GAS-PRODUCING. APPARATUS.

SPECIFICATION forming part of LettersPatent No. 703,943, dated Julyl, 1902.

- Application filed January-24, 1902. Serial No. 91,067. (No model) illuminating-gas, and the same co'mprehends' a novel, cooperative, and peculiar arrange ment of parts, all of which will hereinafter be fully described, and specifically-pointed out in the appended claims, reference being had to the accompanying drawings,in which- Figure 1 is a side elevation of my type ofgas apparatus looking in the direction of arrow a in Fig. 2, portions being broken away to better illustrate some of the parts. Fig. .2 is a plan view thereof. Fig. 3 is a horizontal'section of the same, taken practically on the line 3 3 of Fig. 1. Fig. 4 is a horizontal section taken on the line 4 4 of Fig. 1. Fig.5 is an end elevation of the apparatus, one of the generating-chambers being shown partly in cross-section. Fig. 6 is a detail side view,

partly in section, the latter being ta'ken the line 6 6 of Fig. 5 and lookinginthe direction of arrow 1) on Fig. 5.

In the practical construction myinvention includes a number of generating-compartments consisting of perpendicular chambers, three being shown in the drawings and designated by 1, 2, and 3. These chambers have a like construction, are disposed transversely of the complete structure and in parallel planes, their upperor crownportion being arched, as at 1, where they merge with'th'e front and rear walls, (indicated by w up) One of the said chambers, preferably the one designated as No. 1, communicates a't'the top with the vaporizing-chamber D for reasons presently explained.

Each of'thechambers 1, 2, and 3 has three doors d d d disposed in different horizontal planes, the upper one at of which covers the filling or feed openingf in the front wall w, the next lower end d covers the clinker-openingf, andthelowermost one 61 the ash-pit opening f Each

chamber

1, 2, and 3 has a grate g in a plane just below the opening f, as clearly shown in Fig. 5, and the several doors dd d each'have the usual latch devices, as shown.

opening f, so'that the fuel can be thrown in the

chambers

1, 2, and 3 and filled up to a point under the aforesaid chamber 4, as will be clearly understood by reference to Fig. 5. The chamber4 is formed of an approximately semicircular shell made of fire-clay, like a retort for fgasfand which extends through the end wall to andinto the end wall 20 at which point'itis closed by a cap-plate E, bolted to the sai'dshell." At the opposite end an extension l fis bolted to the shell l in the head of which is a door or manhole 4 and with this extension communicates a stack B, having a cut-off or closure valve b at the top.

P designates the gas-offtake pipe,conneoted with the extension 4. and whichdischarges into the water seal or purifying-tank G of any approved construction and having the usual oiftake or house-supply pipe P and water-pipe P as shown.

By providing a steel shell 4 and mounting it cooperatively with the other parts, as described, I canin case of necessity or desirability remove'said shell by disconnecting the extension 4 'jtherefrom and removing the cap plate'E and substituting a new shell therefor;

By referringnow to Fig. 3 it will be noticed theverticalwalls that separate chambers 1,

2, and 3 have openings 0 o to provide for circulation of the gaseous products from the vaporizing-chamber D to chamber 1 through chamber 2 and from thence to chamber 3, and from said chamber 3 the products pass up into the chamber 4, the latter having an inlet 4 directly over the chamber 3, as clearly shown in Fig. 3. v

The vaporizing-ohamber D, before referred to, extends vertically above the chamber 1, and said chamber D is in the nature of a wide stack, its upper end having a stack piece proper (indicated by B) and provided with a closure-valve, as shown.

chambers

1, 2, 3, and 4, chamber D, and the chamber 1, as before described, by reason of The chamber D has openings normally closed by hinged doors 8 8 and the interior of chamber D is made up of checker-brickwork (indicated by D to provide a maximum heat-surface for the oil to pass over.

H designates the valved crude-mineral-oilfeed pipe that discharges into the upper part of chamberD, and 10 10 10 designate the airblast tubes for the

chambers

1, 2, and 3, and 11 11 11 the valved steam-jet pipes for injecting steam under the grate-surfaces of

said chambers

1, 2, and 3.

The manner in which my producing apparatus is set in operation is best explained as follows: The

chambers

1, 2, and 3 are first filled with hard coal or coke within one foot of the bottom of the top openings 3. The doors tosaid chambers are then closed and the closure-valves on the stacks'B and B are opened. The blast-pipes that feed under the grates g are now opened and maintained until the blast is run up to a bright-orange heat. The blast-pipes are then closed and soft nutcoal is charged through the feed-openings f onto the top of fire to the desired height. The doors dare then closed, as are also the valves for stacks B andB, steam turned on under gratesg, and oil turned into the vaporizingchamber D. Taris then fed into No. 1 chamher by any suitableinjector means. The apparatus will now he generating gas, the time of runs in the practical operation of my invention being from ten to twenty-five minutes.

By arranging the several parts as described and charging the apparatus in the manner stated the nitrogen is driven otf and the desired gas product is left practically free of nitrogen. Furthermore, all of the heavy car- D0 is extracted from the tar fed into the its running through the several chambers. Again, my improved arrangement of parts presents a very large amount of heating-surface. The oil is vaporized in chamber D and caused to pass through the several chambers l, 2, 3, and 4, where it intermixes with the other products, the gaseous mixture passing from the cham ber4 to the seal and purifying devi'ces.

' Duringblastiugtheheat passes outthrough stacksB B. The greatest part, however, goes up through the checker-brickwork in the chamber D.

In practice the nut-coal that is charged into the

upright chambers

1, 2, and 3 is not drawn out, but remains in said chambers to keep up a fire-bed. Crude oil is mixed with the nut-coal for enriching.

In my construction of apparatus I am enabled to obtain, five hundred to six hundred 1 heat units as against three hundred and fifty units secured in water-gas and also have a complete combination of coal and water gas produced under a uniform and regular candle-power. It should also be stated that in operation when gas is making it passes through the partitions between the

several chambers

1, 2, and 3, which helps to break the small globules, and thereby more thoroughly fix the gas.

In charging the

chambers

1, 2, and 3 with soft nut-coal, as stated, I have the advantage of spreading it all over the surface of the fire, and after the gas is all drawn out of said coal it remains on the fire, and thereby no heat'is lost drawing it out and substituting cold fuel. Again, by providing for charging the nutcoal with a shovel the same can be easily made even over the surface of the fire and not in piles, as is usually the case when fed by magazines and hoppers.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a gas-producer of the character described, the combination with the main structure including the vertical walls thereof, a vertically-disposed generating-chamber, a valved stack therefor, and means for feeding vaporized oil into the said vertical chamber; of the horizontal chamber, consisting of a metal shell endwise slidable and detachably supported in the vertical walls of the main structure, said shell having an intake in communication with the generating-chamber, a closure-cap for one end of said shell, and an extension for the other end, provided with a valved draft flue or stack and gas-outlet, all being arranged substantially as shown and for the purposes described.

2. In a gas producing apparatus of the character described, comprising in combination, a main structure, having a series of parallel vertically-disposed generating-

chambers

1, 2 and 3, a blast and a steam-injector means cooperatively joined therewith, the division-walls between the

chambers

1, 2 and 3 having openings for joining said chambers, the horizontal chamber 4, having an opening in communication with the chamber 3, and having an extension provided with a valved stack and an outlet,'the vaporizer-chamber D, in communication with the chamber 1, and having a valved draft-stack and an oilsupply for said chamber D, all being arranged substantially as shown and for the purposes described.
