Abstract
The present invention pertains generally to power masonry tools and related devices for cutting and grinding. More specifically, the present invention relates to power saws of the “cutoff” type and systems that further maximize containment of dust contaminant while cutting cinder block, concrete, brick, clay, stone, tile and the like. An apparatus such as a rotatable filter system comprises a cylindrical filter housed in a filter chamber. The cylindrical filter comprises a first filter end cap and a second filter end cap, and wherein the first filter end cap and the second filter end cap are respectively configured to secure opposite ends of the cylindrical filter. A filter cleaning knob is configured to rotate the cylindrical filter. A filter cleaning flap is secured to an interior wall of the filter chamber and is configured to sequentially make contact with a plurality of pleated segments of the cylindrical filter as the filter cleaning knob is rotated. A vacuum suction tube is connected to a vacuum device wherein an annular rim protrusion extends from the vacuum suction tube, and wherein the annular rim protrusion is configured to mate with the second filter end cap via a gasket.
Claims (9)
1. An apparatus comprising: a cylindrical filter housed in a filter chamber, wherein the cylindrical filter comprises a first filter end cap and a second filter end cap, and wherein the first filter end cap and the second filter end cap are respectively configured to secure opposite ends of the cylindrical filter; a filter cleaning knob configured to rotate the cylindrical filter; a filter cleaning flap secured to an interior wall of the filter chamber and configured to sequentially make contact with a plurality of pleated segments of the cylindrical filter as the filter cleaning knob is rotated; and a vacuum suction tube connected to a vacuum device wherein an annular rim protrusion extends from the vacuum suction tube, and wherein the annular rim protrusion is configured to mate with the second filter end cap via a gasket.
2. The apparatus of claim 1, further comprising: a connection bolt configured to connect the filter cleaning knob to the first filter end cap, wherein the connection bolt penetrates a hole in an access panel; and a panel bushing configured to provide translational and rotational support to the connection bolt.
3. The apparatus of claim 2, wherein the second filter end cap further comprises a bearing seat acting as an abutment to a bearing.
4. The apparatus of claim 1, further comprising a housing comprising an upper housing portion and a lower housing portion, wherein the upper housing portion is configured to house the cylindrical filter, and wherein the lower housing portion is configured to house a dust collection bin, the dust collection bin configured to receive dust removed from the plurality of pleated segments of the cylindrical filter by the filter cleaning flap as the filter cleaning knob is rotated.
5. The apparatus of claim 1, wherein the vacuum suction tube is configured to connect to a vacuum device on a first end and to the cylindrical filter on a second end to facilitate a coupling of the cylindrical filter and the vacuum device.
6. The apparatus of claim 1, wherein the gasket is configured to provide a seal between the vacuum suction tube and the cylindrical filter.
7. The apparatus of claim 6, wherein the gasket is an annular seal configured to provide a thermal break between the intake port and the cylindrical filter.
8. The apparatus of claim 6, wherein the gasket is an annular seal of foam-like material.
9. The apparatus of claim 8, wherein the foam-like material is silicone foam.
