Abstract
Abstract A line tying device especially useful for tying a fish line to a fish hook or to another fish line. The line is helically wound a number of times around a mandrel body; the free end of the line is then passed through a groove in the mandrel body into the space circumscribed by the helical windings. A depression in the tip end area of the mandrel body keeps the helical winding in place; after the windings have been formed a pulling force may be exerted on the free end of the line to draw the wound area (knot) off of the mandrel body.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
131 words
A line tying device comprising an elongated mandrel body having a first palm-engageable section formed with curved side surfaces, a second thumb-engageable section extending axially from the first section, and a convergent nose section extending axially from the thumb-engageable section, a longitudinal groove in the nose section, said groove having a bottom surface that angles acutely from the undersurface of the nose section to the upper face of the thumb-engageable section, and a relatively wide shallow transverse depression in the upper face of the nose section, whereby the tail end of a line can be angled downwardly through the longitudinal groove, then wrapped a number of times around the nose section and associated depression, and then extended through the longitudinal groove into the space within the wrapped sections of the line.
Claim 2
Dependent Claim
131 words
A line tying device comprising an elongated mandrel body having a first palm-engageable section formed with curved side surfaces, a second thumb-engageable section extending axially from the first section, and a convergent nose section extending axially from the thumb-engageable section, a longitudinal groove in the nose section, said groove having a bottom surface that angles acutely from the undersurface of the nose section to the upper face of the thumb-engageable section, and a relatively wide shallow transverse depression in the upper face of the nose section, whereby the tail end of a line can be angled downwardly through the longitudinal groove, then wrapped a number of times around the nose section and associated depression, and then extended through the longitudinal groove into the space within the wrapped sections of the line.
Claim 3
Dependent Claim
17 words
The line tying device of claim 1 wherein the upper face of said thumb-engageable section is flat.
Claim 4
Dependent Claim
36 words
The line tying device of claim 2 wherein the flat upper face of the thumb-engageable section has a plural number of closely-spaced transverse grooves adapted to facilitate frictional retention of a line on the flat face.
Claim 5
Dependent Claim
29 words
The line tying device of claim 1 wherein the bottom surface of the longitudinal groove is angled to the upper face of the thumb-engageable section at about seventeen degrees.
Claim 6
Dependent Claim
27 words
The line tying device of claim 1 wherein the transverse depression extends to a depth that is about one half the transverse thickness of the nose section.
Claim 7
Dependent Claim
34 words
The line tying device of claim 1 wherein the bottom surface of the longitudinal groove terminates at a point on the nose section undersurface that is within the general plane of the transverse depression.
Claim 8
Dependent Claim
15 words
The line tying device of claim 1 wherein the palm-engageable section has a circular cross-section.
Claim 9
Dependent Claim
29 words
The line tying device of claim 1 wherein the transverse depression has an arcuate concave bottom surface that merges smoothly into the surface contour on the convergent nose section.
Claim 10
Dependent Claim
25 words
The line tying device of claim 1 wherein the bottom surface of the longitudinal groove has a length that is several times the groove depth.
Claim 11
Dependent Claim
47 words
The line tying device of claim 1 and further comprising a fish hook-engagement ring structure carried on the elongated body remote from the convergent nose section, whereby a fish hook can be positioned alongside the elongated body for connection to a fishline prior to a line-tying operation.
Claim 12
Dependent Claim
47 words
The line tying device of claim 10 wherein the ring structure is swingably connected to the elongated body for movement to a position lying against said body, such that the shank area of the fish hook can extend parallel to the longitudinal axis of the elongated body.
Claim 13
Independent Claim
130 words
A device for tying a line to an eye of a fish hook, comprising an elongated mandrel body having a first palm-engageable section defining the body axis, a second thumb-engageable section extending axially from the first section, and a convergent nose section extending axially from the thumb-engageable section, a longitudinal groove in the nose section, said groove having a bottom surface extending at an acute angle to the body axis, and a shallow transverse depression in the upper face of the convergent nose section, said depression being wide enough to accommodate several wrap-around sections of a line during a tying operation, said thumb-engageable section having a flat upper face, said flat upper face having at least one transverse groove therein adapted to accommodate therein the eye of a fish hook.
Claim 14
Independent Claim
130 words
A device for tying a line to an eye of a fish hook, comprising an elongated mandrel body having a first palm-engageable section defining the body axis, a second thumb-engageable section extending axially from the first section, and a convergent nose section extending axially from the thumb-engageable section, a longitudinal groove in the nose section, said groove having a bottom surface extending at an acute angle to the body axis, and a shallow transverse depression in the upper face of the convergent nose section, said depression being wide enough to accommodate several wrap-around sections of a line during a tying operation, said thumb-engageable section having a flat upper face, said flat upper face having at least one transverse groove therein adapted to accommodate therein the eye of a fish hook.
Claim 15
Dependent Claim
46 words
The device of claim 12 wherein the longitudinal groove has a width sufficient to receive therein the shank area of a fish hook and a line, whereby the line can simultaneously be wrapped around the shank area of the fish hook and the convergent nose section.
Claim 16
Dependent Claim
63 words
The device of claim 13 wherein the longitudinal groove has a depth sufficient to receive the tail end of a line after the line has been wrapped around the convergent nose section, whereby the tail end of the line can be pulled to draw the wrapped section of the line off the convergent nose section onto the shank area of the fish hook.
