Claims20
A vacuum manifold for sawdust capture comprising:
- a vacuum manifold body portion, said body portion having a curved cylindrical internal surface region defining a cavity about a longitudinal axis thereof, said body portion having a first external surface region at a first end thereof, said first external surface region being disposed generally transverse to said longitudinal axis, said body portion including a second generally planar internal surface region, said second generally planar internal surface region being disposed substantially normal to said longitudinal axis, and wherein said curved internal surface region defines a correspondingly curved internal edge region with said second generally planar internal surface region.
A vacuum manifold for sawdust capture comprising:
- a vacuum manifold body portion, said body portion having a curved cylindrical internal surface region defining a cavity about a longitudinal axis thereof, said body portion having a first external surface region at a first end thereof, said first external surface region being disposed generally transverse to said longitudinal axis, said body portion including a second generally planar internal surface region, said second generally planar internal surface region being disposed substantially normal to said longitudinal axis, wherein said curved internal surface region defines a correspondingly curved internal edge region with said second generally planar internal surface region, said body portion including a third external surface region, said third external surface region being disposed normal to said first external surface region at a mutual edge thereof, said third external surface region having first, second and third internal edges, said first, second and third internal edges defining a generally rectangular aperture from said third external surface region into said cavity.
A vacuum manifold for sawdust capture comprising:
- a vacuum manifold body portion, said body portion having a first generally cylindrical internal surface region defining a generally cylindrical cavity therein, said generally cylindrical cavity opening, at a first end, to an aperture in a second external surface of said body portion, said generally cylindrical cavity terminated at a second end by a third substantially planar internal surface region, said third substantially planar internal surface region being disposed substantially normal to a longitudinal axis of said generally cylindrical cavity, said body portion having a fourth generally planar external surface region disposed in substantially parallel spaced relation to said longitudinal axis, said third substantially planar internal surface region forming a substantially linear mutual edge with said fourth generally planar external surface region.
