Claims20
A vacuum manifold for sawdust capture comprising:
- a flange portion and a body portion, said flange portion including a generally planar surface region oriented in a first orientation, said body portion having a generally circularly cylindrical internal surface region defining a cavity about a longitudinal axis thereof, said longitudinal axis being generally perpendicular to said generally planar surface region, said circularly cylindrical internal surface region bordered, in part, by a slot having a curved edge region, said slot defining a slot plane, said slot plane being disposed substantially perpendicular to said longitudinal axis, said slot being sized and configured to receive a portion of a saw blade therethrough, an upper terminal edge of said circularly cylindrical internal surface region being disposed in common with a further substantially planar internal surface region, said substantially planar internal surface region forming an acute plane angle with an external surface region of said body at a further edge thereof;
- and
- an aperture through said flange portion for withdrawing said sawdust.
A vacuum manifold for sawdust capture comprising:
- a flange portion and a body portion, said flange portion including a generally planar surface region oriented in a first orientation and an aperture through said flange portion for withdrawing said sawdust, said body portion having a generally circularly cylindrical internal surface region defining a cavity about a longitudinal axis thereof, said longitudinal axis being generally perpendicular to said generally planar surface region, said circularly cylindrical internal surface region bordered, in part, by a slot, said slot defining a slot plane, said slot plane being disposed substantially perpendicular to said longitudinal axis, said slot being sized and configured to receive a portion of a saw blade therethrough wherein said circularly cylindrical internal surface region is arranged and configured to promote the formation of vortices therewithin when in operation.
A vacuum manifold for sawdust capture comprising:
- a flange portion and a body portion, said flange portion including a generally planar surface region oriented in a first orientation, said body portion disposed inwardly of said flange portion and including a further substantially planar surface region disposed in substantially parallel spaced relation to said planar surface region, said body portion having a generally circularly cylindrical internal surface region defining a cavity about a longitudinal axis thereof, said longitudinal axis being generally perpendicular to said generally planar surface region, said circularly cylindrical internal surface region terminated, in part, by an arcuate edge, said arcuate edge defining a slot, said slot defining a slot plane, said slot plane being disposed substantially perpendicular to said longitudinal axis, said slot being sized and configured to receive a portion of a saw blade there through;
- and
- a hose coupling tube disposed outwardly of said flange portion.
A vacuum manifold for sawdust capture comprising:
- a flange portion and a body portion, said flange portion including a generally planar surface region oriented in a first orientation and an aperture through said flange portion for withdrawing said sawdust, said body portion having a generally circularly cylindrical internal surface region defining a cavity about a longitudinal axis thereof, said longitudinal axis being generally perpendicular to said generally planar surface region, said circularly cylindrical internal surface region bordered, in part, by a slot, said slot defining a slot plane, said slot plane being disposed substantially perpendicular to said longitudinal axis, said slot being sized and configured to receive a portion of a saw blade therethrough;
- a supporting apparatus, said supporting apparatus coupled to said flange portion, said supporting apparatus being adapted to maintain a lower external surface region of said body portion at a substantially finite manifold clearance above a corresponding surface region of an underlying substrate.
A vacuum manifold for sawdust capture comprising:
- a flange portion and a body portion, said flange portion including a generally planar surface region oriented in a first orientation, said body portion having a generally circularly cylindrical internal surface region defining a cavity about a longitudinal axis thereof, said longitudinal axis being generally perpendicular to said generally planar surface region, said circularly cylindrical internal surface region bordered, in part, by a curved edge region, said curved edge region defining a slot, said slot defining a slot plane, said slot plane being disposed substantially perpendicular to said longitudinal axis, said slot being sized and configured to receive a portion of a saw blade therethrough, a lower terminal edge of said circularly cylindrical internal surface region being disposed in common with a further substantially planar internal surface region, said substantially planar internal surface region forming an acute plane angle with an external surface region of said body at a further edge thereof;
- and
- an aperture through said flange portion for withdrawing said sawdust.
