ABSTRACT:
A random number generating device for randomly selecting one of a plurality of suspendable balls which are stirred and circulated in a chamber by an upflowing fluid stream. Upon termination of fluid flow one of the balls falls downwardly through a relatively narrow bottom trough into a lower pocket having a transparent wall. The device is provided with steeply sloping inclined facing sidewalls flaring outwardly from said trough and sufficiently steep so that upon termination of fluid flow non-selected balls are out of contact with the selected ball as it falls from the trough into the pocket. Thereby, any jamming of non-selected balls occurs at an elevated level and does not prevent a single, randomly selected ball from entering the pocket at the end of each cycle.
