    Nevilles Improved Methods of Generating Power hg Means of Steam, fc. pipe into the bucket which is above it, and so on until any number of buckets are filled, but which process of the steam passing through the pipes is only necessary to start the engine in the first instance; these buckets are made of such a size as to revolve freely within the internal space of the said castings 5 A, B, C, D, E, F, Figures 4 and 5, and which space is to be filled to any required height (corresponding to the intended quantity and elasticity of the steam or other fluid which is to be admitted therein) with any dense fluid that will bear a greater or higher temperature than that of the steam or other elastic fluid to be employed in the said engine, without being decomposed or converted 10 into vapour; then if such dense fluid be heated to the required temperature, and steam or any elastic fluid whose pressure is greater than the weight of the dense fluid in the engine, be admitted through the steam pipe N, N, the said elastic fluid will instantly ascend therein and occupy one of the lower buckets, and will displace the denser fluid therein, which will increase the alti- 15 tude of the same in the engine, and the elastic fluid will successively continue to occupy each bucket by passing through the pipes 0, z, z9 z, z, z, z, z, z, z, z9 z, z, z, z, z9 z9 z, 0, z, z, z, Figure 5, until the pressure of the steam or other elastic fluid is equal to the resistance or load to be overcome by the engine, and it will then commence its motion in the direction above described; 20 as each bucket passes the pipe N, N, in succession, it will receive the necessary quantity of steam or other elastic fluid. This quantity will depend on the elasticity or pressure of such fluid, and its admission through a cock or valve at a is regulated by a centrifugal governor, or other of the well-known con¬ trivances to regulate the motion of the engine. The power of this engine is 25 communicated from both or either of the shafts or axles P, P, which are turned true, and pass air-tight through the stuffing boxes b, b, b, b. Figure 4, and b, b, b, b, Figure 12. The effect of this engine will be similar to the first described, and produces a rotary motion. I have introduced these two examples, which are sufficient to elucidate the first part of my said Invention, 30 namely, the application of steam or other elastic fluids by their ascent in those denser fluid mediums which are commonly termed non-elastic, and of employing their expansive properties in any proportion which may be considered desireable; and,I reserve to myself the sole right and adoption of this part of my Invention, without confining myself to the various and different modes of mechanical appli- 35 cation of which it is capable. I declare the second part of my said Invention to consist in increasing the quantity or volume of steam or other elastic fluid em¬ ployed by means of heat, without augmenting its elasticity or rendering the same dangerous. This I effect by causing the steam or other elastic fluid to pass or ascend, either by means of pipes or otherwise, through any fluid or other medium
