    2 Provisional Player § Jacksons Improvements in the Construction of Furnaces. fire bars, unless such saidbars be arranged and disposed as before stated ; that is to say, by placing one set of bars with their dead plate and bearers within the furnace, as ordinarily practised, and the other or auxiliary set of bars at the outside of the said furnace, and connecting them to the brickwork in the following or any other convenient manner; that is to say, I employ a kind of box or case formed of sheet or of cast iron with two sides lined with fire bricks or lumps. The front of said box or case, being also lined with fire bricks or lumps, constitutes a hinged door for affording access to the interior of the said box or case, the bottom whereof has an opening therein, in which are arranged a set of fire bars, and the other and solid part of the bottom which is next to the furnace is also lined with fire bricks. The top of this box or case serves as a hopper, in which the fuel to be employed is. placed, and rests upon a sliding piece composed of fire bricks or lumps, the drawing out of which allows the fuel to fall on to the bars which are beneath. The box or case thus constructed is connected to the upright sides of the dead plate of the furnace by bolts and nuts, and when in use the fuel is first kindled in the aforesaid box or case, and is then pushed upon the inner set of bars and the dead plate; fresh fuel is then allowed to fall into the box or case, and the smoke therefrom, passing over the clear fire in the furnace, will be more perfectly consumed than heretofore. The furnace bars derive their supply of fuel from the fire in the outer box, the operator opening the door thereof from time to time, and pushing the clear fire forward, and supplying the outer or auxiliary fire with fresh fuel as required.
