ABSTRACT:
Device for propelling an inflated ball by elastic impact, includes an electromagnet 1, a plunger core 3 drawn by the coil, an oscillating lever 7, and a mechanical linkage 5, which connects the plunger core 3 to oscillating lever 7.
The oscillating lever 7 is connected to a striking lever 13 which pivots around an axle 14 fixed to the free end of oscillating lever 7. Striking lever 13 is made up of two arms of unequal length. At the end of the excursion of oscillating lever 7, the shorter arm 15 of striking lever 13 strikes against stop 32 which stops arm 15 and contributes to the acceleration of the longer arm 16 of striking lever 13; the striking mass 17 attached at the end of striking lever 13 thus strikes the inflated ball 22 at maximum speed.
