Abstract
Abstract An accessory for a telephone to assist in the dialing of the digits of the telephone dial includes a housing that partially covers the telephone and has an opening therein through which the dial may be observed, an array of lights preferably disposed in a semi-circle about the dial with one light associated with each digit of the dial, and a stepping switch responsive to each dialing of the dial for stepping the stepping switch. The apparatus employs a code card having two sets of connectors that are interconnected in a predetermined pattern to identify an entire telephone number. This code card is coupled between the stepping switch and the light array and is adapted to control the successive illumination of the lights in a sequence corresponding to the telephone number and with one light being illuminated at a time associated with one digit which digit is the next one to be dialed.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
129 words
A telephone dialing aid comprising: a housing including means defining an opening for providing access to at least the dial of the telephone ; an array of indicator lights arranged so that one indicator light is associated with each position of the dial; sequencing means capable of selectively applying energy to one indicator light at a time and capable of assuming a plurality of positions; an actuator coupled to the sequencing means responsive to movement of the dial for advancing the sequencing means; and means intercoupling the sequencing means and the light array and arranged to couple the energy from the sequencing means to the indicator lights of the array in a sequence as the actuator advances the sequencing means corresponding to the digits of a predetermined telephone number.
Claim 2
Dependent Claim
129 words
