I've drawn up a schematic...

I've changed the supply to 2x C batteries, and added a diode in
parallel to the motor.

Do you think this would work?

Two other things you left out the connection between pin four and the
positive supply rail, both drawings, and it is good practice to put a
cap between pin five and ground to keep the timing stable
