Abstract
Abstract An apparatus for facilitating the securing of the free end of a line to a line attachment. Such attachments might be hook eyes, swivels, lures, fishing leaders, and the like which are commonly used in fishing with hook and line. The apparatus employs a rotating arm which wraps the free end of a line around the source line without twisting the source line to facilitate the tying of a clinch knot and other similar knots. The instrument has incorporated in or attachable to its structure; a line cutter, attachment holding means, a novel hook eye threader, and a light.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
247 words
A portable apparatus for wrapping a free end of a line about a source line for the purpose of forming a knot and comprising; (a) a base having a top and bottom surface and the bottom surface is detachably securable to a stable surface by a securement means, (b) an attachment holding member projecting upward from the top surface of the base and having as a part thereof at least one attachment holding means, (c) a shaft support member projecting upward from the top surface of the base and spaced apart from the attachment holding member, (d) a shaft having an axial bore directed towards the attachment holding member and rotatably mounted in the shaft support member and the shaft has a winding arm projecting radial from and mounted to the shaft at a location near the end of the shaft and positioned between the attachment holding member and the shaft support member and a turning knob is secured to the shaft, and the shaft, the knob, and the arm define a longitudinal slot which communicates from the axial bore of the shaft to the outside of the shaft, knob, and arm so that when the slot is aligned with a mating slot in the shaft support a line may be passed through the slots into the axial bore of the shaft, and (e) a line holding means attached to the winding arm at a location near the end of the arm most distant from the shaft.
Claim 2
Dependent Claim
247 words
A portable apparatus for wrapping a free end of a line about a source line for the purpose of forming a knot and comprising; (a) a base having a top and bottom surface and the bottom surface is detachably securable to a stable surface by a securement means, (b) an attachment holding member projecting upward from the top surface of the base and having as a part thereof at least one attachment holding means, (c) a shaft support member projecting upward from the top surface of the base and spaced apart from the attachment holding member, (d) a shaft having an axial bore directed towards the attachment holding member and rotatably mounted in the shaft support member and the shaft has a winding arm projecting radial from and mounted to the shaft at a location near the end of the shaft and positioned between the attachment holding member and the shaft support member and a turning knob is secured to the shaft, and the shaft, the knob, and the arm define a longitudinal slot which communicates from the axial bore of the shaft to the outside of the shaft, knob, and arm so that when the slot is aligned with a mating slot in the shaft support a line may be passed through the slots into the axial bore of the shaft, and (e) a line holding means attached to the winding arm at a location near the end of the arm most distant from the shaft.
Claim 3
Dependent Claim
25 words
The apparatus of claim 1 wherein the line holding means is a slotted flat piece of resilient, puncturable, and cutable material secured to the arm.
Claim 4
Dependent Claim
24 words
The apparatus of claim 1 wherein an attachment holding means is a small diameter rod projecting from the top of the attachment holding member.
Claim 5
Dependent Claim
24 words
The apparatus of claim 1 wherein an attachment holding means is a flat piece of resilient, puncturable, cutable material secured to the holding member.
Claim 6
Dependent Claim
22 words
The apparatus of claim 1 wherein an attachment holding means is a cylinder of resilient, puncturable material recessed into the holding member.
Claim 7
Dependent Claim
63 words
The apparatus of claim 1 wherein the apparatus is provided with a line cutter comprising an edged cutting member overlaid with a slotted line guide which aligns with a mating slotted line guide in the body of the holding member so that when a line is drawn into the slotted line guide the line is guided against the edged member and severed thereby.
Claim 8
Dependent Claim
65 words
The apparatus of claim 1 wherein the shaft support member has incorporated into its structure a hooded light comprising a battery in series with a light bulb in series with an on off switch which makes and breaks a circuit to initiate and terminate the flow of electricity in the circuit and a hood which directs light from the bulb towards the attachment holding member.
Claim 9
Dependent Claim
69 words
The apparatus of claim 1 wherein the shaft is proviced with at least one guide disk, the guide disk defining a central cylindrical bore which is coaxial with the bore of the shaft and having adjacent thereto a portion of the guide disk forming a resilient detent through which a line may be passed into and taken out from the cylindrical bore by means of resiliently deforming the detents.
Claim 10
Dependent Claim
183 words
An eye threading guide which is attachable and detachable from the arm of a knot tying apparatus comprising a one piece body having a top surface parallel to a bottom surface and a side surface perpendicular to the top and bottom surface and the body defines a short small diameter cylindrical bore perpendicular to and between the top and bottom surfaces and the bore communicates with a top conical line guide bore which is largest at its intersection with top surface and which intersects the cylindrical bore near the vertex of the conical bore and a bottom conical eye guide bore which is largest at its intersection with the bottom surface and which intersects the cylindrical bore near its vertex and the eye guide bore is bisected along diametrically opposed elements of the conical bore to permit access for a hook eye to the tapered sides of the eye guide bore and the body of the threading guide further defines an entry slot which communicates between the outside of the body and the common axis of the conical guides and the cylindrical bore.
Claim 11
Dependent Claim
183 words
An eye threading guide which is attachable and detachable from the arm of a knot tying apparatus comprising a one piece body having a top surface parallel to a bottom surface and a side surface perpendicular to the top and bottom surface and the body defines a short small diameter cylindrical bore perpendicular to and between the top and bottom surfaces and the bore communicates with a top conical line guide bore which is largest at its intersection with top surface and which intersects the cylindrical bore near the vertex of the conical bore and a bottom conical eye guide bore which is largest at its intersection with the bottom surface and which intersects the cylindrical bore near its vertex and the eye guide bore is bisected along diametrically opposed elements of the conical bore to permit access for a hook eye to the tapered sides of the eye guide bore and the body of the threading guide further defines an entry slot which communicates between the outside of the body and the common axis of the conical guides and the cylindrical bore.
Claim 12
Dependent Claim
27 words
The threading guide of claim 9 wherein the bottom eye guide bore is provided with circumferential grooves to serve as indices for hook eyes of various diameters.
