Abstract:
A support frame for a power tool includes a top configured to support a table top and a bottom arranged opposite and parallel to the top. The bottom is configured to support the support frame on a surface when the support frame is in a first position. The support frame further includes a side arranged between the top and the bottom and configured to support the support frame on the surface when the support frame is in a second position. When the support frame is in the first position and the second position, the table top is spaced apart from the surface.
Abstract:
An improvement for a power tool having a motor-driven working tool for performing an operation on a workpiece includes a material sensor positioned to sense the workpiece prior to operation by the working tool. The material sensor is configured to determine a material property of the workpiece and to generate a signal in response thereto. A processor coupled between the material sensor and the motor is configured to control the motor in response to the signal generated by the material sensor.
Abstract:
A power tool support system includes a base, a table top supported on the base and having a generally planar support surface, and a tool support assembly. The tool support assembly includes an arch-shaped support member attached to a first side portion of the base and which extends arcuately from the first side portion toward a second side portion of the base. An arch slide mount is slidably supported on the arch-shaped support member and positionable at a plurality of different angular positions along the arch-shaped support member. The tool support assembly includes a tool mount coupled to the arch slide mount and configured to releasably retain a cutting tool at a predetermined orientation with respect to the table top. The power tool support system may include a height adjustment assembly and a horizontal guide assembly and be configured to support one or more types of cutting tools.
Abstract:
A pneumatic cylinder associated with a table saw includes a housing, a charge, and a piston assembly. The housing defines a cavity and is supported by a frame of a table saw. The charge is located within the cavity. The piston assembly is located within the cavity and includes an attachment structure engaged to the housing and a piston head releaseably connected to the attachment structure and in response to activation of the charge the piston head is configured to (i) disconnect from the attachment structure, and (ii) move away from the attachment structure. A swing arm of the table saw is configured to move from a raised position to a lowered position in response to movement of the piston head.
Abstract:
A heated garment system in one embodiment includes a jacket, a wiring circuit embedded within the jacket and configured to generate heat, a battery assembly configured to removably couple with the wiring circuit, the battery assembly including a power button for selectively applying power to the wiring circuit, and a battery holder configured to removably receive the battery assembly.
Abstract:
A rip fence (12) for a table saw (10) includes a frame having a front portion and a rear portion. A front clamping lever (48) is pivotably supported in the front portion of the frame for movement between a clamped and an undamped position. A handle (44) is pivotably supported in the front portion of the frame for movement between a locked and an unlocked position. The handle (44) includes a lever portion (58) that engages the front clamping lever (48) and moves the front clamping lever (48) from the undamped to the clamped position when the handle (44) is moved from the unlocked position toward the locked position. A rear clamping lever (88) is attached to the rear portion of the frame and movable between a clamped and undamped position. When the front clamping lever (48) is moved to clamped position by the lever portion (58) of the handle (44), continued movement of the handle (44) to locked position results in the handle (44) pulling the rear clamping lever (88) from the undamped to the clamped position.
Abstract:
A guard device for a saw system (100) in which the table saw is not operated without a saw blade guard (112), unless a user intends to make a non-through cut in a workpiece (114). The guard device, in one embodiment, determines whether an adjusted saw blade height (SB1) corresponds to a thickness of the workpiece (114) to be cut and prevents the tool or motor (105) driving the saw blade (102) from operating if the saw blade (102) is adjusted too high, in order to improve work conditions.
Abstract:
A leveling and plumbing device that incorporates: a frame, a body pendulously mounted relative to the frame, a laser module fixed relative to the body so as to be mounted for movement with the body, a beam divider, fixed relative to the laser module as to be mounted for movement with the body, that receive the green light emitted from the crystal and divides the light into at least two beams, including a first beam and a second beam, and first and second line lens, fixed relative to the laser module so as to be mounted for movement with the body, disposed in the path of the first and second beam respectively.
Abstract:
A generally C shaped power tool handle (10) has two ends (14, 16) for releasably engaging the power tool housing (12), with a gripping portion (22) between the ends. One of the handle ends (14) has a release lever (34), while the other of the ends (16) has an attachment arm (48). The release lever (34) has an actuating end (44) operable to detach the handle from the tool housing (12). Additional power tool handle embodiments are directed to a tool handle that has a gripping layer (108) and a storage compartment (100) in the handle, with a pliable lip (106) in the handle for resisting movement of stored tools.
Abstract:
A method for secure access control to a power tool enables secure access to an embedded computing device in the power tool from a web application in another computer that is connected to the power tool via a USB or other suitable peripheral data connection in a workshop environment. The access control enables authorized parties to perform repair and diagnostic procedures on the power tools based on specific user roles while denying access to unauthorized parties.
