Multi-Directional Positioner
US Patent:
4129844, Dec 12, 1978
Filed:
Jul 14, 1977
Appl. No.:
5/815519
Inventors:
William M. Wells - Midfield AL
International Classification:
H01F 718
US Classification:
335268
Abstract:
A multi-directional positioner for moving one element relative to another element wherein a socket in a housing receives a ball with a rotating fit with a portion of the ball projecting outwardly of the socket and being connected to one element and the housing being connected to the other element. An arcuate groove in the socket extends in a plane passing generally through the center of the ball and receives an electrically actuated power unit which is pivotally connected to the side of the ball. An arcuate groove in the outer surface of the ball extends in a plane passing generally through the center of the ball and perpendicular to the groove in the socket and receives an electrically actuated power unit which is pivotally connected to the adjacent portion of the housing. The power units are energized singularly and/or jointly to impart relative movement between the ball and the housing.

International Classification:
F01C 900, F15B 700
US Classification:
60325
Abstract:
A multi-directional positioner for moving one element relative to another element wherein a socket in a housing receives a ball with a rotating fit with a portion of the ball projecting outwardly of the socket and being connected to one element and the housing being connected to the other element. An arcuate groove in the socket extends in a plane passing generally through the center of the ball and receives a piston which is pivotally connected to the adjacent side of the ball. An arcuate groove in the outer surface of the ball extends in a plane passing generally through the center of the ball and perpendicular to the groove in the socket and receives a piston which is pivotally connected to the adjacent portion of the housing. Fluid is introduced under pressure selectively into the arcuate grooves in the ball and the arcuate groove in the socket to impart relative movement between the ball and the housing.
