Abstract: A vacuum filter backflushing system having an air recapturing adapter coupled to a vacuum motor's air exhaust port which recaptures a portion of exhaust air and introduces the air into a recaptured air passage. The recaptured air passage is coupled to an air flow director which is configured to direct air to an air filter. The air flow director is configured to selectively prevent air from flowing through the filters in a normal air flow direction and allow the air in the recaptured air passage to backflush the filter by dislodging particles from air filter media. The recaptured air passage can terminate after a last air filter, such that the recaptured air passage is pressurized, or the recaptured air passage can recouple back into the air exhaust port or the air recapturing adapter, such that the air is in constant motion in the recaptured air passage.

Abstract: A system and method for capturing resultant dust from power tool operation are disclosed. The system comprises a device that includes a housing with a substantially cylindrical shape. The housing has a first end that tapers to an opening for a tool bit and at least one suction port that opens into an interior volume of the housing. The housing has a second end configured to couple to a power tool. An air intake passage attaches to the exterior surface of the housing body such that an interior volume of the air intake passage connects to an interior volume of the housing. An exit passage is coupled to the air intake passage and is configured to couple to a vacuum.

Abstract: A power tool accessory for elevating the base of a power tool from off a work surface and a method of use. The accessory or ski comprises a bridge, a first side wall coupled to the bridge, and a second side wall coupled to the bridge opposite the first side wall. The bridge, the first side wall, and the second side wall form an upper surface and an opening through which a power cord may pass. The upper surface is configured to receive a base of a power tool. Because the ski elevated the power tool from off of a work surface, dust, debris, and grit is not brought into the intake of the power tool, the power cord is not kinked, and the base of the power tool is not worn down on the work surface.

Abstract: A device for dissipating heat from a rotary power tool is disclosed. The rotary power tool comprises a hollow disc housing. On the top planar surface of the hollow disc housing, a plurality of hollow bolts traverse the surface of the hollow disc housing into the interior of the hollow disc housing. In the interior of the hollow disc housing, the hollow bolts create a substantially angled plane relative to the top planar surface of the hollow disc housing. The hollow disc housing encloses a heatsink. When the heatsink spins, it creates a vacuum, thereby drawing exterior air through the hollow bolts. The angled plane created by the hollow bolts directs the flow of air through the heatsink. The combination of the heatsink and the directed air flow serves to cool the rotary power tool and prevent overheating.

Abstract: A system and method are provided for capturing dust created from a work surface by a rotary tool attachment. A shield is comprised of a ridged shroud and a skirt. The shroud is configured to be coupled to a rotary tool, and to either fully enclose or partially expose the rotary tool attachment. The shroud has a plurality of air inlets, a first opening, and a second opening through the top surface of the shroud. The first opening receives a mechanical driveshaft of the rotary tool and the second opening is coupled to an external vacuum source. The skirt is coupled to a perimeter of the shroud and extends downward from above the top surface of the shroud and is configured to contact the work surface.
