    Ingledew's Means of Effecting a Savmg in the Consumption of Fuel, <fyc. 1 at all times thenafter during tlie term of fourteen years therein expressed, ] should and lawfully might make, use, exercise, and vend my said Invention within that part of His United Kingdom of Great Britain and Ireland called England, Ilis Dominion of Wales, and Town of Berwick upon Tweed, and also in all His Colonies and Plantations abroad, in such manner as to me, 5 the said James Ingledew, my exors, admors, and assigns, or any of them, should in my or their discretion seem meet in. which said Letters Patent is contained a proviso that if I, the said James Ingledew, should not particularly describe and ascertain the nature of my said Invention, and in what manner the same is to be performed, by an instrument in writing under my hand and seal, 10 and cause the same to be inrolled in His Majesty’s High Court oF Chancery within six calendar months next and immediately after the date of those His said Letters Patent, then the said Letters Patent, and all liberties and privileges whatsoever thereby granted, should utterly cease, determine, and become void, anything therein contained to the contrary in anywise notwith- 15 standing. . HOW KNOW YE, that I, the said James Ingledew, in compliance with the said proviso, do hereby describe and ascertain the nature of my said ] Discovery or Invention, and in what manner the same is to be performed, used, and operate, by the Plans or Drawings hereto annexed, and in the follow- 20 ing description thereof, that is to say :— My Discovery or Invention consists in the application of chalk, lime- j stone, and other calcareous substances convertible into lime, by means of heat, as auxiliaries to the ordinary articles of fuel in the carbonizing of coal for gas, in heating the boilers of steam engines, brewers’ and distillers’ 25 coppers, sugar bakers’ pans and furnaces wherein great heat is required. The manner in which this auxiliary heat is obtained is by employing the ordinary material of fuel not only to the purposes to which it is primarily directed, but to the further purpose of calcining the chalk, limestone, or other calcareous substance, and thereby concentrating and keeping in action a most powerful 30 heat in aid of the ordinary operation of the fuel, so that a less quantity thereof is actually required. This process may be applied in such manner as the skill of the manufacturer may best suggest, reference being had to the uses and purposes intended. In the application of the heat thus produced to the gene- j ration of gas, I apply the articles above mentioned in a species of lime chamber 35 above the ordinary fire, the retorts being placed in this chamber; and I have found the chamber, of which I have subjoined Drawings, N° 1, with the proper flues, &c, to answer most effectually. The fire, as before observed, is placed in a furnace beneath the lime chamber, and either coal, coke, wood, or other
