Abstract
Abstract A writing implement containing electrical circuitry for keeping and displaying time. The implement includes an elongated barrel portion with a writing element having a tip portion protruding from one end thereof and an electrical time keeping device defined by an elongated support in the form of a chip or circuit board disposed within the barrel portion and having a plurality of numerical display elements which extend in a row longitudinally of the barrel of the implement and are aligned behind an elongated window which extends across a longitudinally extending opening in the wall of the barrel. Structures are provided for easily retaining and removing a battery with respect to the barrel to arrange it in circuit with electrical circuitry supported by the circuit board. Structures are also provided for easily removing the elongated circuit board from the barrel and replacing it with another board or after it has been repaired.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
278 words
An electrically operated time indicating appliance comprising in combination with an assembly including an elongated tubular barrel defining a housing for said appliance, a first opening in the side wall of said barrel and a transparent window means extending across and sealing said first opening, a writing implement secured to said assembly and protruding from an end thereof, a second opening to said barrel providing longitudinal access to the interior of said barrel, closure means, and means for removably securing said closure means across said second opening, an elongated electrical circuit board having electrical circuit means operable for computing and generating time defining electrical signals and display means secured to a major surface of said circuit board and connected to said electrical circuit means for variably generating a visual indication of time in accordance with the signals generated by the electrical circuit means of said circuit board, said elongated electrical circuit board being narrower than said second opening to permit said circuit board to be endwise inserted into said second opening and to be moved longitudinally through said barrel, means for slidably supporting said elongated circuit board within said barrel aligned with said transparent window means to permit said display means to be viewed from the exterior of said housing through said first opening and to permit the removal of said circuit board through said second opening when said closure means is removed, and an electric battery and means for electrically connecting said battery to said electrical circuit means including means for receiving said battery and means for compressing said battery against said connecting means when said barrel, said receiving means and said circuit board are operatively assembled.
Claim 2
Dependent Claim
278 words
An electrically operated time indicating appliance comprising in combination with an assembly including an elongated tubular barrel defining a housing for said appliance, a first opening in the side wall of said barrel and a transparent window means extending across and sealing said first opening, a writing implement secured to said assembly and protruding from an end thereof, a second opening to said barrel providing longitudinal access to the interior of said barrel, closure means, and means for removably securing said closure means across said second opening, an elongated electrical circuit board having electrical circuit means operable for computing and generating time defining electrical signals and display means secured to a major surface of said circuit board and connected to said electrical circuit means for variably generating a visual indication of time in accordance with the signals generated by the electrical circuit means of said circuit board, said elongated electrical circuit board being narrower than said second opening to permit said circuit board to be endwise inserted into said second opening and to be moved longitudinally through said barrel, means for slidably supporting said elongated circuit board within said barrel aligned with said transparent window means to permit said display means to be viewed from the exterior of said housing through said first opening and to permit the removal of said circuit board through said second opening when said closure means is removed, and an electric battery and means for electrically connecting said battery to said electrical circuit means including means for receiving said battery and means for compressing said battery against said connecting means when said barrel, said receiving means and said circuit board are operatively assembled.
Claim 3
Dependent Claim
26 words
An appliance in accordance with claim 1 wherein said means for compressing said battery against said connecting means includes said closure means for said second opening.
Claim 4
Dependent Claim
35 words
An appliance in accordance with claim 2 wherein said closure means comprises a removable plug at one end of said tubular barrel, said removable plug supporting said elongated electrical circuit board within said tubular housing.
