Abstract: 12,605. Preston, F. G. P., and Ralston, G. C. June 3. Ships' ashes, discharging. - Ships' ashes and clinkers are crushed and passed into an apparatus from which the contents are discharged into the sea by air or fluid pressure. In the form of apparatus shown in Fig. 3, the ashes are crushed between the hardened steel ribbed faces of a fixed jaw o and an oscillating jaw d, which is operated by a toggle e, toggle-link f, bent lever g, h, and eccentric and rod i. The crushed material passes between the ribbed roller p mounted on the shaft j of the eccentric i and the roller q mounted on a shaft adjustable by screws. The material then passes by an opening 3 into a rotating plug cock 1, shown in section in Fig. 4. Opposite to the opening 3 is a chamber 4 with lateral holes 5 and a port 6, which, when it comes opposite to the port 7, admits compressed air, driving the ashes out through the opening 18. The plug 1 may be rotated continuously by a chain, or intermittently by an arm x<1>, Fig. 1<a>, and roller x<2> acting on a star-wheel w<1>. A modification of the discharging-apparatus is shown in Fig. 12. The ashes, after passing through a rotating plug cock 23, fall on to a piston 27 moving in a cylinder 26 passing transversely through a rotating cylinder 25. Compressed air is admitted by an opening 32 above the piston 27, so that, when the cylinder 25 has turned through 180‹, the piston 27 is driven to the other end of the cylinder 26, forcing the ashes before it. In another modification, a cylindrical chamber 40, Fig. 15, is placed below the casting 48 containing the crushing-apparatus, with a revolving disc at the top having a sector-shaped aperture which registers with a similar aperture in the bottom of the casing 48. At the bottom of the chamber 40 are a similar pair of discs, the revolving discs being driven from the shaft j by bevel gear and chains. Compressed air is admitted into the chamber 40 by a pipe 16 and sliding valve 55 operated by a crank 56. In another modification, a plug revolving in a cylindrical or conical shell 60, Fig. 22, has three taper blades 62 on a hollow fixed axis 66. Compressed air for discharging the ashes is admitted by means of a slit in the axis 66 and openings 64, 65, 66 between the blades. A further modification is shown in Fig. 25. Below the casing 48 is a receiver 71 with slides 70, 72 at top and bottom worked by the pistons 74, 76 in the compressed-air cylinders 73, 75, so that, when one is open, the other is shut. The movements of these pistons are regulated by the valve shown in Fig. 26. Two discs 80, 81, turning in seatings 78, 79, put the two ends of the cylinders in communication with the supply pipe 87 or the exhaust pipe 85 through the pipes 88,89 and the passages 82, 86, Fig. 28, in the discs. The discs 80,81 are turned by the pins 98, 100, Fig. 25, striking against the arm 99 on the spindle on which they are set. A projection 94 on the rod of the piston 74 opens and shuts a cock 97, which admits compressed air to the receiver 71. The slides 70, 72 are furnished with sloping projections 90 which bear against similar projections 91 and keep the slides tight against the ends of the receiver 71. Whatever form of discharging-apparatus is used, air at a lower pressure than that used in it is admitted to the exit passage beyond it, and the outlet may be closed by a hinged, weighted, flap valve which opens to discharge the ashes.
