Abstract: An automatic cocking device is provided for a chiropractic table of the type having a pivotally mounted pelvic support section which is adapted to be cocked to an elevated position by rotation of a cocking shaft and adapted to be tripped to a dropped position by chiropractic thrusts. The cocking device has an electric motor which is connected through a speed reducing gear train and an eccentric mechanical linkage to a crank which is mounted on the cocking shaft of the table, so that the cocking shaft is rotated to cock the pelvic support section. The electric motor is controlled by a parallel-connected circuit having at least one foot-operated switch and a cam follower switch which is actuated by a cam driven by the output shaft of the speed reducer, so that the output shaft which drives the eccentric linkage makes substantially one full revolution upon actuation of the foot-operated switch.
