Abstract

A machine for distributing blowing wool from a bag of compressed blowing wool includes a chute having an inlet end and an outlet end, the chute configured to receive the bag of compressed blowing wool. A shredder is mounted at the outlet end of the chute and configured to shred and pick apart the blowing wool. A discharge mechanism distributes the blowing wool into an airstream. The chute is configured such that the minimum length of the chute from the inlet end to the outlet end is the nominal length of a person's arm.

Claims (24)

1. A machine for distributing blowing wool from a bag of compressed blowing wool, the machine comprising:

a chute having an inlet end, an outlet end, a top extending from the inlet end to the outlet end and having a top curved segment and a bottom extending from the inlet end to the outlet end and having a bottom curved segment, the bottom curved segment having a deflection ridge, the deflection ridge having an arcuate cross-sectional shape and including a peak segment, the deflection ridge having a slope extending upwardly to the peak segment, the slope of the deflection ridge configured to guide the blowing wool in a direction that includes an upward vertical component toward the peak segment, the chute configured to receive the bag of compressed blowing wool;

a shredder mounted at the outlet end of the chute and configured to shred and pick apart the blowing wool; and

a discharge mechanism for distributing the blowing wool into an airstream;

wherein the combined minimum length from the inlet end of the chute to the peak segment and from the outlet end of the chute to the peak segment is the nominal length of a person's arm.

2. The machine of claim 1 in which the chute is a one piece segment.

3. The machine of claim 1 in which the chute is pivotally mounted to allow access to the outlet end of the chute and the shredder.

4. The machine of claim 1 in which the chute has illuminated internal viewing ports to allow the machine user to view the blowing wool passing through the chute.

5. The machine of claim 1 in which the chute is collapsible.

6. The machine of claim 5 in which the collapsible chute has a plurality of segments.

7. The machine of claim 6 in which the segments of the collapsible chute are nestable.

8. The machine of claim 6 in which the segments of the collapsible chute can be folded upon themselves.

9. The machine of claim 5 in which the collapsible chute has a bellows configuration.

10. The machine of claim 5 including a locking mechanism to fix the collapsible chute in an extended position.

11. The machine of claim 5 in which the chute is easily removable and replaceable by means of clamps, clips or bolts.

12. The machine of claim 5 in which the chute is comprised of a plurality of separable segments.

13. A machine for distributing blowing wool from a bag of compressed blowing wool, the machine comprising:

a chute having an inlet end, an outlet end, a top extending from the inlet end to the outlet end and having a top curved segment and a bottom extending from the inlet end to the outlet end and having a bottom curved segment, the bottom curved segment having a deflection ridge including a peak segment, the deflection ridge having a slope extending upwardly to the peak segment, slope of the deflection ridge configured to guide the blowing wool in a direction that includes an upward vertical component toward the peak segment, the chute configured to receive the bag of compressed blowing wool;

a shelf slidably attached to the inlet end of the chute and having a cutting mechanism to open the bag of blowing wool, the shelf being configured to slide from a retracted position to an extended position and guide the bag into the inlet end of the chute;

a shredder mounted at an outlet end of the chute and configured to shred and pick apart the blowing wool; and

a discharge mechanism for distributing the blowing wool and shredded bag into an airstream.

14. The machine of claim 13 in which the shelf can be moved relative to the inlet end of the chute.

15. The machine of claim 13 in which the shelf includes an electrical interlock.

16. The machine of claim 13 in which the shelf includes a ram member configured to contact and drive the bag of compressed blowing wool through the chute.
