ABSTRACT:
A hand held spreading device is disclosed for broadcast spreading material via a rotating impeller. The device has an actuating assemly including an actuating member and a dual spring arrangement interconnected with the actuating member. One of the springs causes material to be discharged onto the impeller in response to movement of the actuating member and prevents damage of the device resulting from excessive movement of the actuating member. The second spring biases the actuating member to move to an idle position in which no material is discharged onto the impeller and causes the actuating member to return to this idle position after movement thereof.
