    Abstract: 8488. Stewart, W. J. April 8. Piles; piles, driving. - Hollow wooden and other piles, which may, after driving, be filled with concrete, are constructed of stout longitudinal ribs 1 alternating with lighter ribs 2 and connected together, ior example, by means of stays not shown in Fig. 2. A light sheathing 4 of wood or other suitable material is connected to the ribs; and on the outside of the sheathing are secured longitudinal pieces 5 of hoop iron &c., to the exterior of which are fastened hoops 6. The shoe, which consists of a baulk of timber 7 having an iron or steel point 8, is attached to the ribs 1, 2, and the sheathing 4 and vertical pieces 5 may also be brought down over the shoe. The pile is driven by means of a core provided with fixed or adjustable horizontal or longitudinal ribs which contact with the lighter ribs of the pile. Fig. 8 shows a hollow core 10 with ribs 11 which are made to collapse inwardly by means of toggles 16 operated by a rod 17. Fig. 6 shows a solid core 10 projecting through the bottom of a pile and provided with shoulders 12, as described in Specification 7454/09, or with projections 14, 15 for assisting in pulling the pile downwards.
