    Delap's Improvements in Boilers. NOW KNOW YE, that in compliance with the said proviso, I, the said Robert Delap, do hereby disclose, discover, and describe my said Inventions by the above Plains or Drawings, and the descriptions thereof hereunder written, that is to say:— I call my boilers (economical, because the fuel necessarily consumed in 5 the various operations of our manufactures is made at the same time to com¬ municate sufficient heat to them, not merely by continuing the flues under and around them (as is common after the fire has performed its usual busi¬ ness), but direct and immediate in the first instance, in addition to those advantages. All the improvements hitherto made in respect to boilers consist 10 in a particular construction of the fire-place and flues with a view to save fuel; but yet they must all have fire applied exclusively to themselves to enable them to perform their work, and there is still an equal (if not greater) heat wasted upon the flues and surrounding work. The peculiar principle of my Invention is that that I avail myself of this hitherto wasted heat, and with it work my boilers, by 15 placing them in the situation of these flues and other work, and also in forming them so as to surround all fires, whether applied to other boilers or any other purpose, so that I may venture to say these boilers consume no fuel, and yet work as well and are as applicable to every useful purpose as any other boilers. Those who use fire for boilers of any description or for other purposes may, with 20 the same fuel they now consume, have a steam (or other) boiler on this prin¬ ciple and construction, which will work a steam engine or perform other pro¬ cesses as well as any boiler whatever. Those who have steam engines already by adopting these boilers may, with the same fire they now use, work their engines and other boilers or perform any other process to which fire is necessary; a few 25 examples of their application this way I shall give by the above Drawings and explanations, which will be sufficient to shew their principle and construction, and that the enormous expence of fuel to work steam engines will be entirely saved to bleachers, brewers, distillers, sugar refiners, dyers, &c. &c. &c., and not only to them but to any one who uses fire for other purposes. They 30 may also be used with equal advantage as open boilers.

They will produce steam of sufficient strength to work any steam engine. Any common boiler may be converted into a steam boiler by adding a cover, the boiler doing its usual work
