20080289469 | Sawing angle sensing device for a sawing machine - A sawing angle sensing device for a sawing machine includes at least a support frame, a sensing head, an induction plate and a display module. The support frame has one side secured on the rotatable base of a sawing machine for rotating and swinging together with the rotatable base. The sensing head is fixed at the other side of the support frame and actuated to swing by the support frame. The induction plate is disposed at a corresponding location of the sensing head, having its surface provided with a successive signal set made of plural induction members. Thus, the sensing head can always correspond to the induction members and sense the shifting signals of the induction members. The display module is provided with a microchip set to receive signals and collate the signals and then output an angle tilt signal to be shown on a digital display. | 11-27-2008 |
20090199689 | MITER ADJUSTMENT ASSEMBLY FOR A SAW - A power tool includes a base, a table supported by the base for pivoting movement about an axis, a coarse adjustment assembly between the base and the table, and a fine adjustment assembly between the base and the table. The fine adjustment assembly includes a rotating member supported by one of the base and the table, and an engagement surface provided by the other of the base and the table. The rotating member is selectively engageable with and rotatable along the engagement surface to finely adjust the angular position of the table relative to the base. The angular position of the table relative to the base is coarsely adjustable using the coarse adjustment assembly when the rotating member is disengaged from the engagement surface. The fine adjustment assembly disengages the coarse adjustment assembly and maintains the coarse adjustment assembly disengaged when the rotating member is engaged with the engagement surface. | 08-13-2009 |

The height and bevel adjustment wheels are disposed at the front of the base assembly. The position of the height and bevel adjustment wheels relative to the front of the base assembly does not change regardless of the blade height and bevel angle. | 01-14-2010 |
20100263511 | POWER TOOL CUTTING APPARATUS - The invention relates to apparatus for providing for the powered cutting of a workpiece, typically in the form of a planar or sheet material. The apparatus includes a rotatable blade to cut the workpiece and the blade is mountable such as in a first mode of use to be capable of being held in a fixed position in which the workpiece is moved past the blade, and a second mode of use in which the blade is moved with respect to the workpiece to cut the same. The workpiece is mounted on a base and the blade is mounted with respect to the base via one or more slide members ( | 10-21-2010 |
20100294100 | System for Forming a Miter Joint - The present invention is directed toward a system for forming miter joints including a miter saw and an angle gauge. The miter saw includes a platform with a kerf slot and a pair of arcuate slots. Each arcuate slot includes an associated rail located on the underside of the platform. A fence is coupled to each of the rails such that the fence may be pivoted with respect to the platform. The angle measurement tool is a one-handed tool including spring loaded paddles that measure the angle between intersecting surfaces. The angle measurement tool connects to the miter saw to permit the transfer of the measured angle to the fences. | 11-25-2010 |
20110041666 | CUTTING DEVICES - A cutting device includes a positioning mechanism for positioning a cutting unit at a plurality of tilt angles including a first tilt angle and a second tilt angle in a left direction and/or a right direction. The first tilt angle is larger than the second tilt angle. A setting state for the first tilt angle is reset to a setting state for the second tilt angle when a positioning state at the first tilt angle is released. | 02-24-2011 |
20110100183 | Table saw blade height and angle adjustment mechanism - A mechanism for automatically adjusting the height and angle of a table saw blade is disclosed. The table saw comprises a working surface through which the saw blade protrudes to a certain height. An arbor assembly is connected to the bottom of the working surface of the table saw by means of pivot shoes. The mechanism adjustment disclosed comprises two motors and shafts coupled to the arbor assembly that allows the user to adjust the height and angle of the saw blade independently as required for the dimension of the material to be cut or the desired angle of the cut. | 05-05-2011 |
20110232449 | SAWING MACHINE HAVING A MITER ANGLE ADJUSTMENT ASSEMBLY - A sawing machine having a miter angle adjustment assembly includes a machine base, a worktable rotatably connected to the machine base and rotatable about an axis, a cutter unit mounted to the worktable, a tightening member to lock movement of the worktable relative to the machine base and a driving device set. The driving device set includes a driving member pivotally mounted to the worktable and an eccentric member coaxially rotatable with the driving member to move the tightening member. The eccentric member is controllable by the driving member to rotate between a first position and a second position to move the tightening member into engagement with or away from the machine base. | 09-29-2011 |
20120036976 | GUARD SYSTEMS FOR TABLE SAW - A table saw is disclosed. The table saw includes a table top including an opening configured to receive a saw blade, a blade case positioned under the table top, the blade case including an interior portion with the saw blade partially positioned within the interior portion, the blade case configured to move relative to the table top, a motor coupled to the saw blade and configured to move relative to the table top, the saw motor configured to rotate the blade about a blade axis, and at least one moveable guard member positioned between the table top and the blade case, the at least one moveable guard member providing an obstruction to the interior portion of the blade case, and the at least one moveable guard member configured to pivot about a pivot axis when the motor is moved up or down or tilted relative to the table top, wherein the pivot axis is substantially perpendicular to the blade axis. | 02-16-2012 |
20130098217 | Table Saw - A table saw has a base assembly, a table assembly supported by the base assembly, and a saw assembly supported by at least one of the table assembly and the base assembly.
