Disclosed are various embodiments for a table miter saw. The table miter saw allows for cross cuts, bevel cuts, as well as miter cuts and is an improvement over common table saws. The table miter saw includes a platform, orbiting base, and a telescoping assembly that allows for pushing and pulling the saw blade apparatus for mitering safety and ease of use. Additional benefits include the ability to combine multiple carpentry and woodworking tools into one compact device that is easily transferrable to the jobsite.

A device for adjusting tautness of a belt of a motor of a table saw is provided with an adjustment screw, and a pivot. In response to unfastening the adjustment screw, the motor counterclockwise rotates about the pivot to tighten the belt until predetermined tautness is obtained. The adjustment screw fastens to keep the belt at the predetermined tautness. Alternatively, the motor clockwise rotates about the pivot to loosen the belt.

A table saw includes a base assembly; a table assembly mounted on the base assembly and comprising a table and a circular saw blade; a rip fence assembly moveably disposed on one end of the table assembly; and a slide mechanism mounted on the table assembly and including front and rear tracks affixed to front end rear ends of the table respectively; front and rear slides each having one end secured to either end of the rip fence assembly and the other end being open wherein the front and rear slides are moveably mounted on the front and rear tracks respectively; and first, second, third, fourth, and fifth rollers disposed in each of the front and rear tracks. The first, second, fourth, and fifth rollers are at an elevation higher than that of the third roller.

The first, second, fourth, and fifth rollers are at an elevation higher than that of the third roller.

A table saw apparatus is disclosed that includes a main table saw base. A motorized rotatable blade can be disposed on the main table saw base. The table saw apparatus can include a table saw extension assembly. The table saw extension assembly can include at least one extension member, such as an extension rail, pivotally connected to the main table saw base, the at least one extension rail movable to an extended position such that the at least one extension rail extends laterally from the main table saw base, and at least one support leg pivotally connected to the at least one extension rail. The extension assembly disclosed can be retrofitted to existing table saws to provide a foldable laterally extending support assembly for the table saw.

A signal switch for a power tool has a paddle supported by a rocker that extends into a switch housing to pivot an actuating member. A circuit board is attached to a bottom of the switch. At least one micro-switch extends from the circuit board into the switch in position to be actuated by the actuating member depending on a position of the paddle. The circuit board includes a connector that is configured to connect to a cable, such as a ribbon cable. Circuit traces on the circuit board are electrically connected to the micro-switches and the electrical connector. The interior of the switch housing is sealed from the exterior environment so that the mechanical components of the switch are shielded from the environment.

A lubrication system for a saw may include a lubricator that is mechanically linked to a traveling arm of a saw, such as an up-cut saw. Movement of the saw blade through a first path may result automatically in movement of the lubricator through a second path transverse to the first path. This coupled movement may result in a relatively consistent distance between the lubricator and the periphery of the saw blade, especially as compared with a stationary lubricator.

A post 22D may be disposed between holders 22H. Post 22D preferably does not extend from panel 22 as much as holders 22H. Post 22D may have a protrusion 22DD. Pushstick 70 may also have a detent or protrusion 70D extending therefrom. Preferably protrusion 70D moves past protrusion 22DD as pushstick 70 is moved along posts 22HP. Protrusions 70D and 22DD may contact, preventing pushstick 70 from moving along panel 22.

Persons skilled in the art will recognize that protrusions 70D and/or 22DD may engage notches in panel 22 and/or pushstick 70, respectively. Persons skilled in the art will recognize that the interaction of protrusions 70D and/or 22DD can be used instead or in conjunction with the friction-based retaining arrangement, i.e., where friction is created between narrow area 71N and post 22HH, discussed above.

Holders 22H and/or post 22D are preferably integrally molded with panel 22. Accordingly, pushstick 70 may be held unto the panel 22 without requiring any additional parts.

Persons skilled in the art may recognize other additions or alternatives to the means disclosed herein. However, all these additions and/or alterations are considered to be equivalents of the present invention.

Power saws and features for power saws are disclosed. Various features are particularly relevant to jobsite or benchtop table saws, such as a trunnion formed from a shaped tube, an elevation carriage, and an arbor block retention mechanism. Other features are particularly relevant to table saws, hand-held circular saws, track saws, miter saws, and band saws with active injury mitigation technology, such as an electrically isolating gear and an overmolded arbor/gear element.
