When did alexander graham bell invent the wheat husker?

Alexander Graham Bell did not invent the wheat husker; he is best known for his invention of the telephone in 1876. The wheat husker, a machine for removing the husks from wheat, was developed by various inventors in the 19th century, but Bell's contributions were primarily in telecommunications and related fields. If you're looking for information on agricultural machinery, other inventors like Hiram Moore played significant roles in that area.
