Definitions

  • the present invention relates to change-over devices and more particularly to such devices which comprises an oscillatory armature relay.
  • the invention consists in the novel parts, constructions, arrangements, combinations, and improvements herein shown and described.
  • Fig. l is a front elevation of a change-over relay or electric switch embodying my invention and showing a circuit in which it is arranged.
  • Fig. 2 is a top plan view, partly in section, of the relay.
  • a change over mechanism comprising an oscillatory armature which is energized at intervals is provided with an auxiliary detent armature controlled by the same field as the oscillatory armature.
  • This auxiliary armature acts on the oscillatory armature in such a manner that after energisation of the relay, by means of a first impulse, it holds the oscillatory armature in the attracted position and after energisation of the relay by means of a second impulse again releases the oscillatory armature and allows it to return to its position of rest.
  • Thetravel and inertia of the oscillatory armature can be such that on energisation of the relay by a short impulse it is moved out of its position of rest through the place of maximum flux density, in which operation on the subsequent falling back of the auxiliary detent armature it is locked and on energisation of the relay by the second impulse it is again released and thus after cessation of the impulse it can no longer be held by the auxiliary detent armature and can return to its position of rest.
  • the oscillatory armature relay is formed so that the oscillatory armature actuates a change-over contactor, which itself from time to time again interrupts the relay current circuit closed from a place of actuation. In order to synchronise the relays which may have fallen out of step, the strength of the first impulse can be made greater than that of the secondimpulse.
  • the oscillatory armature relay consists of an upright magnet coil 3 and field piece 4, the latter having the pole pieces I, 2 projecting outward through a non-magnetic inner supporting plate 4'; and an oscillatory armature 5, an auxiliary detent armature 6 and a change-over switch I mounted on said inner supporting plate and an outer non-magnetic supporting plate 4a secured to the plate 4'.
  • the oscillatory armature 5, which is subject to the torque of a returning spring 3 bears a change-over pin in acting on the central contact 9 of the change-over switch I, and an abutment pin II to engage the end of the auxiliary detent armature B.
  • the two outer contacts l2, l3 of the change-over switch I are in electrical connection with the contacts [4, [5 of a change-over switch I i also having an oscillatory contact It.
  • the switching apparatus is connected to a source of current l8.
  • the movements of the oscillatory armature are employed to effect any desired switching-over motion.
  • the counting mechanism can be changed over from one to theother counting mechanism and this change over maintained by'theauxiliary detent armature.
  • the pivotal shaft 2! of the oscillatory armature can be connected to a lever, which acts in a known manner on the change-over pinion of the doubleori meter mechanism.
  • This arrangement is not shown in the drawing, as it is well known in the art and forms no part of the present invention.
  • an electrical one can obviously be employed
  • the oscillatory armature relay is also directly applicable for purposes other than for changing the tariii.
  • the change-over device on the relay is obviously dispensed with. If a whole series of oscillatory armature relays is actuated by the changeover switch, it is advantageous that one osci1latory armature relay with a change-over device shall co-act with the change-over switch, whilst the remaining relays are connected in parallel with this relay and have no change-over devices.
  • a resistance 22 is advantageously inserted in the branch conductor between the contacts is and I5, whereby the result is obtained that the first impulse is stronger than, the second. In the first stronger impulse,
  • the oscillatory armature is attracted and in the second weaker impulse it is released by the auxiliary detent armature.
  • This second weaker impulse is sufficient to lift the auxiliary detent armature and thus release the main armature, but not to bring the oscillatory armature from the position of rest into the locked position, so that synchronisation of the relay is obtained in a simple manner, and thereby any falling out of step of the relay is avoided in practice.
  • a change-over relay comprising in combination an oscillatory armature to be oscillated by an electrically energized magnetic field from a position of rest to an oscillated position to and through the position of magnetic equilibrium and an auxiliary detent armature normally arranged in detaining position and embodying a unitary element controlled by the magnet field through successive intermittent impulses energizing and deenergizing said field so as-to be first attracted by a first impulse produced field and moved to non-detaining position, then released and allowed to move to detaining position to engage and hold the oscillatory armature in its oscillated position on the interruption of said produced field, and then attracted to non-detaining position by a second impulse produced field to release the armature and finally allowed to move back to its normal detaining position on the interruption of such second field.
  • a changemver relay comprising in combination an oscillatory armature having opposed poles and mounted for oscillation centrally on a horizontal transverse axis in a magnetic field between coacting poles, and energized by intermittent electric impulses to oscillate said armature from its postiion of rest to an oscillated position into and through the position of magnetic equilibrium, and an auxiliary detent armature normally arranged in detaining position and embodying a unitary element controlled by the magnet field through successive intermittent impulses energizing and deenergizing said field so as' to be first attracted by a first impulse produced field and moved to non-detaining position, then released and allowed to move to detaining position to engage and hold the oscillatory armature in its oscillated position on the interruption of said produced field, and then attracted to non-detaining position by a second impulse produced field to release the armature and finally allowed to move back to its normal detaining position on the interruption of such second field.
  • a change-over relay comprising in combination an oscillatory armature having spaced poles and mounted for oscillation centrally on a horizontal transverse axis between coacting poles in a magnetic field energized by intermittent current impulses from a position of rest to an oscillated position into and through the place of maximum flux intensity, a pair of switches to energize said magnetic field when closed actuated by the armature on its opposite movements to close one of said switches when the armature is in the position of rest and the other of said switches when the armature is in the oscillated position, said switches being opened by slight movements of said armature away from said positions, and an auxiliary detent armature controlled by the magnetic field for movements into and out of detaining position and adapted to be moved successively out of detaining position and their back into detaining position to engage and hold the armature in oscillated position after alternate energizations of the magnetic field,
