5 circles

Given 3 points A, B, and C in a straight line and being the centers of 3 circles : The circle centered on B touches those centered on A and C.
Point O is the intersection between the straight line and a line tangent to all 3 circles.

The problem is to construct 2 more circles, such that the first touches the circles centered on A and B, and the second touches those centered on B and C, and the 2 new circles also touch each other.
The center line of the 2 new circles should also pass through point O.
Each circle should touch others externally. Hint     Details
