    Livingstone s Improvements in the Manufacture of Fuel. NOW KNOW YE, that in compliance with the said proviso, I, the said Alexander Speid Livingstone, do hereby declare that the nature of my said Invention, and the manner in which the same is to be performed, are parti¬ cularly described and ascertained by this Specification thereof, reference being had to the Drawings hereunto annexed (that is to say):— * 5 My said Invention consists,— Firstly, of machinery for compressing or forming artificial fuel into blocks or shapes. Secondly, of a long oven or tube for drying blocks or pieces of fuel, the oven and its flues being constructed in such manner that different parts of its 10 length may be heated to different degrees of temperature, for the purpose of enabling me to pass the blocks or shapes through the various degrees of tem¬ perature to which they may require to be exposed, in order to dry them in the manner required. Thirdly, the exposure of such blocks or pieces of fuel as aforesaid succes- 15 sively to the various degrees of temperature of such an oven as aforesaid, by means of carriages moving slowly along the oven, so that the blocks or pieces may be gradually heated to the required maximum degree for the purpose of drying them, and the heat applied to them for this purpose be again gradually diminished until they are withdrawn from the oven. 20 My said improved machinery for compressing or forming fuel into blocks or shapes is shewn in Figures 1, 2, 3, and 4 of the said Drawings hereunto annexed. Figure 1 is an elevation of the machine ; Figure 2 is an end view of the same machine; Figure 3 is a plan of the machine; and Figure 4 is a section 25 of the same, as taken through the line L, M, Figure 3, similar parts in each of these Figures being marked with similar letters, a, a, is the revolving table; b, b, are the rollers; c, c, c, c, are arms, each of which projects from the body of the roller, and is hung by the pin d; e, e, are the shafts which carry the rollers, and are supported and kept in their places by the standards 30 f f which are fitted with brasses, and secured by straps and cottars, g, g, is a spur wheel acted upon by the screw pinion D, which receives its motion from the steam engine, i, i, is an oblong pipe which conveys the small coal from the pug mill to the table of the machine a, a, a. On this table, at an angle with the rollers, are teeth 2, 2, which act into teeth on the roller, and 35 thus turn the table on the upper side, while the teeth on the under side of the table, acting into the teeth of the under roller, is turned by it. X, X, is a lever and counterbalance weight to enter the hole in the table, and lift up the compressed block of fuel. The end of this lever acts into a series of inclined
