Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
132 words
In combination with a compound bow having eccentric wheels rotatably mounted thereon, a cable passing around the wheels, said wheels each turning approximately 180° between the rest position and full draw, a device for visually comparing the rotational rates of said eccentric wheels, a bowstring, said device comprising: a support; a pair of movable indicators mounted on said support and positioned adjacent the nocking point of the bowstring where they can readily be seen by the archer as he draws the bowstring, said support being engageable by the bowstring and movable rewardly thereby; and means actuated by rotation of said eccentric wheels for driving the movable indicators so that a user may visually compare the relative rates of rotation of the indicators and the corresponding eccentric wheels with respect to one another.
Claim 2
Dependent Claim
132 words
In combination with a compound bow having eccentric wheels rotatably mounted thereon, a cable passing around the wheels, said wheels each turning approximately 180° between the rest position and full draw, a device for visually comparing the rotational rates of said eccentric wheels, a bowstring, said device comprising: a support; a pair of movable indicators mounted on said support and positioned adjacent the nocking point of the bowstring where they can readily be seen by the archer as he draws the bowstring, said support being engageable by the bowstring and movable rewardly thereby; and means actuated by rotation of said eccentric wheels for driving the movable indicators so that a user may visually compare the relative rates of rotation of the indicators and the corresponding eccentric wheels with respect to one another.
Claim 3
Dependent Claim
54 words
The device of claim 1, wherein said movable indicators are mounted closely adjacent one another, one of said indicators being driven by the rotation of the eccentric wheel at the upper end of the bow, and the other indicator being driven by rotation of the eccentric wheel at the lower end of the bow.
Claim 4
Dependent Claim
37 words
The device of claim 2, wherein said indicators comprise a pair of indicator wheels rotatably mounted on said support, said indicator wheels having graduation markings provided thereon so that any relative rotation between them can be observed.
Claim 5
Dependent Claim
76 words
The device of claim 3, wherein each of said indicator wheels has a pulley fixed thereto, and said means for driving the indicator wheels comprises a pair of cords, each of said cords being trained around one of said pulleys, and each cord having one end attached to the bowstring adjacent the corresponding eccentric wheel, and resilient means attached to the other ends of said cords for taking up the cords as the eccentric wheels turn.
Claim 6
Dependent Claim
77 words
The device of claim 4, wherein said support comprises a long slender shaft with means at one end thereof to receive the bowstrings, a bracket fixed to said shaft upon which said indicator wheels are rotatably supported; and said resilient means comprises elastic members attached to the other ends of said cords for taking up the cords as the eccentric wheels turn, said elastic members being attached to a fitting at the front end of said shaft.
Claim 7
Dependent Claim
45 words
The device of claim 3, wherein said support comprises a long slender shaft substantially identical to an arrow shaft, with means at one end thereof to receive the bowstring, and a bracket fixed to said shaft; said indicator wheels being rotatably supported on said bracket.
Claim 8
Dependent Claim
52 words
The device of claim 1, wherein said means for driving said movable indicators comprises a pair of cords, each having one end attached to the bowstring adjacent the corresponding eccentric wheel, and resilient means attached to the other ends of said cords for taking up the cords as the eccentric wheels turn.
