Abstract: 27,369. Kudlicz, J., AndrÚ, A. C. F. von, and Friederici, H. R,. O. Dec. 14. Mechanical stoking. - Relates to apparatus intended for use with locomotive, marine, and other boiler furnaces, by which coal dust or unscreened c o a l, and particularly unsorted coal, is distributed o v e r the grate evenly or unevenly as desired, so as to economize fuel and reduce the formation of smoke. The fuel is fed from a hopper 3, in the upper part of the apparatus, to the lower part of the apparatus which contains a rotatory ejector formed with an enlarged boss 12, Fig. 8, and short throwers 13 of the form shown. The fuel is struck by these throwers as it falls through a space x which is arranged below the feed hopper so as to receive any fuel which has not been properly struck and to allow it to drop again on to the throwers. These throwers are protected underneath by a casing 17, so that fuel cannot pass under the operating-spindle 11. A locomotive apparatus is provided with duplex adjustable fueldeflecting or spreading and distributing plates 27, 37, Figs. 6 and 8, while a marine or stationary boiler apparatus is provided with a single deflecting-plate 74 which may be oscillated mechanically. The whole apparatus is mounted on a back plate 91 which is hinged to the furnace front, to enable it to be swung away from the charging hole with which an aperture 7 coincides when the apparatus is in operstion. The coal may be fed from the hopper by rotatory feeding rollers 8, 9 which are grooved or provided with arms 10, as shown, and are operated, from the ejector shaft 11, by the silent-feed, eccentric, and toothed gearing and linkwork shown in Fig. 6. The feed is regulated by a pivoted slotted piece 59 clamped in adjusted position by a screw 86. The rollers may be arranged as shown or otherwise, and the upper roller may be an idle one. Other feeding arrangements may be used, such as a reciprocating slide. A coal-spreading device 26, Fig. 8, may be provided on a hinged door 18. The locomotive fueldeflecting plates 27, 37, Fig. 10, may be adjusted by levers 31, 43, Fig. 5, the fuel being deflected and spread by depending projections 28, 44. The oscillating deflecting-plate 74, Fig. 16, may have a convex under surface, either continuous or stepped, and may be operated by a cam 75 and a weight 83. The cam-operated lever 77, 81 rides loosely on the shaft of the deflecting-plate, and the parts are adjusted relatively by a screw 80 engaging an arm 79 on this shaft. Shields 84, Fig. 8, are arranged between the deflecting-plates and the hopper outlets. To facilitate the removal of the deflectors from the fireplaces, they may be mounted on pivoted frames, or the whole stoking-apparatus may be double hinged. A side lever may be provided to operate fastenings which look the apparatus in its operative position. Hinged air-admission and other doors, and air admission, observation, and stoking openings are provided. A striking plate may be mounted at the bottom of and just inside the charging opening, or fixed to the hinged plate 91. The shaft 11 may carry part of a clutch to engage a similar part on a steam engine shaft.
