Abstract: 1345. Duckham, A. M. Jan. 17. Clinkers, removing.-In apparatus for clinkering gas-producers, furnaces, &c., of the kind in which a temporary fuel-support is inserted above the grate to permit of the removal of clinker between the temporary support and the grate by a poker, the bars of the temporary fuel-support are mounted in a cross-head or the like to form a grate, which is driven into and removed from the fuel bed by poweractuated means and is mounted detachably on a carriage. The temporary support may receive a reciprocating movement during its insertion and may be mounted on the same carriage and operated by the same power means as a poker, such as that described in and shown in Fig. 1 of Specification 23,862/12. The cross-head h, to which the grate-bars n are secured, is supported on angle-iron rails e<5> carrying pulleys h<2> round which pass chains i, attached at one end to reversible hooks h<3> on the cross - head and at the other end to a cross-bar k inserted in a slot in the end of the hydraulicallyactuated poker b. When the apparatus is not in use, the poker is fully home in the. cylinder a and the cross-head h is in the position A. To insert the grate, the poker is forced out of the cylinder a, and the cross-head h and bars n are drawn towards the producer by the chains i and pushed into the fuel bed. The chains i are then detached from the hooks h<3>, and the carriage is reversed in order to effect the clinkering by the poker. To remove the grate, the poker is again placed in the position shown, but the chains i are attached directly to the hooks h<3>. The cross - head is provided with two channels h<5> for the circulation of cooling-water, one channel communicating with the hollow bars n, while the other communicates as shown with co-axial bars. A modification is shown in Figs. 4, 5, and 6. in which the bars n are reciprocated during their insertion. The cross-head h is provided with two rearwardlyextending rods h<6> passing freely through a transverse member of a carriage o, also adapted to slide on the rails e<5>. These rods are surrounded by springs h' and prevented from being withdrawn from the carriage o by nuts h<8>. When the carriage o is drawn forward by the chains i, the racks q on the rails e<5> rotate the toothed wheels p, r and the shaft s carrying a cam-wheel t, which, in conjunction with a grooved wheel u, grips a rod v secured to the cross-head h. The cross-head with the grate is pulled backwards and the springs h<7> compressed. When the portion of the cam-wheel t of short radius begins to pass the line joining the centres of the cam-wheel t and wheel u, the rod v is released and the springs h<7> force the grate-bars suddenly into the fuel bed. This reciprocating action is repeated so long as the wheels p are engaged with the racks q. The hydraulic cylinder a, Fig. 1, containing the piston for operating the poker is mounted in a cradle d pivoted on the axle d<2>, which is adapted to turn in bearings bolted to the uprights e<4> of the carriage frame e. These uprights form guides for the carriage axleboxes f, which support the frame by means of screwed spindles g passing through blocks e<1> bolted to the uprights, and carrying nuts g<1> adapted to be rotated on the spindles g by a hand-wheel on the spindle g<2> and bevel-gearing, for the purpose of raising and lowering the frame. The transverse member e<2> of the frame carries a screwed boss in which works a spindle c<3>, resting on a castor-wheel and serving to tilt the frame on its axle. The carriage is anchored by chains m, m<1>.
