Definitions

  • the invention relates to electric percussion igniters or fuses for shells or the like which can operate with or without delay, and which receive their ignition energy .from a remote point.
  • the electric device of the igniter is so constructed that it is possible selectively to set for delayed ignition or ignition without delay by the special way of supplying the electrical ignition energy.
  • the charging device for the fuse becomes at the same time the means for setting it to the desired type of ignition.
  • Figs. 1 and 2 are diagrammatic views of two different forms of the variation of its energy supply relatively 'to the other condenser, f or f2, through a high resistance, 2 or i2.
  • the i 'tion material L of igniter A operates wlthout retardation, while that, h2, o igniter A2, operates with retardation.
  • a vcharging apparatus B To suppkly the energy and, at the same time, to make t e/desired adjustment of the ignition, there is a vcharging apparatus B, coma source of current with three termipri nalsslls2 and s3 for the igniter.
  • To the positive terminal of the source of current can be consecutively connected, by switch 8, for example, the charging contacts s', s2, while the contact 83 is connected to the negative pole.
  • the igniter has four surface contacts la', k2, les and c, insulated from'each other and connected to the corresponding (positive) poles of the condensers e f', e2 and f2, and which,V
  • densers come in contact with the negative pole 83 of the source of current through the metal of the shell, as shown.
  • the charging contact s2, or the charging contact s' is connected to the positive pole of the source of current by means of theswitch s, so that either igniter A or A2 receives the current.
  • switch s can also be so arranged that the delay igniter A2 will also receive current, as a precaution, when the no delay igniter A does.
  • thesource Vof current in charging apparatus B is arranged to supply two different potentials, for example, 150 and 200 volts, which can be selectively set u by means of, switch s, between the negative c arging contact as and the positive pole s.
  • Both circuits -A (without delay) and A2 (with delay) of the igniter A are maintained, by the charging connections of their condensers, so connected together that, after the insertion of the igniter in the charging apparatus, both are connected to the energized charging contacts s' and s".
  • an electric relay for example .
  • a spark gap Z 2 weefsel gaseous potential arrester
  • the lower potential of the source is supplied to the charging contacts s and s3, by the switch s.
  • the relay Z- prevents the current from entering the circuit A2 for no delay since the momentar-y chargingvoltage lies helow the voltage necessary to break down said relay. lt is only when the higher voltage of the source is imposed at the contacts s' and s?, that the no dela 7 circuit A. is also charged,and the latter, W en percussion takes place, causes an immediate ignition.
  • Percussion fuse comprising two ignition circuits, either of which can be connected to an outside source of energy, one of said circuits causing undelayed ignition and the other delayed ignition.
  • Percussion fuse comprising two ignition circuits, both of which can be connected to an outside source of energy, one of said c ircuits operating without retardation and containing a relay, whereby it is capable of being charged only by a voltage of a certain magnitude.
  • Percussion fuse comprising two ignition circuits, each containing a condenser and one containing a relay operable only by a voltage of predetermined magnitude, an outside source of current having two di'erent voltages, and means to connect said circuits to said sourcei l In testimony whereof I alix my signature.
