IMPRovEujAFPARATuS Specification forming part of Letters Patent No. 90,644, dated June 1, 1869 g reissue FOR GENERAflN AND CARBURETING GAS.

No. 3,745, dated November 30, 1869.

To all whom 'it may concern:

' Be it known that. I, GLEAVELAND F. DUNDER- DALE, of New York, -in the county and State ot' New York, have invented certain new and useful Improvements iu'an Apparatus for Generatin g Illuminating-Gras and I do hereby declare that the following is a full and exact de-l scription of the same, reference being had to the accompanyin g drawing, and tothe letters of reference marked thereon. y

The accompanying drawing represen ts a vertical section of my apparatus.

The nature of my inventionconsists in constrnctin g au apparatus `wherein hydrogen ,gas van be generated and carbureted by passing it through any suitable hydrocarbon liquid, so

' arra'ngedthattnedilu ted acid; nyo'fromwhich f the hydrogen is generated, and the hydrocarbon liquid are separated and in di'erent compartmeuts, but under the saine gasometer.

Apparatuses have been constructed for this purpose 5 but they have lfailed to be eicient in mixing the gases and vapors only in combining proportions and preventing the depositing of the vapors ofthe hydrocarbon in a liquid in the pipes, the reason beingthat the hydrocarbon liquid was placed in contact and iioating on the top of a mixture of the acid-and water, which, when the hydrogen was being generatedby the contact of scraps of met-al for that purpose, the reaction of the diluted acid and metal in freeing the hydrogen from the water created-an excess of heat, which caused the hydrocarbon liquid to evaporate too rapidly and carry overinto the pipes ot' the buildingan excess of the .hydrocarbon vapors,

more than the hydrogen would combinewith.

The diluted 'acid was also found to absorb part of the hydrocarbon liquid floating on its snrface. r

lv The construction and arrangement of my'apparatns obviates these drawbacks and diiicuL' ties by keeping the diluted acid and hydrocarbon liquid separated in dierentchambers or compartments under the same coverand in one machine, but at the same time permitting and forcing the hydrogen generated therein to pass through the hydrocarbon liquid as it rises in.a warm state from the contact of the metal scraps, and effecting a chemical and perma' nentcombination or mixture,` by which the hydrogen carries over only its combining proportions of the vapors-of the hydrocarbon liquid. This is donein my arrangementof apparatus in a manner automatically with the generation. The combining of the gases and vapors is only done as the gas is required by consumption, or .by being drawn oli', thereby` preventing a large collection of unused gas in the-apparatus.

` In the accompanying drawing one arrangement under this principle is -shown by which` lutd'acid andwater; B,it.he coverof the same, for holding the gas and regulating its manufacture.

C is a tank or reservoir lled withvwater, surrounding the tank'A, into which the bottom of the cover B is inserted, forming a seal around the'lower edges of the cylinder-cover or gasholder'B. .To the top ot this cover B a fnnnel-shaped cylinder, D,'is securely fastened, Y Vthe lower part of which is perforated with small holes n, and contains the iron shavings, or other suitable metal. l In the upper part of this cylinder D a perfectly-tight compartment, E, is made, provided with pipes F, through which the generated hydrogen gas is conveyed from the cylinder D, under the surface ot'- the hydrocarbon liquid contained in the chamber or coinpartment E. This annular chamber E, formed in the upper part of the cylinder D, which contaius the hydrocarbon liquid, is filled from the f pipe or opening G, closed by a suitable stopper or cock, and is'provided with several holes, M, through its external walls, for allowing the gases to'escape into the top cylinder or cover, B, after they h ave passed through the hydrocarbon liquid, and thereby have becomecarbui reted and ready-for use. .4

J is an opening secured byascrewcoverorits equivalent, through which the liron shavings, turnings, or other suitable metal are introduced into the cylinder D. u

H is a pipe passing through the top of the "cover B, and extending a llittle distance below the lower endof the cylinder D. This pipe is closed by a suitable stopper or cock, and is for s du 3,743

the purpose of supplying acid or water to the tank A, and is made a little longer than the cylinder D, for the -purpose of having its end always under water, being thereby sealed to prevent the escape of gas While filling the tank A. I

' K isla pipe, provided 'with a faucet, and arranged'a-little distance above the bottom 'of the tank A, for drawing 0E the contents of the tank, and is arranged above and clear from the bottom, to prevent it from being choked up by the crystals of the sulphate ot' iron or other metals which form on the bottom of the tankthe resultof the reaction of the acid and the metal scraps.

L is a pipe for the exit of 'the gas from the gas-holder or cover B, passing through Ythe lower part of the tank A, and extending upwardvwithin the reservoir or tank to about the level of the topthereoi. To the end of this pipe, on the outside of the tank, the servicepipe for supplying the gas to the burners is connected.

'The heavyshading or Water lines in the drawing shows the height of the diluted acid in the tank A, and the light shadingv or lining the height of the hydrocarbon liquid in the compartment E when the apparatus is filled for operation. y

The operation is as follows: The tank A is filled to a height as shown in the heavy lin ing With diluted suitable acid and the compartmentE with hydrocarbon liquid to a height as shown in the light lining, while the .lower part ol' the lfunnel-shaped cylinder D is lled with scrap-iron or other suitable metal the reaction of the acid upon which produces hydrogen. The operation commences by the y generation of hydrogen from thediluted acid and the material in the cylinder D, which is immersed therein. This hydrogen rises into the upper part of the cylinderD and escapes into the pipes -F, and is conveyed through said pipes under the surface of the hydrocarbon liquid in the reservoir or compartment E, and forcing its Way through the hydrocarbon liquid'comthrough pipe bines or mixes with the vapors of this hydrocarbon liquid in its due proportions, assisted by theheat and electricity evolved in the chemical react-ion between the acid-water and metals, which heat and electricity facilitate the combination of the hydrogen with the hydrocarbon vapors. The illuminating-gas thus obtained escapes through' the holes Minto the gasorneter or cover B, from whence it makes its egress L. When the gas is manufactured faster than it is consumed its accumulation within the gasometer or cover B causes said cover B to rise, lifting thereby the funnel-shaped cylinder D, oo ntaining the metal,

out of the diluted acid, and the generation ot' the hydrogen at once ceases, making'there'by the operation of the apparatus self-regulating,

according to its consumption, at the same time stopping the evaporation of the hydrocarbon liquid. The gas thus made is of .an exceedingly-brilliant character, giving a light equal to the best coal-gas, with only one-thirdk the consumption in volume.

What I claim as my invention, and desire to secure by Letters Patent, is

l. The manufacture of carbureted hydrogen gas by placing the hydrocarbon liquid and the diluted acid in different vessels or compartments, not in contact with each other, but in the same machine and under the same cover and near each other, for the purposes described.

2, The combination and arrangement of the cover B, containing thefunncl-shaped cylinder D and annular'charnber E, with pipes F and outlets M, the chamber D as a regulator, conductor for the hydrogen gas, and supporter for the hydroc'arbon-chainbefE, the rank A, Water-chamber G, and feed-pipe H, thefwhole being combined in the manner and for the purpose substantially as Vherein set forth and described.
