Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
278 words
In a multi-directional positioner for moving one element relative to another element, a. a ball-like member, b. housing having a socket therein receiving said ball-like member with a rotating fit with the inner surface of said socket extending an angular distance around said ball-like member to retain said ball-like member in said socket with a portion of said ball-like member projecting outwardly of said socket, c. means operatively connecting said portion of the ball-like member projecting outwardly of said socket to said one element, d. means operatively connecting said housing to said another element, e. at least one arcuate groove in the inner surface of said housing extending in a plane passing generally through the center of said ball-like member, f. a piston in said arcuate groove in said housing and pivotally connected to the adjacent side of said ball-like member, g. means to introduce fluid under pressure into said arcuate groove in said housing selectively at opposite sides of the piston therein to impart relative movement between said ball-like member and said housing, h. at least one arcuate groove in the outer surface of said ball-like member extending in a plane passing generally through the center of said ball-like member and perpendicular to said arcuate groove in the inner surface of said housing, i. a piston in said arcuate groove in the outer surface of said ball-like member and pivotally connected to the adjacent portion of said housing, and j. means to introduce fluid under pressure into said arcuate groove in the outer surface of said ball-like member selectively at opposite sides of the piston therein to impart relative movement between said ball-like member and said housing.
Claim 2
Dependent Claim
278 words
In a multi-directional positioner for moving one element relative to another element, a. a ball-like member, b. housing having a socket therein receiving said ball-like member with a rotating fit with the inner surface of said socket extending an angular distance around said ball-like member to retain said ball-like member in said socket with a portion of said ball-like member projecting outwardly of said socket, c. means operatively connecting said portion of the ball-like member projecting outwardly of said socket to said one element, d. means operatively connecting said housing to said another element, e. at least one arcuate groove in the inner surface of said housing extending in a plane passing generally through the center of said ball-like member, f. a piston in said arcuate groove in said housing and pivotally connected to the adjacent side of said ball-like member, g. means to introduce fluid under pressure into said arcuate groove in said housing selectively at opposite sides of the piston therein to impart relative movement between said ball-like member and said housing, h. at least one arcuate groove in the outer surface of said ball-like member extending in a plane passing generally through the center of said ball-like member and perpendicular to said arcuate groove in the inner surface of said housing, i. a piston in said arcuate groove in the outer surface of said ball-like member and pivotally connected to the adjacent portion of said housing, and j. means to introduce fluid under pressure into said arcuate groove in the outer surface of said ball-like member selectively at opposite sides of the piston therein to impart relative movement between said ball-like member and said housing.
Claim 3
Dependent Claim
37 words
A multi-directional positioner as defined in claim 1 in which oppositely disposed arcuate grooves are provided in the inner surface of said housing with oppositely disposed pistons therein pivotally connected to opposite sides of said ball-like member.
Claim 4
Dependent Claim
44 words
A multi-directional positioner as defined in claim 1 in which said means to introduce fluid under pressure into said arcuate groove in said housing comprises a fluid supply conduit communicating with said arcuate groove in said housing at each side of said piston therein.
Claim 5
Dependent Claim
55 words
A multi-directional positioner as defined in claim 1 in which said piston in said arcuate groove in the outer surface of said ball-like member is provided with fluid supply passageways therethrough for supplying fluid under pressure selectively at opposite sides of said piston in said arcuate groove in the outer surface of said ball-like member.
Claim 6
Dependent Claim
45 words
A multi-directional positioner as defined in claim 1 in which said piston in said arcuate groove in the outer surface of said ball-like member carries a laterally and outwardly projecting shaft-like member which is mounted for rotation in a bearing recess carried by said housing.
Claim 7
Dependent Claim
42 words
A multi-directional positioner as defined in claim 5 in which said projecting shaft-like member is provided with fluid supply passageways therethrough which communicate with fluid supply passageways through said piston in said arcuate groove in the outer surface of said ball-like member.
Claim 8
Dependent Claim
91 words
A multi-directional positioner as defined in claim 1 in which a pair of said multi-directional positioners are operatively connected to each other by interconnecting said means to introduce fluid under pressure into said arcuate groove in said housing and by interconnecting said means to introduce fluid under pressure into said arcuate groove in the outer surface of said ball-like member so that upon relative movement between said ball-like member and said housing of one positioner imparts a like relative movement between said ball-like member and said housing of the other positioner.
