Abstract: A power tool including: a housing including a motor housing portion and a handle portion; a drive mechanism supported within the housing, the drive mechanism including an electric motor and a transmission coupled to an output shaft; an electronic component configured to provide power to the electric motor; a plurality of walls disposed within the housing, the plurality of walls including a venturi wall section having a first wall portion, a second wall portion, and a constricted wall portion extending between the first wall portion and the second wall portion; and wherein the constricted wall portion includes a constricted wall diameter less than a first wall diameter of the first wall portion and a second wall diameter of the second wall portion.

Abstract: A power tool including a housing including a motor housing portion and a handle portion extending from the motor housing portion. The power tool further includes a motor disposed within the motor housing portion, a trigger located on a front side of the handle portion, and a dial assembly partially positioned within the housing above the trigger. The trigger is moveable axially along a trigger axis. The dial assembly is configured to change a torque setting of the power tool. The dial assembly includes a case coupled to the housing, a dial circuit board positioned within the case, and a dial surrounding the case. The dial circuit board includes a Hall effect sensor. The dial is rotatable about a dial axis orthogonal to the trigger axis and includes a magnet aperture. The magnet aperture is configured to receive a magnet, which is rotatable with the dial.

Abstract: A power tool system including a power tool base having a main body, an electric including an output, and a tool-side attachment mechanism coupled to the main body, the tool-side attachment mechanism having a tool-side locking lug and a tool-side slot adjacent the tool side locking lug. An accessory is configured to be selectively coupled to the power tool base and includes an accessory-side attachment mechanism having an accessory-side locking lug and an accessory-side slot, the accessory-side locking lug selectively engagable with the tool side slot and the accessory-side slot selectively engagable with the tool-side locking lug, a gear arrangement configured to be operably coupled to the output of the electric motor to receive torque from the electric motor, and a tool holder configured to be driven by the gear arrangement. The accessory-side attachment mechanism selectively engages the tool-side attachment mechanism to axially couple the accessory to the power tool base.

Abstract: A tool comprises a housing, an electric motor positioned in the housing, and a drive assembly including an output shaft having a driving end portion. The output shaft extends from the housing such that a tool element for performing work on a workpiece is attachable to the output shaft. A retainer assembly is positioned about an outer surface of the driving end portion. The retainer assembly has a proximal end adjacent to the housing.

Abstract: A vehicle comprising a rotatable wheel (e.g., three rotatable wheels), a forward drive mechanism including a forward drive motor (e.g., an internal combustion engine), and a reverse drive mechanism. The reverse drive mechanism includes a reverse drive motor (e.g., an electric motor) adapted to move the chassis in the rearward direction, and a reverse drive control programmed to inhibit operation of the reverse drive mechanism when the forward drive motor is off. In one embodiment, the vehicle includes a battery for operating the reverse drive motor, and the reverse drive control is programmed to inhibit operation of the motor when a characteristic of the battery (e.g., an output voltage) falls below a threshold. The vehicle can further include a temperature sensor for the reverse drive motor. In this embodiment, the reverse drive control is programmed to inhibit operation of the reverse drive motor when the temperature of the motor exceeds a threshold.

Abstract: A riser for a motorcycle having a front wheel coupled to a steering assembly that is movable to pivot the front wheel and steer the motorcycle. The riser includes a first portion that is adapted to be coupled to the steering assembly and defines an axis. A carrier is adapted to engage the handlebar such that the carrier and the handlebar are fixedly attached to one another. The carrier is movably coupled to the first portion such that the carrier is movable along the axis.

Abstract: An improved trailer tongue jack including an outer tube and an inner tube which is slidable within the outer tube. The lower end of the inner tube carries a terrain engaging member, such as a caster wheel or sand shoe. A nut is mounted within the inner tube and is threaded on a screw and the upper end of the screw carries a bevel gear which meshes with a second bevel gear mounted on a handle. The bevel gears are supported within a polymeric cup mounted in the upper end of the outer tube and the cup also serves to rotatably support the handle as well as the upper end of the screw and further functions, along with a thrust washer, as a thrust bearing for the screw. The jack also includes an improved locking mechanism for locking the jack in either a vertical or horizontal position. A U-shaped swivel bracket is secured to the outer surface of the outer tube and the lower end portion of a locking member is mounted for movement within aligned openings in flanges of the swivel bracket.
