Sight mounting for weapons such as crossbows
First Claim
1. A projectile-firing weapon having mounted thereon a sight mounting member, and further comprisinga) an adjustment mechanism whereby said sight mounting member is adjustable in its disposition relative to the weapon;
- b) an indicator comprising a rotationally operable scale and pointer mechanism to provide a read-out indicative of the disposition of said sight mounting member, the indicator being of a size substantially greater than the range of adjustment of said sight mounting member so as to provide a readily legible visual indication of said disposition; and
c) operating means for coupling said indicator to said sight mounting member in such a way as to operate the indicator by movement of the sight mounting member, said operating means comprising a mechanical movement-magnifying mechanism which includes a connecting member coupled to said sight mounting member and moveable relative to said indicator in accordance with the disposition of said sight member, and rack and pinion means connecting said connecting member with said rotationally operable scale and pointer mechanism.

Abstract
A crossbow or other weapon with an adjustable sight mounting member is provided with an indicator mechanism which provides a read-out indicative of the disposition of the sight mounting member, the indicator being of a size substantially greater than the range of adjustment of the sight mounting member so as to provide a readily legible visual indication of said disposition. The indicator comprises a pointer rotatably movable over an arcuate scale and driven by a rack and pinion connection with an operating member which is coupled with the sight mounting member. The sight mounting member is adjustable by means of a screw which is operable independently of the indicator.

9. A sight mounting assembly comprising
a) a base member adapted for mounting on a weapon; -
b) a sight mounting member adjustably carried by said base member and adapted to carry a sighting device for the weapons; c) adjustment means for adjusting the disposition of said sight mounting member relative to said base member through a predetermined range of adjustment; d) indicator means mounted on said sight mounting member and comprising a rotationally operable scale and pointer mechanism to provide a read-out indicative of the disposition of said sight mounting member relative to said base member, the indicator being of a size substantially greater than the range of adjustment of said sight mounting member so as to provide a readily legible visual indication of said disposition; and e) operating means for coupling said indicator to said sight mounting member in such a way as to operate said indicator means by movement of the sight mounting member relative to said base member, said operating means comprising a mechanical movement-magnifying mechanism which includes a connecting member coupled to said sight mounting member and moveable relative to said indicator means in accordance with the disposition of said sight mounting member, and rack and pinion means connecting said connecting member with said rotationally operable scale and pointer mechanism. - View Dependent Claims (10, 11, 12, 13)
