Claims Analysis

Total Claims: 23
Claim 1
Independent Claim 106 words
In a drive arrangment for a rotating unit, such as a rotary kiln, a drum mill, or the like having a main motor, a main transmission unit arranged between the main motor and the unit to be driven, an auxiliary motor, an auxiliary drive transmission unit arranged between the auxiliary motor and the main transmission unit, a centrifugal brake arranged between the auxiliary motor and the main transmission unit, and an overriding clutch rotatable in each of two opposite directions for overriding the auxiliary drive, the improvement comprising a shift clutch engageable with the overriding clutch for arresting the overriding clutch in both directions of rotation.
Claim 2
Dependent Claim 106 words
In a drive arrangment for a rotating unit, such as a rotary kiln, a drum mill, or the like having a main motor, a main transmission unit arranged between the main motor and the unit to be driven, an auxiliary motor, an auxiliary drive transmission unit arranged between the auxiliary motor and the main transmission unit, a centrifugal brake arranged between the auxiliary motor and the main transmission unit, and an overriding clutch rotatable in each of two opposite directions for overriding the auxiliary drive, the improvement comprising a shift clutch engageable with the overriding clutch for arresting the overriding clutch in both directions of rotation.
Claim 3
Dependent Claim 32 words
