That's a jolly complicated mechanism I wonder what advantages it was supposed to have over a more conventional design?

The main problem for this, and the similar Caminez engine, is that the large reciprocating mass verses the relatively low rotating mass of the crank and prop causes a torsional vibration that is/was difficult to control in a light aircraft.
