摘要： An improved guard is provided for flexible cutting element devices such as lawn trimmers. The guard extends above the cutting planed formed by the circular travel of the flexible cutting element. The flexible cutting element is allowed to extend past the perimeter of the guard, such that the cutting action created by the travel of the cutting element occurs immediately past the edge of the guard. A cutter may be provided outside of the perimeter of the guard and extending into the plane formed by the rotation of the cutting element to function as a cutter for setting the length of a cutting element being used. The guard may be formed as a single piece or as a composite which when assembled encircles the center assembly of the cutting device.

摘要： A portable, operator-carried power tool having an implement supported on an operator-carried frame, and a lightweight, four-stroke, internal combustion engine drivably connected to the implement and supported by the frame. The engine has a crankshaft situated in a crankshaft housing and a cylinder block secured to the crankshaft housing, the crankshaft being provided with a crankcase ventilation passage extending between the crankcase and an outlet end in communication with an air/fuel induction passage. A passage establishes communication between the interior of the crankcase and the valve chamber through a cam and cam gear region of the cylinder block. An oil mist generator is connected drivably to the crankshaft for agitating liquid oil in the crankcase to establish a lubricating oil mist. The crankcase, the cam region and the valve chamber form a closed oil mist containment whereby lubricating oil mist is distributed throughout the engine during operation regardless of angular orientation of the engine. The crankshaft ventilation passage establishes lean crankcase gas distribution to the engine air/fuel intake. The crankcase is designed to avoid flow of liquid oil through the crankshaft passage when the engine is not running. meet the 2000 CARB emissions regulations. In addition, they operate quieter compared to two-stroke engines. Unlike two-stroke engines which simultaneously admit a fresh charge of fuel and air mixed with lubrication oil while exhausting combustion products, including unburned fuel, a four-stroke internal combustion engine maintains the lubricating oil relatively isolated from the combustion chamber. The intake and exhaust valve region and the camshaft and cam drive portions of a four-stroke internal combustion engine are lubricated with oil supplied from the crankcase. The combustion chamber remains relatively isolated from the crankcase. Lubricating oil is not introduced into the air/fuel mixture as in the case of a two-stroke engine. Lubrication of the cylinder wall occurs as a film of crankcase oil develops on the cylinder wall. The piston rings seal the variable volume combustion chamber and effectively prevent mixing of the lubrication oil with the combustion gases. One disadvantage of using four-stroke internal combustion engines for outdoor power tools, aside from a weight disadvantage, traditionally has been the inability to operate the engine upside down or at the extreme tilt angles that would be required by the operator. Oil in the crankcase in those instances would tend to be drained through the engine block to the intake and exhaust valve region of the engine and would enter the air/fuel mixture intake flow path as well, thereby upsetting otherwise efficient fuel combustion during operation. Continuous operation of the engine, even for relatively short periods, may result in piston seizure because of an interruption of lubrication oil flow to the cylinder wall. Many of the shortcomings associated with the use of four-stroke engines with outdoor power tools have been solved by the teachings of U.S. Pat. Nos. 5,241,932 and 5,421,292, which are incorporated in the present disclosure by reference. Those patents, which are assigned to the assignee of the present invention, disclose engines which avoid the weight disadvantage of using a four-stroke internal combustion engine in an outdoor power tool. Further, they make provision for efficient engine operation throughout a wide range of angular dispositions or orientations. Copending U.S. patent application Ser. No. 08/614,835, filed Mar. 8, 1996, which also is assigned to the assignee of the present invention, describes a further improvement in the earlier prior art teachings. That improvement makes it possible to maintain distribution of lubrication oil mist throughout the engine while maintaining the liquid lubrication oil isolated from the valve chamber and the cam and cam drive system. The engine of the copending application, which is incorporated in the present disclosure by reference, includes a lubricating oil mist passage that is formed in the crankshaft and in the crankshaft counterweight. The crankshaft passage facilitates distribution of lubricating oil in the form of an oil mist through the region of the camshaft and the camshaft drive of the engine and through oil mist flow passages to an overhead valve chamber. A lubricating oil mist generator driven by the crankshaft agitates liquid oil in the crankshaft and develops a lubricating oil mist which is transferred through the engine in a flow path defined in part by the crankshaft passage. Large oil droplets in the oil mist and liquid oil in the crankcase are prevented from entering the crankshaft passage by the effect of centrifugal force due to the rotation of the crankshaft and the crankshaft counterweight during engine operation. A fine oil mist, however, may pass through the crankshaft passage and through the engine lubrication system since the mist is relatively unaffected by the centrifugal forces created by the rotating crankshaft.

摘要： A motorized vegetation trimmer apparatus comprising an elongate main handle to which is connected a motor that rotatably drives a trimmer head located at a distal end of the handle. The trimmer head carries one or more radially outwardly projecting cutting members which cut vegetation as the trimmer head rotates. Each cutting member comprises a finite length of flexible strand. The cutting member is releasably gripped by a one-way gripping mechanism including a reciprocating gripping member and a device for biasing the gripping member into gripping contact with the strand.

摘要： A powered trimmer unit has been developed for single arm/hand use and without the need to bend over during use. The powered trimmer unit for grass and brush in attached to both a persons upper arm and forearm whereby the trimmer unit becomes an extension of the operator's arm and can readily be manipulated by one arm. This powered unit relieves the level of fatigue in the use of powered trimmer units since it does not require the use of two arms and a bending over during use.

摘要： A portable trimmer capable of applying to a throttle valve a different operation from that according to a throttle operation lever. The portable trimmer includes a brake device for braking the movement of a cutting blade that is released in conjunction with a throttle operation. The portable trimmer includes a throttle wire having a first throttle wire extending between a throttle operation lever and a swingable member, and a second wire portion extending between a swingable member and a throttle to provide a first operation transmission path for transmitting the movement of the throttle operation lever to the throttle valve. The portable trimmer further includes an additional operation lever for performing a different operation from said throttle operation, and a pulley pivotally attached to the swingable member. The second wire portion extends between the throttle and the additional operation lever through the pulley to provide a second operation transmission path independent of the first operation transmission path.
