Abstract of the Disclosure A transfer mechanism especially suited for use in the handling and transfer of non-ambulatory hospital patients and having at least one thin plate-like support movable from a retracted position relative to a deck outwardly over a bed or other surface to or from which the patient is to be transferred and loaded by extension of the support under the patient. The support plate is extensible beyond its own width and also through a distance larger than the width of a deck structure on which it may be superimposed by virtue of a carriage assembly with which the separator is translated. Friction between the patient and the laterally translated support is avoided by a thin flexible apron covering the support and movable relative to it in a manner such that the surface presented to the patient is either stationary or movable with the separator. An unique drive arrangement is provided by which translation of the support, carriage relative to the deck and of the apron relative to the separator may be effected by a single reversible drive motor for supplying torque to a translating drive chain mechanism which may be coupled or decoupled from a second apron driving endless chain depending on the drive parameters called for by the particular mode of mechanism operation. In addition to the aforementioned apron, a lower apron formed by a double ended belt may extend around a lower separator as well as the extensible portion of the carriage assembly so that movement of the second or lower separ- ator and the carriage relative to the bed or other surface may be isolated. The translating drive chain mechanism also operates a winding roller to pay in or out one end of the lower apron.
