Patent number: 10888977Abstract: The present disclosure relates to a suction device including a shell with a chamber, the chamber including an opening. A fan is disposed in the chamber, and a power component for driving the fan to rotate is disposed on the shell. An external fluid source holding an additional fluid is connected to the chamber. The additional fluid of the external fluid source flows into the chamber to occupy a volume in the chamber and at least partially forces a first fluid originally present in the chamber out of the chamber. The fan drives fluids in the chamber to rotate so that a stepped negative pressure is generated in the chamber, with a magnitude of the negative pressure decreasing as a distance to a periphery of the chamber decreases. Thereby, a pressure difference between an inside and an outside of the shell is decreased, decreasing vacuum leakage of the suction device.Type: GrantFiled: March 1, 2019Date of Patent: January 12, 2021Assignee: ZHEJIANG UNIVERSITYInventors: Xin Li, Kaige Shi

Patent number: 6881018Abstract: An apparatus and method for shaping an edge of a tile. The preferred embodiment enables an operator to place a tile between an elevator and a reference plate. The operator snugs the edge of the tile up against a reference plate, and causes the elevator to press the tile towards the reference plate. The reference plate and the elevator are coupled with a transporter. The transporter is moved to maintain the tile in contact the guide surface, whereby the edge is placed into an edge shaping zone of a shaping tool, such as a router bit or a saw. Two or more shaping tools may be placed in series along the guide surface whereby the edge may be successively shaped by each shaping tool in a two or multi-stage process. A motor and a lead screw or a chain may be used to move the transporter and tile.Type: GrantFiled: June 20, 2002Date of Patent: April 19, 2005Inventors: Dennis C. Stoscher, Enrique Rayon

Patent number: 6859988Abstract: One embodiment of the present invention is a compact, low-cost, lightweight, versatile and easy-to-operate, processor-controlled carving and multi-purpose shaping device (“PCCMPS machine”). The PCCMPS machine that represents one embodiment of the present invention is configured, in part, similarly to common, commercially available portable wood planers and ubiquitous laser and ink-jet computer printers, with work pieces fed into the PCCMPS machine in a horizontal direction. The PCCMPS machine includes a motor-powered cutting head that can power detachable bits to drill, cut, shape, and rout a work piece under processor and computer control. The cutting head may be translated, under processor control, back and forth across the surface of the work piece in a direction perpendicular to the direction in which the work piece is fed into the PCCMPS machine and moved by motor-powered rollers.Type: GrantFiled: July 25, 2002Date of Patent: March 1, 2005Assignee: LHR TechnologiesInventors: Christopher Scott Lovchik, James David Jochim, Dennis Girard Lawler

Patent number: 6792984Abstract: Devices and systems for adjustably positioning a router on a work surface such as a router table are disclosed. A router lift in accordance with an exemplary embodiment of the present invention includes a top plate having an opening therethrough adapted to receive a router bit, one or more columns extending from the bottom surface of the top plate, a router housing operatively coupled to the one or more columns, and a power screw threadably connected through the top plate and housing. The housing may include a generally circular portion defining a cylindrical aperture that can be adjusted to accommodate for various router sizes. The housing may also include cooling fins to dissipate heat generated from the router. A calibration dial having a scale that can be used to measure elevation of the router and router bit relative to the top plate may also be used.Type: GrantFiled: June 19, 2002Date of Patent: September 21, 2004Assignee: Bench Dog, Inc.Inventor: Norston Fontaine

Patent number: 6752572Abstract: A circle cutting accessory for use with a generally cylindrical powered rotary hand tool with an output shaft at one end thereof, the tool having a second accessory attached to the one end, with the second accessory having at its distal end an outwardly extending flange with a first predetermined diameter around a substantial portion of the circumference thereof, the circle cutting accessory including a generally flat housing for receiving and supporting the second accessory and the rotary hand tool. The housing has an upper support surface with an aperture through which a cutting tool attached to the output shaft can pass. The circle cutting accessory further includes a generally horizontal elongated arm mounted to the housing and extends outwardly from the housing. A circle center and sizing elongated member is slidably attached to the arm and has a centering pin extending downwardly therefrom at one end portion.Type: GrantFiled: June 7, 2002Date of Patent: June 22, 2004Assignee: S-B Power Tool CorporationInventors: Mark S.

Publication number: 20030159758Abstract: A stand is made up of two channel shaped sides. There is a removable top that has holes drilled in it so a router with router bits of different diameters and shapes, such as round-nosed and straight router bits or heads, can be attached. There is a removable wood guide having a front with two wood guide sides attached to it. The electric router is the power source for the cutter. The round nose bit cuts the wood ends to form tenons of different diameters and shapes, such as radius, chamfered (tapered) or square-shouldered tenons. The top will be a flat surface with holes that will support a router and attach to the sides. The two channel shaped sides will include holes for attaching a top, securing it to a work bench, and attaching wood guides. The fronts will have different diameter holes, and will attach to wood guide sides. The wood guide sides will have a slot where a bolt can pass through to attach wood guides to channel sides.Type: ApplicationFiled: February 26, 2003Publication date: August 28, 2003Inventor: Leslie G. Smith

Patent number: 6568442Abstract: The invention is for a method for removing at least a portion of a floorboard from a plurality of floorboards installed on a surface base. The method comprises isolating the floorboard or portion thereof for removal and removing a central portion of the isolated floorboard so as to leave a pair of elongate lateral strips, a pair of end portions and a substantially central open space. A routing bit having a shaft and a blade portion is then located such that the blade portion is parallel to, and cuts in, the same plane as the surface base on which the floorboard is installed. The blade is placed beneath the lateral strips and/or end portions so as to remove all material between a lower surface of the floorboard and the base upon which it is installed. The invention is also for a routing bit for removing a floorboard from the base upon which it is mounted.Type: GrantFiled: November 28, 2001Date of Patent: May 27, 2003Inventor: Joseph Anthony Meugniot
