  • Patent number: 3980864
    Abstract: A switch is added to each spindle of a conventional mechanical voting machine where the spindle is rotated or otherwise actuated by a voter when casting a vote for a particular office. The switch is normally open and is closed by the movement of the spindle from a "no vote" position to a "vote" position. An electronic scanning device is connected to the switch of each spindle of the voting machine and electronically scans the condition of each switch of the voting machine when the vote is registered by the operation of the curtain handle by the voter. The electronically scanned output of each of the switches is then transmitted over telephone lines either instantaneously or after a given storage period which could last till the close of the polls, to centrally located computers at county, state, federal and news media locations. These computers keep a current running total of the vote in various categories and further provide print-out at the close of the polls.
