    摘要: A riveted structure includes a rivet opening (28;128;228;328;428) including a frustoconical surface (32a;132a;232a;332a) intermediate the inboard and outboard surfaces of a plate and a generally cylindrical surface (34a;534a;634a) outboard of the frustoconical surface and terminating at the outboard surface of the plate, the cylindrical surface having a substantially larger diameter than that of the frustoconical surface, and a rivet (14) having a shank (38) deformed into the opening completely to fill the same and achieve a rivet head profile of substantially reduced height.

    摘要: A brush cutting blade (10) has a curved slitter type/non-raker type primary cutting tooth (16), and a preceding appendage (18) forming a combination depth gauge and small stem slitter. The primary tooth (16) terminates over the blade body, with the cutting edge (22) provided by that curved portion of the tooth between its most lateral point (24) and the point (28) of termination over the blade body. The cutting edge (22) is curved but outwardly directed in a slitter configuration throughout its length. The lateral point of the cutting edge determines the kerf width to prevent binding. The slitter cutting edge (40) of the appendage (18) is hook shaped to cut small willowy-­type stems and the appendage has an upper inclined guide edge (38) that guides larger rigid-type stems to the primary cutting tooth (16). The uppermost point (36) of this guide edge of the appendage provides a depth gauge for the primary cutting tooth.

    摘要: A cutting link (18) having a cutter portion (36), a depth gauge portion (38), and a guide edge (48;148) extending between the depth gauge peak (40;140) and cutter portion for guiding a file (52) to sharpen the cutting edge (24) of the cutter portion. In the process of sharpening the cutting edge, the cutter portion is abraded away along a line (46) that extends the guide edge and thereby continues the guiding of the file to properly file the cutting edge.

    摘要: A saw chain length including articulated alternating centre drive links (14) and side links. Cutting links (16,22) provide certain of the side links and a safety side link (20,24) precedes each cutting link. The safety side link and its opposing tie strap link have shaved heel portions (42) and thereby are raised off the guide bar when normally tensioned around the guide bar. The safety link (20,24) is configured whereby engagement thereof by material being cut during a cutting operation induces pivoting of the safety link against the opposing tension force, which tension force thereby absorbs the impact prior to engagement of the heel portion with the guide bar edge.

    摘要: Embodiments of clutches for electric tools, and related methods, are disclosed herein. An electric tool may include an electric motor (106), a drive shaft (110) coupled between the electric motor and a cutting instrument (114), and a clutch (108) coupled between the electric motor and the drive shaft. The clutch may include a motor portion (302) having an exterior surface (316), a drive shaft portion (202) having an exterior surface (224) and forming a mated assembly when mated with the motor portion, and a spring (402) around the motor and drive shaft portions. The spring may exert a holding force on the mated assembly, such that rotation of the motor portion in a first direction loosens the spring and reduces the friction holding force until a torque between the motor and drive shaft portions exceeds the holding force, causing rotation of the motor portion to be decoupled from rotation of the drive shaft portion.
