Monolithic extractor system for a shotgun

Abstract

A two piece ejection system for a shotgun includes a chamber portion having a first, second and third section of varying outside diameters and an extractor formed from a hollow cylindrical tube having a first and second end, the second end including a plurality of slots. The slots are configured to allow the extractor to slide over the circumference of the third section of the chamber portion and be in sliding engagement with the second section of the chamber portion. Interference means on the plurality of slots and the sections of the chamber portion restrict the travel of the extractor over the second section of the chamber portion.

1 . A two piece ejection system for a shotgun, the ejection system comprising: 
 a chamber portion having a first, second and third section of varying outside diameters;    an extractor formed from a hollow cylindrical tube having a first and second end, the second end including a plurality of slots;    the slots being configured to allow the extractor to slide over the circumference of the third section of the chamber portion and being in sliding engagement with the second section of the chamber portion;    wherein interference means on the plurality of slots and the sections of the chamber portion restrict the travel of the extractor over the second section of the chamber portion.    
   
   
       2 . The two piece ejection system of  claim 1 , wherein the first section has a diameter A, the second section has a diameter B and the third section has a diameter C.  
   
   
       3 . The two piece ejection system of  claim 2 , wherein diameter B is smaller than diameter A and diameter C is larger than diameter B but smaller than diameter A.  
   
   
       4 . The two piece ejection system of  claim 1 , wherein the interference means is comprised of an interior expanded portion on each of the plurality of slots and a ledge formed at the intersection of the second and third sections of the chamber portion.  
   
   
       5 . The two piece ejection system of  claim 1 , wherein the first end of the extractor includes a U-shaped cutout and a rim around the circumference of the first end.  
   
   
       6 . The two piece ejection system of  claim 1 , wherein the plurality of slots are at least four slots.  
   
   
       7 . The two piece ejection system of  claim 1 , wherein the length of the extractor is between 2 to 0.8 inches.  
   
   
       8 . An ejection system for a shotgun, the ejection system comprising: 
 a chamber portion having a plurality of sections with varying outside diameters;    an extractor formed from a hollow cylindrical tube having a first and second end, the second end including a plurality of slots configured to allow the extractor to slide over the circumference of at least one of the chamber sections of varying outside diameters;    wherein when assembled, the two piece ejection system provides for movement of the extractor from a closed position to a full throw position.    
   
   
       9 . The ejection system of  claim 8 , wherein the plurality of sections include a first section having a diameter A, a second section having a diameter B and a third section having a diameter C, wherein diameter B is smaller than diameter A and diameter C is larger than diameter B but smaller than diameter A.  
   
   
       10 . The ejection system of  claim 8 , wherein interference means on the plurality of slots and the sections of the chamber portion restrict the travel of the extractor over a selected section of the chamber portion.  
   
   
       11 . The ejector system of  claim 10 , wherein the interference means is comprised of an interior expanded portion on each of the plurality of slots and a ledge formed at intersections of the sections of the chamber portion.  
   
   
       12 . The ejection system of  claim 8 , wherein the first end of the extractor includes a U-shaped cutout and a rim around the circumference of the first end.
