Abstract: A portable power driven system has a battery started engine and a receptacle for receiving a battery pack. An arm is disposed on the portable power driven system and is movable between a locked position where it blocks the battery pack from being removed from the receptacle and an unlocked position where it does not block the battery pack from being removed from the receptacle.

Abstract: A portable power driven system has a manually movable frame. In one example, an internal combustion engine and a generator device that generates AC power are supported on the frame. The internal combustion engine drives the generator device. An electrically powered starting device is coupled to the internal combustion engine. A control panel is coupled to the frame and includes at least one AC outlet and a battery receptacle that is electrically coupled to the starting device. The battery receptacle is materially the same as a foot of a cordless power tool that receives a battery pack. According to one aspect, the battery pack for the cordless power tool may be permanently mounted in the battery receptacle and provides electrical power to the starting device. The battery receptacle may be contained in an enclosure. The enclosure may provide biasing members urging the battery pack into the battery receptacle.

Abstract: A portable generator system having a generator for generating an electrical output signal, an internal combustion engine for driving the generator, a starter for starting the internal combustion engine, an alternator for generating an AC signal for powering a charger assembly, a battery pack, and a charger subsystem. The charger system has a charger assembly that receives the AC signal and generates a DC charging signal for recharging the battery pack. The charger assembly has a first switch and a second switch. The first switch is used to apply an output of the battery to energize the starter. The second switch, when placed in a Start position, enables current from the battery pack to energize the starter while inhibiting the application of the DC charging signal to the battery pack. When placed in the Charge position, the second switch inhibits the battery pack output from energizing the starter while enabling the DC charging signal to be applied to the battery pack.

Abstract: A portable power driven system has a manually movable frame. In one example, an internal combustion engine and a generator device that generates AC power are supported on the frame. The internal combustion engine drives the generator device. An electrically powered starting device is coupled to the internal combustion engine and is controllable by a remote ignition system to enable the start-up of the internal combustion engine from a remote location. A control panel is coupled to the frame and includes at least one AC outlet and a battery receptacle that is electrically coupled to the starting device. The battery receptacle is materially the same as a foot of a cordless power tool that receives a battery pack.

Abstract: A portable internal combustion engine and a charging device that generates AC power are supported on a manually movable frame. A coupling mechanism which can include a starter circuit and starting device, or a charging circuit and charging device, or both device couples a battery receptacle terminal block to the internal combustion engine. The battery receptacle can include various features to permit and retain electrical coupling between a battery pack for a cordless power tool. For examples key protrusions and corresponding recesses can be associating with latching projections. Additionally or alternatively, cooperating rails and recesses may be associated with the battery pack and receptacle, respectively. Spring loaded movable clips or resilient flexing clips can be included to act on the battery pack. An electrical cord may also be used to couple receptacle terminals to the coupling mechanism.

Abstract: An evaporative emissions fuel system for a general-purpose engine includes a fuel tank with a valve assembly located within the fuel tank for guiding fuel vapor to a canister. The canister contains activated charcoal to treat the fuel vapor and guide the vapor to a carburetor which burns the fuel vapor and hydrocarbons. The valve assembly has a valve opening for receiving the fuel vapor and a float responsive to the fuel within the tank for sealing the valve opening when the fuel within the tank is at a feel level capable of entering the valve opening.

In another aspect, the battery receptacle is disposed in an enclosure supported by the frame. In an aspect, the enclosure further includes a battery charger.

Abstract: A power tool including a motor, an output member and a transmission disposed between the motor and the output member. The transmission includes a ring gear with opposite axial end faces. The power tool also includes a clutch for limiting an output of the transmission. The clutch includes an annular clutch face disposed about the ring gear. At least a portion of a side of the ring gear is configured such that an included angle between the annular clutch face and the at least a portion of the side of the ring gear is about ninety five degrees to about one hundred fifty degrees.

Abstract: A saw blade clamping arrangement for a power tool includes a clamp support, a biasing member and an actuation member. The clamp support is interconnected with the drive shaft for reciprocating motion with the drive shaft relative to a housing of the power tool. The clamp support is configured to selectively receive a saw blade of the power tool in various orientations. A release lever is carried by the housing and is manually rotated to move a control member between a first position in which the saw blade is coupled to the drive shaft and a second position in which the saw blade may be displaced from the drive shaft. In at least one of the orientations, the saw blade is positioned offset from the drive shaft and proximate one of the side walls of the tool housing to allow for flush cutting of a work piece.

Abstract: A reciprocating saw 11 with a keyless blade clamp 35 having a slotted-channel 37 in a clamp body 39 for receiving a blade 40 alternatively in first and second, intersecting cutting planes. The blade 40 may be alternatively oriented in four 90° offset orientations with the blade teeth facing in the same directions as the top, bottom, left and right side of the saw 11. When the retainer 53 is in the clamp disengaged position, a blade 40 may be slidably inserted and removed from the channel 37 in any of the four 90° offset orientations. A retainer 53 is located in a track 51 in the clamp body 39 and is movable between clamp engaged and disengaged positions. When the blade 40 is located in the first cutting plane, the retainer 53 engages the edge 55 of the blade. When the blade 40 is in the second cutting plane, the retainer 53 engages the sidewall 57 of the blade 40.
