I have not worked out exactly what is going on in this patent.
In the 1930s Victor Simon had obtained a series of patents showing simple, but well executed, designs, and had gone on to actually manufacture a number of exactly as simple, and well executed, Rota derailleurs.
In contrast, this patent seems to show a device of bewildering complexity - and I have no evidence that it was ever manufactured.
However this patent does tell us the Victor Simon's interest in derailleurs continued after the Second World War - at least unitl 1950. After this date Victor continued to take out patents, but they were not related to derailleurs or even to cycling.
