Portable morse code signaling device

Claim 1

A hand-held signaling device for flashing light in Morse Code comprising, a light source, normally open circuit means for energizing said light source including a source of energy, a shift register having a plurality of flip-flops for intermittently closing said normally open circuit means and energizing said light source, an encoder having a plurality of switches arranged in first and second circuit paths and connected to selected flip-flops in said shift register, a first oscillator connected to said shift register for pulsing and clearing said flip-flops in said shift register, a second oscillator, and a selector gate connected between said second oscillator and Said encoder for alternately switching the output of said second oscillator to said first and second circuit paths whereby a first arrangement of flip-flop settings is made in said shift register when said first circuit path is connected between said encoder and said shift register thereby intermittently energizing said light source to flash in Morse Code a first alphabetical letter when said shift register is pulsed and cleared, and whereby a second arrangement of flipflop settings is made in said shift register when said second circuit path is connected between said encoder and said shift register thereby intermittently energizing said light source to flash in Morse Code a second alphabetical letter different from said first alphabetical letter when said shift register is pulsed and cleared.
