Mechanical servosystem for optical aiming device
First Claim
1. In an armored vehicle turret having a weapon system mounted externally so as to be movable in elevation about an axis extending across the rear of the turret, a mechanical servosystem to maintain an optical aiming device having an optical axis in alignment with the weapon comprising:
- (a) a motion input mechanism located on the turret near the axis of movement of the weapon, the input mechanism comprising;
(i) an input pulley rotatably mounted on the turret, the input pulley having an input shaft;
(ii) means connecting the input shaft to the weapon system comprising a deforming parallelogram linkage including a first link rod attached to the input shaft and a second link rod connected to the first link rod and the weapon system; and
,(iii) means connecting a first end of the flexible motion transmission device to the input pulley;
(b) a motion output mechanism;
(c) first means interconnecting the motion input means to the weapon system such that elevational motion of the weapon about its axis is imparted to the motion input mechanism;
(d) a flexible motion transmission device interconnecting the motion input mechanism to the motion output mechanism; and
,(e) second means interconnecting the motion output mechanism to the optical aiming device such that elevational motion of the weapon is transmitted from the motion input mechanism, through the flexible motion transmission device, to the motion output mechanism to maintain the optical axis in alignment with the weapons elevational position.

Abstract
A mechanical servosystem for connecting the pivoting weapon support to an tical aiming device such that the optical sighting axis remain in alignment with the elevation of the weapon is described. A motion input mechanism is connected to the pivoting weapons mounting. The optical device is connected to a mechanical motion output mechanism which, in turn, is connected to the motion input mechanism via a flexible motion transmission device. A linkage interconnects the weapon mounting with the motion input mechanism such that any elevational movement of the weapon is automatically transferred to the optical aiming device to maintain the alignment of the optical axis with the weapon.
