Abstract
Abstract A jacket member is placed over a bar which forms a mandrel and is acoustically coupled thereto by means of adjustable couplers at a plurality of points therealong. A sonic oscillator of the orbiting mass type is coupled to the mandrel and driven at a frequency such as to set up resonant standing-wave vibration of the mandrel. Sonic energy is thus coupled to the jacket and in turn into the earthen formation into which the jacket is to be installed, thereby fluidizing the earthen material and causing the jacket to be driven into the ground.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
35 words
The device of claim 1 wherein said bar member is a mandrel having a plurality of successively stepped sections along the length thereof, running between the oscillator and thE end opposite said one end thereof.
Claim 2
Dependent Claim
37 words
The device of claim 1 wherein said jacket member is corrugated, each of said coupling means being positioned with an end thereof longitudinally spaced from one of the jacket member corrugations to form a rectifier gap therebetween.
Claim 3
Dependent Claim
68 words
The device of claim 2 wherein said jacket member is corrugated, each of said coupling means comprising a bushing member removably attached to the mandrel, each of said bushing members being placed along said mandrel with one end thereof at a position where a pair of said sections join, a rectifier gap being formed between said one end of said bushing member and a corrugation of said jacket.
Claim 4
Dependent Claim
41 words
The device of claim 4 and additionally including removal tip means attached to the end of said mandrel opposite to the oscillator-coupled end thereof for providing a predetermined extension to the mandrel to adapt it to the length of the jacket.
Claim 5
Dependent Claim
48 words
The device of claim 3 wherein each of said coupling means comprises piston means mounted in said bar member for motion radially thereof and means for driving said piston means to a position spaced from an associated corrugation of said jacket member so as to form said gap.
