Thrill of looping: the latest ride of 1934

From the June, 1934 issue of Modern Mechanix, this squib on a new carny ride that had debuted in LA, that supplied "the thrills of looping."
A car resembling the cockpit of a plane is supported on a hollow steel tube which pivots on a large ball bearing mechanism at the top of its steel frame.

The device is powered by a small electric motor which swings the car back and forth, gradually increasing the arc until enough momentum is developed to carry it over the top.
