ABSTRACT:
A casing contains the operative portion of a telephone including a speaker adjacent one end and a microphone adjacent the other. The dialing mechanism includes a conventional rotary assembly actuated by a longitudinally extending slider bar mounted in the top surface of the casing. This slider bar includes a ratchet gear along one edge engaging with corresponding gear teeth formed or secured around the periphery of the rotary portion of said rotary assembly. Indicia are provided on the upper side of the slider bar and finger engaging means are also provided on the upper side of the slider bar with the indicia being between adjacent finger engaging means. The upper side of the slider bar is visible through an opening in the top of the casing and the slider bar is moved digitally along the opening until the finger of the operator engages one end of the opening whereupon the slider bar may be released and the spring of the rotary assembly returns the slider bar to the original position.
