Abstract
A dust director portable vacuum guard for mounting onto a bore of a portable angle grinder. The dust director includes a housing with parallel inner and outer walls and an end web adjacent to a straight barrel that is secured along aligned edges of the walls. The barrel is slotted from a forward dust collected end to the web and is stepped at a selected distance apart from the inner wall upper edge, functioning as a baffle. An attachment ring is pivotally mounted in the housing inner wall to releasably couple to an angle grinder bore and pivot around that bore upon release of a spring loaded thumb screw. An extension cover is included on an end of the housing to allow for sawing through a corner.

A dust director portable vacuum guard comprising, a housing formed from a stiff material to include a hollow straight tube as a barrel, a pair of thin flat inner and outer walls that are spaced apart, are essentially parallel to one another, and connect at right angles to a back wall, and each said inner and outer wall is connected along a straight edge to said straight tube, with said inner wall connection to said straight tube spaced a distance apart from an edge of a longitudinal slot formed in said straight tube that extends from a forward end of said straight tube to said back wall, providing an air baffle to a vacuum flow that is pulled through said barrel;
- an attachment ring for releasable mounting in an opening formed through said inner wall, adjacent to a corner of forward and bottom edges thereof, that is for receiving and mounting to a bore of an angle grinder fitted therein, and a leading edge of the inner and outer walls where said outer wall leading edge is straight and is set back from said inner wall leading edge, crossing an opening in an edge of said the inner wall, with said forward end of said straight tube approximately aligning with the leading edge of said inner wall;
- at least one thumb screw for releasably maintaining said attachment ring to turn in said inner wall opening;
- and at least one set screw fitted to turn through said attachment ring to mount said angle grinder bore to said attachment ring.
