    Abstract: 113,375. Stewart, W. J., and Woolcock, J. May 2, 1917. Piles.-In forming concrete piles, reinforced or otherwise, by driving a tube, filling the tube with plastic concrete, and then withdrawing the tube, means inserted in the tube before filling are withdrawn after filling so as to break up any arch in the concrete and also to relieve friction between the concrete and tube during removal of the latter. In the form shown in Fig. 1, the disturbing means comprise pivoted triangular links e, e carried by a tube &c. C. The form shown in Fig. 2, for use where a central member forms an obstruction in the pile tube, comprises tubes h, h assisted by a cross-piece i and carrying pivoted diamond links j. Where the concrete is inserted in a semi-plastic state, water may be added through the tubes c, h, h , which may be perforated, during their removal.
