Stationary Knife Patents (Class 460/52)
  • Patent number: 6872136
    Abstract: An ear of corn attached to a power driver such as a drill can be husked and or creamed in a two-step process without detaching the ear from the driver. The shelling device uses a spring-biased grater inside a tube to cut the kernels from the cob, and may be used alone or in combination with the husking device. If desired, the two devices can be connected using an ergonomically designed bracket and used sequentially.
