| What
makes a funhouse barrel roll? These photos afford an exterior
view of Whalom's Barrel of Fun never seen by patrons. The barrel
sits on a cradle of six grooved wheels affixed to two long shafts
mounted on bearing blocks on either side of the barrel. Narrow
support rims on the outer circumference of the barrel engage the
slotted drive wheels. On one side, an electric motor turns a large
roller-chain sprocket. This sprocket is connected to a counter-shaft
which reduces its speed and which, in turn, drives another chain
sprocket mounted to the main drive shaft. This shaft then turns
the drive wheels which transfer the motion to the barrel resting
upon them. |
