IPC: A01D34/90
Filed: 1980-06-25
Abstract: A narrow profile power handle uniquely adapted for use as a flexible line trimmer having improved handling and safety features is disclosed. The power handle is also equipped with a quick connect and disconnect coupling and is useful for driving attachments to produce hand held rotary implements and tools such as brush cutters, edgers, cultivators, drills, etc., hand held reciprocating implements and tools such as hedge clippers, saws, etc., as well as portable water pumps, air compressors, generators, etc. The crankshaft of a two-stroke internal combustion engine is disposed along the longitudinal axis of a narrow profile housing which includes a rear handle having a hand grip portion disposed above and projecting rearwardly parallel to the axis of the housing. The cylinder extends upwardly from the crankcase, the carburetor is disposed below the crankcase, the flywheel, ignition system and starter to the rear, and the gas tank is disposed below the rear handle. The muffler is disposed along the forward face of the housing for discharging products of combustion forwardly of the housing and away from the operator, thereby permitting the assembly to be rotated for various trimming operations without exposing the operator to the risk of burn injury. A recoil starter handle, a choke control, throttle control and ignition kill switch are conveniently clustered around and near the hand grip portion of the rear handle which allows the operator to observe and exercise positive control over both the power handle and the cutter head while starting and operating the engine. The power handle includes a quick disconnect coupling for attaching the portable power unit to drive various attachments. As a result of this arrangement, the power handle is generally symmetrical about the longitudinal vertical plane and is of minimum width. The drive shaft of the line trimmer assembly is aligned with the crankshaft of the engine and a forward handle is disposed above the drive shaft ahead of the engine housing. As a result, the center of gravity of the overall line trimmer assembly is below and between the forward and rearward handles, thereby providing improved balance and maneuverability.
