinies, form the section so that the outer periphery is smooth and
three channels are formed upon the inner periphery, the central channel being
intended to grip the felloe or hoop of the wheel and the edges of the side channels
to grasp the edges of the flexible tyre which is suitably formed for the purpose.
In each case I join up the ends of the rim in the manner hereiubefore
indicated.
I do not confine myself to any particular form or section of special rim. I may
carry out the object of this invention and employ any suitable formation of the
outer periphery of the special rim.

I, WILLIAM BOWDEN of Barlow Range, Chorlton-cum-Hardy in the County
of Lancaster, Director, 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 more particularly to wheels to be fitted with pneumatic
and other flexible tyres such as solid or hollow cored india rubber, or composite
tyres, and consists in improvements in the construction of the rims or felloes of the
wheels for securing such tyres thereto and the invention is specially applicable to
ordinary wood wheele.
The objects of this invention are the improvements by which the following
advantages are obtained :-
When it is required to fit pneumatic or other elastic tyres to ordinary wood
wheels, by the use of my invention the removal of the ordinary iron hoop is
rendered unnecessary.
Also the necessity of having to shrink the metal rims upon wheels is obviated,
in cases where flexible tyres are employed. By the use of these improvements,
also, a wheel may be made lighter than when rims of metal and wood of ordinary
construction are used, as the metal part of a rim constructed according to my
invention is very strong or stiff and light.
In order that my invention may be more readily understood I have attached
hereunto a sheet of drawings to which I will now refer.
In the said drawings
Figure 1 represents a section of a wheel rim or felloe constructed in accordance
with my invention, and Figure 2 a peripheral portion of the same showing one
manner of joining the metal part of the rim or felloe.
Figure 3, represents a sectional view of the same pattern of the metal rim or
portion of felloe but of a modified construction.
Figures 4, 5, 6, 7, 8 and 9 represent also sectional views but of different patterns
of rims or felloes designed for several systems of means for securing elastic tyres to
the felloes.
Figure 10 is a sectional view of a similar pattern rim or felloe to that
illustrated by Figure 1 but formed by rolling or drawing from the solid bar.
Figure 11, represents in section a metal iim applied to the rim or felloe of a
wheel of ordinal y construction in which the metal hoop is retained.
As will be readily observed by reference to the drawings the improvements
indicate in each case a metal hoop formed so as to have an inverted channel which
is designed to contain or grasp the wood part of the wheel rim or in some cases the
ordinary metal hoops as well; and having the outer periphery of the hoop formed
and adapted in various ways to accord with the various systems of securing the
elastic tyres to the wheels.
In the several figures the metal part of the wheel or rim or felloe thereof is
indicated by the letter a and the wood rim or felloe or filling to which is secured
the spokes by the letter b.
In Figure 1 the metal rim a is shewn as made from a flat bar which is passed
through suitable rollers or dies and bent into the form indicated. A hoop
is formed by passing the bar through bending rolls; the ends may then be brazed
together or rivetted or otherwise secured together. Figure 2 represents a side
view of one method I prefer to use, according to which the ends of the hoop a¹ a¹
are squared and butted together. A plate a' is fitted preferably beneath the web
of the hoop and to this plate the ends of the hoop are secured by rivets, screws, or
bolts a which may pass through both metal and wood rims as shewn in Figure 2.

page_text: This method is specially applicable where these metal hoops are applied to already
built up wheels. In some cases especially when in building the wheel the rim or
felloe is to be completed first and the spokes and hub afterwards fitted the ends of
the metal hoop may be brazed and sometimes welded together. The wood rim or
filling made in segments is then placed in position in the inverted channel formed
in the hoop and the spokes fitted thereinto, after which the hub made in segments
or sections is secured in position. Figure 3 represents a sectional view of a similar
pattern rim to that shewn in Figure 1, but made in two parts by securing or
riveting or otherwise, one channeled bar upon another inverted channeled bar
in the manner shewn. Figures 4, 5, 6, 7, 8, and 9 represent sectional views of
rims or felloes constructed according to my invention, the channelled peripheries
of which are of well known forms and designed to carry tyres secured thereto
according to well known systems. Figure 10 represents a sectional view of a
rim or felloe made according to my invention and having a metal hoop of
H section produced by rolling the solid bar. Figure 11 represents a metal hoop
made and employed according to my invention, applied to a wheel having an
ordinary iron hoop which is retained. In this manner a wheel of ordinary
construction may be readily adapted to carry an elastic tyre, the hoop a in such a
case being made preferably of thin metal and with a joint similar to that shewn in
Figure 2.
I do not confine myself to the particular peripheral forms of the external hoop of
the rim or felloe shewn in the drawings. I so form this external or peripheral part
so as to adapt it to carry in each case any one particularly constructed tyre. The
internal surface of the metal hoop is formed as a channel in every case, preferably
as shewn in the several figures in the drawings but the sectional form of the
channel may slightly vary in some cases.
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 :-
:-
First. The construction of the rims or felloes of wheels for carrying pneumatic
and other elastic and flexible tyres or treads substantially as hereinbefore described
and illustrated in the accompanying drawings.
Second. The construction of a metal rim having an inner annular channel
seating and an outer or peripheral formation adapted to seat a pneumatic or other
elastic and flexible tyre or tread substantially as and for the purpose hereinbefore
set forth and illustrated by the drawings.
Third. The combination with a wheel having a cylindrical or approximately
cylindrical tread of an auxiliary metal rim having an internally channelled
surface and periphery formed or adapted to seat a pneumatic or other elastic
tyre or tread substantially as hereinbefore set forth and illustrated in the
drawings.
