A safe and arm device is responsive to electrical signals by way of two solenoids that push and pull, respectively, an arm to rotate, in turn, each of a series of three cogwheels by steps. When each of the cogwheels has been rotated a given number of steps prescribed by a secret code, slots or cutou
A safe and arm device is responsive to electrical signals by way of two solenoids that push and pull, respectively, an arm to rotate, in turn, each of a series of three cogwheels by steps. When each of the cogwheels has been rotated a given number of steps prescribed by a secret code, slots or cutouts in each of the cogwheels are aligned to permit passage therethrough of an elongated bar or rack that can then operate or enable a switch or other mechanism to fire a rocket motor, etc.

Safety and arming mechanism responsive to electrical signals comprising, a first solenoid, a second solenoid, each of said first and second solenoids having an individually associated armature, an actuator arm having a first end and a second end, a rocker arm pivoted at an intermediate position ther
Safety and arming mechanism responsive to electrical signals comprising, a first solenoid, a second solenoid, each of said first and second solenoids having an individually associated armature, an actuator arm having a first end and a second end, a rocker arm pivoted at an intermediate position thereof and having a first end and a second end, the armature of said first solenoid being connected to the first end of said rocker arm and the armature of said second solenoid being connected to the second end of said rocker arm and to said first end of said actuator arm, track means for guiding said actuator arm, a series of coaxial cogwheels each of which has a cutout therein, wherein said track means includes an individual straight track section in alignment with each of said cogwheels and a curved section between each of said straight sections, an elongated bar, said first solenoid and said second solenoid being disposed in operative relation with said rocker arm and said actuator arm such that said first solenoid and said second solenoid give a pull stroke and a push stroke, respectively, to the first end of said actuator arm when an electrical signal is applied thereto, further including means for biasing said actuator arm to follow each curved section to the adjacent straight section each time said actuator arm is given a pull stroke, said actuator arm being disposed in operative relation with said track means and said cogwheels such that each pull stroke thereon moves the second end of said actuator arm sequentially from one cogwheel to the adjacent cogwheel in the series of cogwheels and each push stroke thereon rotates by a step the cogwheel with which the actuator arm is then in operative relation, said cogwheels being so arranged that each requires a different number of rotative steps to bring its cutout into alignment with the cutouts in the other cogwheels, whereby when each of the cogwheels has been rotated a predetermined number of steps prescribed by a secret code the cutouts in the series of cogwheels are aligned to permit passage therethrough of said elongated bar that can then allow arming.
