Abstract
A triggering mechanism suitable for sequential firing of ammunition from a firearm, wherein the firearm has multiple barrels, preferably two barrels, and the triggering mechanism allows the firing of ammunition sequentially from one barrel, then the second barrel.
Claims20
A sequential firing mechanism, comprising:
- a hammer, wherein said hammer extends from a pivot point to a distal end, said hammer comprising a hollow core, a front face, a first side and a second side, wherein said front face comprises at least one hole extending between said front face and said hollow core, wherein said first side comprises a first slot, wherein said second side comprises a second slot, and wherein said hammer has a seated position and a cocked position;
- a sequencing drum slidingly fitted in said hollow core of said hammer, wherein said sequencing drum comprises a bore and a follower pin slidingly fitted within said bore and extending beyond said bore and between said first slot and said second slot, wherein said sequencing drum has a first position and a second position and wherein said follower pin has a first side position with a first end extending beyond said first slot and a second side position with a second end extending beyond said second slot;
- a first guide rail proximate to said first slot, wherein said first guide rail engages said first end of said pin when said sequencing drum is in said first position and forces said sequencing drum to said second position as said hammer is moved between its seated position and its cocked position;
- and
- a second guide rail proximate to said second slot, wherein said second guide rail engages said second end of said pin when said sequencing drum is in said second position and forces said sequencing drum to said first position as said hammer is moved between its seated position and its cocked position.

A sequential firing mechanism, comprising:
- a breech plate, wherein said breech plate comprises at least a pair of firing pins;
- a hammer, wherein said hammer extends from a pivot point to a distal end, said hammer comprising a hollow core, at least one slot on a side of said hammer, and a front face with an exterior side and at least one hole extending from said exterior side to said hollow core, wherein said hammer has a seated position wherein said front face is adjacent to said breech plate and a cocked position rotated away from said breech plate;
- a sequencing drum slidably fitted in said hollow core of said hammer, wherein said sequencing drum comprises at least one pin with an end extending through said slot;
- and
- at least one guide rail proximate to said slot in said hammer, wherein said guide rails engages said end of said pin and slides said sequencing drum in said hollow core from a first position to a second position.
2 more elements
A sequential firing mechanism, comprising:
- a breech plate, wherein said breech plate comprises at least a pair of firing pins;
- a hammer, wherein said hammer extends longitudinally from a pivot point to a distal end, said hammer comprising a longitudinally-extending hollow core and a front face with an exterior side and at least one hole extending from said exterior side to said hollow core, wherein said hammer has a seated position wherein said front face is adjacent to said breech plate and a cocked position rotated away from said breech plate;
- an insert fitted in said hollow core of said hammer, wherein said insert has a protrusion extending out of said hollow core and moves from a first position to a second position within said hollow core;
- and
- an means for engaging said protrusion as said hammer rotates between said seated position and said cocked position, wherein said engaging means forces said insert between said first position and said second position.
