PROVISIONAL SPECIFICATION.
Improvements in Rims or Felloes for Cycles and other Vehicles.
I, JOHN HENRY BALL of 65 Queen's Walk, Nottingham Engineer do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to make rims or felloes of greater lateral strength
than has hitherto been done, and especially for such rims as are intended for use
with inflated or other tyres which exert a side strain upon the channel of the rim.
By my improved method I construct a rim of one or more strips or bands of
metal treated so as to form a tubular edge or bead on or in each side thereof this
bead being generally in turn sustained by the sides of a strip or band rolled or
grooved to form an arched support thereto by brazing or other suitable process.
The channel may be grooved either longitudinally or crosswise but I prefer that it
should be straight to resist side-strain. The position of the beads and the thickness
of the strip or band may be varied to suit the necessities of wheel-making.
In some cases I take an ordinary hollow rim or such as is described in Letters
Patent No. 14890, 1889, and form the side or the channel as the case may be with
tubular or grooved beads therein, which may or may not be secured by brazing or
otherwise. The beads may be circular or of any other desired form in cross-
section, the metal thickened or folded to form a suitable bed in one or more places
for the spoke heads to rest upon. The rim may be made by any suitable process
now extant and its cross-section may be varied as required to suit the requirements
of any special form of tyre.

COMPLETE SPECIFICATION.
Improvements in Rims or Felloes for Cycles and other Vehicles.
I, JOHN HENRY BALL, of 65 Queen's Walk, Nottingham Engineer, 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 :-
The object of this invention is to make rims or felloes of greater lateral strength
than has hitherto been done and especially such rims as are intended for use with
inflated or other tyres which exert a side strain or wedge action upon the channel
of the rim.
According to my invention I construct a rim of one or more strips or bands of
sheet metal (which may be endless if desired) treated so as to form a tubular or
grooved bead on or in each side thereof, these beads being in turn sustained by the
sides of a strip or band rolled or grooved to form an arched support thereto, by
brazing or other suitable process. The chaunel may be grooved either longitudinally
or crosswise but I prefer that it should be straight to resist side-strain. The
position of the beads and the thickness of the strip or band may be varied to suit
the necessities of wheel-making.
In some cases I take an ordinary hollow rim, or such as is described in Letters
Patent No. 14890 of 1889, and form the sides or the channel as the case may be

page_text: with tubular or grooved beads therein, which may or may not be secured by brazing
or otherwise. The beads may be circular or of any desired form in cross section,
and the strip on which the spoke heads rest is thickened in any suitable manner.
The rim may be made by any of the known processes and its shape in cross section
may be varied as required to suit the type of tyre it is intended to carry.
In order that my invention may be fully understood I will more particularly
describe it making reference to the accompanying drawing in which the figures are
views in transverse section illustrating some methods of carrying my invention
into practical effect, similar parts being marked with like letters of reference
throughout the several views.
My improved wheel rim may be made out of one or more strips or bands of
sheet metal according to any of the well-known methods of construction. When
I make the rim out of one strip or band I form the circumferential beads A, A,
while the strip of metal is being fashioned to give the strip the desired shape in
cross section. When these rims are intended to carry tyres of the "1893 Dunlop
type the beads A, A, are formed on the concave face of the rim to form the
necessary shoulders a,c, as shown by Figure 8, but when they are intended to
carry tyres of the "Seddon" type which require no shoulders in the rim the
beads A, A, are formed either on the inner or outer face of the rim and lie in the
hollow thereof as shown by Figure 9. In both cases the part C between the beads
forming the bottom of the groove of the rim is straight.
When the wheel rim is made out of two strips of metal the one is shaped to
form the outer shell B, and the other the inner part C forming the bottom of the
groove of the rim. In this construction the circumferential beads A, A, may either
be formed on the inner part C as shown by Figures 1, 2, 5 and 6, or on or by the
outer shell C as shown by Figures 3, 4, and 7. Dealing with the former
construction, if the rims are intended to carry tyres of the "1893 Dunlop" type
the beads A, A, are formed on the outer face of the strip C as shown by
Figures 1, 2, 5 and 6 to form the necessary shoulders a, a, but in rims adapted to
carry tyres which do not require such shoulders the beads are preferably formed
on the underside of the strip C as shown in dotted lines in Figure 5. In the
construction shown by Figure 6 the edges of the outer shell B are turned inwards
to adapt it to carry tyres of the "Clincher" type.
In the construction in which the circumferential beads A, A, are formed on or by
the outer shell B, the inner part C takes the form of a straight strip. When the
rims are adapted to carry tyres which require shoulders x, x, the beads A, A, are
formed as shown by Figures 4 and 7, but when the rims are adapted to carry tyres
which do not require the shoulders in the rim the beads A, A, may be formed by
making depressions in the outer face of the shell B as shown by Figure 3, or the
strip C may be placed outside the beads A, A, as shown by dotted lines in
Figure 4.
Figures 10, 11 and 12 illustrate specific types of rims constructed according to
my invention.
It will be understood that the circumferential tubular or grooved beads A, A,
may be of any desired form in cross section and that in all cases they are fixed to
the adjacent parts of either the outer shell B or of the inner strip C, as the case may
be, by brazing or by any other suitable process, so that all parts of the rim are
firmly secured together thus making a laterally stiff, strong, and at the same time
light wheel rim which has no tendency to open out due to the side strain exercised
by the pressure within the tyre.
I wish it to be particularly understood that I do not limit myself to the precise
details of construction herein before described and illustrated by the accompanying
drawing, but that I hold myself at liberty to make such changes and alterations as
fairly fall within the spirit and scope of my invention.
I am aware that wheel rims have already been made with tubular beads at thei
outer edges and I do not therefore claim the use of tubular beads broadly, but
