Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
121 words
A roller conveyor having a plurality of rollers rotatably mounted to define a pass line for articles conveyed by said conveyor, a flexible line drive shaft rotatably mounted adjacent said rollers and extending longitudinally of said pass line, a magnetic coupling and a drive belt for coupling each of said rollers to said drive shaft for limited-torque rotation thereby, said conveyor being a curved section having said conveyor rollers disposed in an arcuate array, means for extending said drive shaft in a generally arcuate configuration along said curved section, said extending means including an arcuate array of bearing members in which said shaft is maintained by means of said drive belts, said bearing members being shaped to receive said flexible shaft.
Claim 2
Dependent Claim
121 words
A roller conveyor having a plurality of rollers rotatably mounted to define a pass line for articles conveyed by said conveyor, a flexible line drive shaft rotatably mounted adjacent said rollers and extending longitudinally of said pass line, a magnetic coupling and a drive belt for coupling each of said rollers to said drive shaft for limited-torque rotation thereby, said conveyor being a curved section having said conveyor rollers disposed in an arcuate array, means for extending said drive shaft in a generally arcuate configuration along said curved section, said extending means including an arcuate array of bearing members in which said shaft is maintained by means of said drive belts, said bearing members being shaped to receive said flexible shaft.
Claim 3
Dependent Claim
