Sighting device for archery bows
| Details |
Inventors: Kalmbach, Philip;
Assignee:
Primary Examiner: Stearns; Richard R.
Assistant Examiner:
Attorney, Agent or Firm: Peterson, Palmatier, Sturm & Sjoquist, Ltd.
The device includes an elongated body in the form of a metal strip that is secured to one side of an archery bow. At the rear end of the body there is a laterally extending arm on which is mounted a rotatable disc having a number of sight openings therein, the sight openings being at differing distances from the disc's axis of rotation. Detent means assures that whatever sight opening is selected remains in position, yet readily permits another sight opening to be selected for a different shooting range. At the front end of the elongated body is another laterally extending arm, this arm having a plurality of vertically oriented threaded apertures into any one of which can be threaded a pin provided with a bead or ball on its upper end. By properly selecting the particular sighting opening at the rear and by properly adjusting the height of the bead or ball at the front, the bowman is able to control quite accurately the course of the arrow. |

DETAILED DESCRIPTION I claim: 1.
A sighting device for archery bows comprising an elongated body adapted to be attached intermediate its ends to one side of a bow, first and second arms extending laterally from the opposite ends of said body, first sighting means carried on said first arm including a member having a sight opening therein, and second sighting means carried on said second arm including a sighting pin, said member constituting a disc mounted on said first arm for rotation about an axis provided by said first arm.
2.
A sighting device in accordance with claim 1 in which said disc has additional sight openings angularly spaced from said first sight opening and located at different distances from said axis.
3.
A sighting device in accordance with claim 2 including detent means for resisting rotation of said disc to maintain any given sight opening in its selected position.
4.
A sighting device in accordance with claim 3 in which said detent means includes a pin mounted on and projecting from said first arm, said disc having a number of holes angularly oriented with respect to said sight openings for receiving said pin therein to maintain any given sight opening in its selected position.
5.
A sighting device in accordance with claim 4 including a shaft projecting from one side of said disc, said first arm having a hole for rotatably journaling said shaft therein to provide said axis about which said disc can be adjustably rotated.
6.
A sighting device in accordance with claim 5 including a coil spring encircling said shaft, said shaft having a threaded shank, and a wing nut threaded onto said threaded shank for compressing said spring to vary the force with which said disc is pulled to cause engagement of said detent pin in one of said detent holes.
7.
A sighting device in accordance with claim 2 in which said second sighting means includes an upstanding pin.
8.
A sighting device in accordance with claim 7 in which said pin includes a threaded shank and a ball at the upper end thereof, said second arm having a tapped aperture for threadedly engaging said shank so that said ball can be adjusted vertically
