as to permit the side ?ange to be slipped over
the felloe with the driving lug or plate I3 ar
be put in place beore the tire is applied, the
10 other side ?ange being put in place after the tire
is applied to the felloe, but before the tire is in
?ated. This permits the ?ange to be moved in
wardly toward the central plane of the felloe in
order that the locking ring I’! may be put in
place. It will be noted from an inspection of Figs.
1 and 3 that the locking rings have noses 20 adapt
ed to lie in an undercut portion of the groove I6
and portions 2! adapted to lie under the side
?anges l2. In order that the side ?anges will
not have their inward movement arrested too
soon, the recess I9 is madeof such a length as to
permit the side ?anges to move inwardly a suf
?cient amount prior to application of the locking
ring before the driving lug l3 strikes the end of
25 the recess. In other words, in assembling the
side ring the side ring is ?rst moved to the dotted~
line position in Fig. 3 and then the locking ring
ll slipped in place in the usual manner so that
the nose portion rests-within the groove I6, the
30 ends l8 of the lockingring being arranged on op
posite sides of the driving lug or plate I3. The
side ?ange i2 is then moved to the full-line posi
of this block could be formed by deforming a
form shoulders against which the ends of the
locking ring 25 will abut in case the ring tends to
shift peripherally. On the side ?ange I secure a
driving lug 29 by means of welding, such as 30, or
by any other suitable means, and this corresponds
to the lug E3 in Fig. 3. The driving lug is also
arranged between the ends of the locking ring
5 whereby the side ?ange is held against any
substantial peripheral movement. Instead of
having to form a recess, such as [9, in the ?rst
form of my invention illustrated, the rim may
be formed uniformly throughout its entire pe
riphery except that a lug, such as 21, is welded
in place therein to provide an abutment. The
edge of the rim, therefore, has a smooth appear
ance and there is less chance of dust and dirt
working in to the tire, not to mention the extra
strength given to the rim by having the periph
eral edge of the rim continuous instead of inter
rupted as in Fig. 3.

invention pertains may make various changes in 50

adapted to be arranged within said grooves, side
tire tool is inserted in the notch to lift the look

ner after the side ?ange hasbeen moved to the
dotted-line position shown in Fig. 3.
Of course, it will be understood that the felloe
is provided with a suitable slot for the recep
tion of the valve stem of the inner tube used in
the tire, as is customary in devices of this char
acter. It will also be understood that other means
may be used for securing the driving lug I3 to the
side ?ange without departing from the spirit and
scope of this invention and thatit could be made
of the same piece of material as the, side ?ange.
Furthermore, it will be obvious that the felloe
could be a rim which is to be applied to a wheel
instead of merely the felloe of the wheel itself,
as it is shown in the drawing.
In Figs. 5 and 6 there is showna modi?ed form
of my invention in which 23 represents the rim
and 24 the side ?ange. A locking ring 25 simi

lugs on said side ?anges arranged between the
ends of the respective locking rings to prevent
relative rotation between said locking rings and 60

into which said driving lugs project to prevent
relative rotation between said side ?anges and
felloe within certain prescribed limits.

groove adjacent one edge thereof, a side ?ange,
