Abstract
An isolation system for a sensitive component or apparatus affixed to a mortar tube comprising a barrel mount assembly which supports two parallel shafts. A plate parallel with each axis of the two shafts positions four bearing carrier blocks, two each containing a sleeve bearing which rides on each of the shafts to allow the plate assembly to slide freely along the length of the shafts and support an isolated cage. During firing, the travel vector is decoupled from the cage by the shafts as they move with the barrel through the bearings leaving the cage assembly in free space. The cage then accelerates under the force of gravity over the distance of the displaced travel of the shafts back to its rest position landing on steel springs or dampers, each on a shaft and seated against the lower flange end of the barrel mount assembly.
