Definitions

  • My invention relateslin nml a electra magneticrelays .and-has or its object theprovisionof a relay having a, variable time constant; and more especially, a relay having avariable time constant which is adjustable between ⁇ much wider limits than are the well known types of slow acting relays now in common VThe preferred means' used to. attain this and other useful objects will bedescribed fully hereinaten'reference being had to the accompan 'ng drawing. l
  • FIG. 1 shows a relay of my improved type connected for use in o eratingl a meter a predetermined time -af lr itsLcircuit is closed;
  • Figure 2 shows Vanother modification of the relay which is used in combination with a differential relay to hold a circuit openfor a certain definite time interval.
  • the outside-contact spring has a rod 6 which isattahed to it b any suitable means, as for example, by so ering, which carries an adjustable weight 7.
  • the contact springs arevclosed the weight 7 begins to' vibrate rapidly, and rapidl interrupts the.
  • circuitL of ⁇ 'the meter MV W ich was closed when theco'nta'ct lspriuggfs 4- and 5 irst came into engagement with each other.
  • the vmagnet-of the-meter is of high impedance and 'consequently does not fully energize so as-to attract itsarmature until-theweight 7 has stopped vibrat' -I have found by ex riment that'with t is arrangement I can clay the o ration of the meter as much as five secon s, and the riod of dela adjustable by re4 ating the stro e of the relay armatureand also to some extent b y moving the weight 7 up and down on the rod 6.
  • the contact device 3 may bemounted-upon the starting relay-of the master switch which relaywis necessarly energized whenever the master switchis operating.
  • the operation of the starting relay when-'the master switch moves the line switch plungers from one trunk to the next'in its ordinary operation of preselecting idle trunks does not close the circuit of relay 2 lon enough to permit the meter to register; an the longer closure of the circuit'of relay 2 ⁇ Y causedby the locking up ofthe,I master switch starting relay whilel the master switch operating 'spring is being retensioned by the solonoid is still not long J'enough to cause the meter Ato'register.
  • Fig. 2 1 have shown a modification of the invention which will be easil understood.
  • the purpose of the embo ent of cutea'p'rolon'ged opening of the circuit extendm over conductor 20 whenever the relay ⁇ 10 1s energized.
  • the operati-on is asfollowsz' When the circuit of relay 10-is closed at contact devices 21 it attracts its armature and closes contact springs '12and 13.
  • differential relay 11 will retract its armature and again close contact springs 18 and 19.'- Regulation of the 'time lnterval of the dierential relay is accomplished by adjusting the wei ht 17 on rod 16, and by regulating the ength of stroke of the armature of relay 10.
  • a relay having contact springs, means for l,closing said sprin when the relay is energized, and a'weig t attached to one of said -springs to cause the same to vibrate and. dela the permanent closure of said sprin s IW ile said relay is energized.
  • relay havin circuit controlling contact springs a weig t attached to one of said sprin to cause'the same ⁇ to vibrateand dela t e permanent closure of said springs w ile said relay is energized.
  • yA relay having contactv members ,-for closing a circuit when the rela is energized, a weight attached to one o said contact members to cause the same to vibrate when therelay is energized, said member vibrating with constantly diminishing amplitude
  • a relay.v having circuit controlling springs, said relay when energized causing its armature to be permanently attracted, and additional means on said relay for o'pening ⁇ said circuit controlling springs and for premeans on Asaid arm for delaying the permitn ent closure Vof ,said circuit controlling springs for a predetermined interval after the armature is attracted.
  • a relay having a pair of normali o en contact sprmgs, an armature for sai re ay effective when the same is energized to close said springs, and means on one of said springs for delaying the permanent closure of said springs for a predetermined eriod after the continued energization o said relay.
