Abstract
Abstract The present invention is directed to a power mechanism that may be used for either absorbing or transmitting power; the invention being explained in terms of a motorcycle brake. It discloses a wheel structure in which the wheel-hub acts as a brake-drum, and a pair of separatable conical members is positioned internally of the hub, and acts as a continuous peripheral brake-lining.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
203 words
A power mechanism comprising: a cylindrical member adapted to rotate around a given axis; said cylindrical member having two differently-angled peripheral-surfaces; a first conical member mounted co-axially with respect to said cylindrical member; a second conical member mounted co-axially with respect to said cylindrical member; each of said conical members having angled peripheral-surfaces that are angled to correspond to one of said angled surfaces of said cylindrical member; slide-shaft means for mounting said conical members co-axially with said cylindrical member, for permitting said conical members to slide axially relative to each other; means for urging said conical members apart into a passive state; actuator means for urging said conical members toward each other into an activated state, for causing said angled peripheralsurfaces of said conical members to contact respective angled peripheral-surfaces of said cylindrical member; said actuator means comprising a first pivoted actuator adapted to move at least one of said conical members toward said other conical member; said actuator means comprising a second actuator; displacement means for axially displacing said first actuator relative to said second actuator; said displacement means comprising a plurality of ramps in one of said actuators, and a like plurality of complementarilyshaped grooves in the other said actuator.
Claim 2
Dependent Claim
203 words
A power mechanism comprising: a cylindrical member adapted to rotate around a given axis; said cylindrical member having two differently-angled peripheral-surfaces; a first conical member mounted co-axially with respect to said cylindrical member; a second conical member mounted co-axially with respect to said cylindrical member; each of said conical members having angled peripheral-surfaces that are angled to correspond to one of said angled surfaces of said cylindrical member; slide-shaft means for mounting said conical members co-axially with said cylindrical member, for permitting said conical members to slide axially relative to each other; means for urging said conical members apart into a passive state; actuator means for urging said conical members toward each other into an activated state, for causing said angled peripheralsurfaces of said conical members to contact respective angled peripheral-surfaces of said cylindrical member; said actuator means comprising a first pivoted actuator adapted to move at least one of said conical members toward said other conical member; said actuator means comprising a second actuator; displacement means for axially displacing said first actuator relative to said second actuator; said displacement means comprising a plurality of ramps in one of said actuators, and a like plurality of complementarilyshaped grooves in the other said actuator.
Claim 3
Dependent Claim
13 words
The combination of claim 1 including cable means for pivoting said first actuator.
Claim 4
Dependent Claim
197 words
A motorcycle brake comprising: a hub adapted to rotate around an axle; said hub having two differently-angled inner peripheral-surfaces in a double-cone configuration; a first conical member mounted co-axially with respect to said hub; a second conical member mounted co-axially with respect to said hub; each of said conical members having outer angled peripheral-surfaces that are angled to correspond to one of said angled surfaces of said hub; slide-shaft means, having a hexagonal periphery, for mounting said conical members co-axially with respect to said hub, for permitting said conical members to slide axially relative to each other; spring means for urging said conical members apart into a passive state; actuator means for urging said conical members toward each other into an activated state, for causing said outer angled peripheral-surfaces of said conical members to contact respective inner angled peripheral-surfaces of said hub; said actuator means comprising a first pivoted active-actuator adapted to move one of said conical members toward said other conical member; said actuator means comprising a second anchored-actuator that is rotationally-immobilized; displacement means comprising a plurality of ramps in one of said actuators, and a like plurality of complementarily-shaped grooves in the other said actuator.
Claim 5
Dependent Claim
197 words
A motorcycle brake comprising: a hub adapted to rotate around an axle; said hub having two differently-angled inner peripheral-surfaces in a double-cone configuration; a first conical member mounted co-axially with respect to said hub; a second conical member mounted co-axially with respect to said hub; each of said conical members having outer angled peripheral-surfaces that are angled to correspond to one of said angled surfaces of said hub; slide-shaft means, having a hexagonal periphery, for mounting said conical members co-axially with respect to said hub, for permitting said conical members to slide axially relative to each other; spring means for urging said conical members apart into a passive state; actuator means for urging said conical members toward each other into an activated state, for causing said outer angled peripheral-surfaces of said conical members to contact respective inner angled peripheral-surfaces of said hub; said actuator means comprising a first pivoted active-actuator adapted to move one of said conical members toward said other conical member; said actuator means comprising a second anchored-actuator that is rotationally-immobilized; displacement means comprising a plurality of ramps in one of said actuators, and a like plurality of complementarily-shaped grooves in the other said actuator.
Claim 6
Dependent Claim
25 words
The combination of claim 3 wherein said anchored-actuator and said slide-shaft are interlocked by said hexagonal periphery for rotationally-immobilizing said slide-shaft and said conical members.
Claim 7
Dependent Claim
20 words
The combination of claim 4 wherein said anchored-actuator is strapped to the frame of said motorcycle to achieve rotational immobilization.
Claim 8
Dependent Claim
17 words
The combination of claim 5 including cable means, attached to said active actuator, for pivoting said active-actuator.
Claim 9
Dependent Claim
18 words
The combination of claim 6 including a thrust-bearing positioned between said moved conical member and said active Actuator.
Claim 10
Dependent Claim
23 words
The combination of claim 7 including a wheel attached to said hub; whereby said hub acts as the brake drum for said wheel.
