Abstract

A system has a drive mechanism affixed to an auger to selectively impart rotational forces to the auger for movement of pellet fuel for a cooking grill, and a lever arm affixed in a pivoting relationship to the drive mechanism and to a fixed location separate from the drive mechanism such that manipulation of the lever arm results in longitudinal movement of the auger.

First claim

What is claimed is:

1. A system comprising:
a drive mechanism affixed to an auger to selectively impart rotational forces to the auger for movement of pellet fuel for a cooking grill; and
a lever arm affixed in a pivoting relationship to the drive mechanism and to a fixed location separate from the drive mechanism such that manipulation of the lever arm results in longitudinal movement of the auger;
wherein:
the lever arm further comprises a lower transverse segment extending to a handle and a middle segment extending upward to an upper segment;
the upper segment is rotationally connected to the drive mechanism on an upper portion thereof; and
the upper segment is rotationally connected to a bracket on an air plenum as the fixed location separate from the drive mechanism.

2. The system of claim 1 , further comprising a handle affixed to the lever arm above a level of the auger.

3. The system of claim 1 , wherein the lever arm further comprises an upper transverse segment affixed to a handle on a first end and to a substantially upright segment on a second end, the substantially upright segment affixed to the drive mechanism on an upper portion thereof and affixed to the fixed location on a lower portion thereof.

4. The system of claim 3 , further comprising a bracket interposing the drive mechanism and the substantially upright segment and having a pivot axle fitted into an oblong opening in the substantially upright segment.

5. The system of claim 4 , further comprising a bracket affixed to an air intake plenum as the fixed location separate from the drive mechanism and connected to the lower portion of the substantially upright segment.

6. The system of claim 5 , further comprising a boss extending from the lower portion of the substantially upright segment to limit rotation of the lever arm with respect to the bracket affixed to the air intake plenum by contacting the air intake plenum.

7. The system of claim 1 , further comprising a handle affixed to the lever arm below a level of the auger.

8. The system of claim 1 , further comprising a bracket interposing the drive mechanism and the upper portion of the upper segment and connecting to the upper segment by an axle fitted into an oblong opening in the upper segment.

9. The system of claim 8 , further comprising a boss extending from the middle segment to limit rotation of the lever arm with respect to the fixed location by contacting the air plenum.

10. The system of claim 1 , further comprising an auger tube in which the auger rotates and through which the pellet fuel travels, the auger tube having a fixed relationship with respect to the fixed location separate from the drive mechanism such that longitudinal movement of the auger results in longitudinal movement of the auger within the auger tube.

11. The system of claim 10 , wherein the fixed location separate from the drive mechanism comprises an air plenum through which the auger tube and auger travel to a fire pot provided combustion air from the plenum.

12. A system comprising:
a drive mechanism affixed to an auger to selectively impart rotational forces to the auger for movement of pellet fuel for a cooking grill;
a lever arm affixed in a pivoting relationship to the drive mechanism and to a fixed location separate from the drive mechanism such that manipulation of the lever arm results in longitudinal movement of the auger; and
an auger tube in which the auger rotates and through which the pellet fuel travels, the auger tube having a fixed relationship with respect to the fixed location separate from the drive mechanism such that longitudinal movement of the auger results in longitudinal movement of the auger within the auger tube;
wherein the fixed location separate from the drive mechanism comprises an air plenum through which the auger tube and auger travel to a fire pot provided combustion air from the plenum.
