Abstract: A dispenser for cutting line or string is provided. The dispenser for flexible cutting line includes a generally rectangular housing configured to accept a spool of cutting line, the housing being formed from two mateable side portions configured to snap together, wherein at least one portion of the housing is formed as a first opening to expose a view of an amount of cutting line on the spool; a donut portion disposed centrally in the housing configured for rotatably supporting the spool of cutting line in the housing; and at least one second opening formed in the housing configured for dispensing of the cutting line from the housing.

Abstract: A three-in-one cutting head for a rotary trimmer usable with discrete lengths of string, flail blades, and fan blades is provided. The present disclosure represents an improvement over presently existing multi-purpose trimmer heads in that there is no requirement for the trimmer head to be disassembled in order to change the different blades or strings. The cutting head being selectively rotationally driven through a drive shaft includes a generally cylindrical body having first and second pairs of diametrically opposed apertures disposed on a periphery of the body; at least one clamping member disposed in the body adjacent to each aperture of the first diametrically opposed pair configured for releasably retaining at least one cutting string; and at least one holding member disposed in the body adjacent to each aperture of the second diametrically opposed pair configured for releasably retaining at least one blade.

Abstract: A cutting head for a rotary trimmer is provided. The cutting head of the present disclosure provides a control mechanism for loading a spool member of the cutting head quickly and efficiently without having to disassemble the cutting head. In one embodiment, a control mechanism is provided in the cutting head interacting between a follower member and a spool member so as to provide for one way rotational loading of flails, e.g., cutting line, into the cutting head; in other words, to load the flails, the spool member is rotated continuously 360° in one direction only, e.g., clockwise. In another embodiment, a cutting head allows the flails to be loaded by a ratcheting-type operation, i.e., a back and forth rotational movement, which is less fatiguing and even more efficient in its loading operation.

Abstract: An improved feedout mechanism for the cutting head of a rotary trimmer includes curved surfaces on the top of the lower row of the cam tangs which replace the original flat surfaces of the lower row of cam tangs in the prior art cutting head. Also, the lower surface of each follower tang also has a curved surface which is changed from the original flat design in the prior art. The curved surfaces of the follower tangs and the cam tangs facilitate the line advancement operation and prevents the follower tangs from being hung up with the cam tangs.

Abstract: A cutting head for a string trimmer is provided which accommodates any string gauge thickness and may be easily and quickly re-threaded upon failure of a string previously disposed therein. The cutting head has spring-biased clamping members which are each mounted within a rotatable clamp housing within the head, such that, as a string encounters a solid object, the clamping member and its associated housing are rotated about a generally vertical axis so as to obviate or minimize the development of a stress concentration in the string in the vicinity at which it is engaged by the clamp housing.

Abstract: A rotary head for dethatching machine includes a plurality of channels which are evenly distributed along the outer periphery of the rotary head for receiving flexible dethatching filaments. The dethatching filaments are elongated with a plurality of barb-like protrusions on one end thereof for engagement in the channels of the housings. Once a filament is inserted into a channel, it cannot be pulled out due to the protrusions engaging the interior and exterior walls of the channel of the rotary head. A plurality of rotary heads are mounted on a shaft of a machine. During rotation of the shaft and the rotary heads, the flexible filaments contact the accumulated dethatch with sufficient force to dislodge thatch for later retrieval and clean up.

Abstract: A cutting head for a rotary trimmer has a rotating body from which several flexible cord-like filament cutting blades or flails extend radially so that additional flail length can be fed from the device by merely bumping the rotating body on the ground. The improvement includes a plurality of truncated, bell-shaped configured tangs which extend into a serpentinous cam slot. Bumping of the device on the ground causes the tangs to move from stable positions to other stable positions allowing relative movement between the outer case of the trimmer and a spool of flail therein so that a predetermined length of flail is fed out through the case.
