The present invention pertains to a wheel
behind the annular portion when it is desired to
structure and more particularly to a novel ar
pry the cover free of the wheel. ‘

Other objects and features of this invention
will more fully appear from the following detailed
description taken in connection with the accom
panying drawing which illustrates a single em-.
bodiment thereof and on which:
Figure 1 is a side view of a Wheel structure
embracing either or both a trim ring and a hub
cap.
An object of this invention is to provide a sim
pli?ed form of wheel trim retaining means.

Another object of the invention relates to the
provision of retaining means of such character
that the same may become part of the wheel
without necessitating its removal each time the

‘In view of the desire of automotive engineers to
reduce to‘a' minimum the unsprun'g weight of an
automobile‘ wheel, I have found‘ it very desirable
to make‘ my wheel cover‘ [4; or‘ at lea-‘st the'trim'
part It, of a light, plastic material; I have at
tained excellent results in the use of‘ a thermo
plastic material known‘ in‘ the trade as “ethylcel
lulose‘.” _By making” the trim~ ring It‘ of‘ such a
material which is self-sustaining‘in‘ form and yet
highly resilient, it"is possible to'provide‘the't'rim
ring" with‘ the necessary resilient characteristics
whereby its outer peripheral or‘lipv portion l8 may

away from the tire as‘ shown inv Figure 3 for‘ the
purpose of affording access to'the‘ rear side‘of
the same. This access may be'for the‘purpose of
getting to the valve stem or as shown in‘ Figure 3'
may be for the purpose of enabling" the'introduc

While it is to be ‘understood that the" hub can

plastic material, I have also attained excellent re";
"sults by making this hub‘cap of a light metallic
sheet material which enables theprovision of the

' as-the number of ?ngers provided’ are suf?cient
to properly retain the cover‘ on‘ the wheel. Also;
it should be noted from Figures 1 and 2 that the
body part 22 of the retaining ring l5 overlies the

such openings should it'be desirable not to per
mit the circulation of air therethrough. ‘This
would be advantageous rfromjthe standpoint of
preventing the accumulation of dirt and other
material behind the trim ring it. In some cases
it is possible to cover the openings l2 and this is
particularly true where the brake drum attached
to the wheel is adequately ventilated. The'br'ake
drum is not shown, however, since it‘ is" of av con
ventional construction and is now well known in
the'art' as is evidenced'by the many patents gran't‘—‘
