Abstract
Abstract The instrument described herein makes it possible for deaf persons to make telephone calls to, and to receive telephone calls from, other deaf persons and to enable speaking and nonspeaking deaf persons to make telephone calls to, and to receive telephone calls from hearing persons. The usual call signal or ring is transformed into a signal cognizable by the deaf, such as blinking light flashes. Voiced sounds are transformed into lights whereby the deaf person can receive information from speech. A telegraph key produces light signals for communication between the deaf.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
110 words
In apparatus for enabling deaf persons to use a telephone: one or more appliance serving sockets; control means operable to connect said service sockets to a source of electrical energy; means sensing the existence of a signal at the circuit of a telephone for operating said control means; means illuminable in accordance with the signal sensed by said sensing means to enable code communications; selectively operable means for disabling said control means while communications are in progress by the aid of said telephone circuit; and a plurality of auxiliary sensing means for said control means and operable independently of said disabling means for signalling events apart from said telephone circuit.
Claim 2
Dependent Claim
110 words
In apparatus for enabling deaf persons to use a telephone: one or more appliance serving sockets; control means operable to connect said service sockets to a source of electrical energy; means sensing the existence of a signal at the circuit of a telephone for operating said control means; means illuminable in accordance with the signal sensed by said sensing means to enable code communications; selectively operable means for disabling said control means while communications are in progress by the aid of said telephone circuit; and a plurality of auxiliary sensing means for said control means and operable independently of said disabling means for signalling events apart from said telephone circuit.
Claim 3
Dependent Claim
175 words
In apparatus for enabling deaf persons to use a telephone: a control unit; a first connector member and a second connector member carried by said control unit; means responsive to the existence of a signal at said first connector member for signalling a deaf person; means for connecting a source of electrical potential to said second connector member; a portable unit detachably connected to said control unit by the aid of third and fourth connector members respectively electrically engageable with said first and second connector members respectively; an amplifier and an illuminable lamp all carried by said portable unit; means connecting said illuminable lamp and said third connector member to the output of said amplifier; a telephone pickup member sensing the signal of a telephone circuit and connected to the input of said amplifier; connection means between said fourth connector member and said amplifier for providing a source of power therefor; and a battery carried by said portable unit for providing power to said connection means when said fourth and second connector members are disconnected.
Claim 4
Dependent Claim
175 words
In apparatus for enabling deaf persons to use a telephone: a control unit; a first connector member and a second connector member carried by said control unit; means responsive to the existence of a signal at said first connector member for signalling a deaf person; means for connecting a source of electrical potential to said second connector member; a portable unit detachably connected to said control unit by the aid of third and fourth connector members respectively electrically engageable with said first and second connector members respectively; an amplifier and an illuminable lamp all carried by said portable unit; means connecting said illuminable lamp and said third connector member to the output of said amplifier; a telephone pickup member sensing the signal of a telephone circuit and connected to the input of said amplifier; connection means between said fourth connector member and said amplifier for providing a source of power therefor; and a battery carried by said portable unit for providing power to said connection means when said fourth and second connector members are disconnected.
Claim 5
Dependent Claim
23 words
The apparatus as set forth in claim 2 together with a switch carried by said control unit for selectively disabling said signalling means.
Claim 6
Dependent Claim
32 words
The apparatus as set forth in claim 2 in which said battery is connected to said connection means by a switch closed only when said second and fourth connector members are disconnected.
Claim 7
Dependent Claim
45 words
The apparatus as set forth in claim 4 in which said pickup is detachably connected to said portable unit and in which said battery is connected to said connection means through a switch closed only when said pickup member is connected to said portable unit.
Claim 8
Dependent Claim
46 words
The combination as set forth in claim 2 together with an oscillator carried by said control unit; key means for controlling said oscillator; and means coupling the output of said oscillator to said telephone circuit including a speaker cooperable with the mouthpiece of a telephone instrument.
