Fig. 2 shows a sectional elevation of one of these improved vessels, in which a u represents the vessel, on the top of which there is a perforated plate A, and on the lop of this plate there is stretched a piece of vulcanized india-rubber c; d is an hemispherical vessel forming a cover to the whole, which are firmly bolted together; within this last vessel the inventor proposes to compress atmos- pheric air to about two atmospheres, or thirty pounds, which forms a re- sistance or elastic cushion for the water to press against. By this ar- rangement it will be seen that the water in the aforesaid vessel does not mix with the air ; Ihe consequence of which is, that the air cannot pass off from the vessel through the pipe and form the crackling noise which is so frequently heard when working engines of the ordinary construction, llx air in the air-vessel being kept entirely distinct from the water.
