    Foard's Fyipvovcd 3£€thod of Supplying Fusl to StoaiTi c^iyino Foilsvs^ ^c. stops or supports, their upper ends passing through openings formed at the sides of the chamber or coking oven, and such upper ends have at all times a tendency by their springs to remain within the chamber or coking oven, as will readily be understood, on examining the Drawings now under descrip¬ tion. The door at the front of the chamber or coking oven is divided into 5 two parts, the smaller part being at the top, and this is to allow of the plate 'y being withdrawn, when a fresh supply of fuel has been fed into the coking- oven or chamber. In working this arrangement, supposing the fire to have been at work some time, and that the plate v, resting on the piston c, has been raised to its highest position, it will have passed the upper ends of the spring 10 or lever stops or supports, and will be supported thereby, there being notches formed in the piston opposite the spring and stops or supports, so as to allow the spring stops or supports coming under the plate v, so soon as that plate has passed above those stops or supports ; the burning fuel will now be sup¬ ported above the plate i;, and the piston may be lowered down in order to 15 admit of a fresh supply of fuel to the chamber or coking oven through the door way in front, as before described. There being a plate v first placed on the piston, the chamber being charged, the doors are then to be closed, and the piston raised so as to bring the fresh supply of fuel under the plate v, when the upper part of the door is to be opened, and the upper plate v drawn out by 20 a hook or other convenient instrument, and* in this manner is the furnace to be worked. I have not thought it necessary to shew furnaces applied to other than a steam boiler for a fixed steam engine, as it is well known that a furnace for locomotive or for marine steam engines, and for a brewer’s copper, or for other boiling and evaproating vessels, will not materially vary from that shewm; 25 indeed the arrangement of furnaces are so similar one to another for whatever ])urpose they may be applied, that a workman capable of constructing a furnace for a particular object will readily apply my Invention thereto, from the descrip¬ tion above given, aided by the Drawings annexed. I will now describe my Invention as applied to open fire-places. Figure 9 30 shews a front view of a cooking range having my Invention applied thereto, and the parts are similar to the arrangements shewn in Figures 1, 2, 3, 4, and 5, being only so modified as to adapt them to this description of fire-place. But I would remark, that if preferred, the plate v may be used in place of the plate /, which is shewn by varying the parts accordingly. Figure 10 is a transverse section of 35 Figure 9. The parts employed in applying my Invention, as shewn in Figures 9 and 10, being marked with the same letters of reference as those of Figures 1, 2, 3, 4, and 5, the description of those parts before given will be sufficient to describe the nature and use of tlie parts shewn in Figures 9 and 10, when
