ABSTRACT:
Resilient positioning apparatus for sustaining repeated shock loads from heavy work pieces, with ability to reposition work pieces accurately and quickly with negligible loss of accuracy after long service. Apparatus has telescoping assembly having two portions which can be accurately positioned relative to each other and a gas cylinder which has a partition cooperating with one of the portions. The partition defines a chamber with the portions of the telescoping assembly, and the chamber is exposed to pressurized gas which forces the partition, and with it the telescoping assembly against a datum. When the telescoping apparatus is subjected to shock load from a work piece, it is momentarily shifted off the datum, thus cushioning the telescoping assembly, and is then quickly returned due to force from the gas cylinder. The invention is simple and eliminates complex valving associated with shock absorbing hydraulic circuits and is not subjected to buckling under compression loads.
