Abstract

A muzzle loading firearm has a barrel with a bore defining a bore axis. The barrel has a muzzle end and a breech end, with a breech plug removably attached to the barrel and having a rear surface. An extractor is connected to the barrel and has a portion positioned rearward of the plug, and movable away from a position rearward of the plug, so that the plug may be removed without removing the extractor. The extractor may pivot, and may have a cylindrical portion received in a bore parallel to the barrel bore. The rear face of the extractor may be flush with the rear face of the breech plug.

Claims (31)

1. A muzzle loading firearm comprising:

a barrel with a bore defining a bore axis, and having a muzzle end and a breech end;

a frame connected to the barrel, and having a breech face;

the frame being movable between an open position in which the breech face is away from the breech end of the barrel, and a closed position in which the breech face abuts the breech end of the barrel;

a breech plug removably attached to the barrel and having a rear surface defining a central primer receptacle;

an extractor connected to the barrel and having a primer-engaging portion adjacent to the primer receptacle;

the extractor being operable in response to movement of the frame to the open position to move the primer-engaging portion in a first direction away from the breech plug to extract a primer; and

the primer-engaging portion of the extractor being movable in a different second direction such that the breech plug may be removed without removal of the extractor.

2. The firearm of claim 1 wherein the extractor is pivotally connected to the barrel.

3. The firearm of claim 2 wherein the extractor pivots about an extractor axis parallel to the bore axis.

4. The firearm of claim 1 wherein the extractor is an L-shaped body with a first elongated portion defining a pivot axis, and a perpendicular second portion having a free end with a lip for engaging a primer.

5. The firearm of claim 1 wherein the barrel includes an attached block defining a second bore receiving a first potion of the extractor.

6. The firearm of claim 5 wherein at least a portion of the first portion has a cylindrical profile.

7. The firearm of claim 6 including a spring detent element protruding into the bore, and wherein the first portion of the extractor includes a non-cylindrical portion adjacent to the detent element, such that the detent element engages the non-cylindrical portion to retain the extractor in a selected orientation.

8. The firearm of claim 7 where the non-cylindrical portion is a flat surface.

9. The firearm of claim 1 wherein the breech plug defines a slot that closely receives a portion of the extractor, such that neither the breech plug nor the extractor may be rotated when the extractor portion is received in the slot.

10. The firearm of claim 9 wherein extractor portion has a rear face that is flush with the plug rear surface when the extractor portion fully occupies the slot.

11. A muzzle loading firearm comprising:

a barrel with a bore defining a bore axis, and having a muzzle end and a breech end;

a breech plug removably attached to the barrel and having a rear surface;

an extractor connected to the barrel and having an extractor portion rearward of the plug; and

the extractor portion being movable laterally with respect to the bore axis away from a position rearward of the plug, such that the plug may be removed without removing the extractor.

12. The firearm of claim 11 wherein the extractor is pivotally connected to the barrel.

13. The firearm of claim 12 wherein the extractor pivots about an extractor axis parallel to the bore axis.

14. The firearm of claim 11 wherein the extractor is an L-shaped body with a first elongated portion defining a pivot axis, and a perpendicular second portion having a free end with a lip for engaging a primer residing in a pocket defined in the rear surface of the plug.

15. The firearm of claim 11 wherein the barrel includes an attached block defining a second bore receiving a first potion of the extractor.

16. The firearm of claim 15 wherein at least a portion of the first portion has a cylindrical profile.

17. The firearm of claim 16 including a spring detent element protruding into the bore, and wherein the first portion of the extractor includes a non-cylindrical portion adjacent to the detent element, such that the detent element engages the non-cylindrical portion to retain the extractor in a selected orientation.

18. The firearm of claim 17 where the non-cylindrical portion is a flat surface.

19. The firearm of clam 11 wherein the breech plug defines a slot that closely receives a portion of the extractor, such that neither the breech plug nor the extractor may be rotated when the extractor portion is received in the slot.

20. The firearm of claim 19 wherein extractor portion has a rear face that is flush with the plug rear surface when the extractor portion fully occupies the slot.
