Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
168 words
Apparatus for cutting vegetation and the like by means of a flexible cutting filament rotatably operable within a cutting plane, said apparatus comprising a rotatable head structure operable about an axis generally perpendicular to said cutting plane, means for rotating said head structure, a spool rotatable with said head structure and also rotatably shiftable in respect thereto, said spool and head structure also being relatively axially shiftable, said spool being arranged to carry a supply of filament and emit a predetermined increment thereof upon relative rotation between said spool and said head structure, and means for controlling said relative rotation by the relative axial shifting of said spool and head structure, said control means comprising two sets of interengageable detents, one set comprising two axially spaced rows of detents and the other set comprising a row of detents selectively engageable with either of said first named rows, one set of detents being provided upon a pair of independently fabricated members cooperatively associated with said spool for rotation therewith.
Claim 2
Dependent Claim
168 words
Apparatus for cutting vegetation and the like by means of a flexible cutting filament rotatably operable within a cutting plane, said apparatus comprising a rotatable head structure operable about an axis generally perpendicular to said cutting plane, means for rotating said head structure, a spool rotatable with said head structure and also rotatably shiftable in respect thereto, said spool and head structure also being relatively axially shiftable, said spool being arranged to carry a supply of filament and emit a predetermined increment thereof upon relative rotation between said spool and said head structure, and means for controlling said relative rotation by the relative axial shifting of said spool and head structure, said control means comprising two sets of interengageable detents, one set comprising two axially spaced rows of detents and the other set comprising a row of detents selectively engageable with either of said first named rows, one set of detents being provided upon a pair of independently fabricated members cooperatively associated with said spool for rotation therewith.
Claim 3
Dependent Claim
30 words
Apparatus as set forth in claim 1 wherein said members are secured to but separable from said spool, and threaded fastener means is provided for securing said members in position.
Claim 4
Dependent Claim
161 words
Apparatus for cutting vegetation and the like by means of a flexible cutting filament rotatably operable within a cutting plane, said apparatus comprising a rotatable head structure operable about an axis generally perpendicular to said cutting plane, means for rotating said head structure, a spool rotatable with said head structure and also rotatably shiftable in respect thereto, said spool and head structure also being relatively axially shiftable, said spool being arranged to carry a supply of filament and emit a predetermined increment thereof upon relative rotation between said spool and said head structure, and means for controlling said relative rotation by the relative axial shifting of said spool and head structure, said control means comprising two sets of interengageable detents, one set comprising two axially spaced rows of detents and the other set comprising a row of detents selectively engageable with either of said first named rows, one set of detents comprising a plate member having said detents circumferentially formed thereon.
Claim 5
Dependent Claim
161 words
Apparatus for cutting vegetation and the like by means of a flexible cutting filament rotatably operable within a cutting plane, said apparatus comprising a rotatable head structure operable about an axis generally perpendicular to said cutting plane, means for rotating said head structure, a spool rotatable with said head structure and also rotatably shiftable in respect thereto, said spool and head structure also being relatively axially shiftable, said spool being arranged to carry a supply of filament and emit a predetermined increment thereof upon relative rotation between said spool and said head structure, and means for controlling said relative rotation by the relative axial shifting of said spool and head structure, said control means comprising two sets of interengageable detents, one set comprising two axially spaced rows of detents and the other set comprising a row of detents selectively engageable with either of said first named rows, one set of detents comprising a plate member having said detents circumferentially formed thereon.
Claim 6
Dependent Claim
27 words
Apparatus as set forth in claim 3 wherein said one set of detents comprises a pair of independently fabricated plate members having said detents circumferentially formed thereon.
