Cord-type mowing machine

Claim 2

A cord-type mowing machine comprising a housing fixedly secured to a shaft and defining a rotary head, a coil of nylon cord contained in said housing and having an uncoiled end portion extending from the inside of the coil downwardly through the bottom of the housing at a point spaced apart radially from an axis of the shaft, a bellmouth-like socket mounted on the underside of said housing and having an outer diameter less than that of said housing, a groove formed in said socket along its inner arcuate surface for guiding and deflecting radially outwardly the end portion of said cord to form a radially extending free traveling portion of said cord, and a retainer threadedly engaging the lower end of said shaft for holding said end po1tion of the cord in the groove in said bellmouth-like socket.

Claim 3

A cord-type mowing machine as claimed in claim 1 wherein said retainer has an outer arcuate surface complementary to said inner arcuate surface of said bellmouth-like socket.

Claim 4

A cord-type mowing machine as claimed in claim 1 wherein said bellmouth-like socket is formed integrally with said housing.

Claim 5

A cord-type mowing machine including a drive shaft, a housing means secured to said drive shaft and defining a rotary head, means defining an enclosure in said housing means surrounding said drive shaft for accommodating a coil of cord, said housing means including an undersurface extending substantially perpendicular to said drive shaft and said drive shaft having an end portion projecting below said undersurface, means defining a bellmouth socket extending from said undersurface, said bellmouth socket having an outer edge of a diameter smaller than the outer diameter of said housing means, said bellmouth socket further having a lower surface including an arcuate inner portion extending from said undersurface of said housing means and a substantially radial outer portion extending from said arcuate portion to said outer edge, means defining a cord groove in said lower surface of said socket extending from said outer edge of said socket to said undersurface of said housing means, means defining a cord passage in said housing means adjacent said shaft and connecting a radially inner portion of said enclosure with said cord groove and a detachable retainer means on said projecting end portion of said shaft for holding a cord in said groove.

Claim 6

A cord-type mowing machine including a drive shaft, a housing means secured to said drive shaft and defining a rotary head, means defining an enclosure in said housing means surrounding said drive shaft for accommodating a coil of cord, said housing means including an undersurface extending substantially perpendicular to said drive shaft and said drive shaft having an end portion projecting below said undersurface, means defining a bellmouth socket extending from said undersurface, said bellmouth socket having an outer edge of a diameter smaller than the outer diameter of said housing means, said bellmouth socket further having a lower surface including an arcuate inner portion extending from said undersurface of said housing means and a substantially radial outer portion extending from said arcuate portion to said outer edge, means defining a cord groove in said lower surface of said socket extending from said outer edge of said socket to said undersurface of said housing means, means defining a cord passage in said housing means adjacent said shaft and connecting a radially inner portion of said enclosure with said cord groove and a detachable retainer means on said projecting end portion of said shaft for holding a cord in said groove.

Claim 7

A machine as claimed in claim 4 wherein said housing means comprises an upper portion and a lower portion and said bellmouth socket is formed integrally with said lower portion.

Claim 8

A machine as claimed in claim 4 wherein said retainer means as an upper surface complementary to said lower surface of said socket.

Claim 9

A machine as claimed in claim 4 wherein said retainer means is screw threaded onto said projecting end portion of said shaft.

Claim 10

A machine as claimed in claim 4 wherein said passage extends substantially in parallel to said drive shaft.
