    De Jongh's Improvements in the Application of Coke Ovens to JBoilers, Qc. annexed, represents an end view of one of these plates, a is the nearest the crater; b, the rib; and c, nearest the waterways. The ribs are to be about nine inches longer than the plates on the back side of the crater, for the purpose of being bricked or bound in a low cross wall of one or two courses of bricks across the oven, as by E, Figure 9, Plate II., is represented, which 5 said wall will keep these plates steady in their places; the heat will not so well permit of iron fastenings on that side the crater. In front of the crater I bind the plates with bolts and nuts or cotters, or any other way, to an iron cross bar, crank’d down on both sides into the waterways, or otherwise fastened to the brickwork; these two plates are thus steadily fixed on the top of the oven, as 10 level as they can be got parallel to each other, at a distance of four inches more than the diameter of the crater from each other inside, and so placed as to extend one foot three inches beyond the centre of the crater towards the back (besides the length of ribs), and three feet six inches towards the front from the centre of the crater. Figure IX. represents part of the top of the 15 oven; A, the crater; B, B, the two iron plates before described; C, the cross bar to which these plates are fastened; D, D, the two lengthened ribs ; E, the little cross wall wherein these ribs are confined; F, F, are the gutters or waterways. I then place a cover on the plates B, B, in the following manner, I mean a cover which may be slid over the crater or drawn away from it as 20 occasion may require :—Two iron plates form the two sides of a frame, wherein a brick or stone cover is laid; these frame plates or frame side have two flat sides at right angles, as represented by Figure X. A stands upright, while B is horizontal; and these said plates are to slide with the part B upon that part of the plates marked G in Figure IX. and d in Figure VIII.; the 25 thickness of these frame plates I make five eights of an inch, but they may be more or less; one of these frame plates (which are to be both alike) is repre¬ sented by Figure XI. in Plate II. hereto annexed; the whole plate is about two feet six inches long and of two different heighths, namely, from A to B, six inches long and three inches and a half high ; from B to C, one foot long 30 and two inches and a quarter high; and from C to I), also one foot long and three inches and a half high, all outside measure, which may also vary, altho’ I found these dimensions most proper; a hole is made in the said frame plate within about one inch and a half of that end of it which is intended to be' nearest the front of the oven marked E, for the purpose of attaching to it a 35 stiong iion bar seven feet six inches long, about three inches broad, and two inches and a half thick, see Figure XII.; at one end of the said bar I drill a hole through the broadest side, to correspond with the said hole in the frame plate; about two feet nine inches distant from the centre of that hole are to
