Abstract

An improved chip capturing device for a planer comprising a chip director hood attached to a wood planer housing and a tubular shaped chip transporter. A first aperture of generally oval shape is embodied within the chip transporter and positioned on a first end of the transporter while a second aperture of generally oval shape and of greater circumference than the first aperture is embodied and positioned on a second end of the transporter. A third aperture to facilitate the introduction of wood shavings and chips to the tubular shaped chip transporter is positioned generally between the first and second apertures, reflects a generally rectangular shape, and extends downwardly generally perpendicular to the chip capture hood.

Claims

1. An improved chip capturing device for a planer having a housing which includes a chip outlet, the improvement comprising:

a chip deflector hood attached to said housing and positioned adjacent to said chip outlet;

a tubular shaped chip transporter attached to said chip deflector hood;

a first aperture of generally oval shape within said chip transporter and positioned on a first end of said transporter;

a second aperture of generally oval shape within said chip transporter, said second aperture positioned generally opposite of said first aperture; and

a third aperture extending generally perpendicular to said chip deflector hood, said third aperture positioned generally between said first and second apertures.

2. An improved chip capturing device of claim 1 further comprising a chip flow baffle connected to said chip deflector hood and extending into said tubular shaped chip transporter.

3. The improved chip capturing device of claim 1 further comprising an airflow conduit attached to said chip deflector hood.

4. An improved chip capturing device as set forth in claim 1 wherein said housing includes an interior chamber, a motor driven blade member rotatably mounted to said housing and extending transversely of said interior chamber.

5. An improved chip capturing device as set forth in claim 4 wherein said chip outlet extends transversely of said interior chamber adjacent an upstream side of said blade member.

6. The improved chip capturing device of claim 1 wherein said chip deflector hood, said tubular shaped chip transporter, said chip flow baffle and said first, second and third apertures are a molded composition.

7. The improved chip capturing device of claim 1 further comprising:

a first tubular air transport vessel attached to said first aperture; and

a second tubular air transport vessel attached to said second aperture.

8. The improved chip capturing device of claim 7 wherein said first vessel is attached to an exhaust from a vacuum.

9. An improved chip capturing device for a planer having a housing which includes an interior chamber, a motor driven blade member rotatably mounted to said housing and extending transversely of said interior chamber, a chip outlet extending transversely of said interior chamber adjacent an upstream side of said blade member, and a table positioned below said blade member, the improvement comprising:

a chip deflector hood attached to said housing and positioned adjacent to said chip outlet;

a tubular shaped chip transporter attached to said chip deflector hood;

a first aperture of generally oval shape embodied within said chip transporter and positioned on a first end of said transporter;

a second aperture of generally oval shape embodied within said chip transporters, said second aperture of greater circumference than said first aperture and positioned generally opposite of said first aperture;

a third aperture of generally rectangular shape and extending generally perpendicular to said chip capture hoods, said third aperture positioned generally between said first and second apertures;

a chip flow baffle connected to said chip deflector hood and extending into said tubular shaped chip transporter;

a first tubular air transport vessel attached to said first aperture; and

a second tubular air transport vessel attached to said second aperture.

10. The improved chip capturing device of claim 9 wherein said chip deflector hood, said tubular shaped chip transporter, said chip flow baffle and said first, second and third apertures are embodied as a molded composition.

11. The improved chip capturing device of claim 9 further comprising an airflow conduit attached to said chip deflector hood.

12. An improved chip capturing device for a planer having a housing which includes an interior chamber, a motor driven blade member rotatably mounted to said housing and extending transversely of said interior chamber, a chip outlet extending transversely of said interior chamber adjacent an upstream side of said blade member, and a table positioned below said blade member, the improvement comprising:

a chip deflector hood attached to said housing and positioned adjacent to said chip outlet;

an airflow conduit attached to said chip deflector hood;

a tubular shaped chip transporter attached to said chip deflector hood;

a first aperture of generally oval shape embodied within said chip transporter and positioned on a first end of said transporter;

a second aperture of generally oval shape embodied within said chip transporters, said second aperture of greater circumference than said first aperture and positioned generally opposite of said first aperture;

a third aperture of generally rectangular shape and extending generally perpendicular to said chip capture hoods, said third aperture positioned generally between said first and second apertures;

a chip flow baffle connected to said chip deflector hood and extending into said tubular shaped chip transporter;

a first tubular air transport vessel attached to said first aperture; and

a second tubular air transport vessel attached to said second aperture.

13. The improved chip capturing device of claim 12 wherein said chip deflector, said airflow conduit, said tubular shaped chip transporter, said chip flow baffle, said airflow conduit and said first, second and third apertures are embodied as a molded composition.
