  • firing equipment for simulating gunfire comprises a plurality of firing cups for accommodating, pyrotechnic devices securely mounted on a support member, each firing cup being associated with a separate detonating device which can be set off, as selected, by means of control apparatus, in which the support member is connected to a holder having portions which, in use, abut against a gun-barrel, which holder is adjustable such that it may be mounted on gun-barrels of different diameters.
  • firing equipment for simulating gunfire including a plurality of firing cups for accommodating pyrotechnic devices, each firing cup being associated with a separate detonating device which can be set off by means of control apparatus which includes a stepping switch actuable by the release contact ofa gun to route successive detonating impulses to different firing cups.
  • the invention allows an arrangement wherein each time the release contact of the gun is actuated, one of the detonating devices is set off, and at the same time the next shot is prepared by means of the stepping
  • the stepping switch can be constructed to operate cyclically, and can comprise a moving contact engageable with any one of a plurality of output contacts, each connected to one of the detonating devices.
  • the stepping switch can include at least one additional output contact connected to a warning means for indicating that the equipment is ready for operation.
  • a convenient form of cyclically operable stepping switch can be obtained by making the moving contact rotatable, the output contacts being arranged in at least part of a circle centered on the axis of rotation of the moving contact.
  • a manually operable impulse emitting means can be provided for actuating the stepping switch so that the stepping switch can be switched to a position in which the system is ready for operation.
  • Connectors 100 and 102 are connected to the release contact (not i
  • the energizing coil 108 can also be switched to the positive lead 112 by means of a handoperated impulse-emitting means 110, contact 1060 being normally closed.
  • the stepping switch comprises a moving contact 114 which is actuated by the energizing coil 108, i. e., is rotated in the direction of the arrow, and which in the ready position as illustrated applies voltage to a warning lamp 116 through the output contact 118.
  • the moving contact 114 is rotated one step as each impulse is sent, until it reaches the ready position again.
  • the moving contact 114 successively connects the output contacts 120, 121 30 to the positive lead, but detonation of pyrotechnic devices does not occur since the working contact l06b interrupts the negative lead to the detonating devices, the other supply lead of which is connected to one of the outputs each time.
  • the lead to the impulse-emitting means 110 is first interrupted, since the normally closed contact 106a is opened. Continuation of the switching operation can therefore now only take place bymeans of the impulses passed through the connectors 100 and 102 from the release contact of the gun, the connection of which to the energizing coil 108 is achieved by closing of the working contact 10611. Furthermore, the working contact 106d connects the negative lead 104 to the detonating devices, which are not illustrated, and the working contact 106a closes the current circuit of a warning light l34for indicating that the equipment is prepared for firing.
  • the moving contact of the stepping switch moves one step along to contact the output contact 120.
  • the pyrotechnic device associated with the detonating device connected to the output contact 12 is thus detonated.
  • a control lamp 120' lights up, and the ready signal given by the warning lamp 116 is extinguished.
  • one pyrotechnic device is fired after another in a sequence determined by the outputs 121 130, until the moving contact 114 has completed one revolution.
  • the control lamps 121' 130 associated with the other outputs light up in a corresponding sequence.
  • lamps 120' 130 are fitted in a line on the front side of the control apparatus, so that the control lamps to the left of the control lamp that has just lit up indicate which pyrotechnic devices have been fired, and those control lamps to the right indicate the pyrotechnic devices still in hand.
  • Other arrangements are of course possible and, in certain cases, preferable.
  • Apparatus for controlling the sequential firing of a number of pyrotechnic devices for simulating gunfire in response to trigger signals generated by operation of the gun trigger comprising:
  • a stepping switch including a number of output contacts individually providing a firing signal for a respective one of said pyrotechnic devices, a center terminal connected to one terminal of said DC. voltage source, a rotating contact member for sequentially interconnecting said center terminal with a respective one of said number of output contacts, and coil means for rotating said contact member;
  • key means interconnecting said connector and said voltage source with said coil for actuating said apparatus, said key means having an operative and an inoperative position and including first, second, third and fourth switch contacts, said first, second and third switch contacts are open and said fourth switch contact is closed with said key means in said inoperative position, said first, second and third switch contacts are closed and said fourth switch contact is open with said key means in said operative position;
  • said fourth switch contact connection said one terminal of said DC. voltage source to said coil means with said key means inoperative;
  • a first indicator for indicating said operative and inoperative positions of said key means
  • said first switch contact connects said first indicator to said DC. voltage source terminals, said second switch contact connects said additional output terminal to the other terminal of said DC. voltage number of indicators each individually connected to a respective one of said output contacts for indicating said firing signal for a respective one of said pyrotechnic devices.
  • stepping switch includes an additional output contact and further comprising an additional indicator connected between said additional output contact and the other terminal of said voltage source for indicating a starting position of said stepping switch.
  • stepping switch includes an additional output contact and further comprising an additional indicator connected between said additional output contact and the other terminal of said voltage source for indicating a starting position of said stepping switch.
