Patent number: 9516807Abstract: A trimmer head for use with either clockwise or counterclockwise trimmer heads, including the use of a bidirectionally dispensing spool. Various locations of passages straight through the trimmer head and spool are shown along with various locations of components of the ratcheting mechanism to allow for winding of the trimmer line on the trimmer head and for limiting the amount of line dispensed during “bumping” of the trimmer head knob on the ground. Because of the careful arrangement of the components, the trimmer head can have line wound in a single direction on the spool and still dispense line regardless of the direction that the trimmer head rotates by speeding up or slowing down the spool relative to the trimmer head housing to allow line to dispense independent of the direction of the rotation of the trimmer machine drive shaft rotating the trimmer head.Type: GrantFiled: November 20, 2014Date of Patent: December 13, 2016Inventor: George E. Alliss

Patent number: 9474205Abstract: In a rotating grass trimmer, a top loading line blade and corresponding head securely hold the cutting lines with multiple orientations of the line blade. An alternative embodiment provides a simplified loading scheme where a cutting line is loaded into the trimmer head from its outside, through a line outlet to a fixed receiver without the need for a moving or mechanical line gripping or biting type mechanism. With this construction, a worn line can be replaced by pulling it back out or by reversing it back through the same outlet from which it was initially inserted. The design eliminates practically all of the costs associated with the current state of the art rapid loading mechanisms as there is no physical compression, gripping or biting into the line by any mechanical or moving mechanism. Additionally, the line is insertable in multiple orientations.Type: GrantFiled: October 28, 2009Date of Patent: October 25, 2016Assignee: AERO-FLEX TECHNOLOGIES, INC.Inventor: Vincent D. Morabit

Patent number: 9380743Abstract: A trimmer head assembly and the method of configuring the trimmer head assembly. The trimmer head assembly has a housing that attaches to a string trimmer machine. A spool is provided inside the housing. The spool rotates about an axis of rotation. The spool can move longitudinally along the axis of rotation between a first position and a second position. A ratcheting mechanism is provided between the trimmer head housing and the spool. When the spool is in its first position, the ratcheting mechanism enables the spool to continuously rotate about the axis of rotation in the direction opposite that in which the trimmer head assembly spins. The ratchet mechanism also prevents the spool from rotating within the housing in the same direction in which the trimmer head is spinning.Type: GrantFiled: May 20, 2014Date of Patent: July 5, 2016Assignee: Torvian, Inc.Inventor: George Alliss
