Abstract
Abstract The vibration dampening assembly effectuates an automatic dynamic balancing technique for rotating masses operating at all circumferential speeds and maintains the weight members in their balance position when the assembly is not rotating. The vibration dampening assembly includes an annular retaining means adapted for attachment to a rotating mass. Weight means are movably disposed in the retaining means. Biasing means are located in the retaining means to provide a sufficient amount of force to hold the weight means in place against the pull of gravity within and with respect to the retaining means. However, the force of the biasing means is not effective to overcome the movement of the weight means within and with respect to the retaining means upon rotation of the assembly. Various features of the invention are directed to the specific type of biasing means and weight members used within the retaining means.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
169 words
A vibration dampening assembly for a rotatable mass comprising: a. an annular retaining means adapted for attachment to a mass which rotates about an axis of rotation, b. weight means movably disposed in the retaining means, and c. at least one continuous ring member located in the retaining means and being disposed between the inside surface of the retaining means and the weight means so that the weight means is located between the axis of rotation and the ring member, d. said ring member being composed of a resilient material and in direct contact with the weight means so that the weight means acts against the resilient ring member when the mass is rotated, e. said resilient ring member providing a sufficient amount of force to hold the weight means in place against the pull of gravity within the retaining means when the mass is not rotated but not being effective to overcome movement of the weight means with respect to the retaining means upon rotation of the assembly.
Claim 2
Dependent Claim
169 words
A vibration dampening assembly for a rotatable mass comprising: a. an annular retaining means adapted for attachment to a mass which rotates about an axis of rotation, b. weight means movably disposed in the retaining means, and c. at least one continuous ring member located in the retaining means and being disposed between the inside surface of the retaining means and the weight means so that the weight means is located between the axis of rotation and the ring member, d. said ring member being composed of a resilient material and in direct contact with the weight means so that the weight means acts against the resilient ring member when the mass is rotated, e. said resilient ring member providing a sufficient amount of force to hold the weight means in place against the pull of gravity within the retaining means when the mass is not rotated but not being effective to overcome movement of the weight means with respect to the retaining means upon rotation of the assembly.
Claim 3
Dependent Claim
49 words
An assembly as defined in claim 15 wherein there are two ring members disposed on the inside surface of the retaining means and being laterally displaced With respect to each other, said weight means being movably disposed between the inside surface of the retaining means and the ring members.
Claim 4
Dependent Claim
23 words
An assembly as defined in claim 1 wherein said retaining means includes means for attaching the dampening assembly onto a vehicular wheel assembly.
Claim 5
Dependent Claim
31 words
An assembly as defined in claim 1 wherein said retaining means includes a beveled hub portion having a structural configuration to fit against the brake drum of a vehicular wheel assembly.
Claim 6
Dependent Claim
29 words
An assembly as defined in claim 1 wherein said retaining means includes a hub portion having a slot configuration to fit over the studs of a vehicular wheel assembly.
Claim 7
Dependent Claim
30 words
An assembly as defined in claim 5 wherein said slot configuration includes a plurality of slots extending at a transverse angle with respect to the radius of the wheel assembly.
Claim 8
Dependent Claim
131 words
A vibration dampening assembly for a rotatable mass comprising: a. an annular retaining means having an outer flange portion and an inner flange portion forming an annular channel, b. said annular retaining means being adapted for attachment to a rotatable mass, c. weight means movably disposed in the retaining means, and d. at least one continuous ring member disposed inside the channel against the outer flange portion and acting directly against said weight means, e. said ring member being resilient and effective to provide a frictional force that holds the weight means in place when the mass is not rotating and is countered by the action of the centrifugal force on the weight means when the retaining means is rotating so that the weight means will move to a balance position.
Claim 9
Dependent Claim
131 words
A vibration dampening assembly for a rotatable mass comprising: a. an annular retaining means having an outer flange portion and an inner flange portion forming an annular channel, b. said annular retaining means being adapted for attachment to a rotatable mass, c. weight means movably disposed in the retaining means, and d. at least one continuous ring member disposed inside the channel against the outer flange portion and acting directly against said weight means, e. said ring member being resilient and effective to provide a frictional force that holds the weight means in place when the mass is not rotating and is countered by the action of the centrifugal force on the weight means when the retaining means is rotating so that the weight means will move to a balance position.
Claim 10
Dependent Claim
155 words
In a vehicular wheel assembly, the combination comprising: a. an annular vibration dampening assembly fixedly attached about the axis of rotation of the vehicular wheel assembly, b. said dampening assembly including an annular retaining means, weight means movably disposed in the retaining means, and at least one resilient continuous ring member located in the retaining means, c. said annular retaining means having an outer flange portion and an inner flange portion forming an annular channel, d. said resilient ring member being disposed inside the channel against the outer flange portion, e. said resilient ring member providing a sufficient amount of frictional force to hold the weight means in place against the pull of gravity within the retaining means when the mass is not rotating and is countered by the action of the centrifugal force on the weight means when the retaining means is rotating so that the weight means will move to a balance position.
