Abstract
Abstract A torsionally loaded treble hook is disclosed characterized by the fact that the torsion is provided by a torsion member in the form of a wire which is disposed adjacent to and substantially parallel to the shanks of the hooks. The shank of the hooks and the major portion of the torsional member are enclosed in a sleeve in a closely packed configuration so that the width of the shank portion of the treble hook is minimized. The trigger mechanism disclosed is a pivotable and collapsible weed guard. A method of making the novel treble hook is also disclosed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
140 words
A hook device for catching fish comprising: a stationary hook having a shank portion and a curved portion; at least one oscillatable hook having a shank portion and a curved portion disposed adjacent to the stationary hook; a slender torsion bar disposed parallel and adjacent to the shank portions of the stationary hook and the oscillatable hook, said slender bar being secured to the curved portion of the oscillatable hook in a preloaded condition; a sleeve surrounding at least a portion of the slender torsion bar and the shank portions of the stationary hook and the oscillatable hook, said sleeve having an interior cross sectional area that provides a minimum clearance fit around the slender torsion bar and the shank portions of the stationary hook and the oscillatable hook whereby the cross sectional area of the hook device is minimized.
Claim 2
Dependent Claim
140 words
A hook device for catching fish comprising: a stationary hook having a shank portion and a curved portion; at least one oscillatable hook having a shank portion and a curved portion disposed adjacent to the stationary hook; a slender torsion bar disposed parallel and adjacent to the shank portions of the stationary hook and the oscillatable hook, said slender bar being secured to the curved portion of the oscillatable hook in a preloaded condition; a sleeve surrounding at least a portion of the slender torsion bar and the shank portions of the stationary hook and the oscillatable hook, said sleeve having an interior cross sectional area that provides a minimum clearance fit around the slender torsion bar and the shank portions of the stationary hook and the oscillatable hook whereby the cross sectional area of the hook device is minimized.
Claim 3
Dependent Claim
18 words
The device of claim 1 having two oscillatable hooks each having a shank portion and a curved portion.
Claim 4
Dependent Claim
64 words
The device of claim 2 wherein said slender torsion bar comprises two substantially straight portions disposed adjacent and parallel to the shank portion of the oscillatable hooks, and said slender torsion bar having an end portion adjacent to each straight portion, and each one of said end portions being secured to one of the curved portions of the oscillatable hooks, in a preloaded condition.
Claim 5
Dependent Claim
15 words
The device of claim 1 wherein said means for providing a bearing surface comprises solder.
Claim 6
Dependent Claim
50 words
The apparatus of claim 1 wherein said means for maintaining comprises: a coiled hinge attached to the upper shank portion of the stationary hook; and a pivotable weed guard coupled to the coiled hinge and freely pivotable on said hinge and adapted to secure the hooks in a closed position.
Claim 7
Dependent Claim
56 words
The apparatus of claim 5 wherein said week guard comprises an elongated wire terminating in a bent end portion with a constriction thereon whereby the ends of the hooks are maintained in a closed position by the bent end portion, and the week guard is frictionally secured to the ends of the hooks by the constriction.
