1,162,686. Vibrators. A. G. BODINE. 15 Sept., 1966 [23 Sept., 1965], No. 41248/66. Heading F2X. [Also in Division E1] In an elongated, tubular steel pile 11 vibrated longitudinally at resonant frequency by sonic wave generator 40 into soil, the penetrating end part has a soil engaging and displacing end face 61 and central feed bore 12 is a supply conduit for conducting wash fluid to the soil engaging end face. The vibrator 40 is in two parts 40a, 40b secured rigidly against opposite sides of the upper end of the pile 11 by bolts 41. Each cylindrical rotor 49 is driven by a jet of air or other fluid under pressure introduced tangentially of the raceway via a nozzle bore 50 supplied by pressure air hose 51. Spent air escapes via ports 54 in side plates 48.
