By this circumstance the water comes at first into a part which is exposed to the most direct action of the fire, and only rises into the boiler at the boiling temperature, so as not to condense the steam which is generated therein. The pipes and trunks above mentioned may be made either of wrought or cast iron or of copper, but I prefer the wrought iron for those parts where the fire operates, as being more durable. It must be remarked, that where copper is used for the trunks and pipes, the boiler must be wholly made of copper, to prevent the metals destroying each other by oxidation. The trunks and pipes may be either of a cylindrical, oval, or square form, or any other form which may be considered most convenient. Having already described the nature of the said Invention in such a manner as to enable persons (conversant with works of a similar description) to put it in practice, it remains for me to state what I con¬ sider as constituting my claim; for I do hereby declare that I do not make claim generally to the employment of tubes, pipes, or trunks of metal situated under a boiler and connected therewith, such apparatus having been before used, but I confine my claim to the new mode of combination and arrangement of the said trunks and pipes passing on each side of the fire-place or furnace and commu¬ nicating with the boiler in the manner herein-before described and set forth, such new mode of arrangement and combination being very effective in accelerating and increasing the production of steam in the boilers generally. The form and proportion of the parts may be varied according to the discretion of the work¬ men, still producing the same effect. 5 10 15 20 In witness whereof, I, the said Richard Ormrod, have hereunto set my hand and seal, the Third day of July, in the year of our Lord One thousand eight hundred and twenty-two. RICHARD (l.s.) ORMROD.
