  • Patent number: 5603505
    Abstract: A self-contained, power operated, portable target apparatus utilizing a base supported, linearally reciprocal carriage actuator driven by a reversible AC electric motor to actuate a crank along a vertical arc; the crank having pivotable connection with the carriage actuator at one end and positive fixed connection at its other end with a horizontal rotatably supported drive shaft for partially rotating the shaft in response to limited linear movements of the carriage actuator. Two, laterally spaced co-planar lift arms are secured to the shaft for movement between vertical and horizontal positions. Elongated target supporting pins project from near the outer free ends of the lift arms for inserted reception in connector sockets extending into the body of a three dimensional target. Heavy springs are coupled to the carriage actuator for assisting the motor in overcoming the inertia of the target load as it is raised from a horizontal or prone hidden position to an upright display position.
