    Look on talkingelectronics.com website and Google for Flip Flop

    That circuit looks like a two transistor oscillator.

    Note that this circuit produces a considerable reverse voltage on the base/emitter of the transistors. This was OK on the early pnp junction transistors but the newer epitaxial transistors should be limited to about 7V. At 9V you may be damaging them.

    A couple of diodes could be added to eliminate reverse current through the bases.
