Definitions

  • My invention relates in general. to electromagnetic relays, and has for its object the provision of a new and improved slow acting relay which is slow to retract its armature when its energizing circuit is broken.
  • I provide a relay which may be energized by a short impulse of current and which will then retain its armature attracted for as much as live or ten seconds, depending on its adjustment, after the energizing impulse has ceased.
  • the latter spring is very flexible and has the rod 9 secured to it by soldering or other approved means.
  • the weight 10 carried on rod 9 is adjustable up and down. When the device is at rest contact springs 7 and 8 are separated, no matter whether armature 3 is attracted orretracted. These springs are adjusted rather close together, however.
  • the frequency of the vibrations can be adiusted by moving weight 10 u
  • the duration of series of vibrations, or the interval during which relay A will remain operated, can be adjusted by adjusting the stroke of armature 3 which controls the initial amplitude of the vibrations.
  • a slow acting relay means for energizing said relay, a locking circuit for said relay, and means set in motion by said relay when the same is energized and operating independent of said relay for transmitting a; series of impulses over said locking circuit.
  • a slow acting relay and a circuit therefor, means for transmitting a momentary current impulse over said circuit to energize said relay, a locking circuit for said relay, and a mechanical device operated by the initial energization of said relay for transmitting a pre-determined series of current impulses over said locking circuit.
  • a slow acting relay and a circuit therefor means fontransmitting a momentary current impulse over said circuit to energize said relay, a vibrating member set in motion when'said relay is energized and operating thereafter independent of magnetic attraction, and a locking circuit for said relay closed by said member while the same is vibrating.
  • a slow acting relay and a circuit therefor means for transmitting a momentary impulse of current over said circuit to energize said relay, a vibrating member set in motion when said relay is energized and operative during a predetermlned interval of time, a l0Cl1IlgQlTCl1ltfOr said relay, and means controlled by said vibrating member for transmitting impulses over said circuit.
  • a second circuit for said magnet means momentarily closing said first circuit to cause the attraction of said armature to initiate a. vibratory action of said member, said vibratory member thereafter vibrating with decreasing amplitude, and a contact operated by said member while vibrating for controlling said second circuit.
  • a slow acting relay an armature, a vibrating device set in motion by said armature when the same is attracted, a locking circuit for said relay, and a pair of contacts closed by said armature when the same is attracted and opened by said vibrating device at regular intervals thereafter to control said locking circuit.
  • a slow acting relay an operating circuit therefor, an armature, a vibrating device set in motion by said armature when the operating circuit is closed, a pair of contacts jointly controlled by said armature and vibrating device, and a second circuit for said relay independent of the first circuit controlled by said contacts.
