The Water Wheel
The water wheel,
including the forebay and chute, was
manufactured by Fitz Water Wheel Company. It
was installed sometime around 1906 to replace
the wooden water wheel by owner Allen Simmers.
The water wheel
was restored in 2001-2002 by Pottstown Metal
Welding Company, under the direction of Jack
Brogan and Stephen Kindig. The spokes and shaft
are original while the buckets were replicated. It
was assembled in 8 sections.
It is an overshot
type water wheel, as opposed to breast shot,
undershot or pitch back type.
The water wheel is
16 feet 4 inches in diameter and weighs
approximately 3,500 lbs. It contains 48 buckets, each holding approximately
5.8 gallons of water.
The water wheel
turns at 8 rpm.
The water wheel
has almost 6400 foot pounds torque!!
The water wheel
developed 9-14 horsepower at 8 rpm.
The water flow
required at full power at 8 rpm is approximately
2000-3000 gallons per minute.
The water wheel
was designed to be compatible with the existing
wooden gear system.
The end of chute
is positioned approximately 9 inches before top
dead center. The chute delivers water evenly
across the width of the buckets.
The buckets were
carefully designed to minimize spillage, and
retain water all the way down to the tail race.
A hole in each bucket reduces the vacuum to
empty the water as quickly as possible.
The forebay
(header tank) was also replicated by the
Pottstown Metal Welding Company. It holds
286 gallons of water when completely filled.
Practically speaking, we would never have it
filled more than one-half to two-thirds of
this. The forebay measures roughly 3 feet x 3
feet x 4 ½ feet and weighs 600 lbs empty. It weighs
1800 lbs half-full of water.
The forebay
control gate regulates the flow of the water
through the chute onto the wheel.
Very
little water is required to turn the wheel
without turning the stones
The pipe diameter
leading into forebay is 18”.
