20090181604 | DUST SHROUD FOR ROTARY TOOLS - A dust shroud for rotary tools includes a front half and a back half which are attachable together along an axis thereof to form a dust shroud. The dust shroud is mountable to a rotary power tool after mounting a mandrel in the power tool, and includes one or more openings to allow a person to lock the shaft of the tool while the dust shroud is mounted thereto to allow a person to change a worn out abrasive pad. The dust shroud is particularly suited for use with die grinders and similar rotary tools. | 07-16-2009 |
20090181605 | DUST SHROUD WITH ADJUSTABLE MOUNTING MECHANISM - A universal dust shroud includes mounting brackets held above the shroud body by springs. The brackets move radially and vertically relative to the body to accommodate different angle grinders, and allow vertical movement of the shroud body relative to the grinding disk while using the grinder to allow the user greater control over the angle grinder. | 07-16-2009 |
20090181606 | VACUUM SHROUD FOR USE WITH DRILLING TOOLS - A flexible vacuum shroud provides an improved seal to the work surface and allows for use on curved surfaces. The shroud incorporates support structures around the cutting tool hole which improve performance with different cutting tools and which prevent collapse of the shroud. | 07-16-2009 |
20090183377 | DUST SHROUD FOR CIRCULAR SAWS - A circular saw dust shroud extends around the open portion of the blade guard to enclose the saw blade. The dust shroud provides improved dust collection while still allowing unimpeded use of the saw. | 07-23-2009 |
20090183800 | DUST SHROUD FOR GAS POWERED CIRCULAR SAWS - A dust shroud for gas powered circular saws allows for mounting to a circular saw and for use therewith out hindering the use of the saw. The shroud does not interfere with the ability to operate the saw or set the saw on the ground, and effectively collects dust and debris without reducing the depth of cut. | 07-23-2009 |
20090186559 | DUST SHROUD WITH ACCESS HATCH RETENTION MECHANISM - A vacuum shroud for an angle grinder includes a removable hatch for grinding in a corner and provides a storage location on the shroud for the hatch in order to encourage use of the hatch when not grinding in a corner. | 07-23-2009 |
20090241283 | TOOL OPERATED SWITCH FOR VACUUMS - A vacuum control system allows the vacuum to be turned on and off automatically based on the operation of an associated power tool. The vacuum is able to run at full power without sacrificing power to the power tool itself. Additionally, a pneumatic power tool may be used to control the operation of the vacuum. | 10-01-2009 |
20100285729 | ANGLE GRINDER DUST SHROUD WITH UNITARY ADJUSTABLE MOUNTING COLLAR - A universal dust shroud includes a unitary mounting bracket on top of the shroud body. The bracket includes a plurality of collar sections attached to the body via a āZā shaped joint which allows the collar sections to move radially inwardly and outwardly relative to each other to accommodate different angle grinders. The bracket may include slots formed at the base of the bracket. The slots allow air to flow in through the slots, out past the grinding disk, and to the vacuum port. As such, the slots can aid in cooling the grinder output and bearings, and helps keep dust and debris away from the bearings in order to extend the life of the grinder. | 11-11-2010 |
20100313867 | UNIVERSAL DUST COLLECTION SHROUD FOR HIGH SPEED GAS POWERED SAWS - A universal dust shroud is mountable to many high speed gas powered concrete cutting saws while remaining strong and stable. The dust shroud is adjustable to properly fit the saw and effectively collect dust and debris. | 12-16-2010 |
20110021121 | ANGLE GRINDER DUST SHROUD WITH SLIDEABLE ACCESS HATCH - A dust shroud for an angle grinder includes an access hatch which slides along the shroud body to selectively expose an edge of a grinding disc to allow grinding into a corner. The hatch remains attached to the shroud body in both the open and closed position, making the hatch easier to use and less likely to become lost, resulting in increased worker compliance in properly using the hatch. | 01-27-2011 |
20110192262 | CUTOFF SAW AND STAND WITH INTEGRATED DUST FILTRATION SYSTEM - A cutoff saw and filtration system provides convenient multi-stage filtration for a cutoff saw. The filters are effective in capturing the dust and debris created by the saw without becoming clogged. The filters may be easily cleaned and serviced. | 08-11-2011 |
20120142263 | Dust Shroud for Power Tools - A dust shroud assembly for a power tool includes a shroud portion, a barrel, and a helical spring. The barrel includes an upper portion slidably received within a first end portion of the shroud portion. The barrel defines a helical channel. The helical spring is at least partially rotatably engaged with the helical channel and rotationally fixed with respect to the shroud portion. The helical spring is configured to bias the barrel outwardly from the first end portion. | 06-07-2012 |
20130055577 | RECIPROCATING SAW DUST SHROUD - A dust shroud for reciprocating saws has a shroud body with bristles, a vacuum port and an attachment collar attached to the shroud body. The shroud has a slot formed through the collar and shroud body and is expandable and collapsible to fit different sizes of reciprocating saws. | 03-07-2013 |
20140215752 | ASH VACUUM AND SEPARATOR WITH FILTER CLEANING DEVICE - A vacuum system includes a filter cleaning mechanism which allows the filter to be cleaned without removal from the vacuum. This mechanism can include a carrying handle which is biased against the lid by a spring. The handle may be released from a vertical position, causing the handle to forcefully strike the lid and dislodge debris from the filter. The vacuum may include a spark arrestor disposed around the filter. The spark arrestor encloses the filter and surrounds the filter sides with a metal screen. The spark arrestor has holes formed in the bottom around the outer perimeter of the filter so that debris which is dislodged from the filter falls through the holes and into the vacuum canister. | 08-07-2014 |
