Abstract

A burner retraction system includes a mounting assembly having a mounting sleeve, an insertion assembly having a tubular sleeve including an insertion portion sized and shaped for insertion into the mounting sleeve and an opening therethrough, a pivot rod rigidly mounted to and extending rearwardly from the mounting plate, and a pivot assembly rigidly mounted to the insertion sleeve and including a pivot tube surrounding and coaxially rotatable about the pivot rod, one of the pivot rod and the pivot tube having a slot including a straight axially extending portion and an angled portion extending rearwardly from the straight portion at an angle θ, and a stop pin slidably inserted into the slot in the one of the pivot rod and the pivot tube, the stop pin being secured to the other of the pivot rod and the pivot tube.

First claim

The invention claimed is:

1. A burner retraction system, comprising:
a mounting assembly having a mounting plate and a mounting sleeve extending rearwardly from the mounting plate, the mounting sleeve having an axis;
an insertion assembly having a tubular sleeve including an insertion portion sized and shaped for insertion into the mounting sleeve of the mounting assembly, the tubular sleeve including an opening therethrough;
a pivot rod rigidly mounted to and extending rearwardly from the mounting plate, the pivot rod having an axis, and a pivot assembly rigidly mounted to the insertion sleeve and including a pivot tube surrounding and coaxially rotatable about the pivot rod, one of the pivot rod and the pivot tube having a slot including a straight portion extending in the axial direction of the pivot tube, an angled portion extending rearwardly from the straight portion at an angle θ with respect to the axial direction of the pivot tube, and a stop end terminating the angled portion; and
a stop pin slidably inserted into the slot in the one of the pivot rod and the pivot tube, the stop pin being secured to the other of the pivot rod and the pivot tube, such that when the insertion assembly is moved rearwardly with respect to the mounting assembly, the insertion portion of the insertion assembly is first retracted straight back from the mounting assembly as the stop pin slides in the straight portion of the slot, and the insertion assembly is then guided to rotate about the pivot rod away from the axis of the mounting assembly as the stop pin slides in the angled portion of the slot, until the stop end of the slot comes into contact with the stop pin; wherein
the insertion assembly is a burner body and the tubular sleeve forms an outer wall of a burner.

2. The burner retraction system of claim 1 , wherein the pivot tube includes the slot and the stop pin is secured to the pivot rod.

3. The burner retraction system of claim 1 , wherein the pivot rod includes the slot and the stop pin is secured to the pivot tube.

4. The burner retraction system of any one of claims 1 to 3 , wherein the insertion assembly is configured to receive and support at least a portion of a burner mounted within the tubular sleeve.

5. The burner retraction system of any one of claims 1 to 3 , wherein the mounting assembly is a burner body and the mounting sleeve forms an outer wall of a burner, and wherein the insertion assembly is a portion of the burner and the tubular sleeve forms an inner conduit within the burner.

6. The burner retraction system of claim 1 ,
the mounting assembly further including a collar protruding radially outward from a rear end of the mounting sleeve; and
the insertion assembly further including an external portion of the support sleeve extending rearwardly from the insertion portion of the tubular sleeve and a collar protruding radially outward from the tubular sleeve at a junction between the insertion portion and the external portion;
wherein the mounting assembly collar and the insertion assembly collar are configured to be adjacent to one another when the insertion portion of the tubular sleeve is fully inserted into the mounting sleeve.

7. The burner retraction system of claim 1 , the pivot assembly further comprising a mounting bracket rigidly affixed to the pivot tube and removably mounted to the tubular sleeve.

8. The burner retraction system of any one of the preceding claim 1 , wherein the mounting sleeve includes an inner bevel and the insertion portion of the tubular sleeve includes an outer bevel to facilitate alignment of the tubular sleeve with the mounting sleeve during insertion of the insertion portion into the mounting sleeve.

9. The burner retraction system of claim 1 , further comprising an annular bushing positioned between the pivot rod and the pivot tube at each end of the pivot tube.

10. The burner retraction system of any one of the preceding claim 1 , further comprising an annular bushing surrounding the stop pin to facilitate sliding of the stop pin with the slot of the pivot tube.

11. The burner retraction system of claim 1 , wherein the angle θ is from about 8 degrees to about 55 degrees.

12. The burner retraction system of claim 11 , wherein the angle θ is from about 12 degrees to about 35 degrees.

13. The burner retraction system of claim 12 , wherein the angle θ is from about 18 degrees to about 25 degrees.

14. The burner retraction system of claim 1 , further comprising a burner mounted in the tubular sleeve.

15. A burner retraction system, comprising:
a mounting assembly having a mountain plate and a mounting sleeve extending rearwardly from the mounting plate, the mounting sleeve having an axis;
an insertion assembly having a tubular sleeve including an insertion portion sized and shaped for insertion into the mounting sleeve of the mounting assembly, the tubular sleeve including an opening therethrough;
a pivot rod rigidly mounted to and extending rearwardly from the mounting plate, the pivot rod having an axis;
a pivot assembly rigidly mounted to the tubular sleeve and including a pivot tube surrounding and coaxially rotatable about the pivot rod, the pivot tube having a slot including a straight portion extending in the axial direction of the pivot tube, an angled portion extending rearwardly from the straight portion at an angle θ with respect to the axial direction of the pivot tube, and a stop end terminating the angled portion; and
a stop pin slidably inserted through the slot in the pivot tube and secured to the pivot rod, such that when the insertion assembly is moved rearwardly with respect to the mounting assembly, the insertion portion of the insertion assembly is first retracted straight back from the mounting assembly as the stop pin slides in the straight portion of the slot, and the insertion assembly is than guided to rotate about the pivot rod away from the axis of the mountain assembly as the stop pin slides in the angled portion of the slot, until the stop end of the slot comes into contact with the stop pin; wherein
the insertion assembly is a burner body and the tubular sleeve forms an outer wall of a burner.

16. The burner retraction system of claim 15 , wherein the insertion assembly is configured to receive and support at least a portion of a burner mounted within the tubular sleeve.

17. The burner retraction system of claim 15 , wherein the mounting assembly is a burner body and the mounting sleeve forms an outer wall of a burner, and wherein the insertion assembly is a portion of the burner and the tubular sleeve forms an inner conduit within the burner.

18. A burner retraction system, comprising:
a mounting assembly having a mounting plate and a mounting sleeve extending rearwardly from the mounting plate, the mounting sleeve having an axis;
an insertion assembly having a tubular sleeve including an insertion portion sized and shaped for insertion into the mounting sleeve of the mounting assembly, the tubular sleeve including an opening therethrough;
a pivot rod rigidly mounted to and extending rearwardly from the mounting plate, the pivot rod having an axis and a slot including a straight portion extending in the axial direction of the pivot rod, an angled portion extending rearwardly from the straight portion at an angle θ with respect to the axial direction of the pivot rod, and a stop end terminating the angled portion;
a pivot assembly rigidly mounted to the tubular sleeve and including a pivot tube surrounding and coaxially rotatable about the pivot rod; and
a stop pin sec
