  • Torsion spring coupled drive mechanism for reciprocating device having hazard warning means
    Patent number: 4433529
    Abstract: An Agricultural combine having a sickle reciprocated by a wobble drive mechanism and a torsion bar coupled to the sickle to reduce the input torque requirement of the drive mechanism, is provided with a warning system to operate an alarm when energy is still stored in the torsion bar, unknown to the operator, when the drive mechanism is shut down and which stored energy could reciprocate the sickle and represent a hazard to the operator. The hazard warning system is disabled when the drive mechanism is operating.
