Abstract
A cutting head for a nylon-cord mower and the like, comprising a case housing an inner spool on which it is wound at least a length of nylon cord, elastically loaded by a helical spring, with the two ends of said nylon cord protruding through pairs of annular members mounted on said case in diametrally opposed locations. The inner spool is formed by a cylindrical body with at least two holes aligned along an axis intersecting the axis of the spool, and that can be axially aligned with the two annular members for allowing the replacement of the nylon cord without opening the cutting head.
Claims11
A cutting head for a nylon-cord mower, said cutting head comprising
- a case including a pair of diametrically opposed annular members, said members for allowing each end of an associated nylon cord to protrude therethrough;
- an inner spool disposed within said case, said inner spool comprising a cylindrical body, two peripheral flanges formed on either end of said cylindrical body, and a pair of diametrically opposed apertures formed through the surface of said cylindrical body, said pair of apertures disposed along an inclined axis with respect to a spool axis of rotation and capable of being aligned with the pair of diametrically opposed annular members, wherein when said apertures are aligned with said annular members, a nylon cord may be inserted completely therethrough and thereafter wound onto said inner spool without separating said inner spool from said case.
