ABSTRACT:
A locking mechanism for use with two evaporators comprises first and second anesthetic evaporators each having a respective rotatable first and second side-by-side opening valve disc with a radially extending opening therein with an arm located between the disc which has a transverse bore therethrough. The cylindrical latch is slidable in the bore and has an accommodation recess adjacent each of its ends at aligned diametrical locations. A control pin is carried by each of the discs and enters into the opening at one diametrical location and is of a size to be accommodated within the accommodation recess of the latch when the pin and the opening are properly aligned with the accommodation recess of the latch. The latch is positionable in the opening of either selected disc with the pin accommodated within the accommodation recess in a position at which its opposite end frees the other disc for rotation for opening its associated evaporator. The latch is also positionable between the disc so that its respective ends into each opening of each disc to lock both of the discs to prevent opening of both evaporators.
