This invention relates to vehicle wheel rimsof
“the character employing a gutter at one edge
thereof and a detachable tire retaining ?ange in
‘
the form of an endless ring mounted in the gutter.
5 ‘The principal object of this invention is the pro
?ange E3 in the gutter i2. ‘ This consists in
swedging or cutting away a portion of the inner
edge of ?ange it ‘to provide a relief i8 of limited
vvision of'a novel gutter and side ?ange construc
tion permitting the mounting and demounting of
is provided with a demounting slot or recess IQ
for the reception of a prying tool. While the slot

ernal diameter of the ?ange is less than the dis

is is located substantially diametrically opposite
from the relief l8, it is intentionally located ap
proximately 12 degrees from a point i811 directly 10
opposite therelief i8 on the center line i8a of
relief 18. As here shown, the slot i9 is located in

clination is of importance, although they may be
varied to some extent. Preferably the surface
indicated at lQa is inclined approximately 60
degrees from a vertical plane. ‘The extent of
the radial inclination of recess i9 is preferably

The relation of the several parts of the rim
35 embodying the present invention is best shown
mately 78 degreeswith the radius of the ?ange.
The importance of these inclined surfaces for
slot i 9 will appear from the following description
of the manner in which the ?ange is mounted
upon the rim.
The manner of mounting the ?ange I3 upon
the rim H3 is illustrated in Figures 5, 6 and 7.
As shown in Figure 6, the inner edge of ?ange
i3 lying below the relief is and the slot i9 is in- ‘
serted into the gutter l2 which, as will be under 35
in Figure 3. ‘As there shown, the rim includes
stood, may be readily accomplished notwith
an annular tire seat Ii] having an integral tire
standing the difference between the diameter of
the ?ange and the gutter. As soon as the lower
portion of ?ange i3 is inserted in the gutter i2
anyconventional form of prying tool is applied to
the slot i9 and pressure exerted against the ring

?ange i3 is mounted in the gutter I2.
The heels M of a pneumatic tire are shown in
the position occupied when an in?ated tire is
mounted upon the rim. Conventionally the rim
45 I0 is secured to the periphery of a wheel body l5
it in a radial and circumferential direction.
This pressure stretches the ?ange out of round
and pulls the lower half ?rmly into the gutter so
by means of rivets l6, the parts l5 and i6 being
shown in dotted lines.
The detachable tire retaining ?ange i3 is in
is pulled over the outer wall of the gutter. As
soon as the ?ange i3 adjacent the slot I9 is over
the gutter wall 92a. the remainder of the ?ange
may then be readily pressed into position be
cause of the fact that the major portion of the
?ange is already deep in the gutter. 7
Figures 5, 6 and '7 show the relative positions
of the ?ange and gutter as the prying tool is
applied to the slot 89. The lower portion of
?ange I3 is engaging the bottom of gutter l2 as
the form of an endless ring and its internal di
ameter at the points ll--I1 is less than the dis
tance from the top of the gutter wall Hot at one
side of the rim ii) to the bottom of the gutter l2
at the diametrically opposite side of the rim. In
view of this difference in diameters special pro
55 vision is made for mounting and demounting
that the portion of ?ange i3 adjacent the slot 19 45

shown in Figure 6 while the upper portion of
?ange I3 is still located outside of the gutter.
Of course, the internal diameter, of the ?ange
I3 is greater than the internal diameter of the
gutter l2 measuring from the bottom of the gut
inner edge of the ?ange in a region remote from
the relief to provide an inclined contact surface,
one circumferential extremity of the contact sur
face being more remote from the center of the
?ange than the other circumferential extremity.
ter at one side of the rim to the bottom of the
gutter at the diametrically opposite side of the
rim. Consequently, when mounted as just de
having a gutter at one edge thereof, a tire retain
ing ?ange in the form of an endless ring mounted
scribed, the ?ange I3 is loosely seated in the gut
in the gutter, the internal diameter of the ?ange
10 ter and out of contact with the bottom of the
gutter throughout a substantial part of the cir
cumference.
The
?ange ‘ is
not permanently
seated in the gutter as a locking and supporting
?ange for a tire until a pneumatic tire has been
in?ated upon the rim Hi. When a tire is in
?ated on the rim the heel portions 14 of the tire
assume the positions illustrated in Figure 3 and
cause the ?ange l3 to take the position also il
lustrated in that ?gure. In other words, the
20 ?ange I3 is seated upon the inner surface of side
wall [2a of gutter I2 by the pressure which the
in?ated tire exerts against it.

a single relief of'limited circumferential extent

of the relief, the circumferential extremity of
the mounting slot farthest from the relief being
more remote from the center of the ?ange than
the circumferential extremity of the slot nearest 1.
to the relief.

vention has been herein shown and described, it

limited thereto, but is co-extensive with the scope
of the appended claims‘
45
I claim:
1. A wheel rim comprising an annular tire seat
having a gutter at one edge thereof, a tire re
taining ?ange in the form of an endless ring
mounted in said gutter, the internal diameter of
the ?ange being less than the distance from the
top of the gutter at one side of the rim to the
bottom of the gutter at the diametrically oppo
site side of the rim, said ?ange provided with
means for mountingand demounting the same
consisting of a single relief of limited circumfer
ential extent and a mounting slot formed in the
remote from the relief, one circumferential ex
tremity of the mounting‘ slot being more remote
from the center of the ?ange than the other ex
tremity, and one axial extremity of the mounting
slot being more remote from the center of the
?ange than the. other axial extremity.
4. A wheel rim including a tire retaining ?ange
in the form of an endless ring having a relief
and a mounting slot of limited circumferential
extents formed in its inner edge, the slot being
located in a zone spaced more than 145 degrees
and less than 180 degrees from the center of the
relief, the circumferential extremity of the slot
which is remote from the relief being more remote ,
from the center of the ?ange than the extremity
adjacent the relief to provide. an inclined con
tact surface between the two circumferential ex
tremities of the slot having an inclination form
ing an acute angle of substantially less than 90 .
degrees with a radius of the ?ange passing
through the remote circumferential extremity of
the slot.
