Dispenser For Maintaining Length Of Flexible Line Extending From A Spool
US Patent:
6779274, Aug 24, 2004
Filed:
Aug 14, 2001
Appl. No.:
09/929415
Inventors:
Dennis R. Peterson - Austin TX
Joseph A. Peterson - Austin TX

International Classification:
A01D 34416
US Classification:
30347, 30276
Abstract:
The spool impeller is a fully automatic cutting head for whirling filament vegetation trimmers, simpler, less expensive, and more reliable than the predecessors. Unlike the predecessors, the spool impeller does not waste filament. It consists of a single part, a small diameter spool attached to the drive shaft. The free end of filament coiled on the spool extends tangentially so that the tip traces a circle about the axis of rotation. In use, the coiled filament gradually unwinds to compensate for filament wear, maintaining a cutting swath of precisely constant size. There is no need for the operator to monitor the filament. Feeding new filament is controlled by the aerodynamic drag and centrifugal force acting directly on the extended filament. If the length of the extended filament is correct, drag and centrifugal force balance, and no unwinding or rewinding occurs. Too long, drag dominates over centrifugal force, rewinding the extended filament onto the spool just enough to restore the proper length.
Device For Flexible Line Vegetation Trimmers And Other Applications
US Patent:
6272756, Aug 14, 2001

International Classification:
A01D 3490
US Classification:
30347
Abstract:
A cutting head for a rotary flail retains a coil portion of a cutting line on a spool, and feeds a portion of an excess of the cutting line to the spool to adjust the coil portion and thereby restore a length of the distal portion of the cutting line to maintain a cutting circle of desired size. The distal portion of the cutting line is extended by locating the coil portion such that a centrifugal force arising from rotation of the distal portion overcomes a drag force on the coil portion to unwind a precise amount of the coil portion from the spool. A magazine stores the excess of the cutting line, disposed in a helical path defining a helix having an axis which generally coincides with the axis of the spool. The cutting head has no moving parts, high storage capacity and multiple independent automatic line capability.
