Abstract
Abstract Apparatus is provided, particularly for a gyroscope mounting, for supporting a first body on a second body so that relative movement between the two bodies is permitted in three mutually perpendicular directions only, i.e., relative rotary movement is prevented. Damping means may be connected between the bodies to provide a shock and vibration isolating arrangement.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
202 words
An apparatus for supporting a first body on a second body so that relative movement between the two bodies is permitted in three mutually perpendicular directions only, comprising I. a first parallel motion linkage comprising A. at least two substantially rigid parallel members each connected at one end with the first body so as to be pivotable about respective spaced apart axes, II. a second parallel motion linkage comprising A. at least two substantially rigid parallel members each connected at one end with the second body so as to be pivotable about respective spaced apart axes, III. all said axes being parallel to one another, and IV. a third parallel motion linkage comprising A. a pair of substantially rigid parallel members each connected with the other ends of all the members of the first and second parallel motion linkages so that at each connection between a member of said third linkage and a member of said first or second linkage, relative pivotal movement is possible i. about one axis parallel to said first and second linkage axes and ii. about another axis perpendicular to said one axis and parallel to planes containing said first linkage axes and said second linkage axes respectively.
Claim 2
Independent Claim
202 words
An apparatus for supporting a first body on a second body so that relative movement between the two bodies is permitted in three mutually perpendicular directions only, comprising I. a first parallel motion linkage comprising A. at least two substantially rigid parallel members each connected at one end with the first body so as to be pivotable about respective spaced apart axes, II. a second parallel motion linkage comprising A. at least two substantially rigid parallel members each connected at one end with the second body so as to be pivotable about respective spaced apart axes, III. all said axes being parallel to one another, and IV. a third parallel motion linkage comprising A. a pair of substantially rigid parallel members each connected with the other ends of all the members of the first and second parallel motion linkages so that at each connection between a member of said third linkage and a member of said first or second linkage, relative pivotal movement is possible i. about one axis parallel to said first and second linkage axes and ii. about another axis perpendicular to said one axis and parallel to planes containing said first linkage axes and said second linkage axes respectively.
Claim 3
Dependent Claim
55 words
An apparatus according to claim 1, in which the first and second parallel motion linkages comprise plate members, half the number of said plate members each having an aperture and the other half the number of said plate members each passing through one of the apertures so that the plate members are arranged in X-configurations.
Claim 4
Dependent Claim
31 words
An apparatus according to claim 2, in which the third parallel motion linkage comprises plate members of substantially less mass and thickness than the members of the first and second linkages.
Claim 5
Dependent Claim
65 words
An apparatus according to claim 1, in which the connections between the third parallel motion linkage and the first and second parallel motion linkages are formed by bearings capable of allowing movement about two perpendicular axes and the connections between the first and second parallel linkages and the first and second bodies are formed by bearings capable of allowing movement about at least one axis.
Claim 6
Dependent Claim
16 words
An apparatus according to claim 4, in which all the connections are formed by spherical bearings.
Claim 7
Dependent Claim
24 words
An apparatus according to claim 1, in which damping means are connected between the two bodies to provide a shock and vibration isolating arrangement.
Claim 8
Dependent Claim
25 words
An apparatus according to claim 6, in which the damping means comprises a two layer spring steel hoop having damping material sandwiched between the layers.
