An object detection system in a saw includes an electrically conductive plate positioned at a predetermined distance from the implement, a detection circuit comprising a transformer, and a single cable connecting first terminal and second terminals of the transformer. The single cable includes a first conductor electrically connected to the first terminal of the winding and to the electrically conductive plate, a second conductor electrically connected to the implement, and an electrical insulator positioned between the first conductor and the second conductor.

Electrical configuration for object detection system in a saw

A guide assembly for aligning a workpiece on a table of a saw device includes a guide member having a first end and a second end along the longitudinal axis that is sized to span a dimension of the table. The guide member includes first and second locking mechanisms located at opposite ends of the guide member that are operable to secure the guide member to the table. The guide assembly further includes a fine adjustment mechanism incorporated into the guide member that is operable when the first and second locking mechanisms are locked. The adjustment assembly includes a side plate movably mounted to the guide member between the first and second ends, and a movement mechanism for moving the side plate relative to the guide member in a direction perpendicular to the longitudinal axis.

Rip fence having micro-adjustment for a power tool

A power tool has a base defining a work surface, a rotary cutting blade extending through an opening in the work surface, a drive motor for imparting rotational movement to the cutting blade and a power train coupled between the drive motor and the cutting blade to transmit rotation movement from the drive motor to the cutting blade. A swing arm assembly carries the cutting blade and is pivotably supported on the base at a pivot axis. In one aspect of the present disclosure, the power tool includes a safety system operable in response to an emergency signal that includes a mechanism for stopping the rotation of the cutting blade, whereby the rotational inertia of the cutting blade is converted after the rotation is stopped to pivoting of the swing arm assembly carrying the blade when the rotation of the blade is stopped.

In one embodiment, a power tool includes a cutting assembly, a sensor system proximate to the cutting assembly, a reaction system operably connected to the cutting assembly, a memory, program instructions stored within the memory, a spatial recognition algorithm stored within the memory, and a processor operably connected to the reaction system, the sensor system, and the memory. The processor is configured to execute the program instructions to detect a man profile within a detection zone associated with the cutting assembly, establish a location of the human profile within the detection zone based upon the detection using the spatial recognition algorithm, determine that an unsafe condition exists based upon the established location, and activate the reaction system.

Power tool with capacitive injury mitigation system

An automatic braking system for a pivoting power tool includes a cutting assembly, a cutting arm supporting the cutting assembly, a hinge supporting the cutting arm through a pivot, a primary braking system operably connected to the cutting assembly, a safety circuit configured to sense an unsafe condition and, in response to sensing the unsafe condition, control the primary braking system to oppose rotation of a blade supported by the cutting assembly, and a damper system operably connected to the cutting arm, the damper system configured to oppose rotation of the cutting arm when the primary braking system is controlled to oppose rotation of the blade.

An automatic braking system for a pivoting power tool includes a cutting assembly, a cutting arm supporting the cutting assembly, a hinge supporting the cutting arm through a pivot, a primary braking system operably connected to the cutting assembly, a secondary braking system operably connected to the hinge, and a safety circuit configured to sense an unsafe condition and, in response to sensing the unsafe condition, (i) control the primary braking system to oppose rotation of a blade supported by the cutting assembly, and (ii) control the secondary braking system to oppose rotation of the cutting arm.

Rotating saw with balanced dynamic braking

A collapsible folding stand for use with a horizontally oriented object such as a portable table saw that is attached to the stand is capable of being manipulated between open and closed positions. In the open position, the top frame is horizontally oriented. In the closed position, the stand is generally vertically oriented. To move the rolling stand from its open position to its closed position, the user needs only to lift the handle and the top frame will then move to its generally vertical closed position where the latching mechanism can then be engaged. The stand has an integrated support leg that can be selectively positioned and locked to provide increased stability for the stand. The support leg has a locking mechanism, which is operated by a single locking lever and can be adjusted to compensate for wear or degree of force needed to lock the mechanism.

An air spring actuated brake assembly for a railway vehicle braking system is provided which comprises an air spring disposed between a mounting member for attachment to the rigid structure of the braking system and a push rod attached thereto for longitudinal movement in an outward direction upon actuation thereof to initiate a braking sequence of the railway vehicle braking system. The air spring actuated brake assembly of the present invention allows for improved control of the brake shoe forces including visual travel measurement indication which is especially desirable during light load conditions. Additionally the air spring actuated brake assembly of the invention allows for the visual inspection and simple replacement of an inflatable spring should an air leak in the actuator occur. Currently used brake assemblies employing cylinder type actuators may be retrofitted with the air spring actuator of the invention.

Universal brake assembly

A tool support structure with an adjustable work support assembly comprises a base and a horizontal support provided on the top of the base. A work support assembly is provided on the horizontal support and is linearly slideable in a vertical direction in relation to the horizontal support. The work support assembly includes a first component and a second component. The first component is configured to be fixed in one of a plurality of first vertical positions with respect to the horizontal support. The second component is also provided on the horizontal support and is linearly slideable in a vertical direction in relation to the first component. The second component is configured to be fixed in one of a plurality of second vertical positions with respect to the first component.

Tool support structure with adjustable end assembly

A locking arrangement for securing a bearing assembly to a male connection member of an articulated coupling apparatus includes an aperture having an outwardly extending beveled portion formed at each end thereof. A race assembly of the bearing assembly has a beveled portion abuttingly engaging a first beveled portion of the aperture and has an inwardly extending recessed portion and a ledge portion disposed adjacent the second beveled portion. The ledge portion at least partially closes the recessed portion and has an inner surface extending from the recessed portion towards the aperture at a predetermined angle. A locking member is disposed in a groove formed by such second beveled portion, the recessed portion and the inner surface of the ledge portion for securing the race assembly within the aperture in combination with the opposed beveled portion formed in the race assembly.
