    I. WlLMOT. Delap's Improvements in Boilers. G, the main steam pipe (as described before), in which is an axis with a spiral flanche filling the pipe. The end of this axis passes through the bend of the pipe, and is there made steam-tight. On this end a pinion or pully, <fcc. is put, which will work a shaft by a cog wheel or pulley, &c., and this may be applied to stir any ingredients in the common boiler to work a pump or any 5 other thing it is found equal to instead of manual labour, and the steam, after the same purpose. The steam pipe is here dropped perpendicular within the boiler, to which are attached one, two, or more horizontal hollow arms; in the ends of these arms are placed the above-described axis with spiral flanches, 10 the pinions acting upon a horizontal circle of cogs which is made fast to the inside of the boiler. An inspection of the Figure will shew its operation fully.
