Abstract
The cutting head assembly of a motor-driven flexible line trimmer (10) has a line feed mechanism which includes a housing member connected to and driven by a drive shaft (28) from the prime mover and having a centrally located cylindrical wall (46) for receiving a compression spring (30). A locking plate and cup member (14) is reciprocably disposed around the cylindrical wall and compresses the spring substantially to its normal running position where it is held in position relative to the housing member by suitable retention structure. A spool (16) is disposed around the cup portion of the locking plate and cup member and unless restrained, is free to rotate relative to the housing member to pay out line through an aperture in the housing member. A cover ring member (18) has a central opening which is coupled to the housing member and holds a ground engaging button member (20) against the lower end of the cup member when both are in the lower, normal running position, yet permits the button member to reciprocate upwardly against the locking plate and cup member to compress the spring when the button member is bumped against the ground. The locking plate and cup member is driven by the housing member while being permitted to reciprocate axially, while the button member is driven by the cover ring member by way of the housing member while also permitting the button member to reciprocate axially. The spool is held against axial reciprocation by the cover member and the housing member in a manner permitting rotation of the spool relative to the housing. The upper and lower faces of the spool have radially extending ribs (84, 88) which cooperate with locking teeth (86) on the lower face of the locking plate and escapement teeth (90) on the upper edge of the button member to lock the spool against rotation when the locking plate and cup member are in the lower, normal running position, and to permit the spool to rotate through a controlled increment when the button is bumped against the ground and thus reciprocated, along with the locking plate member, upwardly then downwardly as a result of the biasing force of the spring.
