ABSTRACT:
A bump-actuable filament feed for vegetation trimmers; when the cutting length of filament breaks or wears short, the user without interrupting cutting simply bumps the cutting head on the ground deploying a fresh cutting-length of filament. Bumping causes a spring-restored spool latch to yield an increment of spool rotation, feeding a corresponding increment of filament from the spool. For replenishing the filament supply when exhausted, the spool snaps out in one embodiment on pressing a button, and a fresh spool as easily snaps into place.
For applications in which bumping the cutting head against the ground is not desired an analogous operation is provided by adaptation of the basic structure.
