Abstract
Abstract A torque converter of the mechanical type for transmitting power from power means such as a motor to a driven member from which power take-off may be obtained which includes a rotatably mounted ring gear for rotation by the motor having teeth engagable with a drum having a cam groove rotatably mounted on the driven member with one or more weights being guidably mounted on the driven member and engagable with the cam groove so that rotation of the drum by the ring gear moves the weights in a reciprocating manner at a speed proportional to the speed of the ring gear so as to impart periodic inertial forces to the driven member for smoothly transmitting torque from the motor to the driven member throughout the entire speed range from rest to full speed.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
99 words
A torque converter for use with associated power means comprising, in combination, a rotatably mounted driving member, means for connecting said driving member to said associated power means, a rotatably mounted driven member, inertia means rotatably mounted on said driven member, interconnecting means on said driving member and said inertia means for rotating said inertia means and said driven member, said inertia means including weight means guidably mounted on said driven member for reciprocating movement during the rotation of said inertia means at a speed directly proportional to the rotational speed of said inertia means by said driving member.
Claim 2
Dependent Claim
99 words
A torque converter for use with associated power means comprising, in combination, a rotatably mounted driving member, means for connecting said driving member to said associated power means, a rotatably mounted driven member, inertia means rotatably mounted on said driven member, interconnecting means on said driving member and said inertia means for rotating said inertia means and said driven member, said inertia means including weight means guidably mounted on said driven member for reciprocating movement during the rotation of said inertia means at a speed directly proportional to the rotational speed of said inertia means by said driving member.
Claim 3
Dependent Claim
62 words
A torque converter in accordance with claim 1 wherein said inertia means comprises at least one cylindrical member rotatably mounted on said driven member and wherein said interconnecting means include means for drivably interconnecting said driving member and said cylindrical member having a continuous peripheral groove for moving said said guidably mounted weight means reciprocally during the rotation of said cylindrical member.
Claim 4
Dependent Claim
32 words
A torque converter in accordance with claim 2 wherein the axis of rotation of said cylindrical member is arranged in substantially parallel relationship with the axis of rotation of said driven member.
Claim 5
Dependent Claim
37 words
A torque converter in accordance with claim 3 including a plurality of said cylindrical members on said driven member and wherein said plurality of cylindrical members are drivably interconnected by said interconnecting means to said driving member.
Claim 6
Dependent Claim
27 words
A torque converter in accordance with claim 3 wherein said interconnecting means comprises gear means on said driving member and said cylindrical member arranged in meshing engagement.
Claim 7
Dependent Claim
91 words
A torque converter in accordance with claim 5 including guide means on said driven member adjacent said cylindrical member and extending in substantially parallel relationship with the axis of rotation of said cylindrical member and said driven member, and wherein said weight means include a pair of weights arranged in said guide means adjacent the periphery of said cylindrical member and in diametrically opposed relationship therewith, said weights being slidingly engageable with said continuous peripheral groove for said reciprocating movement in said guide means during the rotation of said cylindrical member.
Claim 8
Dependent Claim
77 words
A torque converter in accordance with claim 6 wherein said associated power means comprises a motor having an output shaft and including a first differential gear, a pair of wheels connected to said first differential gear, means for drivably connecting said driven member to said first differential gear and wherein said means for connecting said driving member to said associated power means comprises a second differential, and means for connecting said second differential to said driven member.
