The invention relates to multi-sided eccentric ends for the head of an oscillating olive beating rod which ends possess a multi-sided core 1 from the centre of which passes through circular holes 9 the driving shaft 8. The core 1 is divided into twoequal sections 2 bearing equal number of incorporated rods 3 each. Inside the core 1 there is a polygonal base 4 of great area with shaped protuberances 5 and recesses 6 serving for the interconnection of sections 2. The protuberances 5 and the recesses 6 of the base 4 are inwardly extended and partially supported by semi-circular reinforcements 7. The multi-sided configuration of the core 1 and the great contact surface of the two sections 2 dispense the latter -throughout the operation of thedevice and the pressure applied on rods 3- with distortions. |
