Abstract: 7454. Stewart, W. J. May 28, 1908. Piles ; p i l e s, driving. - Relates to the method of driving hollow reinforced concrete piles by means of a driver acting within the pile, and formed with projections engaging with projections on the interior surfaces of the pile. The improvements comprise the use of segmental projections 11, Fig. 1, on the driver, and corresponding segmental projections 10 on the pile, or, as an alternative, pivoted levers 13, Fig. 4, which are separated by means of disks 15 on a rod 16, may be caused to engage with shoulders 12, on which are placed cushions 6. A collapsible shoe, Fig. 7, may be employed in combination with these drivers. This comprises arms 19, to which a light mantle 22 is temporarily secured, and movably pivoted to the driver by means of pivots 21 running in slots 20. When the driver is withdrawn, the mantle 22 is left in the ground, the disk 23 rises into a cavity, and the arms 19 collapse. The driver may be constructed of T-irons, Fig. 6, bolted or riveted together and carrying collars or projections, not shown. Specification 28,269/07 is referred to.

Abstract: 14,647. Stewart, W. J. June 27. Excavating; piles.-Excavating - apparatus for sinking concrete and other piles, wells, caissons, and shafts, and for mining and other purposes, comprises a stout outer tube fitted with a suitable cutting-shoe and a sliding inner tube in which the material may be removed. Fig. 4 shows the outer tube 1 fitted with the shoe 2 and having a collar 10 on the inner tube 6 resting on a shoulder on the shoe. The tube 6 and the collar 10 are split to facilitate the withdrawal of the material when the rod 19 is raised. Fig. 6 shows a modified form of contracted mouthpiece for the tube 6. The tube 6 is provided with a number of guide-bars 12 which serve to lock the conical mouthpiece 13 in position. Fig. 7 shows the lower end of the tube 6 provided with hinged jaws 16 connected to the rods 19 by links 11. Quadrant-shaped plates 18 are secured to the upper part of the jaws to close any opening between them and the end of the tube 6.

Abstract: 123,558. Stewart, W. J., and Woolcock, J. Feb. 20, 1918. Concrete vessels.-In reinforced-concrete ships, the reinforcement consists of two parallel networks, the transverse members of which comprise two elements or bars a, b, spaced apart by inclined ties e, such transverse members being adapted to be ber.t to the section of the vessel without altering the spacing of the elements. The elements may be corrugated to permit alteration of length when bending. The longitudinals d, e are supported in the angles between the elements and the ties, as shown. The ties may all slope in the same direction, and they may be bent around the elements a, b. Or the reinforcement may be formed by slotting and expanding the light double-bulbed rolled section shown in Fig. 5.

Abstract: 123,115. Stewart, W. J. Nov. 6, 1917. Concrete vessels. - In the moulding or casting of reinforced concrete ships and other structures, a skeleton comprising metal reinforcement such as is described in Specifications 115,695 and 115,797, is built up on supporting means as a self - contained structure, and the casing or mould a, a for shaping the concrete is attached to the reinforcement b y bolts e and nuts c, which are connected together in pairs, as shown on the right-hand side of Fig. 1, or are linked by flexible connexions d with parts b of the reinforcement, preferably on the opposite side of the skeleton. The apertures left when the bolts e and casing are removed, are subsequently filled in with concrete. The invention is applicable in the case of ship structures where pro-cast reinforced transverse frames cast and matured prior to incorporation in the structure are employed. as described in Specification 122,045.

Abstract: 115,797. Stewart, W. J., and Woolcock, J. May 16, 1917. Concrete vessels.-In reinforced concrete ships &c. a bond for connecting a pair of single reinforcing rods or groups of rods comprises two equal wire ties j, j , Fig. 3, with the ends bent at right angles, and placed on opposite sides of the rods. The adjacent ends are then bent to encircle the rods and are twisted together as shown in Fig. 1. The reinforcing rods of a rib for a wall or ship may be connected together by such ties which also may encircle certain of the rods in the main wall or skin reinforcement, that shown being of the kind detscribed in Specification 115,695.

Abstract: 21,851. Stewart, W. J., and Woolcock, J. Nov. 2. Reinforced concrete. -The reinforcing- bars of concrete piles, pillars, beams, &c. are bonded in sets of three by means of wire ties a, Figs. 3 and 5, the ends c of the wire being twisted together to tighten the loop b on the middle bar of the set as shown in Fig. 1, and the extremities being formed into a fork. The ties may be opened out as shown in Fig. 8 to support the bars at shorter distances. Struts such as flat bars h, k, Fig. 1, may be used between the main bars. According to the Provisional Specification, the ties may be bent completely around each bar and may embrace more than three bars.
