Abstract: An adaptor base for a telephone instrument that facilitates the instrument's use in both desk and wall mounted modes. Simplified construction allows the telephone user to reposition the base from one position to another, and even back to the first position if desired. The adaptor base is also so designed that the base and associated telephone can be mounted on a standard jack for a wall mounted telephone.

Abstract: A mechanism for automatically restoring an operated and depressed pushbutton line key in a multi-line key telephone instrument. When the telephone instruments handset is returned to the instruments cradle, the cradle rotates a cradle shaft which in turn rotates a hookswitch and a restoral actuator mounted to the shaft. The hookswitch actuator operates hookswitch contact springs placing the instrument in the "on-hook" condition and simultaneously the restoral actuator moves a button restoral arm which swings horizontally about a pivot. Restoral linkage mounted to the restoral arm transfers the arms' motion to an interlock lever which also pivots applying a mechanical force on the line key latch bar, unlatching the depressed pushbutton and restoring it to its original or non-operated position.
