Table is moved from a near-vertical position to a horizontal position by a screw-type jack driven by an electric motor swingably mounted on a base member by a plate which also carries the jack assembly. The table includes an adjustable spreadable head rest and a foot rest. The foot rest supports the patient when the table is in its near-vertical position and may be swung to a depending position when the table is in its horizontal position. Interlock switches automatically stop the table in its near-vertical and horizontal positions. Another interlock switch takes the motor out of play when the foot rest is in its depending position with the table in its horizontal position so that the foot rest must be moved to a patient-supporting position before the table can be moved from its horizontal position to its near-vertical position.
