Abstract: A shaft coupler, a tool and a method of assembling a tool. The shaft coupler may generally include substantially identical coupling members operable to couple two shaft segments of a tool. The shaft coupler may include a first coupling member including a first body having a first coupling end and an opposite first shaft end defining a first opening configured to receive a first shaft segment; and a second coupling member including a second body having a second coupling end and an opposite second shaft end defining a second opening configured to receive a second shaft segment. The first coupling member and the second coupling member may be identical. The first coupling end may be configured to engage the second coupling end to selectively couple the first coupling member to the second coupling member and, thereby, the first shaft segment to the second shaft segment.

Abstract: A fogger includes a blower tube having a passageway, a fan configured to rotate to generate an airflow through the passageway, a reservoir configured to hold a volume of fluid and a volume of air, an air pump in fluid communication with the fluid in the reservoir, a motor configured to drive the fan and the air pump, an atomizing valve, a dispensing line fluidly coupling the atomizing valve to the passageway, a liquid tube fluidly coupling the fluid in the reservoir to the atomizing valve, and an air escape line fluidly coupling the air in the reservoir to the atomizing valve. In response to the air pump providing a stream of compressed air to the reservoir, air moves through the air escape line from the reservoir to the atomizing valve, such that fluid is drawn through the liquid tube and into the atomizing valve to be atomized.

Abstract: A leaf blower to be worn by a user. The leaf blower including a frame having a back plate defining a back plate plane and a blower system coupled to the frame. The blower system includes a motor having drive shaft, the drive shaft defining an axis, and the axis forms an angle with respect to the back plate plane between about 5 degrees and about 35 degrees.

Abstract: A cutting tool has a cutting head, a motor and a transmission means drivable by the motor. The cutting head comprises first and second cutting members, wherein the first cutting member is pivotably moveable with respect to the second cutting member. At least the first cutting member is drivable by the transmission means between a first angular position with respect to the second cutting member and a second angular position with respect to the second cutting member, in which a space between the respective cutting blades is closed. The transmission means is a bevel gear on the output shaft of a gearbox which conveys drive power from the motor to the drive gear. The bevel gear directly engages a bevel wheel member connected to the first cutting member and which swivels with the first cutting member about the same swivel point. A controller comprises main, first and second switches which control the motor to move the first cutting member (movable blade).

Abstract: A system and method for a double source battery charger of an engine-generator. The double source battery charger of the engine-generator includes an electric starter and a battery. The electric starter is selectively energized by the battery to start an engine of the engine-generator. The double source charger maintains the battery at a desired charge such that the battery has sufficient charge to energize the electric starter. The double source battery charger is selectively coupled to one of two power sources to charge the battery: an alternator of the engine-generator and an external AC source, such as a standard 120 Volt or 240 Volt wall outlet. As a result, the battery is charged by either power from a wall outlet or, if the generator is running, by power provided from the alternator.

Abstract: A reciprocating power tool includes a reciprocating cutting mechanism arranged to be driven by a motor via a driving assembly. The driving assembly includes a resilient arrangement arranged to be charged when the cutting mechanism is driven by the motor. When the drive from the motor is terminated, the resilient arrangement is arranged to reverse the cutting mechanism from the direction of the drive from the motor.

Abstract: A snow thrower comprising a frame, a handle coupled to the frame, a chute coupled to the frame and rotatable between a plurality of positions about a chute axis, and a chute control assembly. The chute control assembly comprises an actuator assembly including an actuator movable between a plurality of positions, a rotatable flexible cable having first and second ends, and a gear assembly comprising at least one gear. The first end is coupled to the actuator assembly in a manner that causes the cable to rotate when the actuator is moved between the plurality of positions. The gear is coupled to the second end in a manner that causes the gear to rotate when the cable rotates. The chute is coupled to the gear in a manner that causes the chute to rotate about the chute axis when the gear rotates.

Abstract: A hand held blower/vacuum device includes an impeller mounted in a scroll housing and a handle by which the device may be suspended and which is rotatably mounted to turn between vacuum and blower positions. In both of the blower and vacuum positions a longitudinal axis of the grip generally lies in an upright plane that passes through a center of gravity of the device, and the grip is disposed above the center of gravity, such that the device hangs below the grip in different balanced orientations in the blower and vacuum positions.

Abstract: A spray gun for use with a pressure washer including a body with a nozzle and a handle. A trigger is coupled to the body and pivotable relative to the handle. A conduit extends through the nozzle and defines a fluid outlet. A valve housing defines a fluid inlet and includes a first chamber, a second chamber, and a valve seat including an aperture. A piston includes a valve member moveably disposed within the first chamber and a linkage extending between the trigger and the valve member. A biasing mechanism is positioned within the chamber and biases the valve member such that at least a portion of the valve member is retained within the aperture. Actuation of the trigger displaces the valve member and the linkage against the bias of the biasing mechanism to selectively allow fluid to flow from the inlet to the outlet through the aperture.
