Combination flashlight-pyrotechnic signalling device launcher

A device comprising:

• a first section comprising a receptacle for a flashlight bulb, a battery compartment suitable for holding one or more batteries for powering said flashlight bulb and a switch for controlling power from the batteries to the bulb;
• a second section releasably coupled to said first section comprising three releasably coupled segments:
• a cocking segment, a firing mechanism, and a pyrotechnic signalling device compartment;
• said cocking segment having a first end and a second end, enclosing between said ends a cocking chamber for carrying a firing spring;
• said cocking chamber having a lip for engaging a firing pin catch;
• said firing mechanism having first and second ends, said first end releasably coupled to said second end of said cocking segment and said second end being releasably coupled to said pyrotechnic signalling device compartment, enclosing between its two ends a firing pin chamber suitable for carrying a firing pin and, at essentially right angles to said firing pin chamber a trigger chamber suitable for carrying a trigger, a sear and a trigger spring;
• said firing pin comprising a rod with a stepped flat sear stop, said rod having first and second ends and terminating at a first end in a striker suitable for detonating a pyrotechnic signalling device upon impact and at a second end in a shoulder;
• said firing pin having attached at or near its second end a firing pin catch of sufficiently small diameter to fit within said cocking chamber, but of sufficiently large diameter that it cannot pass said lip;
• said firing pin further having a slot along its long axis;
• said firing pin being carried in said cocking chamber and said firing pin chamber;
• a firing spring bearing on the shoulder of said firing pin so as to propel said firing pin forward when released;
• said trigger chamber carrying a trigger spring, a sear under pressure from said trigger spring said sear being connected to a trigger, said trigger passing through said firing pin through said slot so as to disengage said sear from said firing pin when said trigger is depressed;
• said pyrotechnic signalling device compartment having a first end releasably coupled to said second end of said firing mechanism and a second end permitting the exit of a pyrotechnic signalling device, defining between said ends a chamber suitable for carrying a pyrotechnic signalling device.

A safety trigger mechanism comprising:

• a firing pin chamber suitable for carrying a firing pin and, at essentially right angles to said firing pin chamber a trigger chamber suitable for carrying a trigger, a sear and a trigger spring;
• said firing pin comprising a rod with a stepped flat sear stop;
• said firing pin further having a slot along its long axis;
• said firing pin being carried in said firing pin chamber;
• a firing spring bearing on said firing pin so as to propel said firing pin forward when released;
• said trigger chamber carrying a trigger spring, a sear under pressure from said trigger spring said sear being connected to a trigger, said trigger passing through said firing pin through said slot, so as to disengage said sear from said firing pin when said trigger is depressed;
• said trigger having a spring-loaded safety pin extending therefrom;
• said trigger being rotatable between a first or "safe" position and a second or "fire" position;
• said trigger chamber having two positions between which said spring-loaded safety pin may be rotated:
• a "safe" position wherein said spring-loaded safety pin engages a safety shelf, said safety shelf being of a depth insufficient to permit the trigger to be depressed far enough to release the sear;
• and a "fire" wherein said spring-loaded safety pin bypasses said safety shelf and enters a portion of the trigger chamber having a depth sufficient to permit the trigger to be depressed far enough to release the sear.
