Abstract
Abstract A knot-tying device for securing a loop in a line or cord between the free end and an intermediate portion of the line comprising a rigid tapered body member having a plurality of apertures, one aperture adjacent the apex of the body and the other substantially in the center of the body. An intermediate portion of the line is looped through the center aperture and secured about each tapered side. The free end of the line is coupled through the apex aperture, thus forming a loop in the line between the free end and the intermediate portion of the line. The divergent body prevents accidental disengagement of the intermediate line portion.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
231 words
A device in combination with a flexible line for securing a loop in one free end of said flexible line, said combination comprising: a body member, said body member having a means for attaching the free end of said flexible line to said body member and said body member having a loop receiving aperture and at least two peripheral surface portions, each peripheral surface portion being disposed on opposite sides of said loop receiving aperture, said two peripheral surface portions being angularly disposed relative to each other such that relative to the means for attaching said line to said body on an axis towards said loop receiving aperture said peripheral side surface portions have an angular relative position which diverges away from when taken with said means for attaching said free end of said line to said body member; and a flexible line having its free end connected to said means for attaching said free end of said line to said body portion and an intermediate segment of said flexible line having a loop portion received through said loop receiving aperture and connected back between said divergent peripheral surface portions such as to be looped about each peripheral surface portion, whereby a loop in said flexible line is secured between said free end connected to said body member and said intermediate line segment connected to said angularly diverging peripheral surface portions.
Claim 2
Independent Claim
231 words
A device in combination with a flexible line for securing a loop in one free end of said flexible line, said combination comprising: a body member, said body member having a means for attaching the free end of said flexible line to said body member and said body member having a loop receiving aperture and at least two peripheral surface portions, each peripheral surface portion being disposed on opposite sides of said loop receiving aperture, said two peripheral surface portions being angularly disposed relative to each other such that relative to the means for attaching said line to said body on an axis towards said loop receiving aperture said peripheral side surface portions have an angular relative position which diverges away from when taken with said means for attaching said free end of said line to said body member; and a flexible line having its free end connected to said means for attaching said free end of said line to said body portion and an intermediate segment of said flexible line having a loop portion received through said loop receiving aperture and connected back between said divergent peripheral surface portions such as to be looped about each peripheral surface portion, whereby a loop in said flexible line is secured between said free end connected to said body member and said intermediate line segment connected to said angularly diverging peripheral surface portions.
Claim 3
Dependent Claim
16 words
