ABSTRACT:
An adjustable archery bow sight for attachment to an archery bow to facilitate archery accuracy. The adjustable archery bow sight includes a base, a carriage which is slidably mounted to the base and a mechanism connected to the base to attach the adjustable archery bow sight to the bow. A sight pin assembly is mounted to the carriage. One of the carriage and the base has a planar surface. A drive roll is mounted to the other of the base and the carriage. The drive roll has an outer circumferential surface which engages the planar surface. One of these two surfaces is knurled and non-conformable and the other of these two surfaces is softer than the knurled surface and conformable in a complementary driving manner to the knurled surface. Rotation of the drive roll about an axis of rotation causes the carriage to slide relative to the base. The adjustable archery bow sight is further provided with a rotating mechanism for rotating the drive roll. In one embodiment, the drive roll is mounted to the base and the circumferential surface of the drive roll is knurled and non-conformable. The planar surface is softer than the circumferential surface and conformable. A mechanism is also provided for controlling the force between the two surfaces and the resistance of the drive roll to being turned.
