    Newton's Improved Apparatus for Consuming Smoke in Furnaces. I place an arch of brickwork within the furnace immediately behind the fire- door, and having perforated the arch with two or more holes I insert small pipes within the same, causing them to extend a short distance into the furnace. The outer ends of these pipes I connect by means of branch pipes 5 with an air tube, this latter being supplied with a current of air by an ordinary fan placed in any convenient position ; a valve is also placed between the fan and the jets in any desired position to regulate the admission of the air. The above-named apparatus may be used either by itself, for the purpose of smoke consumption only, or in conjunction with my “ Improved Steam Gene- 10 rator, for which I obtained Letters Patent bearing date March 24, 1866, No. 878, with the double object of consuming smoke and generating steam, in the latter case the same main or supply air tube may be made available for both. I prefer, however, in some cases not to put tubes through the arch above spoken of, but to put them behind the ordinary bridge; such tubes to 15 be made of clay (by preference), the largest diameters being, say, four inches, and the remainder two inches, or such diameter as may be accommodated in the flue. These tubes may be of the length of three feet, or two feet six inches, if desired. The purpose of my Invention is either to use the apparatus named by itself 20 or in conjunction, as before stated, with my improved steam generator, for which I obtained Letters Patent, bearing date March 24, 1866, and which said Patent was sealed August 7, 1866. In order, however, that my Invention may be the better understood, the features of it may be seen by reference to the accompanying Sheet of Drawings. 25 It will be seen that the illustration shows the major portions of my previous Patent before referred to, No. 878, A.D. 1866, that is to say:— Description of Drawings. Figure 1 shows a front elevation of the subject-matter of my previous Patent in combination with my present one ; Figure 2 shows a section in which my 30 improved apparatus, as described in my preferred arrangement, is illustrated ; Figure 3 shows the arrangement I prefer for the flues, the tubes being shewn therein in section. Letters A denote the pipes furnished with air from the pipe B by means of the fan C. The air so supplied is passed through the small pipes d, as will 35 be seen on reference to Figure 2, into the furnace. The tubes before men¬ tioned placed behind the bridge effect the result that I desire, viz., combustion of smoke. Ilaving now particularly described and declared the nature of my Invention,
