The above-men¬ tioned fire-door is cased or framed in by side plates, and has underneath it a curved plate on which the fuel rests while being pushed into the fire by the said fire-door ; the front or greater part of the afore-mentioned curved plate is fixed on hinges or joints to the side plates herein-before mentioned. In 5 order to support the said curved plate I fix a piece of iron three sides of a square to the afore-mentioned side plates so as to swing under the curved plate; by removing this piece of iron the curved plate is made to drop on its hinges or joints. I propose also to use a hopper to contain the fuel when the aforesaid fire-door is used for supplying the furnace with fuel. Between 10 the said hopper and the afore-mentioned fire-door I place a valve or regulator to regulate the supply of fuel to the furnace; this valve or regulator is so * fixed as to fall close when the hopper is empty; on each side of the said apparatus is a small door for the admission of air and fire-irons.
