Deboning machine

1. A deboning machine comprising:

a housing, said housing having a passageway and ports for expelling meat and bone from said housing;

a separation chamber mounted in said passageway of said housing, said separation chamber having an end;

an auger extending through said separation chamber and said housing, said auger rotatably attached to said housing; and

an engagement structure comprising a pin extending from one of said housing and said separation chamber and a pocket provided in the other of said housing and said separation chamber, said pocket having a camming surface, said pin being seated within said pocket to engage said separation chamber with said housing, wherein engagement of said pin with said camming surface provides a space between said separation chamber and said auger.

2. The deboning machine of claim 1 , wherein said pin extends from said housing, said pocket is provided in said separation chamber.

3. The deboning machine of claim 2 , wherein two said pins and pockets are provided.

4. The deboning machine of claim 2 , wherein said separation chamber has a first end which is first inserted into said passageway of said housing to engage said pin within said pocket, and a second opposite end, wherein said pocket is provided proximate to said second end of said separation chamber.

5. The deboning machine of claim 4 , wherein said separation chamber further includes a slot at said first end thereof, and said housing has a second pin extending therefrom, said second pin engaging with said slot when said separation chamber is seated within said housing.

6. The deboning machine of claim 2 , wherein said separation chamber has a first end which is first inserted into said passageway of said housing to engage said pin within said pocket, and a second opposite end, wherein said pocket is provided proximate to said first end of said separation chamber.

7. The deboning machine of claim 1 , wherein two said pins and pockets are provided.

8. The deboning machine of claim 7 , wherein two said pins are diametrically opposed on said housing.

9. The deboning machine of claim 1 , wherein said separation chamber has a first end which is first inserted into said passageway of said housing to engage said pin within said pocket, and a second opposite end, wherein said engagement structure on said separation chamber is provided proximate to said second end of said separation chamber.

10. The deboning machine of claim 1 , wherein said separation chamber has a first end which is first inserted into said passageway of said housing to engage said pin within said pocket, and a second opposite end, wherein said engagement structure on said separation chamber is provided proximate to said first end of said separation chamber.

11. The deboning machine of claim 1 , further comprising a ring valve mounted on said auger and a ratchet assembly attaching said ring valve to said housing.

12. The deboning machine of claim 1 , wherein said pocket has an entry section which is parallel to a centerline of the separation chamber, and said camming surface is angled relative to a line transverse to said centerline.

13. The deboning machine of claim 1 , wherein said separation chamber has a conical shape and at least one flat surface proximate to an end thereof, said flat being engaged by a wrench to rotate said separation chamber relative to said auger.

14. The deboning machine of claim 1 , further including a wrench capable of engaging with said separation chamber.

15. A method of assembling a deboning machine comprising:

inserting a separation chamber into a passageway of a housing, wherein during said insertion, an engagement structure provided on said housing and said separation chamber engages with each other;

inserting an auger into said separation chamber and said housing;

engaging said auger with said housing; and

holding said auger stationary and rotating said separation chamber relative to said auger and relative to said housing to provide a space between the separation chamber and the auger.

16. The method of claim 15 , further comprising using a wrench to engage a flat surface on said separation chamber to rotate said separation chamber relative to said auger and relative to said housing.

17. The method of claim 15 , wherein said engagement structure comprises a pin provided on one of said housing and said separation chamber and a pocket provided in the other of said housing and said separation chamber, said pocket having a camming surface, wherein during insertion of said separation chamber into said housing, said pin seats within said pocket and engages with a camming surface of said pocket.
