Abstract
The present invention is a dust collection assembly for capturing dust, debris and residue that is created during the process of drilling holes into a concrete ceiling. The dust collection assembly is used with a universal drill stand and a drill saddle which has an electric drill secured to it. The drill saddle further comprises a telescoping vacuum tube having a ceiling contact portion that encircles the drill bit at the portion of the drill bit where the drill bit enters the ceiling. As the drill bit begins to penetrate the ceiling, silica dust is generated and removed via the vacuum tube, which tube is connected to a vacuum source.
Claims9
A dust collection assembly for use with a universal drill stand, the stand for use with a drill and the stand comprising:
- a vertical wash-down pneumatic cylinder having an uppermost portion;
- a horizontal base for supporting the vertical cylinder;
- a pole clamp offset disposed at the uppermost portion of the vertical cylinder;
- an offset tube disposed within the pole clamp offset and having an uppermost portion;
- a drill saddle disposed at the uppermost portion of the offset tube;
- and
- means for actuating the cylinder to elevate the offset tube and drill saddle for drilling a hole into a concrete ceiling or other overhead surface;
- the dust collection assembly comprising:
- a substantially vertical outer collection tube, the outer collection tube configured for attachment to the drill saddle;
- an inner collection tube, a substantially vertical portion of the inner collection tube disposed within the outer collection tube and a substantially horizontal portion of the inner collection tube configured for parallel placement to a ceiling surface;
- a compression spring in the outer collection tube to urge the inner collection tube upwardly;
- a vacuum hose connected at a first end to the outer collection tube and at a second end to a vacuum;
- and
- a vacuum site tube and dual aperture structure forming an opening for a drill bit to pass through and forming a vacuum and air passage continuum through the inner collection tube, the outer collection tube, and the vacuum hose.
A universal drill stand and dust collection assembly for use with a drill having a drill bit, the stand and assembly comprising:
- a movable horizontal base;
- a vertical inner cylinder secured to the base;
- a vertical outer cylinder, the outer cylinder being movable vertically;
- an uppermost portion to the outer cylinder;
- a pole clamp offset disposed at the uppermost portion of the outer cylinder;
- an offset tube disposed within the pole clamp offset and having an uppermost portion;
- a drill saddle disposed at the uppermost portion of the offset tube;
- means for actuating the outer cylinder to elevate the offset tube and drill saddle for drilling a hole into a concrete ceiling or other overhead surface;
- and
- a dust collection assembly disposed at the drill saddle for evacuating dust as the drill bit drills a hole into the concrete ceiling or other overhead surface.
