Anti-vibration resilient supports

Claim 1

A RESILIENT SUPPORT COMPRISING A FIXED FIRST RIGID ARMATURE HAVING FLANGE MEANS FOR SECUREMENT TO A SUPPORTING SURFACE, A MOVEABLE SECOND RIGID ARMATURE HAVING FLANGE MEANS FOR SECUREMENT TO A SUPPORTED OBJECT, A MOVEABLE THIRD RIGID ARMATURE AND AT LEAST ONE BLOCK OF ELASTOMER INTERPOSED BETWEEN SAID FIRST AND THIRD ARMATURES AND BETWEEN SAID SECOND AND THIRD ARMATURES AND ADHERENT TO SAID ARMATURES, SAID THIRD ARMATURE AND SAID ELASTOMER BLOCK CONSTITUTING, TOGETHER, THE ONLY CONNECTION BETWEEN SAID TWO FIRST MENTIONED ARMATURES, WHEREIN, (A) SAID FIXED FIRST RIGID ARMATURE HAS A VERTICAL AXIS OF SYMMETRY, THE SECTIONS OF SAID FIRST ARMATURE TAKEN IN PLANES PERPENDICULAR TO SAID AXIS CONSISTING OF CLOSED CURVES SYMMETRICAL ABOUT SAID AXIS, THE VERTICAL SECTIONS OF SAID FIRST ARMATURE TAKEN IN PLANES PASSING THROUGH SAID AXIS CONSISTING OF PAIRS OF SUBSTANTIALLY STRAIGHT LINES OBLIQUE TO SAID AXIS, AND SYMMETRICAL WITH RESPECT TO EACH OTHER AND WITH RESPECT TO SAID AXIS, (B) SAID MOVABLE SECOND RIGID ARMATURE IS DISPOSED IN OPPOSED SPACED RELATION TO SAID FIRST ARMATURE AND HAS AN AXIS OF SYMMETRY NORMALLY IN COINCIDENCE WITH SAID FIRST MENTIONED AXIS OF SYMMETRY, THE SECTIONS OF SAID SECOND ARMATURE TAKEN IN PLANES PERPENDICULAR TO SAID SECOND MENTIONED AXIS OF SYMMETRY CONSISTING OF CLOSED CURVES SYMMETRICAL ABOUT SAID SECOND MENTIONED AXIS, THE VERTICAL SECTIONS OF SAID SECOND MENTIONED ARMATURE TAKEN IN PLANES PASSING THROUGH SAID SECOND AXIS CONSISTING OF PAIRS OF SUBSTANTIALLY STRAIGHT LINES OBLIQUE TO SAID SECOND AXIS AND SYMMETRICAL WITH RESPECT TO EACH OTHER AND WITH RESPECT TO SAID SECOND AXIS, THE OBLIQUITY OF THE LINES OF THE SAID SECOND ARMATURE IN THE VERTICAL SECTIONS BEING OPPOSED TO THOSE OF THE LINES IN THE SAID FIRST ARMATURE VERTICAL SECTIONS, (C) SAID MOVABLE THIRD RIGID ARMATURE NORMALLY IS DISPOSED IN OPPOSED SPACED RELATION TO BOTH SAID FIRST AND SECOND ARMATURES ABOUT SAID VERTICAL AXIS AND IS SYMMETRICAL THEREABOUT, EVERY SECTION OF SAID THIRD ARMATURE TAKEN IN A PLANE PASSING THROUGH ITS AXIS CONSISTING OF TWO PAIRS OF SUBSTANTIALLY STRAIGHT LINES, THE LINES OF ONE PAIR MAKING AN ANGLE WITH EACH OTHER SUBSTANTIALLY EQUAL TO THAT ANGLE MADE WITH THE TWO LINES IN THE VERTICAL SECTION OF SAID FIRST ARMATURE LOCATED IN THE SAME AXIAL PLANE, THE LINES OF THE OTHER PAIR MAKING AN ANGLE WITH EACH OTHER SUBSTANTIALLY EQUAL TO THAT ANGLE MADE BY TWO LINES IN VERTICAL SECTION OF SAID SECOND ARMATURE LOCATED IN THE SAME AXIAL PLANE, (D) SAID ELASTOMER BLOCK IS ARRANGED SO THAT THE SIDE WALL OF SAID THIRD ARMATURE LOCATED OPPOSITE SAID FIRST ARMATURE IS NORMALLY SUBSTANTIALLY PARALLEL THERETO AND THE SIDE WALL OF SAID THIRD ARMATURE LOCATED OPPOSITE SAID SECOND ARMATURE IS NORMALLY SUNSTANTIALLY PARALLEL THERETO, (E) MOST OF THE HORIZONTAL SECTIONS OF SAID ELASTOMER BLOCK INTERSECT EITHER BOTH SAID FIRST AND SAID THIRD ARMATURES OF BOTH SAID SECOND AND SAID THIRD ARMATURES,AND (F) THE LENGTH OF SAID VERTICAL SECTION LINES OF EACH PORTION OF SAID ELASTOMER BLOCK LOCATED BETWEEN SAID THIRD ARMATURE AND EACH OF SAID FIRST AND SECOND ARMATURES TAKEN IN THE DIRECTION OF THE SAID ARMATURE LINES TAKEN IN THE VERTICAL PLANES IS SEVERAL TIMES THE THICKNESS OF SAID ELASTOMER BLOCK MEASURED TRANSVERSELY TO SAID LINES.
