    Newtons Improvements in the Manufacture of Coke, Qc. for carrying off (from the vessel in which the ammonia is separated from the other gases) the uncombined and combustible gases, such as the carburetted or sulphuretted hydrogen, and by which pipe they may be conducted to jets or burners under the apparatus employed for the concentration of the ammoniacal salts, or under the subliming apparatus, or the steam boiler, where the heat' 5 generated by the combustion of these gases may be usefully employed. These combustible gases may be, by means of branch pipes and jets or burners, distributed under any other apparatus, where they may be consumed. Having explained the principle upon which the present improvements are based, and the object which they are intended to produce, I will now proceed 10 to explain more in detail the construction, arrangements, and operation of the apparatus, whereby the results above mentioned are obtained. In the accompanying Drawings I have shewn the best means with which I am at present acquainted for carrying out the improvements. In Sheet I. the entire apparatus is represented drawn to a scale of one twentieth the 15 real s‘ze, Fig. 1 being an elevation of the apparatus, Fig. 2 a plan, and Fig. 3 an end view of the same. A, A, A, are the coking ovens, of which there may be any convenient number (say twenty). They are similar in con¬ struction to those usually employed in England, a, a, a, are the supply and discharge apertures, serving also for the admission of air. a1, a1, a1, are short 20 vertical flues proceeding from the ovens, and terminating in the horizontal flue B, which is about sixteen inches wide by twenty inches in depth. Coke ovens in England are sometimes provided with a similar flue, which usually conveys the gaseous products to the chimney shaft, and from thence into the atmosphere, but it may be employed for conveying the gases to the apparatus 25 hereafter described. Of course where a horizontal flue of this kind does not exist it must be constructed for the purpose of carrying out the present improvements. This flue should be formed of two small walls b, b, with a roof b\ constructed of brickwork or masonry (see Fig. 4, which represents a section of the flue), or it may be covered with large slabs of firebrick, which 30 would enable the processes of cleaning and repairing to be conducted with facility. In order to economize the heat in this flue the boiler of a steam engine may, if required, be mounted thereon, or the heat in this flue may be applied to the vessels for the concentration of the salts, or vessels for the calcination of the soot, or the subliming apparatus (if hydrochlorate of ammonia 35 were desired to be produced) may be adapted thereto. Into this horizontal flue B the chimney of each oven a1 leads, as above mentioned, and shewn more clearly at Fig. 5, Sheet II. The flue B discharges the gases and other products into the chamber C, which is constructed of brickwork or
