  • Patent number: 8087977
    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.

  • Patent number: 7066691
    Abstract: A hand-held power tool having a multi-speed transmission and a clutch. The multi-speed transmission and the clutch are coupled to one another via a set of interconnecting tabs that are slidingly engaged to one another and secured with pins to inhibit the withdrawal of the tabs from one another. The clutch may include a clutch member, a unitarily formed clutch plate and a plurality of engagement members. The clutch plate includes an annular plate member and a plurality of leg members that extend generally perpendicularly from the annular plate member and which bias the engagement members into engagement with the clutch member. The clutch member may be coupled to an element of the multi-speed transmission, such as to the ring gear of a planetary gear set, so as to reduce the overall size of the power tool.

  • Patent number: 6672402
    Abstract: A motor end cap and output device housing is provided that includes a motor end plate having an output device attachment area and a output device housing having a motor end plate attachment area. The output device attachment area includes a locking tab that mates with a slot portion in the output device housing to interlock the two together. As a result, the motor end plate can be conveniently attached to the output device housing without requiring extra fasteners.
