Black & Decker Inc. - Newark DE

International Classification:

B23B 45/02

US Classification:

173170, 173216, 173217

Abstract:

An angle grinder is provided including a rotating handle configuration allowing the handle of the angle grinder to be locked in different positions relative to the angle grinder housing. A switch mounting configuration is provided for simplifying the assembly of the switch device.

US Classification:

361 33, 361 23, 361 1, 318434, 388819, 408124

Abstract:

A motor control module designed to control operation of a plurality of different motors in a plurality of different tools a power tool uses an electronic clutch in the module in conjunction with a mechanical clutch in the tool to protect the tool against an overload event. The module is adapted to implement methods to provide aural and/or tactile feedback to a tool user as a warning of an impending or current fault condition in the tool. The module can prevent power from inadvertently turning on either after an overload event has cleared with the tool plugged in and its power switch on, or after plugging in the tool within the power switch on. The control module is adapted to provide torque control for the power tool, to estimate tool motor temperature and to inform a tool user when a servicing need in the tool is required.

US Classification:

451359, 451344, 451353

Abstract:

An angle grinder is provided including a trigger assembly for selectively actuating the angle grinder. A particle separation assembly is provided for the removal of any dust, particle, or artifacts that may have entered into the housing of the angle grinder. A brush biasing system is also provided to ensure proper and efficient operation of the motor of the angle grinder. An overload monitoring system is included to monitor the loading on the motor. A clutch mechanism is also included to prevent overloading on the motor of the angle grinder. A gear wheel lock mechanism is also provided to prevent the wheel spindle from rotating during installation or removal of a grinding wheel on the wheel spindle. An anti-locking flange system is also included to prevent the over-tightening of the flanges and the grinder wheel during the operation of the angle grinder. A gear case labyrinth feature is also provided.

Inventors:

William M. Gallagher - Toms River NJ, US

International Classification:

B25B 7/02
B25B 1/04
B23Q 3/02

US Classification:

81426, 269 6, 269 96, 81420

Abstract:

An offset force clamp is provided for securely holding a workpiece to a table of a cutting machine. The clamp is a modified clamping pliers having a planar base jaw and an elongate upper jaw oriented perpendicular to one another. The base jaw is preferably mounted fixedly to a first handle of the clamp and the upper jaw is preferably mounted pivotably to a second handle of the clamp. The base jaw is configured to engage the table as the upper jaw applies an offset force to hold the workpiece so that the clamp is not cut during the cutting operation.
