Letters Patent No. 113,317, dated April 4, 1871.

.IMPROVEMENT IN APPARATUS` FCR. CARBURETING AIR AND GAS.

The Schedule referred to in these Letters Patent and making part of the same.

To alt whom it may concern Be it known that I; FRANCIS H. LUTKEWITTE, of St. Louis, in the county of St. Louis and State of Missouri, have invented a new and .improved Illuminating Apparatus; and I do' hereby declare the following to be a full, clear, and exact description ot' the same, reference being had to the accompanying drawing making a part'of this specication. A peculiarly constructed.

My invention relates to a sectional carbureter, which -will be hereinafter fully described.

Figure 1 represents a side view;

Figure 2a top or bottom view; and

Figure 3, an end view.'

AVB O area series of horizontal sections, placed one above another, and connected or disconnected at their ends.

Each of tbese` is again subdivided into a series of sub-sections, A1 ALZA3 Bl B2 B3 O C2 C3, connected at their ends with one another.

Each of these sub-sections is again subdivided into small apartments D, in which is placed a quantity of capillary or absorbent material, in the well-known way, to enable the air to 'came in contact with the greatest -amount of hydrocarbon particles or surface.

a b c are the pipes through which the air isinjected by a suit-able air-pump or other apparatus of' analogous character. This forcesv the air through the absorbent and causes it to become saturated with hydrocarbon, when it is conveyed through pipes a.' b c to the burn ers or some receptacle.

' E are gauges, arranged in each sub-section, and notated so as to indicate the amount of hydrocarbon consumed.

The mode of operation is asfollows: y 4 If the Weather is' cold (as, for instance, at `zero,) the air and hydrocarbon will be considerably densied and increased in specific gravity. This will canse a less surface contact to take place when they are brought togetheig'and hence will require a given quantity oi' air to be passed through the largest quantity or maxi mum of hydrocarbon, in order to give the requisite illuminating power. I, therefore, enter the air at the first pipe, on the bottom, and'into right-hand sub-sec-` tion Al of section O. I then force it through charnbers D until it arrives at the farther end thereof, where it passes laterally into subsection A2, and then on through sub-section A3, all of section O; thence it passes up into section B; here it moves along through the saturated absorbent untilit arrives at the end of the sub-sections oi' this section. Then it passes, in like manner, through all the sub-sections of section A into Vpipe Gl and out of the discharge-pipe a into the burner or receptacle. If, again, the temperature is moderate, as in the spring or fall, the air is rarer and the hydrocarbon less dense- I then shut oh" one, two, or all the sub-sections of section G, according to the degreeof temperature which prevails at any partielllar time, by turning the cocks inthe air-inlet pipes b c d, commencing at the right, and taking one after another toward the left. Again, in summer, when the Vtemperature is high and the air and oil are both much' expanded by the interpressure of heat, I throw out two whole sections inthe saine way. p

Whether applied on a large or small scale it will be perceived that I can graduate to a. nicety, and in a moment, the quantity of' hydrocarbon through which a given amount of air must pass, and the duration of contact between the two substances, which will secure the precise commicture desired'.

Exactuess, in the relative proportions of the two substances, is a sine qua non in producing the best light. This can nevell be produced and uniformity in the quality of gas secured, except on the principle of graduation according to temperature. V

Having thus described all that is necessary to a full understanding of my-invention,

. What I esteem to be new, and desire to protect by Letters Patent, is'

The sectional carbureter herein described, consisting essentially of the horizontal sections A B G, placed one above another, and subdivided into a series of sub-sections, which are subdivided intc small apartments D by vertical partitions, every alternate one of' which is openat both top and bottom, and the others at bottom only, the said horizontal sections being connected at one end by the inlet-pipes a b c, and at the other end by the outlet-pipes c b a', and each provided with a gauge, E, all constructed as and for the purposespeciiied.
