APPARATUS FOR IMPREGNATING AIR WITHHYDROCARBON VAPOR.

SPECIFICATION forming part of Letters Patent No. 355,594, dated January 4, 1887."

Application filed March 4, 1856. Serial No 194,036: (No model.) Patented in England September 11, 1885, No. 10,786.

I 0 aZZ whom it may concern.-

Be it known that I, GOTTLIEB DAIMLER, a citizen of IViirtemberg, residing at Gannstadt,

in the Kingdom of Wiirtemberg and Empire of Germany, have invented a new and useful paratus, and Fig. 2 a plan.

The apparatus consists of a receptacle, A, charged with petroleum, in which is a float, B, having a central small hole, 0, above which is formed a cavity or basin, D, into which the petroleum enters through the hole 0, so as to stand therein at the same level as outside the float. To the bottom of the basin is fixed a central tube, E, which passes freely into the.

tube F on the cover of the vessel A, so as to slide up or down in the same,according as the float rises or falls with any alteration of the petroleum-level. The lower end of the tube E is perforated, so that the air drawn in through the tube will issue in finely-divided streams through the perforations'into the petroleum in the basin, and thus becomes impregnated with the vapor thereof.

\Vhen the apparatus is used in connection with a petroleum motor-engine, the tube G is connected to the inlet-port of the engine, so that during the suction-stroke of the latter atmospheric air is drawn in through thepipesF and E, and after bubbling up through the petroleum and becoming impregnated therewith, as described, it passes through the spaces H I J and pipe G into the cylinder of the engine.

The airsupply is, by preference, heated previously to its entrance into the apparatus, either by the waste heat of the motor-engine, in the manner described in my application for a patent, No. 179,692, or by a special application of heat, in order to facilitate the evaporation of the petroleum or to make good the heat absorbed by such evaporation. The float is provided with a projecting inwardly-bent rim, K,

anda shield, L, whereby the impregnated air passing up from the basin D will be deflected in its course, and thus be made to deposit within the rim any particles of liquid hydrocarbon it may carry with it, and which then flow back into the basin. By this arrangement, and by effecting the communication be: tween the basin and the other contents of the reservoir through a very small hole, the two uniform evaporative action is insured, no matter what the quantity of petroleum contained in the vessel A may be.

By arranging the tube E centrally in the reservoir A the immersion of the perforated part thereof to-an approximately constant depth will be insured, notwithstanding that the apparatus may occasionally assumea more or less inclined position. p

Before passing from the apparatus to the motor-engine the impregnated air is made first to pass round a second baffle-plate, M, and through holes N into the chamber I, so as to be effectually deprived of all liquid particles, and from I it passes through the wire-gauze 0r perforated partition 0 into the chamber J,

which is provided at top with a safety-valve,

P, so that in the event of the igniting-flame of the engine striking back through the pipe Gr it will only extend as far as the partition 0, and any rise of pressure resulting therefrom will escape through the valve 1?.

I amtaware that a gas-carburetor has heretofore been composed of an oil-tank having a supply-pipe and vent-opening and inlet and outlet pipes for the gas, a floating carburetor having an oil-chamber supplied by bottom pipes to the plane of displacement, and an influx-chamber leading the gas by a series of bent pipes to and into the liquid-surface of the oil-chamber, whence, charged with the ICO vaporized hydrocarbon, it expands into the upper part of the oil-tank through the open top of the oil-chamber in the float and passes off through the outlet-pipe. that in another instance an air and gas carburetor has been composed of an oil-tank, a float therein consisting of radial chambers, a top perforated division-plate and wicks hung in said chambers, said tank having gas and air inlets and the float having a top flexible pipe through which air is forced thereinto and a bottom flexible tube through which the oil in the tank enters the float, so that the level of the oil in the tank and in the float is always maintained. My invention differs from the above in that I provide a float containing a basin open at its top and in communication only with the main body of liquid in the oilvessel through a small hole in the bottom of the tank, so that while the liquid is maintained in the basin at the same level as the main body it is practically isolated from the same as regards heat, combined with an air-tube fixed to the float and basin and communicating with the petroleum in the latter through perforations below the level thereof, and a tube on the cover of the oil-vessel leading to a supply of heated air, and in which the perforated airtube freely slides. I also provide in connection with the aforesaid novel features a chamber through which the impregnated air from the basin passes to the outlet-pipe leading to a gas-engine, said chamber containing an automaticallyoperating safety-valve, whereby any pressure produced within said chamber, owing to the igniting-flame of the engine striking back into the chamber, is liberated, in which novel feature, as well as in the construction of the carburetor before explained, my invention differs from combined gas engines and carburetors as heretofore constructed.

Having thus described the nature of my invention and the best means I know for carrying the same into practical effect, I claim- 1. The combination of the vesselA, for containing the main body of petroleum, the float B, having a central small hole, 0, and the interior petroleum-basin, D, supplied through the said hole and open at its top into the vessel, and the telescopic air-tubes E and F, sliding one within the other, the outer tube being open for connecting with a supply of heated air, and the interior sliding tube having perforations within thebasin below the level of the petroleum therein and having its lower end open and in communication with the said hole for conveying the petroleum therethrough to the basin, substantially as described.

2; The combination of the vessel A, for containing the main body of petroleum, the float B, having a central small hole, 0, and the interior petroleum-basin, D, supplied through the said hole and open at its top, the tele- I am also aware scopie air-tubes E and F, sliding one within the other, the outer tube for connecting with a supply of heated air, and the interior sliding tube having perforations within the basin and below the level of the petroleum therein, the baffle-plate L, fixedabove the open top of the basin, and the inwardly-bent rim K, substantially as and for the purpose described.

3. The combination of the vessel A, for containing the main body of petroleum, the float B, having a small hole, 0, and interior petroleum-basin, D, open at its topinto the vessel, the telescopic air-tubes E and F, sliding one within the other, the outer tube for conneeting with a supplyof heated air and the inner sliding tube communicating at its lower end with the said hole and with the basin below the level of the petroleum therein, the chamber J, having a perforated partition, 0. and discharge-pipe G, and the safety-valve P at the top of the chamber above the discharge pipe, substantially as and for the purposes de scribed.

4. In apparatus for impregnating air with petroleum vapor, a float, B, having a basin, D, open at its top directly into the receptacle and communicating with the main body of liquid only through the small hole 0, so that while the liquid is maintained in the basin at the same level as the main body it is practi eally isolated from the same as regards heat, said float having an air-tube, E, communit eating with the petroleum in the basin by perforations below the level thereof and sliding freely in the tube F on the cover leading to a supply of heated air, substantially as and for the purposes set forth.

5. In combination with the float B, basin D, and perforated air-tube E, the projecting rim K and baffle-plate L, for retaining any liquid petroleum carried up by the air and returning the same to the basin, substantially as herein described,

6. The combination, with the petroleum-vessel A, the float B, having the petroleum-basin D, and the perforated airconducting tube -E, communicating with the basin below the level of the petroleum therein, of the chamber J, in communication with the "essel and through which the impregnated air passes away, and

the safety-valve P at the top of the said chamber, whereby any pressure produced in the latter from the flame of the impregnated air passing back to the chamber is liberated, substantially as and for the purposes set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 13th day of February, A. D. 1886.

GOTTLIEB DAIMLER. Witnesses:
