Cord line mower

Claim 1

A cord line mower which comprises: (a) a support housing having a hollow open chamber extending downwardly therefrom; (b) a plurality of wheels mounted to said housing to enable movement of said housing over a ground surface at a controlled height thereabove in a preferred direction; (c) a spool assembly within said housing; (d) a flexible non metallic cord line cutting element wound repeatedly within said spool assembly, said cutting element having two free unsupported lengths, each extending generally radially outward from an opposite side of said spool assembly during driven rotation thereof, the free unsupported lengths during cutting operations, define a plane substantially perpendicular to axis of rotation of said spool assembly to which the cutting element is wound thereto; (e) a drive assembly for rotatably driving the spool assembly at a speed sufficient to extend and stiffen the lengthens of said cutting element to permit impact cutting of uncut grass particles thereby; (f) a handle bar for manipulating said cord line mower; and (g) means for lifting said spool assembly into said drive assembly for extending the unsupported lengths of said cutting element thus releasing extra lengths of said cutting element, wherein said spool assembly includes: (a) a cord line housing having a pair of opposite side holes therein; (b) a spool within said cord line housing for holding said cutting element; and (c) a hollow shaft having an external bevel edge therearound, said shaft extends upwardly from said cord line housing; wherein said drive assembly includes: (a) a casing mounted into said support housing; (b) a motor mounted on said support housing, said motor having a vertical shaft extending downwardly into said casing; (c) a first pulley wheel connected to the vertical shaft in said casing; (d) a second pulley wheel rotatably mounted in said casing around said hollow shaft of said spool assembly; and (e) an endless belt placed around said first and second pulley wheels driven by said motor, wherein said lifting means includes: (a) a plurality of rollers mounted to the top surface of said support housing; (b) a plurality of eyelets mounted along said handle bar; (c) a lever assembly mounted to upper portion of said handle bar; (d) a spool lifter mounted to the underside of said cord line housing; (e) an elongated cable affixed at one end to said spool lifter and extends upwardly through said hollow shaft over said rollers and through said eyelets with other end affixed to said lower assembly; (f) said second pulley wheel having a cone shaped hole with a spring biased clutch mechanism therein so that when said lever assembly is manually activated said spool lifter will raise said cord line housing in which said bevel edge will engage with said clutch mechanism; and (g) at least one cutter mounted within the hollow open chamber of said support housing to chop off the excess of the unsupported lengths of the cutting element.
