Claim 1
Independent Claim
86 words
A talking book including at least one page having thereon visual material and substantially V shaped sound grooves which have signal information recorded thereon concerning said visual material and which signal information is adapted for reproduction by relative movement between said page and a substantially pointed penlike, manually held, sound pick-up stylus transducer, characterized in that the page has at least one set of two or more adjacent and parallel sound grooves thereon in which all of the grooves of each set have identical recorded information.
Claim 2
Dependent Claim
86 words
A talking book including at least one page having thereon visual material and substantially V shaped sound grooves which have signal information recorded thereon concerning said visual material and which signal information is adapted for reproduction by relative movement between said page and a substantially pointed penlike, manually held, sound pick-up stylus transducer, characterized in that the page has at least one set of two or more adjacent and parallel sound grooves thereon in which all of the grooves of each set have identical recorded information.
Claim 3
Dependent Claim
109 words
A talking book in accordance with claim 1 wherein said manually held sound pick-up stylus transducer comprises a barrel and a moving element which is resiliently supported within said barrel by an elastic cylinder and into which a substantially sharp stylus is permanently affixed and made an integral part of said moving element whose exposed end supporting the said stylus is conical in shape, the moving element is characterized by said shape including an angle of less than 88* and truncated at its apex to form a protective skirt not less than one-sixteenth inch in diameter about the said sharp stylus which protrudes not more than one thirty-second inch.
