I, ROBERT HUDSON, of Adwalton, near Leeds, in the County of York,.
Engineer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MEANS OR APPARATUS FOR THE GENERATION OF STEAM," to be as
follows:-
I employ a boiler fixed in a vertical position, the outer shell of which is
cylindrical, having its lower end somewhat of a conical or spherical form, and
terminating in a cylindrical tube, which tube passes through the fire grate, so
that any sediment in the boiler may settle down below that part of the boiler,
subject to the heat of the fire, which sediment may, at the discretion of the
stoker, be blown out by means of a mud cock. An annular water space is

page_text: formed in the boiler by means of an internal chamber, which chamber also acts
as a steam chamber by communicating at its upper part with a steam dome on
the outside shell.
The flue from the fire-place is coiled in a spiral or corkscrew form round the
boiler, and passes thence to the chimney.
