Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
105 words
In a bow sight, the combination of, an upper near sight opening formed generally in the outline of an upwardly turned greater arc having ends, a lower sight portion opening formed generally in the outline of a pair of non-parallel arms connected at their bottom ends and having their top ends upwardly turned, said lower sight being adjustably mounted with said arms being slidably connected to said ends of said greater arc so that said lower sight can be adjusted toward said greater arc, thus increasing the angle between said arms, and adjusted away from said greater arc, thus decreasing the angle between said arms.
Claim 2
Dependent Claim
105 words
In a bow sight, the combination of, an upper near sight opening formed generally in the outline of an upwardly turned greater arc having ends, a lower sight portion opening formed generally in the outline of a pair of non-parallel arms connected at their bottom ends and having their top ends upwardly turned, said lower sight being adjustably mounted with said arms being slidably connected to said ends of said greater arc so that said lower sight can be adjusted toward said greater arc, thus increasing the angle between said arms, and adjusted away from said greater arc, thus decreasing the angle between said arms.
Claim 3
Dependent Claim
74 words
The invention as set forth in claim 1 wherein said ends of said arc terminate in loops defining eyes, an upper lateral support arm depends outwardly from one of said loop eyes, said arms of said lower sight portion are adjustably mounted in said eyes, and one of said arms has a lateral support arm extending therefrom on the same side of said sight as said upper lateral support arm and generally parallel thereto.
Claim 4
Dependent Claim
70 words
The invention as set forth in claim 2 wherein said arc portion, said loops and said upper lateral arm are formed by twisting two strands of wire together, and said lower sight lateral arm is formed by twisting two strands of wire together, the wires being separated at the junction of said lateral arm with said inner intersecting arm into two separate single wires which form said lower sight portion.
Claim 5
Dependent Claim
38 words
The invention as set forth in claim 1, including means for adjustably mounting said sight on a bow to accomodate and secure adjustment of said lower sight arms in sighting relationship with respect to said greater arc ends.
