Abstract
A table miter saw includes a motor assembly and tilt plate assembly holding a blade within a table slot. The blade is mounted to the motor below a table supported by a glide assembly situated within a frame. A handle assembly and the tilt plate assembly are attached to the glide assembly and move the blade longitudinally within the slot. Control knobs operate a shaft to move gears within the tilt plates and change the angle of the blade. A brake lock assembly locks the angle of the blade. The height of the blade is set using a blade height lock in connection with the handle assembly. Mirrored miter fences are connected to the table top with gears for uniform angle change.
Claims12
A saw comprising:
- a table having a table top with a table slot;
- a motor situated below the table top;
- a blade attached to the motor by a shaft;
- a tilt plate assembly attached to the motor for angular adjustment of the blade;
- a handle assembly attached to the tilt plate assembly for height adjustment of the blade within the table slot;
- the tilt plate assembly and handle assembly are attached to a carriage assembly for longitudinal movement of the blade within the table slot for cutting;
- and
- said motor is held by a motor assembly and said tilt plate assembly controls the position of the motor assembly to adjust the angle of the blade and maintains the blade centered within the table slot, and the tilt plate assembly travels on a square shaft during longitudinal movement of the blade, a control knob is attached to the square shaft, and the control knob adjusts the tilt plate assembly to adjust the angle of the blade.

A saw comprising:
- a table having a table top with a table slot;
- a motor situated below the table top;
- a blade attached to the motor by a shaft;
- a tilt plate assembly attached to the motor for angular adjustment of the blade;
- a handle assembly attached to the tilt plate assembly for height adjustment of the blade within the table slot;
- the tilt plate assembly and handle assembly are attached to a carriage assembly for longitudinal movement of the blade within the table slot for cutting;
- and
- the handle assembly includes a handle connected to an elevation lift plate for changing the blade height through vertical movement of the handle;
- a housing structure attached to the handle comprising transmission walls on a left and right side of the handle and said transmission walls are supported by cross-member supports;
- a bracket extends from each transmission wall and is attached to a crossbar of the handle and the crossbar acts as a pivot fulcrum for operation of the handle to lower and raise the blade height;
- transmission wall gears are situated in the transmission walls and move by applying lifting and lowering force to the handle, said gears move the elevation lift plate;
- the elevation lift plate includes a curved shaped channel for supporting a motor height control shaft that operates the height of the motor assembly and blade;
- the transmission wall gears engage teeth on each side of the elevation lift plate and move the elevation lift plate as the handle is raised and lowered;
- and
- posts with channels are provided on ends of the transmission walls for attachment of the elevation lift plate between these posts, and the elevation lift plate travels vertically in the post channels of the transmission walls and moves the motor height control shaft up and down.
