Abstract:

A converging lines of sight mount which utilizes handgun type scopes. It provides for elevation, windage and draw length adjustments. It features a graduated range scale with highly discernable graduations each representing less than one yard. It is constructed for mounting on a bow forward of the archer, having two forward facing oscillating arms with integral gears. A linkage connects both arms at one end and a pinion imparts synchronized motion at the opposite end. Said arms arc lengths, being dissimilar, impart a tilting motion to the linkage. Said tilting provides for converging lines of sight at the archer's eye at any elevation setting. Said converging point equates to draw length and is adjustable by means of an offset rotary device which alters the arm length ratio between arms. An effective windage adjustment provides in excess of 240 inches at 100 yards with a resolution of approximately 2 inches.
