    Snowdons Improvements in the Manufacture of Artificial Fuel and Fricks. in part recited Letters Patent, as in and by tlie same, reference being there* unto had, will more fully and at large appear. KOW KNOW YE, that, in compliance with the said proviso, I, the said Thomas Snowdon, do hereby declare that the nature of my said Invention, and the manner in which the same is to be performed, are fully described 5 and ascertained in and by the following statement thereof, reference being had to the Drawings hereunto annexed, and to the figures and letters marked thereon, that is to say :— My Invention consists of a mode of combining mechanical parts into a machine for moulding and pressing artificial fuel and bricks. And in order that 10 my Invention may be most fully understood and readily carried into effect, I will proceed to describe the means pursued by me. * Description of the Drawings. Figure 1 shews a plan of a machine constructed according to my Inven¬ tion; Figure 2 shews a side elevation of the machine; Figure 3 shews a 15 transverse section of the machine taken at the dotted line 1, 1, in Figure 1 ; and Figure 4 shews an end view, partly in section. In each of these Figures the same letters indicate similar parts, a is the main or driving shaft, to which motion is communicated from a steam engine or other power. On this shaft is fixed the wheel b, having two crank pins c, c, 20 fixed at opposite sides thereof, which are intended to lift the two levers d, d, which give motion to the two rams in the two moulds e, e. The two levers d, d, move on the axes f and they only lift the rams g9 g, a sufficient height to mould and press the fuel to the degree desired, other apparatus hereafter described then lifting the rams so as to deliver the moulded and 25 pressed fuel leaving the levers d, d, to descend as they successively are raised to their highest position of action by the crank pins c. On the axis or shaft a, are fixed cams i, L j, j, the shorter ones, first acting on the framed ends k of the connecting rods k1, so as to move them a short distance, so as to bring the sliding covers l> hereafter described, over the moulds; and the longer cams j,j, 30 succeeding in their action on the framed ends of the connecting rods, move the sliding covers a greater distance, and so as to leave the moulds uncovered, and allow of the pressed fuel being raised out of the moulds by the rams when they are lifted up by the apparatus hereafter explained ; and the connecting rods are brought back by projections j\j\ on the sides of the cams j, which 35 act against pins in the framed end of the connecting rods. The connecting rods kl are connected at their other ends to the links m by pin joints, and the links m are attached by pin joints to the cranks n, ny on the vertical
