A wet/dry vacuum that is configured to be powered by a DC power source.

AC/DC hand portable wet/dry vacuum having improved portability and convenience

A cordless power tool has a housing which includes a mechanism to couple with a removable battery pack. The battery pack includes one or more battery cells as well as a vent system in the battery pack housing which enables fluid to move through the housing. A mechanism is associated with the battery pack to dissipate heat from the battery pack.

Battery cooling system

A tool chuck may include a shaft supporting chuck jaws. The shaft may provide a first transmission power path for rotationally driving the chuck jaws. The shaft may have a through hole. A chuck actuating mechanism may be provided in the through hole. The chuck actuating mechanism may provide a second transmission power path for opening and closing the chuck jaws.

Tool chuck with power take off feature

A wet/dry utility vacuum with a canister, a powerhead assembly with a fan, a shut-off device that prevents the fan from drawing liquids into the fan inlet when a volume of the liquid in the canister exceeds a predetermined volume. The powerhead assembly includes a controller that permits the utility vacuum to be operated in a desired power mode so that the user may employ either an AC power source or a DC power source, such as a battery pack, for example. In some applications, the battery pack may be interchangeable with the battery packs of various cordless tools, including drill/drivers and saws. A tool set and a method for operating a battery-powered tool set are also provided.

A tool set with a battery pack, a power tool and a utility vacuum. The power tool includes a receptacle assembly for detachably coupling the battery pack to the power tool. The utility vacuum has a canister, a powerhead assembly, which is coupled to the canister and has a fan, a motor for providing rotary power to the fan, and a power supply for distributing electrical power to the motor, and a shut-off device that prevents the fan from drawing a liquid into the fan inlet when a volume of the liquid in the canister exceeds a predetermined volume. The power supply includes a receptacle assembly for detachably receiving the battery pack. The battery pack may be selectively coupled to either of the power tool and the utility vacuum to provide a source of electrical power thereto. A method for operating a battery-powered tool set is also provided.

System having a power tool and an AC/DC hand portable wet/dry vacuum that share a battery pack

A tool and method for winding and forming a field coil for field assembly, such as a stator, includes separable tool halves defining a winding cavity therebetween. The winding cavity receives magnet wire that is wound therein, such as by rotating the tool or a winding nozzle. The magnet wire generally conforms to the shape of the winding cavity such that when the tool halves are separated, a field coil having a net shape is produced. Once the magnet wire is sufficiently deposited within the winding cavity, wires of the coil may be bonded together either through a resistive heating process such as by passing an electrical current through the coil or through other heating or chemical bonding methods to thereby maintain the net shape of the field coil once it is removed from the tool.

Tool for manufacturing coils for dynamoelectric machines and method therefor

A chuck includes a pair of jaws which are located within an axial opening of a body for receipt of a shank of a bit therein. A roller is located in a slot of the body and can be pressed into the shank of the bit to clamp the shank between the jaws and the roller. A sleeve is biased and structured to normally urge the roller into the shank-pressing position, and is movable relative to the body to facilitate removal of the shank from the chuck
