Shock and vibration isolating mountings for aircraft engines and the like

Claim 1

A MOUNTING DEVICE FOR ISOLATING VIBRATION AND SHOCK BETWEEN TWO BODIES SUCH AS AN AIRCRAFT ENGINE AND AN AIRFRAME COMPRISING AN INNER MEMBER ADAPTED TO BE SECURED TO ONE OF SAID BODIES AND AN OUTER MEMBER ADAPTED TO BE SECURED TO THE OTHER OF SAID BODIES, SAID INNER MEMBER HAVING A CYLINDRICAL OUTER SURFACE AND SAID OUTER MEMBER HAVING A CYLINDRICAL INNER SURFACE, A PLURALITY OF CYLINDRICAL CUSHIONS WITH THE LONGITUDINAL AXES THEREOF EXTENDING RADIALLY OUTWARDLY FROM SAID INNER MEMBER, THE INNER END OF EACH OF SAID CYLINDRICAL CUSHIONS BEARING AGAINST THE CYLINDRICAL OUTER SURFACE OF SAID INNER MEMBER, MEANS FOR HOLDING THE OUTER ENDS OF SAID CYLINDRICAL CUSHIONS IN UNIFORMLY SPACED RELATION CIRCUMFERENTIALLY OF THE INNER SURFACE OF SAID OUTER MEMBER, A PAIR OF HOLLOW CYLINDRICAL CUSHIONS HAVING THEIR LONGITUDINAL AXES EXTENDING PARALLEL WITH THE AXIS OF THE CYLINDRICAL OUTER SURFACE OF SAID INNER MEMBER, EACH OF SAID HOLLOW CYLINDRICAL CUSHIONS HAVING FORMED ON THE INNER END THEREOF A PLURALITY OF NOTCHES ADAPTED TO RECEIVE AND SNUGLY SURROUND ONE-HALF OF THE DIAMETER OF EACH OF SAID RADIALLY DISPOSED CYLINDRICAL CUSHIONS AND THE INNER ENDS OF SAID HOLLOW CYLINDRICAL CUSHIONS BEING IN ENGAGEMENT WITH EACH OTHER IN THE SPACES BETWEEN SAID CYLINDRICAL CUSHIONS AND IN A PLANE SUBSTANTIALLY COINCIDENT WITH THE LONGITUDINAL AXES OF SAID CYLINDRICAL CUSHIONS, AND MEANS SECURED TO SAID INNER MEMBER FOR HOLDING SAID HOLLOW CYLINDRICAL CUSHIONS BY ENGAGEMENT WITH THE OUTER ENDS THEREOF, WHEREBY LOADS TENDING TO CAUSE RELATIVE MOVEMENT BETWEEN SAID INNER MEMBER AND SAID OUTER MEMBER IN DIRECTIONS AXIALLY OF THE CYLINDRICAL SURFACES THEREOF WILL CAUSE AXIAL COMPRESSION OF SAID HOLLOW CYLINDRICAL CUSHIONS AND LOADS TENDING TO CAUSE RELATIVE MOVEMENT BETWEEN SAID INNER MEMBER AND SAID OUTER MEMBER IN DIRECTIONS RADIALLY OF THE CYLINDRICAL SURFACES THEREOF WILL CAUSE AXIAL COMPRESSION OF SAID CYLINDRICAL CUSHIONS, EACH OF SAID CUSHIONS CONSISTING OF A COMPRESSED MASS OF SPRINGY METAL WIRE IN WHICH A SUBSTANTIAL AMOUNT OF THE WIRE CONSISTS OF TRANSVERSELY CRIMPED INDIVIDUAL LENGTHS OF WIRE EXTENDING GENERALLY PARALLEL WITH EACH OTHER AND WITH THE CYLINDRICAL AXIS OF THE CUSHION.
