Definitions

  • This invention relates to electrical relay systems particularly for use in the communication art in situations in which contacts belonging to the same circuit are to be connected in parallel or in series and wherein the closing of the circuit is dependent on events occurring in other circuits.
  • Object of the invention is an electric Contact device comprising at least one set of contacts iniluenced by at least two electromagnetic sys-y tems independent of each other.
  • Fig. l is a side view of a contact device with six electromagnetic systems, which, in
  • Fig. 2 are shown in a plan view.
  • Fig. 3 is a section along the line III- III in Fig. 2.
  • Fig. 4 is a section alongrthe line vIV--IV Fig. 2.
  • Fig. 5 is a side view seen in the direction of' the arrow V in Fig. 2.
  • Fig. 6 represents a schematic illustration of the 1 Ciaim. (o1. 20o-9s) 2 latterl is substantially parallel to the core 2 of the coil and has a head I3 carrying a stop I 4.
  • the amplitude of the armature rocking movementv can be adjusted by means of a screw I5.
  • the whole armature construction is arranged in such a way thatv the weight .of the armature presses the stop I4 againstV the lupper part of the magnet core 2. If necessary the effect of the armature weight can be ⁇ assistedy by .an initial tension in the springs or blades 6 of the s et of contacts.
  • the blades 6 are longer than the electromagnetic system 2, 4, I 2'.r In this way it is possible to render the contactmaking independent of the place of operation of the blades.
  • Each relay has a, core 2 slotted'at the bottom; the two halves 3 are bent along diierent directions in order to form a foot.
  • the cores 2 are fixed to the base plate I by means of screws 9.
  • Each relay has a coilrl overlying a carrier member 5 to which the blades 6 of a set of contacts are fixed, having tongues l projecting below the base plate I.
  • the soldered terminalsof the coil winding are designated by 8, Fig. 1.
  • a pair of pointed screws Il enter into notches of each core 2. They pass laterallyV through lugs on the lower part of an armature I2, and can be adjusted by lock nuts, to form a pivot support of the armature I2.
  • the platesthemselves may be arranged at different heights without modifying the coil construction,. merely by'xing them above or under the head I3 ⁇ of the. armature I 2.
  • the plates are designated by IBA- IGF in correspondence.withthe relays A, B, C,r D, E and F of Fig. 2 and, on attraction of the armature, are moved in a direction indicated by arrows.
  • the ⁇ setsv of.. contactsa belong. tothe relay A, the sets ofcontacts b to the-relayrB, etc.
  • the plate IBB On attraction of the armature of the relay B, the plate IBB closes the contacts a1, b1 and bz and opens the contact b3.
  • the plate IBB is without influence upon the contact az.
  • the plate IBC On attraction of the armature of the relay C, the plate IBC closes directly the contacts c1 and d1, opens by means of the loop 23 the contact c2 and, with a heel 24, engages the bar 2!! for opening the contact a2. At the same time the plate IGC, by means of the bar 28, moves the blade dz, in this way preparing closing of the Contact 112,161.
  • the plate IBD has a heel 25 extending within reach of a projection 26 of the plate IBC, so that on operation of the plate IBD all the contacts lying in the sphere of action of the plate IBC are operated. Besides this; by means of the bar 21, the contact da is opened and the contact d4 closed.
  • the plate 16E acts upon the blade of contact e1 and moves in the direction of the blades 0f the contacts d2. For closing the contacts d2, e1 the attraction of a pair of relays C and E or D and E is, therefore necessary. By means of the heel 29 the relay E- prevents ⁇ the armature of relay F from moving when E is excited. If this is not the case, attraction of the armature of relay F causes by means of the bar 30 the open ing ofthe contact f1 and they closing of the lcontact f2.
  • Fig. 7 illustrates by way of example a, simple connecting problem which can be solved with the relays H, J, K of Fig. 8 and a single contact.L
  • each separate armature prevents contact making which is only perfor ed when both armatures are attracted.
  • relay J is attracted the contact ly is reopened,l since the one initially tensioned blade of the. conl tact follows the movement of; plate lliJ.
  • relay H is attracted, this blade is; brought. back and the contact Z is again closed.
  • It K is opened both the excitation of relay H and that of relay J is without effect.
  • both armatures are caused to act independently of oney another upon the saine contact blade so that both armatures are able to communicate the same movement.
  • Them onV operation of a single armature the contact is closed.
  • the series connection of twov contacts can likewise be replacedby a, single contact if one causes each vof the two armatures ⁇ tov act upon one blade ofthe same contact in opposite directions so that the electric connection is onlyl perfectv when both armatures are attracted'.
  • An electrical relay system comprising, a plurality of relay magnets each having a movable armature, a set of resilient contact blades associated with each relay magnet, means carried by each relay armature engageable with the blades of the associated se-t to selectivelyA position its blade contacts into any one of a plurality of posi- ;tions, mechanical couplings between adjacent relay armatures whereby energizing of one relay magnet will inuence the contact positions in more than one blade set, and energizing circuits for said magnets, said mechanical couplings including means whereby-movement ofi one armature prevents movement of another armature.
