A table saw includes a height adjustment wheel including a threaded shaft; a blade suspension mechanism secured to a lock crank; a rod secured to both the blade suspension mechanism and a bottom of the cutting surface; an electric motor including a driving shaft and a link extending forward to secure to the blade suspension mechanism; a circular saw blade operatively connected to the driving shaft; first and second mounting plates each secured to the link and including a slanted slot element; and an interconnection including two end holes moveably disposed in the slot elements of the first and second mounting plates respectively, and an intermediate threaded hole secured to the threaded shaft. A rotation of the height adjustment wheel moves the saw blade up or down.

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. The saw assembly includes a saw blade extending through the table assembly. The base assembly has at least one tube connected to the table assembly.

A table saw includes a table, a saw unit movably coupled underneath the table, a riving knife extending through the table, and a quick-release assembly selectively coupling the riving knife to the table. The quick-release assembly includes a mounting plate coupled to the table and a clamping plate movable relative to the mounting plate between a clamping position, in which the riving knife is clamped between the mounting plate and the clamping plate to secure the riving knife to the table, and a release position, in which the riving knife is releasable from the table. The quick-release assembly further includes a pin coupled for movement with the clamping plate and a handle pivotably coupled to the pin. The pin has a cam portion engageable with the saw unit. The clamping plate is movable between the clamping position and the release position in response to pivoting movement of the handle.

A power tool apparatus includes at least a power tool, a table, a bevel adjustment assembly, and a bevel stop. The table includes a work surface and a panel portion. The panel portion has an exterior surface. The bevel adjustment assembly is configured to move to various positions along a pathway of the panel portion. The tool is configured to move to various bevel angles as the bevel adjustment assembly moves to the various positions. The bevel stop is disposed on the exterior surface. The bevel stop includes a stopper that is configured to move to a blocking position in which the stopper obstructs a first section of the pathway to stop the bevel adjustment assembly from moving beyond a first position of the pathway along a first direction such that the saw blade is bounded at a first bevel angle corresponding to the first position. The stopper is configured to move to an unblocking position in which the stopper does not obstruct the first section of the pathway such that the bevel adjustment assembly is permitted to move to a second position that is further along the pathway in the first direction than the first position such that the saw blade is not bounded at the first bevel angle and permitted to move to a second bevel angle corresponding to the second position.

A table saw includes a table that defines a saw blade slot and a first trunnion member defining a first axis point of a bevel pivot axis, wherein the first trunnion member supports a saw carriage. The table saw further includes a first mounting arrangement configured to fix the first trunnion member to the table in an engaged state of the first mounting arrangement, and a horizontal axis alignment arrangement configured, in a disengaged state of the first mounting arrangement, to inhibit lateral movement of the first trunnion member and to allow vertical movement of the first trunnion member.

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.

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 saw assembly for cutting a workpiece is disclosed. The saw assembly includes a platform for supporting the saw assembly on a surface. The saw assembly further includes a table assembly having a saw for cutting the workpiece and a table surface for supporting the workpiece during cutting. The table assembly is pivotably coupled to the platform and is adapted to pivot relative to the platform to position the table surface at an inclination relative to the surface.

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.
