Abstract

A machine for distributing blowing insulation material from a package of compressed loosefill insulation material is provided. The machine includes a chute having an inlet portion and outlet portion. The inlet portion is configured to receive the package of compressed loosefill insulation material. A lower unit is configured to receive the compressed loosefill insulation material exiting the outlet portion of the chute. The lower unit includes a plurality of shredders and a discharge mechanism. The discharge mechanism is configured to discharge conditioned loosefill insulation material into an airstream. The discharge mechanism includes a hose outlet plate assembly configured to cover an outlet end of the discharge mechanism and is further configured to connect a distribution hose to the discharge mechanism. The hose outlet plate assembly includes a tapered passage extending from the outlet end of the discharge mechanism to the distribution hose.

First claim

What is claimed is:

1. A system for distributing blowing insulation material from a package of compressed loosefill insulation material, the machine comprising:
a chute having an inlet portion and outlet portion, the inlet portion configured to receive the package of compressed loosefill insulation material; and
a lower unit configured to receive the compressed loosefill insulation material exiting the outlet portion of the chute, the lower unit including a plurality of shredders and a discharge mechanism, the discharge mechanism configured to discharge conditioned loosefill insulation material into an airstream, the discharge mechanism including a hose outlet plate assembly configured to cover an outlet end of the discharge mechanism and further configured to connect a distribution hose to the discharge mechanism, the hose outlet plate assembly including an inner passage defined by a tapered transitional wall of a first segment and an inner wall of a second segment, the tapered transitional wall of the first segment having an inner perimeter and an outer perimeter, the outer perimeter having a diameter that is less than an inner diameter of the second segment.

2. The system of claim 1 , wherein the tapered passage is defined by a transitional wall forming an angle in a range of from 30° to 60°.

3. The system of claim 2 , wherein the angle is formed between the transitional wall and a surface of an inner portion of an outlet plate.

4. The system of claim 1 , wherein the tapered passage connects with a portion of a support having a circular cross-sectional shape.

5. The system of claim 1 , wherein the tapered passage narrows in a downstream direction.

6. The system of claim 1 , wherein the tapered passage is defined at one end by a transitional wall having a non-circular perimeter.

7. The system of claim 6 , wherein the non-circular perimeter has the cross-sectional shape of an egg.

8. The system of claim 7 , wherein the non-circular perimeter has an arcuate first end configured to abut an eccentric segment of a discharge mechanism housing.

9. The system of claim 8 , wherein the non-circular perimeter has an arcuate second end that has a smaller radius than a radius of the arcuate first end.

10. The system of claim 1 , wherein the tapered passage is defined by a transitional wall, the transitional wall having an inner perimeter with a length that is longer than a length of an outer perimeter.

11. The system of claim 10 , wherein the inner perimeter has the cross-sectional shape of an egg.

12. The system of claim 11 , wherein the outer perimeter has a circular cross-sectional shape.

13. The system of claim 12 , wherein the transitional wall forms a taper from the inner perimeter to the outer perimeter.

14. The system of claim 10 , wherein the inner perimeter has an arcuate first end configured to abut an eccentric segment of a discharge mechanism housing.

15. The system of claim 14 , wherein the inner perimeter is configured to cover an eccentric region formed by the discharge mechanism housing.

16. The system of claim 1 , wherein the tapered passage is defined at one end by a transitional wall having a perimeter, wherein the perimeter occupies a wedge-shaped space between adjacent sealing vane assemblies.

17. The system of claim 16 , wherein the perimeter has an arcuate first end configured to abut an eccentric segment of a discharge mechanism housing.

18. The system of claim 17 , wherein the perimeter has an arcuate second end configured to abut a valve shaft.

19. The system of claim 18 , wherein the perimeter has opposing sides connecting the first and second ends, and wherein the opposing sides are configured to abut portions of adjacent sealing vane assemblies.

20. The system of claim 16 , wherein the wedge-shaped space between adjacent sealing vane assemblies includes an eccentric region.
