The Iowa Agriculturist
Threshing and Husking
After grain and corn had been harvested, the farmer had to thresh or
shell it. Threshing is the process of removing the grain from the heads.
Shelling is the removal of the kernels from the ears.
The job of threshing was done by beating the grain out of the heads of
the plant. The farmer or thresher would use a short wooden club attached
to a long handle with a piece of leather. Obviously, this was hard work
and required additional labor to separate the grain from the chaff.
In the late 1700's people invented horse-powered threshing machines to
reduce the workload.
In 1837 Hiram A. and John A. Pitts of Maine developed a
highly improved thresher. Their machine threshed the grain from the heads,
separated the straw by a blower, and removed the chaff from the grain
in a single operation.
These newer threshers required a crew of people to operate.
Later, steam threshers replaced the horse-powered threshers. They required
an engineer and at least fifteen other people. Horse-drawn wagons hauled
the grain to and from the thresher. Threshing was a neighborhood operation
because of the large number of people it required.
Eventually, in the Great Plains and Far West, a harvester-thresher,
or combine, was developed. This greatly reduced the job of harvesting
the grain and separating it from the rest of the plant.
In the mid-1800's inventors were also coming up with easier
ways of removing the ears of corn from the stalks, stripping the husks,
and grinding them into feed called fodder. Most of the husker-shredders
worked the same way. Stalks of corn were fed into a roller, which snapped
off the ears. The stalks were then pushed through a series of knives and
smashed. The shredded fodder then fell into a blower, which passed it
through a funnel and out of the machine onto the stack. The ears dropped
from the snapping rollers to the husking rollers. Kernels that were removed
by the husking rollers fell through a screen, where a fan blew away dirt
particles before the grain fell into a box under the machine.
Both the threshing and husking machines were important farm
equipment. They made possible increased yields from farmers' fields while
reducing the amount of labor.
