Four Station Roundabout Fairground Ride
This model is based upon a 12½” square base, with the mechanism built upon this.
It is powered by a Dave Taylor-supplied electric motor driving reduction gearing to two motions.
The first motion rotates the roundabout about the central column turning the four arms with it. This central column is mounted on a 4” ball race, with a 133-tooth gear on the upper side, driven by the reduction gears below.
The second motion operates through the central rod which the arms rotate, this rod rod drives a cam on its extremity, an offset pair of stacked wheel discs is attached to each of the four arms by rods and end bearings. As the cam rotates the arms lift up and fall. This is geared slower than the first motion.
Each arm has a passenger seat and a barrier to prevent them falling out.
