fiatable inner tube 12 and a casing 13, and
this cushion is fitted to the. seating member
6, in the manner shown in Fig. 1, and en-
tirely 'surrounds the said member. The
5 floating spoke rim, which compises. an ele-
inent of the rim section heretofore referred
to, is indicated at 14 and is disposed to sur-
round the pneuniatic cushion 13. Spokes 15
radiate from the said rim 14 and support the
10 outer rim 16 which carries the tire 17. In
order that the hub section comprising, gen-
erally speaking, the hub and the .casing
- plates, may be. connected with the rim sec-
tion just desribed, a number of sleeves 18
15 are arranged at intervalswithin the hollow
rim 14 and have their open ends secured in
any suitable manner in openings formed ini
the sidewalls of the said rim. Bolts 19 are
secured through the marginal portions of
20 the casing plates, and these bolts have re-
duced ends forming *shoulders 20 which
serve to properly space the said portions of
the said casing plates. The portions of the
bolts 19 which lie between the casing plates
25. constitute the supporting elements for the
buffer members, and the sleeves. 18 'consti-
tute the abutment elements.
In the form of the invention herein illus-
trated, the ,anti-friction bearing comprises
30 an inner sleeve 26 which is- both internally
and exteriorly cylindrical and an outer
sleeve 27 which iay be relatively thin and
which is continuously 'circumferentially cor-'
'rugated, the corrugations extending length-
.35 wise thereof. The soft rubber sleeve is indi-
cated by the numeral 28 and' in vulcanizing
the.same upon the sleeve 27, the rubber will
be forced into the corrugations . and some of
the rubber will enter or be forced through
40 perforations 29 which are formed in the cor-
rugated surface of the- sleeve 27, thereby
providing for a more firm anchorage, of the
rubber sleeve on the said sleeve 27..
It will be understood that the anti-fric-
45 tion sleeve is freely rotatable upon the.bolt
19 or any other support which may be pro-
vided 'and that, consequently, different por-
tions of the surface of the soft rubber buffer
sleeve will be successively -presented to the
50 wallof the abutment sleeve 18. It will fur-
ther be apparent that the rubber sleeve is not
directly mounted upon the bolt or other sup-
porting element and, consequently no por-
tion of the surface of the said rubber sleeve
55 is .subjected to rubbing contact and, even
should there be a relative shifting of the
buffer sleeve and abutment 'sleeve after the
two have initially been brought into contact'
with each other, no rubbing action will.occur
00 inasmuch as the buffer sleeve as a whole, or
more 'specifically the sleeve 26 is freely rota-
table upon the anti-friction bearing. It willfurther be understood that the sleeve 27 may
be readily removed from the sleeve 26 when
the rubber buffer sleeve has become worn '65
and it is desired to substitute a new one.
Having thus described the intention, what
is claimed as new is:
. 1. In a wheel of the class described, a hub
section and a -rim section, a cushion inter- 70
posed between 'the sections, a buffer carried
by one section and including a rotatable
sleeve, a corrugated sleeve fitted. thereon, a
yieldable sleeve surrounding the corrugated
sleeve, and an abutment carried-by the other 75
section for cooperation with the buffer
2. In a wheel of the class described, a hub
section and a rim section, a cushion inter-
posed between the sections, a buffer carried
by one section and including a rotatable 80
sleeve of anti-friction material, a corrugated
sleeve,'removably fitted, thereon and' formed.
with perforations, a sleeve of yieldable ma:
texial surrounding the corrugated sleeve and
the said material of the yieldable sleeve en- 85
tering the said perforations in the corru-
gated sleeve, and an abutment carried by
the other section' for coperation with the
buffer.
3. In a wheel of the class described, a hub 90
section and .a rim section,: a cushion 'inter-
posed between the sections, a buffer carried
by one section and including a "rotatable.
sleeve, a corrugated sleeve removably fitted
thereon, a. yieldable sleeve 'surrounding the 95
corrugated sleeve, and an abutment carried
by the other section for. cooperation with
the buffer the corrugations 'of the second
mentioned sleeve extending longitudinally
of the said sleeve. 100
4. In a wheel of the class described, a hub
section and 'a rim section,' a cushion inter
posed between the sections, a buffer carried
by one section and including a rotatable
sleeve, a sleeve fitted thereon and having an "10'
irregular exterior surface, a yieldable' sleeve
'surrounding the second mentioned sleeve
and interiorly, conforming to the outer sur-
face; and an abutment carried by the outer
section for cooperation with the buffer. 110
5. A wheel buffer of the 'class described,,
comprising 'a sleeve interiorlyy cylindrical, 'a
corrugated sleeve fitted thereof, and' a yield-
able 'sleeve .surrounding the corrugated
sleeve. 115
6. A wheel buffer of the class described,
comprising a' sleeve interiorly cylindrical, a
corrugated perforated sleeve removably fit-
ted thereon, and a. sleeve of yieldable mate
vial surrounding the corrugated sleeve, the 120
material of the yieldable sleeve entering the
said perforations in the corrugated sleeve.
In testimony whereof Laffi ny signature.
