Abstract
Abstract A single operating lever control device for selectively operating two trim tabs for a motor boat individually or simultaneously in the same or opposite directions. The operating lever is provided with an inverted semi-spherical bowl movable in a semi-spherical housing. The inner end of the lever is pivoted in a socket bearing at the sphere center point. The bowl edge is provided with bearings for the ends of piston rods of pneumatic cylinders connected with trim tab operating means. The bowl is prevented from rotating but may be pivoted in any direction, thereby permitting free choice of correlation between the piston rod movements and thus the trim tab settings.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
109 words
An assembly for selectively imparting linear movement to two movable members (47, 49) individually or simultaneously in the same or opposite directions, comprising a part-spherical member (19) a member (17) carried by and extending radially inwardly from said part-spherical member (19) a central pivot (13) disposed at the center of curvature of said part-spherical member and receiving the inner end of said radially extending member (17) for universal pivotal movement of said radially extending memBer with said part-spherical member, a casing (25) in which said part-spherical member (19) is universally movable, and means (57, 59 or 73, 70) connecting said part-spherical member with said two movable members (47, 49).
Claim 2
Dependent Claim
109 words
An assembly for selectively imparting linear movement to two movable members (47, 49) individually or simultaneously in the same or opposite directions, comprising a part-spherical member (19) a member (17) carried by and extending radially inwardly from said part-spherical member (19) a central pivot (13) disposed at the center of curvature of said part-spherical member and receiving the inner end of said radially extending member (17) for universal pivotal movement of said radially extending memBer with said part-spherical member, a casing (25) in which said part-spherical member (19) is universally movable, and means (57, 59 or 73, 70) connecting said part-spherical member with said two movable members (47, 49).
Claim 3
Dependent Claim
35 words
An assembly as claimed in claim 1, said casing (25) being part-spherical and of the same curvature as said part-spherical member (19), said part-spherical member being slidably disposed on the inside of said casing (25).
Claim 4
Dependent Claim
44 words
An assembly as claimed in claim 1, the ends (51, 53) of said movable members (47, 49) being pivotally secured to said part-spherical member (19), and means (39, 41) mounting said movable members (47, 49) for limited pivotal movement relative to said casing (25).
Claim 5
Dependent Claim
59 words
An assembly as claimed in claim 1, and an intermediate member (73) disposed between said part-spherical member (19) and said movable members (47, 49), said intermediate member (73) being pivotally mounted at a fixed point (75) located on an imaginary line that passes through said central pivot (13) and that is equidistant from said two movable members (47, 49).
Claim 6
Dependent Claim
24 words
An assembly as claimed in claim 1, and means (63, 67) preventing rotation of said part-spherical member (19) about said radially extending member (17).
Claim 7
Dependent Claim
43 words
An assembly as claimed in claim 5, said means preventing rotation of said part-spherical member (19) comprising a member (63) carried by said part-spherical member (19) and riding in a slot (65) in a member (67) which is fast with said casing (25).
Claim 8
Dependent Claim
31 words
An assembly as claimed in claim 6, said slotted member (67) being part-circular and having a center of curvature that coincides with the center of curvature of said part-spherical member (19).
Claim 9
Dependent Claim
54 words
An assembly as claimed in claim 6, said part-spherical member (19) being connected with said two movable members (47, 49) at locations (57, 59) that are located approximately 45* in opposite directions from the line of intersection that passes through said central pivot (13) and said member (63) that rides in said slot (65).
Claim 10
Dependent Claim
45 words
An assembly as claimed in claim 6, said central pivot (13) and said member (63) that rides in said slot (65) and the connecting means (57, 59) between said part-spherical member (19) and said two movable members (47, 49) being disposed in a common plane.
Claim 11
Dependent Claim
26 words
An assembly as claimed in claim 1, said radially extending member (17) extending radially outwardly of said part-spherical member (19) for manual actuation of said assembly.
Claim 12
Dependent Claim
33 words
An assembly as claimed in claim 10, said radially extending member (17) being screw-threadedly received in said part-spherical member (19) to adjust the frictional engagement between said part-spherical member and said casing (25).
