Abstract
Apparatus is provided for cutting vegetation with a flexible non-metallic string-like member in the manner of a flail. A circular body with one or more peripheral apertures is concentrically mounted on the shaft of an electric motor for rotation in a cutting plane, and a section of non-metallic line is interconnected with the circular body member and passed through the peripheral aperture to form the flail. The line may be press-fitted into one or more grooves which may further communicate with apertures or windows in the rim of the circular body. Alternatively, the line may be either a single section of line, or it may be two separate sections of line.
Claims17
Apparatus for cutting vegetation and the like comprising
- driving means having a rotatable shaft extending therefrom perpendicularly to a cutting plane,
- a head member fixedly mounted on said shaft and having a recess located therein to provide an opening extending inwardly from one side thereof and said head member further having at least one peripheral aperture providing in part a passageway communicating with said recess and said passageway residing within said head member,
- at least one non-metallic flexible line member slidably received in close confinement within the passageway and extending from said recess radially outwardly and at least partially across said head member and through said peripheral aperture into said cutting plane, and
- means on said head member for securing said line member against slidable movement from said aperture into the cutting plane but permitting selective withdrawal of said line member from said aperture.
An apparatus for cutting vegetation and the like, comprising:
- a. a head arranged for rotation within a circular periphery and about an axis generally perpendicular with a cutting plane;
- b. said head member having a recess provided thereinto and at least one aperture at a location spaced from the axis and adjacent the circular periphery, and said aperture forming at least in part a passageway within said head member for receiving a line member in close confinement while extending outwardly from said recess through said head member to said aperture;
- c. at least one non-metallic flexible line member extending from said recess across said head member and through said aperture into the cutting plane;
- and
- d. securing means integral with said head member for holding said line member against slidable movement radially outwardly from said aperture during rotation of said head member.
