| 20090007986 | PNEUMATIC TOOL WITH DUST-BLOWING EFFECT - A pneumatic tool includes a housing formed with an internal blowing flow way and an intake flow way. A blowing nozzle is disposed on a certain section of the housing and connected with a front end of the blowing flow way. A pneumatic cylinder is installed in a cylinder room of the housing. A switch is arranged between the intake flow way and the cylinder room and switchable between an intake position and a blowing position. High-pressure air flows from the intake flow way to the switch. An air conduit is formed on a front end of the switch. A shift button is mounted on the housing and connected with the switch. In use, when the switch is switched to the intake position, the air conduit of the switch communicates with the intake of the cylinder for driving the cylinder. When the switch is switched to the blowing position, the air conduit communicates with the rear end of the blowing flow way, whereby the high-pressure air blows out from the blowing nozzle to blow away dusts and chips. Accordingly, the pneumatic tool is able to blow dust and chips away. | 01-08-2009 |
| 20090032138 | Vacuum attachment for rotary tool - An attachment device for a rotary tool having an output shaft extending from the rotary tool housing is disclosed herein. The attachment device comprises an attachment housing defining a vacuum mouth. A fastening member is coupled to the attachment housing, and is configured to releasably connect the attachment housing to the tool housing. A fan is retained within the attachment housing. The fan is configured for connection to the end of the output shaft extending from the rotary tool such that rotation of the output shaft results in rotation of the impeller. Rotation of the impeller causes air and debris to be drawn into the attachment through the mouth. A debris container is coupled to the attachment housing and is configured to receive the debris drawn into the housing through the vacuum mouth. | 02-05-2009 |
| 20090056832 | DUST COLLECTION CHUTE FOR A JIG APPARATUS - A jig apparatus for aiding in the formation of a variety of mechanically interconnecting structures in workpieces. The jig apparatus may include a base and a template mounting system for adjustably positioning a template with respect to the base. A securing system for securing a work piece in a desired position may be included. An adjustable workpiece mounting fence may also be included for varying the angular orientation of a workpiece to be shaped with respect to a template. Additionally, a collar guide system for a router for utilization with a template may be implemented with a hand held router being implemented for removing material from a workpiece. A router bit positioning system for aiding in establishing a pre-determined bit depth may be included. | 03-05-2009 |
| 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 |
| 20100089497 | Router Dust Collection Assembly - A dust collector is provided for use with a router that is mounted to the underside of a router table. The device serves as a means for collecting dust from both upper and lower surfaces of a cutting tool. The dust collector includes a flexible cup attachable to the underside of the router table, a vacuum hose opening on the cup connectable to a workshop vacuum hose and reducer fitting in combination are attachable to a router table fence and to one of two small openings of a “T” connector fitting on the other end, a vacuum hose attachable to the vacuum hose opening of the cup on one end and attachable to the other of two small openings of the “T” connector on the other end, a larger opening on the “T” connector connectable to a vacuum hose of a workshop vacuum, which in combination. | 04-15-2010 |
| 20100186852 | Vacuum attachment for router table - The vacuum attachment for a router table removes wood chips, dust, and debris during operation of the router. The attachment includes a hollow annular housing adapted for mounting about the router. The annular housing has an upper edge, a lower edge and at least one sidewall, with the upper and lower edges being adapted for sealing engagement with an external surface of the router. At least one vent hole is formed through the annular housing and a vacuum port is formed therethrough, so that a vacuum source connected to the vacuum port is in fluid communication with an interior of the annular housing. When the annular housing is mounted about the router and aligned with an opening in the base of the router, the vacuum source draws debris away from the router and the router table, with environmental air entering the interior through the vent holes. | 07-29-2010 |
| 20100200117 | Suction hood - A suction hood for drillings and drilling dust produced during drilling has a base body ( | 08-12-2010 |
| 20110094625 | Mobile Hood of Wood-Working Table Saw - The present invention relates to woodworking machinery field. More particularly, the present invention relates to Mobile hood of the wood-working table saw. In the present invention, the rear hood and front hood are flexibly connected to the fixing rack of the hoods respectively, and coupled by the combination of guide pin with slot. A tension spring is provided in addition to the hinged connection between the front hood and fixing rack, so that the hood can keep normal working when the saw blade forms a certain angle with the working table, ensure the hood should fall back freely upon the completion of sawing and cover the saw blade for the sake of safety. As the front end of front hood in the present invention does not need extending forward, the table in front of the saw blade can be used to place workpiece conveniently. | 04-28-2011 |
| 20160031054 | DUST COLLECTOR FOR COLLECTING SAWDUST AND WOOD CHIPS - A dust collector for collecting sawdust and wood chips is disclosed. The sawdust and wood chips may be extracted from the conduit and the seat to the upper cylinder and the lower cylinder by the exhaust fan motor. The dust collector may collect the sawdust and wood chips adjacent to the ceiling or higher locations while the seat is at the second mode. And the dust collector may also collect the sawdust and wood chips adjacent to the floor or lower locations while the seat is at the first mode. It is easy to operate to turn around the seat to change to the first mode or the second. And the structure is simplified | 02-04-2016 |
