Definitions

  • This invention relates to electro-magnetic relays and is particularly designed for use in telephone and signalling systems or in other situations where it may be required to actuate any one contact or element or any one set of contacts or other elements of a group comprising a number of such elements or sets of elements.
  • any particular element or set of elements is effected by providing a relay for each of such elements or sets of elements and it is the object of the present invention to devise means whereby the required conditions may be obtained without the use of a number of independent relays with independent circuits and actuating means therefor, thus resulting in the cheapening of the cost and a simplification of manufactureand a decrease in maintenance charges.
  • the invention consists in a multiple electro-magnetic relay comprising a plurality of relay armatures actuated electro -magnetically and means whereby any particular armature may be operated or selected for operation without afiecting any of the other relay armatures.
  • the invention also consists in other details and arrangements hereinafter described or indicated.
  • Figure 1 is a perspective view.
  • Figure 2 is a transverse sectional elevation.
  • EigureB is a diagram of connections
  • FIG. 4 is a diagrammatic representation of the relay.
  • my improved multiple relay with the magnetic circuit composed of a yoke piece a secured to a core or bobbin comprising the units 6, c (for example, by being bolted thereto by means of end flanges on the yoke or by other suitable means) of a length determined by the number of relay armatures required to be embodied in the multiple relay.
  • the core or bobbin is formed along its length or is provided thereon with a number of flanges or rings d, the number of which is equal to the number of contacts or elements or setsof such elements requiringto be operated.
  • the flanges or rings is wound in the samemanner with an insulated wire coil 6 so that 1n this way I form a number of electroe magnetic coils with the leading-out Wire of one coil connected to the leading-in wire of the next and so on throughout the length of the bobbin, while the leading-out .wire of the last coil is connected to the leadingin wire of the first coil, the various joints between the coils being available in any suitable manner for external connection by means of contacts m.
  • the arrangement of the coils is clearly seen in the diagram in Flgure 3.
  • the end bobbins e are arranged at right angles to the bobbin 6 in order to reduce the length of the relay; Pivoted to or otherwise suspended from the yoke a are armatures f which maybe of the usual relay pattern and which are arranged so that each armature is opposite to its respective flange or ring d upon the bobbin with the usual air gap between, and the contacts 9 to be actuated by the relay are so arranged that any particular armature will actuate its appropriate set of contacts, leaving the others unaffected.
  • each pair of contacts m, n to be operated may be efiected in any known manner either manually by means of keys or automatically by means of a selective switch.
  • each pair of contacts m it may for instance be supposed to be operated by a key or push-button.
  • the relay may thus be operated at a distance over the circuits shown in Fig. 3, to
  • I may provide means whereby each armature may actuate more than one set of contacts.
  • I may provide means whereby each armature may actuate more than one set of contacts.
  • tha-t1 may modify the number and mode of ar rangement of the armatures, the means whereby such armatures may be adapted to actuate the contacts or other elements which they are to control and the form and arrangement of magnetic circuit adopted to suit the particular purpose for which the electro-magnetic relay is to be employed or any particular practical requirements tha may have to be fulfilled.
  • a multiple electro-magnetic relay comprising a single magnetic circuit, a plurality of electro-magnetically actuated relay armatures associated therewith, a number of magnetizingwindings and means for changing the path of the magnetic flux for selectively operating any one of the armat-ures, without affecting the other armatures.
  • a multiple electro-magnetic relay comprising a single magneticcircuit, a plurality of electro-magnet-ically operated armatures associated therewith, magnetically interconnected pole pieces arranged one opposite to each armature, a number of magnetizing windings and means for directing the magnetic flux through any oneof said pole pieces, for operating the correspondingarrings on the bobbin of such coils, a plurality of armatures registering with said rings,
  • a multiple electro-magnetic relay comprising a single magnetic circuit, a vplurality of electro-magnetically actuated relay armatures therefor, means whereby any particular armature may be operated without affectingany of the other armatures, a plurality of contacts in association with each armature, a distance piece between each armature and its contacts and means for moving said distance piece pivotally about the en abutting on to the armature so that each armature may actuate one or other of the contacts as required.
  • a multiple electro-magnetic relay comprising a plurality of coils separated by rings on the bobbin of such coils, a plurality of armatures registering with sald rings,
  • a battery may be connected between the joint of the end wires of the coils and joint between the wires of any two adjacent coils, a plurality of contacts associated with each armature, and means whereby each armature may actuate one or other of its plurality of contacts, substantially as described.
