    Jones’ Improvements in Means for Consuming or Preventing Smoke. therein particularly describing and ascertaiug in what manner the same is to be performed or carried out in practice. Description oe the Drawing. The Drawing shows the application of my Invention to a Cornish boiler, by a longitudinal section in which A represents the flue or 5 passage of such boiler; B, B, being the fire-bars of the furnace, and the arrows represent the course of the fluids or gases from the furnace which pass over a bridge D and are deflected by the drop or inverted partition or bridge E into a combustion chamber E which is formed by another partition or bridge G. Air being admitted into it through ash- 10 pit H and regulating damper K, that enters the combustion chamber at an orifice L which extends across the flue or passage, allowing the air to become mixed with the unconsumed gases in the combustion chamber, thus preventing the emission of smoke. Different dimensions of combustion chambers may be required for 15 different sizes of furnaces, and a regulating air damper may or may not be used to admit and regulate the quantity of air into the said chamber, as this can be done through the fire hole doorway. Having now particularly described and ascertained the nature and object of my said Invention, and in what manner the same is to be per- 20 formed and carried out in practice, I hereby declare that I claim the Invention of “ Improvements in Consuming or Preventing Smoke,” the nature or character whereof is herein-before described by the words prececding the words <f Description of the Drawing,” which said Invention is illustrated by the Drawing accompanying these Presents. 25 In witness whereof, I, the said David Jones, have hereunto set my hand and seal, this Twenty-sixth day of September, in the year of our Lord One throusand eight hundred and seventy- four.
