Abstract
A liquified gas dry-cleaning machine having a cleaning vessel with a chamber for containing a wash bath and items to be cleaned and a removable door for sealing the cleaning chamber during a dry-cleaning operation. The dry-cleaning machine has a door opening and closing apparatus which includes a pivot frame for moving the door outwardly from the cleaning vessel in an arced path of movement, and a slide for lowering the door on the pivot frame in a linear path of movement to a position below the level of the cleaning vessel. Reverse movement of the pivot frame thereupon positions the door in a tucked stored position at the same axial location with respect to the cleaning vessel as when the door is closed so as not to impede access to the cleaning chamber nor increase the axial reach of an operator necessary for removing items from the chamber. The door opening and closing apparatus further includes a protective plate which is carried by the pivot frame and is movable between a raised position for protecting operating personnel during door opening and closing operations and a lower position for permitting access to the cleaning chamber following a door opening operation.
