    Abstract: A DRIVE COUPLING SYSTEM IN A XEROGRAPHIC MACHINE FOR SYNCHRONIZING THE RECIPROCATION OF A COPY CARRIAGE WITH A ROTATABLE XEROGRAPHIC DRUM. A CLUTCH RELEASABLY COUPLES A DRIVEN MEMBER TO A ROTATABLE DRIVE IN SYNCHRONISM WITH A SPECIFIC POINT ON THE ROTATABLE DRIVE TO PROVIDE LIMITED MOVEMENT OF THE DRIVEN MEMBER FROM A FIRST TO A SECOND POSITION IN ONE DIRECTION. AN ADDITIONAL DRIVE CONSISTING

    OF A SPRING MOTOR DRIVES THE DRIVEN MEMBER IN THE OPPOSITE DIRECTION TO THE FIRST POSITION. A CAM MEMBER CONTROLS THE ACCELERATION AND DECELERATION OF THE DRIVEN MEMBER FROM AND TO THE FIRST POSITION.

    Abstract: A failsafe system is provided for a copying machine which will operate in response to one of a plurality of sensing devices to stop the xerographic copying process, immediately deenergize the fuser assembly and energize an auxiliary drive system which will merely return the reciprocatable document carriage to the home position so that the original document may be retrieved. When the document carriage reaches the home position, the auxiliary drive system will be shut off with the cover latching mechanism deactivated to prevent the initiation of further cycles until such time as repairs are made and the system is reset for normal operation.
