initrd Stairs @sind @Mina IMPROVED APPARATUS FOR CAIRB'URETTING- AIR OR GAS.

The Schedule referred to in these Letters Patent `a'nd making part; of the same.

To `all whom t ma/y concern:

Be it known that I, J osrAH Jonson, of Toledo, in the county of Lucas, and State of Ohio, have invented a new and improved Gas-Generator and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, makinga part of this specification, in which my invention is represented by a vertical axial section.

The object of this invention is to provide, for public use, a cheap, convenient, and substantial carburetter, the action of which can be so adjustedyand controlled as to present a greater or less carburetting surface to the air, whereby the latter can be combined with any required proportion of inflammable vapor, without changing the draught or quantity of air.

In the drawings- A represents the carbnretting-vessel, which is divided by horizontal partitions, a* a2 a3, into four or more chambers, A1 A2 A3 A4, and is surmounted by a gasometer, G, the top of which `may be held down by a spring g, and the space between which and the upper edges of the vessel A may be packed and sealed in any suitable manner.

B is the cock, through which the gasoline or other -carburettingmatcrial is introduced.

C is the pipe, through which the supply of fresh air is introduced, said air first passing through a heater, H, and then down, and in through the wall, under the partition a2, so as to be discharged into the chamber A3, in contact with the surface of the gasoline in the chamber.

D represents the exit-pipe, through which thecarburetted air is discharged from the'gasoline-chambers into the gasometer, said pipe being connected with said chambers by means of branches, Dl D2 D3, each of which has a stop-cock, dl d2 da.

Each of the partitions acl a2 is provided with a tube, e e1 c2, extending downward from it, said tube being closed at its lower end, by a oat-valve, e.

The two chambers AdA3 are ea'ch provided with a waste-pipe, i? is, by which the gasoline, whenl arrivingl at acertain height, will ow into the chamber next below.

S is a sponge, designed to take up the gasoline by capillary attraction, and promote its vaporzation.

The partition a? is provided with one or more openings, m. y

O is the delivery-pipe, which connects both with the i gasometer and the chamber A4, by means of branches,

Ol 02, so that, by turning a stop-cock, ol or o2, the gas may be drawn for use, either from the former chamber or from the latter. v The operation of the apparatus is as follows: The gasoline is introduced through cock B, and,

running down through tube c2, it fills chamber A3 to the height of tube i3, when it runs down into the next chamber A, lling that to the height of tube i?, when it passes to the lower chamber, A1, filling that till the float-valve stops it from entering.

Or, the float-valves maybe so arranged'that the gasoline will pass freely through all the pipes, e e e2, to the lower` chamber, which it will ll, until it raises the valve, and cuts o'ii the passage into that chamber, when it will ll the chamber above, until, in turn, it closes the Valve there,` after which it will, in like manner, fill chamber A3,'till it cuts oi the supply, when, after thus filling the lower chambers, it will rise in chamber A, to any height required.

The latter is the preferable construction, since, by its means, the supply can be better adjusted, and the upper chamber A4 can be made to act as a reservoir, to automatically fill the three lower chambers as fast as the duid within them wastes away.

If the two lower stop-cocks, dl d2, are closed, and

the upper -one opened, the air introduced through pipe O will pass across over the gasoline in chamber A3, and, taking up but little of the vapor, will escape directly through cock d3, filling the gasometer and chamber Awith a gas of comparatively poor qual- If the middle cock, d, be opened, and the others closed, the air from pipe C will not only pass over the same surface of fluid as before, but, going down through pipe t3, into chamber A2, will pass over the fluid therein, and escape through cock d2, much richer than before.

And, likewise, if the lower cock, d, be opened, the two upper ones being closed, the air from pipe C will be obliged to travel over the gasoline in all threeof the chambers A3 A2 A, before it can escape through branch Dl into the 'gasometen When gasoline is allowed to stand in chamber A, its evaporation also -will enrich the gas that has already passed over through pipe D.

If there should, in consequence of this, orwhen first lling the apparatus, be any diiference between the richness of ,the gas in chamber A4 and gasometer G, i t can be taken for use from either, or from both of .said chambers at once, by means of two branches, O 02 and cocks ol o2, so as to regulate the qualityfas may be desired.

The whole apparatus is simple in construction, cheap, economical in operation, and not liable to get out of order, or cause accidents of any kind.

As will have been already clearly understood, from.

the above description, it will enable the operator, by

'properly adjusting the stop-cocks, to produce and draw off for use gas or carburetted air of any degree of richness of illuminating-quality that may be desirable.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

1. The arrangement of a series of chambers, A A A3, pipes e e1 e2, 2 3, valves fu v fv, supply-pipe O, and exit-pipes D D2 D3, having cookedl d2 d3, in such a manner as to operate substantially as and for the purposes set forth.,

2. In connection with the several parts, thus arlranged and operating, the arrangement and ootnbination ofthe delivery-pipe O, having two branches,
