for instance by the evening then the command is given to the delivery device to issue a command key by which the bathhouse supervisor can effect a recoding by means of this command key all permanent magnets as well as the recoding magnet 28 are brought out of engagement with the locking plate 12 the recoding magnet 28 therefore enters into the longitudinal groove 34 upon the subsequent displacement in the direction indicated by the arrow y by means of the command key 36 the corresponding end of the recoding pin 28 comes against the obstacle 33 in the longitudinal groove 34 and thereby brings about the turning of the carrier 24 and of the other carriers meshing with it in the direction shown by the arrow after a displacement of the pusher 6 the position shown in fig6 and 7 is reached the previous recoding magnet 28 has left its position of alignment with the longitudinal groove 34 while the recoding magnet 29 of the carrier 25 has come into the recoding position it is therefore no longer possible to effect a displacement of the pusher by means of the previous guest key because of the recoding magnets which are then shifted furthermore the guest must be issued a new guest key by means of which he can suitably displace all magnets.
