.Be it known that I, EDWARD N. Dicken- SON, acitizen oi'the'United States, and a resident of Stova lhj Granville county,- North Carolina, h aye iny ented certain new and use .ful improvements.inirocesses of Manufac turing Combustible Geses,

of which the follhisinvcntion relates to an improved processjfor economically IIlflIlllftlGiiUIlfliCOIllbllS- it is We l known that the ordinary 0 era tion in manufacturing water gas can on y be practically carried out, when coal is used, by the employment of anthracite or similar hot material. it cannot be successfully practiced in on olas by the use of bituminous coal. (in t e other hand bituminous coal can lie'distilled to produce ordinary coalgas leaving'a coke which is generally sold in the market for household, consumption or similar purposes. Further, in the ordinary process of manufacturing water gas, during the operation known as blowing u an enormous amount of heatescapes to t e atmosphere and is wasted;v I propose to utilize thewaste heat from a water gas cupola for the. coking.

of bituminous coal while alternately roducmg water gas from said cupola-an duced'in the coal gas bench. The coal and water gas so produced, I further propose to mix and bring together into a'comrnon mam or holder, whence they may be utilized for heating purposes. 1 further propose to add to the coal or water gas, if desired or to both, sufl'icientilluminant to produce illuminating gas if desired, and I "further propose to utilize the wasteheat cf the oupola in the process of blowing ,u attergitlhas aided in the distillation of dis. coal, *in heating an ordinary checkenwork which may he subsequently used for heatin the 'air or producing steam to be used in t 1e cnpola in the processes of I making water a'sfand I further repose to aid-in the disti lation of the coal "ycausing "the hot water gas to pass throughfor overthe" same on its way to the holder or mains.

r The cupola'A s provided with an air blower and inlet G for blowing up which is shown separate from the blower G for con venience of, illustration, though, manifestly but one blower with suitable connections The cupolaA may, further be provided with an oil pipe H for feeding oil, if desired.

It is also provided ing plunger forforcing out the coke, or ii desire with a feeding funnel J which is to have suitj able valves and a distributer, as shown, if de- 5 sired. The pipe K connects with the heat absorber, as shown, and may have the branch K. for the supply of steam, if desired. The outletpipe L is provided with three branches; one L connecting with the heating chamber surrounding the distilling retort, another L entering the' chamber of the distilling retort,

while the third L' may connect directly with the mains or place of utilization of the gas or may pass into the scrubber and puri-* fier, as desired. It is manifest that all three branches L L" and L would not be re quired unless itis desired to practice the processcs for which they are designed The distilling retort B may be of any ordinary form, such as the coal gas bench generally used, or if desired, the present form of Lowe generator, see U;S. Patent 711,905, for the production of what is, known as Lowe anthraeite may be employed. In this case the external heating chamber M. is ofcourse omitted, but the gas producedmay contain a certain amount' of nitrogen, as will be presently described.

When the chamber. M is omitted and replaced loo 1 by the well known Lowe generator, the retort is heated by the operation of the latter. In. case the Lowe style of horizontal retort is emp1oyed,the coal. may be fed from above in the well known manner, but, otherwise it is fed into the endor ends of the retort.

The carriage E is arranged on rails, as shown, to receive the contents of each of the F may also be arranged on rails to operate at each retort at will. Air" outlet is provided with the retort B by the pipes N, L and N passing to the scrubber and purifier D or di. rectly to the outlet as desired. The retort B is likewise provided with the inlet T which may be utilized for the introduction of oil. The heating chamber M is provided with the pipe D assing to the bottom of the heat absorber which, itself is rovided with outlet R communicating with the atmosphere. enters the upper part of the checker-work which is also provided with a pipe S through, which the steam My roeess as carried'out'bjtfmecannow be rea ily understoodf. The cupola A being assumed to be charged with coke in a state of combustion, and the retort B'with a distillable coal or similar material, my o eration is as follows: Air either hot or'col is blown This, in case the ordinary coal gas bench is is 'caused to through the pi es L, into the heatingchamber M thereby eatingand distilling the coal in the retort B after passing around the retort B, thehot gases pass throu h the pipe P and thence esca e through the outlet or purge valve R to t e atmosphere.

pass by pipe N e1ther' directly to the place of utilization through the pipe 0, or through thepurifier Dv to a holder. As soon as the process of blowing up is finished, steam is admitted to the bottom of the cupola through the pi e K either through the inlet K, or it may be generated in the heat absorber C by spraying water throu h the pipe S. The pipes L, L L and 5 are respectively provided with valves w, 0: as and Between the pipe N and a nozzle N leading intoj'the base of the purifier D is a -valve These valves are opened and closed to permit the gas to pass through the several pipes with which they cooperate into theycomponent elements of the apparatus, or to the main in accordance'with the operation desired to be pursued. The water gas produced may pass directly through the outlet 0 or the purifier D, but preferably. passes by the ipe it into the coal gas retort where it mingle with the coal gas, and by its heat aids in ihuqlistillation of the same. In this case the resulting gas escapes as before, either through the pipe 0 or the purifier. When the coal has been distilled, the valve 0: of the pipe L is closed, the retort B opened in the usual way and the coke meass after combustion .other section at will.

Meanwhile, the gases chanically or manually caused to fall into the carriage provided with closing valve W, and

is then conveyed by the carriage to the cupola i the valve W and 'the valve in the hopper pipe J, the coke is readily fed into the desired cupola, the retort B being then recharged, and the a paratus prepared to repeat the process. When the water gasfrom the eupola is to pass directly through the outlet 0, the valveszc and 90 are 0 ened, and the valves as, m and m are close If the gas is to pass to the purifierD the valves at, m and :0 are closed and valves as and x o ened. When the gas is to pass into the retort the valves w, x and m are closed and valve ac opened; If the heating gas is to pass into the heating chamber M, the valve-a: is opened and the remaining valves closed, but under certain conditions, or when it is desired to have the gas also ass into the retort at the same time, the va vs 00 may be opened. It is of course obvious that a separate heat absorber and purifier is not required for each retort, but the pi es from the cupolas and retort's are lateral y connected in the usual way so that each may be connected to any is intended to be illustrative, and the pipes and connections would be arranged in practice in the manner Well known to all gas engineers and all pipes would be provided with proper valves for controlling heated ases.

In case it is desired to produce with some admixture of nitrogen than during the period of the blow off, the gases from the cupola A may be caused to pass throu h the ipe L into the coal in the retort B an may he carried away jointl with the gases pro. duced by this distillation, but in this case, the resulting gases will be rendered'impure by the nitrogen and products of combustion so mingled with the resulting gases.

What I claim as my invention and desire to secure by Letters Patent is 2 A process of producing combined coal and water gas consisting of blasting a bed of fuel to incandescence by means of a fluid and at the same time heating externally by the blast gases a retort containing coal thereby dis tilling the coal gas and at the same time utilizing the blast gases to heat a checker-work chamber and simultaneously heating the blast fluid passing through said chamber, then roducing water gas in the usual way, and than combining the water gas with the distilled. coal gas. v

In testimony whereof I have signed this spiwi'lication in the presence of two subscribing witnesses.
