This reciprocator has a frame comprising two spaced tracks 10, 12 and rigid members 14 and 16 spanning between the tracks. Fixed to the frame is a motor driving an output shaft to which a connecting rod 42 is eccentrically connected. The connecting rod can be secured to the axle of a perambulator to move it back and forth on the tracks when the motor is operational. The spacing of the tracks is adjustable to suit different perambulators. <IMAGE> |
