Abstract
Abstract A wheel balancing device for permanent wheel attachment. A rim of the device acts on the wheel periphery to confine same against vibrational movement. A hub and conical disc when acted on by centrifugal force during wheel rotation move axially toward the wheel to radially load the rim and displace same into forceful contact with the wheel periphery.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
99 words
A wheel attachable balancing device comprising in combination, radially expansible means for disposition proximate a circular portion of a wheel and radially displaceable during wheel rotation into engagement with said circular portion, a hub, hub support structure carried by said expansible means and locating said hub in coaxial offset relationship with said expansible means, the entire body of said hub being axially displaceable during wheel rotation by centrifugal force acting on said support structure, said support structure biasing said radially expansible means during wheel rotation into contact with the circular portion of the rim to counteract vibratory wheel motion.
Claim 2
Dependent Claim
99 words
A wheel attachable balancing device comprising in combination, radially expansible means for disposition proximate a circular portion of a wheel and radially displaceable during wheel rotation into engagement with said circular portion, a hub, hub support structure carried by said expansible means and locating said hub in coaxial offset relationship with said expansible means, the entire body of said hub being axially displaceable during wheel rotation by centrifugal force acting on said support structure, said support structure biasing said radially expansible means during wheel rotation into contact with the circular portion of the rim to counteract vibratory wheel motion.
Claim 3
Dependent Claim
19 words
The device claimed in claim 1 wherein said expansible means is a continuous rim radially expansible into wheel contact.
Claim 4
Dependent Claim
20 words
The device claimed in claim 2 wherein said rim carries wheel engaging spring biased teeth adapted to provide wheel contact.
Claim 5
Dependent Claim
14 words
The device claimed in claim 1 wherein said support structure is of conical configuration.
Claim 6
Dependent Claim
19 words
The device claimed in claim 4 wherein said support structure is segmented and comprised of individual sector shaped members.
Claim 7
Dependent Claim
38 words
The device claimed in claim 1 wherein said support structure is of conical configuration, said hub and said support structure moving toward a plane containing the expansible means during wheel rotation to bias same radially into wheel contact.
Claim 8
Dependent Claim
43 words
The device claimed in claim 6 additionally including a retainer assembly including a spider attachable to the wheel lug bolts and including a retainer to confine the hub against lateral movement in the event of separation of the present device from a wheel.
Claim 9
Dependent Claim
20 words
The device claimed in claim 7 wherein said retainer assembly includes a retainer plate and a plurality of spider arms.
Claim 10
Dependent Claim
30 words
The device claimed in claim 8 wherein said retainer plate is adapted to mount a variable number of legs to accommodate attachment to both four and five lug bolt wheels.
Claim 11
Dependent Claim
18 words
The device claimed in claim 8 wherein said retainer assembly includes a retainer extending outwardly past the hub.
