US3770232A — Shock and vibration isolation mount

Claim 1

Independent Claim 273 words

A shock and vibration isolating mount comprising: elongated rod means; a first plurality of disked, disc-shaped annular metal springs attached to peripherally engage each other along alternating inside and outside edges around the rod means; an elastomeric shock and vibration damping annulus disposed around the rod means in fixed connection therewith and in longitudinal spaced connection to one end of the stacked metal springs; a sleeve translatably disposed around the first rod means with one end in engaging relation to the other end of the first metal spring stack; means for fixedly attaching the elastomeric annulus to a supporting structure; means for fixedly connecting the sleeve to a component to be isolated from shock; and a second plurality of disked, disc-shaped annular metal springs stacked to peripherally engage each other along alternate inside and outside edges around the rod means wherein one end of the second spring stack is in longitudinally spaced connection to the other end of the sleeve with the other end of the second spring stack restrained against expansion by the rod means such that rapid acceleration of the supporting structure in one linear direction operates to first compress that portion of the elastomeric annulus disposed intermediate the attaching means and the first spring stack and then to compress the first spring stack while rapid acceleration of the supporting structure in the opposing linear direction operates to first compress that portion of the elastomeric annulus disposed in shock attenuating series with the second spring stack and then to compress the second spring stack thereby attenuating shock and vibration to the connecting means caused by rapid accelerations of the supporting strucuture.

Claim 2

Dependent Claim 273 words

A shock and vibration isolating mount comprising: elongated rod means; a first plurality of disked, disc-shaped annular metal springs attached to peripherally engage each other along alternating inside and outside edges around the rod means; an elastomeric shock and vibration damping annulus disposed around the rod means in fixed connection therewith and in longitudinal spaced connection to one end of the stacked metal springs; a sleeve translatably disposed around the first rod means with one end in engaging relation to the other end of the first metal spring stack; means for fixedly attaching the elastomeric annulus to a supporting structure; means for fixedly connecting the sleeve to a component to be isolated from shock; and a second plurality of disked, disc-shaped annular metal springs stacked to peripherally engage each other along alternate inside and outside edges around the rod means wherein one end of the second spring stack is in longitudinally spaced connection to the other end of the sleeve with the other end of the second spring stack restrained against expansion by the rod means such that rapid acceleration of the supporting structure in one linear direction operates to first compress that portion of the elastomeric annulus disposed intermediate the attaching means and the first spring stack and then to compress the first spring stack while rapid acceleration of the supporting structure in the opposing linear direction operates to first compress that portion of the elastomeric annulus disposed in shock attenuating series with the second spring stack and then to compress the second spring stack thereby attenuating shock and vibration to the connecting means caused by rapid accelerations of the supporting strucuture.

Claim 3

Dependent Claim 178 words

The shock and vibration mount of Claim 1 wherein: the rod means includes a first rod having first and second spaced apart flanges extending laterally therearound with the second flange spaced intermediate the longitudinal extremities of the first rod wherein the elastomeric annulus is disposed around the first rod intermediate the spaced apart flanges; the first metal spring stack is disposed around the first rod in longitudinally spaced relation to the annulus so as to engage that side of the second flange opposing the annulus; the attaching means includes a ring embedded within a groove around the annulus; the rod means further includes a second rod in longitudinally spaced relation to the first rod and having a third peripheral flange extending laterally therearound; the second metal spring stack is disposed around the second rod intermediate the sleeve and third flange; and there is included an elongated shank through the first hollow rod and threadably engaged to the second rod and having a head at the outside end thereof for engagement with the end of the first hollow rod.

Claim 4

Dependent Claim 81 words

The shock and vibration mount of claim 2 wherein: the elastomeric annulus is rubber; the flat ring attaching means includes a plurality of holes around the periphery thereof for attachment to a supporting structure; the sleeve connecting means includes a peripheral flange extending laterally therearound and having a plurality of holes around the periphery thereof for connection to an object requiring shock and vibration isolation, and anti-rotation means are provided to prevent rotation of the sleeve relative to the second rod.
