The plug is screwed into the vent 4a by a rotary attachment 21 driven by an air motor 22 movable vertically by a cylinder 23. Air from a source 28 is supplied alternatively through pressure-reducing valve 24 and solenoid valve 26 for low torque and pressure-reducing valve 25 and solenoid valve 27 for high torque. The sequence of operations are controlled automatically by timing and limit switches. Operation.-When cylinder 2 has advanced to its limit to grip the battery 4 a switch is operated and cylinder 20 advances the jaws 16 which open by engagement of the pins 17 withthe cam levers 11, 11<SP>1</SP> and close on to end-most plug 8 on the shoot 6. At the limit of advance of the cylinder 20 another switch operates so that cylinders 12 advances a cam 13 to close levers 11, 11<SP>1</SP> and open jaws 9, 9<SP>1</SP>. At the end of the stroke of cylinder 12 the cylinder 20 retracts to an intermediate position where it is stopped by operation of a further switch. Thus, the plug 8 is withdrawn from the jaws 9, 9<SP>1</SP> and held by the jaws 16 above the vent 4a. Cylinder 23 and the valve 26 are operated so that the attachment 21 is lowered and rotated and the plug 8 is screwed with a low torque into the vent 4a. After a predetermined time, valve 26 closes and the cylinder 20 retracts to the final position of its stroke where it operates a further switch which opens high-torque valve 27 to complete the screwing operation on the plug. After a further predetermined time, the cylinder 2 retracts to release the battery and the cylinder 23 rises to lift the attachment 21. At the limit of retraction of the cylinder 2 a limit switch operates so that the conveyer 5 moves the battery away from the apparatus.
