ABSTRACT:
A spring actuated differential mechanism for controlling the angular position of one or more vanes which is particularly suitable for use in a guidance system for a guided weapon. A pair of vanes are mounted on an axle and a bevel differential is mounted centrally between them. The pivots of one set of bevels is normal to and solid with the vane axle and meshing therewith is a second set of bevels coaxial with but free on the vane axle. Each bevel of the second set of bevels is connected to one of a pair of large pinion gears which are induced to turn in opposite directions by an associated coil spring. Each of these pinion meshes with a small pinion, rotation of which is governed by a low power solenoid controlled escapement. Momentary energization of one solenoid permits a desired rotation of the associated escapement and a correspondingly smaller rotation of the associated large pinion and bevel. Because the other large pinion and its associated bevel are locked by their associated escapement, the meshing bevels of the first set rotate around the stationary bevels by an amount equal to one half of the rotation of the large pinion, thus inclining the vanes and their associated axle. Energization of the other solenoid effects a similar movement of the vanes but in the opposite direction. Two sets of vanes at right angles in the same axial plane can also be controlled by vesting two differential mechanisms, from each of which one gear has been eliminated, at right angles one within the other.
