  • Patent number: 5518104
    Abstract: A modular conveyor system includes modular conveyor units and modular transfer units, which are driven by the driveshafts from adjacent modules. The transfer units include a first driveshaft segment extending below the conveyor frame and first and second multi-direction wheels mounted on the shaft segment such that when the first driveshaft segment rotates, it drives the first wheel in a forward direction and the second wheel in a backward direction, the wheels being independently shiftable relative to the top surface of the conveyor frame so as to either convey a product or not convey a product.

  • Patent number: 5375696
    Abstract: The rollers of a live roller conveyor are driven by drive wheels, which are driven from a driveshaft extending along the conveyor. When the drive wheels and their respective conveyor rollers are in contact with each other, the drive wheels cause the conveyor rollers to rotate. When the drive wheels and conveyor rollers are out of contact, the rollers are not driven and can accumulate product. Relative motion between the drive wheels and the conveyor rollers causes the drive to be engaged and disengaged.

  • Patent number: RE36891
    Abstract: A conveyor has a drive wheel which is driven from a driveshaft and .[.which moves.]. .Iadd.relative motion between the drive wheel and conveyor roller causes movement .Iaddend.into and out of driving engagement. In the preferred embodiment, there is a drive gear mounted on the drive shaft, and the drive gear drives a drive wheel, which is mounted on a drive wheel mounting frame that pivots about the axis of the drive shaft, so that the drive wheel is constantly driven from the driveshaft and pivots into and out of driving engagement with the conveyor roller.
