Sound-actuated animal-training device

Claim 1

An animal-training device adapted to be worn, and held in contact with the animal to be trained: comprising a pair of animal-shocking electrodes supportable by a suitable animal harness means; a power source including a capacitor; an oscillator circuit electrically interconnected between said power source and said electrodes for applying to said electrodes a burst of electrical pulses for each discharge of said capacitor; said oscillator circuit being connected across said capacitor and including a step-up transformer, a switching means for controlling the flow of current through the primary coil of said transformer, and an electrical feedback connection between a secondary coil of said transformer and said switching means so that said capacitor when charged may be discharged through said oscillator circuit to thereby generate said burst of pulses at the secondary coil of said transformer and thus at said electrodes; and trigger means for applying a control signal to said switching means so as to initiate the operation of said oscillator circuit and the discharge of said capacitor, said burst of pulses once started by said control signal being automatically continued by operation of said oscillator circuit and independent of the operation of said trigger means during the discharge of said capacitor.
